We report a case of pyelonephritis caused by Candida kefyr, which has been previously described as C. pseudotropicalis. The patient who had been having multiple intrarenal stones and ureteral stones for ten years was admitted for fever, left flank pain, and dysuria. In the blood culture, C. kefyr was isolated. These symptoms and signs were successfully resolved with a new antifungal agent, voriconazole. After the resolution of symptoms and signs, the patient took extracorporeal shock wave lithotripsy for intrarenal stones and ureteral stones.
