Pyuria: Causes, Symptoms, and Treatment

Pyuria is marked by an unusually high concentration of white blood cells or pus found in the urine, often signalling an underlying health issue. The following article will provide an overview of pyuria, including its definition, causes, and prevalence.

What is Pyuria?

Pyuria is a urinary disorder defined by an increased presence of white blood cells or pus in the urine. Pus is a dense fluid made up of white blood cells, dead tissue, and bacteria, formed by the body as a defence mechanism against infections. Pyuria is diagnosed when there are 10 or more white blood cells per cubic millilitre of urine.

Sterile Pyuria:

Sterile pyuria is a subtype of pyuria that occurs when white blood cells are present in the urine, but a doctor cannot detect bacteria.

Causes

Pus develops when the immune system reacts to infections from bacteria or fungi that enter the body through cuts, inhalation, or unsanitary conditions. The immune system dispatches white blood cells known as neutrophils to attack invading microbes, which results in the destruction of both the neutrophils and nearby tissue. This dead material accumulates to form pus. Bacteria like Staphylococcus aureus and Streptococcus pyogenes cause pus formation by releasing toxins that harm tissues and activate the immune system.

Who is at Risk?

Anyone can develop pyuria, but it is more common in women, especially those who are over 45 or experiencing menopause. Pyuria may indicate the presence of various health conditions, but it frequently appears alongside urinary tract infections (UTIs), which are prevalent health issues. Each year, 8 to 10 million people receive treatment from a doctor for a UTI.

Where Does Pus Form?

Pus is typically found in an abscess, which is a space or cavity formed by damaged tissue. Abscesses may form either on the skin’s surface or deep inside the body. Some areas of the body are more susceptible to bacterial infections, including the urinary tract, mouth, skin, and eyes. For instance, urinary tract infections are primarily caused by Escherichia coli, which is commonly found in the colon. Dental abscesses can form near the tooth’s root or gums due to untreated cavities or cracks. Boils, infected hair follicles, and severe acne can lead to skin abscesses. Eye infections such as conjunctivitis, along with blocked tear ducts or the presence of foreign particles, can also cause pus to develop.

Prevalence of Pyuria

Pyuria is a relatively common condition. Nearly 14% of women and people assigned female at birth experience sterile pyuria, while 2.6% of men and people assigned male at birth have this condition. Sterile pyuria can result from a sexually transmitted infection (STI) or other infections.

Symptoms and Odour

If pyuria is a symptom of a urinary tract infection, your urine may emit a strong, ammonia-like odour. Ammonia has a strong, distinct smell that can irritate the nasal mucous membranes. It is a common ingredient in several cleaning products.

Diagnosis and Treatment

To diagnose pyuria, a doctor can perform a urinalysis by testing your urine sample for white blood cells, bacteria, and blood. The treatment for pyuria depends on the underlying cause. UTIs, bacterial STIs, or tuberculosis are typically treated with antibiotics, which should be completed in full even if the symptoms subside. If pyuria persists after completing antibiotics, it is important to consult a doctor to determine if another condition is the cause.

Leaving pyuria untreated can result in serious complications, such as septicemia, kidney damage, organ failure, and even death. Although some believe that cranberry juice can prevent or treat UTIs that cause pyuria, more research is needed to confirm its effectiveness. Therefore, individuals with pyuria should discuss appropriate treatment options with their doctor.

What Questions Should I Ask a Doctor?

If you have been diagnosed with pyuria, you may want to ask your doctor some important questions, such as

• How did they arrive at the diagnosis?
• What other conditions could be causing your symptoms?
• How did you contract the infection?
• What treatments do they recommend?
• It is also important to ask about the dosage and schedule for medication, and proper storage of the medication.
• When to expect improvement, and whether a follow-up appointment is necessary?

Who should you consult with for pus in the urine?

You may want to ask if you should see a specialist, such as a urologist or a nephrologist, for further evaluation and treatment.

Can Pus be Prevented?

Although some infections are inevitable, you can lower your risk by taking the following steps: keeping cuts and wounds clean and dry, refraining from sharing razors, and avoiding picking at pimples or scabs. If you already have an abscess, there are ways to prevent the infection from spreading, such as not sharing towels or bedding, washing your hands after touching the abscess, and avoiding communal swimming pools and shared gym equipment that may come in contact with the abscess.

Conclusion

Pyuria is a condition in which an unusually high number of white blood cells or pus is found in the urine. It can indicate the presence of several health conditions, and it often appears alongside UTIs. Anyone can develop pyuria, but it is more common in women, especially those who are over 45 or experiencing menopause. If you are experiencing symptoms of pyuria, it is essential to seek medical advice promptly.
