Urine epithelial cells are a type of cell that can be found in the urine. These cells are shed from the lining of the urinary tract and are typically identified through a microscopic examination of a urine sample. The presence of urine epithelial cells in a urine sample can be a sign of a urinary tract infection or other types of conditions that affect the urinary tract.

Introduction of Epithelial Cells:

Epithelial cells are one of the types of cells that can be present in urine. They are shed from the lining of the urinary tract and can be identified through a microscopic examination of a urine sample. The presence of epithelial cells in urine can be a sign of an underlying condition affecting the urinary tract. In this context, the three types of epithelial cells found in urine are squamous, transitional, and renal. The causes, diagnosis, and treatment of epithelial cells in urine depend on the specific type and the underlying condition causing their presence.

Defination of Epithelial Cells in urine:

Epithelial cells in urine refer to the shedding of cells from the lining of the urinary tract that can be found in a urine sample. The presence of epithelial cells in urine can be an indication of various urinary tract conditions, including infections or damage to the urinary tract. Identifying the type and quantity of epithelial cells in urine can aid in diagnosis and treatment of underlying conditions.

Types of Urine Epithelial Cells:

There are three types of epithelial cells that can be found in urine:

Squamous epithelial cells: These are flat, scale-like cells that are typically found in the lining of the urethra and vagina.
Transitional epithelial cells: These are round or oval-shaped cells that are typically found in the lining of the bladder and ureters.
Renal epithelial cells: These are cells that originate from the kidney, and their presence in a urine sample can indicate kidney damage or disease.

Causes of Epithelial Cells in Urine:

The causes of epithelial cells in urine can include:

Urinary tract infections (UTIs): UTIs can cause inflammation and damage to the lining of the urinary tract, leading to the shedding of epithelial cells into the urine.
Bladder or kidney infections: Infections of the bladder or kidneys can cause the shedding of epithelial cells into the urine. The severity of the infection can affect the amount and type of epithelial cells present.
Kidney damage or disease: Damage to the kidneys can cause the shedding of renal epithelial cells into the urine. This can indicate the presence of kidney disease, such as glomerulonephritis.
Contamination of the urine sample during collection: Epithelial cells from the skin, vaginal canal, or penis can contaminate the urine sample during collection, leading to the presence of epithelial cells in the sample.
Trauma or injury: Trauma or injury to the urinary tract, such as from a catheter or surgery, can cause the shedding of epithelial cells into the urine.

Symptoms of Epithelial Cells in Urine:

Epithelial cells in urine typically do not cause any specific symptoms. However, the underlying condition causing the presence of epithelial cells in urine may produce a range of symptoms. Here are some possible symptoms associated with epithelial cells in urine:

Pain or burning sensation during urination: This can be a sign of a urinary tract infection, which may be causing the presence of epithelial cells in the urine.
Increased frequency of urination: Frequent urination, or feeling the need to urinate more often than usual, can also be a sign of a UTI.
Urgency to urinate: Feeling a sudden, urgent need to urinate, even if the bladder is not full, can be a symptom of a UTI or other urinary tract condition.
Lower abdominal pain or discomfort: Pain or discomfort in the lower abdomen can be a sign of a UTI or other urinary tract condition.
Back pain: Pain in the lower back, just below the ribs, can be a sign of a kidney infection or other kidney problem.
Fever or chills: A fever or chills can indicate a urinary tract or kidney infection.
Nausea or vomiting: These symptoms can also be associated with a urinary tract or kidney infection.
Cloudy or foul-smelling urine: The presence of epithelial cells in the urine can sometimes cause it to appear cloudy or have an unusual odor. This can be a sign of a UTI or other urinary tract condition.

