Antegrade retrieval of a distal ureteric stone during laparoscopic radical nephrectomy: a novel approach to a rare but important problem

Abstract

A concurrent diagnosis of renal cancer and ipsilateral obstructing ureteric calculi is rare. This scenario poses questions about order and approach of treating each condition. We present the case of a 51-year-old man who was thought to have passed a ureteric stone prior to undergoing left radical nephrectomy for cancer. Ongoing ureteric obstruction, however, became apparent intraoperatively. Rather than electing for retrograde treatment we were able to successfully remove the stone in an antegrade fashion, using a laparoscopic port to facilitate antegrade flexible ureteroscopy.
