A novel case of laparoscopic ureterolithotomy in a partial duplex ureteric collecting system: can open procedures still be justified in the minimally invasive era? Context: Impacted ureteric stones can pose a treatment challenge due to the high level of failure of ESWL and endourological approaches. Laparoscopic ureterolithotomy can provide a safe and successful alternative to these and open, invasive procedures. Interval laparoscopic ureterolithtomy was carried out following placement of a percutaneous nephrostomy. This was performed through an trans-peritoneal approach with the ureterotomy closed by intracorporeal suturing and placement of a JJ stent without the need for an abdominal wound drain.

Laparoscopic ureterolithotomy is a safe, minimally invasive method of managing large, impacted ureteric stones with minimal associated patient morbidity.
