肾结核影像学检查方法评价

Evaluation of imaging diagnostic methods of the renal tuberculosis

目的分析肾结核的影像学表现，评价各种检查方法的优缺点，选择敏感的检查手段。方法收集经手术病理证实的肾结核患者48例，分析其腹部平片（KUB）、静脉尿路造影（IVP）、肾逆行造影（AP）及CT表现，并进行比较。结果对于肾结核的诊断率，KUB＋IVP为41．7％（20／48），AP62．5％（10／16），CT 100％（48／48）。CT断面上聚集成“花瓣”状的多发低密度灶。结论CT扫描对肾结核的诊断具有重要价值。

Objective To analyze the image findings of renal tuberculosis and evaluate the merits and disad vantages of various imaging diagnostic methods, then choose the most sensitive one. Methods The KUB, IVP, AP and CT findings of 48 patients with renal tuberculosis which had been convinced by operations were evaluated and compared. Results The diagnosis rates of KUB and IVP were 41.7 % （20/48）, AP of 62.5 % （10/16）, CT of 100 % （48/48）. The characteristic findings of CT were multiple low density lesions, with ＂flower petals＂ shape gathered in sections. Conclusion CT has a great value for diagnosing renal tuberculosis.
