经尿道腔内超声在膀胱肿瘤诊断和分期中的价值

目的　探讨经尿道腔内超声在膀胱肿瘤诊断和分期中的价值。　方法　总结 70例膀胱癌患者经尿道腔内超声诊断及分期的结果 ,并与膀胱镜、经腹壁超声、CT、MRI、术后病理结果对比。　结果　经尿道腔内超声肿瘤检出率 99.1% ,高于膀胱镜和经腹壁超声检出率 ;膀胱肿瘤分期与病理符合率 :T110 0 .0 %、T2 95 .8%、T3 82 .4 %、T45 5 .6 %。　结论　经尿道腔内超声能清晰显示早期膀胱肿瘤及其浸润深度 ,是早期膀胱肿瘤诊断及分期的重要方法之一

Transurethral ultrasonography in the diagnosis and staging of bladder tumor

Objective To evaluate transurethral ultrasonic scanning in the diagnosis and staging of bladder tumor. Methods Form 1996 to 2000 transurethral ultrasonography(TUUS) was carried out for 70 cases of bladder cancer and the findings were compared with cystoscopy,transabdominal ultrasonography(TAUS),CT,MRI and pathological studies. Results The diagnosis rate of TUUS has been 99.1% being better than cystoscopy and TAUS.The accurate staging rate was 100.0% in stage T 1 tumors, 95.8% in stage T 2,82.4% in stage T 3 and 55.6% in stage T 4. Conclusions TUUS can clearly reveal the depth of tumor infiltration and therefore is an important method for the diagnosis and staging of early bladder tumor.
