Effect of mode of delivery and parities on the occurrence of urinary incontinence during pregnancy

Resumo

Introduction: The urinary incontinence (UI) is a common pathology among women. In the gestation period, it is even more predominant, affecting between 20% and 67%. Objective: To evaluate the relation between modes of delivery and parity on the occurrence of urinary incontinence during pregnancy. Methodology: 80 pregnant and postpartum women, treated at the Hospital da Mulher, in Campo Grande, MS, Brazil, were selected during September and October 2011, following the inclusion and exclusion criteria of the research. The evaluation protocol consisted of a questionnaire on the clinical history of the patients, gynecological complications, urogynecologic and obstetric information. Results: For independent samples, the comparison between the main values observed for the UI was given by the Mann-Whitney test and correlations betweenurinary incontinence and other variables were given by the Spearman´s rank correlation coefficient. The studied group consisted of 40 (50%) primiparous and 40 (50%) multiparous women. The correlation between the following variables was not significant: parity and UI (r = 0.04, p = 0.7); parity and SUI (r = -0.81, p = 0.5); and parity and urge incontinence (r = 0.14, p = 0.19). In addition, the correlation obtained between vaginal delivery and the presence of urinary incontinence in primiparous (r = 0.08, p = 0.61) and in multiparous (r = -0.05, p = 0.76) was also not significant. The same occurs when cesarean delivery is correlated to urinary incontinence in primiparous (r = -0.08, p = 0.61) and multiparous women (r = -0.10, p = 0.5).Conclusion: Parity and mode of delivery were not significantly associated with the occurrence of urinaryincontinence during pregnancy.
