Although prostatic calculi are common, complications are fortunately rare. Here, we report a case of prostatic calculi causing urethral obstruction. A 66-year-old man presented with severe voiding difficulty and urge incontinence. He was found to have multiple large prostatic calculi obstructing the prostatic urethra as well as several bladder calculi. Attempts at endoscopic removal were unsuccessful, which resulted in an iatrogenic urethral diverticulum due to fragmented calculi. The residual calculi and diverticulum were removed successfully by open surgery.
