目的 评价低浓度造影剂膀胱造影对诊断膀胱小肿瘤的价值。方法 1992～ 2 0 0 1年对 187例膀胱疾病患者 ,在电视的监视下经导管向膀胱内注入 6%～ 8%泛影葡胺约 10 0～ 12 0ml,摄取膀胱前后位及双斜位片 ,必要时摄头低足高位片。结果 187例中 ,检出膀胱肿瘤 10 6例 ,其中瘤体≤ 1.0cm者 8例 ,漏诊 3例 ,检出率为 73 .0 % ,全部经手术及病理证实。 8例中 ,1例为腺癌 ,5例为移行上皮癌 ,2例为乳头状瘤。X线表现为乳头状或菜花样充盈缺损。乳头状瘤及移行上皮癌病灶可有窄基底的蒂 ,当病人变化其体位时 ,肿瘤可有一定的动度。结论 低浓度造影剂膀胱造影是一种经济实用、无创伤的诊断膀胱小肿瘤比较理想的方法
Objective To evaluate the value of low contrast contrast medium contrast-enhanced cystography in the diagnosis of small bladder tumor. Methods A total of 187 patients with bladder diseases were enrolled in this study from 1992 to 2001 with about 10% ~ 120ml intravesical instillation of 6% ~ 8% Film, when necessary, low head high film. Results Among the 187 cases, 106 cases of bladder cancer were detected. Among them, 8 cases with tumor ≤ 1.0 cm, 3 cases missed diagnosis, the detection rate was 73.0%, all confirmed by operation and pathology. Of the 8 cases, 1 was adenocarcinoma, 5 was transitional cell carcinoma, and 2 was papilloma. X-ray showed papillary or cauliflower filling defect. Papilloma and transitional epithelial cancer lesions may have a narrow base pedicle, when the patient changes its position, the tumor may have a certain degree of mobility. Conclusions Low contrast contrast medium cystography is an economical and practical method to diagnose small bladder tumor
