The prostate lies close to paired structures called the neurovascular bundles.
These contain nerves and blood vessels that contribute importantly to erectile function.
Their relationship with the prostate is complex. The nerves are not simply two isolated “erection nerves”; delicate nerve fibres are distributed around the prostate and adjacent tissues.
During radical prostatectomy, these structures may be encountered very close to the area where cancer needs to be removed.
Therefore, nerve-sparing surgery requires:
The objective is to preserve functional structures without leaving cancer behind.
No.
Nerve-sparing is not an automatic step in every prostatectomy.
The decision is made individually for each side of the prostate.
Depending on the cancer and anatomy, surgery may involve:
The appropriate approach can be different on the right and left sides.
For example, if the cancer is well away from the neurovascular bundle on one side but close to it on the other side, the surgical plan may involve preservation on one side and a wider oncological dissection on the other.
Nerve preservation should be planned before entering the operating room, but the final decision may also depend on what is found during surgery.
We integrate several pieces of information.
MRI helps identify:
MRI therefore contributes to planning how aggressively the tissues around the tumour need to be dissected.
The biopsy provides information about:
These findings help estimate the biological and anatomical risk of the tumour.
PSA, Grade Group, clinical stage and other risk features are considered together rather than in isolation.
Higher-risk disease may require a wider oncological approach.
For selected patients, particularly those with higher-risk disease, PSMA PET/CT may provide additional information about lymph-node or distant disease.
It complements rather than replaces detailed local assessment.
Nerve preservation does not guarantee postoperative erections.
The likelihood of recovery also depends on:
Therefore, preoperative sexual function should be documented before surgery.
The prostate has neurovascular structures on both sides.
Therefore, nerve preservation can be:
Bilateral
Both sides are preserved when the cancer location and extent permit.
Unilateral
One side is preserved while a wider dissection is performed on the side where cancer proximity makes nerve preservation unsafe.
Non-nerve-sparing
The neurovascular bundle may need to be removed or widely dissected when necessary for cancer clearance.
This is not a failure of surgical technique.
If the cancer is close to or involves the neurovascular bundle, cancer control takes priority over nerve preservation.
Nerve-sparing is not simply “leaving the nerves behind.”
It involves carefully dissecting the tissues around the prostate while attempting to preserve the neurovascular structures.
The precise technique is individualized.
Important principles include:
Precise anatomical dissection
The tissue planes around the prostate and neurovascular bundles are identified carefully.
Appropriate fascial-plane selection
The plane of dissection can be modified according to the tumour’s location and the need for cancer clearance.
Preservation of the neurovascular bundle
Where oncologically safe, the neurovascular structures are carefully separated from the prostate.
Avoiding unnecessary traction or thermal injury
Preservation is not only about where the dissection occurs, but also about how the tissues are handled.
Maintaining cancer clearance
If the tumour extends toward the nerve bundle, the dissection is modified accordingly.
A good functional result after prostatectomy depends on more than preserving the nerves.
During RARP, other technical steps may contribute to urinary and sexual functional recovery.
Depending on the individual patient and anatomy, these may include:
These techniques should never be applied mechanically. The extent of cancer and individual anatomy determine what is appropriate.
Dr Swati Shah has specific training and experience in nerve-sparing robotic radical prostatectomy.
Her prostate cancer practice has included:
In her practice, the nerve-sparing decision is based on the individual side-specific tumour risk, rather than treating nerve preservation as an automatic step for every patient.
The principle is simple: Preserve the nerves whenever it is oncologically safe — but never compromise cancer clearance merely to preserve them.
For functional preservation, several technical details matter.
MRI, biopsy and clinical staging are reviewed together to understand the location and extent of the tumour.
The right and left sides may require different approaches.
The prostate apex is an important area for both cancer control and preservation of urethral length.
Where appropriate, preservation of functional urethral length can contribute to postoperative urinary recovery.
