A Clinical Study and the Diagnosis in Magnetic Resonance Imaging of Renal Scarring

Abstract: Twenty-nine kidneys of seventeen patients (nine boys and eight girls) with vesicoureteral reflux and repeated urinary tract infection were studied by magnetic resonance imaging for diagnosis of renal scarring and correlation between clinical data and the degree renal scarring. Renal scarring is classified into three types according to findings in magnetic resonance imaging. The degree of renal scarring are classified into five grades according to traditional grading of intravenous pyelogram. If a fine deformit… Show more

“…In general, IVU is used for the diagnosis of scar formation and the occurrence of scarring is determined by the detection of deformity of the calices or renal contour and assessment of the size of the kidneys (Smellie ef al., 1975). As shown in this study and our previous study in patients with vesicoureteric reflux (Tsugaya et al, 1989), cortical scarring without caliceal deformity cannot be diagnosed by IVU alone because the scar is seldom located in a position where it can be recognised by this method. It has been generally assumed that acute pyelonephritis usually heals without renal scarring (Smith, 1975), but scarring has sometimes been reported in a considerable percentage of these patients (Meyrier et al, 1989;.…”

“…In 1 patient, pyelonephritis recurred approximately 1 year after the initial CT scan was obtained and the reinfected lesion was in almost the same area as that on the initial CT scans. Cortical scarring and atrophy of the renal parenchyma showed further progression on the follow-up CT scan obtained after reinfection (Tsugaya, 1989). Although it is not possible to draw any general conclusions from experience with one case alone, this was an interesting finding since it suggests that areas once subjected to infection are likely to be reinfected with further scarring and that such a process may lead to the development of extremely fibrous renal scarring.…”
