Incidence and cause of postpartum urinary stress incontinence.

Urinary leakage was reported in 53.5% of our patients at least once during pregnancy. Multigravidae and women older than 30 were affected more often than primigravidae or women younger than 30. 6.2% of all women, who were continent before pregnancy, developed permanent stress incontinence after vaginal delivery. As a conclusion, it can be said, that vaginal delivery itself predisposes for permanent stress urinary incontinence (SUI). Factors, which increase the trauma to the pelvic floor (tear, no episiotomy, forceps or vacuum extraction), show a higher incidence of postpartum persisting SUI without statistic significance. Labour management with epidural anaesthesia showed a statistically proven lower incidence of postpartum persisting SUI in comparison to the pudendal block.     

Risk of postpartum urinary incontinence associated with pregnancy and mode of delivery

AIM: The aim was to estimate the postpartum urinary incontinence (PP UI) impact of precursory UI during pregnancy (PR UI) and delivery performed by cesarean section (CS) vs. vaginal childbirth (VC). METHODS: Among the members of two population samples, in total 8610 women aged 20-59 years, 1232 had their first childbirth and 642 their second childbirth within 13-120 months prior to responding to a questionnaire that included information on PR UI occurrence, mode of delivery and PP UI occurrence. RESULTS: CS was applied in 12.2% of first childbirths, and 87.8% thus delivered vaginally; PR UI during the pregnancy leading to the first childbirth was reported by 15.6%, and a total of 26.3% reported PP UI. An increased PP UI occurrence was reported following VC (28.3% vs. 12.0% in women undergoing CS, p < 0.001) and after PR UI (first childbirth, 66.7% vs. 18.8% in women not reporting PR UI, p < 0.0001). Among cases of PP UI following the first childbirth, 56.1% and 69.5% of cases could be attributed to PR UI and VC, respectively. CONCLUSIONS: The highest PP UI risks were found among women complaining of PR UI, which manifested itself as a crucial, independent precursor of PP UI. Because of the high frequency of VC, more than seven out of 10 cases of UI following the first childbirth, however, seemed to be attributable to VC. The present data did not lend significant support to the assumption that the PP UI risk is also lowered after a subsequent delivery by CS.     

Female urinary incontinence during pregnancy and after delivery: Clinical impact and contributing factors

Urinary incontinence (UI) is a common condition affecting adult women of all ages and it could have a negative influence on quality of life. The etiology of UI is multifactorial, but some of the most important risk factors are obesity and ageing, as well as adverse obstetric events. Pregnancy and delivery per se have been implicated in the etiology of UI. Although several studies have demonstrated a direct association between UI and vaginal delivery in short, medium and long-term, the role of childbirth on the risk of UI remains controversial. The mechanical strain during delivery may induce injuries to the muscle, connective and neural structures. Vaginal birth can be associated with relaxation or disruption of fascial and ligamentous supports of pelvic organs. Parity, instrumental delivery, prolonged labor and increased birth weights have always been considered risk factors for pelvic floor injury. Also genetic factors have been recently raised up but still there are not appropriate guidelines or measures to reduce significantly the incidence of UI. The role of pelvic floor muscle training (PFMT) in the prevention and treatment of UI is still unclear. However, PFMT seems to be useful when supervised training is conducted and it could be incorporated as a routine part of women’s exercise programmes during pregnancy and after childbirth.     

The prevalence of fecal incontinence and urinary incontinence in primiparous postpartum Chinese women

Objective

This study investigated the prevalence of fecal incontinence (FI) and urinary incontinence (UI) in primiparous postpartum Chinese women.

Study design

Questionnaires about FI and UI symptoms were completed via telephone interviews conducted within 6 months postpartum.

