Assessed the usefulness of virtual cystoscopy performed with multidetector computed tomography (CT) in patients with different urinary bladder pathologies compared to the conventional cystoscopy.
Eighteen patients with different bladder pathologies, which consisted of 11 tumors, 3 diverticula, 2 trabecular changes and 2 stones, were assessed with conventional cystoscopy and virtual CT cystoscopy. The results of virtual CT cystoscopy were compared with the findings of conventional cystoscopy. We determined the detection rate and positive predictive value of CT imaging based virtual cystoscopy in the diagnosis of urinary bladder lesions.
CT scanning was well tolerated by all patients, and no complications occurred. Images in 16 (88%) of the 18 virtual cystoscopic examinations were either of excellent or good quality. All tumors except one, 2 trabecular changes and 2 stones were characterized with similar findings in the both of methods. The masses ranged from 0.4 to 7.0 cm in diameter. While conventional cystoscopy could not evaluate interior part of the diverticulum, virtual CT cystoscopy could demonstrate clearly within it. There were no false-positive findings in our series.
Virtual CT cystoscopy is a promising technique to be used in the detection of bladder lesions. It should be considered especially at the evaluation of bladder diverticula. In the future, it may be possible or even advantageous to incorporate into the imaging algorithm for evaluation of bladder lesion.
与传统膀胱镜检查相比，评估多排螺旋计算机断层扫描（CT）虚拟膀胱镜检查在不同膀胱病变患者中的应用价值。
对18例患有不同膀胱病变的患者进行评估，其中包括11例肿瘤、3例憩室、2例小梁改变和2例结石，分别采用传统膀胱镜检查和CT虚拟膀胱镜检查。将CT虚拟膀胱镜检查结果与传统膀胱镜检查结果进行比较。我们确定了基于CT成像的虚拟膀胱镜检查在膀胱病变诊断中的检出率和阳性预测值。
所有患者对CT扫描耐受性良好，未发生并发症。18例虚拟膀胱镜检查中有16例（88%）图像质量为优或良。除1例肿瘤外，所有肿瘤、2例小梁改变和2例结石在两种检查方法中的表现相似。肿块直径范围为0.4至7.0厘米。传统膀胱镜检查无法评估憩室内侧，而CT虚拟膀胱镜检查可清晰显示其内部情况。本研究系列中无假阳性结果。
CT虚拟膀胱镜检查是一种用于检测膀胱病变的有前景的技术。尤其在评估膀胱憩室时应予以考虑。未来，将其纳入膀胱病变评估的成像算法中可能可行甚至具有优势。
