22例原发性输尿管癌的诊断分析

Diagnosis of Primary Ureteral Cancer:A Report of 22 Cases

目的提高输尿管癌的诊断水平。方法回顾性分析1993年3月至2010年5月收治的22例原发性输尿管癌患者的临床资料。结果临床表现血尿17例,腰痛10例,肾积水14例。阳性率较高的检查有逆行尿路造影、计算机断层扫描、磁共振成像和输尿管镜检查,阳性率分别为72.7%(8/11)、50%(9/18)、66.7%(4/6)和100%(3/3)。结论对反复出现的肉眼血尿、腰痛和肾积水患者要考虑输尿管癌的可能,联合应用几种检查方法是提高诊断率的关键。

Objective To improve the diagnosis of primary ureteral carcinoma.Methods A total of 22 patients with primary ureteral carcinoma were hospitalized from March 1993 to May 2010,and their clinical data were retrospectively analyzed.Results Seventeen patients were clinically manifested as hematuria,10 as lumbar pain,and 14 as hydronephrosis.The useful examinations with high positive rate of diagnosis included retrograde pyelography,computerized tomography,magnetic resonance imaging,and ureteroscopy,with positive rate of diagnosis being 72.7%（8/11）,38.9%（7/18）,66.7%（4/6）,and 100%（3/3）,respectively.Conclusion A patient with repeated hematuria,lumbar pain and hydronephrosis might be considered as ureteral carcinoma.The combination of several detecting methods is of vital importance to improve its diagnosis level.
