Accurate evaluation of local extent in bladder cancer is important to determine the optimal therapeutic strategy and to predict the outcome of treatment. The purpose of this study is to evaluate the accuracy of 3D volumetric reconstructed US in the assessment of tumor detection and serosal invasion in patients with bladder cancer.
A total of 14 patients with findings of bladder cancer determined with the use of cystoscopy was examined with the use of bladder two-dimensional (2D) US and subsequent 3D US. US findings were compared with cystoscopy findings and the pathological stage after a TURB or a radical cystectomy in a double-blinded manner.
The sensitivity of preoperative tumor staging was 67.9% for 2D US and sensitivity was 78.6% for 3D US. 3D US was superior sensitivity than 2D US (P < 0.05). The accuracy for serosal invasion in staging of bladder cancer was demonstrated for 88.9% in 2D US and for 100% in 3D US.
The accuracy for serosal invasion (T3b) in the staging of bladder cancer was demonstrated for 88.9% in 2D US and for 100% in 3D US. 3D volumetric reconstructed US is a non-invasive and accurate technique for tumor detection of bladder cancer.
准确评估膀胱癌的局部范围对于确定最佳治疗策略和预测治疗结果至关重要。本研究的目的是评估三维容积重建超声在膀胱癌患者肿瘤检测和浆膜侵犯评估中的准确性。
对14例经膀胱镜检查确诊为膀胱癌的患者进行膀胱二维超声及随后的三维超声检查。超声检查结果与膀胱镜检查结果以及经尿道膀胱肿瘤切除术（TURB）或根治性膀胱切除术后的病理分期进行双盲比较。
二维超声术前肿瘤分期的敏感性为67.9%，三维超声的敏感性为78.6%。三维超声的敏感性高于二维超声（P<0.05）。二维超声对膀胱癌分期中浆膜侵犯的准确率为88.9%，三维超声为100%。
二维超声对膀胱癌分期中浆膜侵犯（T3b）的准确率为88.9%，三维超声为100%。三维容积重建超声是一种用于膀胱癌肿瘤检测的无创且准确的技术。
