采用介入性实时超声显象仪,经尿道对8例14枚膀胱移行上皮肿瘤按照超声分期标准作检查分期。其中U_1者1枚,U_2者8枚,U_3者4枚,U_4者1枚。与临床及病理检查的分期对照,仅1枚超声为U_3超过病理的T_2者外,余均相符。作者认为经尿道膀胱腔内超声作为膀胱镜的一种补充,是膀胱肿瘤术前分期较为可靠的方法。 Using interventional real-time ultrasound system, transurethral resection staging was performed in 8 cases of 14 bladder transitional epithelial tumors according to the standard of ultrasound staging. Among them, one is U_1, eight are U_2, four are U_3 and one is U_4. Compared with the clinical and pathological examination of staging, only one ultrasound U_3 over the pathological T_2, the remaining are consistent. The authors believe transurethral ultrasound as a complement to cystoscopy is a more reliable method of preoperative staging of bladder cancer.
