摘要

The authors offer use of static magnetic resonance urography (MRU) in diagnosing hydronephrotic or obstructed renal pathology as opposed to conventional intravenous urography (IVU). They found that the sensitivity and the specificity of MRU was 95% and 100%, respectively, for finding hydronephrosis, although determining the exact grade of obstruction was not as precise (from 33.3% to 92.6% with increasing grades of hydronephrosis). Calculus disease was only determined in 46.6% of imaging studies, but this review was based on elective imaging only.
