Abstract

Magnetic resonance imaging (MRI) of kidneys was performed prior to extracorporeal shock wave lithotripsy (ESWLT), within 48 hours of treatment (immediate), and three months post-ESWL (intermediate) in 14 patients. Five patients underwent bilateral treatments for a total of 19 treated kidneys. With the pre-ESWL study serving as a control, immediate and intermediate examinations were evaluated for changes in renal volume, development of abnormalities in the corticomedullary junction (CMJ), development of intrarenal, subcapsular, or perinephric fluid, and alterations in the perinephric tissue and renal fascia. A statistically significant increase in renal volume occurred in the immediate post-ESWL period. This increase may have been secondary to parenchymal interstitial edema which resolved within three months. Thirty-two percent developed subcapsular bleeding and fascial and perinephric tissue prominence. All abnormalities identified on the immediate studies attributable to the ESWL treatment had resolved by the three-month study. No new cases of hypertension had developed within a three-month follow-up period.
