Evaluation and treatment of urinary candidiasis

The incidence of genitourinary fungal infections is increasing, and because of their lethal potential, early diagnosis and treatment is mandatory. Candida is the most common urinary fungus and is manifest as renal involvement from systemic candidiasis, primary renal candidiasis, bezoar formation, cystitis, and as asymptomatic candiduria. The clinical status of the patient, serial urine cultures, excretory urogram, and serum candidal titers help to differentiate between the various disease states. Treatment is specific and is based on the clinical manifestation of the disease. Systemic candidiasis is treated with intravenous amphotericin. Fungal bezoars are best treated with oral flucytosine, ureteral and renal irrigation with amphotericin and, occasionally, operation. Cystitis is treated with oral flucytosine or amphoteric bladder irrigations. Asymptomatic candiduria is left untreated. A systematized evaluation and treatment regimen is presented.
