When passing urine is hard after the catheter comes out | CION Cancer Clinics
It is common for the bladder to be slow to start working after a catheter is removed, especially after pelvic surgery. Swelling, medicines and nerves near the operation all play a part, and most people recover. If you cannot pass any urine for several hours and your belly feels full or painful, get checked the same day. This page explains why it happens and what comes next. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Why can you not pass urine after the catheter comes out?
It is common for the bladder to take a little while to start working again once a catheter is removed. If you cannot pass any urine for several hours and your lower belly feels full or painful, tell the nurse or call the hospital the same day.
What has happened to the bladder
While the catheter was in, the bladder did not have to fill or squeeze. It drained all the time. After removal it has to relearn a job it has not done for days. The tissue around the outlet may also be swollen from the operation, and anaesthesia or strong pain medicines can slow the message from the bladder to the brain. Most people pass urine within the first few hours. Some need longer, or need help for a short time.
This is not a failure on your part
Families sometimes feel the patient is not trying hard enough. That is not how it works. You cannot force a bladder that is not ready. Stay calm, keep sipping fluids as advised and let the team check you.
Your ward may call this a "trial without catheter". It simply means the team is watching to see how your bladder copes.

Do not wait at home if
You have passed no urine for several hours, your lower belly is swollen or painful, or you feel an urge you cannot relieve. Go to the hospital or the nearest emergency department the same day. The same applies if you have a fever, shivering or blood clots in your urine. Do not drink large amounts of water to force it out, as that fills the bladder further.
Not sure whether this applies to you?
Ask an oncologistHour by hour
What usually happens after the catheter is taken out?
-
The catheter is removed
This is often done early in the morning, so the team has the whole day to watch. It takes a few seconds and feels strange rather than sore.
-
You drink normally and wait
You are asked to drink as you usually would. You may be given a jug or bottle to pass urine into, so the nurse can see how much comes out.
-
The first time you pass urine
It may sting, look pink or come out in a weak stream. That is common at first. Tell the nurse each time you go.
-
A quick bladder scan
A nurse places a small scanner on your lower belly. It shows how much urine is left inside after you have been. It does not hurt and needs no needle.
-
The team decides the next step
If you are passing urine well and the bladder empties, you carry on as normal. If not, a catheter may go back in for a few more days, or you may be taught to drain the bladder yourself.
Why it happens
What makes it hard to pass urine after surgery?
Usually more than one of these is at work. Most are temporary and improve as you recover.
Swelling after the operation
Surgery on the prostate, bladder, womb, rectum or nearby lymph nodes can leave the outlet of the bladder swollen for a while.
Medicines
Anaesthesia and strong painkillers, such as morphine-type medicines, can make the bladder slow to respond. This usually wears off as the doses come down.
Nerves near the operation
The nerves that control the bladder run close to the pelvic organs. After a large pelvic operation they can take longer to recover, and occasionally the change lasts.
Everyday things
Several ordinary problems also play a part.
- Constipation pressing on the bladder
- Lying flat, or a lack of privacy
- An enlarged prostate you already had
- Pain when you try to push

Commonly believed
What do people often believe that is not true?
"Drink a lot of water and it will come out."
If the bladder cannot empty, extra water only fills it further and makes the pain worse. Drink normally. If nothing comes, the answer is to drain the bladder, not to add more to it.
"If the catheter goes back in, the operation has failed."
A catheter going back in for a few more days is common after pelvic surgery. It gives the swelling more time to settle. It says nothing about whether the cancer operation itself went well.
"Once it has happened, he will always need a tube."
Most people get back to passing urine normally as they heal. A small number need longer-term help. Your team will tell you which situation you are in, and when they expect to know more.
"Leaking a little means the bladder is working again."
Sometimes dribbling happens because the bladder is so full that it overflows. If you are leaking small amounts but never feel empty, tell the nurse. A bladder scan will show what is going on.
On your notes
What do the words on your discharge notes mean?
- Urinary retention
- The bladder fills but cannot empty properly on its own.
- Trial without catheter
- The planned removal of a catheter, followed by a check that you can pass urine.
- Residual volume
- The amount of urine left in the bladder after you have been to the toilet, measured with a bladder scan.
- Self-catheterisation
- Passing a thin, soft tube into the bladder yourself a few times a day to empty it, then taking it straight out.
- Suprapubic catheter
- A catheter that goes into the bladder through a small opening in the lower belly, instead of through the usual passage.
If you need more time
What if you go home with a catheter again?
Many people go home with the catheter back in and return a few days later for another try. That is a normal part of recovery for some operations, and you can manage it at home with simple care.
Learning to empty the bladder yourself
Some people are offered self-catheterisation instead. A nurse teaches you or a family member to pass a thin tube a few times a day and remove it at once. It sounds hard, but most people learn it quickly. It does not suit everyone. Poor eyesight, shaky hands, confusion or a lack of privacy at home can make it difficult, and it is fine to say so.
What this page cannot tell you
It cannot tell you why your own bladder is slow, or how long it will take to recover. That depends on the operation, the nerves involved and your health before surgery. Ask your surgeon what they expect in your case, and what the plan is if the next try does not work.
Keep a simple note of when you pass urine and roughly how much. It helps the team far more than a memory of the day.Questions we are asked
Common questions about passing urine after a catheter
How long can I safely wait to pass urine after removal?
There is no single safe number for everyone. If you are in hospital, the nurse will check you regularly. If you are at home and have not passed urine for several hours, or your belly is full and uncomfortable, call the hospital or go to an emergency department the same day.
It burns when I pass urine. Is that normal?
A mild sting for the first few times is common, because the passage is irritated from the catheter. It should ease steadily. If it gets worse, or comes with fever, shivering, cloudy or smelly urine, tell your team, as it may be an infection that needs treatment.
I keep feeling I need to go, but only a little comes out.
This can happen while the bladder settles, and it often improves over the next day or two. It can also mean the bladder is not emptying fully. Mention it to the nurse or your doctor, who may check with a bladder scan rather than guess.
Does warm water or sitting down help?
Often, yes. Men may find it easier to sit to pass urine at first. Privacy, a relaxed position, running a tap and a warm wash of the lower belly can all help the bladder let go. None of these replaces a check if nothing comes after several hours.
Can constipation really stop me passing urine?
Yes. A full bowel presses on the bladder and its outlet, and pain medicines after surgery often cause constipation. Eat fruit, vegetables and dal, drink as advised and ask for a mild laxative if you have not opened your bowels. Never strain hard after pelvic surgery.
Should I stop my prostate or bladder tablets?
Do not stop, start or change any medicine on your own. Some tablets, such as tamsulosin, affect how the bladder empties, and others can slow it down. Show the ward your full list of medicines. Your surgeon and prescribing doctor will decide what to change and when.
Will I leak urine once things improve?
Some leaking is common after certain operations, especially on the prostate, and usually improves over time. Pelvic floor exercises taught by a nurse or physiotherapist help many people. Ask your team whether they suit your operation and when to begin.
Is this covered by Aarogyasri or insurance?
Care that follows an approved cancer operation, including a catheter going back in or follow-up checks, is often covered. What each scheme pays varies. Aarogyasri, CGHS, ECHS, EHS and cashless insurance are accepted at CION. Call the helpline and we will check your own cover.
