Ureteral Access Sheaths for Kidney Stone Removal Surgery
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
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).
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 75 years old
- You have kidney stones smaller than 2 centimeters (about the size of a small bean)
- You are scheduled to have retrograde intrarenal surgery (RIRS)—a minimally invasive procedure to remove kidney stones
- You do not have an active urinary tract infection
- You do not have a bleeding disorder or take blood-thinning medications that cannot be stopped
- You are able to lie on your back with your legs up (the lithotomy position) during surgery

This trial compares a vacuum-assisted ureteral access sheath to a standard one during kidney stone surgery (retrograde intrarenal surgery). The goal is to see which might work better and be safer for patients.
This trial tests if using negative pressure suction during ureteroscopy can reduce fluid absorption and infections. It may help people undergoing kidney stone surgery.
This study tests a technique during kidney stone removal surgery (RIRS) where the surgeon fully drains the kidney system at the end of the procedure. Researchers want to see if this approach improves how quickly patients recover and reduces complications.
This trial compares two ways of removing kidney stones during a procedure called ureterorenoscopy (a tube with a camera is used to reach and remove the stone). The aim is to see if using suction during the procedure helps remove stones more effectively than the standard method.
This trial compares two methods used during surgery to treat kidney stones. It looks at whether one type of tube (a fan-shaped access sheath) causes less kidney injury after surgery than the standard tube. This could help patients have a safer recovery.
This trial compares two different tubes used during surgery to remove kidney stones. The goal is to see if one type works better than the other for clearing stones safely.
