The anomaly of duplication of the ureter and pelvis has been recognized for many years. At first it was an anatomic curiosity, found at autopsy or at operation; later it was diagnosed clinically on rare occasions, until now this anomaly is realized to be one of the most common of all urinary malformations and the etiologic factor in many renal lesions. Double ureters have been classified as: 1. Complete, wherein two pelves on the same side, one superior to the other, drain by separate ureters and open by separate orifices on to the floor of the bladder. The openings may lie side by side or one may be superior to the other. They may also be closely situated or set at some distance apart. 2. Incomplete duplication, the branched or cleft ureter, wherein two pelves and two upper ureters join to enter the bladder by one common ureter and orifice.