Results

A total of 1889 primiparous postpartum women were asked to participate in this investigation. Only 13 (0.69%) of them had FI within 6 months after parturition, including loss of flatus in six women (0.32%), loss of solid stool in one (0.05%), loss of liquid stool in two (0.11%) and fecal urgency in four (0.21%). Bivariate logistic regression analysis showed that FI was significantly associated with forceps delivery OR = 37.91 (95% CI 4.20-342.18, P = 0.001) and medio-lateral episiotomy OR = 11.79 (95% CI 1.47-94.46, P = 0.02). The prevalence of UI, stress urinary incontinence (SUI), urge urinary incontinence (UUI) and mixed urinary incontinence (MUI) was 9.9% (186), 8.0% (151), 1.0% (18) and 0.9% (17), respectively. Multinomial logistic regression analysis found that SUI prevalence was related to age OR = 1.08 (95% CI 1.04-1.12, P = 0.000), maternal weight OR = 1.04 (95% CI 1.02-1.06, P = 0.001), neonate head circumference OR = 1.17 (95% CI 1.01-1.36, P = 0.043), spontaneous labor OR = 5.42 (95% CI 2.60-11.32, P = 0.000), forceps delivery OR = 7.0 (95% CI 2.40-20.41, P = 0.000), and medio-lateral episiotomy OR = 5.24 (95% CI 3.15-8.72, P = 0.000).

Conclusions

1. FI and UI prevalence was lower in our department than reported in previous studies in other areas. 2. Vaginal delivery has a risk impact on women's FI and UI, especially forceps delivery and medio-lateral episiotomy. 3. Maternal age, weight, newborn head circumference, spontaneous vaginal delivery, forceps delivery, and medio-lateral episiotomy increase the risk of UI.     

Prevalence of urinary incontinence and other urological problems during pregnancy: a questionnaire based study

Objective  To find out the prevalence of various urological symptoms in pregnant women, the status before pregnancy, and their perceived impact. Methods  A questionnaire incorporating various urological problems was prepared and used over 240 pregnant women to know their prevalence in different trimesters of pregnancy and compare them with prevalence before pregnancy. Results  Increased urinary frequency (>10/day) (40.8 vs. 3.8%), nocturia (72.9 vs. 50.6%), burning micturition (21.3 vs. 3.8%), UTI (4.6 vs. 1.6%), urinary hesitancy (14.6 vs. 1.6%), urinary incontinence (25.8 vs. 8.2%) and botheration (22.1 vs. 2.7%) were seen during and before pregnancy, respectively. These also show an increment with advancement of gestation. Urinary incontinence was seen more often with advancing age and parity. Conclusion  There is a very high prevalence of urological symptoms during pregnancy as compared to before pregnancy.     

Mixed urinary incontinence symptoms: urodynamic findings,incontinence severity,and treatment response

OBJECTIVE: To investigate the relationship between the symptom of mixed urinary incontinence and incontinence severity, urodynamic findings, and treatment response. METHODS: This is a secondary analysis of data from 553 women randomized into a double-blind, placebo-controlled study evaluating duloxetine (serotonin-norepinephrine reuptake inhibitor) for the treatment of predominant stress urinary incontinence. Assessment variables included incontinent episode frequency, the Incontinence Quality of Life Questionnaire (I-QOL), and the Patient Global Impression of Severity Scale (PGI-S). Urge symptoms were identified with three urge I-QOL questions not included in corrected I-QOL calculations. RESULTS: At baseline, 171 women (31%) had mixed urinary incontinence. They had more severe baseline urinary incontinence than did those with stress urinary incontinence (mean incontinent episode frequency 14.3 versus 10.5; PGI-S normal or mild 26.5% versus 70.4%; mean corrected I-QOL 59.1 versus 79.9; all Ps <.001). Baseline urodynamics were performed on a subset of 86 women. Subjects with both urodynamic stress incontinence and detrusor overactivity had less severe incontinence compared with subjects with only urodynamic stress incontinence. Both mixed urinary incontinence and stress urinary incontinence groups had significant decreases in median incontinent episode frequency at a 40 mg per day (62% and 58%, respectively) and 80 mg per day (63% and 65%) duloxetine dose compared with placebo (33% and 44%; all Ps <.05). Response was not dependent on the type of symptoms (interaction P =.47). CONCLUSION: For women presenting with predominant stress urinary incontinence symptoms, the major determinant of concurrent urge symptoms was incontinence severity and not the pathophysiologic condition(s) causing the incontinence; duloxetine demonstrated equal efficacy for women with mixed urinary incontinence and pure stress urinary incontinence.

