This trial tests a patient-centered approach to managing painful kidney/ureter stones that are blocking urine flow. It may help you choose the safest next step—such as treatment with a scope or careful observation—based on your symptoms and situation.
San Francisco, CaliforniaAges 18 years+ - NCT07297953Recruiting
Access sheaths and stents study for kidney stone treatment
This study looks at the use of a ureteral access sheath (a tube that helps the surgeon reach the kidney) in people who already have a ureteral stent (a small tube placed in the ureter) and are having a stone removal procedure called ureteroscopy. It aims to find out if using this sheath is helpful for treating stones in the kidney or ureter.
Ann Arbor, MichiganAges 18 years+ - NCT07559721Recruiting
Understanding Inflammatory Polyps in Kidney Stone Surgery
This study looks at what causes inflammatory polyps (growths) to form in the ureter when you have kidney stones. By understanding these risk factors, doctors hope to better predict and prevent complications during stone removal surgery.

Madison, WisconsinAges 18–89 - NCT07310797RecruitingPhase 4
Comparing two drugs to help pass a ureter stone
This trial tests two medications, mirabegron and tamsulosin, to see which works better for helping a single ureter stone pass without surgery. If you have a stone between 4 and 10 mm in size, are 18-75, and have good kidney function, this study may be for you.
New Taipei CityAges 18–75 - NCT07568990Recruiting
Ureteral Access Sheaths for Kidney Stone Removal Surgery
This trial tests different types of tubes (called ureteral access sheaths) used during a minimally invasive kidney stone removal procedure called RIRS. The goal is to see which type works best and causes the least damage to your ureter (the tube that carries urine from your kidney).
Çorum, ÇorumAges 18–75 - NCT05833386Recruiting
Silodosin before surgery to help pass an access sheath
This trial looks at whether taking silodosin before flexible ureteroscopy makes it easier to place a special tube (ureteral access sheath) used during kidney stone surgery. If it works, it may make the procedure more feasible and smoother for people having the planned surgery.
CairoAges 18 years+ - NCT06815120Recruiting
New stent study for kidney stone and cancer patients
This trial tests a new type of ureteric stent (a tube that helps drain urine from the kidney) against the standard stent. It is open to patients who have had a stent before and need a new one because of kidney stones or cancer pressing on the ureter.
Southampton, EnglandAges 18–99 - NCT07176026Enrolling by invitation
Follow-up for small kidney stones (≤4 mm)
This trial is for people who have a small kidney stone (less than 4 mm) in the ureter, seen on a CT scan, and don't need urgent treatment. It studies how best to follow up on these stones.
HelsingborgAges 18 years+ - NCT02298465Recruiting
Shockwave treatment for a kidney stone: lying down two ways
This trial studies whether kidney-stone shockwave treatment works better when you lie on your back (supine) versus on your stomach (prone). It focuses on adults with a stone in the lower part of the urine tube (the distal ureter).
Hong KongAges 18 years+ - NCT06830577Recruiting
Aminophylline for kidney stone removal surgery
This trial tests if placing aminophylline into the ureter during a stone removal procedure (flexible ureteroscopy) reduces complications. It may help people with kidney stones smaller than 2 cm who have not had a ureteral stent placed before.
Cairo, AbassiaAges 18 years+ - NCT07247617Recruiting
Flexible vs semi-rigid for upper ureter stones
This trial compares two types of ureteroscopes (flexible and semi-rigid) to see which works better for removing stones in the upper part of the tube that carries urine from the kidney to the bladder. It may help you if you have a single stone there that's no bigger than 20 mm.
