Mobile app vs. in-person pelvic floor exercises for leaky bladder
This trial compares two ways to treat stress urinary incontinence (leaking urine when you cough, sneeze, or exercise): doing pelvic floor exercises using a smartphone app at home versus attending supervised in-person sessions. The study tests which approach works better and is easier for women to stick with.

Accessory Artery Detection and Erectile Function After Prostate Surgery
This study examines whether finding a small extra blood vessel (accessory pudendal artery) on imaging before nerve-sparing prostate surgery helps predict how well men recover erectile function afterward. The goal is to improve sexual health outcomes for men treated for prostate cancer.
LondonAges 18–79 - NCT07600554RecruitingPhase 1
Imaging Study for Prostate Cancer Detection
This research study tests a new imaging scan (called 68Ga-OncoACP3-PET/CT) to help find prostate cancer and see where it may have spread. The scan uses a radioactive tracer to help doctors visualize cancer cells and decide on the best treatment options.
Bergamo, BergamoAges 18 years+ - NCT07601282Recruiting
Predicting Incontinence Risk After Pelvic Floor Surgery
This study helps doctors predict which patients may develop urinary incontinence (leakage) after surgery to repair pelvic organ prolapse (when pelvic organs drop into the vaginal canal). By identifying risk factors early, doctors may be able to better prepare patients and prevent this complication.
Shanghai, Shanghai MunicipalityAges 20–90 - NCT07601646RecruitingPhase 2
New Paste Treatment for Erectile Dysfunction
This trial tests a new alprostadil paste applied inside the urethra (the tube you urinate through) to help men with erectile dysfunction who haven't responded well to pills like Viagra. The goal is to find the right dose that safely improves erections.
Vancouver, British ColumbiaAges 21–75 - NCT07601932Recruiting
Patient Positioning During Kidney Stone Removal Surgery
This study compares different patient body positions during a minimally invasive procedure (flexible ureteroscopy) to remove kidney stones from the upper ureter. The goal is to find the best positioning to make stone removal easier and more successful.
New York, New YorkAges 18 years+ - NCT07602010Recruiting
Comparing CT and MRI scans for bladder cancer staging
This trial compares two imaging methods—CT and MRI scans—to see which one better shows how far bladder cancer has spread before surgery. If you have newly diagnosed bladder cancer and are planning surgery, this study may help doctors choose the best imaging for your care.
OsloAges 18 years+ - NCT07603011Recruiting
Catheter timing after prostate laser surgery for urinary problems
This study looks at how long patients should keep a urinary catheter (a tube that drains urine) after having laser surgery to remove prostate tissue. Researchers want to understand what timing works best for patients who couldn't urinate before surgery.
Eskişehir, EskişehirAges 18 years+ - NCT07605936Recruiting
Understanding Frailty in Older Men With Prostate Cancer
This study looks at how frailty (physical weakness and loss of strength) affects older men who have been diagnosed with prostate cancer. Researchers want to understand which men are at higher risk and how this might guide better treatment decisions.
Limerick, MunsterAges 65 years+ - NCT07607197RecruitingPhase 1/Phase 2
Immune Reset to Help Highly Sensitized Kidney Transplant Patients
This study tests whether a special immune-resetting treatment can help patients who have developed too many antibodies against donor kidneys get access to a compatible kidney transplant. The treatment uses chemotherapy and stem cell transplantation to 'reset' your immune system so it stops rejecting potential donor kidneys.
Barcelona, CataloniaAges 18–60 - NCT07607990Recruiting
Rectal Indomethacin to Prevent Catheter Discomfort After Prostate Surgery
This study tests whether a special suppository (indomethacin, a pain-relieving medication) placed in the rectum can reduce bladder catheter discomfort after laparoscopic prostate removal surgery. If it works, it could help patients recover more comfortably.
