摘　　要：目的探究盆底超声参数及盆底肌电生理参数与女性产后尿失禁患者病情严重程度的相关性。方法回顾性将2018年1月至2023年3月在兰州市第一人民医院就诊的215例产后42 d的产妇纳入本次研究,其中压力性尿失禁(SUI)产妇65例,纳入研究组,150例无SUI产妇纳入对照组。研究组产妇根据病情严重程度又分为轻度组(n=25)、中度组(n=22)和重度组(n=18),产妇均接受盆底超声及盆底肌电生理检查,比较各组的盆底超声参数[膀胱尿道后角(PUA)、尿道倾斜角(UTA)、膀胱位置(BDP)、膀胱颈的位置(BNP)、膀胱颈移动度(BND)、尿道旋转角(URA)、肛提肌裂孔面积]及肌电生理参数(前基线平台期平均值、前基线平台期高张情况、Ⅱ类肌纤维收缩期电位平均值、Ⅱ类肌纤维收缩期时间、Ⅱ类肌纤维收缩期分级、后基线平台期平均值、后基线平台期高张情况、Ⅰ类肌纤维收缩期电位平均值、Ⅰ类肌纤维收缩期时间、Ⅰ类肌纤维收缩期分级)。结果研究组静息状态下的PUA、UTA、肌裂孔面积分别为(121.91±15.25)°、(22.89±7.61)°、(16.67±4.05)cm^(2),均显著高于对照组[(77.46±7.57)°、(18.63±6.39)°和(14.35±3.31)cm^(2)],差异均有统计学意义(P<0.05);2组静息状态下的BDP和BNP比较,差异均无统计学意义(P>0.05);研究组最大Valsalva动作状态下的PUA、UTA、URA、肌裂孔面积分别为(168.38±15.99)°、(36.19±10.27)°、(50.06±14.39)°和(18.84±4.10)cm^(2),均显著高于对照组[(85.10±10.37)°、(16.94±5.08)°、(33.50±9.48)°和(14.59±3.75)cm^(2)],最大Valsalva动作状态下的BDP、BNP和BND分别为(2.21±1.03)、(2.40±1.05)和(25.97±6.52)mm,均显著低于对照组[(11.40±5.02)、(11.22±4.41)和(14.50±3.49)mm],差异均有统计学意义(P<0.05)。2组的前基线平台期电位均值、前基线平台期分级、后基线平台期电位均值、后基线平台期分级、Ⅰ类肌纤维收缩期电位均值、Ⅰ类肌纤维收缩期时�Objective To investigate the correlation between pelvic floor ultrasound parameters,pelvic floor electromyographic parameters,and the severity of postpartum stress urinary incontinence(SUI) in women.Methods A total of 215 postpartum women who visited The First People's Hospital of Lanzhou from January 2018 to March 2023 were included in this study.Of these,65 women with SUI were assigned to the study group,while 150 women without SUI were assigned to the control group.The study group was further divided into the mild group(n=25),the moderate group(n=22),and the severe group(n=18) based on the severity of their condition.All participants underwent pelvic floor ultrasound and electromyographic examinations,and the pelvic floor ultrasound parameters[posterior urethral angle(PUA),urethral tilt angle(UTA),bladder dome position(BDP),bladder neck position(BNP),bladder neck displacement(BND),urethral rotation angle(URA),and levator ani muscle hiatus area] and electromyographic parameters(terms of baseline plateau potential mean,baseline plateau grading,type Ⅱmuscle fiber contraction potential mean,type Ⅱ muscle fiber contraction time,and type Ⅱmuscle fiber contraction grading,post-baseline plateau potential mean,post-baseline plateau grading,type I muscle fiber contraction potential mean,type I muscle fiber contraction time,and type I muscle fiber contraction grading) among the groups were compared.Results In the study group,the resting angles of PUA,UTA,and levator hiatus area were(121.91±15.25)°,(22.89±7.61)°,and(16.67±4.05) cm^(2),which were significantly higher than those in the control group [(77.46±7.57)°,(18.63±6.39)°,and(14.35±3.31) cm^(2)],the differences were statistically significant(P<0.05).There were no statistically significant differences in the resting positions of the BDP and BNP between the two groups(P>0.05).The maximum Valsalva angles of PUA,UTA,URA,and hiatus area in the study group were(168.38±15.99)°,(36.19±10.27)°,(50.06±14.39)°,and(18.84±4.10) cm^(2),respectively,which were
