The retrograde flexible ureteroscopic renal stone removal through a laparoscopic port and a ureterotomy site is feasible compared with the RIRS and it is more effective than the postoperative SWL.
We report our experience of laparoscopic retroperitoneal ureterolithotomy with renal stone extraction using a stone basket under flexible ureteroscopy through a laparoscopic port and a ureterotomy site in patients with both large upper ureteral stone and small renal stones.
Of these patients, 11 with large upper ureteral stone and renal stones underwent laparoscopic retroperitoneal ureterolithotomy with renal stone extraction using stone basket under flexible ureteroscopy through a laparoscopic port and a ureterotomy site.
The ureterotomy was performed with a laparoscopic knife.
After the ureteral stone removal, the flexible ureteroscopy was inserted into the ureter, renal pelvis and calyces through a laparoscopic port and a ureterotomy site.
The Double J-stent was used formerly in 6 patients; it was indwelled by antegrade introduction of a 6Fr 26-cm Double J-stent through the 2- or 5-mm trocar and the ureterotomy. The Double J-stent was passed down the ureter into the bladder first, then up the ureter to the renal pelvis.
