    Abstract:
    INTRODUCTION: To overcome the tension of anastomosis between ureter and bladder for complex ureteroneocystostomy in children, we describe a novel technique utilizing an ipsilateral umbilical ligament (occluded umbilical artery) to fix the bladder. TECHNICAL CONSIDERATIONS: From July 1991 to December 2013, 18 patients (13 girls, 5 boys) underwent our technique for complex ureteroneocystostomy. Median age at surgery was 61 months. The main indications for surgery were ectopic ureter in 9 patients, primary obstructive megaureter in 3, and persistent vesicoureteral reflux after surgery in 2. The ipsilateral umbilical ligament was ligated. A new hiatus was created craniolateral to the original hiatus. The submucosal tunnel was created trans-trigonally. The umbilical ligament was sutured to the whole bladder muscle at the hiatus. Ureteroneocystostomy was then performed. Mean duration of postoperative follow-up was 62.6 months. Seventeen patients underwent unilateral ureteroneocystostomy with our technique. One patient underwent bilateral ureteroneocystostomy with our technique on one side. Vesicoureteral reflux was not shown in 92.3% of patients and no signs of obstruction developed in any patients. No complications were encountered with our procedure. CONCLUSIONS: Utilizing an umbilical ligament for ureteroneocystostomy to fix the bladder is an excellent option when the distal ureter creates tension in uretero-bladder anastomosis. This method seems to be applicable in many cases of complex ureteroneocystostomy in children.
