This study tests whether a 12-week course of a multi-species synbiotic supplement can lower harmful gut toxins and reduce inflammation in adults on hemodialysis. About 30 participants will take the supplement and have their blood and urine levels of toxins and inflammatory marker…

This study is testing whether a 12-week course of a multi-species synbiotic (a mix of probiotics and prebiotics) can improve gut health and reduce harmful toxins in the blood of people on hemodialysis. The trial will enroll 30 adults who have been on dialysis for at least 3 month…

This trial tests a device called JuxtaFlow that applies mild suction to the kidneys during heart surgery. The goal is to see if it can protect kidney function in people with pre-existing kidney problems. 124 adults undergoing heart surgery with a heart-lung machine will be random…

This study tests whether special filters (sorption technologies) can lower inflammation in people on long-term hemodialysis for kidney failure. About 60 adults with high inflammation levels will receive the filter during their regular dialysis sessions. The main goal is to see if…

This study compares two types of ultrasound-guided nerve blocks for pain control after open kidney removal surgery. Ninety adults will receive either a rhomboid intercostal sub-serratus plane block or an external oblique intercostal block. Researchers will measure how long it tak…

This study looks at whether adding a blood-filtering step called hemoadsorption to regular dialysis can help people with kidney failure who still have bothersome symptoms like itching, tiredness, and trouble sleeping. Researchers will follow 120 adults for 6 months, tracking how …

This study looks at whether dipyridamole, a drug usually used for heart conditions, can reduce the uncomfortable urge to move the legs in people with kidney failure who are on dialysis. About 80 adults will take the drug three times a day for 12 weeks. Researchers will measure ch…

This study tests whether letting a bladder catheter fall out on its own (passive removal) is better than having a nurse pull it out (active removal) after urological surgery. 160 men will be randomly assigned to one method. Researchers will measure satisfaction, pain, and anxiety…

This study looks at how a new cholesterol-lowering tablet, HRS-1301, behaves in people with mild, moderate, or severe kidney problems compared to healthy volunteers. The goal is to understand if kidney function changes how the drug works, so doctors can give the right dose. About…

This study tests a single dose of hydroxynidone capsules in 56 people with different levels of kidney function and healthy volunteers. The goal is to see how the drug moves through the body and if it is safe in people with kidney problems. Participants will have blood and urine t…

This study is for older adults, including those in the hospital or with low priority care needs. Researchers want to see if newer methods, like body scans and blood tests, can better detect malnutrition and kidney problems than current standard tests. The goal is to make diagnosi…

This study tests a new method to help patients understand complex spine or prostate surgeries before they agree to them. Instead of just reading a form, patients watch multimedia content and answer questions to check their understanding. The goal is to see if this approach makes …

This study looks at how well three AI models—ChatGPT, Gemini, and Deepseek—can diagnose and suggest treatments for urology diseases. Researchers will use 800 past patient records from four hospitals to check the AI's accuracy and usefulness. The goal is to understand if AI can he…

This study reviews medical records from over 50,000 critically ill patients to see if starting dialysis earlier helps them live longer. Researchers will compare patients who started dialysis early versus late, looking at survival up to 90 days and beyond. The goal is to find the …
