Hey doctors foul smelly urine is a symptom of bladder infection ?

Not a reliable symp.: Some people equate smelly urine an infection- inferred because "the smell must be the result of byproducts of bacterial activity in the urine". However, please remember that a patient must have symptoms of a urinary infection to secure the diagnosis- if the patient is asymptomatic, then the smell is likely because of a dietary byproduct or a a substance that is excreted in the urine.
