Robot surgery for one-sided prostate cancer with urethra preserved
This study looks at a robotic prostate operation that aims to remove only the affected side while keeping the urethra (the tube for urination) to help preserve urinary function. It’s for people with low- to intermediate-risk, one-sided prostate cancer and no spread to lymph nodes, bones, or other organs.

Alvimopan vs placebo to reduce bowel slowdown after bladder surgery
This trial tests whether alvimopan, a medicine given around the time of bladder removal surgery, can help your bowels start working sooner after surgery compared with a placebo (inactive pill). It may help shorten recovery by reducing bowel-related side effects on an enhanced recovery plan.
Boston, MassachusettsAges 18–85 - NCT06065852Recruiting
National registry for rare kidney diseases
This study creates a registry to collect health information from people with rare kidney diseases. It aims to improve understanding and future treatments by tracking patient experiences.
Bristol, South WestAges Any age - NCT06065982Recruiting
Study of a method for placing a dialysis catheter (PREDICT)
This study watches how well a certain method (percutaneous) works for placing a peritoneal dialysis (PD) catheter, which is a soft tube used for a type of kidney dialysis. By tracking patients’ experiences before and after the procedure, the study aims to improve care for people with kidney failure.
BrusselsAges 18 years+ - NCT06067867Recruiting
Kidney and pregnancy registry study
This study tracks the health of women with kidney problems before, during, and after pregnancy to learn how to better care for them. It is for women who have had kidney disease, high blood pressure, certain pregnancy complications, or a kidney transplant.
BrusselsAges 18 years+ - NCT06079788RecruitingPhase 3
ACTH for children with frequently relapsing nephrotic syndrome
This trial tests if a hormone called ACTH can help children with nephrotic syndrome who have frequent relapses or need steroids to stay in remission. It aims to find a treatment that may reduce the need for steroids and prevent relapses.
Wuhan, HubeiAges 2–14 - NCT04954690Recruiting
Exercise program after kidney transplant for older adults
This trial tests a structured, coached exercise program for people who recently received a living-donor kidney and are coming from dialysis. It may help improve strength and daily function after transplant, especially if starting fitness is difficult.
San Francisco, CaliforniaAges 50 years+ - NCT03034187Recruiting
Track side effects after prostate cancer radiation
This study follows people with prostate cancer who receive radiation to understand what side effects and quality-of-life changes happen over time. It may help improve standard follow-up care by better tracking radiation-related toxicity.
GroningenAges 18 years+ - NCT06026436Recruiting
Predicting clot and bleeding risk in kidney disease patients after a heart attack
This trial tests whether a blood test looking at platelets and tiny cell particles can help predict future blood clots or bleeding in people who have both chronic kidney disease and a recent heart attack. The goal is to improve treatment safety.
MarseilleAges 18–90 - NCT06116019Recruiting
Online adaptive radiotherapy for cancer patients
This trial tests a new radiation therapy machine that adjusts the radiation plan in real-time based on changes in your body. It may help make treatment more precise and reduce side effects.
BerlinAges 18 years+ - NCT06120387Recruiting
Radiation after kidney-sparing surgery for high-risk ureteral cancer
This trial tests whether adding radiation therapy after surgery that removes only part of the ureter or the entire kidney and ureter helps prevent cancer from coming back in patients who have high-risk features like aggressive cell type or deep tumor invasion.
BeijingAges 18 years+ - NCT05786768RecruitingPhase 2/Phase 3
Obinutuzumab vs rituximab for relapsing childhood kidney syndrome
This study compares two antibody medicines, obinutuzumab and rituximab, to prevent relapses of steroid-dependent or frequently relapsing nephrotic syndrome in children. It looks at whether one option works better and is safer, including infection risk.
ParisAges 3–18 - NCT05527626Recruiting
Study of daily life in people with advanced kidney disease
This study looks at real-world information about people living with advanced chronic kidney disease. Your participation mainly involves allowing researchers to use your existing medical data to understand care and outcomes.
StrasbourgAges 18 years+ - NCT05781217RecruitingPhase 3
Short vs longer hormone therapy after salvage prostate radiation
This trial compares two lengths of hormone treatment (androgen deprivation therapy) given around “salvage” radiation after prostate surgery for rising PSA. It aims to see which schedule works best to control prostate cancer while keeping side effects manageable.
L'Hospitalet de Llobregat, BarcelonaAges 18 years+ - NCT06138080Recruiting
Comparing two imaging tests for reflux in children with UTIs
This study compares two types of imaging tests—a special ultrasound and a nuclear medicine scan—to see which is better at finding reflux (backward flow of urine) in young children who have had repeated UTIs. The goal is to find a safer, more accurate way to diagnose the condition.
TurkuAges birth–6 years - NCT05600634Recruiting
Monitoring skin graft to spot rejection after kidney transplant
This study follows people after a kidney transplant to see if a small skin graft can help detect early signs of acute rejection. It may help your care team notice rejection sooner and adjust treatment earlier.
Xi'an, ShannxiAges 18–60 - NCT06147349Recruiting
Kidney cancer observation study
This study follows people with kidney cancer who are scheduled for surgery to remove their tumor. It aims to learn more about the disease and how it behaves over time.
Milan, MIAges 18 years+ - NCT03185702Recruiting
Turner syndrome research registry for people with Turner syndrome
This registry study is collecting information from people who have Turner syndrome. It may help researchers better understand the condition and plan future studies that could lead to improved care.
Houston, TexasAges Any age - NCT05767307Recruiting
MRI for suspected prostate cancer in Denmark
This study is enrolling adults who have prostate cancer concerns and are being sent for an MRI scan. It aims to improve evaluation of suspected prostate cancer, which may help doctors decide next steps more accurately.
Aarhus N, AarhusAges 18–99 - NCT06167629Recruiting
PSMA PET scan study for prostate cancer
This study uses a special type of PET scan called PSMA PET to better understand and track prostate cancer. The scan helps doctors see where the cancer is in the body and if treatment is working.
MilanAges 18 years+ - NCT03083184RecruitingPhase 3
Ethanol lock solution to prevent catheter infections
This Phase 3 study tests whether a medicine-filled “lock” put into a dialysis catheter can lower the risk of infections. It is meant for people on regular dialysis with a tunnelled catheter who already have it in place.
Clermont-FerrandAges 18 years+ - NCT06162546Recruiting
Registry for resistant nephrotic syndrome in children
