腔内超声节段分析法诊断先天性子宫及阴道畸形

目的探讨应用腔内(经阴道或经直肠)三维超声节段分析法诊断先天性子宫及阴道畸形的价值。方法将226例先天性子宫及阴道畸形患者分为A、B两组。A组154例,采用回顾性分析,对比分析其经腹或腔内二维超声检查的结果及临床结局;B组72例,采用前瞻性研究,对比分析应用节段分析法经腔内三维超声检查的结果及临床结局。结果 A组154例中,二维超声检查诊断符合率为64.29%(99/154),漏、误诊55例,未进行详细分类;B组72例中,腔内三维超声节段分析法的诊断符合率达95.83%(69/72),漏、误诊3例。结论应用腔内三维超声节段分析法可明显提高对于先天性子宫及阴道畸形的定性及分类诊断的准确性。

Endoluminal ultrasound and segmental analysis in diagnosis of congenital malformation of the uterus and vagina

Objective To investigate the diagnostic value of endoluminal ultrasound (transvaginal and transrectal ultrasound) and segmental analysis with three-dimensional ultrasonography for congenital malformation of the uterus and vagina. Methods A total of 226 patients with clinically confirmed congenital malformations of the uterus and vagina were enrolled and divided into two groups. Group A included 154 cases, the findings of transabdominal or endoluminal two dimensional ultrasonography were retrospectively compared with clinical diagnosis. Group B included 72 cases, the results of segmental analysis by endoluminal three-dimensional ultrasonography were perspective studied and then compared with clinical diagnosis. Results In group A, 99 of 154 cases with congenital malformations of the uterus and vagina were diagnosed by two dimensional ultrasound, while 55 cases were missed or misdiagnosed. The coincidence rate was 64.29% (99/154). In group B, since the introduction of three dimensional ultrasonography and segmental analysis, 69 of 72 cases were defined, with the coincidence rate of 95.83% (69/72), while 3 cases were missed diagnosed or misdiagnosed. Conclusion Transluminal three-dimensional ultrasonography and segmental analysis have essential diagnostic value, which can improve the accuracy of diagnosis and classification of congenital malformation of the uterus and vagina.
