Bifid ureter

Dr Matt A. Morgan and Dr Henry Knipe et al.

A bifid ureter, 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 unite 2, as observed in case 6. 

Differential diagnosis

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