Background: Calcium-based urinary stones rarely grow bacteria on stone culture. The presence of an anaerobic bacteria is even more uncommon. We present a case of Veillonella growth from a primarily calcium phosphate-based urinary stone culture. Case Presentation: A 56-year-old Caucasian woman presented with urosepsis and bilateral nephrolithiasis. A nephrostomy tube was emergently placed in the left kidney. After resolution of her urosepsis, she underwent a left percutaneous nephrolithotomy. The stone culture grew Veillonella , a gram-negative anaerobe. Conclusion: Growth of anaerobic bacteria, such as Veillonella , on stone culture of a calcium-based stone is a rare occurrence; the mechanism of this association remains unexplained.
