Yes, in the UK, men almost always require extra tests when they present with UTI symptoms. While urinary tract infections are common and often straightforward in women, they are rare in men due to their longer urethra and the antibacterial properties of prostatic fluid. Consequently, a male UTI is clinically classified as a ‘complicated’ infection, and GPs must investigate to ensure there isn’t an underlying structural issue, such as an enlarged prostate or a kidney stone, causing the problem.

Why Men are Different
The primary reason men need extra testing is anatomy. In women, the short distance between the outside world and the bladder makes accidental infection common. In men, the 18-20cm length of the urethra provides a significant physical barrier. If bacteria manage to bypass this barrier, it usually suggests that the urinary “flow” is being obstructed or that the body’s natural defences are compromised.
Because of this, UK clinical guidelines (NICE) state that a simple dipstick test is not enough for a man. Doctors need to know exactly which bacteria are present and if there is a secondary issue like the prostate involved in the infection.
- Anatomical Barrier: The long urethra makes simple infections rare.
- Prostatic Fluid: This fluid contains zinc and other elements that naturally kill bacteria.
- Flow Issues: Most male UTIs are caused by urine “sitting” in the bladder too long.
The Mandatory Urine Culture
While a healthy woman might be diagnosed based on symptoms alone, every man with suspected cystitis must provide a urine sample to be sent to a hospital laboratory for a culture and sensitivity test.
This test identifies the exact species of bacteria and, crucially, which antibiotics are strong enough to kill it. Since men often require a longer course of antibiotics (typically 7 days compared to 3 days for women), ensuring the correct medication is chosen from day one is essential for preventing the infection from spreading to the kidneys or the prostate.
The Prostate and Digital Rectal Examination (DRE)
One of the “extra” tests a man may undergo is a physical examination of the prostate gland. The prostate sits just below the bladder and surrounds the urethra. If it becomes enlarged (Benign Prostatic Hyperplasia) or infected (Prostatitis), it can squeeze the urethra, preventing the bladder from emptying.
A GP may perform a Digital Rectal Examination (DRE) to check the size, shape, and consistency of the prostate. If the prostate feels “boggy” or very tender, it may indicate that the UTI is part of a prostate infection, which requires a much longer course of antibiotics (often 4 to 6 weeks).
Imaging and Specialist Referrals
If a man has recurrent UTIs, blood in his urine, or symptoms that do not clear with antibiotics, he will likely be referred to a urologist for imaging tests. These tests look for structural abnormalities that a physical exam might miss.
- Ultrasound Scan: Uses sound waves to check if the bladder is emptying fully and to look for kidney stones.
- Cystoscopy: A tiny camera is inserted into the urethra to look for narrowings (strictures) or bladder issues.
- Flow Rate Test: Measures the speed and volume of the urinary stream to check for obstructions.
Comparison Table: Standard vs. Extra Tests for Men
| Test Type | Used for Women? | Used for Men? | Reason for Men |
| Urine Dipstick | Yes (Often enough) | Yes (Initial screen) | Quick check for white cells |
| Lab Urine Culture | Sometimes | Always | To identify specific bacteria |
| Prostate Exam (DRE) | No | Commonly | To check for obstruction/infection |
| PSA Blood Test | No | Sometimes | To screen for prostate inflammation |
| Urinary Ultrasound | Rarely | If recurrent | To check for stones or retention |
Summary
Men require extra tests for UTI symptoms because their infections are statistically rare and often linked to underlying urological issues. From mandatory laboratory cultures to prostate examinations and potential ultrasound scans, these extra steps ensure that the root cause of the infection is identified. In the UK, this thorough approach is vital for protecting male kidney health and preventing chronic conditions like prostatitis.
If you experience severe, sudden, or worsening symptoms, such as high fever, uncontrollable vomiting, or intense pain in your side or back, call 999 immediately.
Is it normal for a man to get a UTI?
It is not considered ‘normal’ in the same way it is for women. It almost always warrants a medical investigation to find an underlying cause.
Why can’t a pharmacist treat a man’s UTI?
In the UK, the ‘Pharmacy First’ scheme for UTIs is only for women. Men must see a GP because of the need for extra tests and longer antibiotic courses.
What is a PSA test and do I need one for a UTI?
A PSA test measures a protein produced by the prostate. It can be high during a UTI, so doctors often wait until the infection is cleared before testing it for prostate health.
Can kidney stones cause UTI symptoms in men?
Yes, stones can irritate the urinary tract and trap bacteria, leading to repeat infections that won’t clear until the stone is managed.
How long does a prostate exam take?
A DRE is a very quick procedure, usually lasting less than a minute, but it provides vital information about the health of the urinary tract.
