Unexpected candidemia complicating ureteroscopy and urinary stenting

Two elderly patients with obstructive renal calculi who developed Candida albicans bloodstream infection within 12 h following ureteroscopy and ureteral stenting are described. Both patients were treated with prolonged courses of broad-spectrum antibiotics and were found to have urine cultures positive for Candida albicans prior to the urologic procedures. One patient also developed bilateral candidal endophthalmitis. The clinical presentation was indistinguishable from bacteremia complicating manipulation of the urinary tract. The patients were successfully treated with systemic antifungal therapy. Candiduria may present a risk for dissemination during invasive, relatively simple urologic procedures.
