CT evaluation of cases with renal and perirenal infections

ABSTRACT

Twenty five patients, 19 males and 6 females with age between 6-81 years complaining of signs and symptoms of renal and perirenal infections were evaluated by computed tomography. Nine patients were found to have renal abscesses, 5 pyonephrosis and 3 primary perirenal abscesses. The evidence of focal or multifocal interstitial bacterial nephritis was demonstrated in 6 patients and xanthogranulomatous pyelonephritis in 2. Thickening of Gerota's fascia with or without perinephric fluid collections as a result of renal infection were encountered in 11 cases. In 2 cases, bilateral renal involvement was noted with evidence of chronic pyelonephritis in one kidney and acute nephritis in the other. CT proved to be a sensitive diagnostic tool for evaluating renal and perirenal infections
