目的:本研究通过磁共振成像(MRI)检查对PFD患者进行严重程度分级,探讨其与临床广泛应用的盆腔器官脱垂分级量表(POP-Q)所得结果的相关性。方法:2011年4月至2012年5月,门诊收集PFD患者15例,行MRI静息相、收缩相和排泄相检查,以耻骨尾骨线(PCL)作为参考,将所得分级结果与临床POP-Q分级结果相关联。结果:配对计数资料的卡方检验结果为前部和中音部.MRI分级与临床POP-Q分级的一致性较好(前部κ=0.438,standard error=0.16;中部κ=0.423,standard error=0.16),而后部MRI分级与临床POP-Q分级的一致性较差(x=0.057,standard error=0.17)。结论:本试验研究表明盆底器官前部和中部MRI分级与临床POP-Q分级的一致性较好,MRI分级今后可能成为临床体检的替代方法。而后部MRI分级与临床POP-Q分级的一致性较差,由于临床分级法对于盆底结构后部脱垂的诊断准确性低,客观性较强的MRI分级方法可能在这部分疾病的诊断中具有前景。
OBJECTIVE: In this study, the severity of patients with PFD was graded by magnetic resonance imaging (MRI) and the correlation with the results of POP-Q in clinical practice. Methods: From April 2011 to May 2012, 15 outpatients with PFD were enrolled. The resting phase, contractive phase and excretory phase of MRI were examined. PCL was used as a reference. The results were compared with clinical POP- Q grade results associated. Results: The chi-squared test results of paired count data showed that the consistency between MRI classification and clinical POP-Q classification was good (front κ = 0.438, standard error = 0.16; middle κ = 0.423, standard error = 0.16), while the posterior MRI grading was less consistent with the clinical POP-Q classification (x = 0.057, standard error = 0.17). CONCLUSIONS: This study shows that MRI consistency between the anterior and middle pelvic floor organ and clinical POP-Q classification is consistent. MRI classification may become an alternative to clinical examination in the future. The posterior MRI grading and clinical POP-Q classification of the consistency is poor, because of the clinical classification of pelvic floor posterior prolapse diagnosis of low accuracy, strong objective MRI grading method may be in the diagnosis of this part of the disease Promising.
