Title: First-time inflatable penile prostheses performed under local anesthesia: a single surgeon series suggests ways to improve both the patient and surgeon experience

What this study is about:
This research looked at how using local anesthesia (numbing the surgical area only) works for putting in an inflatable penile prosthesis (IPP) — a medical device used to treat erectile dysfunction — instead of general anesthesia (being fully put to sleep)

The team reviewed more than 1,300 first-time IPP surgeries done by a single surgeon(Dr. Sung Hun Park) between 2014 and 2024.

Key Findings:

1. Local anesthesia is feasible and safe

Most patients had the procedure done using only local anesthetic (numbing medicine).
Only about 32% needed additional sedation (medicine to help relax), and no one had to switch to full anesthesia during surgery.

2. Pain control can be better than expected

The local anesthesia continued to reduce pain even after the surgery was over, helping with postoperative comfort.

3. Detects problems earlier

Because the patient is awake and can feel some sensation, the surgeon may notice issues immediately if pain suddenly changes — which can improve safety.

4. Few complications with this approach

A small number of patients (about 6%) showed mild signs of local anesthetic side effects but were treated without serious problems.

Why This Matters for Patients:

✔ Less risk than general anesthesia – patients aren’t fully asleep, which is safer for many, especially older adults.
✔ Less pain after surgery – local anesthesia can help reduce the need for strong pain medicine later.
✔ Faster recovery and comfort – patients may feel better sooner after the procedure.
✔ A modern surgical option – showing that IPP surgery can be done effectively with refined anesthesia techniques.

Inflatable Penile Prosthesis Under Local Anesthesia: A Safer Option for Erectile Dysfunction Surgery

A recent study published in the International Journal of Impotence Research examined whether inflatable penile prosthesis (IPP) surgery can safely be performed using local anesthesia instead of general anesthesia.

This research reviewed more than 1,300 first-time penile implant surgeries performed over a 10-year period by a high-volume specialist in erectile dysfunction surgery (Dr. Sung Hun Park).

What Is an Inflatable Penile Prosthesis?

An inflatable penile prosthesis (also called a penile implant) is a medical device placed inside the penis to treat severe erectile dysfunction (ED) when medications like Viagra or injections no longer work.

It is considered the most reliable long-term solution for ED.

Can Penile Implant Surgery Be Done Without General Anesthesia?

The study found that:

Most patients successfully underwent penile implant surgery using local anesthesia only (numbing medication).
About 32% required light sedation for comfort.
No patients needed to convert to full general anesthesia.
Pain control continued even after surgery, improving recovery comfort.
Complication rates remained low and manageable.

Why This Matters for Men Over 50 with Erectile Dysfunction

Many men in their 50s, 60s, and older worry about risks from general anesthesia — especially those with:

Diabetes
Heart disease
High blood pressure
Previous surgical complications

Using local anesthesia for inflatable penile prosthesis surgery may offer:

✔ Lower anesthesia risk
✔ Faster recovery
✔ Better postoperative pain control
✔ Greater surgical safety monitoring
✔ Reduced nausea and grogginess after surgery

For men searching “safest penile implant surgery” or “penile implant without general anesthesia,” this study provides strong reassurance.

What This Means for Patients Looking for an Expert Penile Implant Surgeon

High-volume experience plays a major role in outcomes for inflatable penile prosthesis surgery. This study reflects extensive clinical experience and refined surgical protocols developed over many years.

This article, published in the International Journal of Impotence Research (a Nature journal), highlights a major breakthrough in men’s health led by Dr. Sung Hun (Sean) Park.

The study, titled “First time inflatable penile prostheses performed under local anesthesia: a single surgeon series,” explores a more patient-friendly way to perform penile implant surgery.

A Gentler Approach to Restoring Intimacy

For many years, getting an inflatable penile prosthesis (IPP)—the “gold standard” permanent solution for erectile dysfunction—required general anesthesia. This meant being fully “put under,” which often involves longer recovery times and higher risks, especially for older patients or those with other health issues.

Dr. Sung Hun Park’s research proves that this surgery can be done safely and effectively using only local anesthesia. Key takeaways from the article include:

No Need to Sleep: Patients can remain awake and comfortable during the procedure using specialized numbing techniques.
Faster Recovery: Because the body isn’t processing heavy sedative drugs, patients typically recover faster and can return home sooner.
Improved Surgeon Precision: Dr. Park’s “single surgeon series” shows that performing the procedure this way allows for a highly controlled environment, potentially improving the overall experience for both the doctor and the patient.
Proven Success: The study demonstrates that this method doesn’t sacrifice the quality of the result; patients still achieve the same high levels of satisfaction and device reliability.

New Breakthrough in ED Surgery: Penile Implants Under Local Anesthesia by Dr. Sung Hun Park

A groundbreaking study recently published in the journal Nature (International Journal of Impotence Research) is changing the way men approach permanent solutions for erectile dysfunction. Led by Dr. Sung Hun (Sean) Park, the research confirms that Inflatable Penile Prosthesis (IPP) surgery can now be performed successfully under local anesthesia.

What This Means for Patients

For decades, a penile implant was considered a major surgery requiring general anesthesia (being “put to sleep”). Dr. Park’s study, “First time inflatable penile prostheses performed under local anesthesia,” proves there is a safer, faster, and less invasive way.

