Open publisher page 0 citations

Abstract

Objective To evaluate the role of magnetic resonance urography(MRU) in the diagnosis of upper urinary tract obstruction. Methods MRU was performed for 35 patients suspicous of upper urinary tract obstruction. Results MRU provided high resolution images of the urinary tract.The site of upper urinary tract obstruction and hydronephrosis could be clearly shown. Conclusions MRU, a nontraumatic technique,needs no iodinated contrast medium. It might be widely adopted in the diagnosis of upper urinary diseases.
