[The complex diagnosis of nonorganic neoplasms of the small pelvis]

The paper discusses the results of examination of 205 cases of extra-organ tumors of the small pelvis carried out in 1967-1986. The study group included 65 pediatric and 140 adult patients, 57 (28%) males and 148 (72%) females, 194 primary and 11 relapsing cases. Patients aged under 4 years (47, i. e. 23%) prevailed. Benign tumors were detected in 83 (40.5%) and malignant ones--in 122 (59.5%) cases. Disease was asymptomatic in 39 (19.0%) patients and presented with multiple symptoms in 166 (81.0%). Rectally, the upper pole of lesion was palpable in 47 (22.9%) while the lower one--in all cases. Tumors which took up as much as two-thirds of the small pelvis cavity were found in 37 (56.9%) pediatric and 31 (22.1%) adult patients. Tumorous or secondary lesions of adjacent organs were detected rectoscopically in 47 of 74 (63.5%) cases: sensitivity (s)-88.6%, specificity (sp)-57.1%; using chromocystoscopy--in 43 of 64 (67.2%): s-89.5%, sp-75.0%; pelvic pneumography-31 of 56 (55.3%): s-68.8%, sp-54.5%; excretory urography-53 of 79 (67.0%): s-88.3%, sp-68.4%; irrigoscopy-55 of 79 (69.6%): s-82.4%, sp-75.0%; angiography-30 of 70 (42.8%): s-90.9%, sp-78.4% and computer tomography--in 42 of 45 (93.3%) patients: s-96.4%, sp-88.2%. Four stages of diagnosis were suggested.
