Detrusor overactivity in Becker muscular dystrophy.

A 20-year-old man with normal motor milestones as an infant but subsequent progressive difficulty in walking in childhood, was genetically confirmed to have Becker muscular dystrophy (BMD) at age 13. He was independent in ambulation and activities of daily living. He was referred to the Department of Uro-neurology for a 5-year history of urinary urgency and incontinence. He would visit the toilet 10 times in the daytime and experience urinary urgency daily, often associated with incontinence. He did not report difficulties initiating voiding, stress incontinence, pain, or hematuria. There was no history of urinary tract infections.
