Abstract
The diagnosis of urinary tract obstruction depends on showing increased resistance to flow along the urinary tract. Such increased resistance causes proximal dilatation (obstructive uropathy) and secondary functional effects on the kidney (obstructive nephropathy) with associated nephron damage and parenchymal atrophy (obstructive atrophy) [1]. Ultrasonography (US), intravenous urography (IVU), computed tomography (CT) and magnetic resonance imaging (MR) diagnose obstruction largely by showing the anatomical consequences of obstruction, namely the dilatation of the pelvicalyceal system and ureter proximal to the obstructing lesion. Some limited functional information may be obtained from the pattern of contrast medium excretion with IVU, CT and MR and from Doppler US examination. Scintigraphy, however, provides direct functional evidence of obstruction.
