Monitoring blood pressure and heart rhythm during kidney support in sepsis
This study looks at how stable blood pressure and heart rhythm are in people with sepsis who need continuous kidney filtration. If you qualify, it may help researchers better improve care for critically ill patients receiving this treatment.
SeoulAges 18 years+ - NCT05438537Recruiting
Study of effects of surgery in upper urinary tract cancer
This study looks at what happens in and around the time of surgery for upper tract urothelial cancer. It may help doctors better understand how the disease and the body respond to treatment.
Hong KongAges 18 years+ - NCT05597540RecruitingPhase 3
Shorter antibiotics for kidney transplant kidney infections
This study compares giving antibiotics for 7 days versus 14 days to treat acute kidney infections (pyelonephritis) in people with kidney transplants. It aims to see if the shorter course works just as well and is safer or easier to complete.
BordeauxAges 18 years+ - NCT05401032RecruitingPhase 2
Tryptophan for urinary symptoms from prostate enlargement
This Phase 2 study tests whether tryptophan is safe and can improve urinary symptoms caused by an enlarged prostate (BPH). It focuses on men who have bothersome, stable symptoms and who would normally take tamsulosin.
BragaAges 50–74 - NCT05520346Recruiting
Tracking urine and stool in hospital after transplant
This study tests a new device that automatically tracks urine and stool output for patients in the hospital after a stem cell transplant or for heart failure. The device could replace manual tracking and make it easier for your care team to monitor your fluid balance.
Durham, North CarolinaAges 18–80 - NCT07202819Recruiting
Chemotherapy and MRI before bladder surgery
This study looks at how well MRI scans can detect bladder cancer after chemotherapy, before surgery to remove the bladder. It may help doctors know if the chemo is working.
Asyut, Asyut GovernorateAges 18 years+ - NCT05495633Recruiting
Tracking outcomes after Rezum treatment for prostate blockage
This trial is collecting information about how well Rezum water-vapor treatment works for men with prostate blockage and urinary symptoms. It’s mainly focused on whether different kinds of patients do well, using surveys and clinic follow-up, not on changing your treatment plan.
GrazAges 18 years+ - NCT05175885Recruiting
Kidney transplant test using machine perfusion outside the body
This study tests a special way to keep and treat a donated kidney using a machine before it’s transplanted. The goal is to improve transplant outcomes for certain people on the kidney transplant waiting list.
ZaragozaAges 18 years+ - NCT05570994Enrolling by invitationPhase 1/Phase 2
PSMA-targeted radioactive drug for advanced prostate cancer
This Phase 1/2 study tests a radioactive treatment that targets PSMA, a protein often found on prostate cancer cells. It’s for men whose prostate cancer has worsened despite hormone-blocking pills like abiraterone or enzalutamide, aiming to help shrink or control the disease.
Vancouver, British ColumbiaAges 18 years+ - NCT05010343RecruitingPhase 2
Carbon ion radiation guided by scans for prostate cancer
This Phase 2 trial tests whether using detailed scans (PSMA PET/CT and MRI) to guide carbon ion radiation—delivered in a focused way—can treat localized prostate cancer. It may help target the treatment more precisely while avoiding areas that are not involved.
ShanghaiAges 45–85 - NCT04987073Recruiting
Vitamin D type added for CYP24A1 vitamin D deficiency
This study tests a vitamin D-like medicine for people with a specific genetic cause of low active vitamin D (CYP24A1 deficiency). If you have the right gene change, it may help your body use vitamin D more normally.
Caen, NormandyAges 18 years+ - NCT05080998Recruiting
Tracking bladder cancer recurrence with repeated urine tests
This study follows people with past bladder cancer to see how bladder cancer comes back over time. You would provide urine samples at several visits, which helps researchers evaluate urine tests that may spot recurrence earlier.
Miami, FloridaAges 18 years+ - NCT04794582Recruiting
Preventing a belly hernia after first kidney transplant
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+ - NCT05084768Recruiting
Test blood markers to predict kidney transplant rejection
This study looks at special blood tests to help predict when kidney transplant rejection might happen. If the markers work, they could help doctors catch rejection earlier and adjust treatment sooner.
Loma Linda, CaliforniaAges 18 years+ - NCT04797039Recruiting
MRI-guided freezing treatment for localized prostate cancer
This trial studies a treatment where doctors use MRI pictures to guide freezing of a prostate tumor. It may help men with smaller, well-placed prostate cancers who cannot or do not want surgery or radiation right now.
Rochester, MinnesotaAges 30–100 - NCT05071131Recruiting
Inulin supplement to improve gut health in kidney disease
This trial studies whether taking inulin—a dietary fiber—can improve gut bacteria and the gut barrier in people with end-stage kidney disease on hemodialysis. It may help reduce gut-related problems that can affect overall health in kidney disease.
BerlinAges 18–75 - NCT05245591RecruitingPhase 2/Phase 3
Pentosan for bladder irritation after pelvic radiation
This trial studies whether pentosan polysulfate sodium can reduce bladder bleeding (hematuria) and urinary symptoms caused by radiation cystitis after pelvic cancer radiation. It may help people who are still having these bladder problems more than 6 months after radiation.
TaipeiAges 20 years+ - NCT04931537Recruiting
Testing early kidney marker tests for people with diabetes
This study looks for early warning signs in blood or other samples (using a special lab approach) to detect kidney problems sooner in people with diabetes. It may help patients and clinicians identify kidney risk earlier and follow changes over many years.
HangzhouAges 18–80 - NCT05124886Recruiting
Study gut–kidney link in people with bowel or stone problems
This study looks at how problems in the gut can lead to kidney stone risk, especially in people with inflammatory bowel disease or after certain weight-loss surgery. Your participation may help researchers understand the gut–kidney connection and identify why stones happen.
New York, New YorkAges 18–80 - NCT04865939RecruitingPhase 3
Gemcitabine treatment compared with bladder wash in UTUC surgery
This Phase 3 trial studies whether using gemcitabine (a chemotherapy medicine) in the urinary tract better prevents cancer from coming back than using a simple water wash. It involves people with upper tract urothelial carcinoma who are having curative surgery to remove the affected ureter or kidney tube.
Dallas, TexasAges 18–90 - NCT05248620Recruiting
Antibiotics to prevent infections in hemodialysis catheters
This trial tests whether taking preventive antibiotics (or a placebo sugar pill) can lower the risk of infections in people who receive hemodialysis through a catheter. It may help protect you from serious catheter-related infections, but you must be able to follow the study’s medicine and consent rules.
Copenhagen, Capital RegionAges 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+ - NCT05089994Recruiting
Pain-control injections after bladder surgery
This trial compares two different injection techniques to reduce pain after radical cystectomy (bladder removal surgery). It may help find which approach gives better pain relief with fewer side effects.
AsyutAges 40–70 - NCT05234463Recruiting
Study links complement activity to IgA kidney disease severity
This study looks at how parts of the immune system (called complement) may relate to how severe IgA kidney disease is. It may help doctors understand disease activity better, even if the study is mainly observational.
