17 Signs That You Might Have Kidney Stones

11. Smelly Urine

We are probably all familiar with the smell of urine. It normally doesn’t have such a pungent odor. When your urine starts to smell foul, it is often thought to be a sign of a urinary tract infection. But it may also be caused by an infection in your kidneys. This kidney infection may be a result of kidney stones. Kidney stones may also affect the smell of your urine due to ammonia, or the higher presence of salts in the urine. However, this is not a common symptom of kidney stones. More often, it is the appearance of the urine that is affected.
