Obstructive leiomyoma of the female urethra: report of a case.

We report a case of leiomyoma of the female urethra and review the literature. A mass protruding from the urethral meatus during voiding caused dysuria. Urodynamic study showed an obstructive pattern with low maximum urine flow and high detrusor pressure in initiating voiding. Cystourethroscopy revealed a mass extending from the proximal segment of the left lateral urethral wall into the bladder. At transurethral resection of the tumor 12.2 gm. of tissue were excised. Histopathological studies confirmed urethral leiomyoma. Surgery completely resolved the original symptoms of dysuria.
