Mortality from grossly encrusted bilateral pyelitis, ureteritis, and cystitis by Corynebacterium group D2.

This is the first report of death due to gross encrustations of the entire upper urinary tract and bladder by Corynebacterium group D2 in a man with no history of renal transplantation or prolonged catheterizations. This case demonstrates that debilitated patients with a prior endoscopic procedure are at risk for this disease process. Prolonged treatment with appropriate antibiotics, acidification of the urine, and removal of crusts is essential for proper management.
