In our case, the lower blind ending bifid ureter was clearly demonstrated in the 45 minute film and it appears dilated and tortuous likely secondary to uretero-ureteral reflux.
Refers to a duplex kidney with the two separate pelvicalyceal collecting systems uniting at the PUJ or as bifid ureters.
Duplex system is explained as the kidney with two pyelocaliceal systems, which may have either single or bifid ureter
(partial duplication) or double ureterdraining separately into the urinary bladder (complete duplication), with a single renal parenchyma that is drained by two pyelocaliceal systems4.

Trifid pelvis and controlateral bifid ureter
with bilateral ureteropelvic junction obstruction.

Supernumerary kidneys on the left showed a bifid ureter.
