Abstract:
Presentation of 6 cases of renal cholesteatoma in 4 male and 2 female patients ranging between 30 and 67 years of age. The most consistent clinical data was a history of relapsing nephritic colic of long-evolution. The average time to diagnose was 19 years. In 50% cases an association to malignant neoplastic pathology was found. The clinical diagnosis was based on the urography and the histopathological examination of the material passed with the urine. Renal exeresis was performed in 5 cases. One was treated in a conservative fashion. Also the etiology causes, diagnostic procedure and other therapeutic possibilities were reviewed.
