肾盂移行细胞癌的影像诊断

Diagnostic sensitivity of varied imaging techniques for pyelic transitional cell carcinoma

目的比较静脉尿路造影(IVU)、逆行尿路造影(RU)、B超、CT检查对肾盂移行细胞癌的诊断敏感性。方法回顾性分析28例经手术病理证实的肾盂移行细胞癌的影像学资料,18例经IVU检查;14例经逆行肾盂造影;28例均经CT检查,其中11例为平扫,17例为平扫加增强;20例经超声检查。结果对照手术病理结果,IVU的敏感性为55.6%(10/18);逆行肾盂造影的敏感性为92.9%(13/14);CT检查的敏感性为89.3%(25/28);B超的敏感性为60%(12/20)。结论RU准确率最高,CT和B超其次,IVU最低,但因IVU是无创性检查,临床依然将其作为肾盂移行细胞癌常规的首选检查方法,RU,CT和B超作为IVU重要的补充。

Objective To compare the diagnostic sensitivity of varied imaging techniques including intravenous urethrography （IVU）,retrograde urethrography （RU）,uhrasonography （US）,and computed tomography （CT）for pyelic transitional cell carcinoma.Methods Twenty-eight patients with surgically and pathologically proved pyelic transitional cell carcinoma （PTCC） initially underwent CT scans （of whom,11 plain scan,17 contrast enhancement）.18 patients underwent additional IVU,14 patients underwent additional RU,and 20 patients underwent additional US examinations.Results Compared with surgic and pathologic findings,the diagnostic sensitivity of CT,IVU,RU and US for PTCC was 89.3%,55.6%,92.9%,and 60%,respectively.Conclusion Although the diagnostic sensitivity of IVU for PTCC is lower than that of other 3 imaging techniques but it is a noninvasive examination and therefore it is still first choice to diagnose PTCC,while RU,CT and US may be taken as complementary means.
