目的:探讨经阴道 360°腔内三维超声在阴道周围囊性病变中的应用价值.方法:常规经阴道超声检查发现阴道周围囊性病变 42 例,先利用二维超声观察阴道周围囊性病变大小、位置及与阴道、尿道和直肠的关系,再利用经阴道 360°腔内三维超声获取矢状切面、横切面、冠状切面、任意切面图像,不同视角观察阴道周围囊性病变的空间关系,从而进行定位诊断.结果:常规经阴道超声检查发现阴道周围囊性病变 42 例,经手术病理、尿道镜、肾盂输尿管造影证实阴道壁囊肿 21 例、尿道旁腺囊肿 13 例、尿道憩室 3 例、先天性输尿管异位开口 2 例、骶尾部囊性畸胎瘤 3 例.经阴道 360°腔内三维超声检查诊断符合率为95.23%(40/42),经阴道常规二维超声检查诊断符合率为 71.42%(30/42),经阴道 360°腔内三维超声检查与经阴道常规二维超声检查诊断符合率比较,差异具有统计学意义(P<0.05).结论:经阴道 360°腔内三维超声是准确、方便、快捷诊断阴道周围囊性病变的影像学手段,具有重要的应用价值.
Abstract
Objective:To investigate the value of 360° transvaginal three-dimensional ultrasound in the diagnosis of cystic lesions around the vagina.Methods:Forty-two cases of cystic lesions around the vagina were detected by routine transvaginal ultrasonography.Initially,two-dimensional ultrasound was used to observe the size,location,and relationships with the vagina,urethra and rectum of cystic lesions around the vagina.The images of sagittal,transverse,coronal and arbitrary sections were obtained by 360° transvaginal three-dimensional ultrasound and the spatial relationships of cystic lesions around the vagina were observed from different perspectives for positioning diagnosis.Results:Forty-two cases of perivaginal cystic lesions were found by routine transvaginal ultrasound and confirmed by surgical pathology,urethroscopy and renal pelvis ureterography,there were 21 cases of vaginal wall cysts,13 cases of paraurethral gland cysts,3 cases of urethral diverticulum,2 cases of congenital ectopic opening of ureter and 3 cases of sacrococcygeal teratomas.The diagnostic accuracy of transvaginal 360° three-dimensional ultrasound was 95.23%(40/42),and that of two-dimensional ultrasound was 71.42%(30/42).The difference between transvaginal 360° three-dimensional ultrasound and conventional transvaginal two-dimensional ultrasound diagnosis was statistically significant(P<0.05).Conclusions:Transvaginal 360° three-dimensional ultrasound for the diagnosis of perivaginal cystic lesions is an accurate,convenient,and rapid imaging method with significant practical value.
