Perineal nerve injury due to stretching is caused by excessive traction on the distal motor branches of the pudendal nerve that innervate the perineum and anus. These injuries can occur in a number of morbid conditions (prolapsus, anorectal dyschezia, pelvic surgery) and induce denervation of the pelvic floor that very probably modifies the resistance of the sphincters. Stretch injuries should be considered when discussing physiotherapy or surgery for urinary incontinence. Diagnosis can be established by electrophysiologic studies of the perineum, particularly by measurements of distal pudendal nerve motor latencies. The authors report a series of sixty patients with stretch-induced neuropathy.
拉伸导致的会阴神经损伤是由支配会阴和肛门的阴部神经远端运动分支受到过度牵拉引起的。这些损伤可发生在多种病态情况下（脱垂、肛门直肠排便困难、盆腔手术），并导致盆底失神经支配，这很可能改变括约肌的阻力。在讨论尿失禁的物理治疗或手术时应考虑拉伸损伤。诊断可通过会阴部的电生理研究来确立，特别是通过测量阴部神经远端运动潜伏期。作者报告了一系列60例拉伸诱发神经病变的患者。
