Retrocaval ureter (RCU) is a rare congenital anomaly and published data on pediatric laparoscopic management are poor. The aim of this study was to report our experience of retroperitoneal laparoscopic approach for management of RCU in children.
A retrospective review of data from patients treated for RCU between 2002 and 2018 in our institution was performed. All patients were positioned in a flank position and underwent a three-port (5-mm optical trocar and two 3-mm trocars) laparoscopic retroperitoneal ureteroureterostomy. Anastomosis was made by 6/0 absorbable sutures. A JJ stent was always inserted.
Five patients with a median age of 94 months (5–152) were operated on and followed up for a median time of 103 months (46–201). Median operating time was 200 min (160–270). No conversion and no transfusion occurred. Median hospital stay was 2 days (1–4). Ureteral stent was removed after 52 days (47–82). Complications included pyelonephretis (N = 1). In all cases, hydronephrosis decreased postoperatively.
Retroperitoneal laparoscopic approach for RCU is safe and effective in children. Our video demonstrates different patients with specific surgical details to show how to manage these children. The global vision of the upper tract by laparoscopy leads to optimal management of these children even if the anomaly was not detected preoperatively.
