膀胱气钡双重造影与病理标本及CT扫描对照分析

Evaluation of pneumobarium double contrast cystography:Correlation study of pathologic specimen and CT scanning

目的 :评价膀胱气钡双重造影在膀胱疾病中的诊断价值。方法 :应用浓度为 15 0 % - 2 0 0 %W/V的硫酸钡混悬液 5ml- 10ml,过滤空气 2 0 0ml- 2 5 0ml做膀胱气钡双重造影 ( 5 1例 ) ,观察膀胱解剖结构及病灶细微结构的显示情况 ,并与术后标本及CT扫描 ( 2 6例 )对照分析。结果 :①造影对膀胱粘膜皱襞 ,膀胱壁及病灶的显示满意率分别为 82 % ,10 0 % ,98%。而CT扫描分别为 0 ,10 0 % ,94 %。②造影对某些病变如膀胱憩室 ,膀胱结核 ,神经原性膀胱等敏感性明显优于CT扫描。③造影对膀胱癌外侵的显示不如CT扫描。结论 :造影对膀胱解剖结构及病灶的显示有独到之处 ,是一种很有价值的影像检查方法。

Objective:To evaluate the diagnostic value of pneumobarium double contrast cystography.Materials and methods:51 cases were examined in pneumobarium double contrast with 5ml-10ml barium(150-200% w/v) and 200ml-250ml air.The manifestations of urocystic anatomy morphology and lesions were analysed with cystography and compared with postoperative samples and CT images(26 cases).Results:1.The plica mucosa,urocystic wall and lesion displayed in pneumobarium double contrast and CT image were 82%,100%,98% and 0,100%,94% respectively.2.Double contrast cystography showed some lesions such as vesical diverticulum,cystophthisis,neurogenic bladder etc were better than CT scan.3.Pneumobarium double contrast cystography was not as good as CT scan for the extracystic infiltration.Conclusion:Pneumobarium double contrast cystography can manifest urocystic anatomy structure and lesions very clearly,and is a valuable method.
