Long-term safety of two kidney stone scope methods
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You were 18 or older when you had the procedure.
- You had a kidney stone up to 20 mm (about the size of a grape) that was treated with a scope through your urinary opening at Al-Azhar University Hospitals between 2020 and 2025.
- You did not have a stent or a nephrostomy tube in that kidney before the procedure.
- At least 12 months have passed since your procedure.
- You have not had any other surgery or condition that could narrow the ureter (the tube from kidney to bladder) on the same side.

Other trials that look related to this one.
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 study tests a new device that removes kidney stones using suction and a camera together. It aims to make the procedure more efficient and possibly reduce the need for multiple surgeries.
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 ways of removing kidney stones during a procedure called flexible ureteroscopy. One method uses a special sheath that helps suction out stone fragments, which may improve stone removal and recovery.
This study looks at how safe and effective a minimally invasive procedure called RIRS (using a flexible scope to break up and remove stones) is when done under local anesthesia instead of general anesthesia. If you have a kidney or upper ureteral stone, this may help you avoid general anesthesia and recover faster.
This trial compares a robotic system to a manual tool for removing kidney stones. It aims to see which method works better for people with normal kidney anatomy.
