Bladder irrigation and washout after a TURBT | CION Cancer Clinics
Bladder irrigation is a steady flow of sterile salt water run into the bladder through a catheter and straight back out. It washes blood away before it clots, so the catheter keeps draining while the scraped area heals. For most people it runs for hours and stops once the urine turns pale. This page explains the equipment, what the colour of the bag means, what a washout is, and when to call for help. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What is bladder irrigation after a TURBT, and why is it done?
Bladder irrigation is a slow, steady flow of sterile salt water that runs into the bladder through the catheter and straight back out again. It washes away blood before it can set into clots, so urine keeps draining while the scraped area starts to heal.
Why the bladder needs washing at all
A TURBT removes the tumour by scraping it from the inside lining of the bladder. That leaves a raw patch, rather like a graze, and a raw patch oozes. Blood mixed with urine is fine. Blood that sits still in the bladder can clot, and a clot can block the catheter. A blocked catheter means urine builds up, the bladder stretches and the pain is sharp. Irrigation keeps things moving so that does not happen.
Not everyone has it
If only a small area was scraped and the urine is already running light pink in the recovery room, many surgeons do not start irrigation at all. A plain catheter is enough. It is used more often after a large resection, when several tumours were removed, or when the person takes blood thinners for the heart. Whether you have it is decided at the end of the operation, by what the surgeon saw.
Irrigation and a hand washout are different things. Both are explained further down this page.

Tell the nurse at once if this happens
If the drainage bag stops filling while fluid is still running in, or your lower belly feels tight, swollen and increasingly painful, the catheter may be blocked by a clot. Press the call bell straight away. Do not wait for the next round and do not pull at the tube. If you have already gone home with a catheter and urine stops draining, go to the nearest emergency department the same day.

Ask an oncologistAround the bed
What are all the tubes and bags for?
Families are often alarmed by how much equipment there is. Each piece has one simple job.
The three-way catheter
A soft tube passed through the urethra, the natural passage urine leaves by, into the bladder. It has three channels: one brings fluid in, one lets fluid and urine out, and one fills a small balloon that holds the catheter in place.
The bags of fluid on the stand
Large bags of sterile salt water hang above the bed. They are not a drip into a vein and nothing from them enters your blood. The nurses change them as they empty, which can be often in the first hours.
The drainage bag
This collects everything coming back out. Its colour is how the team judges bleeding.
What the nurses look for
- Red, like fruit juice: flow is turned up
- Pink or rose: flow stays steady
- Clear or pale straw: flow is slowed, then stopped
The roller clamp
A small wheel on the tubing sets the speed. Only the nurse adjusts it. Faster is not always better, because a very fast flow can make the bladder spasm.
Hour by hour
What happens from theatre until the catheter comes out?
Started in theatre
The catheter goes in at the end of the TURBT while you are still under anaesthetic, and irrigation is connected before you wake. You will feel the catheter as a need to pass urine, even though the bladder is empty.
The ward and the first night
Nurses check the colour and measure fluid in against fluid out. Drinking water is usually encouraged once you are awake, because your own urine helps with the washing.
Slowing down
As the bag turns pale, the flow is reduced. If it stays pale with the fluid slowed or paused, irrigation is stopped. For most people this is by the next morning.
The catheter comes out
Once urine stays light without irrigation, the balloon is emptied and the catheter slides out. You are asked to pass urine before going home, and the amount may be checked with a quick bladder scan.

