Quick Summary: Finding atypical urothelial cells in your urine doesn’t always mean you have cancer. Infections, inflammation, kidney stones, or even just using a catheter can cause these cells to show up. Your doctor will likely order more tests, like a repeat urine test or a cystoscopy, to figure out the exact cause and the best way to treat it.
Ever get a strange result from a urine test? Finding “atypical urothelial cells” can be a bit scary. But don’t panic! It doesn’t automatically mean something serious. Lots of things can make these cells show up in your pee. Think of it like this: your body is talking to you, and these cells are just part of the conversation.
This guide will walk you through the most common reasons why these cells might be present. We’ll break it down step-by-step, so you understand what’s happening and what your doctor might do next. Ready to learn more about those little cells? Let’s dive in!
Understanding Urothelial Cells
First things first, let’s talk about what urothelial cells actually are. These cells line your urinary tract, which includes your bladder, ureters (tubes connecting the kidneys to the bladder), urethra (tube carrying urine out of your body), and parts of your kidneys. They’re like the wallpaper of your urinary system. Normally, these cells look pretty uniform and organized under a microscope. But sometimes, they can appear “atypical,” meaning they look a bit different from the norm.
What Makes Urothelial Cells “Atypical”?
Atypical urothelial cells aren’t necessarily cancerous. “Atypical” just means they have some unusual features. These features might include:
- Larger size than normal
- Irregular shape
- Changes in the nucleus (the cell’s control center)
- Increased amount of DNA
These changes can be caused by a variety of factors, which we’ll explore in detail below.
Common Causes of Atypical Urothelial Cells
Now, let’s get to the heart of the matter: what can cause these atypical cells to show up in your urine? Here are some of the most common culprits:
1. Urinary Tract Infections (UTIs)
UTIs are a very common cause. When bacteria infect your urinary tract, they can irritate and inflame the urothelial cells. This inflammation can cause the cells to change their appearance, leading to atypical results.
Symptoms of a UTI:
- Frequent urination
- Pain or burning during urination
- Cloudy or bloody urine
- Strong-smelling urine
- Pelvic pain (in women)
If you have these symptoms along with atypical urothelial cells, your doctor will likely test you for a UTI and prescribe antibiotics if needed. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) offers additional information on UTIs.
2. Inflammation
Inflammation from other conditions besides infection can also affect urothelial cells. This can include:
- Bladder inflammation (cystitis): This can be caused by irritants, medications, or autoimmune conditions.
- Kidney inflammation (nephritis): This can be caused by infections, medications, or autoimmune diseases.
Inflammation can irritate the lining of your urinary tract, causing urothelial cells to become atypical.
3. Kidney Stones
Kidney stones are hard deposits that form in your kidneys. As they move through your urinary tract, they can cause irritation and damage to the urothelial cells. This irritation can lead to the appearance of atypical cells in your urine. The Mayo Clinic has comprehensive resources on kidney stones.
Symptoms of Kidney Stones:
- Severe pain in your side and back, below the ribs
- Pain that radiates to the lower abdomen and groin
- Pain that comes in waves and fluctuates in intensity
- Painful urination
- Pink, red or brown urine
- Cloudy or foul-smelling urine
- Nausea and vomiting
- Frequent urination
- Fever and chills if an infection is present
4. Catheter Use
If you’ve recently had a urinary catheter, this could be the reason for atypical cells. The catheter can irritate the lining of your urethra and bladder, causing inflammation and changes in the urothelial cells. This is usually temporary and resolves after the catheter is removed.
5. Benign (Non-Cancerous) Conditions
Sometimes, atypical urothelial cells can be caused by benign conditions such as:
- Reactive changes: These are changes in the cells in response to irritation or injury.
- Metaplasia: This is a change in the type of cell lining the urinary tract.
These conditions are not cancerous and usually don’t require treatment.
6. Exposure to Certain Chemicals or Medications
Certain chemicals and medications can irritate the bladder and urinary tract, leading to atypical cells. This includes:
- Cyclophosphamide: A chemotherapy drug
- Certain dyes: Used in some medical procedures
- Occupational exposures: Working with certain chemicals in industries like rubber, leather, and textiles
7. Urothelial Cancer
While atypical urothelial cells are often caused by benign conditions, they can sometimes be a sign of urothelial cancer, also known as bladder cancer. This is why it’s important to follow up with your doctor for further evaluation.
Risk factors for urothelial cancer include:
- Smoking
- Age (over 55)
- Exposure to certain chemicals
- Chronic bladder infections
- Family history of bladder cancer
Next Steps: What Happens After Atypical Cells Are Found?
If your urine test shows atypical urothelial cells, your doctor will likely recommend further testing to determine the cause. Here’s what you can expect:
1. Repeat Urine Test
Often, the first step is to repeat the urine test to see if the atypical cells are still present. Sometimes, the initial result can be a false positive due to contamination or other factors.
2. Urine Culture
A urine culture checks for bacteria in your urine. This can help determine if you have a UTI.
3. Cystoscopy
A cystoscopy is a procedure where a thin, flexible tube with a camera (cystoscope) is inserted into your urethra and bladder. This allows your doctor to directly visualize the lining of your urinary tract and look for any abnormalities, such as tumors or inflammation. The National Cancer Institute provides detailed information on cystoscopy.
4. Biopsy
If your doctor sees anything suspicious during the cystoscopy, they may take a biopsy. A biopsy involves removing a small tissue sample for examination under a microscope. This is the only way to definitively diagnose urothelial cancer.
5. Imaging Tests
In some cases, your doctor may order imaging tests such as:
- CT scan: This uses X-rays to create detailed images of your urinary tract.
- MRI: This uses magnetic fields and radio waves to create images of your urinary tract.
- Ultrasound: This uses sound waves to create images of your urinary tract.
These tests can help identify tumors, kidney stones, or other abnormalities.
Treatment Options
The treatment for atypical urothelial cells depends on the underlying cause. Here’s a quick overview of common treatment approaches:
| Cause | Treatment |
|---|---|
| UTI | Antibiotics |
| Kidney Stones | Pain medication, increased fluid intake, medications to dissolve stones, or surgery |
| Inflammation | Medications to reduce inflammation, such as corticosteroids |
| Urothelial Cancer | Surgery, chemotherapy, radiation therapy, immunotherapy |
Preventing Atypical Urothelial Cells
While you can’t always prevent atypical urothelial cells, here are some things you can do to keep your urinary tract healthy:
- Drink plenty of fluids: This helps flush out bacteria and other irritants from your urinary tract.
- Practice good hygiene: Wipe from front to back after using the toilet to prevent bacteria from entering your urethra.
- Urinate after intercourse: This helps flush out any bacteria that may have entered your urethra.
- Avoid smoking: Smoking is a major risk factor for bladder cancer.
- Limit exposure to certain chemicals: If you work with chemicals, follow safety precautions and wear protective gear.
When to See a Doctor
It’s important to see a doctor if you experience any of the following symptoms:
- Blood in your urine
- Frequent or painful urination
- Pelvic pain
- Back pain
- Unexplained weight loss
These symptoms could indicate a serious underlying condition that needs to be treated.
