The aims of this study were to evaluate pelvic floor dysfunction symptoms one year after delivery and investigate whether adverse functional outcomes after childbirth were related to the degree of perineal injury. A prospective cohort of 776 primiparas were included. Self-reported pelvic floor function data were obtained using a web-based questionnaire. Women with no/first-degree injuries, second-degree injuries, third-/fourth-degree injuries (obstetric anal sphincter injury, OASI) and cesarean section were compared. A total of 511 women (66%) responded. Second-degree tears were a risk factor for stress incontinence (aOR 2.6 (95% CI 1.3–5.1)). Cesarean section was protective against stress incontinence (aOR 0.2 (95% CI 0.1–0.9)). OASI was a risk factor for urge incontinence (aOR 4.8 (95% CI 1.6–15)), prolapse (aOR 7.7 (95% CI 2.1–29)) and pelvic pain (OR 3.3 (95% CI 1.1–10)). Dyspareunia was reported by 38% of women, 63% of women in the OASI group (aOR 3.1 (95% CI 1.1–9.0)). Women with OASI reported that the injury affected daily life (OR 18 (95% CI 5.1–59)). Pelvic floor dysfunction is common after childbirth, even in women with moderate injury. Women with OASI had significantly higher risks of symptoms of prolapse, urge urinary incontinence, pain, dyspareunia and impacts on daily life.

Introduction Obstetric anal sphincter injury (OASI) complicates around 5% of deliveries in primiparas. The study objective was to assess the utility of three‐dimensional endoanal ultrasonography (3D‐EAUS) in the diagnosis of OASI. Material and methods The present study was designed to mirror screening settings with an unselected cohort of nulliparous women. All enrolled patients underwent clinical examination of the perineum by the caregiver, and 3D‐EAUS was conducted. Post‐processing of ultrasonography volume data was performed by an experienced colorectal surgeon who was blinded to all other data. The sensitivity, specificity, negative predictive value, and positive predictive value of 3D‐EAUS in the diagnosis of OASI was evaluated. The trial is registered at ISCRTN: 18006769. Results A total of 680 scans were performed, of which 18.5% were judged as “non‐assessable”, resulting in 554 assessable recordings. Sphincter defects were observed in 12.8% of all assessable recordings on 3D‐EAUS (n = 71). With clinical examination set as the reference standard, ultrasound sensitivity in the diagnosis of OASI was 30.4%, whereas its specificity was 87.9%. The negative predictive value was 96.7% and the positive predictive value was only 9.9%. Comments were left on 175 examinations, of which 74% referred to the management of the examination. Conclusions Using 3D‐EAUS in a maternity ward is demanding because staff generally have little experience in endoanal ultrasound, which contributes to difficulties in obtaining good image quality. When 3D‐EAUS is performed to mirror screening settings, it adds no convincing diagnostic power to clinical examination in the diagnosis of OASI.

Background: Few studies have investigated women’s experiences of daily life after childbirth complicated by obstetric anal sphincter injury (OASI). The aim of the present study was to explore experiences related to recovery, sexual function, relationships and coping strategies among women affected by OASI. Methods: In-depth interviews were conducted using a purposive sample of 11 women affected by OASI. Women were interviewed 1-2 years after their first childbirth. Inductive qualitative content analysis was applied.Results: The theme “From hell to healed” illustrates women’s experiences of recovery, relationships and sexual function after OASI. Three categories addressing women’s perceptions emerged: “Challenged to the core”, “At the mercy of the care provider” and “For better or for worse”. Support from partners and family and comprehensive care were important elements for the experiences of coping and healing from OASI. Elements that negatively influenced women’s experiences were the pain and physical symptoms of pelvic floor dysfunction, normalization of symptoms by heath care providers, and unrealistic expectations about how this period in life should be experienced.Conclusions: OASI greatly affects women’s experiences of their first years with their newborn child, relationships, social context and sexuality. For some women, OASI negatively affects everyday life for a long period after childbirth. However, others heal and cope quite quickly. Health care professionals need to identify and pay attention to women with persisting problems after OASI so that they can be directed to the right level of care.
