Nerve-sparing radical hysterectomy, explained | CION Cancer Clinics
A nerve-sparing radical hysterectomy removes the same cancer-bearing tissue as the standard operation, but the surgeon finds and keeps the nerves that control the bladder, bowel and sexual response. It aims to lower the chance of lasting bladder problems. It is not suitable for every cancer. This page explains which nerves are kept, how, who it suits and what to ask. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What is a nerve-sparing radical hysterectomy?
A nerve-sparing radical hysterectomy removes the same cancer-bearing tissue as a standard radical operation, but the surgeon deliberately finds and keeps the nerves that control the bladder, bowel and sexual response. The aim is to lower the chance of long-lasting bladder and bowel problems afterwards.
Why the nerves are at risk at all
A radical hysterectomy removes the tissue beside the cervix, the parametrium, because cervical cancer tends to spread into it. A network of fine nerves runs through the deeper part of that same tissue. In the classic operation, much of that network is cut along with the tissue. That is the main reason many women need a catheter for a while afterwards.
What the surgeon does differently
The surgeon identifies the nerves before cutting, separates them from the tissue that must come out, and removes the cancer-bearing tissue around them. It takes more time and a detailed knowledge of pelvic anatomy. On the Querleu-Morrow system it is recorded as type C1.
What it is not
It is not a smaller operation, and it does not mean less cancer is removed. When keeping a nerve would mean leaving cancer behind, the surgeon removes it.
Sometimes the nerves can be kept on one side only, where the cancer sits further away.The nerves involved
Which nerves does the surgeon try to keep?
These nerves work automatically. You never think about them until they stop working properly.
The hypogastric nerves
They run down from the lower back into the pelvis on each side. They help the bladder hold urine and play a part in sexual arousal.
The pelvic splanchnic nerves
They come from the lower spine and are the main nerves that make the bladder squeeze and empty. They also help the rectum empty.
The bladder branches
The two groups above join into a nerve web beside the cervix. Small branches leave it to reach the bladder, passing close to the tissue that has to be removed.
If these are cut
- You may not feel the bladder filling
- The bladder may not empty fully
- A catheter may be needed for longer
Not sure whether this applies to you?
Ask an oncologistIn the operation
How are the nerves kept during surgery?
Finding the upper nerves
The surgeon locates the hypogastric nerve on each side, lying just below the ureter, the tube from the kidney to the bladder, and gently moves it out of the way.
Separating the deep tissue
Behind the cervix, the tissue that must be removed is divided from the nerve web in layers. The blood vessels are sealed without catching the nerves beside them.
Protecting the bladder branches
In front, next to the bladder, the fine branches going to the bladder are identified and left in place while the surrounding tissue is taken.
Checking the result
The womb, cervix, parametrium and upper vagina are removed in one piece. The pathologist checks that the edges are clear of cancer.
Side by side
How does nerve-sparing compare with the standard operation?
Standard radical operation
Nerve-sparing radical operation
Nerves in the deep tissue are usually cut
Nerves are found and kept where it is safe
Bladder recovery tends to be slower
Studies suggest bladder recovery is often quicker
Can be used for larger cancers near the nerves
Suits cancers that lie away from the nerves
Operation time is shorter
Operation time is usually longer

Commonly believed
What do families often get wrong about nerve-sparing?
"Nerve-sparing means there will be no bladder problems."
It lowers the chance of lasting problems, but it does not remove it. Many women still need a catheter for a short time, because even kept nerves are handled and need to recover.
"Every woman should insist on it."
If the cancer lies close to the nerves, keeping them could mean leaving cancer behind. Removing the cancer completely always comes first, and your surgeon decides this from your scans.
"If the nerves were cut, the surgeon made a mistake."
Cutting the nerves is often a planned and necessary part of removing the cancer. Ask your surgeon to explain what was done and why, rather than assuming something went wrong.
"It needs a robot, so it is only possible in a few places."
Nerve-sparing is a surgical method, not a machine. It has been done through open surgery for many years. What matters most is the surgeon's experience with it.
On your notes
What do the words on your notes mean?
- Autonomic nerves
- Nerves that run body functions you do not control by thought, such as bladder emptying and bowel movement.
- Type C1
- A radical hysterectomy where the surgeon kept these nerves. Type C2 means they were not kept.
- Unilateral nerve-sparing
- The nerves were kept on one side of the pelvis only.
- Residual urine
- The urine left in the bladder after you pass urine. It is measured to judge whether the catheter can come out.
- Urinary retention
- The bladder cannot empty properly on its own.
Being straight with you
Who is nerve-sparing not suitable for?
Nerve-sparing is usually not suitable when the cancer is large, lies toward the back or sides of the cervix, or has grown into the tissue where the nerves run. In those cases removing the nerves with the tissue gives the clearest edge around the cancer.
What the evidence can and cannot say
Studies so far suggest nerve-sparing helps bladder recovery. Many of those studies are small, come from single centres or were not randomised, so the size of the benefit is not settled. The results also depend heavily on how experienced the surgeon is with the method.
What this page cannot tell you
It cannot tell you whether you should have a radical hysterectomy, or whether your nerves can be kept. That depends on your MRI, your biopsy and what the surgeon finds on the day. Ask whether nerve-sparing is planned, whether on one side or both, and how often the surgeon performs it.
Questions we are asked
Common questions about nerve-sparing radical hysterectomy
Will I still need a catheter after nerve-sparing surgery?
Probably for a short time. Even kept nerves are handled during surgery and take time to recover. Before the catheter is removed, the team usually checks how well your bladder empties. Studies suggest women who have nerve-sparing surgery often manage without the catheter sooner.
Is nerve-sparing surgery as safe for the cancer?
It is offered only where keeping the nerves does not mean leaving cancer behind. Studies so far have not shown a clear difference in cancer control for suitable women, but many are small. Ask your surgeon to explain why they think it is safe in your case.
Can the surgeon decide during the operation?
Yes. The plan is made from your scans, but the final decision may be taken once the surgeon sees the tissue. If the cancer is closer to the nerves than expected, they may be removed. Ask beforehand how that choice will be explained to you afterwards.
Does nerve-sparing help sexual function?
It may help with arousal and lubrication, since some of the kept nerves play a part in both. It does not change the shorter vagina that comes with any radical hysterectomy. Talk to your team about lubricants, dilators and gentle return to sex.
Can it be done by keyhole or robotic surgery?
Nerve-sparing can be done through open surgery or keyhole surgery. For cervical cancer, many teams now prefer open surgery after research raised concerns about keyhole routes. Ask your centre which route they use for this operation, and why.
Will I need radiation afterwards, and does that affect the nerves?
Some women need radiation after surgery, depending on the pathology report. Radiation can add its own effects on the bladder and bowel over time. That is one reason the team weighs carefully whether surgery or radiation is the better first treatment.
How do I know if my nerves were kept?
It should be written in your operation note, often as type C1 or as nerve-sparing on one or both sides. If it is not clear, ask your surgeon at the follow-up visit. It helps any doctor who treats your bladder later.
Does it cost more than the standard operation?
The operation usually takes longer, which can affect the cost, though the hospital stay may be similar. Aarogyasri, CGHS, ECHS and EHS are accepted, and most cashless insurers are empanelled. Call the helpline for an estimate against your own cover.
