CT膀胱仿真内窥镜的临床应用

Clinical application of CT virtual cystoscopy

目的总结CT膀胱仿真内窥镜（CTVC）的临床应用，探讨其临床应用的意义。方法对具有临床指征的13例患者，在膀胱排空后静脉推注造影剂，待膀胱充盈后行膀胱区域的薄层螺旋CT扫描，采集数据进行后期处理。应用三维导航软件建立CTVC图像。全部病例均有膀胱镜对照检查资料，并将检查结果结合手术、病理结果作对照分析。结果13例患者中诊断为膀胱肿瘤9例，良性前列腺增生3例（合并膀胱憩室1例），腺性膀胱炎1例，CTVC检查漏诊腺性膀胱炎1例，其余疾病均获得正确诊断。CTVC总诊断符合率92.3％，膀胱肿瘤临床诊断符合率100．0％。结论CTVC在显示膀胱腔内病变方面具有较好的敏感性，作为非侵入性诊断方法，具有较好的临床应用价值。

Objective To evaluate the clinical application of CT virtual cystoscopy （CTVC）. Methods Thirteen patients who had clinical indication were studied. Iodine contrast was intravenously injected after the bladder was voided. Thin-slice spiral CT scanning of the bladder area was started when the bladder became filled with contrast media. By using 3D navigator smooth software, CTVC images were obtained. The findings in all eases were compared with the cystoseopy and surgical results. Results Nine patients with CTVC were proved vesieal tumor,3 patients with CTVC were proved benign prostatic hyperplasia, and they were confirmed by cystoscopy,1 patient with cystitis glandularis could not be diagnosed with CTVC.By CTVC, the diagnostic accordance rate was 92.3%,the coincidence rate was 100.0% in vesical tumor. Conclusigns CTVC is highly sensitive in displaying the vesical lesions.Being a new and non-invasive technique, CTVC is very helpful in the diagnosis of introvesical diseases. It has fine value in the clinical practice.
