Single-port robotic prostatectomy
Robotic removal of the whole prostate and seminal vesicles for prostate cancer, done through one small cut of about 3 centimeters (just over an inch) instead of several keyholes, using the da Vinci SP single-port robot.
Also called SP prostatectomy, SP-RARP, Single-port RARP, da Vinci SP prostatectomy, Single-incision robotic prostatectomy, Extraperitoneal single-port prostatectomy, Transvesical prostatectomy, Transvesical single-port prostatectomy

Overview
This is the same cancer operation as a standard robotic radical prostatectomy. The whole prostate and the seminal vesicles, two small glands attached to its back, are removed, often with nearby lymph nodes, and the bladder is sewn down to the urethra, the tube that carries urine out through the penis. What changes is the doorway. Instead of about six keyhole cuts across the belly, everything goes in and out through one small cut, usually just below the belly button.
The da Vinci SP (single port) system, made by Intuitive, was cleared by the U.S. Food and Drug Administration for urologic surgery in 2018. Its one arm passes a single tube about 1 inch (2.5 centimeters) wide into the body. Out of that tube come a 3D camera and three thin instruments with elbows and wrists that spread apart inside, like fingers opening from a closed hand. Your surgeon sits at a console in the same room and controls every movement. The robot never moves on its own.
Because everything enters at one spot, surgeons can choose routes that are harder with the standard robot. Many stay in the space in front of the bladder, outside the peritoneum, the thin lining that wraps the bowel. This is called the extraperitoneal route. Others go through the bladder itself (transvesical) or through the belly as in standard surgery (transperitoneal). Staying outside the belly lining means the bowel is not touched, which may allow less head-down tilt, less gas pain, earlier eating, and an easier operation for men with scar tissue from earlier belly surgery.
Be clear about the evidence. Studies so far come mostly from experienced centers comparing their own patients. They suggest cancer control, urinary control and erection recovery similar to standard multiport robotic surgery, with less pain medicine and more men going home the same day. Few randomized trials have compared the two, and long-term results are still being collected. Fewer surgeons have this robot, and your surgeon's experience matters more than the model of robot.
The parts of your body involved
The prostate is a walnut-sized gland that sits just below the bladder and in front of the rectum, deep behind the pubic bone. The urethra runs straight through its middle, so removing the prostate means cutting the urethra above and below it and joining the bladder to the lower urethra. Just below the prostate is the urinary sphincter, the ring of muscle that keeps you dry. Thin bundles of nerves for erections run along its sides. In front of the bladder is a space filled with fat and veins, and above and behind it the bowel sits inside the peritoneum, the lining of the belly.
- Prostate
A gland about the size of a walnut that adds fluid to semen. Most prostate cancers start in its back and outer part.
- Seminal vesicles
Two small glands attached to the back of the prostate that make much of the fluid in semen. They are removed with the prostate.
- Bladder neck
The funnel-shaped bottom of the bladder where it meets the prostate. After the prostate is removed, it is sewn to the urethra.
- Urethra and urinary sphincter
The urethra carries urine out through the penis. The sphincter is a ring of muscle around it, just below the prostate. Protecting it is the key to urinary control.
- Erection nerves
Thin sheets of nerves and small vessels, called neurovascular bundles, along both sides of the prostate. They are needed for natural erections.
- Peritoneum
The thin lining that wraps the bowel and other belly organs. The extraperitoneal route stays outside it, in the space in front of the bladder.
Why it’s done
The reasons to remove the prostate are the same as for any radical prostatectomy. The single-port approach is a way of doing that operation, chosen when your surgeon has the robot and the experience, and when your body and your cancer suit it.
- To cure cancer inside the prostate
For intermediate-risk and many high-risk cancers that have not spread, removing the whole prostate offers a long-term cure for most men.
- One small cut
Instead of about six keyholes, there is one cut of about 3 centimeters, often hidden at or just below the belly button. Some surgeons add one small extra opening for an assistant.
- A shorter stay and less pain medicine
Many centers send most men home the same day or the next morning. Several reports describe less need for opioid pain pills, especially with the extraperitoneal route.
