What Happens If Urinary Retention Goes Untreated?

Going to the toilet should leave you feeling like your bladder is empty. But what if it doesn’t?

You may finish urinating and still feel like there is more left. Maybe the flow is slower than usual. You might even find yourself back in the bathroom again after a short while. This can happen with urinary retention.

In simple terms, the bladder holds on to urine instead of emptyingem like a small inconvenience at first. If it keeps happening, though, it can cause problems that go beyond frequent bathroom trips.

For men, an enlarged prostate is a common one. It can press on the urethra and make it harder for urine to pass. Stones, constipation, infections and scar tissue may also get in the way.

Sometimes there is no physical blockage. The bladder muscles may be too weak to push all the urine out. Certain nerve problems and medicines can affect bladder emptying as well.

A UTI May Keep Coming Back

Urine sitting in the bladder gives bacteria more time to grow. That can make urinary tract infections more likely.

A UTI may cause burning when you pee. You may feel like you need the toilet again and again, even when very little urine comes out. Some people also notice cloudy urine or discomfort low down in the abdomen.

And there is another concern. If an infection moves further up the urinary tract, it can reach the kidneys.

Your Bladder Can Get Stretched

The bladder is meant to stretch as it fills. Once you urinate, it shrinks again.

With ongoing urinary retention, that normal pattern changes. Too much urine may stay inside for too long. The bladder can become overstretched, and its muscles may gradually lose some of their strength.

Then emptying the bladder becomes even harder.

It can turn into a frustrating cycle: urine stays behind, the bladder becomes weaker, and even more urine may remain the next time.

You Could Leak Urine Too

Urinary retention does not always mean “no urine.” In fact, an overly full bladder can start leaking small amounts.

You may notice dribbling in your underwear or urine escaping without much warning. This is known as overflow incontinence.

So, leaking urine does not always mean the bladder is emptying too easily. Sometimes, it is actually too full.

Bladder Stones Can Become a Problem

Urine left sitting in the bladder can cause another issue: bladder stones. They form when minerals in the urine start collecting and hardening.

You might not feel anything when the stones are small. As they grow, though, things can change. Peeing may become uncomfortable, the urine flow may stop and start, or you might notice blood in your urine. For some people, frequent urine infections are the first sign that something is wrong.

What About the Kidneys?

This is where untreated urinary retention can become more serious.

If the bladder remains very full, pressure can build within the urinary system. In some cases, urine can back up towards the kidneys.

Over time, that pressure may harm kidney function. This does not happen to everyone with urinary retention, but it is one reason persistent symptoms should not simply be ignored.

When Is It Time to See a Doctor?

If your urine stream has become weak, you keep straining to pee, or your bladder never seems completely empty, speak with a healthcare professional. Frequent dribbling or repeated urinary infections also deserve attention.

If you suddenly cannot urinate at all, especially when your lower abdomen feels painful or swollen, seek urgent medical care.

If you are dealing with urinary retention, a weak urine stream or other ongoing urinary symptoms, you can speak with a urologist at Magnet Health in the Bronx.

Don’t Keep Waiting for It to Settle on Its Own

A small change in urination can be easy to brush aside. Maybe you think you are just getting older or drinking too much water.

Untreated urinary retention can lead to infections, leaking, bladder stones and bladder damage. In more serious cases, the kidneys can also be affected. If something about your usual urination has changed and stays that way, getting it checked sooner is the safer choice.
