A bladder stone within a congenital paraureteral diverticulum: a case report

Area of Science:

• Pediatric Urology
• Urologic Oncology
• Congenital Abnormalities

Background:

• Paraureteral diverticula are uncommon congenital anomalies in children.
• Bladder stone formation within these diverticula is exceptionally rare.
• Vesicoureteral reflux is a known complication of urinary tract abnormalities.

Observation:

• A 5-year-old boy presented with dysuria, indicative of a urinary tract issue.
• Imaging revealed a bladder stone within a right posterolateral paraureteral diverticulum.
• Voiding cystourethrogram confirmed the diverticulum and associated vesicoureteral reflux.

Findings:

• Cystoscopy identified a large stone within the paraureteral diverticulum.
• Surgical intervention included open diverticulectomy for stone removal.
• A right Cohen ureteroneocystostomy was performed to address vesicoureteral reflux.

Implications:

• This case represents the first reported instance of bladder stone formation in a congenital paraureteral diverticulum.
• The findings expand the understanding of potential complications associated with paraureteral diverticula in pediatric patients.
• Successful surgical management underscores the importance of prompt diagnosis and intervention for such rare urologic conditions.
