Functional ectopic ureter in case of ureteric duplication in children: initial experience with laparoscopic low transperitoneal ureteroureterostomy.

ABSTRACT

PURPOSE: In this paper, we discuss the value of the laparoscopic ipsilateral ureteroureterostomy for duplication anomalies of the urinary tract in children. MATERIALS AND METHODS: A laparoscopic retroperitoneal ureteroureterostomy was undertaken in 2 children with 3-mm instruments and a 30-degree 5-mm optical trocar. Cystoscopy and stent placement in the recipient ureter was performed at the beginning of each procedure. The end-to-side anastomosis was performed with running 60 sutures. The type of procedure, position of operating devices, postoperative stenting, hospital stay, and outcome were recorded; each child had a control ultrasound at 6 months of follow-up. RESULTS: The two operations were performed on girls. Patients were 8 and 18 months of age, respectively. Diagnosis was, in each case, obstructed upper pole ureter, without reflux and with a functioning upper pole. Operative time was 120 minutes. There were no intra- and no postoperative complications. Patients were discharged home after 4 and 7 days. Ultrasound at 6 months after the operations showed an important decrease of the ureterohydronephrosis in one case and a complete disappearance of any dilatation in the second case. Parenchyma of the upper poles were considered as normal. CONCLUSION: Initial results of the minimally invasive ipsilateral ureteroureterostomy were excellent, with a minimal requirement of analgesia and perfect cosmetic results. Long-term follow-up, concentrating on the absence of urinary infection and of destruction of the upper poles, is mandatory.
