对应用B超诊断的118例肾肿瘤进行术前定性诊断分析.所有病例均经手术及病理证实.结果表明,B超对肾肿瘤的检出率较高,为92.2%,而定性诊断率并不高,仅为49.1%,误诊率18.1%,假阳性率1.7%,术前肿瘤性质未能确定的占32.8%.认为B超作为一种影像学检查技术,只能对部分具有典型声像图特征的肿瘤作出正确的术前定性诊断,而对图像较复杂,具交叉现象的肾肿瘤难以鉴别其性质,如结合其它影像学检查,可提高肾肿瘤的术前定性诊断率.%Preoperative qualitative diagnoses of 118 eases of renal tumour.made by B-mode ultrasound were analyzed.The final diagnoses were proven operatively and pathologically.The resultsshowed that by B-mode altrasound the detective rate was 92.2%,a correct qualitative diagnosis rate 49.1%,incorrect rate 18.1%and false positive rate 1.7%.Qualitatively unidentified turnouts accounted for 32.8%of all the cases.It is assumed that B-mode ultrasound can be used to make correct qualitative diagnosis only on certain tumours with typical image features.It is difficult for it to distinguish some tumours which have complicated displays.The accuracy of preoperative qualitative diagnosis could be raised by combining B-mode uhradound with other imaging technologicol examinations.
