膀胱肿瘤的超声图像与病理35例报告

Ultrasonic Images and Pathology of Cystoma

就我院1994年～1997年经手术、病理证实为膀胱肿瘤35例的B超图像与病理进行分析，以提高诊断水平．膀胱肿瘤的回声基本上分为向膀胱腔突起和向膀胱壁浸润两部分．充盈的膀胱无回声暗区内有明亮的菜花样或乳头状凸起，肿瘤生长部位膀胱壁回声零乱不清．部分可见侵及肌层．35例均具有上述声像．其中31例为移行上皮癌．着重分析了4例膀胱肿瘤超声误诊为前列腺不规则增生、血块机化、输尿管癌、膀胱壁增生的超声声像及误诊原因，对照手术及病理所见，提出注意事项及检查手法，对原因不明血尿或膀胱刺激症状者，均应进行超声检查，其与CT、膀胱镜、膀胱造影等有很好的互补性．

Cystoma has high morbidity in urinary system. For improving the diagnostic level, thisarticle retrospeCtively analpsed ultrasonic images of 35 patients with cystoma who were undergone B-typeultrasonography and tertified by surgical operation and pathological diagnosis from 1994～1997. Basicimage of cystoma was characterized by expansive growth and infiltrating growth, The papillary tumor wasconvex from the unregular bladder wall to the filled dark bladder ventricles, some invaded the smoothmuscle layer. All the 35 cases had the previously mentioned characters, and 31 cases were pathologicallydiagnosed as transitional cell carcinoma. This article emphasized the US images and misdiagnostic reasonsof 4 cases, who were misdignosed as unregular prostatic hyperplasia, hematoma organization, ureter can-cer and bladder wall proliferation. Comparing with surgical pathological diagnosis, we considered moreattentions be paid to the examination skill. We concluded that those who had unknown-reason hematuriaor bladder irritative symptom should be firstly undergone ultrasonography, which is compatible with CT,cystoscopy and cystography.
