Ultrasonographic evaluation of urethrovesical junction mobility: correlation with type of delivery and stress XXXX .

@entity1 @entity365 @entity322 @entity8018
INTRODUCTION AND HYPOTHESIS: A relationship between @entity322 and @entity8018 of the urethrovesical junction (UVJ) during pregnancy has been described. The aim of the study was to compare the effects of @entity365 ( @entity365 ) and caesarean section (CS) on UVJ mobility. METHODS: The retrovesical angle (RVA) and the anterior angle between the UVJ and the pubic bone, the pubovesical angle (PVA), were evaluated ultrasonographically in controls and pregnant @entity1 during their first pregnancy between 38 and 40 weeks, and then re-evaluated 6 weeks and 6 months after delivery. All @entity1 completed a validated questionnaire (ICIQ-SF). Differences between and within groups were assessed with Student's t test, the chi-squared test for trend, and one-way two-tailed analysis of variance with Scheff  's post-hoc test. The correlation between PVA and RVA was evaluated using the Spearman R correlation. The positive predictive value, negative predictive value, sensitivity and specificity for the prediction of stress @entity322 (SUI) symptoms were also determined. RESULTS: Included in the study were 42 controls and 217 pregnant @entity1 . PVA at rest, during cough and Valsalva manoeuvre was significantly higher in pregnant @entity1 than in controls and in @entity1 6 weeks after @entity365 in comparison with @entity1 who had undergone CS. @entity1 affected by SUI showed a significantly higher PVA. RVA did not differ between subjects affected or not by SUI symptoms. PVA and RVA were not correlated with each other. CONCLUSIONS: PVA and RVA are increased in pregnant @entity1 in comparison with controls. In @entity1 undergoing @entity365 , PVA is restored significantly later than in those undergoing CS. The change in RVA after pregnancy and delivery seems to persist longer than the change in PVA.
