【摘要】 目的比较CO2气膀胱镜技术和传统膀胱镜检查在膀胱肿瘤诊断中的应用价值。方法 70例膀胱肿瘤患者分为3组:A组22例,行CO2气膀胱镜检查;B组16例,行传统膀胱镜检查,C组32例,两者联合应用,比较3组操作成功率、活检与手术病理诊断的符合率、多发性膀胱肿瘤镜检与手术诊断病灶数目的符合率。结果 A、B、C组操作成功率相仿(100.0%vs.93.7%vs.100.0%)(P>0.05)。C组病检符合率100.0%,明显高于A组的90.9%和B组的93.3%(P<0.05)。C组多发性膀胱肿瘤镜检与手术诊断病灶数目符合率100.0%,亦明显高于A组的85.7%和B组的80.0%(P<0.05)。结论与传统膀胱镜技术相比,CO2气膀胱镜技术用于膀胱肿瘤的检查与诊断并无优势;两者联合应用可以明显提高膀胱肿瘤检查的诊断准确率。更多还原

【Abstract】 Objective To compare the value of CO2 gas cystoscopy with conventional cystoscopy in the diagnosis of bladder tumor.Methods A total of 70 patients the bladder tumor was assigned into three groups of A(22 cases,underwent CO2 gas cystoscopy),B(16 cases,underwent conventional cystoscopy) and C(32 cases,underwent both of them).To compare The success rate of operation and the accordance rate between biopsy and surgical pathological diagnosis,and the number of microscopic examination and surgical diagnosis in multiple bladder tumors were compared among three groups.Results The success rate of operation was similar among groups of A,B and C(100.0% vs.93.7% vs.100.0%)(P>0.05).The diagnose accordance rate in group C was 100.0%,which was higher than 90.9% in group A and 93.3% in group B(P<0.05).The accordance rate in the number of multibladder tumors reported by cystoscopy and surgery in group C was 100.0%,which was higher than 85.7% in group A and 80.0% in group B(P<0.05).Conclusion The CO2 gas cystoscopy is not particularly superior to the conventional cystoscopy for the examination and diagnosis of bladder tumors,but combined use of both techniques can improve the accuracy rate in the diagnosis of bladder tumors.更多还原
