The Possibilities of Computed Tomography in the Diagnostic Cancer of Upper Urinary Tract
Abstract
Objective. To evaluate the possibility of computed tomography in the diagnostisc and staging of cancer of the upper urinary tract (UUT).
Material and methods. The study included 23 patients with cancer of the upper urinary tract. All patients underwent contrast-enhanced MSCT, urine cytology (to detect atypical cells or cancer cells). Upon detection of the tumor of UUT according to MSCT, patients underwent ureteropieloscopy with a biopsy. After the surgery was performed to verify the diagnosis histological examination of surgical material.
Results. The leading computer-tomographic finding of UUT cancer is a “defect” in renal pyelocaliceal system, in the ureter in the excretory phase. MSCT allows exactly speak about cancer in the case of accumulation of contrast material, can detect even small-sized neoplasm in patients without an extension renal pyelocaliceal system. Systematized and formulated a computer-tomographic signs of staging of malignant tumors of the UUT.
Conclusion. MSCT is the most effective diagnostic method of upper urinary tract cancer, and the method allows to establish the stage of disease.
