Risk of urinary incontinence after childbirth: a 10-year prospective cohort study

OBJECTIVE: To estimate prospectively the effect of first delivery on subjective bladder function and to assess the influence of subsequent deliveries and obstetric events METHODS: We performed a prospective, observational cohort study. During a 10-week period in 1995, 304 of 309 eligible primiparous women (98%) entered the study at the postpartum maternity ward and completed a bladder function questionnaire. The 10-year observational period was completed by 246 of 304 subjects (81%). RESULTS: Prevalence of moderate-severe stress urinary incontinence increased from 5 of 304 subjects (2%) at baseline to 27 of 229 (12%) at 10 years follow-up (P < .001). Prevalence of moderate-severe urinary urgency increased from 0 subjects (0%) at baseline to 31 of 229 (13%) at the 10-year follow-up (P < .001). The relative risk (RR) (adjusted for maternal age and parity) of moderate to severe urinary incontinence increased significantly 10 years after first delivery (RR 5.8, 95% confidence interval [CI] 1.2-33.7). At multivariable analysis adjusted for age and parity, stress urinary incontinence symptoms at 9 months and 5 years follow-up were independently associated with the presence of symptoms at 10 years after index delivery (RR 13.3, 95% CI 3.9-33.1 and RR 14.1, 95% CI 2.5-18.8, respectively). Number of vaginal deliveries or other obstetric covariates did not affect the risk of stress urinary incontinence or urinary urgency. CONCLUSION: Vaginal delivery is independently associated with a significant long-term increase in stress urinary incontinence symptoms, as well as urinary urgency, regardless of maternal age or number of deliveries. LEVEL OF EVIDENCE: II-2.     

Anal incontinence after vaginal delivery: a five-year prospective cohort study

OBJECTIVE: The long-term prevalence of anal incontinence after vaginal delivery is unknown. The aim of the present study was to evaluate the prevalence of anal incontinence in primiparous women 5 years after their first delivery and to evaluate the influence of subsequent childbirth. METHODS: A total of 349 nulliparous women were prospectively followed up with questionnaires before pregnancy, at 5 and 9 months, and 5 years after delivery. A total of 242 women completed all questionnaires. Women with sphincter tear at their first delivery were compared with women without such injury. Risk factors for development of anal incontinence were also analyzed. RESULTS: Anal incontinence increased significantly during the study period. Among women with sphincter tears, 44% reported anal incontinence at 9 months and 53% at 5 years (P = .002). Twenty-five percent of women without a sphincter tear reported anal incontinence at 9 months and 32% had symptoms at 5 years (P < .001). Risk factors for anal incontinence at 5 years were age (odds ratio [OR] 1.1; 95% confidence interval [CI] 1.0-1.2), sphincter tear (OR 2.3; 95% CI 1.1-5.0), and subsequent childbirth (OR 2.4; 95% CI 1.1-5.6). As a predictor of anal incontinence at 5 years after the first delivery, anal incontinence at both 5 months (OR 3.8; 95% CI 2.0-7.3) and 9 months (OR 4.3; 95% CI 2.2-8.2) was identified. Among women with symptoms, the majority had infrequent incontinence to flatus, whereas fecal incontinence was rare. CONCLUSION: Anal incontinence among primiparous women increases over time and is affected by further childbirth. Anal incontinence at 9 months postpartum is an important predictor of persisting symptoms.     

