   Abstract 

Retrocaval ureter (RCU) is a rare congenital anomaly with the ureter looping around inferior vena cava (IVC). We present the case of 10-year-old boy. Diagnosis was confirmed with ultrasound and CT. He underwent retroperitoneoscopic uretero-ureterostomy.

   Introduction Top


Retrocaval ureter (RCU) is a rare congenital anomaly with the ureter looping around inferior vena cava (IVC).[1] Although it is a congenital anomaly, the patient presents later in life, from a resulting hydronephrosis. The hydronephrosis is due to kinking of the ureter. We present a 10-year-old boy with right flank pain and associated right hydronephrosis. The diagnosis was confirmed with ultrasound and computed tomography (CT). He underwent retroperitoneoscopic ureteroureterostomy.


   Case Report Top


A 10-year-old child presented with a 2 years history of right flank pain, intermittent colicky, or dull aching in nature. The child was not hypertensive. Physical examination was unremarkable. Abdominal ultrasonography revealed a right hydronephrosis with prominent right upper ureter. CT urography was done as a part of academic interest showed right hydronephrosis and moderate dilatation of right upper ureter up to 4.5 cm. The ureter seen looping behind IVC with a normal course in distal part [Figure 1]. The images showed classical fish hook appearance for RCU.

The patient underwent retroperitoneoscopic surgery. The intraoperative findings confirmed the diagnosis of right RCU it was seen looping around the IVC [Figure 2]. The procedure carried out involved mobilization and dividing the ureter at the medial borders of the IVC. An uretero-ureteric anastomosis using vicryl 5-0 suture was carried out after untangling it with IVC without tension with the placement of a double-J ureteric stent.

RCU is a rare anomaly. Diagnosis can be made with the help of ultrasound and urography (intravenous, CT or by magnetic resonance imaging).[2] The treatment is as it was done in this case. The images provided give a clear understanding of the anomaly for a surgeon to understand and identify. The prognosis is excellent if treated adequately.
