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 suspicious 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.
