Norepinephrine irrigation fluid for kidney stone surgery
This study tests whether adding norepinephrine (a medicine that helps narrow blood vessels) to the fluid used during kidney stone surgery can reduce bleeding. It is for people with stones in the kidney or upper ureter who are having a specific minimally invasive surgery.
Nanjing, JiangsuAges 18–75 - NCT07767773Recruiting
Long-term safety of two kidney stone scope methods
This study is checking the long-term safety of two different ways of doing a kidney stone scope procedure (one uses a small tube to guide the scope, the other does not). If you had this procedure for a kidney stone (up to 20 mm) and it's been at least a year, they want to follow up with you to see how you're doing.
CairoAges 18 years+ - NCT07763613Recruiting
Study of pelvic floor strength after kidney stone surgery
This study measures a new score called the pelvic floor fatigue index, which looks at how tired the pelvic floor muscles get, in people who have a ureteral stent placed after kidney stone surgery. The goal is to see if this score can help predict or prevent bladder problems that stents can cause.
Trabzon, TrabzonAges 18–65 - NCT06651294Recruiting
Study of kidney stone supplement after laser treatment
This trial tests a supplement called Neorenal Forte to help clear tiny leftover kidney stone pieces after laser surgery. If you have small fragments left after your procedure, this study may help you get rid of them.
BurgasAges 18–65 - NCT07506031Recruiting
Predicting ESWL Success for Children's Kidney Stones
This study uses a special ultrasound technique (called shear wave elastography) to predict how well shock wave therapy (ESWL) will break up kidney stones in children. It may help doctors decide the best treatment for your child's stone.
Banī SuwayfAges 1–18 - NCT07742358Recruiting
Comparing ureteral stent designs in children with kidney stones
This trial compares two types of ureteral stents (small tubes that help urine drain from the kidney to the bladder) in children having surgery for kidney stones. The goal is to see which type causes fewer symptoms like pain or discomfort.
Toronto, OntarioAges 8–18 - NCT07101809Recruiting
Comparing two ways to remove kidney stones
This study compares a standard kidney stone removal procedure (ureteroscopy with laser) to a newer suction-based technology. If you have a kidney stone that needs surgery, this trial may help your doctor find the best way to remove it.
Birmingham, AlabamaAges 18 years+ - NCT04430426Enrolling by invitation
Study for kidney stone patients with an AGXT gene change
This study looks at people age 18+ who have a history of calcium oxalate kidney stones and who have a specific AGXT gene change found on genetic testing. It involves following a controlled diet for five days, which may help researchers understand how diet affects kidney stones in this group.
Birmingham, AlabamaAges 18 years+ - NCT05297331Recruiting
Kidney stone registry for adults who can consent
This trial is a global registry that collects information about people treated for kidney stones. It helps researchers learn about patterns of care and outcomes so treatments can improve over time.
Hong KongAges 18 years+ - NCT06158620RecruitingPhase 1/Phase 2
Nasal spray for pain after ureter stent placement
This trial tests whether a nasal spray form of the painkiller ketorolac can safely reduce pain from a ureteral stent after stone surgery. If you are having a ureteroscopy with stent placement, this might help you manage discomfort without stronger medications.
