Maybe. Likely not.
You may see Candida growing because of a chronic in-dwelling urinary catheter, instrumentation/urologic procedures, contamination, or because of a true UTI or even bloodstream infection.
If the patient has a catheter, remove it and see if the Candida persists. If it cannot be removed, replace it with a new one.
Asymptomatic candiduria should only be treated in high-risk populations: neutropenic patients and those undergoing surgery or urinary tract procedures. Also, if the patient has dysuria, then it should be treated. Most strains are susceptible to fluconazole so this is a first-line agent.
