Bladder Not Emptying Fully? Causes, Symptoms & Treatment

Have you ever finished peeing and sat down only to feel the urge to go back to the bathroom? That could be your bladder not emptying completely.

Incomplete bladder emptying could be frustrating, especially when it affects your day-to-day life. But, it's worth paying attention to since it could be a sign of urinary retention; a common and manageable condition.¹

Let's explore what it is, its signs, causes, and how you could help yourself or your loved one through it.

What Is Urinary Retention?

Urinary retention means your bladder doesn't fully empty when you pee.¹ This means more urine is left behind after you pee (what doctors call post-void residual), creating that incomplete bladder emptying sensation.¹

It could affect both men and women, but it tends to show up more in men.¹ If you're experiencing it, there's no reason to feel embarrassed. Bring it up with your doctor, and you can find a solution together.

Signs Your Bladder Isn't Emptying Fully

If you have difficulty emptying your bladder, you might have noticed the following symptoms:

• A weak or slow urine stream¹
• Trouble starting to pee¹
• Feeling of fullness after urinating¹
• Frequent trips to the bathroom or urgent urges to pee¹
• Leaking after peeing²
• Waking up at night to pee²
• Unexpected leaks, AKA overflow incontinence¹

If any of these symptoms sound familiar, go to the doctor. It could be urinary retention or another bladder emptying problem.^1,2

Your doctor is the best person to tell you the difference.^1,2Also, if you notice you can't pee at all, find medical assistance right away.^1,2 Sudden urinary retention is a medical emergency.^1,2

What Causes Incomplete Bladder Emptying?

A few different things may get in the way of your bladder fully emptying:

• Blockages: Something physically blocks the flow, like an enlarged prostate (common in men), a prolapsed bladder or rectum (more common in women), narrowing of the urethra, bladder stones, or even constipation pressing on the bladder.^1,3
• Nerve problems: Your brain and bladder constantly send signals back and forth to control when you pee.1 Certain health conditions may interrupt that communication.¹
• Medications: Some common types of medication could affect how well your bladder muscle contracts to release urine.¹
• Surgery: Anesthesia, or surgery near the pelvis or spine, could affect bladder function, sometimes for a short while, sometimes longer.¹

How Is Urinary Retention Diagnosed?

Getting a diagnosis when your bladder doesn’t drain isn't complicated. It starts with your doctor asking about your symptoms and medical history, followed by a physical exam. They may test a urine sample to check if an infection is causing your symptoms.¹

They'll likely also run a post-void residual test.¹ This is a non-invasive, painless ultrasound scan of your bladder after you pee.¹ It shows how much pee, if any, is left behind in your bladder.¹

Diagnosis is the first step toward feeling better. It is best to talk to your doctor if you're concerned.

Treatment Options for Urinary Retention

Your doctor might recommend several options when you can't pee fully, depending on the type and cause of your urinary retention.¹

Here are a few they might recommend:

• Catheterization: Draining the bladder with a catheter, either short-term in the hospital or as self-catheterization at home. A nurse or doctor could teach you how.¹
• Medications: Depending on the cause, this might mean taking medications to relax muscles around the prostate, or to treat an underlying infection.^1,4
• Lifestyle and pelvic floor therapy: This may include double voiding, bladder training habits, or working with a pelvic floor specialist to strengthen your pelvic floor muscles.^4,5

If you notice any changes, we recommend talking to your doctor about what is right for you.

Day-to-Day Life with Incomplete Bladder Emptying

Going about your day when you can't empty your bladder takes some planning, but it gets easier. Before heading out, it helps to know where the bathrooms are along your route.

Urges may feel unpredictable and even stressful, but double voiding could help. Pee, wait a moment, then try again to fully empty your bladder.⁴

If bladder leaks are happening, using an incontinence product like TENA's protective underwear for men and women could help keep your skin protected, dry, and comfortable.

These discreet, underwear-like products give you peace of mind whether you're at home or on the go. Meanwhile, your doctor could help you get to the root of the issue.

Supporting Someone with Urinary Retention

Watching someone you care about dealing with bladder issues could leave you feeling helpless, especially since it's a private condition.

