[Spiral CT urography and CT virtual endoscopy in detecting urological diseases].
OBJECTIVE
To evaluate spiral CT urography (SCTU) and CT virtual endoscopy (CTVE) in detecting urologic diseases.


METHODS
SCTU was performed in 46 patients with urological diseases including renal neoplasms (2), paropelvic cysts (2), ureteral calculi (6), ureteral stenosis (4), ureteral neoplasms (2), double kidneys and ureter malformation (1), bladder neoplasms (28) and bladder endometreosis (1). The 6 patients with ureteral diseases and 29 patients with bladder diseases underwent CTVE based on spiral CT scan. All CTVE findings were compared with those of B-mode ultrosonography, intravenous urography (IVU), retrograde pyelography (RGP), conventional CT or cystoscopy.


RESULTS
All upper urinary tract diseases and bladder diseases (28 cases) were detected by SCTU and CTVE scans and they were confirmed operatively or pathologically except one case of bladder neoplasm (diameter less than 5 mm) was missed.


CONCLUSIONS
SCTU and CTVE have proved to be non-invasive and reliable in the diagnosis of urological diseases and are superior to IVU or conventional CT. CTVE can serve as a supplementary method to fiberoptic cystoscopy or ureteroscopy.
