Observations on vesical diverticulum in childhood

Area of Science:

• Pediatric Urology
• Surgical Innovation
• Renal Tract Pathology

Background:

• Vesical diverticula, outpouchings of the bladder, can occur in children.
• These diverticula are frequently associated with vesicoureteral reflux and potential upper tract damage.
• Bladder outlet obstruction is not always present in pediatric cases.

Purpose of the Study:

• To evaluate the surgical management of vesical diverticula in children without bladder outlet obstruction.
• To assess the association between diverticula, vesicoureteral reflux, and upper tract changes.
• To determine the most effective surgical intervention for these conditions.

Main Methods:

• Retrospective analysis of 78 children undergoing surgery for vesical diverticula.
• Correlation of diverticulum location with ureteral orifices and vesicoureteral reflux.
• Assessment of upper tract changes via excretory urography.
• Evaluation of surgical outcomes for different procedures.

Main Results:

• 89 diverticulum-ureteral units were analyzed; 83 were associated with vesicoureteral reflux.
• Upper tract changes were observed in 78% of refluxing units.
• Diverticulectomy combined with ureteroneocystostomy demonstrated a high success rate.

Conclusions:

• Vesical diverticula in children, even without obstruction, frequently lead to vesicoureteral reflux and renal damage.
• Diverticulectomy and ureteroneocystostomy is the preferred surgical approach.
• Isolated diverticulectomy or vesical neck revision has limited indications.
