Seeing yeast in the urine along with white blood cells points to a fungal urinary tract infection, usually candiduria. The white blood cells indicate an inflammatory response from infection, and yeast presence suggests Candida species rather than a bacterial cause. Bacterial UTIs often test positive for nitrites because many bacteria reduce nitrates to nitrites; yeast does not produce that signal, so a nitrite-positive finding would lean toward bacteria rather than a fungal infection. Trichomonas vaginitis is a vaginal infection and isn’t the typical finding in urine with pyuria. Amorphous urates are crystals, not an infection. So, the combination of yeast with white blood cells most strongly supports a Candida infection of the urinary tract, especially in people with risk factors like catheterization or recent antibiotic use.
