经腔内彩色多普勒超声对膀胱癌术前分期的诊断价值

Diagnostic value of transvaginal color Doppler ultrasonography in preoperative staging of bladder cancer

目的探讨经腔内彩色多普勒超声对膀胱癌术前分期的诊断价值。方法对129例膀胱癌患者采用经腔内彩色多普勒超声检查,进行术前分期,并与手术、病理诊断结果进行比较。结果 129例膀胱癌患者中,经腔内彩色多普勒超声诊断术前分期为:T_151例、T_220例、T_338例、T_420例;手术及病理分期为:T_1 49例、T_2 23例、T_3 37例、T_4 20例。超声术前诊断膀胱癌分期,T_1期的准确度、敏感度、特异度分别为96.90%、97.30%、96.25%;T_2期分别为94.57%、78.26%、98.11%;T_3期分别为97.67%、97.29%、97.83%;T_4期分别为100%、100%、100%。结论经腔内彩色多普勒超声对膀胱癌术前分期具有较高的临床应用价值。

Objective To investigate the diagnostic value of transvaginal color Doppler ultrasonography in the preoperative staging of bladder cancer. Methods The preoperative tumor staging of 129 patients with bladder cancer was defined by transvaginal color Doppler uhrasonography,then the findings were compared with the results of surgical and pathologic diagnosis. Results In 129 cases of bladder cancer,51 were diagnosis as phase T- ,20 as phase T2 ,38 as phase T3 and 20 as phase T4 by using transvaginal color Doppler uhrasonography for staging, while the results of surgical and pathologic staging were as follows ：49 cases of phase T1 ,23 of phase ＇F2 ,37 of phase T3 and 20 of phase T4. Tire accuracy, sensitivity and specificity of transvaginal color Doppler ultrasonography in the diagnosis of phase T- bladder cancer were 96.90% ,97.30% and 96.25% respectively,of phase T2 were 94.57% ,78.26% and 98.11% respectively,of phase T3 were 97.67% , 97.29% and 97.83% respectively, and of phase T4 were 100% , 100% and 100% respectively. Conclusion Transvaginal cdor Doppler ultrasonography has great value of clinical application in preoperative staging of bladder cancer.
