Study of bladder and sphincter symptoms in functional neurological disorders
This study looks at bladder and sphincter (urine control) symptoms in people with functional neurological disorders. It may help doctors understand what causes these symptoms and how to better treat them.
BobignyAges 18 years+ - NCT02900040Recruiting

This trial is about setting up and using a kidney-transplant database linked to stored blood/tissue samples. It may help researchers better understand kidney transplant outcomes and improve future care.
LyonAges 18 years+ - NCT04969354RecruitingPhase 1
CAIX-targeted CAR-T therapy for advanced kidney cancer
This early-phase study tests a lab-made immune treatment (CAIX-targeted CAR-T cells) for advanced kidney cancer that has not gone away with standard targeted therapy or immunotherapy. If eligible, the goal is to see if the treatment can safely shrink the cancer and improve outcomes.
Xuzhou, JiangsuAges 18–70 - NCT04871568Recruiting
Compare two sites for dialysis catheter placement
This trial tests whether placing a dialysis catheter in one location (subclavian/near the collarbone) is as good as placing it in another (jugular/neck) for patients who need a temporary dialysis catheter. It aims to reduce problems like vein narrowing caused by catheter placement.
LundAges 18 years+ - NCT05521698RecruitingPhase 1
Bicalutamide study for early bladder cancer in men
This trial tests whether bicalutamide can help men with non-muscle invasive bladder cancer (an early form that hasn’t spread into muscle). It is a Phase 1 study, meaning the main goal is to see how safe it is and learn how it behaves in the body for this cancer type.
Tucson, ArizonaAges 18 years+ - NCT04397159Recruiting
Exercise program to reduce tiredness in some kidney patients
This trial studies whether doing a combination exercise program can reduce “fatigability,” meaning feeling unusually tired or weak during activity, in Veterans with moderate-to-advanced chronic kidney disease. It also compares results with people without kidney disease and checks for safety, especially for heart and joint health.
Washington D.C., District of ColumbiaAges 50–85 - NCT04314323Recruiting
Registry for idiopathic retroperitoneal fibrosis in China
This study is a registry that collects medical information (and sometimes tissue results) from people with retroperitoneal fibrosis that is not caused by another known condition. It may help doctors better understand the disease and improve future care.
Beijing, Beijing MunicipalityAges 18–75 - NCT05090722Recruiting
PureWick Device for Nighttime Urination in Women
This study tests a device called PureWick that helps manage frequent nighttime urination in women. If you wake up 2+ times per night to urinate, this trial explores whether the device can improve your sleep and quality of life.
New York, New YorkAges 50 years+ - NCT04026776RecruitingEarly Phase 1
Study hormones and salt sensitivity in adults born preterm
This early-phase study looks at natural body chemicals (uric acid and klotho) and how sensitive your blood pressure may be to salt. It may help researchers understand long-term health risks in people born very early.
Winston-Salem, North CarolinaAges 22–33 - NCT03959904Recruiting
Compare belly-skin closure methods after kidney transplant surgery
This study looks at which abdominal wall (belly) closure technique helps reduce the chance of an incisional hernia after a kidney transplant. If you’re having a kidney transplant, it may help surgeons choose a method that lowers this complication for future patients.
ManchesterAges 18–70 - NCT04376216RecruitingPhase 4
Prednisolone for biopsy-proven acute interstitial kidney inflammation
This trial tests whether prednisolone (a steroid medicine) helps people with acute interstitial nephritis, a sudden inflammation of the kidney tissue. You may qualify if your diagnosis was confirmed by kidney biopsy and your kidney function has worsened recently.
HerningAges 18 years+ - NCT04444440RecruitingPhase 4
Antibiotic prevention after bladder Botox for overactive bladder
This trial studies whether taking an antibiotic around the time of bladder Botox can lower the risk of urinary infections. It’s for women with overactive bladder who tried standard medicines but didn’t get enough relief.
Edmonton, AlbertaAges 18 years+ - NCT04558593Recruiting
Watching complex kidney cysts with regular scans
This study monitors people who have complex kidney cysts to see how they should be followed over time and whether it helps guide treatment. You may get regular imaging (scans), and you’ll be asked to complete questionnaires in English or French.
Calgary, AlbertaAges 18 years+ - NCT04312854Recruiting
Study of IRPF in adults in China
This study follows adults in China who have IRPF (idiopathic retroperitoneal fibrosis). It aims to better understand the condition and may help improve how it’s diagnosed and managed over time.
Beijing, Beijing MunicipalityAges 18–75 - NCT04597372RecruitingPhase 2
Tamsulosin for bladder urine retention after pelvic surgery
This trial studies whether tamsulosin can help drain the bladder when urine builds up after pelvic reconstructive surgery. It may help reduce the time and problems caused by “post-operative urinary retention.”
Pittsburgh, PennsylvaniaAges 18 years+ - NCT04110821Recruiting
Quality of life after prolapse treatment, surgery or non-surgery
This study looks at how people’s quality of life changes after treatment for pelvic organ prolapse, comparing conservative (non-surgical) and surgical options. It may help doctors understand which approach leads to better day-to-day well-being for similar patients.
BaselAges 18 years+ - NCT04526431Recruiting
Tacrolimus dose study in early kidney transplant patients
This study looks at how tacrolimus (a rejection-preventing medicine) should be dosed in the first days to years after a kidney transplant. It may help personalize dosing by comparing different patient groups, including using genetic testing.
Grenoble, Auvergne-Rhône-AlpesAges 18 years+ - NCT04378400Enrolling by invitation
Check outcomes after laparoscopic sacrocolpopexy surgery
This study looks at short-term complications and longer-term results after laparoscopic sacrocolpopexy done at the study unit. It may help the clinic understand how well the surgery is working and how to improve care, based on follow-up questionnaires and check-ins.
LeuvenAges Any age - NCT04239703Recruiting
Kidney transplant biopsy study using blood test clues
This study looks at kidney transplant patients who are getting a kidney biopsy for usual clinical reasons. It tests whether special blood test results (from a sample taken as part of the study) can help spot transplant kidney problems earlier or more accurately.
Tampa, FloridaAges Any age - NCT04610372Recruiting
Targeted radiation plus hormone therapy for prostate cancer spread
This study compares different ways of giving radiation (SABR or brachytherapy) along with long-term hormone therapy for men whose prostate cancer has spread to a limited number of spots in the body. It aims to see which radiation approach controls the cancer as well as possible while keeping quality of life in mind.
Kelowna, British ColumbiaAges 18 years+ - NCT03955172Recruiting
Test of everolimus to reduce transplant rejection
This trial studies whether everolimus can improve outcomes for people whose kidney transplant biopsy shows signs of a specific type of immune attack. It focuses on patients without certain antibodies and with particular biopsy findings, aiming to prevent rejection-related injury while balancing medication side effects.
LyonAges 18 years+ - NCT04546230Recruiting
Epidural anesthesia for keyhole kidney removal surgery
This trial studies using a small-needle spinal/epidural type pain medicine delivered to your back during a keyhole kidney removal. It may help control pain and reduce the need for stronger pain medicines during and after surgery.
CairoAges 18–70 - NCT02812212Recruiting
Test a kidney scan to spot early blockage in newborns
This study checks whether a specific kidney test (a renogram scan) can detect a significant urine blockage early in babies born with ureter-pelvic junction obstruction (a narrow connection between the kidney and ureter). It may help clinicians decide sooner which babies need closer follow-up or treatment.
BordeauxAges 4 weeks–2 months - NCT03636464Recruiting
Antibiotic testing in people on kidney dialysis
