PATIENTS AT HIGH RISK FOR UPPER TRACT UROTHELIAL CANCER: EVALUATION OF HYDRONEPHROSIS USING HIGH RESOLUTION MAGNETIC RESONANCE UROGRAPHY

MRU is a valuable noninvasive investigation for evaluating hydronephrosis in this group of patients with suspected urothelial cancer in which routine investigation had failed to provide clinically important information. Focused high resolution T2-weighted images were reliable in the diagnosis of ureteral and renal pelvic TCCs, and were valuable in excluding these and other mass lesions as the cause of hydronephrosis.
