Urine breath: Patients who are uremic and not on dialysis try to excrete their increase blood urea nitrogen through their lungs. That is what causes their breath to smell similar to urine. Have that person see a nephrologist to assess the state his kidney function. His breath is a sign of advanced kidney disease.
