Your doctor will place a tiny flexible probe through your urethra and up the ureter toward the stone. The probe has two electrodes at the end. Images will help locate the stone. After the stone is located, the device will be used. An electrical spark will break the stone. A special basket or forceps may be used to grab the stone fragments and remove them. The stone fragments may be allowed to pass in the urine.
Depending on the size of the stone, more than one probe may be used. A stent may be placed in the ureter. It will help protect the lining while the stone fragments pass or damage is being repaired.
There may be fragments that are too large to pass after the procedure. These can be treated again with lithotripsy.
How Long Will It Take?
30-60 minutes depending on the size and location of the stone
How Much Will It Hurt?