Preservation or reconstruction of the bladder neck is considered according to anatomy and cancer involvement.
Reconstruction of posterior supporting structures may be used as part of the surgical technique where appropriate.
The bladder and urethra are precisely reconnected after prostate removal.
Minimising unnecessary traction and thermal injury to preserved structures is an important principle.
Patients often associate nerve-sparing only with erectile function.
However, urinary continence after prostatectomy is also influenced by multiple anatomical and surgical factors.
Continence recovery depends on:
Nerve preservation may contribute to functional preservation, but continence is not determined by nerve-sparing alone.
Our detailed continence outcomes, definitions and follow-up data are presented separately.

Nerve-sparing surgery improves the opportunity for erectile recovery, but it cannot guarantee normal erections after surgery.
Recovery varies considerably between patients.
Important factors include:
Before surgery
Cancer-related
Surgery-related
After surgery
Recovery may take months and, in some men, longer.
Therefore, erectile function should be discussed as a long-term recovery process, not as an immediate postoperative outcome.
Sometimes — but not routinely on both sides.
High-risk or locally advanced disease requires particular caution because the cancer may extend outside the prostate or approach the neurovascular bundles.
In selected patients, nerve preservation may still be possible on one or both sides if imaging, biopsy and intraoperative findings indicate that adequate cancer clearance can be achieved.
In other patients, wider excision may be necessary.
For locally advanced disease, the role of surgery itself and the possibility of nerve preservation should be discussed as part of a broader multidisciplinary treatment strategy.

No.
This is one of the most important points for patients to understand.
Nerve-sparing should NOT be promised before the cancer has been properly assessed.
A surgeon may plan nerve preservation before surgery, but the final extent of dissection can depend on the tumour’s location and intraoperative findings.
The correct question is therefore not:
“Will you preserve my nerves?”
but:
“Can my nerves be safely preserved without compromising cancer control?”
That is the clinically relevant question.
The purpose of nerve-sparing is to preserve erectile function while maintaining oncological safety.
Current patient guidance from the European Association of Urology explains that nerve-sparing can reduce the risk of erectile dysfunction and may also help urinary outcomes, but that the nerves may need to be removed when the tumour is close to them to ensure cancer control.
The quality of the result therefore depends on patient selection, tumour characteristics, surgical technique and the surgeon’s ability to balance oncological and functional goals.

The robotic system provides a magnified, high-definition 3D view of the surgical field, allowing the surgeon to clearly identify delicate anatomical structures such as tiny blood vessels and important nerves. This enhanced visualization is particularly valuable during prostate surgery, where precise dissection is essential.
The system’s flexible wristed instruments can rotate and move with a range of motion that facilitates fine surgical movements in the confined pelvic space. This can help the surgeon perform accurate dissection while carefully working around critical structures.
The goal of robotic radical prostatectomy is to achieve complete cancer removal while, whenever oncologically appropriate, preserving important surrounding structures that contribute to urinary continence and sexual function.
रोबोटिक सिस्टम सर्जिकल क्षेत्र का मैग्निफाइड, हाई-डेफिनिशन 3D दृश्य प्रदान करता है, जिससे सर्जन छोटी रक्त वाहिकाओं और महत्वपूर्ण नसों जैसी नाजुक संरचनाओं को स्पष्ट रूप से पहचान सकते हैं। यह बेहतर विज़ुअलाइज़ेशन प्रोस्टेट सर्जरी में विशेष रूप से महत्वपूर्ण है, जहाँ सटीक तरीके से सर्जरी करना आवश्यक होता है।
सिस्टम के फ्लेक्सिबल रिस्टेड इंस्ट्रूमेंट्स कई दिशाओं में घूम और मुड़ सकते हैं, जिससे पेल्विस के सीमित स्थान में भी सर्जन को बारीकी से सर्जरी करने में मदद मिलती है। इससे महत्वपूर्ण संरचनाओं के आसपास सावधानीपूर्वक काम करते हुए सटीक डिसेक्शन किया जा सकता है।
रोबोटिक रैडिकल प्रोस्टेटेक्टॉमी का लक्ष्य कैंसर को पूरी तरह निकालना होता है। साथ ही, जहाँ कैंसर की स्थिति इसकी अनुमति देती है, वहाँ पेशाब पर नियंत्रण (urinary continence) और यौन कार्य (sexual function) में महत्वपूर्ण भूमिका निभाने वाली आसपास की संरचनाओं को सुरक्षित रखने का प्रयास किया जाता है।
The goal is to achieve a complete oncological resection while preserving as much functional anatomy as safely possible. Careful dissection can help maintain adequate urethral length, protect the external urinary sphincter, and preserve the nerves responsible for urinary and sexual function when oncologically appropriate.
