Pneumovesicoscopic diverticulectomy in children. International multicenter study

Introduction. Over the last few years, some publications have appeared documenting removal of bladder diverticulum using a pneumovesicoscopic approach. The objective of this study is to present multi-center experience of pneumovesicoscopic diverticulectomy. Material and methods. We studied retrospectively 22 medical records of children who underwent surgery from 2012 to 2019 in seven hospitals. There were sixteen (72,7%) boys, six (27,3 %) girls. The medium age was 76 months.
