The urogenital system is more likely to have birth defects than any other system. Of all the urinary tract anomalies, Double ureter is the most common one. It may be incomplete (bind ureter) or complete duplication. In order to collect data for this various medical colleges were approached & 120 cadaveric kidney pairs were examined for the presence or absence of double ureters. It was found that 02 out of all examined kidney pairs were showing this anomaly. One pair was having bilateral double ureters while other was showing right sided ureteric duplication.