Key Benefits of Dr. Park’s Local Anesthesia Technique:

Reduced Medical Risk: Ideal for older patients or those with heart and lung conditions who want to avoid the risks of general anesthesia.
Faster Recovery Time: Patients are often more alert and mobile immediately following the procedure, leading to a quicker return to daily life.
High Patient Satisfaction: The study shows that performing the surgery while the patient is awake (but numbed) does not compromise the success or the function of the implant.

Understanding Penile Implants Under Local Anesthesia

If you’re dealing with erectile dysfunction (ED) that hasn’t improved with pills, injections, or other treatments, a penile implant—also called a penile prosthesis—might be an option. This is a surgical device placed inside the penis to help achieve erections. The article from the International Journal of Impotence Research (published online in 2025) looks at over 1,300 first-time surgeries for inflatable penile prostheses done under local anesthesia, all performed by Dr. Sung Hun Park, a leading specialist in penile implant surgery at Stand Up Prosthetic Urology Center of Excellence for Penile Implants in Seoul, Korea. Dr. Park’s work highlights how this approach can make the procedure safer, less painful, and more comfortable for both patients and surgeons.

What Is an Inflatable Penile Prosthesis?

Think of it like an internal pump system: It includes cylinders in the penis, a pump in the scrotum, and a reservoir (fluid holder) usually in the abdomen. You squeeze the pump to inflate the cylinders for an erection and release it to deflate. It’s a reliable fix for severe ED, with high satisfaction rates, but surgery always carries some risks.

Why Local Anesthesia Instead of Being Put to Sleep?

Traditional penile implant surgery often uses general anesthesia (knocking you out) or spinal blocks, which can lead to more recovery time, nausea, or other side effects. Local anesthesia means numbing just the surgical area with injections, like at the dentist but for the groin and penis. Dr. Sung Hun Park pioneered and refined this method for penile implants, performing 1,334 first-time procedures from 2014 to 2024 without needing to switch to deeper anesthesia in any case. This keeps you awake but comfortable, reduces opioid painkillers afterward, and lets the surgeon spot issues early if you feel sudden pain.

How the Procedure Works

Dr. Park used a mix of two numbing drugs (lidocaine and ropivacaine) injected in two stages with a thin needle. On average, he used about 36.5 mL of the mixture—enough to block pain without overdoing it. Some guys (about 32%) needed light sedation (like anti-anxiety meds) to relax, especially if the reservoir was placed in a non-standard spot (called ectopic placement, done in 184 cases). But no one had to go under full anesthesia.

Key Results: What Happened to the Patients?

Success Rate: All surgeries went smoothly under local anesthesia—no major complications requiring a change in plan.
Pain Management: The numbing lasted longer than expected (beyond the drugs’ normal half-life), providing built-in pain relief after surgery. This means less need for strong pain meds, which is great for avoiding addiction or side effects.
Side Effects: A small number (6.2%, or 82 guys) had mild symptoms from the numbing drugs spreading too far (called local anesthetic systemic toxicity, or LAST), like dizziness or ringing in the ears. These were handled easily without hospital stays. Only two cases were moderate and needed a quick IV med to calm things down.
Benefits for You: Faster recovery, lower risks from full anesthesia, and the ability to give feedback during surgery if something feels off. Dr. Park notes that pain signals can act like an “alarm” for potential issues, improving safety.

How It Improves the Experience

For patients: Less overall pain, quicker return to normal life, and personalized care—everyone’s pain tolerance is different, so local lets the team adjust on the fly. For surgeons like Dr. Sung Hun Park, it simplifies the process and reducing operating room time.

Who Might Benefit?

This is especially relevant for men with ED from conditions like diabetes, prostate issues, or aging. If you’re considering penile implant surgery, Dr. Sung Hun Park’s expertise at the Sewum Prosthetic Urology Center in Seoul makes him a go-to specialist for minimally invasive options like local anesthesia penile prosthesis implantation. His series shows it’s safe even for first-timers, with low complication rates.

If you’re researching “penile implant specialists” or “local anesthesia for ED surgery,” Dr. Sung Hun Park’s techniques could be a game-changer. Always talk to a urologist for personalized advice, as results can vary based on your health. The full study is available on Nature.com for more details.

The article is about first-time inflatable penile prosthesis surgery performed under local anesthesia for men with erectile dysfunction. The abstract says Dr. Sung Hun Park and colleagues reviewed 1,334 first-time IPP cases done by Dr. Sung Hun Park from 2014 to 2024 and found that the approach was feasible, with no intraoperative conersion to regional or general anesthesia and generally manageable safety outcomes.

This study looks at a surgical option for men with severe erectile dysfunction when pills, injections, or vacuum devices are not enough.

Instead of putting every patient fully to sleep, the surgeon performed the implant surgery using local anesthesia, sometimes adding light sedation if needed.

The main takeaway is that inflatable penile prosthesis surgery can be done successfully under local anesthesia in many patients, which may improve comfort, recovery, and the overall experience for both patient and surgeon.

What the study found

The team reviewed 1,334 first-time inflatable penile prosthesis procedures.
31.7% of patients needed additional conscious sedation.
No patients needed conversion to regional or general anesthesia during surgery.
Mild local anesthetic systemic toxicity, like dizziness or ringing in the ears, was reported in 6.2% of cases and handled easily.

What it means for patients

For the average man, this means penile implant surgery may be a practical, well-established treatment for severe erectile dysfunction, and in some centers it can be done without full general anesthesia.

That can matter because many patients want a treatment that is effective, discreet, and easier to recover from.
