Magnetic resonance urography in the assessment of hydronephrosis and hydroureter in children

G. Hadjidekov

Abstract. MR urography is a new, modern modality for evaluation of various urologic abnormalities in children. The goal of this article is to describe the role of MR urography in the assessment of hydronephrosis and hydroureters. MRU is most commonly applied to the evaluation of hydronephrosis and provides valuable insight into a wide range of obstructive uropathies. In our study we investigate 96 children with suspected abnormalities of the upper urinary tract. Using static and excretory MR urography we obtain both morphological and functional information by means of different sequences with or without injection of gadolinium. MR urography is promising diagnostic method of wide spectum of pathological conditions affecting the urinary tract with potential to revolutionize uroradiology imaging in children. It integrates exquisite anatomical information with a variety of functional data and avoids ionizing radiation. MRU is increasingly employed as a problem solver when conventional imaging studies remain inconclusive and overcomes a lot of their limitations with the potential to become in the future leading modality to diagnose diseases of the kidney especially in newborns and children.
