Objective: To investigate the clinical outcome of surgical treatment for long ureteral defect in children, we evaluated our experience of managing 6 children with the long defect utilizing laparoscopic ureteral reconstruction technique using Yang-Monti technique.
Materials and methods: Six children with long ureteral defect who underwent laparoscopic Yang-Monti ureteral reconstruction between January 2013 and March 2016 were reviewed. The diagnosis and outcomes of long ureteral defects were reviewed based on clinical and imaging data. We assessed preoperative clinical data and outcomes, and analyzed the experience of laparoscopic Yang-Monti ureteral reconstruction.
Results: The mean age of the patients was 8.5 years. The etiology of the ureteral defect was failed pyeloplasty in 4 patients, failed pyeloplasty and ureteral reimplantation in 1, and trauma in 1. The mean defect length was 5.83 cm. All operations were performed successfully with no serious intraoperative complications and no conversion. The average operative time was 314 minutes, the average intraoperative blood loss was 25 mL, the average drain removal was 3.83 days, the average start of oral feeding was 5.17 days, and the average postoperative hospital stay was 7.17 days. Six patients suffered Clavien I and II complications postoperatively and were managed conservatively. Two patients suffered Clavien III complications postoperatively and were managed by replacing stent. A diuretic T1/2 showed the improvement of differential renal function without urinary obstruction in all patients.
Conclusion: Laparoscopic Yang-Monti ureteral reconstruction is safe and feasible in children with an excellent outcome.
