A rare cause of urinary retention in A child: A case report.

A Ten-year-old child presented to our emergency department with acute urinary retention. Three months ago, he was diagnosed with right renal hydronephrosis with renal calculus. Firstly, right nephrostomy was inserted. Next, he had been treated with ESWL for right renal stone in another center. After unsuccessful attempts for urethral catheterization, he was brought to the operating room for meatotomy and calculus extraction. An impacted urethral stone was detected at this point. He had a successful extraction of the stone. A six-month follow-up period has passed with no recurrence. This shows that although they are uncommon, urethral stones do happen.