非脱垂全子宫切除术后尿失禁发病率及危险因素——7年回顾性队列研究

目的:观察因非脱垂良性疾病行全子宫切除术对患者泌尿功能的长期影响,并探讨术后尿失禁(UI)的发生率及其危险因素。方法:选取2003年1月至2013年1月在北京协和医院因非子宫脱垂良性疾病(术前均无UI及脱垂,术后病理结果证实)行全子宫切除术或非子宫切除术者共560例,其中行全子宫切除术者384例,非子宫切除术者176例(对照组)。分别进行电话问卷随访,通过中文验证版女性下尿路症状国际尿失禁标准问卷(ICIQ-FLUTS)及尿道疾病程度分类问卷(UDI-6)完成术前、术后1年、3年、5年、7年的主观泌尿功能评价调查,观察术前无脱垂或尿失禁患者术后尿失禁的患病情况。结果:264例患者有效完成问卷,其中全子宫切术组164例(62.1%),对照组100例(37.9%)。术后1年时,全子宫切除术组的UI患病率显著高于对照组(P=0.031),而长期随访发现两者并无显著差异(P0.05)。术后1年、3年、5年和7年,全子宫切除组患者的UI患病率分别为8.5%(14/164)、9.7%(10/103)、12.2%(10/82)和16.7%(10/60)。全子宫切术组的压力性尿失禁(SUI)、急迫性尿失禁(UUI)等症状的术后患病率均明显高于对照组;急迫性尿失禁较压力性尿失禁常见。多因素分析发现,多产为UI发生的独立危险因素(OR=3.87,95%CI为1.12~13.33)。结论:全子宫切除术增加术后UI的短期发病风险,以急迫性尿失禁为主,长期尿失禁患病率随随访年限延长逐渐升高,产次为其发病的独立危险因素。     

Predictors of urinary incontinence in a prospective cohort of postmenopausal women

OBJECTIVE: To prospectively assess risk factors associated with occurrence of urinary incontinence among postmenopausal women. METHODS: We followed up 1,017 postmenopausal health maintenance organization enrollees, aged 55 to 75 years, for 2 years. The primary outcome measures were any urinary incontinence and severe incontinence reported at 12- or 24-month follow-up visits. RESULTS: Baseline prevalence of any amount or frequency of urinary incontinence in the past year was 66%. Among the 345 women without incontinence at baseline, 65 (19%) at 1 year and 66 (19%) at 2 years reported any incontinence. Ninety-two of 672 (14%) and 96 of 672 (14%) women with incontinence at baseline reported no incontinence at years 1 and 2. In an adjusted multiple logistic regression model, independent predictors of any incontinence included white race (odds ratio [OR] 1.7, 95% confidence interval [CI] 1.1-2.6), vaginal estrogen cream (OR 2.0, CI 1.1-3.7), vaginal dryness (OR 1.6, CI 1.2-2.2), vaginal discharge (OR 1.5, CI 1.0-2.2), 6 or more lifetime urinary tract infections (OR 1.8, CI 1.2-2.6), and diabetic peripheral neuropathy (OR 1.7, CI 1.0-3.1). In adjusted models, predictors of severe incontinence were history of hysterectomy (OR 1.8, CI 1.1-2.7) and any vaginal symptom (OR 1.7, CI 1.0-2.8). CONCLUSION: A substantial proportion of incontinence-free postmenopausal women developed urinary incontinence during 2 years of follow-up. Because vaginal symptoms are associated with urinary incontinence, their relationship with other risk factors, including vaginal Escherichia coli colonization and vaginal estrogen cream use, warrant additional study. Similarly, diabetic peripheral neuropathy and hysterectomy associations suggest areas for future investigation. LEVEL OF EVIDENCE: II-2.     

Effects of carrying a pregnancy and of method of delivery on urinary incontinence: a prospective cohort study

BACKGROUND: This study was carried out to identify risk factors associated with urinary incontinence in women three months after giving birth. METHODS: Urinary incontinence before and during pregnancy was assessed at study enrolment early in the third trimester. Incontinence was re-assessed three months postpartum. Logistic regression analysis was used to assess the role of maternal and obstetric factors in causing postpartum urinary incontinence. This prospective cohort study in 949 pregnant women in Quebec, Canada was nested within a randomised controlled trial of prenatal perineal massage. RESULTS: Postpartum urinary incontinence was increased with prepregnancy incontinence (adjusted odds ratio [adj0R] 6.44, 95% CI 4.15, 9.98), incontinence beginning during pregnancy (adjOR 1.93, 95% CI 1.32, 2.83), and higher prepregnancy body mass index (adjOR 1.07/unit of BMI, 95% CI 1.03,1.11). Caesarean section was highly protective (adjOR 0.27, 95% CI 0.14, 0.50). While there was a trend towards increasing incontinence with forceps delivery (adjOR 1.73, 95% CI 0.96, 3.13) this was not statistically significant. The weight of the baby, episiotomy, the length of the second stage of labour, and epidural analgesia were not predictive of urinary incontinence. Nor was prenatal perineal massage, the randomised controlled trial intervention. When the analysis was limited to women having their first vaginal birth, the same risk factors were important, with similar adjusted odds ratios. CONCLUSIONS: Urinary incontinence during pregnancy is extremely common, affecting over half of pregnant women. Urinary incontinence beginning during pregnancy roughly doubles the likelihood of urinary incontinence at 3 months postpartum, regardless whether delivery is vaginal or by Caesarean section.     

