This study looks at how deep endometriosis that affects the urinary tract (ureters and kidneys) impacts kidney function over time. It compares patients who had surgery for this condition at least two years ago with patients who are about to have surgery, to understand long-term kidney health.
PragueAges 18 years+ - NCT07782164Recruiting
Irreversible electroporation for recurrent pelvic tumors
This study tests a new technique called irreversible electroporation (IRE) for treating pelvic tumors that have returned despite earlier treatment. IRE uses electrical pulses to destroy cancer cells without surgery, offering a potential option when other local treatments like surgery or radiation are not suitable.

HIFU vs Robot Surgery for Localized Prostate Cancer
This trial compares two treatments for localized prostate cancer: high-intensity focused ultrasound (HIFU) using a device called Sonablate and robot-assisted surgery. It aims to see which works better and has fewer side effects.
Shanghai, Shanghai MunicipalityAges 40 years+ - NCT06447740Recruiting
Stent vs. medication for narrowed kidney artery
This trial compares placing a tiny mesh tube (stent) to open the narrowed kidney artery versus continuing blood pressure medicines alone. It is for people whose high blood pressure is hard to control even with multiple medications and who have a blockage in the kidney artery that can be treated.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05221021RecruitingPhase 4
Vaginal estrogen vs oral bladder medicine for overactive bladder
This study compares vaginal estradiol (a hormone placed in the vagina) versus an oral beta-3 medicine called mirabegron for overactive bladder symptoms. It looks to see which treatment works better and is safer for postmenopausal women.
Bethesda, MarylandAges 18 years+ - NCT06501222Recruiting
Remote ischemic preconditioning for kidney protection in CKD
This study tests whether a simple, non-invasive treatment called remote ischemic preconditioning (RIC) can help protect the kidneys of people with chronic kidney disease. RIC involves briefly restricting blood flow to one arm using a blood pressure cuff, which may trigger the body's own protective response.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06125405RecruitingPhase 3
Telitacicept for children with frequently relapsing nephrotic syndrome
This trial tests a new drug called telitacicept to help children whose nephrotic syndrome keeps coming back often or who need steroids to stay in remission. The goal is to see if it can keep urine protein levels low and reduce relapses.
Hangzhou, ZhejiangAges 2–18 - NCT06564415Recruiting
Laser treatment registry for enlarged prostate symptoms
This study is a European registry tracking how a laser treatment (TPLA) helps men with an enlarged prostate and bothersome urinary symptoms. It aims to see how safe and effective this new procedure is for daily life.
FlorenceAges 18 years+ - NCT06493526RecruitingPhase 4
Mycophenolate therapy for kidney transplant patients with no DQ mismatch
This trial tests a mycophenolate-based therapy for kidney transplant recipients who have no HLA-DQ mismatch. If you had your first kidney transplant 3-12 months ago without DQ mismatch and are on standard immunosuppressants, you may qualify.
Edegem, AntwerpAges 18 years+ - NCT06544473RecruitingPhase 4
Estrogen pill vs. patch for Turner syndrome
This trial compares oral and transdermal (patch) estrogen to find the right dose for women with Turner syndrome. It aims to see which method works best for hormone replacement.
Aarhus, Aarhus NAges 18–50 - NCT07770802RecruitingPhase 1
Study of an investigational cell therapy for advanced kidney cancer
This trial tests an investigational medicine called HS-IT101 for people with advanced kidney cancer that hasn't responded to standard treatments. The goal is to see if this new therapy can help shrink or control the cancer.
BeijingAges 18–75 - NCT07767773Recruiting
Long-term safety of two kidney stone scope methods
This study is checking the long-term safety of two different ways of doing a kidney stone scope procedure (one uses a small tube to guide the scope, the other does not). If you had this procedure for a kidney stone (up to 20 mm) and it's been at least a year, they want to follow up with you to see how you're doing.
CairoAges 18 years+ - NCT07773090Recruiting
Stenting before mini-keyhole kidney stone surgery
This trial is looking at whether placing a small tube (stent) in the ureter before a type of keyhole surgery for kidney stones helps with outcomes like pain and success of the procedure. It aims to see if this pre-treatment makes the surgery easier, potentially reducing complications and improving stone removal.
CairoAges 18–70 - NCT07768865Recruiting
Artery stiffness in young people with kidney disease
This study looks at how stiff the arteries are in children and young adults with chronic kidney disease (CKD) compared to healthy controls. The results may help doctors better understand heart risks and improve care for young people with kidney problems.
London, Greater LondonAges 10–25 - NCT07772752Recruiting
Urinary crystals study: antibiotics and kidney effects
This study looks at whether certain strong antibiotics can cause crystals in urine that might damage kidneys. It's for adults taking specific antibiotics at high doses.
BrusselsAges 18 years+ - NCT07767500Recruiting
MRI-guided radiation therapy for early-stage kidney cancer
This trial tests a new way to deliver radiation to kidney tumors using MRI guidance. It aims to treat early-stage kidney cancer while sparing healthy tissue, and may be an option for people who cannot have surgery or prefer not to.
New York, New YorkAges 18 years+ - NCT07773103Recruiting
Tadalafil and blood vessel markers for erectile dysfunction
This study tests whether tadalafil, a daily pill for erectile dysfunction, improves blood vessel health and erectile function. It may help men with erectile dysfunction caused by blood vessel problems.
CairoAges 30–70 - NCT07773051Recruiting
Synthetic vascular graft for dialysis access
This trial tests a new synthetic blood vessel graft that connects an artery to a vein in your arm to create a reliable spot for dialysis. It's for people with kidney failure who need long-term dialysis but can't have the usual fistula made from their own blood vessels.

Hong KongAges 18 years+ - NCT06548529Recruiting
HER2 PET/CT scan to predict treatment response in bladder cancer
This trial uses a special PET/CT scan to see if your bladder cancer has HER2 proteins, which can help predict how well you will respond to a targeted antibody-drug conjugate treatment. It is for people with advanced bladder cancer who have already tried certain standard therapies.
BeijingAges 18–80 - NCT06325995Recruiting
Short radiation course after prostate surgery for rising PSA
This trial tests a shorter, stronger course of radiation (hypofractionated radiotherapy) given after prostate removal surgery. It may help people whose PSA levels rise again after surgery, aiming to reduce side effects and improve outcomes.
