ABSTRACT

Circumcaval or retrocaval ureter is a congenital malformation secondary to anomalous development of the inferior vena cava. It is relatively rare with an incidence of one in every thousand live births and is predominant on the right side. However, there are reports of cases on the left side that are usually associated with situs inversus and/or bilateral circumcaval ureter when there is vena cava duplication. Circumcaval ureter is more common in men than in women and the ratio is 3:1. The condition may be asymptomatic or it may be manifested through hematuria, urinary infections and pain in the back flank. The case of a 35-year-old man is presented who had a history of recurrent urinary infections and who presented with pain in the right back flank. Circumcaval ureter was diagnosed by helical tomography and resolved by thin ureteral segment resection, anastomosis and double-J catheter placement. Ureteroscopy was carried out after catheter removal and adequate caliber was visible in the anastomosed zone. The patient is asymptomatic at 10-month follow-up after surgery.