- Earlier belly surgery
Scar tissue from earlier operations, such as bowel surgery or hernia repairs inside the belly, can make standard surgery slower. Routes that stay outside the belly lining or go through the bladder can avoid most of that scar tissue.
- Less head-down tilt
The extraperitoneal route usually needs a gentler head-down position and lower gas pressure than standard robotic surgery. This can help some men with lung, heart or eye conditions. Your anesthesia team will advise you.
- A complete report and simple follow-up
The whole prostate goes to the pathologist for an exact grade and stage, and your PSA blood test should fall to undetectable, which makes follow-up simple.
Other options
- Standard (multiport) robotic prostatectomy
The same operation through about six small keyholes. It is the most common way prostatectomy is done in the U.S., widely available, and has the longest track record.
- Retzius-sparing robotic prostatectomy
A multiport approach that reaches the prostate from behind the bladder and leaves the front structures in place, which may help urinary control return sooner.
- Open radical prostatectomy
The same operation through one longer cut in the lower belly. Cancer control and long-term function are similar in experienced hands, with more blood loss and a slower early recovery.
- Active surveillance
For low-risk and some favorable intermediate-risk cancers, regular PSA tests, MRI scans and repeat biopsies watch the cancer, with treatment only if it changes.
- External beam radiation
Radiation aimed at the prostate from outside the body over about 1 to 9 weeks, often with hormone therapy for higher-risk cancers. Cure rates for many cancers are similar to surgery, with a different pattern of side effects.
- Focal or whole-gland ablation
Destroying cancer with focused ultrasound, heat inside an MRI, or freezing, for carefully selected men. Side effects are usually fewer, but long-term cancer control is less certain.

The day before
The morning of surgery
In the operating room, step by step
Press play or pick a step. Each drawing shows what your surgeon is doing at that moment. Your team may do some steps differently.
1. Going to sleep and a gentler tilt
In the operating room, the anesthesiologist puts you fully to sleep and places a breathing tube. A soft catheter is placed into your bladder after you are asleep. Your arms are tucked and padded, and the table is tilted so your head is lower than your feet.
More detail
With the extraperitoneal route, the bowel stays inside its lining and out of the way, so many surgeons use a much gentler tilt than the steep position used for standard robotic prostatectomy. For the transperitoneal route, the tilt is closer to standard. The team pads every pressure point and protects your eyes either way.
The surgeon sits at a console a few steps from you and moves every instrument with hand controls and foot pedals. The robot cannot move on its own or make decisions.
A camera on one arm gives the surgeon a bright, three-dimensional picture magnified about ten times, which helps them see small nerves and vessels.
The instruments are about the width of a pencil and bend like a wrist inside your body, so the surgeon can stitch and dissect through small openings.
A bedside assistant and a scrub nurse stay at the table, and the anesthesia team watches your breathing and blood pressure throughout. Most U.S. hospitals use the da Vinci system made by Intuitive.
After the operation
Right afterward
- The recovery room
You are watched for 1 to 2 hours as you wake. A sore throat from the breathing tube is common. Facial puffiness is usually less than after steep-tilt surgery.
- Walking within hours
Nurses help you sit up and walk within a few hours. Walking eases gas pain, wakes up the bowels, and lowers the risk of blood clots.
- Eating and drinking
You can usually drink right away and eat light food the same day, especially when the bowel was not touched.
- Pain control
Most men do well with scheduled acetaminophen, sometimes with an anti-inflammatory medicine or a numbing injection at the incision, and few or no opioid pills.
- Learning catheter care
A nurse shows you how to switch between a small leg bag for the day and a larger bag for the night, and how to empty them and keep the tip of the penis clean.
- Going home
Men who are walking, drinking, comfortable on pills and confident with the catheter often go home the same evening or the next morning. If anything is not right, you stay.
At home
- Pain
Expect soreness at the single incision, most when you sit up or cough, for about 1 to 2 weeks. Hold a pillow against it when you cough. Shoulder-tip gas pain, if any, usually lasts only a day or two.