Mode of childbirth and neonatal outcome after external cephalic version: A prospective cohort study

Objectiveto assess the mode of childbirth and adverse neonatal outcomes in women with a breech presentation with or without an external cephalic version attempt, and to compare the mode of childbirth among women with successful ECV to women with a spontaneous cephalic presentation.Designprospective matched cohort study.Setting25 clusters (hospitals and its referring midwifery practices) in the Netherlands. Data of the Netherlands perinatal registry for the matched cohort.Participantssingleton pregnancies from January 2011 to August 2012 with a fetus in breech presentation and a childbirth from 36 weeks gestation onwards. Spontaneous cephalic presentations (selected from national registry 2009 and 2010) were matched in a 2:1 ratio to cephalic presentations after a successful version attempt. Matching criteria were maternal age, parity, gestational age at childbirth and fetal gender. Main outcomes were mode of childbirth and neonatal outcomes.Measurements and findingsof 1613 women eligible for external cephalic version, 1169 (72.5%) received an ECV attempt. The overall caesarean childbirth rate was significantly lower compared to women who did not receive a version attempt (57% versus 87%; RR 0.66 (0.62–0.70)). Women with a cephalic presentation after ECV compared to women with a spontaneous cephalic presentation had a decreased risk for instrumental vaginal childbirth (RR 0.52 (95% CI 0.29–0.94)) and an increased risk of overall caesarean childbirth (RR 1.7 (95%CI 1.2–2.5)).Key conclusionswomen who had a successful ECV are at increased risk for a caesarean childbirth but overall, ECV is an important tool to reduce the caesarean rate.Implication for practiceECV is an important tool to reduce the caesarean section rates.     

Recurrence of stress urinary incontinence after tension-free vaginal tape and childbirth

Retropubic or transobturator insertions of suburethral tapes are the new gold standard surgical procedure for female stress urinary incontinence. Some women of childbearing age can be treated by a suburethral tape. There are at present no sufficient data to recommend a mode of delivery rather than another in these patients. We report the case of a young woman, cured of her urinary incontinence by a suburethral tape. A recurrence occurred after childbirth by vaginal route. A second suburethral tape made it possible to restore the continence. The patient became again pregnant. A preventive caesarean section was quite as ineffective to preserve the continence.     

Faecal incontinence after childbirth

Objective To measure the prevalence and severity of postpartum faecal incontinence, especially new incontinence, and to identify obstetric risk factors.
Design A cohort study with information on symptoms collected in home-based interviews and obstetric data from hospital casenotes.
Setting Deliveries from a maternity hospital in Birmingham.
Participants Nine hundred and six women interviewed a mean of 10 months after delivery.
Main outcome measures New faecal incontinence starting after the birth, including frank incontinence, soiling and urgency.
Results Thirty-six women (4%) developed new faecal incontinence after the index birth, 22 of whom had unresolved symptoms. Twenty-seven had symptoms several times a week, yet only five consulted a doctor. Among vaginal deliveries, forceps and vacuum extraction were the only independent risk factors: 12 (33%) of those with new incontinence had an instrumental delivery compared with 114 (14%) of the 847 women who had never had faecal incontinence. Six of those with incontinence had an emergency caesarean section but none became incontinent after elective sections.
Conclusions Faecal incontinence as an immediate consequence of childbirth is more common than previously realised, and medical attention is rarely sought. Forceps and vacuum extraction deliveries are risk factors, with no protection demonstrated from emergency caesarean section. Identification and treatment is a priority.     

Etiology of stillbirth at term: a 10-year cohort study

Objective. To examine etiological factors contributing to cases of intrauterine fetal demise in term pregnancies over a 10-year period.

Methods. This was a retrospective cohort analysis of 29 908 term (37⁺⁰ to 41⁺⁶ weeks gestation) infants delivering in a single tertiary-referral university institution over the 10-year period from 1996 to 2005. Cases of stillbirth were identified from a computerized hospital database, and pathological, clinical, and biochemical data were reviewed for all cases. Trends were analyzed using the Cusick test for trend. Categorical data were analyzed using the Fisher's exact test, with the 5% level considered significant.

