Evaluation of pelvic floor function of postpartum pelvic floor ultrasound in pregnant women with multiple pregnancies

Abstract

Objective: To probe the effect of multiple pregnancy on pelvic floor function of pregnant women, Pelvic floor ultrasonography was performed on the 42 day postpartum women.And the bladder neck mobility, bladder and urethral posterior angle and pelvic diaphragmatic hiatus area were measured. Methods: Collect 200 cases 42 day postpartum women who visited the second hospital of Jilin University from July 2015 to June 2017, of which 100 cases of primipara belong to group A, 100 cases of multiple pregnancy belong to group B, and 100 cases without maternal at the same age belong to the control group, ultrasound measurement of the bladder neck mobility, bladder and urethral posterior angle and pelvic diaphragmatic hiatus area were measured.t test were proformed respectively between the three groups, P<0.05 was considered statistically significant difference. Results: In the control group, the bladder neck mobility is (2.59±0.51) cm , the bladder neck mobility in A group is (2.99±0.69) cm, the bladder neck mobility in B group is (3.36±0.71) cm; the bladder and urethral posterior angle in the control group is (112.56±13.61)°, the bladder and urethral posterior angle in the control group after Valsalva action angle is(135.37±12.17)°, the bladder and urethral posterior angle in A group is(119.26±15.80)°, the bladder and urethral posterior angle in group A after Valsalva action is(141.79±12.08)°, the bladder and urethral posterior angle in B group is(123.62±16.20)°, the bladder and urethral posterior angle in group B after Valsalva action is (148.92±13.60)°; the pelvic diaphragmatic hiatus area in the control group is (13.35±2.86) cm(2,) the pelvic diaphragmatic hiatus area in the control group after Valsalva action is(15.28±3.15) cm(2,) the pelvic diaphragmatic hiatus area in A group is(17.52±3.19) cm(2,) the pelvic diaphragmatic hiatus area in A group ater Valsalva action is (18.06±5.13_the pelvic diaphragmatic hiatus area) cm(2,) the pelvic diaphragmatic hiatus area in B group is (18.26±4.18) cm(2,) the pelvic diaphragmatic hiatus area in B group after Valsalva action is (20.3±3.53) cm(2).In group A, group B and the control group, the measured value of the bladder neck mobility, bladder and urethral posterior angle and pelvic diaphragmatic hiatus area were examined by t test, and P<0.05, which means the difference was statistically significant. Conclusion: Pregnancy can affect the function of female pelvic floor, and the effect of parturient is more significant than that of the primipara.
