Computerized tomography virtual endoscopy in evaluation of upper urinary tract tumors: initial experience.

Purpose: To assess the usefulness of CT virtual endoscopy (VE) as an integration of CT-urography, for the detection of upper urinary tract tumor in patients with hematuria.

Materials And Methods: Fourteen patients with hematuria and high risk of transitional cell carcinoma of the upper urinary tract underwent urinary cytology, ultrasonography, excretory urography, cystoscopy, CT-urography with VE, and optical ureteroscopy. The CT urograms and VE were correlated with the pathological findings of surgical specimen (6/14) and cytological examination of ureteroscopy biopsy (8/14).
