ABSTRACT

Female pelvic anatomy is a complex combination of muscles, ligaments, nerves, and blood

vessels that act dynamically to provide support for the urethra, bladder, uterus, and rectum. An

understanding of normal mechanisms of pelvic support are essential in the evaluation of women

with voiding complaints, urinary incontinence, and bowel dysfunction related to pelvic floor

relaxation. Thus, the treatment of female urinary incontinence often involves recognition and

treatment of concurrent pelvic pathophysiology such as cystocele, uterine prolapse, enterocele,

rectocele, and perineal laxity. Identification of the various components of pelvic floor

dysfunction is aided by diagnostic tools such as video urodynamics and magnetic resonance

imaging of the pelvis. This chapter will focus on normal female pelvic anatomy, including

the supporting structures relevant to voiding dysfunction and incontinence, as well as the

pathophysiology of pelvic floor relaxation, with a description of the various components of

pelvic organ prolapse.
