Pus in Urine – What Does it Mean?

The production of pus happens during an infection. If there’s pus in your urine, it can be a cause for concern.

If you notice this symptom, you should talk to your doctor since it signifies an underlying infection. In rarer cases, it might be due to cancer, tuberculosis, and prostatitis.

In this article, we’ll talk about each one in more detail. Hopefully, you’ll have a better understanding of what might be causing this scary symptom.

Tuberculosis (TB)


Thanks to modern day vaccinations, tuberculosis (TB) is rare.

However, it’s still a potential cause for having pus cells in your urine.

Tuberculosis is caused by a bacteria called Mycobacterium tuberculosis (can be killed with antibiotics). 

It attacks the lungs, and if left untreated, can lead to a painful death.

Some symptoms associated with this bacterial infection include:

  • Coughing up blood
  • Chronic cough that won’t go away
  • Unintentional weight loss
  • Fever
  • Chills
  • Loss of appetite
  • Fatigue

Most of these symptoms are easily noticeable.

Tuberculosis can also affect the brain, spine, and kidneys. If you think that you have it, visit a hospital immediately. The sooner you begin treatment, the better your chances of success.

Interstitial Cystitis 

This is a noninfectious condition that affects the bladder. It can leader to pressure on the bladder, and in more serious cases, pus in the urine.

It’s more common in women, but can also occur in men. Fortunately, cystitis is treatable through a variety of means.

Your doctor will be able to give you more specific answers.

Kidney Disorders

The kidney is responsible for filtering out waste products from the body.

If it isn’t working properly, then it can release things that you don’t want it to (like protein for example).

If your kidneys aren’t working, then it might also cause pus to leak out into your urine.

Here are two common kidney disorders to watch out for:

  • Renal Papillary Necrosis: The word “necrosis” refers to the death of cells/tissues. So, renal papillary necrosis is basically the death of renal (kidney) tissue. As pus develops during the process, it can enter the bladder and exit the body in urine.
  • Kidney Stones: This is a relatively common condition that affects people all around the world. In addition to pus, it can also cause blood to appear in your urine. If you see this, seek medical help as soon as possible. If left untreated, kidney stones can lead to death.

These are the two most common kidney disorders associated with pus in the urine. Some others include polycystic kidneys, lupus nephritis, and interstitial nephritis.

These are examples of noninfectious conditions that can affect the body.

Urinary Tract Infections (UTI) 

If bacteria are able to accumulate in the urinary tract, then it can lead to a urinary tract infection. It can effectively be treated with antibiotics.

Vaginal discharge (women) and lower abdominal pain are a few of the many symptoms of UTIs.

In serious infections, you could also have pus in the urine.

Some people are more prone to UTIs than others, but that’s typically because of their own wrongdoings. Here’s a great article showing how you can decrease your risk.


Though rare, this is another possibility for your symptom. If pus is exiting your body in urine, it could be the result of the uncontrollable growth of cancer cells.

There are various diagnostic tests that can determine if you have cancer. Talk with your doctor about your symptoms so that they can determine whether or not you have cancer.


Prostatitis is the inflammation and swelling of the prostate glands. As they grow larger, they can crowd on surrounding organs – particularly, the bladder.

This can lead to chronic pain and discomfort. It can also cause pus in the urine to appear.

Other Potential Causes 

While the above causes are the most common, there are a few others. These include:

  • Stress
  • Dehydration
  • Lack of exercise (or too much exercise)
  • Certain drugs

If you’ve had prostate surgery recently then this might also cause pus to leave the body in your urine.

In fact, people who’ve recently had prostate surgery should expect puss cells to appear in their urine for a few months.

Home Remedies 

Before trying any of the remedies we’re about to show, talk to your doctor first. They include:

  • Drink More Water: By drinking more water, you’ll be able to flush out bacteria from your urinary tract (thus, decreasing your chances of a UTI). Staying hydrated also allows your body to continue functioning optimally.
  • Get More Vitamin C: Vitamin C is great for strengthening your immune system. This helps your body fight infections more effectively. Foods like bananas, oranges, and guavas are rich in vitamin C.
  • Eat Yogurt: Believe it or not, yogurt contains a healthy amount of good bacteria. This good bacteria can actually help your body fight the bad bacteria (the bacteria that cause pus in the urine).
  • Eat Garlic: Garlic is associated with dozens of health benefits, including the proper functioning of your immune system. While some people don’t like the taste, it’s very healthy and should be eaten daily.
  • Baking Soda: When you eat baking soda, it decreases the acidity of your urine. This means it less likely for certain bacteria to thrive there. For preventing UTIs, it’s highly recommended.

Obviously, if the pus in your urine is due to a more serious cause, you’ll need to seek medical intervention. If, for example, you’ve been diagnosed with bladder cancer, then you’ll need chemotherapy, surgery, or radiation.

If you have an infection – like a UTI or tuberculosis – then you’ll need antibiotics. For pus caused by STDs, you’ll need specialized medications. Finally, something like kidney stones or prostatits may require surgery.

Are You Drinking Enough Cranberry Juice?

Cranberry juice is an overlooked option for preventing UTIs.

It contains compounds that can inhibit the growth of bacteria in the urinary tract.

Acidic in nature, it makes it difficult for bacteria to survive and divide.

One compound in particular, proanthocyanidin, helps prevent bacteria from sticking to the walls of the urinary tract.

So, whenever you pee, the bacteria will exit your body in your urine.

To potentially decrease pus in the urine, experts recommend drinking about 400 ml of cranberry juice per day.

Pus in Urine – Summary 

To summarize, pus in the urine can be caused by a variety of things, ranging from common to life-threatening.

Most people automatically assume the worst and diagnose themselves with cancer.

However, cancer isn’t the most common cause of this symptom.

It’s more likely that you have something like a urinary tract infection (UTI) or kidney stones, both of which are treatable via medical intervention.
