Most of the ureteric abnormality cases are asymptomatic but they may be of undue importance to surgeons and urologists because such rare cases may pose problems for diagnosing & treating. Even though ureteric anomalies are very frequent this was a very interesting case of multiple ureteric abnormalities including bladder abnormality. In routine dissection of 20 cadavers during the academic year 2009-10 in the Department of Anatomy, Osmania medical college a rare case of unilateral left bifid ureter was detected in a female cadaver aged about 50 years. This is a case left bifid ureter with 2 major pelvises united with the right ureter just before opening into the bladder and they opened into the bladder with single orifice. Bladder abnormality was also found to be present without any trigone formation as the right and left ureters are united before opening into the interior of the bladder therefore, not having postero-lateral angle of the internal trigone, usually formed by right and left ureteric orifices. The base which is normally formed by the inter-ureteric ridge is also absent. This has occurred due to the development of ureters from a single ureteric bud which again divided to form a left bifid collecting system. Probably the single ureteric bud is the cause for absence of trigone formation.
