目的 分析经会阴超声与磁共振 成像(MRI)对女性盆底功能障碍性疾病 (PFD)的诊断价值。方法 回顾性分析我 院同时行经会阴超声及MRI检查的84例盆 腔器官脱垂(POP)患者(观察组)和同期体 检的84名健康女性(对照组)临床资料， 比较两组经会阴超声及MRI检查结果差 异，并分析观察组2种检查方法与金标准 (手术)的检出情况差异及其相应的诊断价 值。结果 MRI检查显示，观察组屏气用 力(Valsalva动作)时膀胱颈、子宫颈及 肛管直肠连接下降距离均较对照组高(P ＜0.05)；经会阴超声则显示观察组膀胱 颈、宫颈及直肠壶腹部最低点至耻骨联合 下缘距离均较对照组低(P＜0.05)。84例 PFD患者共检出128个部位脱垂，其中MRI 检出与金标准一致的有112个；经会阴超 声检出与金标准一致的有94个。MRI与经 会阴超声诊断的特异度、阳性预测值比 较，差异无统计学意义(P＞0.05)；MRI诊 断灵敏度、阴性预测值、准确率均高于经 会阴超声(P＜0.05)。结论 经会阴超声与 MRI均可用于POP诊断，但MRI诊断灵敏度 及准确性更高。

Objective To analyze the diagnostic value of transperineal sonography and magnetic resonance imaging (MRI) in female pelvic floor dysfunction (PFD). Methods The clinical data, transperineal sonography and MRI data of 84 patients with pelvic organ prolapse (POP) (observation group) and 84 healthy women (control group) at the same time were analyzed retrospectively. The results were compared, and the detection conditions and diagnostic value of the two examination methods were analyzed. Results MRI examination showed that the decreasing distances of bladder neck, cervix and anorectum when breath holding (Valsalva movement) were all significantly higher in the observation group than those in the control group (P<0.05). Transperineal sonography showed that the distances from the lowest point of bladder neck, cervix and rectal ampulla to the inferior margin of pubic symphysis in the observation group were lower than those in the control group (P<0.05). A total of 128 lesions of prolapses were detected in 84 PFD patients, of which 112 cases were detected by MRI and 94 cases were detected by transperineal sonography. There was no significant difference in specificity and positive predictive value between MRI and transperineal sonography diagnosis (P>0.05). The diagnostic sensitivity, negative predictive value and accuracy of MRI were higher than those of transperineal sonography (P<0.05). Conclusion Transperineal sonography and MRI are favorable for the diagnosis of POP, and the accuracy of MRI is higher than transperineal sonography.
