目的：探讨腔内三维超声与宫腔镜检查对残角子宫畸形的诊断价值。方法：收集2009 年3 月～2013 年3 月我院收治的疑似残角子宫畸形的患者，分别行腔内三维超声和宫腔镜检查，以病理诊断结果为“金标准”，比较两组检查结果的差异。结果：三维超声的灵敏度与宫腔镜比较，差异有统计学意义（P<0.05），两组的特异度、准确性、阳性预测值、阴性预测值差异无统计学意义（P>0.05）；三维超声检查阳性检出率80.65%，阴性检出率19.35%，宫腔镜检查阳性检出率59.68%，阴性检出率40.32%，两组检出率差异无统计学意义（X2=0.498，P>0.05）。结论：腔内三维超声诊断残角子宫畸形具有无创、操作简便的特点，但是漏诊率高于宫腔镜结果。

英文摘要:

Objective:To investigate the value of endoluminal three dimensional ultrasonography and hysteroscopy in diagnosis for the rudimentary horn of uterus malformation.Methods:Patients who were suspected of rudimentary uterine horn in our hospital from March 2009 to March 2013 were collected, and received examination of endoluminal three dimensional ultrasound and hysteroscopy, the differences of results of two groups were compared , the pathological diagnosis were utilized as "gold standard".Results:There was statistically significant difference in the sensitivity between endoluminal three dimensional ultrasound and hysteroscopy (P<0.05), but the specificity, accuracy, positive predictive value, and negative predictive value of two groups presented no statistical difference(P>0.05). Positive detection rate of three dimensional ultrasound examination was 80.65%, and the negative rate was 19.35%. The positive detection rate of hysteroscopy was 59.68%, and the negative rate was 40.32%. There was no significant difference in positive detection rate (x2=0.498, P>0.05).Conclusion:Intracavity three-dimensional ultrasound had the features of non-invasive,simple operation in the diagnosis of rudimentary uterine horn deformity, but the rate of missed diagnosis was higher than that of hysteroscopy results.
