Objectives: To determine the diagnostic performance of virtual cystoscopy in patients with bladder diseases in comparison with conventional cystoscopy.
Methods: Fifteen patients with different bladder pathologies underwent volumetric spiral CT of bladder after filling it with contrast media (GE medical system light speed multislice scanner). The data were transferred to Advantage workstation AW4.0-03 and virtual cystoscopy was performed using the special software (Navigator GE medical system). All the patients later underwent conventional cystoscopy and the findings of both investigations were compared.
Results: Virtual cystoscopy detected all 10 lesions with >5mm size and missed I out of 3 lesions with 5 5mm size. The overall sensitivity was 90%, specificity was 100%, positive predictive value was 100% and negative predictive value was 83.3%. The average time taken per procedure was 8 minutes. No complications of virtual cystoscopy were encountered in our study.
Conclusions: There seems to be good agreement as regards the site and size of lesions in both techniques. In the quest for a non-invasive investigation for assessment of bladder diseases, virtual cystoscopy is a promising technology. |
