With the development of extracorporeal shock wave lithotripsy (ESWL), improved endourologic instrumentation, and medical dissolution therapy, the need for open ureterolithotomy has become less common. Open operation is occasionally necessary when less invasive techniques fail. As in many of the surgical specialties, laparoscopy has become more common in urologic surgery. We recently experienced three cases of ureteral stones, which were treated by laparoscopic ureterolithotomy. The stones were all large and impacted stones. The patients were a 73-year-old man and two 34-year-old men. All procedures were performed by a retroperitoneal approach. We used Roticulator endo mini-shears resourcefully, when we incised the ureteral wall. After surgery, all three patients were stone-free, and hydronephrosis was improved.
