Duplication of Ureter in the Cadaveric Dissection: A Systematic Review

Abstract

Ureteric duplication is the most common anomaly of urinary system. It may be complete, incomplete, unilateral or bilateral. In the present systematic review, we searched online databases according to PRISMA method for the availability of literature in the form of original research articles as well as case reports describing the duplication of ureter in the human cadaveric dissection for the duration from January 2011 to May 2020. We include 8 original research articles and 14 case reports in the present study. We thoroughly discuss all these articles on the basis of unilateral or bilateral; complete or incomplete duplication of ureter as well as other associated abnormalities of urogenital system. Data compilation of all these studies show higher incidence of left incomplete ureteric duplication as compared to right incomplete ureteric duplication. No such difference was found for the incidence of left and right complete ureteric duplication.
