Chronic kidney diseases are considered one of the main global health challenges, causing high rates of morbidity and mortality, which creates a significant burden on individuals and communities. Traditional Chinese medicine plays an important role in managing these diseases, particularly herbs like Rhubarb and Astragalus. This article aims to explore the effectiveness of the components of these plants, specifically the anthraquinone from Rhubarb and the saponins from Astragalus, in treating kidney fibrosis caused by ureteral obstruction. We also highlight the challenges associated with achieving synergistic effects between these components and present a strategy to develop composite granules to enhance the effectiveness of these treatments. In this study, we will explore how to enhance the absorption of these components and regulate the gut microbiome, thereby boosting the potential of traditional Chinese medicine in treating chronic kidney diseases.
Introduction to Chronic Kidney Failure and Its Relationship with Kidney Fibrosis
Chronic Kidney Disease (CKD) is one of the main public health issues globally, associated with high rates of mortality and suffering. Chronic kidney failure raises significant concern in societies due to the considerable burden it places on individuals and healthcare systems. The core problem in chronic kidney failure lies in the development of kidney fibrosis, manifested by increased proliferation of kidney cells and growth of connective tissue, leading to irreversible deterioration of kidney function. There are few therapeutic approaches that directly target kidney fibrosis, thus maintaining kidney health and preventing disease progression is crucial.
In recent years, numerous studies have shown that traditional Chinese medicine (TCM) has significant potential in treating chronic kidney failure. Both “Rhubarb” (Rheum palmatum L.) and “Astragalus” (Radix astragali) are commonly used components in treatment, having proven successful in improving kidney failure conditions and achieving positive outcomes in treating kidney fibrosis. Formulations containing these ingredients have been used for decades, demonstrating their benefits in alleviating symptoms and disease progression.
The Active Composition of Rhubarb and Astragalus
Active components are considered key elements in treating chronic kidney failure, among which the total anthraquinones (TRA) and total saponins from Astragalus (TAS) are among the most effective. These components are characterized by their clear chemical structure and stability, making them preferable to using whole herbs. Research indicates that the anthraquinones in Rhubarb reduce kidney fibrosis by inhibiting specific signaling pathways, including TGF-β/Smad. On the other hand, saponins from Astragalus improve the state of kidney failure by affecting the same signaling pathways.
Modifications in the gut microbiota play a vital role in managing kidney failure. Research has shown that kidney failure can be treated by regulating the gut flora using polysaccharides like Astragalus Polysaccharides (APS). These polysaccharides contribute to improving the patient’s condition by enhancing diversity and increasing the number of beneficial bacteria in the gut.
Drug Delivery Strategies and Preparation Techniques
Modern drug delivery techniques are vital for enhancing the effectiveness of Rhubarb and Astragalus. To achieve this, a self-nanoemulsifying drug delivery system (SNEDDS) was developed to improve the oral absorption of these components. This system enhances solubility, facilitating the transfer of drugs to the lymphatic system. Granules loaded with these components are designed to ensure their stability and enhance their loading capacity.
Research indicates the importance of using granules with targeted drug delivery systems, as they provide a form of multiple dosing that facilitates the delivery of formulations to specific sites in the gastrointestinal tract, positively affecting treatment outcomes. Systems related to time-released and sustained release of components in the intestines have been approved, ensuring coordinated effectiveness of the treatment.
The Effect
Therapeutic for Combined Granules on Renal Failure
Clinical trials on the model of unilateral ureteral obstruction (UUO) induced renal failure showed that the intake of combined granules significantly improved the histopathological condition of the kidneys, with a noted reduction in collagen deposition and levels of inflammatory cytokines. These granules contribute to restoring the balance in the gut flora affected by surgical interventions, thereby enhancing the intestinal barrier and reducing inflammation.
Methods for treating renal failure increasingly rely on effectively delivering components of traditional Chinese medicine. Combining anthraquinones from rhubarb and saponins from astragalus with polysaccharides from astragalus provides a promising strategy for integrative and sustainable treatment of chronic renal failure. These communications aim to accelerate healing and improve the quality of life for patients, offering new possibilities for future therapeutic strategies.