Results. The incidence of intrauterine fetal demise at term was 1.8 per 1000 at-risk pregnancies. There was no significant downward trend in the rate of term stillbirth between 1996 and 2005 (p = 0.0808). Stillbirths were unexplained in 51% of cases, although in many cases a possible etiological factor was identified but not necessarily proven. There was a significant downward trend in the incidence of unexplained term stillbirths at our institution over the 10-year study period (p = 0.0105). Placental/cord factors accounted for 25% of term stillbirths and did not decrease significantly over the study period (p = 0.0953). Almost 50% of term stillbirths occurred in women who registered late or had no antenatal care. However, suboptimal antenatal care was not predictive of differences in either acceptance of perinatal postmortem or successful identification of stillbirth etiology.

Conclusions. The incidence of stillbirth at term is 2 per 1000 term pregnancies and has not changed significantly in the past 10 years. Almost 50% of term stillbirths occurred in women with suboptimal antenatal care. More than half of cases are unexplained, often resulting from an incomplete diagnostic work-up. Despite this, there has been a significant downward trend in the rates of unexplained stillbirth at term. It is imperative that a complete diagnostic work-up is performed in cases of term stillbirth, to minimize the incidence of unexplained stillbirth.     

Psychological growth after childbirth: an exploratory prospective study

Introduction: It is important to elucidate the psychologically positive aspects of childbirth for mothers, and not only the negative aspects such as perinatal depression. This study aimed to examine psychological growth after childbirth and its related variables by focussing on five factors of posttraumatic growth: relating to others, new possibilities, personal strength, spiritual change and appreciation of life.

Methods: Pregnant women during mid-pregnancy were consecutively recruited at a women’s hospital in Japan and followed up 1 month after childbirth. Psychological growth was assessed by the Posttraumatic Growth Inventory.

Results: Among 177 participants, 117 (66.1%) completed follow-up assessments 1 month after childbirth. Multivariable regression analysis revealed that primipara, higher resilience and less fear at childbirth were associated with posttraumatic growth factors of relating to others and new possibilities. High resilience and less fear at childbirth were also associated with personal strength. On the other hand, being primiparous and high depressive symptoms were associated with greater appreciation of life. No variables were associated with spiritual change.

Discussion: These findings suggest that giving birth for the first time could be a highly challenging life event as well as an opportunity which leads to PTG, and that giving birth with low fear might lead to mothers’ psychological growth. On the other hand, appreciation of life might need attention as it might signify some sorts of coping response. These findings contribute to our understanding of the psychological changes experienced by mothers.     

Risk factors for cervical intraepithelial neoplasia recurrence after conization: a 10-year study

Objective

To evaluate the risk factors potentially involved in the development of cervical intraepithelial neoplasia (CIN) recurrence after cervical conization in a long-term follow-up period.

Study design

Consecutive patients with histologically proven CIN who had undergone either cold knife conization or a loop electrosurgical excision procedure were enrolled and scheduled for serial follow-up examinations over a 10-year period. Data were stored in a digital database. Multivariate analysis was performed to identify factors for recurrence.

Results

Between January 1999 and December 2009, 282 patients fulfilled the inclusion criteria and were included in the final statistical analysis. After a median follow-up of 26.7 months (range 6–100), 64 (22.7%) women developed histologically confirmed recurrence. The 2-year recurrence-free survival was 83.7% and 66.7% for women with negative and positive margins, respectively (p = 0.008). The 5-year recurrence-free survival was 75.4% and 50.3% for patients with negative and positive margins, respectively (p = 0.0004). Positive surgical margin was the most important independent predictor of recurrence [HR 2.5 (95%CI 1.5–4.5), p = 0.0007; Wald 11.338]. After multinomial logistic regression the indication for conization based on persistent CIN1 was the only independent predictor for negative margin [OR 0.3 (95%CI 0.1–0.7), p = 0.008].

Conclusions

Our study demonstrated that the surgical margin status represents the most important predictor for CIN recurrence after conization. After excisional therapy, close follow-up is mandatory for the early detection of recurrent disease. The identification of risk factors for recurrence may guide clinical decision-making on expectant management versus re-intervention.     

