Bilateral Calculi in a Child With Bilateral Single System Ureteroceles.

Ureteroceles in children are detected with prenatal sonography and less commonly during the evaluation following a urinary tract infection. Rarely do ureteroceles in the pediatric population present with stones, particularly in a bilateral fashion. We present a case of a 5-year-old boy found to have bilateral intravesical single system ureteroceles harboring multiple large calculi treated successfully with a staged endoscopic approach.
