Two versus four weeks of stent before ureteroscopy
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares leaving a ureteral stent in place for two weeks versus four weeks before a second procedure to remove kidney stones. The goal is to see which waiting time makes the second procedure easier and safer.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You have a kidney stone in the kidney or upper ureter that is 20 mm or smaller.
- Your doctor could not place the scope during the first attempt, so a stent was placed.
- You are willing to have a second procedure after waiting two or four weeks.
- You do not have an active urinary tract infection, bleeding problems, significant kidney issues, or previous major ureter surgery.

This trial compares two types of temporary drainage tubes (stents) placed in the ureter—the tube that carries urine from kidney to bladder—after surgery to remove kidney or ureteral stones. The study measures which stent causes fewer uncomfortable symptoms during the 2-week recovery period.
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.
This study compares whether a special anti-reflux stent causes fewer symptoms than a standard DJ stent in children treated for kidney stones. The goal is to find which stent is more comfortable and has fewer side effects.
This trial is looking at whether placing a small tube (stent) in the ureter before a type of keyhole surgery for kidney stones helps with outcomes like pain and success of the procedure. It aims to see if this pre-treatment makes the surgery easier, potentially reducing complications and improving stone removal.
This trial studies whether some people can avoid getting a ureteral stent after ureteroscopy and lithotripsy for a kidney stone. It may help reduce stent-related discomfort while still keeping outcomes safe for the stone problem.
This study compares three different ways of placing a small tube called a stent in the ureter after stone-removal surgery. The goal is to find the best method to reduce discomfort and improve recovery.
