“…Therefore, a virtual cystoscopic rendering of the bladder takes a short time to navigate and does not require great skill on the part of the operator (4)(5)(6)18). On the other hand, according to a study by Kim et al, virtual cystoscopy was found superior than multiplanar reconstruction and source CT images for lesion detection in the contrast material-filled bladder (22). However, most stud- sidering conventional cystoscopy to be the gold standard, we found the following diagnostic values for the identification of bladder lesions on virtual cystoscopy.…”

Objective: Assessed the usefulness of virtual cystoscopy performed with multidetector computed tomography (CT) in patients with different urinary bladder pathologies compared to the conventional cystoscopy. Materials and Methods: 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. Results: 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. Conclusion: 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.

“…In this method, there is no need for examination in prone and supine position. Therefore, this means lesser radiation and cost (3,22). However, urine and contrast could not be mixed properly with this method for virtual cystoscopy.…”

“…Our findings are also consistent with previous reports. For example, Nerumi et al [22] identified only 70% of lesions <1 cm by using a single-detector-row scanner with 3-mm collimation, and Kim et al [23] identified 82% of lesions <5 mm using a four-detector-row scanner and 1.25-mm collimation. In contrast, in a study conducted with a 16-detector-row scanner and 3-mm collimation, Song et al [18] defined CTC with VC an unreliable technique for detecting lesions <5 mm (only 60% of lesions detected).…”
