Bifid ureter
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
