Urinary tract infections, or UTIs, are quite rare in adult males younger than 50 years old; however the incidence of UTIs in males over 50 is much more common. Because the male urinary tract has several natural defenses against infection, a UTI in men is considered complicated, according to Medscape.
WebMD explains that symptoms of a UTI include painful, frequent urination and bladder pain. A urinalysis, or culture of the patient's urine, determines if bacteria are causing the infection, the kind of bacteria present, and what antibiotics will best treat the infection. Doctors often order additional tests for men diagnosed with a UTI to determine if factors other than bacteria are causing the infection. These tests include blood tests and x-rays and ultrasounds of the urinary tract, according to WebMD.
