Relaxin Agonist to Protect Kidneys During Heart Surgery
This study tests whether a drug called R2R01 can help protect your kidneys during major heart surgery. Heart surgery can sometimes damage the kidneys, and this trial is looking to see if this new medication reduces that risk.

Balcinrenone and Dapagliflozin for Moderate-to-Severe Kidney Disease
This study tests a combination of two medications (balcinrenone and dapagliflozin) to help protect your kidneys if you have moderate-to-severe chronic kidney disease. The trial evaluates whether this combination slows kidney damage and improves kidney health.

Istanbul, IstanbulAges 18 years+ - NCT05344573Recruiting
Testing better blood-flow rhythms during heart bypass surgery
This trial studies ways to control the “pulsatility” (how the blood pressure pulses during circulation) while you are on a heart-lung bypass machine. It may help improve safety and heart function during planned heart surgery.
Aurora, ColoradoAges 50–70 - NCT07624019Recruiting
Kidney stiffness imaging to predict surgery success in children
This study tests whether a special ultrasound scan that measures kidney stiffness can predict how well a child's kidney will work after surgery to fix a ureter blockage. The goal is to help doctors know which children might recover better kidney function after the procedure.
Banī Suwayf, Beni Suweif GovernorateAges 6 months–18 years - NCT07626151Recruiting
Fluid Management During Robotic Prostate Surgery
This trial compares two approaches to giving IV fluids during robotic prostate removal surgery. Researchers will use a heart-monitoring device to guide one approach and want to see which method works better for patient recovery.

Kidney Stone Blockage: Best Drainage Method Before Removal
This study compares two ways to drain urine when a kidney stone completely blocks the ureter (the tube from kidney to bladder) in patients with only one working kidney. After your kidney recovers, doctors will remove the stone using a minimally invasive camera procedure.
Banī Suwayf, Beni Suweif GovernorateAges 18 years+ - NCT07627438Recruiting
Pelvic Floor Exercises for Premature Ejaculation
This trial tests whether targeted pelvic floor muscle exercises can help men with lifelong premature ejaculation last longer during intercourse. The study focuses on strengthening the muscles that control ejaculation through physical therapy techniques.
Tanta, TantaAges 18–50 - NCT07626710Recruiting
How Heart Valve Replacement Affects Kidney Function
This study looks at whether a minimally invasive heart valve procedure (TAVI) affects how well your kidneys work. Researchers will track your kidney function before and after the procedure using blood tests to understand any changes.
Roma, RMAges 18 years+ - NCT07621692RecruitingPhase 1
New radioactive therapy for advanced prostate cancer
This is an early-stage trial testing a new radioactive treatment (161Tb-PSMA) for men with advanced prostate cancer that has spread and stopped responding to hormone therapy. The treatment targets cancer cells using a radioactive metal that may be more effective than older similar treatments.
TaipeiAges 20 years+ - NCT07623980Recruiting
Laser Treatments for Childhood Bladder Stones
This trial compares two laser methods to break up bladder stones in children. Both approaches use a thin camera inserted through the urethra (the tube that carries urine), and the study aims to find which method works better and causes fewer complications.
Banī Suwayf, Beni Suweif GovernorateAges Up to 18 years - NCT07627828Recruiting
ComfiJ versus standard stent for kidney stone recovery
This trial compares two types of temporary drainage tubes (stents) placed in the ureter—the tube that carries urine from kidney to bladder—after surgery to remove kidney or ureteral stones. The study measures which stent causes fewer uncomfortable symptoms during the 2-week recovery period.
Banī Suwayf, Beni Suweif GovernorateAges 18 years+ - NCT07628322Recruiting
Exercise methods for postpartum urine leakage
This study compares two types of exercises designed to help women who leak urine after vaginal delivery. The goal is to see which approach works better at reducing or stopping leakage.
Sargodha, Punjab ProvinceAges 25–40 - NCT07626086Recruiting
Pilates exercises to improve balance and quality of life after kidney transplant
This study tests whether pilates exercises can help kidney transplant patients improve their balance, reduce fatigue, and feel better overall. You would do pilates workouts over several weeks while researchers track how you feel and function.
Damanhur, BeheiraAges 20–50 - NCT07623876RecruitingPhase 2
Medications to ease kidney stone surgery access
This trial tests whether two common medications—tamsulosin and aminophylline—help surgeons access kidney stones more easily during a minimally invasive procedure called retrograde intrarenal surgery (RIRS). The goal is to make the surgery smoother and potentially reduce complications.
Aswān, Aswan GovernorateAges 18 years+ - NCT07623941Recruiting
Focal Therapy Registry for Localized Prostate Cancer
This registry tracks men with early-stage prostate cancer who choose focal therapy—a targeted treatment that destroys only the cancer area while preserving healthy prostate tissue. The study helps doctors understand how well this approach works and its safety.
New York, New YorkAges 40–85 - NCT07620873Recruiting
Virtual Reality Education Before Kidney Stone Surgery
This study tests whether using virtual reality to learn about your upcoming kidney stone surgery can reduce anxiety and help you feel more prepared. You'll use a VR headset before your procedure to see what to expect.
KeelungAges 18 years+ - NCT07627178Recruiting
Comparing laser treatments for enlarged prostate
This study compares three different surgical laser techniques to treat benign prostate enlargement (BPH) that causes severe urinary symptoms and hasn't improved with medication. The goal is to find which method is safest and works best for large prostates.
Tanta, Gharbia GovernorateAges Any age - NCT06062875RecruitingPhase 2
Testing a drug for enlarged prostate symptoms
This trial tests whether a drug called adalimumab (a TNF blocker) can improve symptoms of an enlarged prostate. It is for men aged 45-80 with a large prostate and bothersome urinary symptoms who have not used this type of medication before.
Glenview, IllinoisAges 45–80 - NCT05791162Recruiting

Can an anti-inflammatory drug prevent urethral stricture recurrence?
This trial tests if taking a COX-2 inhibitor (a type of anti-inflammatory) after a procedure to widen a narrowed urethra can lower the chances of the narrowing coming back. It may help men with a short first-time stricture.
New Valley, New Valley GovernorateAges 18 years+ - NCT04794582Recruiting

This trial looks at ways to prevent an incisional hernia (a bulge at the surgical scar) after your first kidney transplant. If you’re getting a first transplant, joining could help test treatments or strategies that lower this post-surgery complication.
MadridAges 18 years+ - NCT06374121Recruiting
Kidney preservation with or without machine perfusion
This study compares two ways of preserving kidneys from older or less healthy donors before transplant – one using a machine that pumps fluid through the kidney, and one without. It may help improve how well these kidneys work after transplant.
