Mesh versus suspension surgery for vaginal prolapse
This trial compares two surgical options to treat a type of vaginal prolapse where the top of the vagina (apical area) has dropped. It may help find which approach works better and has fewer long-term problems for people who’ve had prior prolapse surgery and a hysterectomy.
HelsinkiAges 18–99 - NCT07466459Enrolling by invitation
Better dialysis for kids
This study looks at improving how well dialysis removes waste from the blood and uses water in children. It may help make treatments more effective and efficient.
GhentAges Up to 18 years - NCT06977867Enrolling by invitation
Stress balls for comfort and anxiety in dialysis
This study tests whether using a stress ball during hemodialysis (a treatment for kidney failure) helps patients feel more comfortable, less anxious, and more satisfied with their care.
Bitlis, TatvanAges 18–98 - NCT07426770Recruiting
Outpatient rehab vs. self-training for postpartum pelvic floor health
This trial compares two ways to help women recover from pelvic floor issues after childbirth: a structured outpatient rehab program vs. a self-training program at home. It aims to see which is better for treating and preventing problems like leakage or poor muscle tone.
VilniusAges 18–50 - NCT07001917Enrolling by invitation
MRI to check pancreas and kidney transplant health
This study uses MRI scans to see how well your new pancreas and kidney are working after transplant. It may help doctors monitor your transplant without needing risky procedures.
Wuhan, HubeiAges Any age - NCT04428554RecruitingPhase 2
Radiation to control bladder cancer spread after no growth
This trial tests whether giving focused radiation (SBRT) to a few remaining metastatic spots can stop bladder cancer from progressing after initial chemotherapy or immunotherapy has worked. It may help patients who still have up to three remaining distant lesions but are not getting worse.
AlbiAges 18 years+ - NCT07126119RecruitingPhase 2
Immunotherapy plus chemo before surgery for upper tract cancer
This trial tests whether combining the immunotherapy drug tislelizumab with the chemotherapy drug nab-paclitaxel before surgery can help treat high-risk upper tract urothelial cancer. The goal is to shrink the tumor and improve outcomes for patients who are planning to have their kidney and ureter removed.
Tianjin, Outside U.S.Ages 18 years+ - NCT05520151Recruiting
Oral immune-support before kidney or bladder surgery
This trial studies whether an oral immune-modulating product given before major bladder or kidney surgery can lower the risk of postoperative complications. If you’re scheduled for surgery like cystectomy or nephrectomy, it may be an option to help your recovery.
Aulnay-sous-BoisAges 18 years+ - NCT06454955RecruitingEarly Phase 1
PET scan imaging study for solid tumors using a new probe
This trial tests a new imaging agent that targets a protein called B7-H3 found on many solid tumors. It uses PET/CT to help doctors see and stage tumors more clearly.
Beijing, Beijing MunicipalityAges 18–75 - NCT07451106Recruiting
Wearable bladder sensor for pelvic health therapy
This trial tests whether a wearable sensor for the bladder can help guide pelvic health physical therapy. It is designed for people who are already referred to pelvic PT, including postpartum women and men who have had prostate surgery.
San Francisco, CaliforniaAges 18 years+ - NCT07416227Recruiting
Comparing two treatments for enlarged prostate
This trial compares two minimally invasive procedures for an enlarged prostate (benign prostatic hyperplasia). It tests whether water vapor thermal therapy or prostatic artery embolization works better to improve urinary symptoms.
Cairo, AbbassiaAges 50 years+ - NCT06041503RecruitingPhase 2
Treating rare bladder and testicular cancers with targeted therapy
This trial tests a combination of two drugs (enfortumab vedotin and pembrolizumab) for people with certain rare cancers of the urinary tract or testicles. The goal is to see if these treatments can shrink tumors or stop them from growing.
Bethesda, MarylandAges 18–120 - NCT07022236Recruiting
Thyroid Function in Hemodialysis Patients
This study checks thyroid function in people who are on long-term hemodialysis for kidney failure. It aims to see how common thyroid issues are in this group, which could help improve care.
SohagAges 13–80 - NCT07443280Recruiting
Gut health supplement study for dialysis patients
This trial tests whether a special blend of probiotics and prebiotics (called a synbiotic) can improve gut health and reduce harmful waste products in the blood for people on hemodialysis.
Taichung, Wuqi DistrictAges 18 years+ - NCT06984406Recruiting
Beet product for kidney protection during heart procedure
This trial tests a beet-derived food product (a natural source of nitrate) to see if it can help prevent kidney damage caused by the contrast dye used during a heart procedure called PCI. It is designed for people who already have a higher risk of this kidney problem.
MoscowAges 18 years+ - NCT07093866RecruitingPhase 2
Targeted drug combo for advanced prostate cancer
This trial tests a combination of two drugs—disitamab vedotin (a targeted antibody-drug that attacks HER2-positive cancer cells) and abiraterone (a hormone therapy)—to see if they can slow or shrink prostate cancer that has spread and become resistant to standard treatments.
Nanjing, JiangsuAges 18–75 - NCT06927635RecruitingPhase 2
SBRT vs standard care for prostate cancer that has spread to a few spots
This trial tests whether targeted radiation (SBRT) to a few sites of cancer spread can help men whose prostate cancer has stopped responding to hormone therapy but has not spread to many places. You may benefit if you have a limited number of growing spots outside the brain or spine.
Toronto, OntarioAges 18–100 - NCT06583590RecruitingPhase 2/Phase 3
Botulinum toxin plus daily tadalafil for erectile dysfunction
This trial tests if combining two treatments—a botulinum toxin injection and a daily oral medication (tadalafil)—can help men with diabetes-related erectile dysfunction who haven't responded well to standard pills. The goal is to see if this combination improves erections better than either treatment alone.
Aswān, Aswan GovernorateAges 21 years+ - NCT06777719RecruitingPhase 1
A study of immune cells to prevent kidney rejection
This trial tests if giving you back specially grown immune cells (called Tregs) made from your own blood can help your body accept a new kidney from a living donor with less rejection. It is for people who are ready for a first kidney transplant.
NantesAges 18–99 - NCT05125016RecruitingPhase 1/Phase 2
Study drug for advanced prostate cancer after standard treatments
This early-phase study tests whether REGN4336 is safe and how well it works, by itself or with REGN5678, in adults with advanced prostate cancer. It may help people whose cancer has continued to worsen despite standard prostate cancer medicines.
Palo Alto, CaliforniaAges 18 years+ - NCT07412470RecruitingPhase 2/Phase 3
Testing frexalimab vs tacrolimus for new kidney transplant patients
This trial compares a new drug called frexalimab to the standard drug tacrolimus in people who are getting their first kidney transplant. The goal is to see if frexalimab works better and has a safer side effect profile.
Boston, MassachusettsAges 18–70 - NCT07410988RecruitingPhase 4
Starch vs. crystalloid fluid for heart surgery patients
This trial compares two types of IV fluids (a starch solution vs. a balanced salt solution) to see which one better protects kidneys after heart surgery. It is for adults having planned heart surgery who do not have severe kidney problems.

Hefei, AnhuiAges 18–75 - NCT06585007RecruitingPhase 3
Radiation for limited cancer growth in castration-resistant prostate cancer
This trial tests whether giving focused radiation to limited areas of cancer growth (up to 3 spots) can help control the disease in men with castration-resistant prostate cancer. You may be eligible if your cancer is growing slowly and you are already on hormone therapy.
