Urosepsis From Nephrolithiasis Caused by Candida glabrata: A Rare Etiology of Urinary Sepsis in an Immunocompetent Patient

Nephrolithiasis can often serve as an infection nidus, as it is typically associated with urease-producing bacteria and can obstruct the urinary tract, leading to pyelonephritis. While most urinary tract infections from septic stones are bacterial in etiology, fungal causes are less commonly reported in immunocompetent patients and rarely manifest as fungemia. Among fungal causes, <i>Candida albicans</i> is the most common. We describe the case of a 41-year-old immunocompetent patient with a history of recurrent kidney stones and percutaneous nephrostomy tube placement, who developed sepsis from a urinary source secondary to a nephrolithiasis. Blood culture isolates grew <i>Candida glabrata</i>. Following identification of the fungus, the patient received a two-week intravenous micafungin course and outpatient stone removal per urological surgery.
