Symptoms

Not everyone with a UTI will develop symptoms, but most people have some. They can include:

A strong persistent urge to urinate 
A burning sensation when urinating 
Passing frequent, small amounts of urine
Pain in the lower part of your abdomen or lower back
Blood in the urine (hematuria) or cloudy, strong-smelling urine

A man with a urinary tract infection may have a discharge from his penis. A kidney
infection is more serious. Its symptoms include a burning sensation when you urinate,
abdominal and lower back pain, fever, chills, nausea, the frequent need to urinate, and cloudy
 or bloody urine. Some sexually transmitted diseases can cause symptoms that look like a UTI. For example, the
 chlamydia organism can cause urethritis. For this reason, it is important to see a doctor for
 diagnosis if you have any symptoms of a urinary tract infection.
 Symptoms will also get worse if not treated. Untreated UTIs can spread to
 the blood and cause a serious infection that can be fatal.

There are more specific signs and symptoms for each type of UTI. In addition to the symptoms listed above you may experience the following:

Acute pyelonephritis may cause flank pain, high fever, shaking chills and nausea or vomiting. 
Cystitis may result in pressure in the lower abdomen and strong-smelling urine. 
Urethritis may lead to pus in the urine. In men, urethritis may cause penile discharge.
