Kidney stone removal under local anesthesia
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a kidney stone or a stone in the upper part of the ureter (the tube that carries urine from the kidney to the bladder) that is between 1 and 4 centimeters (about the size of a small grape to a large cherry).
- You are between 18 and 70 years old.
- You are generally healthy or have only mild to moderate overall health issues (classified as ASA I, II, or III).
- You do not need surgery for stones in the middle or lower part of the ureter.
- You do not have any anatomical problems in your urinary tract, such as a narrowed ureter, an abnormally shaped kidney, or a duplicated kidney.
- You do not have severe heart, brain, or lung disease, and you are not pregnant.

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 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.
This trial tests a robot-assisted telescope-guided procedure to break up kidney stones. It may be an option if you have a kidney stone smaller than about 1.6 cm and are already scheduled for a ureteroscopy (RIRS).
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 different surgeries for removing a single kidney stone that is 2 to 3 centimeters in size. One method uses a flexible scope with a suction tube, and the other uses a small incision in the back. The goal is to see which works better and has fewer side effects.
This study compares two types of anesthesia during endoscopic kidney stone surgery to see which one helps the surgeon work more comfortably. It might help improve the procedure for patients like you.
