Bladder and bowel function after a sacrectomy | CION Cancer Clinics
After a sacrectomy, bladder and bowel function depend mostly on which sacral nerves were kept. After a low cut, many people keep useful control. After a high cut, most manage the bladder with a catheter routine and the bowel with a planned daily routine. This page explains the options, what may recover, warning signs, and how families cope at home. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What happens to the bladder and bowel after a sacrectomy?
It depends mostly on how high the cut went and which nerves were kept. After a low sacrectomy, many people keep useful control. After a high one, most people manage the bladder with a catheter routine and the bowel with a planned daily routine.
Why the nerves matter so much
The bladder and bowel do not empty on their own. They wait for signals carried by the middle sacral nerves. Those same nerves also send back the feeling that the bladder is full or that stool is coming. When they are lost, the organs still work, but they need help to empty on time.
What changes, in practice
You may not feel the urge to pass urine. The bladder may hold more than it should, or leak when it overfills. Stool may move slowly, so constipation becomes the main problem, with leaks when it finally comes. Both can be managed well with a routine, and most people learn one before they leave hospital.
What this page cannot tell you
It cannot predict your own function. Your surgeon knows which nerves were kept, and the tests after the operation show how your bladder is actually behaving.
Managing it
What are the usual ways to manage it?
Your team will suggest the simplest option that keeps you dry, comfortable and free of infection.
Self-catheterisation
You pass a thin, slippery tube into the bladder to drain it, then take it out. It is done on a timetable through the day, and many people do it in any clean toilet.
Suits people who
- Have steady hands, or a helper
- Can sit or stand to do it
A catheter that stays in
A tube is left in the bladder and drains into a bag, either through the usual opening or through a small opening in the lower tummy. It is used when self-catheterisation is not practical.
It carries a higher chance of infection over time.A daily bowel routine
Enough water and fibre, a stool softener, and a suppository or small enema at the same time each day. The aim is to empty the bowel on your schedule, so it does not empty on its own.
Bowel washouts
Warm water is passed into the back passage through a small cone or tube, then released with the stool. It can give more control when a simple routine is not enough.

Ask an oncologistOver time
How does it change over the first year?
-
In hospital
A catheter drains the bladder while you recover. Bowel medicines start early, because pain medicines and lying in bed slow the gut further.
-
Before discharge
The catheter is removed and a scan checks how much urine stays behind. A nurse teaches you or a family member catheter care and the bowel routine until it feels manageable.
-
The first weeks at home
Timings are adjusted. Leaks and constipation are common while the routine settles. Keep a simple diary of drinks, catheter volumes and bowel movements to bring to follow-up.
-
The following months
Nerves that were bruised but not cut may recover a little. Some people need the catheter less often. A bladder pressure test may be done to guide medicines.
-
Around a year
Function is usually settled. The routine you have by now is likely to be the one you keep, and most people fit it around work and travel.
Words you will hear
What do the terms the team uses mean?
- Neurogenic bladder
- A bladder that does not empty or fill normally because its nerve supply has been damaged.
- Post-void residual
- The urine left in the bladder after you try to pass it, usually checked with a quick ultrasound.
- Clean intermittent catheterisation
- Draining the bladder yourself with a fresh catheter at set times through the day.
- Urodynamic study
- A test that measures pressure in the bladder as it fills and empties, to guide medicines and routines.
- Neurogenic bowel
- A bowel that moves slowly and gives little warning because its nerves are affected.
- Transanal irrigation
- The medical name for a bowel washout through the back passage.

When to go to hospital the same day
Go to the nearest emergency department if you have a fever or shivering with cloudy or bad-smelling urine, if you cannot pass a catheter or no urine drains, if there is fresh blood in the urine that does not clear, or if your tummy becomes swollen and hard with vomiting and no stool. Say you have had a sacrectomy. Do not wait for your next clinic visit.
Commonly believed
What do families often worry about that is not true?
"Drinking less water will stop the leaks."
It usually makes things worse. Concentrated urine irritates the bladder and raises the chance of infection, and less water makes constipation harder. Keep drinking and adjust the catheter timings instead.
"Putting a tube in every day will damage the
bladder."
Draining the bladder regularly protects it. A bladder that stays overfull is the one that stretches, gets infected and can harm the kidneys over time.
"A laxative every day will make the bowel lazy."
When the nerves are affected, the bowel already needs help. A steady, planned routine is safer than waiting several days and then taking a strong laxative that causes accidents.
"She cannot go out anymore."
Once a routine is settled, most people plan outings around it. Carrying a small kit and knowing when the bowel will open gives back a lot of freedom.
Living with it
How do families manage this at home?
The first weeks at home are the hardest, and a family member usually carries much of the load. It gets easier as the routine becomes automatic.
Setting up the home
A western toilet or a commode chair makes both routines much easier than an Indian-style toilet. Keep catheters, gloves, wipes and bowel medicines in one box near the toilet. Waterproof sheets help at night in the early weeks.
Supplies and cost
Catheters and bowel supplies are a running cost. Check before discharge which ones your scheme or insurer covers, and where you can buy the same brand near home, especially in a district town.
Who this approach does not suit
Self-catheterisation is hard for someone with poor hand control, poor eyesight or memory problems, and with no helper. A catheter that stays in, or a stoma, may then be safer. Ask your team to plan around the person, not only the nerves.
Never change or stop a bladder or bowel medicine on your own. Ask the team who prescribed it.Questions we are asked
Common questions about bladder and bowel after sacrectomy
Will I need a catheter for the rest of my life?
Not always. If the key nerves were kept on at least one side, some people need the catheter less as months pass, and a few stop. If they were lost on both sides, a lifelong routine is more likely. Your team can say more once they see how your bladder behaves after the operation.
Can a family member do the catheter for me?
Yes. Nurses teach a son, daughter or spouse the same clean technique before discharge. Many patients later learn to do it themselves once they can sit comfortably. Privacy matters, so talk as a family about who will help and how.
How do I know if I have a urine infection?
Because you may not feel burning, look for other signs: cloudy or bad-smelling urine, new leaks, fever, shivering, or feeling unwell. A fever with any of these needs a same-day check. Do not start leftover antibiotics at home without speaking to a doctor.
What should I eat to keep the bowel regular?
Plenty of water, regular meals, and fibre from vegetables, fruit, dal and whole grains help. Eating at the same times each day trains the bowel. A dietitian can adjust this if you also need to regain weight after the operation.
Is a stoma ever the better choice?
For some people, yes. If a bowel routine takes hours each day or leaks keep happening, a colostomy can give more control and freedom. It is a decision made with your surgeon, and it can be discussed even months after the first operation.
Can I travel or go back to work?
Many people do, once the routine is settled. Carry a small kit with catheters, wipes and spare clothing. Time the bowel routine before you leave home. Tell your employer what you need, such as access to a clean toilet.
Are there medicines that help the bladder?
Yes. Some calm an overactive bladder, and others help it hold more. Which one suits you depends on your bladder tests. Your urologist or surgeon will choose it and set the dose. Do not start one bought over the counter.
Does Aarogyasri cover catheters and bowel supplies?
The operation and hospital stay are usually covered by Aarogyasri, CGHS, ECHS, EHS or cashless insurance. Supplies used at home are often not included in the package. Ask your scheme desk or insurer before discharge, and keep bills for any reimbursement.
