[Uterine perforation and localization of an IUD in the bladder associated with bladder calculosis. Report of a case and review of the literature].

A case is reported of the presence of an intrauterine device into the bladder due to uterine perforation with calculus formation in a 39 year old woman, with two pregnancies after its installation. The patient was seen for complaints of pelvic pain, pollakiuria, dysuria and tenesmus, without uterine sintomatology. The case was studied in July of 1993 in the General Hospital "Vicente Guerrero" of Acapulco. To our knowledge only 19 previous cases have been reported in the literature of migration of an intrauterine device into the bladder with calculus formation. The literature is reviewed and we discuss the clinico-radiological findings.
