Men who experience more yellow urine and cloudy urine with a greater odor may be experiencing a urinary tract infection. For example, cystitis can present with yellow, cloudy, and smelly urine. Patients should be promptly examined, and routine urine tests can be performed to find more white blood cells in the urine. Urinary ultrasonography should also be performed to clarify whether the patient has risk factors, such as urinary stones, which can easily lead to urinary tract infections after forming an obstruction. There are also some lower urinary tract obstructive diseases that also tend to form urinary tract infections, such as prostatic hyperplasia, urethral stricture, neurogenic bladder, and other diseases that can cause urinary tract infections.
