XANTHOGRANULOMATOUS PYELONEPHRITIS AND SEGMENTAL DILATATION OF URETER : A RARE ASSOCIATION

Xanthogranulomatous pyelonephritis (XGP) is an atypical form of chronic pyelonephritis characterized by diffuse, focal or segmental suppurative destruction of renal parenchyma. Segmental dilatation of ureter is characterized by a giant, focal segmental dilatation of mid ureter. We report a child who had duplication of the kidney with segmental dilatation of both upper and lower moiety ureters. The lower moiety was non-functioning and showed structure of xanthogranulomatous pyelonephritis on histology. These associations were not reported earlier.
