Cystosonography in the staging of gynecological malignancy.

Five patients with carcinoma of the cervix and one with carcinoma of the vagina were examined by both cystoscopy and endosonography. Both techniques revealed malignant infiltration of the bladder in 4 patients. In the other 2 cystoscopy showed an intact bladder mucosa despite cystosonographic evidence of invasion of the bladder wall by tumor.
