RESUMO
We present our 4-year experience on the preoperative diagnosis of renal xanthogranulomatosis by sequential urinary cytology. The usefulness of this method is evident due to the absence of any other possible means of preoperative diagnosis of this disease. The possibility of obtaining foam cells by ureteral catheter washouts and translumbar aspiration in the patients, where spontaneous urine cytologies were negative, is also pointed out.

The search for foam cells in the urinary sediment of patients with possible renal xanthogranulomatosis can constitute a harmless and useful diagnostic method for this frequently occurring renal disease, which previously has been diagnosed with certainty only by histological examination or biopsy. Of 5 cases studied the search was positive in 80 per cent.
