Port Site Recurrence Following a Robotic Laparoscopic Radical Nephroureterectomy for Sarcomatoid Variant of Urothelial Carcinoma.

Port Site Recurrence (PSR) following laparoscopic tumor resections has been reported for a variety of tumors. Though PSR is a rare phenomenon, they most commonly occur following nephroureterectomies for upper tract urothelial carcinoma. Herein we report a novel case of a PSR following a robotic assisted nephroureterectomy for the sarcomatoid variant of urothelial carcinoma of the upper urinary tract.