Preparation of Pharmaceutical Pellets
The process of preparing the pellets starts with the application of advanced techniques aimed at improving the drug’s effectiveness by reducing side effects and increasing its duration of action. In this context, a fluidized bed system was used to prepare MCC pellets, where a solution of hydroxypropyl methylcellulose (HPMC) was sprayed onto the MCC pellets. The spraying technique relies on atmospheric pressure (1 bar) and inlet temperature (50-55 degrees Celsius), ensuring even distribution of the solution over the pellets.
After achieving the desired weight gain (20%) through spraying, an additional layer using Eudragit L100 was applied, which is a type of coating that provides the pellets with the property of continuity and release at specific times according to stomach pH. This layer is essential to secure sustained release of the drug in the stomach and intestines.
The pellets were then processed in a vacuum oven at 40 degrees Celsius for two hours to effectively dry them and reduce moisture resulting from the spraying process, aiding in maintaining the pellets’ stability and enhancing their shelf life. Such procedures contribute to achieving significant improvements in the physical properties of the pellets such as density and flowability.
Analysis of Drug Release
Drug release analysis represents a vital step in understanding how a drug can work and affect the body. The drug release from the pellets with various formulations was studied using a USP Dissolution device. The pellets were exposed to different levels of acidity and specific times to determine their effectiveness over time.
For example, different solutions such as hydrochloric acid and phosphate buffer were used to replicate actual biological conditions. Periodic samples were taken during the process to analyze the concentration of active ingredients such as aloin, emodin, and bision. An approved HPLC method was employed to analyze these concentrations, allowing for precise measurement of changes in the release ratio over 24 hours.
Release compatibility between TRA and TAS formulations was evaluated using the similarity factor f2, which helps provide a clear picture of the effectiveness of different formulations. The results provide valuable information on how combined drugs can enhance the effectiveness of traditional therapies and medications.
Ureteral Obstruction Model and Treatments
Ureteral obstruction models are a key experimental tool for understanding various kidney diseases and the interaction between different treatments. The unconventional unilateral ureteral obstruction (UUO) model was applied to experimental mice to measure the effect of the pharmaceutical formulations used in treatment. Each group of mice was allowed to receive different formulations and standard treatment criteria, enabling comparison between traditional previous treatments and modern therapeutic forms.
Cut-off treatments included the use of drugs such as benazepril, in addition to formulations containing TRA/TAS.

DNA analysis techniques were used to identify genetic changes within the microbiome and contribute to the body’s ability to respond to various treatments. Focus was placed on extracting and analyzing 16S rDNA remotely, which enables detailed mapping of the type and number of microbial organisms residing in the digestive system of each group of mice.
This information helps clarify the relationship between prominent clinical features and the presence of acidity or precise balance in microbes, providing a comprehensive view of the role of microbes in enhancing health benefits or explaining specific complications based on the quality of diet and treatment.
Preparation of APS and TRA/TAS Granules
An advanced technique was used to prepare APS and TRA/TAS granules, where process parameters such as spray pressure, inlet temperature, and air speed in the drug layer coating process for APS granules were optimized. The results showed that using a sampling rate of 5 cycles per minute and a concentration of 20% (w/w) of APS led to the formation of smooth and uniform layers, achieving a yield ratio exceeding 98.5%. Upon completion of the coating process, the granules were coated with a concentration of 20% (w/w) of HPMC and 20% of Eudragit L100 sequentially. Eudragit L100 was significant for containing pH-sensitive properties that helped prevent the release of APS in the upper gastrointestinal tract. Furthermore, the combination of HPMC and Eudragit L100 contributed to ensuring a continuous and targeted drug release, leading to improved regulation of gut microbes.
Properties of TRA/TAS and APS Granules
The structural properties of APS and TRA/TAS granules reflect their effectiveness in clinical application. The granules form as white spheres while JRA/TAS appear as yellow spheres. Under electron microscopy, it shows that the granules have a spherical shape and a smooth surface, indicating that the preparation process was effective in eliminating any oil spills, which also signifies the effectiveness of the manufacturing techniques used. The particle size for both types of granules falls within the range of 750 to 1000 micrometers, enhancing their suitability for use in hard capsules. Additionally, the flow properties of the granules were evaluated, where laboratory flow results showed promising outcomes.
