The most common symptom of a UTI in a man is a burning or stinging sensation when urinating. Other telltale signs include a persistent, strong urge to urinate, passing only small amounts of urine despite that urgency, and urine that appears cloudy, dark, or tinged with blood. While UTIs are far more common in women, they do occur in men and tend to require a longer course of treatment when they do.
Common UTI Symptoms in Men
Most UTIs in men start in the urethra or bladder and produce a recognizable set of urinary symptoms:
- Burning during urination: a sharp or stinging pain as urine passes through the urethra
- Urinary urgency: a strong, sudden need to urinate that doesn’t go away, even right after you’ve gone
- Frequent urination: going to the bathroom more often than usual but only passing small amounts each time
- Blood in urine: urine that looks red, bright pink, or cola-colored
- Cloudy or foul-smelling urine
- Pressure or discomfort in the lower abdomen
These symptoms can come on suddenly and range from mildly annoying to genuinely disruptive. If the infection is limited to the urethra, burning during urination is often the main complaint. When the bladder is involved, urgency and frequency become more prominent, and pelvic pressure tends to set in.
Signs the Infection Has Spread to the Kidneys
A bladder infection that goes untreated can travel upward to the kidneys. When that happens, the symptoms shift noticeably. You may develop a fever with chills, pain in your back, side, or groin, nausea, or vomiting. The urine often becomes darker or more foul-smelling than with a simple bladder infection.
A kidney infection is a more serious condition that occasionally leads to dangerous complications if bacteria enter the bloodstream. Warning signs of this include confusion, rapid breathing and heart rate, severe pain, or shortness of breath. These symptoms warrant immediate medical attention.
How UTI Symptoms Overlap With STIs
Burning during urination is one of the most common reasons men visit a doctor, and it doesn’t always point to a UTI. Chlamydia, gonorrhea, and other sexually transmitted infections produce the same painful, burning sensation when you urinate. The key difference is discharge. A UTI typically does not cause fluid dripping from the tip of the penis, while STIs commonly do. If you notice any discharge, especially if it’s yellow, green, or milky, an STI is more likely than a straightforward UTI.
Because the symptoms overlap so closely, testing is the only reliable way to distinguish between the two. A urine sample can identify bacteria associated with a UTI, and separate testing can screen for STIs.
UTI Symptoms vs. Prostatitis
Men have a body part that women don’t in the urinary pathway: the prostate. When the prostate becomes inflamed, a condition called prostatitis, many of the symptoms mirror a UTI. Frequent urination, burning, blood in the urine, and lower abdominal pain all show up in both conditions.
Prostatitis tends to add a few distinctive symptoms on top of those. Pain in the perineum (the area between the scrotum and rectum), painful ejaculation, blood in semen, erectile difficulties, and a urine stream that stops and starts are all more characteristic of prostatitis than a simple UTI. In its chronic form, prostatitis can cause pelvic pain lasting months or even years, affecting roughly 1 in 3 men at some point. A UTI can actually trigger certain types of prostatitis, so the two conditions sometimes coexist.
Why Men Get UTIs Less Often, but Still Do
Men’s longer urethra makes it harder for bacteria to reach the bladder, which is why UTIs are relatively uncommon in younger men. The risk increases with age, largely because of prostate enlargement. As the prostate grows, it can prevent the bladder from emptying completely, and that retained urine becomes a breeding ground for bacteria. Men who experience recurring UTIs often have an underlying factor like prostate enlargement, kidney stones, catheter use, or a structural issue in the urinary tract.
Because of these underlying risks, doctors generally treat UTIs in men more cautiously. A standard antibiotic course for a man lasts about 7 days, compared to 5 days for most women with an uncomplicated infection. Your doctor will likely want a urine culture to confirm which bacteria is responsible and ensure the right antibiotic is prescribed.
What to Expect During Diagnosis
If you go in with symptoms, your doctor will ask for a urine sample. The lab looks for bacteria, white blood cells, and sometimes runs a culture to identify the specific organism. In men, a lower bacterial count in the sample can still indicate a true infection compared to the threshold used for women, so even a result that seems borderline may be clinically meaningful.
For a first-time, straightforward UTI, that urine test is often all that’s needed. If you’ve had recurring infections, your doctor may want imaging of the urinary tract or a closer look at prostate health to identify what’s making you prone to reinfection. Most men start feeling better within a day or two of starting antibiotics, but finishing the full course is important to clear the infection completely and prevent resistance.
