ABSTRACT We estimated the incidence and remission of lower urinary tract symptoms during the 12 years following the first pregnancy and delivery.
In a cohort study 242 primiparae were questioned about lower urinary tract symptoms 3 months, 5 years and 12 years after the first delivery.
From 3 months to 5 years after first delivery the incidence of stress urinary incontinence, urge urinary incontinence, urgency, diurnal frequency and nocturia was 56 of 213 cases (26.3%), 33 of 219 (15.1%), 33 of 206 (16.0%), 49 of 219 (22.4%) and 6 of 225 (2.7%), respectively. Remission of stress urinary incontinence, urge urinary incontinence, urgency, diurnal frequency and nocturia during the same period occurred in 1 of 11 cases (9.1%), 2 of 5 (40%), 2 of 5 (40%), 4 of 7 (57.1%) and 1 of 1 (100%), respectively. From 5 to 12 years after the first delivery the incidence of stress urinary incontinence, urge urinary incontinence, urgency, diurnal frequency and nocturia was 40 of 158 cases (25.3%), 25 of 188 (13.3%), 24 of 175 (13.7%), 40 of 174 (23.0%) and 13 of 220 (5.9%), respectively. Remission of stress urinary incontinence, urge urinary incontinence, urgency, diurnal frequency and nocturia during the same period occurred in 14 of 66 cases (21.2%), 13 of 36 (36.1%), 22 of 36 (61.1%), 14 of 52 (26.9%) and 4 of 6 (66.7%), respectively. Of 62 women with pure stress urinary incontinence during the first pregnancy and puerperium 20 (32.2%) had pure stress urinary incontinence, 3 (4.8%) had pure urge urinary incontinence and 15 (24.2%) had mixed urinary incontinence 12 years later. Of 13 women with pure urge urinary incontinence during the first pregnancy and puerperium 3 (23.1%) had pure urge urinary incontinence, 2 (15.4%) had pure stress urinary incontinence and 3 (23.1%) had mixed urinary incontinence 12 years later. The overall prevalence of lower urinary tract symptoms 12 years after the first delivery increased significantly.
The incidence and remission of lower urinary tract symptoms after the first pregnancy and delivery fluctuate and the types of urinary incontinence may interchange, while the overall prevalence of lower urinary tract symptoms increases in the long term.

    ABSTRACT: The goal of the current study was to systematically review the literature concerning urinary incontinence and pregnancy, in order to develop recommendations for clinical practice. The prevalence of urinary stress incontinence and overactive bladder symptoms increase with gestational age during pregnancy (from the first to the third trimester), and decrease during the third months following delivery. Obstetrics factors (position during delivery, length of the second part of the labour, forceps, episiotomy, epidural or pudendal anaesthesia) do not modify the risk of post-partum or long term urinary incontinence. At short term follow-up, caesarean delivery is associated with a lower rate of post-partum urinary incontinence. At long term follow-up, data are lacking. Non elective caesarean section is not associated with a decrease in the rate of post-partum or long-term urinary incontinence. Elective caesarean section and systematic episiotomy are not recommended methods for the prevention of post-partum urinary incontinence (grade B), even in “high risk” women. Pelvic floor muscle therapy is the first line treatment for prenatal or post-partum urinary incontinence (grade A).

    ABSTRACT: This study aims to investigate the effects of simulated birth trauma and ovariectomy on detrusor muscarinic receptors (M2 and M3), urethral neuronal nitric oxide synthase (nNOS), and estrogen receptor beta (ER beta). Forty primiparous rats were equally divided into five groups: group A--delivery, group B--delivery plus ovariectomy, group C--delivery plus balloon dilatation for 2 h, group D--delivery plus balloon dilatation for 4 h, and group E--delivery plus balloon dilatation for 2 h plus ovariectomy. The gene expression of M2, M3, nNOS, and ER beta were assessed by reverse transcription polymerase chain reaction. Significant decreases in mRNA expression of M2 receptors and nNOS (P < 0.05), and a significant increase in M3 mRNA expression (P < 0.05) were observed in groups D and E when compared with group A. Ovariectomy following birth trauma may synergistically impact the function of urinary tract, this being possibly related to the modification of the gene expression of muscarinic receptors.

    ABSTRACT: To estimate the risk for stress urinary incontinence and pelvic organ prolapse surgery related to vaginal birth or cesarean delivery. A cohort study of all women having their first and all subsequent deliveries by cesarean (n = 33,167), and an age-matched sample of women only having vaginal deliveries (n = 63,229) between 1973 and 1983. Hazard ratios were calculated using Cox regression models with 95% confidence intervals. Women only having vaginal deliveries had increased overall risks of incontinence (hazard ratio, 2.9; 95% confidence interval, 2.4-3.6) and prolapse surgery (hazard ratio, 9.2; 95% confidence interval, 7.0-12.1) compared with women only having cesarean deliveries. Having only vaginal childbirths was associated with a significantly increased risk of stress urinary incontinence and pelvic organ prolapse surgery later in life compared with only having cesarean deliveries.
