Neurogenic Trauma During Delivery

Pelvic Floor Disorders

Abstract

One in four women will develop a pelvic floor disorder during their lifetime, and one in five will undergo surgery for prolapse or urinary incontinence. Pregnancy and childbirth are well-established risk factors for developing pelvic floor disorders. In fact, up to one third of women develop stress urinary incontinence after their first delivery, and 42% if those whose symptoms resolve in the first few months postpartum will have recurrent symptoms within 5 years.

Numerous translational studies going back as far as the 1980s support neurologic trauma to the pelvic floor muscles and striated urethral sphincter muscles as one mechanism by which pregnancy and delivery lead to pelvic floor disorders. There is also substantial evidence that anatomic injury to the pelvic musculature plays a significant role in postpartum pelvic floor disorders, including disruptions of the anal sphincter muscles and detachment of the levator ani from the pubic bones.

The pudendal nerve is susceptible to compression and stretch injury during childbirth as it travels through the fixed point of Alcock’s canal in the pelvis. Neurogenic trauma to the pudendal nerve primarily impacts three important pelvic floor structures: the striated urethral sphincter, external anal sphincter, and levator ani muscles.

The aim of this chapter is to explore the role of neurogenic trauma during delivery and its impact on pelvic floor function.