孕期妇女盆底肌张力变化及压力性尿失禁的研究

目的通过调查孕期妇女压力性尿失禁（stress urinary incontinence，SUI）的发病情况，测定各孕期妇女盆底肌张力，分析孕期尿失禁发病的相关因素及盆底肌训练的作用，以便寻求更好的预防孕期与产后尿失禁的时机和方法。方法选取2005年1月至4月间常规孕期检查而未进行过盆底肌训练的健康初产妇为研究对象，分为三组：第1组孕11～周；第2组孕18～周；第3组孕28～37周。调查SUI的发病情况、测量盆底肌张力值，并选取部分孕妇行盆底肌锻炼，定期随访。对各组孕妇的盆底肌张力值和尿失禁的发病情况进行统计分析。结果纳入研究的孕妇共374例，三组不同程度SUI的发病率依次为12．8％、24．0％、32．0％，盆底肌张力的活力均值和做功均值随孕周增加而逐渐降低。第1组盆底肌张力的做功值与孕前BMI呈负相关（r=-0．185，P=0．046），孕前进行一般体育锻炼者的盆底肌张力活力值大于不锻炼者（15．35±10．01和12．19±5．59，P=0．033）。第3组有SUI者的产时BMI大于无尿失禁者（20．91±2．97和20．04±1．59，P=0．012）。部分孕妇进行盆底肌锻炼，孕37周随访，锻炼组的尿失禁发病率低于不锻炼组（22．2％和5．6％，P〈0．01）；锻炼组的盆底肌张力活力值和做功值大于不锻炼组（P〈0．001，P〈0．05）。结论孕期妇女SUI发病率随孕周增加而逐渐增加，而盆底肌张力值逐渐下降。孕前体育锻炼可以增加盆底组织的弹性和收缩能力。孕前BMI越大盆底肌的支持力和耐力越弱。尿失禁者的产时BMI大于无尿失禁者。盆底肌锻炼者可能对尿失禁发病率有预防作用。     

Thrombosis during pregnancy and the postpartum period

OBJECTIVE: To describe the circumstances surrounding deep vein thrombosis among pregnant or postpartum patients enrolled in a large multicenter registry. STUDY DESIGN: Consecutive patients with ultrasound-confirmed deep vein thrombosis were enrolled at 183 institutions during a 6-month period from October 2001 to March 2002. Fifty-three who were either pregnant or within 6 weeks postpartum were analyzed. RESULTS: Thirty-four were pregnant and 19 were postpartum. Among those pregnant, 44% experienced deep vein thrombosis in the first trimester, 24% in the second, and 26% in the third. Deep vein thrombosis occurred in the left lower extremity in 76% of the pregnant and 47% of the postpartum women. Four pregnant and 2 postpartum women had pelvic vein thrombosis. Among those postpartum, 74% had undergone surgery within 3 months. CONCLUSION: During pregnancy, the risk of deep vein thrombosis begins in the first trimester. Thus, we believe that when prophylaxis is indicated, it should be initiated early in gestation.     

Sexual health during pregnancy and the postpartum

IntroductionPregnancy and childbirth is a special period in a woman's life, which involves significant physical, hormonal, psychological, social, and cultural changes that may influence her own sexuality as well as the health of a couple's sexual relationship.AimTo comprehensively review the literature on the effects of pregnancy and the postpartum period on a couple's sexual health and well-being.Main Outcome MeasuresEvidence from the published literature of the impact of pregnancy, childbirth, and the postpartum period on sexual function.MethodsMedline and PubMed search for relevant publications on the effects of pregnancy and childbirth on sexual health and function, with particular focus on the physical, hormonal, psychological, social, and cultural changes that may occur during the antepartum, intrapartum, and postpartum period.ResultsDespite fears and myths about sexual activity during pregnancy, maintaining a couple's sexual interactions throughout pregnancy and the postpartum period can promote sexual health and well-being and a greater depth of intimacy.ConclusionsClinicians must seek to engage in an open discussion and provide anticipatory guidance for the couple on expected changes in sexual health as well as promote the design of rigorous, evidence-based studies to further elucidate our understanding of sexual function during pregnancy and the postpartum.

