ISON Congress 2026 – Morelia, Mexico 🇲🇽
Chronic Pelvic Neuropathic Pain

Chronic pelvic pain is one of the most disabling conditions worldwide — and one of the most frequently misunderstood.
The upcoming ISON Congress in Morelia (August 7–9) will focus on chronic pelvic neuropathic pain, addressing it where it truly belongs: at the interface of neurology, neurophysiology, surgery, and clinical reasoning.
This is not a gynecological congress.
This is a neuropelveological congress.
🔹 Multidisciplinary faculty
🔹 Daily live surgeries
🔹 Live diagnostic consultations
🔹 Real patients, real reasoning, real medicine
Organized by Dr. Ana Sierra, the first woman worldwide to achieve ISON Level 3 Certification, this congress marks a major step in expanding neuropelveology throughout Latin America.
Neuropelveology is not a trend.
It is a medical necessity.

📅 August 7–9 | 📍 Morelia, Mexico

The scientific program is currently in preparation and will be published shortly.
Once finalized, the full program will be available on the ISON website, accessible via the menu on the left-hand side - https://www.theison.org/congress/

“They told me it was impossible.
They told me my patients would leave in a wheelchair.
They were wrong.”
For 25 years, more than 500 women with one of the rarest and most devastating forms of endometriosis have been treated in my center:
Endometriosis of the sciatic nerve.
This is not “back pain”.
This is not orthopedics.
This is not classical gynecology.
It is a neuropelveological disease — intraneural, vascular, progressive and potentially disabling.
Today, many talk about operating the sciatic nerve.
But recurrence and failed re-operations are increasing worldwide.
In my own series:
→ No recurrences when the nerve is completely freed and treated neuropelveologically.
→ Recovery of walking, strength and life.
This surgery is not a trend.
It is a discipline.
And disciplines are built by mastery — not by fashion.

🌍 A new chapter for Neuropelveology in Asia

I am very proud to officially welcome
Dr. Pornprom Ittiamornlert (Bangkok, Thailand)
as my fellow in Neuropelveology here in Zurich. Dr. Pornprom is a senior gynecologic oncologist and laparoscopic surgeon at Siriraj Hospital, Mahidol University – Thailand’s most prestigious academic medical center.
She will spend the next three months training with me in advanced neuropelveological diagnostics and surgery.
During this fellowship she will:
• Complete ISON Neuropelveology Certification Level 2
• Likely continue toward Level 3 – Expert Track
• Start a scientific PhD project in neuropelveology
• And become the first officially trained neuropelveologist in Thailand
Together, we are preparing the structured implementation of neuropelveology in Thailand and Asia, opening a completely new diagnostic and therapeutic horizon for patients suffering from chronic pelvic neuropathic pain, nerve entrapment and neurogenic pelvic organ dysfunction.

This is not just a fellowship.
This is the birth of a new medical discipline in Asia.

Welcome to the Neuropelveological family, dear Dr. Pornprom. 🤍

✨ Tribute to David B. Redwine — My Friend, My Colleague

Today I want to honour someone whose absence I feel every day — David B. Redwine. For more than a decade we were colleagues in the fight against endometriosis, and in the last years of his life we became very close friends.

David, Silke and I shared unforgettable moments together — including a wonderful congress in Xi’an, where we both received guest professorships. After our surgeries there — David operating on endometriosis and I performing a nerve-mapping procedure — we ended the day singing “My Way” in our scrubs. That was David: passionate, authentic, full of life.

Silke and David became true “best friends”, and I will always be grateful for the bond they shared.

We were united by curiosity — the need to understand endometriosis beyond counting surgeries or bowel resections — and by the courage to cross the borders of traditional disciplines. We also belonged to the last generation of gynecologists trained in true vaginal surgery, approaching deep infiltrating endometriosis with the same philosophy:
“Do from below what must be done from below, and from above what must be done from above.”

A warm thought also goes to Nancy Petersen, an extraordinary nurse who stood by David for many years in the OR and shared this mission with us.

David was a pioneer, a mentor, and above all a good man.
Silke and I miss him deeply.
Thank you, David — you truly did it your way.

The diagnosis is everything.
In Neuropelveology, real answers - and real results - come from precision.
This is why every patient at the Possover International Medical Center undergoes a complete, two-hour neuropelveological consultation: a detailed history, pain mapping, and a true neurological examination of the pelvic nerves and plexuses.
The 4 Pillars of Diagnosis are the foundation of effective treatment:
1️⃣ Which nerve is involved?
2️⃣ Where exactly in the pelvis is the lesion?
3️⃣ Is it neurogenic or non-neurogenic?
4️⃣ What is the underlying cause?
Only when these four questions are answered with certainty can treatment be targeted, safe, and successful.
Surgery alone is not the key — diagnosis is the key. A perfectly executed intervention will fail if the wrong nerve, the wrong location, or the wrong mechanism is addressed.
Neuropelveology exists to bring clarity where patients often receive years of wrong diagnoses, unnecessary surgeries, or misunderstandings of their pain.
Precision in diagnosis → Precision in treatment → Real improvement.

Behind the scenes of a neuropelveology consultation.
Pelvic nerve pain is complex — that’s why the consultation is long, structured, and centered on real diagnostic work.
• 360° medical history — every detail matters
• Imaging helps, but never replaces clinical reasoning
• Pelvic nerves must be examined clinically
• The diagnosis is built piece by piece — no shortcuts
• Treatment only succeeds if the diagnosis is correct
Even a perfect surgery fails if the wrong nerve or wrong location is treated.
Diagnosis is the true key to success — not surgical dexterity.