But you could do a lot for them, starting with the practical side of things:

• Offer to come to appointments with them, if welcomed.
• Look into treatment options together.
• Assist with home care routines like catheter use.
• Make sure the bathroom at home feels comfortable and private.
• Stock up on absorbent products that are discreet and absorbent, like TENA incontinence products.

Emotionally, the most valuable thing you can do is talking about it gently, without judgment. Urinary retention is a common, manageable condition, not something to feel embarrassed or ashamed about.

When Should You See a Doctor?

If you suddenly can't pee at all, especially with pain or pressure in your lower belly or back, and a fever, go to the emergency room ASAP.¹ It might be acute urinary retention, and it's a medical emergency.^1,2

If symptoms build up gradually, alongside urinary changes, or things are getting worse over time, speak with your doctor soon.^1,2

If something feels off with your bladder overall, talking to a doctor is always the right call.

Urinary Retention Is Manageable

Incomplete bladder emptying could feel frustrating and, at times, isolating, but it's common, and it's manageable.¹

Whether it's a weak stream, that nagging feeling of fullness, or waking up at night more than you'd like, these signs are worth paying attention to.^1,2

A proper diagnosis from your doctor is a start to getting the help you deserve. From there, options range from lifestyle changes to medication to simple techniques like double voiding.^4,5

And if you're supporting someone through it, your patience and understanding matter more than you know.

Whatever's going on with your bladder, you don't have to figure it out on your own. While you talk to your doctor, TENA is here to help you feel comfortable and confident along the way.

FAQs

What Is the Difference Between Urinary Retention and Overactive Bladder?

Overactive bladder happens when your bladder muscle contracts too often, causing that sudden, urgent need to pee.⁶

Urinary retention is nearly the opposite: your bladder muscle doesn't contract strongly enough to fully drain.¹

Both could lead to frequent bathroom trips, which is why people sometimes mix them up.^1,6

If you’re unsure, you should see your doctor. They could run a simple bladder scan to help diagnose the correct condition.¹

Can You Still Pee If You Have Urinary Retention?

Yes, in most cases. Many people with urinary retention may still pee, but their bladder never quite empties all the way; some pee is always left behind.¹

It's only in sudden, severe cases that you might not be able to pee at all.¹

The slower, more gradual kind usually comes from a blockage or when your bladder muscles aren't contracting as well as they should.¹

What Are the Most Common Warning Signs of Incomplete Bladder Emptying?

Common signs could include a weak or slow pee stream, trouble starting to pee, a feeling of fullness even after you've gone, or frequent, urgent urges to pee.¹

You might also notice dribbling after you finish, getting up at night to use the bathroom, or unexpected leaks.^1,2

What Medications Can Cause Urinary Retention?

Some medications could affect how well your bladder muscle works and cause problems emptying it completely when peeing.¹

If you notice changes in bladder function after starting a new medication, mention it to your doctor; they may be able to adjust your prescription.

Is Urinary Retention A Sign of Something Serious?

Chronic urinary retention is often manageable rather than something immediately life-threatening.¹

But you still need to see your doctor to avoid other issues. If you notice you suddenly can’t pee, head to the emergency room right away.^1,2

What Can Happen If Urinary Retention Goes Untreated?

Over time, untreated urinary retention could lead to urinary tract infections, bladder muscle injury, and in more serious cases, added pressure on your kidneys.¹

That’s why we recommend speaking to your doctor once you notice any symptoms.

How Is Incomplete Bladder Emptying Diagnosed?

One of the most common tests is a post-void residual scan, a painless ultrasound that measures how much urine is left in the bladder after peeing.¹

Your doctor may also look at your symptoms and medical history and test a urine sample for signs of infection.¹ From there, they could confirm your diagnosis and give you next steps.¹

Can Women Get Urinary Retention?

Yes, though it is less common in women than in men.3 In women, urinary retention could show up with a prolapsed bladder or uterus, urethral narrowing, bladder muscle dysfunction, constipation, or as a side effect of pelvic surgery or childbirth.³

Many women may not notice the symptoms earlier because they tend to be more gradual and subtle than in men.³

What Can I Do to Help My Bladder Empty More Fully?

A technique called double voiding could help.⁴ After you finish peeing, stand up, move around for a bit, then sit back down and try again.⁴ Leaning forward slightly while you're seated might also help move things along.⁴

These little habits are worth trying while you work with your doctor on an approach that works for you.
