Investigational drug plus lenvatinib for penile cancer that has been treated before
This trial tests a combination of two drugs, QL1706 and lenvatinib, in people with penile cancer that has already been treated with other therapies. The goal is to see if this new combination can shrink tumors or slow cancer growth.
Guangzhou, GuangdongAges 18–80 - NCT07379814Recruiting
New muscle surgery for urinary retention
This trial tests a surgery that uses a muscle from your belly to help your bladder empty. It may be an option if you have trouble urinating because your bladder muscle is too weak to contract.

IV vitamin C plus chemo for bladder cancer
This trial tests adding high-dose vitamin C (ascorbate) to a standard chemotherapy combination for people with muscle-invasive bladder cancer who cannot take or choose not to take cisplatin. The goal is to find a more affordable and effective treatment option.
Iowa City, IowaAges 18 years+ - NCT06836206RecruitingPhase 1/Phase 2
Gum arabic and kidney function in dialysis patients
This trial tests if taking gum arabic, a natural fiber, can help preserve the remaining kidney function in adults on dialysis. If you produce at least 200 ml of urine a day, this study might help you learn about a possible way to protect your kidneys.
Abu DhabiAges 18 years+ - NCT05000827Recruiting
PSMA PET scan to guide lymph node surgery in prostatectomy
This study tests whether a special prostate scan called PSMA PET/CT can help doctors decide which pelvic lymph nodes to remove during prostate surgery. It may improve who needs lymph node surgery by using scan results to guide the operation.
Nijmegen, GelderlandAges 18 years+ - NCT06402851RecruitingPhase 4
Blood thinner or none for atrial fibrillation with dialysis
This trial compares two types of blood thinners (vitamin K antagonists and factor Xa inhibitors) versus no blood thinner in people with atrial fibrillation who are on dialysis or have very advanced kidney disease. It aims to see which option is safest and most effective for preventing strokes and bleeds.
Salvador, Estado de BahiaAges 18 years+ - NCT06839768Recruiting
Comparing two procedures for enlarged prostate symptoms
This study compares a new, less invasive laser procedure (MILEP) with the standard surgery (EEP) for treating bothersome urinary symptoms caused by an enlarged prostate. It aims to see if the new approach is just as safe and effective.
MoscowAges 18–85 - NCT06839040Recruiting
Exercise and education program to reduce falls and urine leakage
This study tests a program of exercises and education to help older women reduce their risk of falling and improve bladder control. If you are a woman aged 60–80 with urine leakage and do little exercise, this program might support your strength and confidence.
Valencia, ValenciaAges 60–80 - NCT06799832Recruiting
Guiding fluid management during major abdominal surgery using a new index
This study tests whether a new tool, the urethral perfusion index, can help doctors better manage fluids during and after major abdominal surgery. It uses standard catheters already in place, so there's no extra device needed.
HamburgAges 45 years+ - NCT06818682RecruitingPhase 2
Shortened hormone therapy with radiation for high-risk prostate cancer
This trial tests whether a shorter course of hormone therapy (2 years) plus a new hormone drug (6 months) with radiation is as effective as longer treatment for high-risk prostate cancer that hasn't spread.
Mumbai, MaharashtraAges 19–99 - NCT07371000Recruiting
Early detection of overactive bladder to improve quality of life
This study aims to find people with overactive bladder (OAB) early on, before it seriously affects their daily life. If you often need to urinate more than 7 times in 24 hours, you may be able to join and help researchers learn how to reduce the negative impact of these symptoms.
BrnoAges 18 years+ - NCT05231655Recruiting
Study testing fresh tumor tissue from cancer surgery or biopsy
This study collects fresh samples of tumor tissue during procedures like surgery, biopsy, or TURBT to test a cancer therapy outside the body. It may help researchers learn which treatments work better for different solid cancers.
Sheffield, South YorkshireAges 16 years+ - NCT06316778Recruiting
Pelvic floor training for women with myotonic dystrophy
This study tests whether pelvic floor muscle training (exercises to strengthen the muscles that control urine flow) can help women with myotonic dystrophy type 1 who have bladder leakage. It's a gentle, non-surgical approach that may improve quality of life.
Jonquière, QuebecAges 18 years+ - NCT07378670Recruiting
Surgery for penile cancer: comparing two groin lymph node removal approaches
This study compares two ways of removing lymph nodes in the groin to treat or prevent the spread of penile cancer. It looks at which surgery might be safer and more effective for patients with early to moderate stage disease.
BerlinAges 18 years+ - NCT07379281Recruiting
Personalized chemo testing for bladder cancer
This trial tests whether using a patient's own tumor cells grown in a lab (organoids) can help doctors choose the best chemotherapy drugs before bladder cancer surgery. It may help find the most effective treatment for you.
JinanAges 18–80 - NCT07377929Recruiting
Botox with prostate surgery for urinary symptoms
This trial tests whether adding Botox to standard prostate surgery (TURP or Aquablation) can better improve urinary symptoms in men. It is for men who are already planning to have both procedures.
Seattle, WashingtonAges 18 years+ - NCT07378358Recruiting
AI for urology diagnosis and treatment
This study is testing how well AI can help with diagnosis and treatment by looking at medical records of patients from four hospitals, specifically those with urological conditions. It's a way to see if AI can improve care without needing any new tests or visits.
FuzhouAges 18 years+ - NCT07377006Recruiting
Genetic testing decision support for prostate cancer
This study tests a tool to help prostate cancer patients understand and decide about genetic testing. It is designed for patients at LBJ Hospital who have been recommended for testing by their doctor.
Houston, TexasAges 18 years+ - NCT07379255Recruiting
Organoid test to guide chemo after bladder cancer surgery
This trial uses a lab-grown version of your tumor (an organoid) to see which chemotherapy might work best for you after bladder cancer surgery. It helps doctors choose the most effective treatment for each person.
Jinan, ShandongAges 18–80 - NCT07372547Recruiting
Does Shower Standing Help Women Empty Bladder After Catheter Removal?
This trial compares standing in the shower versus sitting on a toilet to see which position helps women empty their bladder more completely after a urinary catheter is removed following vaginal surgery.
AshdodAges 18–99 - NCT07374042RecruitingPhase 3
A supplement to protect muscle in advanced kidney disease
This trial tests whether a special diet supplement (Ketoanalogue) can help protect your muscles while you follow a moderate protein diet. It is for people with chronic kidney disease stage 4 or 5 who are not on dialysis or have not had a kidney transplant.
Clermont-FerrandAges 18–100 - NCT07379268Recruiting
Anti-HER2 drug for advanced bladder cancer