Exercise during pregnancy and the postpartum period

The physiologic and morphologic changes of pregnancy may interfere with the ability to engage safely in some forms of physical activity. A woman's overall health, including obstetric and medical risks, should be evaluated before prescribing an exercise program. Generally, participation in a wide range of recreational activities appears to be safe during pregnancy; however, each sport should be reviewed individually for its potential risk, and activities with a high risk of falling or those with a high risk of abdominal trauma should be avoided during pregnancy. Scuba diving also should be avoided throughout pregnancy because the fetus is at an increased risk for decompression sickness during this activity. In the absence of either medical or obstetric complications, 30 minutes or more of moderate exercise a day on most, if not all, days of the week is recommended for pregnant women.     

Twenty-four hour pH monitoring during pregnancy and at postpartum: a preliminary study

OBJECTIVE: To quantify the amount of acid refluxed in symptomatic pregnant women and compare this to the postpartum period. METHODS: Eight non complicated symptomatic pregnant women were enrolled. The mean age was 28+/-6.3 years and gestational age 26+/-4.4 weeks at inclusion. Repeated measurements were done at 9.8+/-6.5 weeks postpartum. Esophageal manometry and 24h pH monitoring were performed at each time period. RESULTS: Heartburn (HB), regurgitation and dysphagia were the main presenting symptoms, however only regurgitation was significantly more frequent during pregnancy (P=0.01). Lower esophageal sphincter (LES) pressure was significantly lower during pregnancy (P=0.001). Twenty-four hour pH monitoring variables were worse and the number of reflux episodes and the upright reflux reached statistical significance (P=0.03, and 0.01, respectively). CONCLUSION: Pregnancy is associated with decreased LES pressure, more frequent episodes of reflux and upright reflux.     

Incidence of and risk factors for thromboembolism during pregnancy and postpartum: A 10-year nationwide population-based study

ObjectiveKnowledge of the incidence of pregnancy-related thromboembolism and its risk factors is clinically important because thromboembolism is the leading cause of maternal death. However, there are insufficient large population-based studies on this topic. The purpose of this study was to estimate the incidence of and identify the risk factors for thromboembolism during pregnancy and puerperium.Materials and methodsWe analyzed data from 2007 to 2016 using the Health Insurance Review and Assessment Service (HIRA) database. Women who gave birth in the Republic of Korea were identified. Thromboembolism was defined as the simultaneous presence of both the diagnostic and test codes. Risk factors for thromboembolism were identified using logistic regression.ResultsA total of 1,188 delivery episodes with thromboembolism were extracted from 4,243,393 delivery episodes. The incidence of thromboembolism was 0.28 per 1,000 deliveries, and it increased over the 10-year period. The incidence of antepartum thromboembolism was 0.1 per 1,000 deliveries (418 cases), and the incidence of postpartum thromboembolism was 0.18 per 1,000 deliveries (770 cases). Thromboembolism was associated with ovarian hyperstimulation syndrome, low socioeconomic status, multiple birth, cesarean birth, preeclampsia, postpartum hemorrhage, placenta previa, advanced maternal age, hyperemesis and primiparity. The factors associated with mortality from thromboembolism were cesarean birth and preterm premature rupture of membranes.ConclusionThe incidence of pregnancy-related thromboembolism increased over the 10-year study period. Low socioeconomic status, ovarian hyperstimulation syndrome, cesarean delivery and premature rupture of membranes were high-risk factors. This study provides an important reference for thromboprophylaxis for pregnancy-related thromboembolism.