- Wound and showering
You can usually shower after 24 to 48 hours. Let soapy water run over the incision and pat it dry. Skin glue peels off on its own in 1 to 2 weeks. Avoid baths, hot tubs and swimming until the wound is healed and the catheter is out.
- Catheter care
Keep the bag below the level of your bladder. Wash the tip of the penis daily and put a little lubricant where the tube enters. Strap the tube to your thigh so it does not tug. Pink urine or small clots are common.
- Bladder spasms
Sudden cramping behind the pubic bone or at the tip of the penis, with urine leaking around the catheter, is a bladder spasm. It is common and harmless. Ask about a spasm medicine if they are frequent.
- Diet and bowels
Eat normal food as your appetite returns and drink enough to keep urine light yellow. Take a stool softener while on any opioid and avoid straining. Do not use enemas or suppositories unless your surgeon says so.
- Activity and lifting
Walk several times a day. Avoid lifting more than about 10 to 15 pounds (4.5 to 7 kilograms), hard exercise, and bicycle riding for about 6 weeks, to protect the incision and the new join.
- Driving
Most surgeons ask you not to drive while the catheter is in or while you take opioid pain pills.
- Work
Desk work is often possible in about 1 to 3 weeks, sometimes sooner from home. Heavy work usually needs about 6 weeks.
- Sex and erections
Sexual activity can resume when you feel ready after the catheter is out. Your team may start you on an erection pill or a vacuum device as part of a recovery plan.
Recovery timeline
- Day 0Surgery day
Surgery takes about 2 to 4 hours. You wake with a catheter and one small dressing and walk within hours. Many men go home that evening.
- Day 1Home
If you stayed overnight, you usually go home the next morning with the catheter and a leg bag.
- Days 2 to 7The catheter week
Incision soreness fades. Energy is low and naps help. Bowels settle back to normal.
- Days 5 to 10Catheter out
A nurse removes the catheter in clinic in a few seconds. Leakage is expected at first, so bring pads. Daily Kegel exercises begin.
- Weeks 1 to 2Pathology results
Your surgeon reviews the full lab report: grade, margins, seminal vesicles and lymph nodes.
- Weeks 3 to 6Back to most activities
Most men are back to daily routines and desk work, with heavier lifting and cycling after about 6 weeks.
- Weeks 6 to 12First PSA test
Your first PSA after surgery should be undetectable.
- 3 to 6 monthsLeakage improving
Many men are dry or need only a light pad. Erection recovery is slower and often just beginning.
- 1 to 2 yearsLong-term recovery
Most men reach their final level of urinary control by about 1 year, and erections can keep improving for 2 years or more. PSA checks continue.
What it feels like
Men who have this operation often say the first days were easier than they expected, with one sore spot instead of several. The weeks after are much like any prostatectomy: a catheter, some leaking, and waiting for results.
The night before
Many men feel a mix of dread and relief that the waiting is nearly over. Some also wonder whether choosing a newer robot was the right call.
What helpsWrite down your last questions, including how many single-port operations your surgeon has done. Set out pads, loose clothes and your recovery chair ahead of time.
Waking up
Grogginess, a scratchy throat, and a constant urge to pee from the catheter even though the bladder is empty. The incision near the belly button feels tight.
What helpsTell the nurse early about nausea or pain. The catheter urge usually fades within a day as you get used to it.
Going home the same day
Leaving the hospital a few hours after a cancer operation can feel too fast, and some men and partners feel nervous the first night. Others are simply glad to be in their own bed.
What helpsMake sure you know who to call at night and have the number saved. Have your partner or friend watch the catheter teaching too. Most worries the first night are about the catheter, and a quick phone call usually settles them.
The single incision
The one cut is the sore spot, most when you sit up, cough or laugh. Some men feel a firm ridge under it as it heals.
What helpsRoll to your side before sitting up and hold a pillow over the incision when you cough. The firm ridge softens over a few months.
The catheter week
The tip of the penis gets sore, the tube tugs when you move, and urine or blood may leak around it, especially with a bowel movement. Bladder spasms can come in waves.
