This study tests whether a carefully controlled low protein diet (about 0.6 grams of protein per kilogram of body weight each day) can help people with advanced chronic kidney disease delay the need for dialysis or a kidney transplant. The study enrolls adults with stage 4-5 or f…

This study tests whether giving two common drugs, tranexamic acid and desmopressin, before surgery can reduce bleeding in patients with chronic kidney disease or acute kidney injury. About 100 adults having noncardiac surgery will be randomly assigned to receive one or both drugs…

This study looks at whether lowering high parathyroid hormone levels can help protect bone density in people with advanced chronic kidney disease. About 70 adults aged 50 and older with kidney failure not on dialysis will be assigned to different treatment targets for their hormo…

This study tests whether canagliflozin, a drug used for diabetes, can improve heart structure in people with advanced kidney disease (stage 4 or 5) or on dialysis. About 92 participants will receive either the drug or a placebo for 12 months, with heart changes measured by MRI. T…

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 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 well the immune system works in people with end-stage kidney disease. Researchers will take blood samples from 100 patients and healthy donors to study T-cells, a key part of the immune system. They also plan to test a lab technique to restore T-cell funct…

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 looks at how the body handles a new drug called S-892216 in people with mild, moderate, or severe kidney problems, including those on dialysis, compared to people with healthy kidneys. About 40 adults will take a single dose of the drug, and researchers will measure it…
