Stenting before mini-keyhole kidney stone surgery
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 70 years old.
- You have a kidney stone in one kidney that is between 10 and 20 mm in size.
- You are scheduled to have a specific type of keyhole surgery to remove the stone (RIRS).
- You do not have an active urine infection.
- You can attend follow-up appointments, including a CT scan 4 weeks after the 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 study looks at whether placing a temporary tube (called a stent) in the ureter after kidney stone surgery is always necessary. Some patients get a stent to help urine flow, but it can cause discomfort. The trial aims to see if skipping the stent is safe and leads to fewer symptoms. If you are having kidney stone surgery, participating might help determine the best approach for recovery.
This study looks at patients who have kidney stones and a urinary tract infection that spreads to the blood. It compares two ways to drain urine urgently before the main stone removal surgery, to see which leads to better outcomes.
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.
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 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.
