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 - 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.

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.
MilanAges 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.
CairoAges 40–80 - 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+ - 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 - 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 - 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+ - NCT07627880Recruiting
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+ - 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 - NCT07629479Recruiting
Prostate Surgery Comparing Two Methods to Preserve Ejaculation
This trial tests two surgical approaches for enlarged prostate—one specifically designed to preserve the ability to ejaculate and a standard approach—in men with urinary symptoms who haven't improved with medication. You'll be asked about sexual and urinary function before and after surgery.
Banī Suwayf, Beni Suweif GovernorateAges 50 years+ - NCT07631221Recruiting
Protein Amount in Nutrition for Critically Ill Kidney Patients
This study tests whether different amounts of protein in tube feeding or IV nutrition affect kidney recovery in patients admitted to the intensive care unit (ICU) with kidney injury. The goal is to find the best protein level to help kidneys heal while patients are critically ill.
Buenos Aires, Buenos AiresAges 18 years+ - NCT07632196Recruiting
Nerve Stimulation to Improve Bowel Control After Rectal Cancer Surgery
This trial tests whether a small electrical device placed on the skin behind your ankle can help improve bowel control after surgery to remove rectal cancer. Many patients experience changes in bowel function after this surgery, and this treatment may help restore normal continence.
Manresa, BarcelonaAges 18 years+ - NCT07632742Recruiting
Two laser systems for prostate surgery: which works better?
This study compares two different laser technologies used during a minimally invasive prostate surgery called HoLEP. You'll be randomly assigned to one laser type and asked to complete brief surveys online after your procedure to help doctors understand which works best for reducing urinary symptoms.
Chicago, IllinoisAges 18–100 - NCT07635160Recruiting
Kidney Blood Flow Monitoring During Minimally Invasive Abdominal Surgery
This research study tests two imaging methods—ultrasound and a special light-based scanner—to monitor how well your kidneys receive blood during minimally invasive abdominal surgery. The goal is to understand kidney function better during this type of operation.
IstanbulAges 18–80 - NCT07635238RecruitingPhase 2
Lower Dose Radiation for Prostate Cancer
This trial tests whether a lower dose of radiation can effectively treat prostate cancer while reducing side effects. It is for men with certain types of prostate cancer that are visible on an MRI.
Basking Ridge, New JerseyAges 18 years+ - NCT07638865Recruiting
CoQ10 supplement for enlarged prostate symptoms
This trial tests whether a natural supplement called CoQ10 (Ralivia) can help reduce urinary symptoms caused by an enlarged prostate. You'll take the supplement and have your symptoms monitored over time.
ThessalonikiAges 50–80 - NCT07641049RecruitingPhase 1
CAR-NK Cell Therapy for Advanced Prostate Cancer
This trial tests a new type of immune cell therapy (CAR-NK cells) designed to target and fight advanced prostate cancer that has stopped responding to hormone treatments. The cells are engineered to recognize and attack cancer cells that have specific markers (PSMA and PSCA) on their surface.
Shenzhen, GuangdongAges 18 years+ - NCT07642440Recruiting
Suprapubic Drainage During Bladder Stone Removal Surgery
This trial tests whether a temporary drainage tube placed above the pubic bone during bladder stone removal surgery improves outcomes. You would be considered if you have a large bladder stone (over 2 cm) and are scheduled for minimally invasive surgery to break it up and remove it.