Robotic surgery provides a magnified, high-definition three-dimensional view and wristed instruments that allow controlled, precise movements in this confined anatomical space. This can be particularly valuable during apical dissection, where even small differences in tissue planes and surgical technique can influence postoperative outcomes.
However, functional preservation should never compromise cancer clearance. The prostate and involved tissues must be removed completely with appropriate oncological margins based on the patient’s tumour characteristics.

Seeking the best possible medical care, the family consulted with Dr. Swati Shah, an expert Robotic Uro-Gynec Oncologist.
After a thorough consultation, Dr. Shah recommended a Robotic Radical Prostatectomy. The family agreed, and the advanced, minimally invasive surgery was a complete success. Highlighting the rapid recovery associated with robotic procedures, the patient was remarkably discharged from the hospital just two days after the operation.
Vikram reports that all medical tubes and stitches have now been safely removed. His father is experiencing no complications and is feeling significantly better post-surgery.
Dr Swati Shah has been performing robotic prostatectomy since 2013 and has personally performed 627 robotic radical prostatectomies.
Her prostate cancer surgical experience includes:
In the analysed surgical series, approximately:
50% — bilateral nerve-sparing
20% — unilateral nerve-sparing
30% — non-nerve-sparing
These figures reflect the disease mix and surgical indications in the analysed cohort and should not be interpreted as a target percentage for nerve preservation.
The appropriate approach is decided separately for each patient.
No. Nerve-sparing refers to preservation of the neurovascular structures when this can be done safely. The prostate and cancer-containing tissue are still removed according to the required oncological operation.
Not necessarily. The appropriate approach depends on the cancer on each side. Bilateral preservation may be possible in some patients, while unilateral or non-nerve-sparing surgery may provide safer cancer clearance in others.
It can be considered in selected cases, but Grade Group alone does not determine nerve-sparing eligibility. MRI, tumour location, stage and other clinical information are important.
Sometimes. T3 disease requires careful assessment of extracapsular extension and its relationship with the neurovascular bundle. The decision is individualized.
No. Nerve preservation provides an opportunity for erectile recovery but does not guarantee it. Preoperative erectile function, age, health, tumour extent and postoperative rehabilitation all influence recovery.
Recovery varies considerably. Some men recover earlier, while others require many months or longer. Rehabilitation and appropriate treatment for erectile dysfunction may be important.
Nerve preservation may contribute to functional preservation, but continence depends on several anatomical and surgical factors. Nerve-sparing should not be presented as a guarantee against incontinence.
The surgical plan may need to be modified. Depending on the degree of suspected involvement, the surgeon may perform partial, unilateral or non-nerve-sparing dissection to maintain cancer clearance.
Preserve function — but never at the cost of cancer control.
Every prostate cancer is different.
The decision about nerve-sparing should be based on the individual tumour, not simply on whether a patient wants nerve preservation.
A thoughtful nerve-sparing plan begins before surgery with:
PSA + Biopsy/Grade Group + MRI + PSMA PET/CT when indicated + Clinical Stage + Baseline Erectile Function
and continues in the operating room with careful, side-specific surgical judgement.
