Retrocaval ureter with hydronephrosis

ABSTRACT

Retrocaval ureter is one of the rare congenital anomalies. We report a case of retrocaval ureter who presented with right lumbar pain, renal stone and hydronephrosis. The diagnosis was made on intravenous urography which showed typical "J" shape deformity in the proximal dilated ureter with moderate hydronephrosis. CT scan mapped out the course of ureter. The patient was operated and findings were confirmed. The ureter was transected near the pelvis, renal stone removed and a uretero-uretral anastomosis with anteriorisation of the ureter performed
