Right Hydronephrosis Caused by Congenital Circumcaval Ureter in a Spinal Cord Injured Patient: A case report

ABSTRACT

Circumcaval ureter is one of the congenital anomaly in which aberrant development of the inferior vena cava (IVC) causes compression of the deviated ureter medially behind the IVC. The incidence is approximately one in 1500 cadavers and is three to four times more common in male. Although the lesion is congenital, symptoms attributable to this anomaly usually appear in young adulthood. This is a case of 17-year-old spinal cord injured man with a circumcaval ureter who was diagnosed as right hydronephrosis by routine evaluation for neurogenic bladder, incidentally. Suprapubic cystostomy was done for prevention of further urologic complication and the severity of hydronephrosis was not aggravated in follow up studies after 6 months. We suggest early routine evaluation for neurogenic bladder is very important for prevention of developing urologic complication caused by congenital urologic anomaly in the patients with spinal cord injury.
