A bifid ureter ~~(or~~, or ureter fissus), is an example of incomplete duplication of a duplex collecting system.

Epidemiology

Present in ~5% (range 1-10%) of the population ^1-2.

Gross anatomy

A bifid ureter is formed when there is a duplex kidney (separate pelvicalyceal collecting systems) drain into separate ureters, but the ureters unite before draining into the bladder at a single ureteric orifice ¹.

Rarely, one of the branches of a bifid ureter will be blind-ending and will not unite², as observed in the case 6².

Differential diagnosis

double ureter: persistent of ureters to drain at separate ureteric orifices in the bladder
