THE ROLE OF MRU IN PATIENTS WITH OBSTRUCTIVE UROPATHY

Abstract

MRassumes an expan ing role as diagnostic -step in evaluation of the patients with urinary tract obstruction as a non invasive procedure

This study was carried on 106 patients with urinary tacf obstruction who underwent US and MRU in all the cases using HASTE technique in 21 patient and respiratory triggering 3D with reconstructed MIP image in the rest of the cases .The study population was classified into 5 separate groups according to the cause of obstruction,

The technique _accurately identified urinary tract dilatation in all• patients ,the exact site of obstruction in 99% and cause of obstruction in 94 % of the cases

The technique was more accurate than other imaging modalities in diagn<_:>sis of obstructive uropathy except in calcular group where Spiral CT was better

The technique may prove viable alternative to IVP and CT in diagnosis of urinary tract obstruction

In conclusion MRU give an excellent morphological delineation of the urinary tract
