[Leiomyoma of the bladder as a cause of unilateral ureteral obstruction associated with uterine leiomyoma and polycystic ovary].

A case of a female patient with bladder leiomyoma associated to uterus containing several leiomyomatous nodules and polycystic ovaries is presented. The diagnostic convenience that ecography can provide, showing neoformations and their definition with regard to neighbouring organic structures, is highlighted. The existing relationship between uterine leiomyomas and estrogens is outlined, as well as the action of GnRH agonists on such leiomyomas after long-term therapy.
