摘要
目的 研究肾肿瘤的超声鉴别诊断规律,以减少漏、误诊。 方法 对术前超声诊断与术后病理结果相对照的81例肾肿瘤资料进行分析。 结果 恶性肿瘤占926%(75/81),良性肿瘤占74%(6/81)。术前超声诊断肾肿瘤72例,误、漏诊9例。准确性877%,敏感性888%,阳性预测值986%。假阳性1例。 结论 熟悉掌握结核性脓肾和多房性肾囊肿与囊性肾癌的超声表现及鉴别要点,是减少误诊的关键;详细询问病史。
PURPOSE To study the ultrasonic differential diagnosis of renal tumors,reducing the misdiagnosis rate.METHODS 81 cases of renal tumors which had been examined before operation by ultrasonography and verified by surgery and pathology were evaluated retrospectively.RESULTS Forty two renal cell carcinoma,sixteen transitional ell carcinoma,and twenty two other renal masses of various histologic types exhibited a broad spectrum of ultrasonographic findings.Nephromas were found to be 98.8% (80/81) to tally,in which malignant and benign tumors were 92.6%(75/81) and 7.4%(6/81).The diagnostic accuracy was 87.7%(71/81) in ultrasonography.The sensitivity of the ultrasonography was 88.8%.CONCLUSIONS To master the ulltrasonographic expressions and main points of differentiation in appraisal of the tuberculous pyonephrosis,multilocular cyst of kidney and cystic renal carcinoma is the key of reduction misdiagnosis,to inquire about the history of illness in detail and analysis imaging data overall is also an important factor to reduce misdiagnosis.
