The posterior pelvic compartment, defined as consisting primarily of the rectosigmoid colon and peritoneal-lined cul-de-sac, was evaluated in 104 patients. Tumors and pseudotumors (fluid- and feces-filled loops of bowel) were ultrasonographically analyzed according to: (a) morphology and echo characteristics, and (b) location within either the cul-de-sac or rectosigmoid colon. On routine examination, a striking similarity between pathological processes and pseudotumors was demonstrated; these were diagnosed correctly only by the use of a technique in which the rectosigmoid colon is filled with water. Combined distension of the urinary bladder and rectosigmoid colon also enabled localization and differentiation of abnormalities within the cul-de-sac.
对104例患者的盆腔后间隙进行了评估，该间隙主要由直肠乙状结肠和腹膜覆盖的直肠子宫陷凹组成。根据以下方面对肿瘤和假肿瘤（充满液体和粪便的肠袢）进行超声分析：(a)形态和回声特征，以及(b)在直肠子宫陷凹或直肠乙状结肠内的位置。在常规检查中，发现病理过程与假肿瘤之间存在显著相似性；只有通过一种将直肠乙状结肠充满水的技术才能正确诊断这些情况。膀胱和直肠乙状结肠的联合扩张也有助于直肠子宫陷凹内异常情况的定位和鉴别。
