Funguria, fungal urinary tract infections, are most commonly caused by Candida species but may also be caused by Cryptococcus neoformans, Aspergillus species, and the endemic mycoses. Candiduria presents as an increasingly common nosocomial infection, which may involve all anatomic levels of the urinary tract, resulting in a spectrum of disease varying from asymptomatic candiduria to clinical sepsis. Although several successful systemic or local therapeutic options exist for the eradication of candiduria, knowledge of the pathogenesis and natural history of candiduria has lagged. This has resulted in confusion among practitioners as to when antifungal therapy is indicated. Treatment guidelines have recently been formulated and are described herein.
