Male urethral calculi.

Male urethral stone is a rare clinical entity in western parts of the world, but continues to be common in developing countries. We report 26 cases of male urethral calculi, treated over a 6-year period. The age of the patients ranged from 12 to 67 years. The calculi were encountered all along the urethra, but predominantly in the posterior urethral region. We found multiple stones in 6 cases and large giant calculi in 5. Presentation, etiology, treatment, and prevention of these calculi are discussed.
