At times, kidney stones attempt to pass without success and may get lodged in the ureter (the tube that empties urine from the kidney to the bladder). When this happens your physician can perform a procedure to remove the kidney stone from your ureter. Under anesthesia, your physician will place a tube in through your bladder by the way of your urethra to your ureter to directly view and remove or break up the stone and remove it from the ureter. A Ureteroscope may stretch out the ureter and a soft rubber tube may be left in your ureter for some time to promote healing and allow for your kidney to drain.
