Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula
are
acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection(prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis),
obstruction(stricutre, impacted stone, Cunningham clamp or condom catheter) and trauma(instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and
infection.
These
calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors. 1)a ureteral or bladder calculus that is lodged in the urethra. 2) urethral trauma or stricture, 3) calcification and around a foreign
body
or
hair. The treatment of urethral diverticulum conbined with stone is excision of the diverticula with removal of stone.