What helpsStrap the tube to your thigh with some slack and use lubricant at the tip. Check that the tubing is not kinked. Ask about a spasm medicine if needed.
The day the catheter comes out
Relief, then often frustration. Most men leak when they stand, cough or lift, and more later in the day as the muscles tire.
What helpsBring pads and spare clothes to that visit. Do your Kegel exercises, cut back on caffeine and alcohol, and track pads week by week rather than day by day.
Erections and intimacy
Erections are usually weak or absent at first, even with nerve sparing. Orgasm still happens but is dry. Many men grieve this quietly.
What helpsAsk for a penile recovery plan, which may include pills, a vacuum device or injections. Talk openly with your partner; closeness does not depend on erections alone.
Waiting for the PSA
The days before each PSA test can bring back the fear you felt at diagnosis.
What helpsKnow the date of the test and when you will hear. Ask ahead of time how an undetectable result appears on your report.
How well it works
Success is measured the same way as for any prostatectomy: the cancer is removed with clear edges, the PSA becomes undetectable, and over the next year you regain urinary control and as much sexual function as possible.
- The pathology report
The lab reports the grade group, the stage, the margins (whether cancer touched the cut edge), and the lymph nodes. Reports from expert centers show margin rates similar to multiport surgery.
- PSA after surgery
The PSA should become undetectable within about 6 to 12 weeks. A PSA that later rises to 0.2 ng/mL or higher, confirmed on a second test, is the usual definition of cancer coming back.
- Urinary control
Most men improve steadily over 3 to 12 months, and most use no pad or one light pad by a year. Some reports suggest the transvesical route may bring early control back sooner, but this needs more study.
- Sexual function
Erection recovery takes 1 to 2 years and depends mostly on your age, your erections before surgery, and how much nerve tissue was kept, not on the number of ports.
- How it compares
So far, single-port surgery appears to match multiport surgery for cancer control and function in experienced hands, with fewer pain pills and shorter stays in many reports. Long-term data are still being gathered.
Risks
Every operation has risks. These are the ones people ask about most, with honest odds where good numbers exist. Your surgeon’s own results matter more than averages.
Common
Leakage with coughing, standing or lifting is expected after the catheter comes out and improves over months.
Erections weaken or stop after surgery, at least for a while. Recovery depends on age, erections before surgery and nerve sparing.
Orgasm still happens, but no fluid comes out. You cannot father a child naturally. This is permanent.
The single incision is sore for 1 to 2 weeks, more than any one keyhole would be.
Cramps and sudden urges while the catheter is in are common and usually stop once it is removed.
Some men leak a little urine at climax or notice the penis looks a little shorter.
Less common
Urine can seep through the join while it heals. It usually seals if the catheter stays in a little longer.
After lymph node removal, fluid can collect in the pelvis. A large one can cause pain, leg swelling or infection and may need draining.
A bulge can form at the single incision or in the groin in the first year or two. It can be repaired if it bothers you.
Scar tissue can narrow the connection between bladder and urethra, causing a weak stream months later. It is usually treated with a short scope procedure.
Urine infections and wound infections are uncommon and treated with antibiotics.
Clots in the leg veins or lungs are uncommon. Walking, leg sleeves and sometimes blood thinner shots lower the risk.
Rare
A small tear in the rectum is rare and is usually repaired during surgery.
Blood loss is usually low, and a transfusion is rarely needed.
These structures lie close to the work area. Injury is rare and usually repaired right away.
If the single port does not give safe access, your surgeon may add ports, switch to the multiport robot, or very rarely open surgery.
Call your care team or go to the emergency room if
- Fever of 101°F (38.3°C) or higher, or shaking chills.
- No urine draining into the bag for more than 1 to 2 hours, especially with lower belly pain or fullness. Check the tubing for kinks first, then call right away.
- The catheter falls out or slips partway out. Call your surgeon right away and do not let anyone put in a new one without speaking to your surgeon first.
- Thick blood or clots in the urine that do not clear after resting and drinking more, or that block the catheter.
- Swelling, pain or warmth in one calf or thigh. Call 911 for sudden shortness of breath or chest pain.