Drug Release Behavior from the Granules
The granules in the current study were subjected to drug release evaluation in different pH environments representing the gastrointestinal tract. The results showed that the initial release of TRA and TAS exceeded 80% and 60% within 10 minutes, indicating a significant increase in their solubility. However, no release of APS from the granules was observed in strong acids, demonstrating the efficiency of the coating layer in preventing drug release in the stomach. The granules responded differently depending on changes in pH, starting the release of APS in a neutral pH environment followed by a noticeable slowdown, allowing it to reach the lower intestine before being released gradually.
Therapeutic Efficacy of CPs Granules in Live Experiments
In experimental studies, CPs granules exhibited a notable effect in alleviating kidney fibrosis resulting from urinary obstruction. Compared to the control group, histological examinations revealed a significant improvement in renal tissue condition, with marked reductions in fibrotic parameters when using CPs granules. The expression of extracellular matrix components was also examined, where a decrease in collagen and fibronectin expression was observed in renal tissues after treatment, demonstrating the positive effect of CPs granules on restoring kidney functions. This was confirmed by evidence from immunoassays and functional studies highlighting the role of TGF-β in the kidney fibrosis pathway, and how treatment with CPs granules can inhibit this pathway.
The Direction
The Future of Research and Treatment
Research into CPs microparticles represents a significant step in therapeutic delivery systems. With the increasing understanding of how drug release is organized in the gastrointestinal tract, this can contribute to the development of more effective and customizable therapeutic systems based on individual patient needs.

Future research will also contribute to improving clinical applications and offering new options for patients suffering from chronic diseases.
Kidney Inflammation and Its Role in Kidney Diseases
Kidney inflammation plays a vital role in the onset and progression of kidney diseases, with studies indicating that it significantly contributes to the worsening of kidney health. Inflammatory cells, such as macrophages and T cells, release pro-inflammatory cytokines and chemokines that activate fibroblasts and increase the deposition of extracellular matrix proteins. Inflammatory signals derived from macrophages, such as NF-κB, TNF-α, and TGF-β, can exacerbate kidney fibrosis. Meanwhile, a decrease in anti-fibrotic factors such as IL-10 and BMP-7 has been reported during the development of kidney diseases. Serum levels of inflammatory cytokines like IL-6, IFN-γ, and TNF-α are significant in this context, as results from ELISA kits have shown marked increases in these cytokines in mouse models alongside a decrease in IL-10. This reinforces the idea that addressing kidney fibrosis should focus on reducing such inflammation.
Effect of CPs Formulations on Gut Microbiome
The impact of CPs formulations on the gut microbiome of model mice was examined through 16S rDNA sequencing analysis of stool samples. While no significant changes in alpha diversity among different groups were observed, PCoA and NMDS analyses showed a separation in gut microbiome composition between the model and sham groups. The dynamic balance in the gut microbiome and its metabolic management is primarily dominated by Firmicutes and Proteobacteria, with an increase in the abundance of these species potentially adversely affecting the host’s metabolic processes. These changes have also been associated with inflammatory responses in patients with chronic kidney disease, thus worsening kidney function.
Restoring Intestinal Barrier Function through CPs
The results demonstrate the importance of managing CPs formulations in restoring the balance of the gut microbiome and supporting intestinal barrier function. Data indicates that the formulations exhibited a significant ability to reduce levels of gut-derived toxins such as TMAO, IS, and PCS. This suggests a positive effect on restoring intestinal barrier function, which helps alleviate the exacerbation of kidney injuries. Immunostaining techniques were performed to assess levels of proteins such as occludin and claudin, where the results demonstrated a clear protective effect of CPs formulations, affirming their effectiveness in safeguarding the intestinal mucosal barrier.
Research on Multipart Drug Delivery Systems
Studies have shown remarkable success in developing composite tablets carrying TRA/TAS and APS, enabling an integrated treatment for kidney fibrosis. The developed system allows consistent delivery of therapeutic components to various parts of the gastrointestinal tract through a spatiotemporal delivery mechanism. This system represents a promising strategy for drug delivery and offers new opportunities to explore the effects of natural formulations within traditional Chinese medicine for the treatment of chronic diseases. This development encourages further research into the use of MUPS platforms and spatiotemporal delivery of multiple components of traditional Chinese medicine, enhancing future therapeutic applications.
The Role
The Vital Role of APS in Treatment
The conclusions clearly indicate that APS plays a vital role in the therapeutic effectiveness of CPs combinations by regulating the gut microbiome and protecting intestinal barriers. These effects underscore the increasing importance of incorporating traditional therapeutic components into modern medications, as they provide new approaches to handling complex chronic conditions such as kidney fibrosis.

