摘　　要：目的:探讨经腹部超声(transabdominal ultrasound,TAUS)、经腔内超声(transcavitary ultrasound,TCUS)在膀胱癌术前分期评价中的临床应用价值,为膀胱癌治疗提供更准确的理论依据。方法:选择经手术治疗的膀胱癌患者57例,所有患者在术前进行TAUS和TCUS检查。比较TAUS、TCUS及两者联合使用对膀胱癌T分期的结果,并与术后病理分期对照。结果:术前TAUS、TCUS对膀胱癌T分期的准确率分别为68.4%(39/57)、77.2%(44/57),kappa值分别为0.608(P<0.001)、0.837(P<0.001)。联合使用TAUS与TCUS评价膀胱癌T分期的准确率为84.2%(48/57),kappa值为0.837(P<0.001)。结论:TAUS联合TCUS在膀胱癌术前分期检查中有重要临床价值,可显著提高膀胱癌术前分期的准确率,达到膀胱癌术前精确分期的目的,为膀胱癌精准局部切除、新辅助治疗提供了充分依据。Objective： To investigate the diagnostic value of combination of transabdominal ultrasound（TAUS） and transcavitary ultrasound（TCUS） in preoperative staging of bladder cancer. Methods： A total of 57 patients with pathologically confirmed bladder cancer were detected by both TAUS and TCUS before surgery. The preoperative T staging results of TAUS, TCUS and combination of them were compared with postoperative pathological results. Results： The accuracy of preoperative T staging of bladder cancer was 68.4%（kappa=0.608, P〈0.001） by TAUS, 77.2%（kappa=0.837, P〈0.001） by TCUS, and 84.2%（kappa=0.837, P〈0.001） by combination of TAUS and TCUS. Conclusion： TAUS and TCUS are valuable in the preoperative staging of bladder cancer. The combination of them could improve the accuracy and offer an accurate preoperative staging for local resection and preoperative neoadjuvant radiochemotherapy of bladder cancer.
