Role of Virtual CT Cystoscopy versus

Bladder neoplasms are common around the world. Incidences are particularly high in the Nile River Valley secondary to Schistosomiasis which is frequently associated with development of squamous cell carcinoma (Cohen et al., 2000).The urinary bladder is a good candidate for virtual endoscopy because of its simple luminal morphology, its relatively small volume, and the absence of involuntary peristalsis. Therefore, a virtual cystoscopic rendering of the bladder takes a short time to navigate and does not require that the operator have great skill (Kim et al., 2002).Fifty patients (“40 males; 10 females” their age ranges from 40-80 years with their mean 44.3 years) with bladder tumors were enrolled in this study, they were conducted at the Radiology Department, Zagazig University Hospitals between May 2005 and May 2007. Our patients were referred from General Surgery, Urology Departments and Outpatient clinics.All patients were examined with spiral helical CT and MR. Also, all the patients were examined with virtual cystoscopy with IV contrast while 44 patients out of them were examined with pneumocystoscopy as the rest 6 patients either refuse catheterization or had difficulty to have prone position.Our study included 35 patients with urothelial carcinoma, 13 patients had squamous cell carcinoma, one case had benign tumors and the last case had mesenchymal tumor.In our study the lesions were staged in 49 patients pathologically as follow: 17 patients with pTa-pT1, 6 patients with pT2a, 9 patients with pT2b, 13 patients with pT3 and 4 patients with T4.
