Approximately 10% of symptomatic urinary tract infections in young adult women are caused by Staphylococcus saprophyticus, a novobiocin-resistant, coagulase-negative Staphylococcus that synthesizes urease (1, 2). Recurrent infection due to S. saprophyticus occurs in approximately 10% of patients after appropriate antimicrobial therapy (1, 3). We report the case of a patient with a struvite urinary calculus infected by S. saprophyticus that apparently was the cause of recurrent staphylococcal bacteruria.
A 31-year-old white woman had a recent onset of urinary frequency and dysuria. She was pregnant but had had no previous urologic disorders. A midstream urine specimen taken on 12 March 1982
