Leiomyomas of the urinary tract are benign and uncommon forms of tumor. In
the present study, two cases have been described of leiomyomas situated in
the bladder. Following this description, the pathological characteristics a
nd the diagnostic and therapeutic aspects of these lesions have been examin
ed. The clinical symptomatology depends on the tumor site, and this type of
lesion is more frequently found in women. Treatment mainly consists of end
oscopic resection, but may involve cystectomy. The prognosis for patients w
ith this type of tumor is invariably favorable. (C) 2001 Editions scientifi
