Flexible tube versus shock wave for lower kidney stones
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study compares two common procedures to remove a kidney stone from the lower part of the kidney: flexible ureteroscopy (a tube with a camera to break up the stone) and shock wave lithotripsy (using sound waves from outside the body to break the stone). It helps determine which method works better for stones up to 15 millimeters.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years of age or older
- You have a kidney stone in the lower part of your kidney (lower calyx)
- The stone is 15 millimeters or smaller
- The stone is not too hard (measured by a CT scan, Hounsfield units less than 1000)
- You are not pregnant, do not have a bleeding disorder, and do not have an active urinary tract infection

Other trials that look related to this one.
This trial tests a new shock wave device to break apart a single kidney stone. It may be a good option if you have one stone between 6 and 15 mm that is not too hard or too far from the skin.
This study compares two ways of delivering sound wave therapy (ESWL) to break up kidney or ureter stones. One approach gradually increases the energy, while the other uses a fixed level, and the goal is to see which is more effective and comfortable for patients like you.
This trial compares two timing schedules for using shock waves to break up small kidney stones that remain after a surgical procedure. The goal is to find the best time to treat these leftover stones to help them pass naturally and prevent complications.
This trial compares two types of ureteroscopes (flexible and semi-rigid) to see which works better for removing stones in the upper part of the tube that carries urine from the kidney to the bladder. It may help you if you have a single stone there that's no bigger than 20 mm.
This trial compares two procedures to break up a single kidney stone. One uses sound waves from outside the body, the other uses a laser through a small scope. Both aim to help you pass the stone more easily.
This trial studies whether kidney-stone shockwave treatment works better when you lie on your back (supine) versus on your stomach (prone). It focuses on adults with a stone in the lower part of the urine tube (the distal ureter).
