Đánh giá kết quả phẫu thuật bảo tồn đơn vị thận trên ở bệnh nhân thận niệu quản đôi hoàn toàn tại Bệnh viện Nhi Trung ương

Complete ureteral duplication is a common congenital anomaly of the urinary system. Prenatal diagnosis increases the chances of preserving the upper renal unit in patients with surgically treated ureteral duplication. Surgical treatment includes various methods such as ureteroureterostomy, ureteral reimplantation into the bladder, and ureterocele incision. The choice of technique depends on the morphological characteristics of the lesion. Objective: To evaluate the outcomes of preservation surgery for the upper renal unit in patients with complete ureteral duplication at National Children Hospital. Subjects and Methods: A retrospective descriptive study involving 61 patients who underwent preservation surgery for complete double ureters at National Children Hospital from January 2018 to June 2022. Results: Ureter-to-ureter anastomosis was performed in 37 out of 61 patients (60.6%), with good outcomes in 97.3% of cases. Ureteral implantation into the bladder was done in 12 out of 61 patients (19.7%), with good outcomes in 91.7%. Ureteral diverticulum creation was performed in 12 out of 61 patients (19.7%), with good outcomes in 66.7% of cases. Conclusion: The surgical procedure in this study were effective and safe when appropriately indicated based on the morphological characteristics of the lesions.
