Do Infection-Associated Stone Subtypes Behave the Same Clinically? A Retrospective Bicenter Study.

The clinical implications of these two different, but closely related stone types, are unknown. We sought to compare the clinical, microbiologic, and metabolic characteristics of patients with MAP and CA stone types.
