目的分析经会阴超声在女性盆底功能障碍性疾病诊断中的应用价值。方法选取2014年6月至2016年6月深圳市南山区人民医院收治的48例女性盆底功能障碍性疾病患者(观察组)及30例盆底正常女性(对照组)为研究对象。比较两组经会阴超声检查各指标(膀胱颈下降距离、尿道旋转角度等)。将经会阴二维、三维超声检查结果与女性盆底功能障碍性疾病诊断“金标准”结果进行对照分析,比较经会阴二维、三维超声检测方法对其诊断的敏感性、特异性、阳性预测值、阴性预测值及诊断符合率。结果观察组患者尿道倾斜角、膀胱颈到耻骨联合下缘距离、宫颈到耻骨联合下缘距离、直肠壶腹部最低点至耻骨联合下缘距离、肛提肌尿道间隙均<对照组,膀胱颈下降距离等其他指标>对照组,差异均有统计学意义(P<0.05)。经会阴三维超声检查对女性盆底功能障碍性疾病的诊断准确率92.3%,显著高于二维超声检查的78.2%(P<0.05)。经会阴二维超声检查对女性盆底功能障碍性疾病诊断的敏感性、特异性、阳性预测值、阴性预测值分别为72.9%、53.3%、71.4%、41.0%;三维检查分别为91.7%、93.3%、95.7%、87.5%,三维检查优于二维检查(P<0.05)。结论在女性盆底功能障碍性疾病的临床诊断中,经会阴超声检查能够清晰地显示盆底结构,提高诊断准确性,具有重要的应用价值。 Objective To analyze the value of transperineal ultrasonography in the diagnosis of pelvic floor dysfunction in women. Methods 48 patients with pelvic floor dysfunction (observation group) and 30 normal pelvic floor women (control group) were enrolled in the Nanshan District People’s Hospital of Shenzhen City from June 2014 to June 2016. The two groups were compared by perineal ultrasound examination indicators (bladder neck down distance, urethral rotation angle, etc.). The results of two-dimensional and three-dimensional perineal ultrasound and female pelvic floor dysfunction disease diagnosis “gold standard ” results were compared and analyzed by the perineal two-dimensional, three-dimensional ultrasound detection of its diagnostic sensitivity, specificity, Positive predictive value, negative predictive value and diagnostic coincidence rate. Results In the observation group, the urethra tilt angle, the distance from the bladder neck to the pubic symphysis, the distance from the cervix to the pubic symphysis, the distance from the lowest point of the rectum ampulla to the lower edge of the pubic symphysis, and the levator ani urethra were all < Distance and other indicators> control group, the difference was statistically significant (P <0.05). The diagnostic accuracy of three-dimensional perineal ultrasound in women with pelvic floor dysfunction was 92.3%, which was significantly higher than that in two-dimensional ultrasonography (78.2%, P <0.05). The sensitivity, specificity, positive predictive value and negative predictive value of transperineal two-dimensional sonography in the diagnosis of pelvic floor dysfunction were 72.9%, 53.3%, 71.4% and 41.0% respectively. The three-dimensional examinations were 91.7% 93.3%, 95.7% and 87.5% respectively. The three-dimensional examination was superior to the two-dimensional examination (P <0.05). Conclusion In the clinical diagnosis of pelvic floor dysfunction in women, transperineal ultrasonography can clearly show the structure of the pelvic floor and improve the diagnostic accuracy, which has important application value.
