Proximal ureterouretheroanastomosis in the treatment of kidney double in children

Objective. The aim of this study was to present the laparoscopic end-to-side ureteroureteroanastomosis technique in a young child a treatment option of duplex kidney. Material and methods. In the present study, a retrospective study of the medical history of a patient who underwent laparoscopic ureteroureteroanastomosis for duplication of the left kidney was performed. The indication for surgery was obstruction of a well-functioning upper segment. Results. The duration of the operation was 80 minutes. The drainage tube was removed after the control ultrasound on the 2nd day. The patient was then discharged for outpatient follow-up. The follow-up period was 12 months. The patient was asymptomatic throughout the control period. A repeat ultrasound examination performed 3, 6, and 12 months after surgery demonstrated a decrease in the anteroposterior diameter of the pelvis to 5 mm. There was no dilatation of the ureters. Conclusion. Laparoscopic ureteroureteroanastomosis is a safe and reproducible treatment for children with kidney duplication and can be used as an alternative to other methods. The case report demonstrated the possibility of laparoscopic end-to-side ureteroureteranastomosis in young children without signs of stenotic disorder of the recipient ureter.
