ABSTRACTBackground: Xanthogranulomatous pyelonephritis (XGP) is a rare form of chronic infection of the kidneys and the retroperitoneal spaces. It happens in approximately 0.6 % of the cases of pyelonephritis, this documented by an anatomopathological study. The disease was described for the first time by Slagenhaufer in 1916.
Objective: To analyze the clinical aspects of this rare variant of pyelonephritis, to know more about it.
Methods: Seven patients were studied with the anatomopathological diagnosis of XGP from January of 2000 to October of 2005. They were studied in the “Dr. Jose Eleuterio Gonzalez” University Hospital.
Results: Six of the seven patients were female and only one male, with ages between 29 to 50 years. Three patients were found to be diabetic, one had a history of urolithiasis, one of obesity and 2 did not have any relevant past medical history. The triggering factors were lithiasis in 5 patients, carcinoma of the ureter in another patient and in the other patient there was no apparent cause.
Conclusion: XGP is a benign renal affection and unfortunately the clinical presentation is not specific and does not have a certain and defined time to establish itself.
