Urethral calculus with a recurrent acute urinary retention in a male child aged 11 years: A case report.

Urolithiasis is the presence of a stone anywhere in the urinary tract, it is commonly seen in adult patients and rare in children, especially when it is associated with acute urinary retention. In children, history is not suggestive and not specific; diagnosis is made by exclusion, and imaging studies often get the findings as incidental. In this case, the clinical presentation made early diagnosis quite difficult.
