Can a UTI go undetected in a urinalysis in a man if the bacteria is in the urethra?

In brief: Possibly, yes

With usual midstream urine specimen, infection only in the urethra might night not show elevated white blood cells or bacteria on urinalysis; the initial flow could flush the urethra.
However, UTI is rarely limited to the urethra. By far the main causes of localized urethral infections are STDs: gonorrhea, chlamydia, or nongonoccal urethritis (NGU). Discuss with doctor, esp if at risk for STD.