Hangzhou, ZhejiangAges 18–80 - NCT07608848RecruitingEarly Phase 1
Imaging study of new cancer-targeting radioactive drugs
This study tests two new radioactive drugs designed to find and image advanced breast or prostate cancer. The drugs use special imaging scans (PET and SPECT) to locate tumors and may help guide future treatment decisions.
Perth, Western AustraliaAges 18 years+ - NCT07611864Recruiting
Patient Experience with Oxygen Therapy for Radiation Injury
This study asks patients who have received hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) to help doctors understand how well it works for healing soft tissue damage caused by radiation therapy. Your feedback helps improve care for future patients.
StockholmAges 18 years+ - NCT07614256Recruiting
Imaging and pathology analysis to predict prostate cancer
This study uses advanced imaging scans (MRI and ultrasound) and lab analysis of tissue samples to better predict prostate cancer. If you've had or are planning a prostate biopsy or surgery, your imaging and tissue results could help doctors develop better tools to diagnose prostate cancer.
Liuzhou, GuangxiAges 40–90 - NCT07614880Recruiting
Two methods for removing bladder stones in children
This study compares two minimally invasive surgical techniques to remove bladder stones in children ages 2–14. Both approaches aim to break up and remove stones with less recovery time than traditional open surgery.
Banī Suwayf, Beni Suweif GovernorateAges 2–14 - NCT07616700RecruitingPhase 2
Long-term safety study of HSK39297 for IgA kidney disease
This study continues treatment with an experimental medicine called HSK39297 for people with IgA nephropathy, a condition where the immune system damages the kidneys. The trial will track how safe and effective the medicine is over time in people who already completed an earlier study.
BeijingAges Any age - NCT07617272RecruitingPhase 2
Testing a drug to shrink high-risk prostate cancer before surgery
This trial tests whether a hormone-blocking drug called darolutamide can shrink aggressive prostate cancer before surgery. Researchers will also use a special blood test to predict who benefits most from the treatment.
GothenburgAges 18 years+ - NCT07617896RecruitingPhase 2
Aminophylline to help remove kidney stones in children
This trial tests whether a medication called aminophylline, placed directly in the bladder during surgery, helps doctors access and remove small stones stuck in the lower ureter (the tube that carries urine from the kidney). It's designed for children whose ureter is difficult to reach during the initial procedure.
Banī Suwayf, Beni Suweif GovernorateAges 2–18 - NCT07617909RecruitingPhase 2
L-Citrulline vs. Tamsulosin for Kidney Stone Passage
This study tests whether L-citrulline (a natural amino acid) or tamsulosin (a common blood pressure medication) helps you pass a small kidney stone stuck in your ureter (the tube from kidney to bladder) without surgery. The goal is to compare which medicine works better and is safer.
Banī Suwayf, Beni Suweif GovernorateAges 18–60 - NCT07617922RecruitingPhase 2
Melatonin and solifenacin for ureteral stent discomfort
This study tests whether two medications—melatonin (a sleep aid) and solifenacin (a bladder-control medicine)—can reduce uncomfortable symptoms from a temporary plastic tube (ureteral stent) placed in your urinary system during kidney stone treatment. The goal is to find out if these drugs help you feel better while the stent is in place.
Banī Suwayf, BeniSuefAges 18–60 - NCT07617948RecruitingPhase 2
Aminophylline injection to help place ureteral stent for kidney stone blockage
This trial tests whether injecting aminophylline (a medication that relaxes muscles) into the bladder can help doctors place a stent (small tube) to relieve a blocked ureter caused by a kidney stone. The goal is to improve kidney function when one kidney is blocked and not working.
Banī Suwayf, Beni Suweif GovernorateAges 18 years+ - NCT07619157RecruitingPhase 1
ONO-3310 Study for Kidney Disease and Type 2 Diabetes
This early-stage trial tests a new drug called ONO-3310 in two groups: healthy adults and people with kidney disease caused by type 2 diabetes. The study aims to understand how the drug works and whether it might help protect kidney function in people with diabetes.
