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

摘要

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. On-going 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.
