Urethral calculi occur when renal or bladder stones migrate into the urethra. These migrants stones are 10 times more common than stones that form de novo in the urethra. Symptoms include dysuria, poor urinary stream and recurrent urethritis. Diverticula or pseudodiverticula and urethral stricture are predisposing factors. The majority of urethral stones are radiopaque. The calculus most often is found in a midurethral diverticulum in the female patient, and in the male patient it is discovered frequently in the bulbar or prostatomembranous urethra.
