Multiple Stones in a Single-System Ureterocele in a Child

Area of Science:

• Pediatric Urology
• Nephrolithiasis
• Congenital Anomalies

Background:

• Ureteroceles are congenital cystic dilations of the distal ureter.
• Multiple calculi within a ureterocele are exceptionally rare, particularly in pediatric cases.
• Hematuria is a common presenting symptom of urinary tract calculi.

Observation:

• A 6-year-old boy presented with hematuria.
• Radiological imaging (X-ray and ultrasound) revealed multiple calculi in the urinary bladder.
• Surgical exploration identified a ureterocele containing these multiple calculi.

Findings:

• The primary finding was the presence of multiple calculi within a ureterocele, a rare pediatric urological condition.
• Postoperative (99m) Tc-Dimercaptosuccinic acid scan (DMSA) indicated normal renal function.
• The calculi were successfully removed during surgery.

Implications:

• This case underscores the importance of thorough investigation when multiple bladder calculi are found in children.
• It highlights ureteroceles as a potential, albeit rare, source of pediatric bladder calculi.
• Preservation of renal function is crucial and was achieved in this case.
