Presentation of an ingested foreign body as a vesical calculus: a common condition, but uncommon presentation

Abstract

Vesical calculus is a common entity in children of developing countries. Foreign body ingestion is a common occurrence in the pediatric population. An ingested foreign body eroding into the urinary bladder and leading to the formation of a vesical calculus is an extremely rare condition. We encountered a 14-year-old girl who presented with a vesical calculus and a history of ingestion of a nut bolt 7 years earlier. After cystolithotomy and retrieval of the calculus, we noticed that the nut bolt formed its core. As it is an extremely uncommon presentation, it is being reported here, with a brief review of the literature.
