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. The right-sided diverticula was noted in eight (36,4%) children, the left-sided diverticula was in ten (45, 4%), and four (18,2 %) children had diverticula on both sides. The disease onset in twenty (90,1%) children was the acute urinary tract infection, and two (9,9 %) patients had manifestations of urinary dysfunction. The isolated bladder diverticulum was noted in seven patients, fifteen children had paraureteral diverticulum associated with vesicoureteral reflux, obstruction of ureterovesical junction was noted in six children. The isolated diverticulum was excised and the bladder wall was reconstructed. When the diverticulum was combined with the VUR or the UV obstruction, ureter neoimplantation was additionally performed.

Results. Conversion was noted in 3 (13,6%) cases, they were associated with gas leak into the retrovesical space. Acuter pyelonephritis developed after repair in one (4,5%) child. There were not any complications in patients during follow-up period from 6 months to 6 years. One boy 1 (4,5%) had recurrence of diverticula up to 1 cm in size without clinical manifestations.

Conclusion. The pneumovesicoscopic approach is an effective and safe approach for the treatment of bladder diverticulum in children.
