Our knowledge of the immediate effects of parturition on pelvic floor anatomy and physiology has been sparse. However, with the introduction of computed tomography, ultrasonography, and magnetic resonance imaging, new tools have become available for visualizing dynamic antenatal and postpartum changes in the pelvic musculature. Although few studies have been performed, there is evidence of a pregnancy-related increase in the frequency of urinary stress incontinence, and of an increased frequency of persistent anal incontinence in cases of sphincter tears.
我们对分娩对盆底解剖结构和生理功能的即时影响了解甚少。然而，随着计算机断层扫描、超声检查和磁共振成像技术的引入，已出现新的工具来观察盆腔肌肉组织在产前和产后的动态变化。尽管相关研究较少，但有证据表明，妊娠相关的压力性尿失禁发生率增加，以及括约肌撕裂导致的持续性肛门失禁发生率上升。
