Pneumovesicoscopic Transvesical Ureteric Reimplantation for the Correction of Congenital Lower Ureteric Anomalies in Children: A Regional Arabian Gulf Multicenter Retrospective Experience.

Objective: To report and compare the outcomes of 3 different techniques of pneumovesicoscopic ureteric reimplantation applied in children.

Methods: The study included 178 renal units in 105 patients who underwent pneumovesicoscopic reimplantation between January 2016 and October 2021. Presentation, indication for surgery, surgical technique, operative time, operative details, days of hospitalization and catheterization, and outcome were retrieved from patients' electronic records.

Results: The collected data was revised, coded, tabulated, and fed into the computer using the Statistical Package for Social Science (SPSS 25). Data were presented, and the appropriate statistical analysis was performed according to the type of data obtained for each parameter.

Conclusion: The pneumovesicoscopic approach to ureteric reimplantation is not inferior to the data reported in the literature for open approach in terms of success rate (94%). In addition, pneumovesicoscopy permits the evaluation of the trigonal anatomy in situ, which can have a significant impact on the selection of the most appropriate surgical technique.
