[The diagnosis of nonorganic neoplasms of the lesser pelvis].

An analysis is presented of the data on 330 patients with extraorganic neoplasms of the small pelvis (ENSP), 110 of whom are children, 105 subjects had benign neoplasms, 225 presented with malignant neoplasia. ENSP are manifested primarily by pains in the pelvis and disturbances in physiological functions due to the adjacent organs and structures being squeezed. In applying for medical advice for the first time diagnostic procedures fail to show ENSP in each third (34.2%) patient. The diagnosis of ENSP is supposed to include several studies and it is multi-stage. The most valuable information concerning ENSP is provided by rectal and/or vaginal examination of pelvic cavity. A scheme was elaborated for establishing boundaries of the focus, determining the size of a neoplasm, as was the classification according to the stages and TNM system for the objective information to be obtained on localization, size and distribution of a neoplasm. Employed in the evaluation of patients were rectoscopy (in 158 patients), cystoscopy (123), roentgenography of bones and pelvic cavity (306), pelvic pneumography (79), excretory urography (175), rectosigmoidography (178), ultrasonography (102), computerized tomography (118), angiography (112) and other procedures, all these having been done in order to be able to make as accurate and precise a diagnosis as possible.
