Percutaneous endoscopic ureterolithotomy of two different stones in a single session.

The authors report a rare case of percutaneous endoscopic ureterolithotomy of 2 ureteral stones. Extracorporeal shock-wave lithotripsy (SWL) treatment of the renal stone was performed. The stone was crushed into 2 pieces, with 1 of them located in the upper part, and the other in the middle part of the ureter. Further SWL treatments and ureteroscopy were unsuccessful. The authors then decided to perform a percutaneous ureterolithotomy. In conclusion, percutaneous ureterolithotomy is a good choice of treatment, when ureteral stones cannot be removed by SWL or ureteroscopy.
