Background: To analyze the clinical efficacy and experience with laparoscopic ureteral end-to-side anastomosis at the pelvic level for a duplex kidney (DK) in children.
Methods: This was a retrospective analysis of 20 children diagnosed with a complete DK in the pediatric surgery department of the Affiliated Hospital of Southwest Medical University between January 2018 and July 2024. The cohort comprised 15 girls and five boys aged 5-100 months (mean ± SD, 38.5 ± 29.9). There were 16 cases on the left side and four cases on the right side. There were five cases of simple upper ureterovesical junction stenosis, seven cases of upper ureteroceles, seven cases of upper ureteral ectopic opening, and one case of postoperative vesicoureteral reflux with fenestration for upper ureteroceles. The major clinical symptoms were intermittent perineal urinary leakage and repeated infection of the urinary tract. Laparoscopic duplex ureteral end-to-side anastomosis (between the end section of the upper ureter and the lateral section of the lower ureter) at the pelvic level was performed in all patients with an intraoperative indwelling ureteral stent.
Results: Laparoscopy with no conversion to open was undertaken in the 20 cases. The duration of the procedure was 85-140 (112.9 ± 14.3) min. Intraoperative blood loss was 5-15 (8.2 ± 4.4) ml. Postoperative duration of hospital stay was 5-9 (6.5 ± 0.9) days. No anastomosis fistula, anastomotic stenosis, ureteral stump infection or other complications occurred. The ureteral stent was removed 8 weeks after surgery. All children were followed up for 4-68 (median, 32) months. Clinical symptoms disappeared, and the degree of upper renal hydronephrosis decreased.
Conclusions: Laparoscopic ureteral end-to-side anastomosis at the pelvic level for a DK in children is safe and efficacious. It is a minimally invasive procedure that is simple with few complications, and merits wider popularization.

Introduction: Robotic uretero-ureterostomy (RUU) is a minimally invasive surgical technique that has gained popularity in recent years, especially for the treatment of duplex systems, as an alternative to ureteral reimplantation.
Aims Of The Study: Focusing on technical considerations and supporting its use, we aim to describe our procedure and results in children.
Materials And Methods: From November 2018 to December 2023, we collected data on RUU performed by Da Vinci Surgical Robot Xi® in pediatric patients at our center.

To describe the operative technique and outcome of one trocar-assisted retroperitoneoscopic ureteroureterostomy (OTAU) in 40 cases of complete ureteral duplication in children. From September 2016 to December 2020, 40 patients (12 male and 28 female) less than 10 years of age underwent OTAU. A transverse skin incision of 12 mm in length was created approximately 1 cm above the iliac crest.

Background: Approximately 15% of patients undergoing radical cystectomy (RC) develop benign ureteroenteric strictures. Of these strictures, the majority are located in the left ureter. To lower the rate of strictures, a retrosigmoid ileal conduit has been suggested.

Background: Right versus left kidney donor nephrectomy remains a controversial topic in renal transplantation given the increased incidence of right kidney vascular anomalies and associated venous thrombosis. We present the case of a 3-year-old pediatric recipient with urethral atresia and end-stage kidney disease who received a robotically procured living donor right pelvic kidney with two short same-size renal veins and a short ureter.
Methods: We utilized a completely deceased iliac vein system (common iliac vein with both external and internal veins) to extend the two renal veins.
