[MR urography in the diagnosis of upper urinary tract obstruction].
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.