Being straight with you
How long does it last, and what is a washout?
For most people irrigation runs for hours, not days. It can go on longer when the scraped area was wide, when the person takes blood thinners, or when bleeding picks up again. A longer run is not by itself a sign that something has gone wrong.
What a hand washout is
If a clot does block the catheter, a nurse or doctor uses a large syringe to push a little salt water in and draw the clot back out. This is called a bladder washout. It is uncomfortable for a minute or two and often gives immediate relief. It may be repeated. If clots keep forming, the surgeon may change the catheter for a wider one or, less often, return you to theatre to stop the bleeding point.
What this page cannot tell you
It cannot tell you how long your own irrigation will run, or whether your colour today is normal for your operation. The team at the bedside can see the bag, knows what was removed and knows your medicines. Ask them directly. It is a fair question and they expect it.
Commonly believed
What do families worry about, and what is actually true?
"The red bag means he is losing a lot of blood."
A few drops of blood turn a large bag of water red. The colour looks far worse than the actual blood lost. The team watches the colour closely and checks blood counts if they are concerned.
"She must not drink water, or the bladder will burst."
The catheter drains the bladder continuously, so it does not fill up. Unless the team has told you to limit fluids for another reason, drinking normally helps dilute the blood.
"The urge to pass urine means the catheter has slipped."
The balloon and tube sit against a sensitive area, so a constant urge and short cramps are common. Tell the nurse if they are strong, because medicine can calm the spasms.
"Pink urine at home means the operation failed."
Pink urine on and off for a week or two after going home is common as the scab loosens. Dark red urine, clots or no urine at all is different and needs a same-day check.
On the ward
What do the words the nurses use mean?
- CBI
- Continuous bladder irrigation. The steady flow of salt water through the catheter.
- Three-way catheter
- A catheter with a separate channel for fluid in, fluid out and the balloon.
- Clot retention
- Clots blocking the catheter or bladder outlet so urine cannot drain. It needs attention straight away.
- Washout
- Clearing clots by hand with a syringe through the catheter.
- Input and output
- The record of fluid run in against fluid drained, which shows the catheter is flowing freely.
- Trial without catheter
- Removing the catheter and checking that you can pass urine properly on your own.
Questions we are asked
Common questions about bladder irrigation after TURBT
Does bladder irrigation hurt?
The fluid itself does not hurt. Most people feel a constant urge to pass urine and some have short cramps, called bladder spasms, because of the catheter. These can be eased with medicine, so tell the nurse rather than putting up with them. Sharp, building pain with a swollen belly may mean a blockage and needs checking at once.
Can I walk around while it is running?
Usually you can sit up and move in bed, and many people walk to the bathroom with help and the stand wheeled alongside. Keep the drainage bag below the level of your bladder so it drains well. Ask the nurse before getting up the first time, because anaesthetic can leave you unsteady.
Will I go home with a catheter?
Most people do not. The catheter usually comes out before discharge once urine is running light. Sometimes it stays in for longer, for example when a large area was scraped or the bladder wall was thinned. If so, the team will show you and a family member how to care for it and when to return.
Can I eat and drink normally during irrigation?
In most cases yes, once you are fully awake and the team says so. Water is especially helpful. If you have heart or kidney problems, you may be given a fluid limit instead, so follow what your own team tells you. Tea and coffee can irritate the bladder, so plain water is the easier choice.
My father takes blood thinners. Does that change things?
It can mean more oozing and a longer time on irrigation. Blood thinners are usually paused and restarted on a plan agreed between the surgeon and the doctor who prescribes them. Never stop or restart them on your own. Make sure every doctor involved knows exactly which medicines he takes.
Why is my urine still pink after the catheter came out?
The raw patch inside the bladder takes a few weeks to heal fully. A little bleeding on and off is common, especially when the scab comes away, often around the second week. Drink water steadily and avoid heavy lifting. Dark red urine, clots or being unable to pass urine need a same-day check.
Is irrigation the same as chemotherapy into the bladder?
No. Irrigation uses plain sterile salt water and only washes. Some people also receive a single dose of chemotherapy liquid into the bladder soon after TURBT, which is held for a while and then drained. That is a separate step with its own reasons, and it is not given while heavy irrigation is needed.
Is it a sign the operation went badly?
No. Irrigation is a routine precaution after many TURBTs, and needing it tells you nothing about the cancer or the result. The pathology report on the removed tissue is what tells you about the tumour. That usually takes some days and is discussed at a follow-up appointment.