It is a pleasure to welcome Dr. Mamta Mamik from NY/USA to Zurich for a two-week immersion in Neuropelveology.
This week, we operated together on a male patient with a severe femoral nerve neuropathy caused by a mesh after inguinal hernia repair. After years of compression and axonal damage, we performed a decompression and implanted a Medtronic neurostimulator to promote axon regeneration through low-frequency antidromic stimulation, combined with a program for quadriceps muscle training.
These cases show clearly what Neuropelveology truly is: not mass medicine, not routine, not standardized algorithms - but intelligent, individualized, high-level medical reasoning. Every case is unique. In Neuropelveology, every diagnosis is earned, never given - and the success of every treatment depends on the exactness of this diagnosis. Neuropelveology is a clinical discipline built on listening to the patient. The examination of the pelvic nerves is essential, while all diagnostic tools, including imaging, remain secondary. As Jón Einarsson /Harvard Uinversity once said by assisting me in Zurich, diagnosis in this field is “detective work”: a patient and time intensive, meticulous process of synthesizing a multitude of seemingly confusing elements and reorganizing them through the lens of pelvic neuroanatomy. Only then does a clear diagnosis emerge.
Neuropelveology goes far beyond gynecology. It belongs equally to women, men, and even children. And although the field was born 20 years ago from my pioneering work in gynecology, more and more neurosurgeons and urologists are entering the discipline.
Neuropelveology is not a collateral subspecialty in Gynecology, it is a medical discipline of its own, and its future lies in bioelectronic medicine and pelvic neuromodulation.
Welcome, Mamta, to the world of Neuropelveology - a world of innovation, precision, and true medical intelligence.

From Zurich to the World — The birthplace and global center of Neuropelveology.

Sometimes, people ask where Neuropelveology truly began.
The answer is not an institution, but a journey of innovation and conviction.

I began my medical studies at 15, performed my first heart transplantation at 22, and was trained not only in gynecology — but in vascular and retroperitoneal surgery.
This background shaped my entire vision: to look beyond one specialty and unite neuroscience, pelvic surgery, and innovation.

For more than 25 years, I have dedicated my work to developing Neuropelveology — a discipline that connects the pelvic nerves, endometriosis, and cancer surgery with science and humanity.
As Einstein said: “Imagination is more important than knowledge.”
Innovation has always been the heartbeat of my career — not for prestige, but for patients who had no answers.

Today, from Zurich, we continue to train physicians from around the world through the International School and Society of Neuropelveology — to ensure that knowledge and compassion move together into the future.

🌍 Global ISON Certification – Winter 2026
For the first time, physicians can complete both ISON Level 1 (Webinar Series - € 1000) and the ISON Level 2 Hybrid Masterclass (€ 1300) entirely online - at a combined fee of only € 2000.
This program, personally led by Prof. Dr. Marc Possover, founder of Neuropelveology and Chairman of the International Society of Neuropelveology (ISON), provides the complete theoretical foundation required to understand and diagnose pelvic nerve disorders.
The hybrid Level 2 course includes live Zoom sessions, real clinical consultations, and pre-recorded surgical and cadaver dissections - offering direct insight into more than 25 years of pioneering experience.
⚠️ While these online programs provide the essential theoretical knowledge and diagnostic principles, they do not replace the in-person surgical workshop in Zurich, where Prof. Possover shares hands-on techniques and intraoperative strategies. True expertise in Neuropelveology requires years of clinical experience - and honesty toward patients.
🧠 Still, for clinicians worldwide, this is the most direct and comprehensive way to learn from the source of Neuropelveology and become ISON-certified.

✨ Today, I share with you one of the most emotional moments of my life.

I have been appointed Chevalier de la Légion d’Honneur – the highest French distinction – by decree of the President of the Republic.

This honor is far greater than a personal recognition. It is a tribute to a journey of relentless work, deep human connection, and a vision that began with one question: how can we help those who suffer, when no one else can?

From the operating room to the first steps in Neuropelveology, from pain to healing, from isolation to dignity – this path was never mine alone.

I share this with my patients, whose strength has always inspired me. With my family, who gave me the courage to persist. With my colleagues and friends around the world, who believed in a new medical frontier.

This medal does not close a chapter — it fuels the mission even more.

Merci du fond du cœur. ❤️

Bladder dysfunction, constipation, painful in*******se, or loss of sensation — these are real issues many women face after endometriosis surgery.
And they’re often linked to damage or entrapment of pelvic nerves during complex procedures.

📌 In this carousel, we break down:
✅ Which nerves are at risk

✅ How they impact bladder and sexual function

✅ The role of nerve-sparing techniques (LANN)

✅ How the LION procedure can help when damage is already present

It was a true honor to take part in the 25th Anniversary of the TGMET Center in Bangkok as a keynote speaker and faculty member.

Standing on stage with colleagues and friends — some I’ve known for decades — reminded me that science moves forward not alone, but together.

Presenting the principles and future of Neuropelveology to such an engaged audience from across Asia was a deeply meaningful moment.

My sincere thanks to Prof. Ampham, whose friendship and vision continue to inspire me, and to the entire team behind this exceptional event.

This is only the beginning.
A new chapter for Neuropelveology in Asia is unfolding — and I’m grateful to be part of it.