Introduction to Chronic Kidney Disease and Its Consequences
Chronic Kidney Disease (CKD) is considered one of the major public health issues worldwide, causing high rates of morbidity and mortality, posing a significant burden on individuals and society. End-stage renal failure (ESRF) represents one of the largest negative outcomes of chronic kidney disease, with kidney fibrosis being a common pathway leading to this failure, characterized by increased proliferation of fibroblasts in kidney tissue and accumulation of extracellular matrix. This leads to the destruction of kidney tissue and irreversible loss of kidney function. Additionally, the effects of kidney fibrosis extend to negative impacts on heart health, reflecting the seriousness of the situation. To avoid this complex scenario, there should be a focus on developing effective strategies that slow the progression of kidney fibrosis, ensuring improved quality of life for patients and reduced healthcare costs.
Traditional Treatment Strategies and Their Effect on Kidney Fibrosis
Currently available therapeutic strategies to prevent the progression of chronic kidney disease include technologies such as angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs). However, this work is considered limited to scaling instead of making genuine efforts to treat kidney fibrosis itself. Focusing on new therapeutic methods, especially those derived from Traditional Chinese Medicine (TCM), is both intriguing and promising. Specific combinations of herbal medicines, such as rhubarb (Rheum palmatum L.) and astragalus (Radix astragali), are used as means to improve the health condition of patients with kidney fibrosis. Studies suggest that the use of rhubarb and astragalus may lead to significant improvement in kidney fibrosis, enhancing experiential evidence that includes over two decades of clinical use.
Studying the Mechanisms of Action and Interaction of Natural Treatments
The main biological mechanism of herbal medicines derived from rhubarb and astragalus revolves around regulating signaling pathways such as TGF-β1/Smad and NF-κB. Research indicates that key active compounds such as anthraquinone found in rhubarb and saponins found in astragalus enhance therapeutic effects by inhibiting fibrosis-inducing signaling pathways. These complex mechanisms lead to reduced destruction of kidney tissue, thus mitigating functional decline. Additionally, new data suggest that changes in gut microbiota play a crucial role in the development of chronic kidney disease, encouraging research into microbiota transfer strategies, such as the use of probiotics and plant polysaccharides, to mitigate the effects of fibrosis and arrange nutritional systems for patients and microbes.
Challenges
Pharmaceutical and Therapeutic Systems
Despite the potential benefits of natural formulations, one of the biggest obstacles they face is the limited aqueous solubility of compounds like TRA and TAS. Drug delivery techniques such as self-nanoemulsifying drug delivery systems (SNEDDS) are recommended to enhance the oral absorption of these compounds. Gel systems such as SNEDDS offer an effective means to improve the bioavailability of active ingredients. Other methods, such as innovations based on hydrogel technology and pH-dependent systems, contribute to overcoming the barriers that active compounds face on their journey to reach target areas in the digestive system.

Given the complexities associated with treating chronic kidney disease, the need for more research and innovation in therapeutic directions remains vital to harnessing the therapeutic potentials of nature.
Preparation and Characterization of Granules
Granules play a crucial role in enhancing drug efficacy and improving therapeutic efficiency. A fluid bed system has been used to prepare APS and TRA/TAS granules, where parameters such as spray pressure, inlet temperature, and fluidizing air speed during the coating of drugs were optimized. Achieving a balance between granule quality and loading efficiency is essential. After a trial confirming no agglomeration of the tablets at the desired level, a sampling rate of 5 cycles per minute was achieved using a concentration of APS at 20% (weight/weight), leading to the formation of smooth and homogeneous granules with a yield of 98.5%.
Following the coating process, the granules were covered with HPMC at a concentration of 20% (weight/weight) and then Eudragit L100 was applied. HPMC has low viscosity, which contributes to sustained process effectiveness while increasing processing time. This mixture is very suitable for achieving targeted drug release at the target site, facilitating control over intestinal microbes. Eudragit L100 plays a significant role in preventing the early release of APS in the upper gastrointestinal tract due to its sensitivity to pH levels.
