Abstract
Midureteral obstruction is an extremely rare condition. This retrospective study assessed the outcomes of laparoscopic ureteroureterostomy (UU) in 13 children with midureteral obstructions. Records of patients with midureteral obstruction who underwent laparoscopic end-to-end UU between July 2011 and August 2015 were reviewed. The medical records comprised patient demographic data, intraoperative details, postoperative outcomes, and related complications. Renal ultrasound, magnetic resonance urography, and radioisotope renography were used for pre- and postoperative assessment. Success was defined as removal of symptomatic obstruction or improvement of hydronephrosis. Thirteen patients from 3.0 months to 12 years old were identified: 6 patients presented with asymptomatic hydronephrosis (according to the renal ultrasonography), 3 with intermittent abdominal pain, and 2 with gross hematuria. The remaining 2 patients presented with urinary extravasation after inguinal hernia repair and the Soave procedure, respectively. All patients underwent laparoscopic end-to-end UU. Procedures were performed using either the laparoscopic transperitoneal approach or laparoscopic retroperitoneal approach. All surgeries were performed successfully except for one case that required open surgery because of difficult anastomosis. There were no intraoperative or immediate postoperative complications. The etiology of the midureteral obstruction included congenital midureteral stricture, ureteral polyp, retrocaval ureter, and iatrogenic injury. The mean surgical time was 148.4 min, and postoperative hospital stay was 4.0-9.0 d. Postoperative outcomes were successful in all 13 patients (100%); median follow-up was 19.1 months. Laparoscopic UU was found to be feasible and safe for the management of midureteral obstruction in children.
