BACKGROUND Obstetric anal sphincter injuries (OASIS) are associated with sexual dysfunction and a lower likelihood of sexual activity in the postpartum period. The aim of the present study was to compare coital resumption and the variables influencing this activity after delivery in women with and without a history of obstetric anal sphincter injury (OASIS) and according to the mode of delivery. METHODS A prospective, observational, case-control study was performed at 6 months postpartum in 318 women: 140 with a history of primary repaired OASIS and 178 women without OASIS. Demographic and obstetric data, breastfeeding, and symptoms of urinary and anal incontinence were collected. Patients were asked about coital resumption and completed the validated specific Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12). Continuous and non-continuous variables were compared using ANOVA and the Fisher exact tests, respectively. A multivariate logistic regression model and a multiple regression analysis were constructed to assess the impact of demographic and clinical variables on the percentage of coital resumption and on the PISQ-12 score, respectively. RESULTS After a spontaneous delivery (SD), patients without OASIS showed a higher percentage of coital resumption than those with OASIS (98% vs. 77%; p = 0.003), and the PISQ-12 score was also higher (p < 0.001). PISQ-12 score was better in women with SD compared to those with operative vaginal delivery (OVD)(p < 0.001), independently of the history of OASIS. Current breastfeeding, a higher Wexner score and OVD negatively influenced the PISQ-12 score. CONCLUSIONS After SD, women with OASIS resumed coital activity later than women without OASIS. Women with OVD resumed coital activity later, and had a lower PISQ-12 score than women with SD.

OASIS患者分娩后恢复原状：工具分娩和自发分娩之间的差异。

背景技术产后肛门括约肌损伤（OASIS）与性功能障碍和产后性活动可能性降低相关。本研究的目的是根据分娩方式比较有无肛门产妇括约肌损伤史（OASIS）的妇女分娩后的恢复性功能和影响分娩后活动的变量。方法对产后6个月的318例妇女进行了一项前瞻性，观察性病例对照研究：140例有原发性OASIS病史的患者和178例无OASIS病史的妇女。收集人口统计学和产科数据，母乳喂养以及尿失禁和肛门失禁的症状。向患者询问是否恢复性交，并完成经过验证的特定盆腔器官脱垂/尿失禁性问卷12（PISQ-12）。分别使用ANOVA和Fisher精确检验比较了连续变量和非连续变量。构建了多元逻辑回归模型和多元回归分析以分别评估人口统计学和临床​​变量对恢复性行为的百分比和对PISQ-12评分的影响。结果自发分娩（SD）后，没有OASIS的患者表现出的恢复性交的百分比高于有OASIS的患者（98％比77％； p = 0.003），而PISQ-12评分也更高（p <0.001） 。独立于OASIS病史，SD患者的PISQ-12评分要优于手术阴道分娩（OVD）的患者（p <0.001）。当前的母乳喂养，较高的韦克斯纳评分和OVD对PISQ-12评分产生负面影响。结论SD之后，患有OASIS的女性比没有OASIS的女性恢复性交的时间晚。OVD妇女较晚恢复性活动，且PISQ-12得分低于SD妇女。
