Childbirth after mid-urethral sling surgery: effects on long-term success and complications.
To evaluate long-term outcomes in women with one or more childbirths after mid-urethral sling (MUS) surgery and potential differences in outcomes based on mode of delivery. A population-based cohort study using data from two national registries. Women registered with childbirth after MUS (case group) or without childbirth after MUS (control group), with equal follow-up time, underwent a structured telephone interview using a validated short-form urinary disease-specific questionnaire. Primary outcomes were current stress urinary incontinence (SUI) rate and change in cure rate. Secondary outcomes were effect of delivery mode, rates of repeat operations for SUI, complications, treatment satisfaction and urgency urinary incontinence rate. Childbirth as an independent risk factor for SUI recurrence was also evaluated. Seventy-two women with and 156 women without childbirth after MUS were included. Median follow-up time was 10 years for both groups. Subjective SUI cure rates were 82% (cases) and 75% (controls), respectively (p = 0.31). A significantly lower SUI cure rate was seen in the women with more than one childbirth after MUS (50% vs. 88% p = 0.006). No differences in primary or secondary outcomes were found between groups at follow-up, nor did mode of delivery affect outcomes. Childbirth after MUS was not an independent risk factor for subjective SUI recurrence (OR 0.8 CI 0.3-1.7). No differences in outcomes were seen between groups at follow-up independently of delivery mode. However, having more than one delivery after MUS seems to impact the continence status.
