Abstract

Complete duplication of the renal collecting system is a common congenital anomaly in the pediatric urological system. The surgical intervention is determined based on the morphological characteristics of each patient's pathology. Various surgical methods have been employed with the aim of preserving renal function and minimizing kidney resection. Ureteral-ureteral anastomosis surgery is one commonly applied method. Objective: Evaluate the surgical outcomes of ureteral-ureteral anastomosis in the treatment of complete duplication of the renal collecting system in children. Subjects and Methods: A retrospective analysis of 37 patients who underwent ureteral-ureteral anastomosis surgery for complete duplication of the renal collecting system at the National Children's Hospital from January 2018 to June 2022. Results: The male-to-female ratio was 1:3.6. The average age was 20 ± 19 months (2 – 72 months). The most common clinical presentation was urinary tract infection, accounting for 54%. Surgical outcomes included an average operating time of 82.8 minutes, with the main injury being dilation of the upper renal unit (94.6%). No cases of bleeding or injury to the lower renal unit were reported, with one case of residual obstruction postoperatively. The average postoperative hospital stay was 3.3±1.3 days. Postoperative follow-up showed favorable outcomes in 34 out of 71 patients (91.9%): no clinical symptoms, non-dilated or reduced size of the renal collecting system compared to preoperative conditions. Conclusion: Ureteral-ureteral anastomosis surgery is a safe and effective procedure with low complication rates, feasibility, and positive outcomes.
