Funguria-Introduction, Common fungi, Clinical Feature, Lab Diagnosis, Treatment, and Prevention

by
Urine sample for fungal culture and KOH mount

Introduction Funguria refers to the presence of fungi in the urine, either due to colonization, contamination, or true urinary tract infection (UTI). It is increasingly reported in hospitalized or catheterized patients, particularly those with immunosuppression, antibiotic overuse, or diabetes. Most cases are asymptomatic, but it …