Why Get Tested:

The reasons why a person may need to get tested for the presence of epithelial cells in their urine can include:

Diagnosis of urinary tract infections (UTIs): The presence of epithelial cells in urine can indicate the presence of a UTI, so testing may be done to confirm the diagnosis.
Monitoring of UTI treatment: Testing may be done to monitor the effectiveness of treatment for a UTI, and to ensure that the infection has cleared.
Monitoring of kidney function: The presence of renal epithelial cells in urine can indicate kidney damage or disease, so testing may be done to monitor kidney function.
Screening for kidney disease: Testing may be done as part of routine screening for kidney disease, particularly in individuals with risk factors such as diabetes or high blood pressure.
Investigation of blood in the urine (hematuria): Testing may be done to investigate the presence of blood in the urine, which can be a sign of a urinary tract or kidney problem.
Evaluation of bladder or kidney stones: Testing may be done to evaluate the presence of bladder or kidney stones, which can cause urinary tract symptoms.
Monitoring of chronic kidney disease: Testing may be done to monitor the progression of chronic kidney disease and to assess the effectiveness of treatment.
Pre-operative testing: Testing may be done prior to surgery to ensure that the urinary tract is functioning properly and to identify any potential complications.

When to get tested:

here’s a list of situations when a person may need to get tested for the presence of epithelial cells in their urine, along with brief descriptions:

If you have symptoms of a urinary tract infection (UTI): Symptoms of a UTI can include pain or burning during urination, increased frequency of urination, and cloudy or foul-smelling urine.
If you have symptoms of a kidney infection: Symptoms of a kidney infection can include fever, chills, back pain, and nausea or vomiting.
If you have blood in your urine: Blood in the urine can be a sign of a urinary tract or kidney problem, so testing may be done to investigate the cause.
If you have risk factors for kidney disease: Risk factors for kidney disease can include diabetes, high blood pressure, and a family history of kidney disease.
If you have a history of kidney problems: If you have a history of kidney problems, your doctor may recommend regular testing to monitor your kidney function.
If you are taking medication that can affect kidney function: Some medications can affect kidney function, so testing may be done to monitor for any potential problems.
If you are pregnant: Pregnant women may be tested for the presence of epithelial cells in their urine as part of routine prenatal care, as urinary tract infections can be more common during pregnancy.
As part of a routine health check-up: Urinalysis, including testing for epithelial cells, may be done as part of a routine health check-up to screen for any potential problems.

Diagnosis of Epithelial Cells in Urine:

Here’s a list of common diagnostic methods for the presence of epithelial cells in urine:

Urinalysis: This is the most common diagnostic test for the presence of epithelial cells in urine. A small sample of urine is collected and examined under a microscope to determine the number and type of cells present.
Urine culture: If a urinary tract infection is suspected, a urine culture may be done to identify the type of bacteria causing the infection and determine the appropriate treatment.
Imaging tests: Additional imaging tests, such as an ultrasound or CT scan, may be ordered to evaluate the kidneys and urinary tract for any structural abnormalities or blockages.
Blood tests: If a kidney problem is suspected, blood tests may be ordered to assess kidney function.
Cystoscopy: In some cases, a cystoscopy may be performed to examine the bladder and urinary tract for any abnormalities.
Biopsy: In rare cases, a biopsy may be done to examine any abnormal tissue in the urinary tract or kidneys.

It’s important to note that the specific diagnostic methods used will depend on the suspected underlying cause of the epithelial cells in urine. Your healthcare provider will determine the appropriate tests based on your symptoms and medical history.

Required Sample and Preparation:

To diagnose epithelial cells in urine, a urine sample is required. The sample can be collected at any time of the day but it’s best to collect the first morning urine as it is more concentrated and may contain higher levels of certain substances, including epithelial cells.

Here are the general steps for preparing for a urine sample collection:

Wash your hands thoroughly with soap and water.
Clean the genital area with a cleansing wipe or soap and water.
Begin urinating into the toilet.
After a few seconds, collect a sample of urine in a sterile container provided by your healthcare provider or purchased from a pharmacy.
Fill the container at least halfway with urine.
Finish urinating into the toilet.
Securely close the container with the lid provided.

It’s important to avoid contaminating the urine sample with any bacteria from the skin or genital area, so make sure to follow your healthcare provider’s instructions for collecting the sample. Additionally, avoid consuming any foods or beverages that may affect the urine results, such as caffeine, alcohol, and certain medications.

