An unusual cause of acute obstructive renal failure: ureteral Candida albicans fungus ball

Fungal infections of the upper urinary tract are relatively uncommon, a fun gal bezoar formation beeing a particularly unusual complication. We report a case of acute obstructive renal insufficiency due to bilateral ureteral o bstruction with a C. albicans fungus ball. This infection was predisposed b y a bladder stone and prostatism. Therapy usually consists in percutaneous irrigation with amphotericin B in combination with systemic antifungal agen ts. In this case, complete resolution of the obstruction was achieved by tr eatment with forced diuresis and oral fluconazole.
