Medicines for catheter discomfort after bladder or prostate surgery
This study tests whether two medicines, dexmedetomidine and esketamine, can reduce discomfort from a urinary catheter after bladder or prostate surgery. If you are having this type of surgery and need a catheter, this trial may help find a better way to manage that discomfort.

Lu-177 treatment for PSMA-positive metastatic prostate cancer
This trial tests a radioactive drug called Lutetium-177 (Lu-177) that targets and kills prostate cancer cells showing a specific marker (PSMA). It's for men with advanced prostate cancer that has spread and stopped responding to hormone therapy, and who have already tried certain chemotherapy or cannot have it.

Higher dose radiation with hormone therapy for high-risk prostate cancer
This trial tests a higher dose of radiation given in fewer sessions (hypofractionated) combined with hormone therapy for men with high-risk prostate cancer that has not spread. A gel spacer called SpaceOAR is used to protect the rectum. The goal is to see if this approach is safe and effective.
SeoulAges 20 years+ - NCT06446648RecruitingEarly Phase 1
Green dye to improve recovery after prostate cancer surgery
This trial tests whether using a green dye (ICG) during robot-assisted prostate removal helps preserve urinary and sexual function. It is for men with localized prostate cancer and good baseline erectile function.
Orange, CaliforniaAges 18 years+ - NCT06373055Recruiting
Predicting chemo response in bladder cancer with gene mapping
This trial uses a new technology called spatial transcriptomics to study how bladder cancer tumors respond to chemotherapy before surgery. It aims to find patterns that predict which patients will benefit from treatment.
SeoulAges 18–80 - NCT06378242RecruitingPhase 1/Phase 2
Testing a bladder cancer drug for high-risk NMIBC patients
This trial tests a drug called Disitamab Vedotin, given directly into the bladder, for a type of early bladder cancer (high-risk NMIBC) that has a protein called HER2. It aims to see if this treatment can help avoid more radical surgery.
Guangzhou, GuangdongAges 18–75 - NCT06445647Recruiting
Core exercise for daily activities in hemodialysis patients
This study tests whether doing core-strengthening exercises can help people on hemodialysis with daily activities like walking, bathing, and dressing. If you are between 55 and 70, have been on dialysis for at least 6 months, and are generally healthy enough to exercise, you may be able to join.
CairoAges 55–70 - NCT06317623Recruiting
Urinary tract dilation before and after birth
This study follows pregnant women and their babies who have been diagnosed with a widening of the urinary tract before birth. It aims to learn how these changes progress during pregnancy and after birth, and to ensure proper follow-up care for the baby.
ZáborskéAges 18–50 - NCT06235892RecruitingPhase 3
Lowering Tacrolimus for Low-Risk Kidney Transplant Patients
This trial tests whether safely lowering the dose of tacrolimus—an anti-rejection drug—can still protect a kidney transplant one year after surgery. It's for first-time transplant recipients with low immune risk.
NantesAges 18 years+ - NCT06274333RecruitingPhase 3
Easing bladder discomfort after kidney stone surgery
This trial tests if adding dexmedetomidine or tramadol to standard paracetamol can reduce bladder pain and discomfort from the urinary catheter used during kidney stone removal. It may help patients feel more comfortable after their procedure.
Cairo, Cairo GovernorateAges 20–50 - NCT06325774Recruiting
Shorter radiation for localized prostate cancer
This trial tests a shorter, more intense course of radiation (hypofractionated radiotherapy) for men with localized prostate cancer that hasn't spread. It aims to see if this treatment is safe and effective and may reduce the number of hospital visits.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06209736RecruitingPhase 2
Study of OMS906 for C3G and ICGN kidney diseases
This study tests an experimental drug called OMS906 for people with C3G or ICGN (immune-related kidney diseases). It aims to see if the drug is safe and can reduce kidney damage. You may qualify if you have a confirmed diagnosis, high protein in your urine, and stable kidney function.
KaunasAges 18–99 - NCT06225726Recruiting
Bladder tumor stiffness study with ultrasound
This trial uses a special ultrasound technique to measure the stiffness of bladder tumors. It may help doctors understand tumors better before surgery.
ToursAges 18 years+ - NCT06300788Recruiting
Pyrophosphate study in children with kidney disease
This study looks at a natural chemical in the body called pyrophosphate (PPi) in children with chronic kidney disease. It aims to understand how kidney problems affect this chemical, which is important for bone health. The study needs kids with different kidney stages, including those on dialysis, with a transplant, or even healthy kids having surgery for comparison.
Nice, Alpes-MaritimesAges birth–18 years - NCT06289270Recruiting
Bladder cancer and urine bacteria study
This study looks at bacteria in urine and the bladder to understand if they play a role in causing bladder cancer. Researchers will compare samples from men with bladder cancer and healthy controls.
Cairo, Giza GovernorateAges 18 years+ - NCT06305390RecruitingPhase 2
PSMA PET/MRI for prostate cancer diagnosis
This trial tests a new, all-in-one PET/MRI scan to see if it can better find aggressive prostate cancer in men who need a biopsy. It may help avoid unnecessary biopsies and give a clearer picture of your condition.
Milan, MilanoAges 18 years+ - NCT06184464Recruiting
Shrinking the prostate before radiation for prostate cancer
This trial tests how well the hormone drug leuprorelin acetate shrinks the prostate before radiation therapy for men with prostate cancer. The goal is to make radiation safer and more effective.
Terrassa, BarcelonaAges 18–95 - NCT06200987Recruiting
Penile vibrator to prevent sexual and bladder problems after prostate surgery
This trial tests whether using a penile vibrator before and after prostate cancer surgery can help preserve sexual function and bladder control. It is for men who are having nerve-sparing prostatectomy and have good erections and bladder control before surgery.
HerlevAges 18 years+ - NCT06268769RecruitingPhase 4
Comparing two tacrolimus drugs in kidney transplant patients
This study compares two long-acting forms of tacrolimus (Envarsus and Advagraf) to see how the body processes them after a kidney transplant. It aims to find the best way to use these medications to prevent organ rejection.
AachenAges 18 years+ - NCT06286098Enrolling by invitationPhase 3
Alpha lipoic acid for kids on dialysis
This trial tests if alpha lipoic acid, a common supplement, can help reduce stress on the body for children who are on regular hemodialysis. It may offer a way to support their health during treatment.
Cairo, El WeiliAges 8–16 - NCT06265519Recruiting
Urine markers for enlarged prostate check
This study looks at two natural substances in urine (BDNF and NGF) to see if they can help doctors understand how the lower urinary tract is working in men with an enlarged prostate. It is a simple, non-invasive test that may lead to better ways to diagnose and treat bladder problems.
IstanbulAges 50–80 - NCT06205576Recruiting
Balloon treatment for narrowed AV fistula veins
This trial tests a balloon device to open up narrowed veins in an AV fistula used for dialysis. It may help if your fistula has a blockage that causes problems like high pressure or low blood flow.
BeijingAges 18–85 - NCT06201078RecruitingPhase 2
Second radiation for prostate cancer that returns locally
This trial tests a second round of precise, high-dose radiation (stereotactic body radiotherapy) for men whose prostate cancer has come back only in the prostate after their first radiation treatment. It aims to control the recurrence with fewer side effects.
