Planned cesarean section versus planned vaginal delivery: comparison of lower urinary tract symptoms.

We compared the prevalence and risk of lower urinary tract symptoms in healthy primiparous women in relation to vaginal birth or elective cesarean section 9 months after delivery. We performed a prospective controlled cohort study including 220 women delivered by elective cesarean section and 215 by vaginal birth. All subjects received an identical questionnaire on lower urinary tract symptoms in late pregnancy, at 3 and 9 months postpartum. Two hundred twenty subjects underwent elective cesarean section, and 215 subjects underwent vaginal delivery. After childbirth, the 3-month questionnaire was completed by 389/435 subjects (89%) and the 9-month questionnaire by 376/435 subjects (86%). In the vaginal delivery cohort, all lower urinary tract symptoms increased significantly at 9 months follow-up. When compared to cesarean section, the prevalence of stress urinary incontinence (SUI) after vaginal delivery was significantly increased both at 3 (p < 0.001) and 9 months (p = 0.001) follow-up. In a multivariable risk model, vaginal delivery was the only obstetrical predictor for SUI [relative risk (RR) 8.9, 95% confidence interval (CI) 1.9-42] and for urinary urgency (RR 7.3 95% CI 1.7-32) at 9 months follow-up. A history of SUI before pregnancy (OR 5.2, 95% CI 1.5-19) and at 3 months follow-up (OR 3.9, 95% CI 1.7-8.5) were independent predictors for SUI at 9 months follow-up. Vaginal delivery is associated with an increased risk for lower urinary tract symptoms 9 months after childbirth when compared to elective cesarean section.

Symptoms of anal and urinary incontinence following cesarean section or spontaneous vaginal delivery.

OBJECTIVE: The objective of the study was to compare the prevalence of incontinence disorders in relation with spontaneous vaginal delivery or cesarean section. STUDY DESIGN: Two hundred women with spontaneous vaginal deliveries only were compared with 195 women with cesarean deliveries only 10 years after first delivery. RESULTS: When compared with cesarean section, vaginal delivery was associated with an increased frequency of stress urinary incontinence (P = .006) and an increased use of protective pads (P = .008) as well as an increased frequency of fecal urgency (P = .048) and gas incontinence (P = .01). At multivariate regression analysis, mode of delivery showed no significant association with incontinence symptoms other than an increased risk for flatus incontinence in women with a history of obstetric anal sphincter injury (odds ratio 3.1; 95% confidence interval, 1.5 to 8.9). CONCLUSION: Incontinence symptoms are more common following spontaneous vaginal delivery when compared with cesarean section 10 years after first delivery. However, cesarean section is not associated with a major reduction of anal and urinary incontinence.

Anal sphincter lacerations and upright delivery postures--a risk analysis from a randomized controlled trial.

OBJECTIVE: To evaluate obstetric sphincter lacerations after a kneeling or sitting position at second stage of labor in a multivariate risk analysis model. MATERIALS AND METHODS: Two hundred and seventy-one primiparous women with normal pregnancies and spontaneous labor were randomized, 138 to a kneeling position and 133 to a sitting position. Medical data were retrieved from delivery charts and partograms. Risk factors were tested in a multivariate logistic regression model in a stepwise manner. RESULTS: The trial was completed by 106 subjects in the kneeling group and 112 subjects in the sitting group. There were no significant differences with regard to duration of second stage of labor or pre-trial maternal characteristics between the two groups. Obstetrical sphincter tears did not differ significantly between the two groups but an intact perineum was more common in the kneeling group (p<0.03) and episiotomy (mediolateral) was more common in the sitting group (p<0.05). Three grade IV sphincter lacerations occurred in the sitting group compared to none in the kneeling group (NS). Multivariate risk analysis indicated that prolonged duration of second stage of labor and episiotomy were associated with an increased risk of third- or fourth-degree sphincter tears (p<0.01 and p<0.05, respectively). Delivery posture, maternal age, fetal weight, use of oxytocin, and use of epidural analgesia did not increase the risk of obstetrical anal sphincter lacerations in the two upright postures. CONCLUSION: Obstetrical anal sphincter lacerations did not differ significantly between a kneeling or sitting upright delivery posture. Episiotomy was more common after a sitting delivery posture, which may be associated with an increased risk of anal sphincter lacerations. Upright delivery postures may be encouraged in healthy women with normal, full-term pregnancy.

Urinary incontinence after hysterectomy--three-year observational study.

OBJECTIVES: To perform a prospective evaluation of the long-term effects of hysterectomy on symptoms of urinary incontinence. METHODS: A prospective observational cohort study was performed. Preoperatively, 120 consecutive patients undergoing hysterectomy for benign conditions answered a questionnaire on symptoms associated with urge and stress urinary incontinence. Of the 120 patients, 44 underwent vaginal and 76 abdominal hysterectomy. Follow-up questionnaires were administered at 1 and 3 years postoperatively. RESULTS: Postoperatively, the questionnaire was answered by 115 (96%) of 120 patients after 1 year and by 107 (89%) after 3 years of follow-up. At surgery, the mean patient age was 49.5 years (range 32 to 78). In the abdominal hysterectomy cohort, a tendency was found for decreased episodes of urinary incontinence, although the difference was not significant. No significant changes were noted in micturition frequency. In the vaginal hysterectomy cohort, no significant changes were detectable in the symptoms associated with urge or stress incontinence, and no significant changes were noted in micturition frequency. For the entire hysterectomy group, a significant decrease occurred in stress urinary incontinence symptoms (P = 0.03). Subgroup analysis did not identify any particular risk factors for the development of urinary incontinence after hysterectomy. CONCLUSIONS: In contrast to the results of several studies, the results of our 3-year prospective study showed that total hysterectomy, independent of route, was not associated with an increase in urge or stress urinary incontinence symptoms.

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.
