This chapter aims to discuss about the fungal urinary tract infections. Fungal infections are classified either according to epidemiology or by anatomic site of involvement. The commonly used epidemiologic categories classify fungal infections as either opportunistic or endemic. Fungal infections can also be classified by the site of involvement into either mucocutaneous, which can cause serious morbidity but are rarely fatal or into deep organ infections which is serious fatal illness. Clinical presentation alone cannot differentiate between bacterial and fungal UTI and the presentation may range from asymptomatic candiduria to full blown sepsis in patients with candidemia. Candiduria, the shedding of the fungi in urine, is seen in a spectrum of clinical situations. Epidemiology, pathogenesis, diagnosis, management, and aspergillus urinary tract infection are also provided in this chapter.
