Diverticula of the male urethra.

Recently, we have seen 8 patients, ranging in age from 4 to 72 years, who each had a diverticulum of the anterior urethra. Our experience with these patients, combined with a thorough review of the literature, has demonstrated that while the cause and classification of these lesions often are controversial, multifaceted and confusing, the best treatment may be determined simply through accurate description of the size, thickness and anatomic location. Many diverticula, regardless of their cause, are contained within an intact corpus spongiosum and can be treated successfully transurethrally. Those diverticula that may leave a cavity too large to drain well, are too thick to cut transurethrally or lack adequate surrounding supportive tissue are treated bet by open surgical excision and urethral closure.