Before establishing TRA/TAS granules, the SNEDDS formulation was optimized based on a ternary phase diagram. Experiments demonstrated that the ratio of TRA/TAS for EL35 type, ethylene glycol, and ethyl oil at 21:14:15 resulted in transparent and homogeneous mixtures, indicating the ability to achieve particle sizes of 33.01 ± 0.12 nanometers. The SNEDDS formulation contains concentrations of TRA and TAS quantified at 6.29 ± 0.07 mg/g and 8.80 ± 0.11 mg/g respectively.
APS granules appeared as white spheres, while TRA/TAS granules were yellow spherical cakes. Structural details using scanning electron microscopy (SEM) showed that the granules had a spherical shape with a smooth surface, indicating that TRA/TAS granules underwent an effective drying process without any oil appearance, demonstrating the success of the loading process.
In Vitro Drug Release
Evaluating drug release is a vital part of developing new drug formulations. A paddle apparatus of the CHP type was used to evaluate drug release, maintaining control conditions such as a temperature of 37 degrees Celsius ± 0.5 and stirring speed of 100 rpm. Initially, the granules were exposed to 900 mL of 0.1 M hydrochloric acid solution for two hours, after which the dissolution medium was changed to phosphate-buffered saline (PBS) with a pH of 6.8 for an additional 4 hours. Subsequently, the dissolution medium was adjusted to PBS at pH 7.4, and the dissolution was conducted over 24 hours.
The results showed that…
Samples were taken from various media to analyze specific components such as aloe-emodin, rhein, emodin, chrysophanol, and physcion; while the APS content was measured using the phenol-sulfuric acid method. All experiments were conducted in triplicates, ensuring the accuracy of the results. The similarity factor (f2) was also used to evaluate the synchronization between the release of TRA and TAS, which is an important criterion in studies of such formulations.
It is worth noting the importance of the environmental state on drug release. Environmental factors such as temperature and pH alter the secretion rates, necessitating careful consideration of results from such studies and the need for varying amounts of the drug according to each individual case.
Furthermore, it is essential to study how drug release impacts inflammatory factors and the intestinal environment, where specialized cells may play a crucial role in enhancing gut microbial balance. Advancements in drug release research contribute to the development of strategies that can enhance the efficacy of new treatments while reducing the side effects associated with traditional medications.
Unilateral Ureteral Obstruction Model and Treatments
The unilateral ureteral obstruction (UUO) model was employed in healthy mice to study the effects of new treatments in addressing renal fibrosis resulting from ureteral obstruction. This model includes surgical procedures as treatments to understand the biological effects resulting from the obstruction. The left ureter was isolated, paving the way for ligation, while the sham group manipulated the ureter wall itself without ligation.
Mice were divided into different groups according to the treatment: sham group, model group, BNPL (Benazepril) group, R&A group receiving the TRA/TAS formulation, and two other groups receiving APS and CPs. The various formulations were administered daily for 21 days following recovery from surgery. This design helps in understanding how different treatments may affect kidney function and disease progression.
Fecal samples were collected from all groups along with blood samples to study the intestinal microbiota and analyze inflammation markers. These processes are essential in understanding how different treatments can lead to improvements in metabolic health and how this impacts gut bacteria composition.
The use of modern techniques in studying rheumatic-related diseases, such as cytokine levels, is conducted through techniques like ELISA, where cytokine levels such as IL-6 and IL-10 can be measured to build a comprehensive picture of health status progression. Enhancing understanding in this area may contribute to the development of innovative therapeutic strategies.
Analysis of Gut Bacteria
The analysis of gut microbiota plays an important role in understanding the relationship between medications and their effects on the natural microbes within the gut. Fecal samples from mice are vital for studying microbial diversity through techniques such as 16S rRNA sequencing. During this process, DNA is extracted from the samples using a pure alcohol method, and researchers study the microbial composition of the microorganisms present.
The steps involved in conducting the analysis include DNA extraction as well as using PCR techniques for amplification, followed by result analysis. A significant change in microbial composition can occur due to treatment with different drugs, thus careful monitoring during the experiment serves as a useful means to discover how various treatments affect microbial diversity.
This knowledge is used to gauge more information about how gut microbiota can impact the response to therapies, especially with drugs that affect the gut environment. These studies reveal key relationships that aid in understanding how to develop tailored treatments for different medical conditions.
