Abstract

[Accepted Research Article]

Background: Open ureteric reimplantation is considered to be the gold standard treatment for numerous anomalies involving vesico-ureteric junction. The study was conducted to determine the outcome of ureteric reimplantation surgeries in terms of clinical and radiologic improvement.

Methods: A retrospective cross-sectional study with a descriptive approach was implemented. All pediatric patients who underwent ureteric re-implantation surgery in Tikur Anbessa Hospital from September 1, 2015 to August 31, 2020 were included in the study. Data was collected using structured questionnaire from the patients' chart. Data was analysed using SPSS version 23. Patient characteristics, perioperative parameters, indications and outcomes of surgery studied.

Results: A total of 36 including 5 bilateral ureteric reimplantation were done for 31 patients during the study period. Among these 20(64.5%) were male while the rest were female; with male to female ratio of 1.8:1. Age ranged from 4 months to 12 years with the mean age of 41 months. Cohen trans-trigonal ureteric reimplantation techniques used in 22(61.1%), including all bilateral cases, while Politano-Leadbetter and Lich-Gregoire repair techniques used in 11(30.5%) and 3(8.3%) respectively. Complication occurred in 2(6.5%) patients. Around 94 % had their symptoms resolved and showed improvement on the degree of hydronephrosis as evidenced on ultrasound scan done within 6 months of surgical intervention which was confirmed with late ultrasound.

Conclusions: Pediatric open ureteric reimplantation is highly effective procedure in our setting. Ultrasound alone is found to be sufficient to follow the post-operative course of the disease in most patients without a need for other imaging studies.
