Unilateral Duplicated Collecting System Identified During Pelvic Lymphadenectomy: A Case Report and Literature Review.

Anatomic variations can be an additional challenge for any surgeon, especially in complicated surgical procedures, and they could lead to complications if not identified timely. We present a case report of an incidental intraoperative finding of unilateral duplicated ureter, identified during pelvic lymphadenectomy for a patient who underwent surgical treatment for ovarian cancer. Also, we include an update on this anatomic variation following the literature review. The importance of a systematic approach in the identification of the relevant anatomy and landmarks, taking into consideration the variation of the duplicated ureter, is emphasized in this paper and may contribute beneficially to the experience of surgeons operating in this field.