Material Characteristics and Dispersive Analysis
The physical properties of the spheres produced from two different types were studied, where it was observed that the particle dimensions of the spheres were within the range of 750-1000 micrometers. The bulk density of these spheres is approximately 0.62 grams/cm³, indicating their excellent ability to fill the hard capsules. These characteristics reflect the high quality of these spheres and contribute to achieving effective performance of the therapeutic drugs in pharmaceutical applications. The physical properties indicate the potential for improving drug absorption within the body, enhancing the therapeutic efficacy of the therapeutic agents and active compounds present in the pharmaceutical formulations.
Behavior
Release of Active Ingredients from the Balls
The balls underwent tests for the release of active ingredients (TRA, TAS, APS) in acidic environments representing the gastrointestinal tract. When these balls were tested in an acidic medium (0.1 M HCl, pH 1.2), the results showed that TRA and TAS released more than 80% and 60% of their respective payloads, respectively, during the first ten minutes, while no dissolution of either TRA or TAS was observed in the raw state, indicating a significant increase in their solubility via the SNEDDS formulation. It is noted that the release of TAS was slightly lower compared to TRA, which can be attributed to stability issues and limited solubility in the acidic environment.
When measuring the release from APS, it was observed that there was almost no release from the balls in the acidic environment, indicating that the coating layer was effective in preventing the entry of acidic ingredients into the balls for an extended period, thus avoiding unwanted release in the stomach. As the environment transitioned to a neutral pH (6.8), the outer layer began to dissolve, allowing for the release of APS.
These results confirm that the protective layer not only improves solubility characteristics but also helps to ensure the release of active materials in the targeted parts of the gastrointestinal tract, ultimately leading to improved drug efficacy and reduced potential side effects.
Therapeutic Efficacy of the Balls in Mouse Models
The impact of the balls on kidney fibrosis resulting from ureteral obstruction (UUO) was evaluated. Histological imaging of kidney slices stained with H&E showed significant differences between control mice and model mice. Experimental mice exhibited a clear pathological change in kidney tissue, showing an increase in interstitial area with infiltration of inflammatory cells. Although treatment with R&A and APSP alleviated the adverse effects, treatment using CP balls significantly contributed to the reduction of renal calcification and improved tissue health.
The analysis timing for collagen deposition in the tubular area showed that model mice had a high rate of collagen deposition, while treatment using CP balls resulted in a significant reduction in collagen-rich area. Additionally, the expression of genes related to kidney fibrosis was assessed, where the analysis showed strong variances in the gene expression of collagen I and fibronectin. Tissues that received CPs exhibited a significant decrease in the expression levels of these proteins, thereby negating excessive activation of fibroblast generation.
Effect of the Balls on Kidney Inflammation
Kidney inflammation plays a major role in the onset of kidney disease progression. Immune cells such as macrophages and T cells release inflammatory components that support fibrosis. The results showed a significant reduction in levels of inflammatory markers such as IL-6 and TNF-α after treating mice with CP balls, indicating that the treatment is not only effective against fibrosis but also helps in reducing the inflammatory response in damaged kidneys.
Moreover, treatment with CPs shows a positive effect on regulating the anti-inflammatory IL-10 level, which promotes healing by reducing inflammation-induced damage. These results support the importance of optimizing treatments targeting fibrosis and inflammation, providing a basis for future studies on the use of balls in addressing pathological conditions of kidney and gastrointestinal issues.
Improvement of Gut Microbiota via the Balls
To assess the impact of the balls on the gut microbiome, fecal samples from mice were analyzed using rDNA sequencing. The study showed that treatment with the balls did not significantly affect microbial genus diversity, but had a substantial impact on microbial composition, as the results showed a rebalancing of the microbial composition from the UUO model to a more normal composition post-treatment. This indicates that the balls work not only to enhance immune and inflammatory responses but also promote gastrointestinal health by modulating gut bacteria.
The effect
The relationship between the gut microbiota and overall health contributes to the enhancement of general well-being as an integrated component in treatment, indicating the close link between gut health and the body’s overall health. This provides a foundation for considering future treatments and utilizing targeted delivery techniques through healing drugs from various diseases.
Restoration of Gut Microbiome Composition in Mice After Ureteral Obstruction
Recent studies have shown the importance of gut microbiome composition in general health, especially after surgical procedures like unilateral ureteral obstruction (UUO).
