We present a unique case of a large urinary bladder stone protruding through the external urethral meatus in a 77-year-old woman, which was causing acute urinary retention, complicated by bilateral hydronephrosis, and was removed under topical anesthesia in the emergency department. Epidemiology, etiology, clinical presentation and management of urinary bladder stones are briefly discussed.
