8 Causes of pus cells in urine – Urinary tract infections

Urinary tract infections (UTIs) are common infections that affect the kidneys, bladder, and urethra. UTIs often cause pain when you urinate and foul-smelling urine. However, if you notice blood in your urine or pus cells in your urine after an infection, it’s important to contact your doctor immediately because it could be the sign of something much more serious like kidney disease or bladder cancer. In this article, we examine what causes pus cells in urine and how to prevent them from coming back.

1. Urinary tract infection

UTIs are one of many possible causes of pus cells in urine. A UTI is an infection of any part of your urinary tract—the organs through which your body disposes of its waste and recycles water, including your bladder, urethra, and kidneys. Infections often start with bacteria from faeces that move up into other parts of your urinary tract. But it can also be caused by E. coli or Klebsiella bacteria, both common types of bacteria found in your intestines. Women have a higher risk for UTIs than men do because women’s shorter urethras make them more vulnerable to infections.

2. Benign Prostatic Hyperplasia (BPH)

One cause of pus cells in urine is a condition called benign prostatic hyperplasia (BPH). When BPH becomes too severe, it can cause acute urinary retention. It also increases your risk of kidney stones and bladder cancer. Luckily, there are several simple steps you can take to control BPH and prevent it from affecting your quality of life. Consult with your doctor for more information.

3. Prostatitis

Painful inflammation of prostate glands is referred to as prostatitis. Commonly, bacteria called Proteus Mirabilis cause prostatitis. As it affects more than 50% of men between 40 and 70 years old, it should be kept in mind. Urinary tract infection is also a common symptom and is caused by E-coli. Therefore, the first step in the prevention of Pus Cells in the Urine should be taking utmost care about bathroom hygiene.

4. Inflammation of the Bladder

A bladder infection (cystitis) can cause pus cells to appear in your urine. Bacteria and/or fungi that infect your urinary tract may be carried out by urination, thus you may notice a cloudy or bloody discolouration of your urine after going to pee. Urinary tract infections usually clear up on their own with rest, some water and over-the-counter medications, but if cystitis keeps coming back then you should see a doctor for an antibiotic prescription.

5. Parasites

Most urinary tract infections (UTIs) are caused by bacteria, but some can be caused by parasites. The most common parasite that causes UTIs is a tiny worm called schistosoma haematobium, which is found in Africa and parts of Asia. If you’re infected with S. haematobium and you don’t treat it, you could develop bladder cancer or kidney disease over time. If you have a UTI and think it might be caused by a parasite, your doctor will test your urine for eggs to confirm his suspicion—and treat you accordingly.

6. Chronic Cystitis

Many people mistake a urinary tract infection (UTI) for a bladder infection. However, there is no such thing as a bladder infection. A UTI is actually an infection of your urethra and/or your bladder. The symptoms for each of these types of infections are very similar but if you have them more than twice a year, you may be diagnosed with cystitis or interstitial cystitis (IC). Both IC and chronic cystitis can cause pus cells to appear in your urine.

7. Kidney Stones (Urolithiasis)

Kidney stones, or urolithiasis, occur when substances such as calcium, phosphorous and other minerals combine together and form a small rock-like material. Most kidney stones pass out through urination without any problem. However, if they cause irritation to your kidneys or urinary tract, there could be blood and pus cells within your urine.

Dead Kidney Tissue (Renal Medullary Carcinoma, RCC)

A type of kidney cancer, renal medullary carcinoma is primarily characterized by cells with high nuclear to cytoplasmic ratios and often contains large amounts of abnormal glycogen. While renal medullary carcinoma can be relatively benign, it is typically more aggressive than other types of kidney cancer. This form of cancer may also contain papillary elements, which increases its aggressiveness.