Type of urine samples:

Random sample:
This is a diluted urine sample and may give an inaccurate interpretation of patient health. But is best to do microscopy to evaluate WBC or RBC.
First Morning sample:
This is the best sample for microscopy and urine analysis. This is the concentrated urine because of urine remained throughout the night in the urinary bladder. This will contains an increased concentration of analytes and cellular elements. Urine must have remained in the bladder for 8 hours is considered as the first-morning sample.
Urine for sugar (Postprandial 2 hours):
Postprandial 2 hours sample collected after 2 hours of high carbohydrate diet.
Midstream clean catch urine:
This sample is needed for the culture and sensitivity of urinary infection. The patient is advised to clean the urethra, then discard the first few mL of urine. Now midstream of the urine is collected in the sterile container.
24 Hours of a urine sample
- In this case, discard the first urine and note the time.
- Now collect urine in the container for 24 hours and put the last sample in the container.
- Refrigerate the sample.
- This 24 hours samples are needed for measuring urea, creatinine, sodium, potassium, glucose, and catecholamines.
Suprapubic collection of the urine sample:
This is done in the patients who cannot be catheterized and the sample is needed for culture. This sample is collected by the needle.
Catheter collection of urine:
This is done by patients who are bedridden and can not urinate.
Pediatric urine sample:
In infants, special collection bags are made adherent around the urethra. Then urine is transferred to a container.

Normal Values:

Here are the normal values for epithelial cells in urine, as indicated by a urinalysis:

Squamous epithelial cells: 0-5 per high power field (HPF)
Transitional epithelial cells: 0-5 per HPF
Renal tubular epithelial cells: 0-1 per HPF

It’s important to note that these values may vary slightly depending on the laboratory and testing methods used. Your healthcare provider will interpret the results of your urinalysis in conjunction with your medical history and physical exam to determine if any further testing or treatment is necessary.

Result Interpretation:

Here’s a table that summarizes the interpretation of epithelial cell results in urine:

Epithelial Cell Type	Normal Range	Abnormal Range	Interpretation
Squamous epithelial cells	0-5 per high power field (HPF)	>5 per HPF	May indicate contamination from the genital area or improper collection technique
Transitional epithelial cells	0-5 per HPF	>5 per HPF	May indicate inflammation or infection in the urinary tract, kidney stones, or bladder cancer
Renal tubular epithelial cells	0-1 per HPF	>1 per HPF	May indicate damage to the kidney tubules due to infection, medication toxicity, or other conditions

It’s important to note that the interpretation of epithelial cell results in urine can vary depending on the individual and the underlying cause. Your healthcare provider will interpret the results of your urinalysis in conjunction with your medical history and physical exam to determine if any further testing or treatment is necessary.

Abnormal Results of Urine Epithelial Cells Test:

Abnormal values of urine epithelial cells can be seen in various conditions or diseases. Some examples include:

Urinary tract infection: Bacterial or fungal infections can cause an increase in the number of epithelial cells in urine, particularly transitional cells.
Kidney disease: Damage or injury to the kidneys can cause the shedding of renal tubular epithelial cells into urine.
Bladder cancer: High numbers of transitional epithelial cells in urine could suggest inflammation, infection, or cancer of the urinary tract.
Interstitial cystitis: This condition causes inflammation of the bladder and can lead to an increase in the number of transitional epithelial cells in urine.
Prostatitis: Inflammation of the prostate gland can cause an increase in the number of transitional epithelial cells in urine.
Radiation therapy: Treatment for bladder or prostate cancer that involves radiation therapy can cause an increase in the number of epithelial cells in urine.

It’s important to note that the presence of abnormal values of epithelial cells in urine doesn’t always indicate a problem, as some factors such as contamination of the urine sample can affect test results. A healthcare professional can evaluate test results in the context of other factors, such as symptoms and medical history, to make an accurate diagnosis.