- Belly pain that keeps getting worse, a swollen belly, repeated vomiting, or no gas or bowel movement for 3 days.
- Redness spreading from the incision, pus, a wound that opens, or a new bulge at the incision.
- After a same-day discharge: you cannot keep fluids down, or your pain is not controlled by the pills you were given.
Questions to ask your surgeon
- How many single-port prostatectomies have you done, and what are your results for leakage, erections and margins?
- Which route do you plan for me (extraperitoneal, transvesical or transperitoneal), and why?
- Does my prostate size, a middle lobe, my weight or my earlier surgery affect whether single port is a good choice?
- Will you remove lymph nodes, and can you do that through this route?
- Will you add an extra port for an assistant?
- Can you spare the nerves on one or both sides?
- Will I go home the same day, and what happens if I need help that night?
- How long will I have the catheter?
- If you would recommend multiport surgery for someone like me, why?
- What is your plan for erection recovery and pelvic floor therapy?
- When will I get my pathology results and my first PSA?
Words you may hear
- Pneumoperitoneum
- The gas-filled belly that makes keyhole surgery possible. Carbon dioxide is pumped in through a thin needle or the first port until the belly wall lifts like a tent (usually at a pressure of 12 to 15 mmHg), giving the camera and instruments room to work. The gas is let out at the end, and the little that remains is absorbed and breathed out over a day or two; it can cause shoulder-tip ache in the meantime.
- da Vinci SP
- A single-port surgical robot that passes a camera and three bendable instruments through one tube about 1 inch wide.
- Single-port surgery
- Keyhole surgery done through one small opening instead of several.
- Peritoneum
- The thin lining that wraps the bowel and other belly organs.
- Extraperitoneal
- Working outside the belly lining, in the space in front of the bladder, without touching the bowel.
- Transvesical
- Working through the bladder: the port is placed into the bladder and the prostate is removed from inside it.
- Transperitoneal
- Working through the belly lining, as in standard robotic surgery.
- Space of Retzius
- The space between the pubic bone and the front of the bladder and prostate, filled with fat and veins.
- Seminal vesicles
- Two small glands behind the prostate that make much of the fluid in semen.
- Anastomosis
- The new join between the bladder neck and the urethra.
- Nerve sparing
- Peeling the erection nerves off the prostate and leaving them in the body.
- Foley catheter
- A soft tube through the penis into the bladder, held in by a small water balloon.
- PSA (prostate-specific antigen)
- A protein made by prostate tissue, measured with a blood test. After the prostate is removed, it should be undetectable.
- Surgical margin
- The cut edge of the removed prostate. A positive margin means cancer cells touch that edge.
- Lymphocele
- A pocket of lymph fluid that can collect after lymph nodes are removed.
Common questions
Is single-port surgery better than standard robotic surgery?
It has not been shown to be better for cancer control or long-term function. In experienced centers it appears similar, with one incision, fewer pain pills and more same-day discharges. The experience of your surgeon matters more than the number of ports.
Is one 3 centimeter cut really better than six small ones?
Many men find one cut easier to care for and less painful overall, and the scar is often hidden at the belly button. The single cut is larger than any one keyhole, so it is the sore spot for a week or two.
Can I really go home the same day?
Many centers now send most single-port patients home the same day or the next morning, when they are walking, drinking and comfortable. If you or your team are not comfortable, you stay overnight.
Does the robot do the operation?
No. Your surgeon does the operation from the console. The robot holds the camera and instruments and moves them only as your surgeon's hands move the controls.
Can lymph nodes be removed through one port?
Yes, with the extraperitoneal and transperitoneal routes. A full lymph node removal is harder through the bladder route, so that route is usually chosen for men who do not need extended node removal.
Will I leak less than after standard surgery?
Long-term leakage appears similar. Some reports suggest earlier control with certain routes, but this has not been proven in large trials.
What if my surgeon cannot finish through one port?
Your surgeon may add a port or switch to the multiport robot. This is uncommon, and it is done for your safety. Ask about it before surgery so it does not come as a surprise.
