Circumcaval Ureter - Congenital Vascular Cause Of Obstructive Hydronephrosis.
Circumcaval ureter is a relatively uncommon congenital cause of obstructive hydronephrosis resulting from anomalous formation of the infra renal inferior vena cava (IVC). It usually presents in 3rd – 4th decade and affects males more than females. Treatment involves surgical correction in symptomatic patients whereas conservative management and follow up is suggested in asymptomatic patients. We report a case of 25 year old male presenting with right flank pain and symptoms of recurrent urinary tract infection. CT (Computerized tomography) urography demonstrated the ureter encircling the IVC with a normal distal course lateral to the IVC. Laparoscopic transposition with end-to-end anastomosis of the right ureter was performed.
