The aim of this study was to evaluate the prevalence of stress urinary incontinence (SUI) in women in the third trimester of pregnancy. In total, 340 patients attending the Antenatal Clinic at the State University of Campinas (UNICAMP) were interviewed. Overall, 170 women (50%) presented SUI. Stress urinary incontinence did not correlate to either body mass index (BMI) or race. There was no correlation between parity and SUI, but when considering distinct types of effort, urine leakage on coughing (P = 0.0478) and laughing (P = 0.0046) were highly more frequent in multiparous women. One hundred eleven women had had only vaginal deliveries and 68 delivered by cesarean section. There was no difference between the two groups concerning incontinence, but multiparous women (> or = 4) who delivered exclusively vaginally demonstrated 2.0 times more chances to leak urine when compared to nulliparous women. This fact strongly suggests parity to be more relevant than delivery route as a risk factor to stress urinary incontinence. Nulliparous women presented with a high percentage (45.5%) of the symptom, emphasizing the elevated risk of SUI during first pregnancy.

ObjetivO: avaliar a freqüência de sintomas do trato urinário inferior (STUI) três anos após o parto em mulheres previamente entrevistadas no terceiro trimestre da gestação e comparar o impacto da gestação e do parto no desencadeamento dos STUI. Analisar o desconforto social e higiênico associado às queixas miccionais. MétOdOS: estudo prospectivo analítico. Em 2003, 340 gestantes foram selecionadas em um ambulatório de atendimento Pré-natal e responderam ao questionário pré-testado, com perguntas sobre STUI e dados obstétricos.Em 2006, três anos após o parto foi possível contatar por telefone 120 mulheres das 340 entrevistadas no primeiro estudo. As mesmas responderam ao segundo questionário, com perguntas sobre dados obstétricos, STUI e seu impacto social. Os STUI foram divididos em incontinência urinária de esforço (IUE) e sintomas urinários irritativos (SUI). Para análise foram utilizados os testes de McNemar e qui-quadrado (p<0,05). ReSultadOS: a ocorrência da IUE e de noctúria na gestação foi entre 57,5 e 80%; e o surgimento destes sintomas após o parto foi entre 13,7 e 16,7%, respectivamente. A urge-incontinência foi significativamente mais freqüente após o parto (30,5%) do que na gestação (20,8%). Apenas 35,6% das mulheres com SUI sentiam desconforto social, elevando-se este índice para 91,4% nas mulheres com SUI associado à IUE. COnCluSãO: a gestação, mais do que o parto, foi associada ao desencadeamento da IUE e de noctúria, enquanto o desencadeamento da urge-incontinência foi significativamente maior após o parto. A maioria das mulheres referiu que a presença da IUE causa problemas sociais. AbstractPuRPOSe: to evaluate the frequency of lower urinary tract symptoms (LUTS), three years after delivery in women previously interviewed at the third gestation trimester, and to compare the gestation and delivery impact on LUTS, analyzing the social and hygienic discomfort associated with micturition complaints. MetHOdS: analytical prospective study. In 2003, 340 pregnant women were selected in the pre-natal outpatient unit, and asked to answer a pre-tested questionnaire about LUTS and obstetric data. Three years after delivery, it was possible to get in touch by telephone with 120 of the 340 women who had been interviewed in the first study. They answered a second questionnaire about obstetric data, LUTS and its social impact. LUTS have been divided into stress urinary incontinence (SUI) and irritative urinary symptoms (IUS). McNemar's and chi-square tests were used for statistical analysis (p<0.05). ReSultS: SUI and nocturia have occurred in 57.5 and 80% of the pregnant women and the appearance of those symptoms after delivery, in 13.7 and 16.7%, respectively. Urge urinary incontinence has been significantly more frequent after delivery (30.5%) than in gestation (20.8%). Only 35.6% of the women with IUS presented social discomfort, but this rate has gone up to 91.4% in women with IUS associated with SUI. COnCluSiOnS: gestation, more than delivery, was associated with the appearance of SUI and nocturia, while t...

The aim was to estimate the incidence of stress urinary incontinence 3 years after delivery and its correlation to mode of delivery and parity. A longitudinal cohort study was conducted with 120 women at the Antenatal Clinic at the State University of Campinas. There was a significant difference in the incidence of postpartum stress urinary incontinence (SUI) among patients with SUI during pregnancy (p > 0.0001). Women that were asymptomatic during pregnancy and had vaginal delivery developed SUI 2.4 times more frequently than after c-section (19.2% and 8.0%, respectively). The incidence of SUI after delivery dropped significantly in the primiparous (p = 0.0073) and multiparous 2-3 (p < 0.0001), but not in the multiparous with four or more deliveries (66.7% to 60.0%) (p = 0.5637). A significant correlation has been observed between parity and SUI (p = 0.0299). Pregnancy possibly predisposes to SUI 3 years after delivery as well as parity. No significant correlation has been demonstrated between mode of delivery and SUI.

In the population under study pregnancy per se was associated to a high prevalence of irritative bladder symptoms.
