Abstract:
Objective:To observe the morphological characteristics of urogenital hiatus in patients with gestational diabetes mellitus (GDM) after vaginal delivery.Methods:This study included 192 pregnant patients from Henan Provincial People′s Hospital who met the conditions between Jan.2020 and Aug.2021. All participants were screened for GDM by oral glucose tolerance test (OGTT) or fasting blood glucose at 24-28 weeks of pregnancy, and were divided into GDM group (34 cases) and non-GDM group (158 cases) based on the presence or absence of GDM. All participants underwent pelvic floor ultrasonography at the first trimester (6-8 gestational weeks), 3 days postpartum, 6 weeks postpartum, 6 months postpartum, and 1 year postpartum. Area of urogenital hiatus (AUH), transversal diameter of urogenital hiatus (TDUH) and anteroposterior diameter of urogenital hiatus (APDUH) were measured using Smart Pelvic. The Logistic regression model was used to calculate and match the propensity score between the GDM group and the non-GDM group.Results:In the non-GDM group, TDUH during rest maneuver at 6 weeks postpartum( P=0.319), the indicators during rest and contract maneuver at 6 months postpartum( P=0.586, 0.877, 0.164, 0.226, 0.465, 0.097), and TDUH during tension maneuver at 1 year postpartum( P=0.643) returned to the level of early pregnancy. In the GDM group, the indicators during rest maneuver and TDUH during contract maneuver at 6 months postpartum recovered to the level of early pregnancy ( P=0.647, 0.584, 0.376, 0.440), while APDUH and AUH during contract maneuver ( F=7.784, 9.785; P=0.005, <0.001) and the indicators during tension maneuver at 1 year postpartum( F=15.343, 11.974, 17.981; P<0.001) did not recover to the level of early pregnancy. After propensity score matching, APDUH and AUH during tension maneuver at 1 year postpartum in the GDM group were significantly greater than those in the non-GDM group( t=2.810, 2.926; P=0.006, 0.004). Conclusions:The pelvic floor muscles of GDM patients after vaginal delivery are more severely damaged, and the recovery speed is slower. Pelvic floor muscle exercise during pregnancy and enhanced postpartum follow-up are needed to prevent, diagnose and treat pelvic floor dysfunction early.
