“…Although it is clear that vaginal delivery contributes to the development of postpartum SUI, the exact mechanism is not well-defined and likely involves neurologic, muscular, and supportive tissue damage. Clinical evidence suggests that vaginal childbirth injury results in neuromuscular and ischemic damage in the bladder outlet and urethra, which contributes to the subsequent risk of developing SUI [41]. Damage to the ligaments, fascial support, and pelvic floor musculature also occur with vaginal childbirth and are associated with SUI.…”

Large-scale population-based surveys published in the past decade give new insights regarding risk factors for stress urinary incontinence (SUI) in women. Age plays a significant role in the development of all forms of urinary incontinence, but findings regarding the role of hormonal changes are inconsistent. Obesity is an increasingly prevalent health condition that was shown to have detrimental impact on SUI development, while weight reduction was proven to reduce SUI. Other modifiable risk factors, such as diabetes, also are related to SUI. Pregnancy, delivery, and pelvic floor surgery are risk factors discussed in the review. Recent genetic studies identified several genes encoding components of the extracellular matrix, which could be related to a predisposition to SUI. Identifying risk factors for SUI can facilitate prevention strategies in an aim to reduce SUI prevalence among women.

“…Damage to the ligaments, fascial support, and pelvic floor musculature also occur with vaginal childbirth and are associated with SUI. In addition, the pudendal nerves are susceptible to injury during vaginal childbirth, particularly as they pass between the sacrospinous and sacrotuberous ligaments [41].…”

“…44,45 Although there is variability in the appearance of the pelvic support structures even in asymptomatic nulliparous women, 46 significant differences in levator muscle volume, shape, and integrity have been shown between asymptomatic individuals and those with incontinence and pelvic prolapse. 47 The levator muscles should be assessed for areas of asymmetric thickening or atrophy (Fig.…”

Physical examination alone is often inadequate for evaluation of pelvic floor dysfunction. Magnetic resonance imaging (MRI) is a robust modality that can provide high-quality anatomic and functional evaluation of the pelvic floor. Although lack of standardized technique and radiologist inexperience may be relative deterrents in universal acceptance of pelvic floor MRI, the role of MRI is increasing as it is technically feasible on most magnets and offers some advantages over the traditional fluoroscopic defecography. This review focuses on the technical and interpretational aspects of anatomic and functional pelvic floor MRI.

“…The use of 3-dimensional ultrasound to assess the configuration of the genital hiatus and continuity of the levator muscle has been described [22,24,84]. In addition to the pelvic floor muscle, detailed images of the urethra and vagina are technically feasible with MRI, to assess for morphologic alterations in their associated support structures [85][86][87][88][89][90][91].…”
