Introduction. Although conventional cystoscopy is considered to be the gold standard for diagnosis and follow-up of bladder tumors, it remains an invasive and costly procedure. With the advent of the multidetector CT (MDCT) scanners supported by specialized software virtual cystoscopy (VC) is possible. We assess the role of VC in diagnosing and evaluating bladder lesions. Materials and Methods. Between September 2010 and October 2011, 25 consecutive patients with cystoscopically confirmed bladder tumor underwent VC. The radiologists involved in this prospective study were blinded to the exact findings. After draining any residual urine with a catheter, the bladder was retrogradely insufflated with 200-600 cc of air. No intravenous or intravesical contrast was used. MDCT scan was performed in supine and prone positions and three-dimensional reconstruction of the urinary bladder was performed. Results. The examination was well tolerated by all patients with no complications. In total, 43 lesions were detected both with conventional cystoscopy and VC. Tumor size measured by CT ranged from 3 to 80 mm in diameter. The pathological report revealed noninvasive transitional cell carcinomas in all cases. Conclusion. VC has promising results in detecting exophytic bladder lesions. In the future it could be part of the diagnostic algorithm for bladder tumors.
引言。尽管传统膀胱镜检查被认为是膀胱肿瘤诊断和随访的金标准，但它仍然是一种侵入性且成本高昂的检查方法。随着配备专门软件的多排螺旋CT（MDCT）扫描仪的出现，虚拟膀胱镜检查（VC）成为可能。我们评估了VC在诊断和评估膀胱病变中的作用。材料与方法。在2010年9月至2011年10月期间，25例经膀胱镜检查确诊为膀胱肿瘤的连续患者接受了VC检查。参与这项前瞻性研究的放射科医生对确切的检查结果不知情。用导管排出所有残余尿液后，向膀胱逆行注入200 - 600 cc空气。未使用静脉或膀胱内造影剂。在仰卧位和俯卧位进行MDCT扫描，并对膀胱进行三维重建。结果。所有患者对该检查耐受性良好，无并发症发生。总共通过传统膀胱镜检查和VC检查发现了43个病变。CT测量的肿瘤大小直径范围为3至80毫米。病理报告显示所有病例均为非侵袭性移行细胞癌。结论。VC在检测膀胱外生性病变方面有良好的结果。未来它可能成为膀胱肿瘤诊断算法的一部分。
