Urethral calculi are uncommon problem in urological practice. The incidence of these stones is reported to be lower than 0.3% in the literature. The majority of urethral calculi originates from upper urinary tract or bladder and migrates into the urethra. Native forms are generally associated with postsurgical changes or anatomic abnormalities such as strictures and urethral diverticula. In this paper, we discussed posterior urethral stones in three patients without any urethral anatomic abnormality who were admitted to our clinic over a period of 5 years.