Stress urinary incontinence 4 years after the first delivery: a retrospective cohort survey

BACKGROUND: Our aim was to estimate the prevalence of stress urinary incontinence 4 years after the first delivery and analyze its risk factors. METHODS: A retrospective cohort survey was conducted in a French university hospital. The 669 primiparous women who delivered in our department in 1996 a singleton in a vertex position between 37 and 41 weeks of amenorrhea were included. A mailed questionnaire was sent 4 years after the indexed delivery. The main outcome measure was stress urinary incontinence 4 years after the first delivery. RESULTS: Three hundred and seven women replied, 274 had moved and 88 did not respond. Four years after the first delivery, prevalence of stress urinary incontinence was 29% (89/307). According to multiple logistic regression analysis, the independent risk factors were urine leakage before the first pregnancy [odds ratio (OR) 18.7; 95% confidence interval (CI) 3.6-96.4], urine leakage during the first pregnancy (OR 2.5; 95% CI 1.3-4.8), duration of first labor > or = 8 h (OR 3.1; 95% CI 1.7-5.7), mother's age > 30 years at the first delivery (OR 2.4; 95% CI 1.4-4.2) and cesarean section at the first delivery (OR 0.3; 95% CI 0.1-0.9). CONCLUSION: Our results suggest that stress urinary incontinence after pregnancy arises from a multifactorial condition. The main risk factors are: age, previous incontinence (before or during the first pregnancy), prolonged labor and vaginal delivery.     

Colposuspension after previous failed incontinence surgery: a prospective observational study

Objective To evaluate the outcome of colposuspension for genuine stress incontinence in women who had previously undergone bladder neck surgery.
Design Prospective observational study.
Setting Tertiary referral urogynaecology unit.
Participants Fifty-two consecutive women with recurrent genuine stress incontinence operated on one surgeon.
Main outcome measures Subjective and objective cure of stress incontinence. Complications one surgeon.
Results The mean age of the women was 51 years (range 28–72) and weight 72.7 kg (range 53–112). Sixty-five continence procedures had been performed previously, with 13 women (25%) having had more than one operation. Nine months post-operatively the subjective cure rate was 80% and objective cure rate 78%. Intraoperative complications were few but included two bladder injuries and one rectus muscle tear which required repair. Seven women (13%) developed voiding difficulties which required clean intermittent self-catheterisation, but only one needed to continue this for six months. None of the women developed detrusor instability.
Conclusions In this setting colposuspension after previous bladder neck surgery offers a high rate of success. However, long term follow up is needed to see if this effect is maintained.     

Sexual function after childbirth by the mode of delivery: a prospective study

Purpose

The objective of the present study was to evaluate sexual behavior longitudinally in the postpartum period by mode of delivery.

Methods

In this prospective study, five groups were defined: women who delivered vaginally without an episiotomy (n = 16), women who delivered vaginally with an episiotomy (n = 14), women who delivered by instrumental delivery (n = 16), women who delivered by an emergent cesarean section (n = 19), and women who delivered by an elective cesarean section (n = 17). Sexual behavior was assessed by the female sexual function index (FSFI) questionnaire at 6, 12, and 24 weeks postpartum and by the timing of resumption of sexual intercourse.

Results

The mean ± SD self-reported timing of resumption of sexual activity was 4.5 ± 1.8, 7.9 ± 3.0, 7.3 ± 3.4, 6.1 ± 2.6, and 6.1 ± 2.4 weeks in the vaginal delivery without an episiotomy group, in the vaginal delivery with an episiotomy group, in the instrumental delivery group, in the elective cesarean delivery group, and in the emergent cesarean delivery group, respectively (p = 0.013). The FSFI total score in the entire study group (n = 82) was 14.1 ± 10.8, 24.6 ± 7.6, and 27.7 ± 5.1 at 6, 12, and 24 weeks postpartum, respectively (p < 0.05). The FSFI total score did not differ significantly across types of mode of delivery at 6, 12, or 24 weeks postpartum.

Conclusion

The significance by delivery mode difference in the postpartum resumption of sexual activity was not accompanied by difference in sexual function scores. Specifically, elective cesarean delivery was not associated with a protective effect on sexual function after childbirth.
