【摘要】 目的　探讨膀胱癌术前分期与术后随访中CT的价值。材料与方法　分析 3 9例膀胱癌CT资料 ,将其分为 4型 ,并与手术、病理对照基底部浸润深度、邻近侵犯和术后复发的表现。结果　乳头状有蒂 5例 ,非乳头状有蒂 6例 ,乳头状宽基底 5例 ,非乳头状宽基底 13例 ;浸润粘膜层 5例 ,粘膜下层及浅肌层各 6例 ,深肌层 5例 ,浆膜或纤维膜及膜外 3例 ;邻近侵犯 16例 ;术后复发 /再发 17例 ,输尿管扩张 8例 ,淋巴结转移 3例。结论　膀胱癌浸润粘膜层与粘膜下层表现相似 ;浅肌层和深肌层受侵可参考间接征象有助于诊断 ;浆膜或纤维膜及膜外受侵时 ,其表面不光滑呈齿状或纤维条索状粘连 ;膀胱癌腔内最常侵犯输尿管入口 ;薄层扫描能显示膀胱壁受侵。更多还原

【Abstract】 Objective To evaluate CT in preoperative staging of primary bladder cancer and in postoperative follow-up. Materials and Methods Based on the CT findings of 39 patients, primary bladder cancers were classified into 4 types. CT signs were compared with pathologic results.Results The findings were as follows: pedunculated papillary carcinoma (n=5), pedunculated non-papillary carcinoma (n=6), broad-basal papillary carcinoma (n=5), broad-basal non-papillary carcinoma (n=13), involvement of the mucous membrane (n=5), the submucous layer (n=6), the superficial (n=6) and deep (n=5) muscular layer, the tunica serosa and fibrosa (n=3) or the adjacent structures (n=16). Recurrence was seen in 17 cases, ureteral dilatation in 8 and lymphatic metastases in 3.Conclusion On CT scan, mucous membrane invasion and submucous layer invasion have the similar appearance. Based on some indirect signs, superficial and deep muscular layer invasion can be diagnosed. When the tunica serosa or the tunica fibrosa is involved, its surface becomes spiculated or serrated. The orifice of ureter is most commonly involved. The invasion of the bladder wall can be displayed on thin-slice scans.更多还原
