Multiple calculi in a single-system orthotopic ureterocele in a two-year-old boy presenting with hematuria: A case report

Ureterocele is the dilatation of the submucosal ureter as a result of a defect in the Chwalla membrane absorption. The many types and clinical presentations of ureters present a significant challenge to clinicians. Although stone formation in the ureterocele is common in adults, it is much less common in pediatric patients. Here, we present a case report of a two-year-old boy with single-system ureteroceles containing multiple small stones.
