| 目的 评价螺旋CT增强扫描对上皮性膀胱肿瘤分期的价值。方法 53例上皮性膀胱肿瘤,其中50例行手术切除或电切。病理诊断移行上皮癌51例,乳头状腺瘤和低分化鳞癌各1例,术前1周内行盆腔螺旋CT平扫和增强扫描,6例追加延迟充盈相扫描。结果 CT显示膀胱壁局限性肿物或不规则增厚,轻到中度强化;T1期6/7例、T2期2/15例显示肿瘤基底强化线,T3、T4期基底强化线,提示肿瘤已侵犯外肌层。结论 基底强化线对上皮性膀胱肿瘤分级有较高的准确性。 |

| Objective To investigate the value of contrast helical CT in staging epithelial bladder neoplasm. Methods Total 53 female patients with epithelial bladder neoplasm confirmed pathologically underwent plain and contrast helical CT scan within one weak before surgery or biopsy, including 51 cases of transtional epithelial cancer, 1 case with papillary adenoma and another case with poorly differentiated squamous cell carcinoma. Delayed CT scan was performed in 6 cases in filling phase. Results The helical CT diagnosis of epithelial bladder neoplasm based on local mass or irregular thickening of bladder wall, mild to moderate degree of enhancement. The enhanced basic line could be seen in 6 of 7 T1 cases and in 2 of 15 T2 cases, but none in T3 and T4 cases, which indicate tumor invading of out layer of muscles in T3 and T4. Conclusion The enhanced basic line is helpful in staging of the epithelial bladder neoplasm. |
