Nephrogenic diabetes insipidus

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 early-stage study is testing a single dose of the drug MK-2828 in 24 people with different levels of kidney function, including those with severe kidney failure or on dialysis. The goal is to measure how the drug moves through the body over time and compare it to healthy vol…

This study looks at how the medicine PF-07328948 moves through the body in adults with different levels of kidney function. About 28 people aged 18 to 80, with either normal kidneys or moderate-to-severe kidney problems, will take a single tablet. Researchers will check safety an…

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 will enroll 5,000 adults with kidney disease or at risk for it, including transplant recipients. Researchers will analyze blood and urine samples to find molecular patterns that predict disease progression, complications, or treatment response. The goal is to improve r…

This early-stage study tests how a single dose of the diabetes drug GL0034 behaves in people with different levels of kidney function. About 40 adults with type 2 diabetes will be grouped by kidney health, from normal to severe impairment. Researchers will measure drug levels in …

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 is for adults who have had a liver transplant and now have kidney issues. Researchers want to learn how often kidney function gets worse and what factors might cause that decline. They will look at results from kidney biopsies already done in the past 3 months. The goa…

This early-stage study tests a single dose of the drug GZR18 in 32 adults who are overweight or obese, some with mild to severe kidney problems and some with normal kidneys. Researchers want to see how kidney function affects drug levels and safety. The goal is to find the right …

This study follows 100 women who had preeclampsia, HELLP syndrome, or kidney problems during pregnancy. Researchers will measure blood vessel stiffness and collect blood samples for a biobank. The goal is to better understand long-term heart and kidney health after these conditio…
