对经手术和病理证实的８３例膀胱肿瘤进行超声显像和膀胱镜检查的对比性分析。结果表明，膀胱镜对膀胱肿瘤的诊断符合率为９７．５％，略高于超声显像符合率的９５．２％；但对膀胱肿瘤的术前分期，膀胱镜检查尚存在局限性，而超声显像可弥补膀胱镜检查的不足。本文超声显像对膀胱肿瘤的术前分期准确率达８９．５％。超声显像对小于０．５ｃｍ的小膀胱肿瘤之检出率不如膀胱镜高。因此在常规检查以及对肿瘤的术前分期时，应以超声显像作为首选，同时结合膀胱镜检查，可进一步提高膀胱肿瘤的术前诊断正确率。
83 cases of bladder tumors confirmed by surgery and pathology were compared by ultrasound imaging and cystoscopy. The results showed that the coincidence rate of cystoscopy to bladder cancer was 97.5%, which was slightly higher than 95.2% of the coincidence rate of ultrasound imaging. However, the preoperative staging and cystoscopy of bladder tumor were still limited, Ultrasound imaging can make up for the lack of cystoscopy. Ultrasound imaging of bladder tumor in this preoperative staging accuracy rate of 89.5%. Ultrasound imaging of less than 0.5cm small bladder tumor detection rate as cystoscopy high. Therefore, routine examination and preoperative staging of tumors should be the first choice for ultrasound imaging, combined with cystoscopy, can further improve the accuracy of preoperative diagnosis of bladder cancer.
