Epithelial Cells in Urine: Types, Causes, Symptoms and Treatment

Most people think of urine as just waste leaving the body (but there is actually a lot more going on). Did you know that urine has tiny particles called epithelial cells? These little cells can tell us about our body. Depending on how many there are and their type they can point to things like infections (or even kidney problems).

What are Epithelial Cells in Urine?

To understand the significance of epithelial cells in urine, it is essential first to grasp what these cells are. Epithelial cells are specialised cells that line various organs and structures in the body forming a protective barrier. They also line the urinary tract, including the kidneys, ureters, bladder, and urethra. Typically, a small number of epithelial cells may be present in urine, but when their levels become abnormal, it can indicate an underlying health issue.

Types of Epithelial Cells in Urine

Epithelial cells in urine can be of three main types: squamous, transitional, and renal tubular. 

• Squamous epithelial cells are flat, scale-like cells typically present in the urethra. 
• Transitional epithelial cells are larger and rounder and line the urinary bladder and ureters. These are more common in older adults. 
• Renal tubular epithelial cells are cuboidal or columnar in shape and originate from the renal tubules of the kidneys. An increased number of these cells in urine might indicate kidney disorder.

Causes of Epithelial Cells High in Urine

Various factors can cause increased epithelial cells in urine with most common being urinary tract infection (UTI). When bacteria reach the urinary tract they can cause inflammation causing more epithelial cells into the urine. 

Other possible causes of epithelial cells in urine include kidney infections, bladder infections, kidney stones (and even certain kidney diseases). In some cases, high levels of epithelial cells may also result from contamination while collecting a urine sample.

Symptoms of Epithelial Cells in Urine

Epithelial cells in urine may not always cause noticeable symptoms. However underlying conditions contributing to an abnormal number of epithelial cells can manifest with specific symptoms. For example a UTI associated with increased epithelial cells may lead to various symptoms, such as frequent urination, pain or burning sensation during micturition, cloudy or foul smelling urine and pelvic discomfort.

Treatment for Epithelial Cells in Urine

The treatment for epithelial cells high in urine depends on the underlying cause. If a urinary tract infection is detected, your doctor may prescribe antibiotics to remove the infection and reduce the presence of epithelial cells. If kidney stones or other kidney problems are behind it your doctor will probably suggest ways to treat those first.

Conclusion

You might not think much about what’s in your urine, but those tiny epithelial cells can actually tell you a lot about how your body is doing. If you notice changes like more of these cells showing up or other odd symptoms it is a good idea to check in with your doctor. It can feel a bit overwhelming but learning what these cells mean helps you look after your health and catch issues early.

FAQs

1. What does it mean if increased epithelial cells are in urine?

Increased epithelial cells in urine can indicate underlying medical conditions. They are

• Urinary tract infection
• Kidney infection
• Bladder infection
• Kidney disease.

2. Are epithelial cells in urine a cause for concern?

While a small number of epithelial cells in urine is normal an increased or abnormal amount may indicate an underlying problem. Therefore you should consult a doctor if you notice changes in your urine or experience accompanying symptoms.

3. How are epithelial cells in urine treated?

The treatment for epithelial cells in urine depends on the underlying cause. If a urinary tract infection is detected, a doctor may suggest antibiotics. Other conditions (such as kidney stones or kidney diseases) may require specific treatments targeted at those conditions.

4. Can contaminated urine samples affect epithelial cell levels?

Contamination during the collection of a urine sample can affect the levels of epithelial cells.

5. What are the symptoms associated with increased epithelial cells in urine?

Increased epithelial cells in urine may not cause specific symptoms on their own. However underlying conditions that contribute to abnormal epithelial cell levels, such as urinary tract infections can manifest with symptoms such as :

• Frequent urination
• Pain or burning during urination
• Cloudy or foul smelling urine
• Pelvic discomfort.
