A case report of a bifid ureter and renal pelvis

Background: Double ureter is one of the anomaly of urethra that appears complete or incomplete. Incomplete duplication of ureter is known as bifid ureter, this kind of anomaly may be formed due to some error or disturbance in development of the ureteric bud which arises from the mesonephric duct around the 5th week. The ureteric bud grows and penetrates in to the metanephric tissue at about32cond day. However, sometimes the ureteric bud may divide before penetrating the metanephric tissue thus, giving rise to a bifid ureter having a single opening in to the bladder. According to recent studies (in the year 2000) on an average 3% excretory urograms show ureteral duplication, and the reference book of Grant`s range it around 0.5%. Case report: The present report is a rare case of a male cadaver aged about 65 years which has been dissected for medical students in department of anatomy. In dissection of abdominal cavity we have found that both kidneys including the liver, spleen, renal veins and inferior vena cava are unexpectedly has become enlarged, also we have recognized that the left ureter has been doubled and it ran to the rime of the true pelvis, then it joined together and connected to the bladder. The right ureter however, was completely normal, but the pelvis has been doubled instead. Conclusion: The majority of the investigations have reported this anomaly in association with other disease conditions but the present case is the unilateral incomplete bifid ureter & pelvis were associated with no other abnormality. The possible embryological reasons for the formation of bifid ureter are discussed.
