To demonstrate the pelvic peritoneal recesses during voiding, evacuation proctography was combined with positive contrast peritoneography.
In 30 constipated patients, peritoneography was performed, followed by proctography.
During evacuation rectogenital herniation developed in 20 patients (66%), without visceral filling in 12 (40%).
Posterior pelvic floor hernia is common during defecation. Less than half fill with bowel and many may not be apparent on standard proctography.
为了在排尿时显示盆腔腹膜隐窝，将排粪造影与阳性对比剂腹膜造影相结合。
对30例便秘患者进行腹膜造影，随后进行直肠造影。
在排便过程中，20例患者（66%）出现直肠生殖疝，12例（40%）无内脏充盈。
排便时盆底后部疝很常见。不到一半的疝内有肠管充盈，许多在标准直肠造影中可能不明显。
