There is NO ROLE for ANY imaging in PNE, or for that matter, for another nerve compression syndrome in the wrist = Carpal Tunnel Syndrome!!
When I went to Dr. Antolak he recommended MRI just to rule out anything obvious that could be a problem. I had already had a lumbosacral MRI but he also wanted me to have an MRI of the lumbosacral plexus. Dr. Bautrant's publication mentioned a possible radiculo-medulllary etiology (affecting the spinal cord and nerve roots).

What are your thoughts on that?

I would also be interested to hear your thoughts on Dr. Hollis Potter's protocol for 3TMRI that has settings that give enhanced imaging of the pudendal nerve. On our forum, we haven't heard of many people who had MRI imaging that accurately diagnosed pudendal nerve entrapment, although some people who have had an MRI using Dr. Potter's protocol showed a clear nerve entrapment.

PNE since 2002. Started from weightlifting. PNE surgery from Dr. Bautrant, Oct 2004. Pain now is usually a 0 and I can sit for hours on certain chairs. No longer take medication for PNE. Can work full time and do "The Firm" exercise program. 99% cured from PGAD. PNE surgery was right for me but it might not be for you. Do your research.

kimc, do you see 90% improvement in pain from sitting as well? Did Dr E give any instructions on post surgery rehabilitation regarding how much to sit, whether you should do PT, etc? Also did you experience any post surgical numbness? Finally, what do you think of the traditional laparoscopic approach used by surgeons like Dr Bollens or Dr Bautrant versus using Da Vinci robot?

I’ve had the surgery myself and am currently experiencing some partial numbness and allodynia in the region that was not present pre surgery. Whereas you seem to have the opposite experience.

kimc,

I'm so sorry it took so many years for you to get relief. Many many thanks for sharing your story and all this information about the benefits of the robotic approach. I've learned a lot from this.

Dr. Antolak, now retired, was a gem of a physician and one of the few Urologists who tried to understand and treat this condition. Born in the era he was, he ultimately adopted the surgical techniques of that era and helped many patients with the external approach thru the perineum and transgluteal areas. I believe that will end up having limited success due to visualization of the area. But, there may be some surgeons who have great vision with surgical loupes ( generally 3 x magnification) and very steady hands. Best results published were in the 80th percentile with Dellon and I believe one other. The French MD paper mentioned in Violets note was approximately 66% for good to excellent results.

Dr. Antolak is the one who after years of clinical experience touted the simple physical exam as the best way to determine if you have a significant nerve compression in the pudendal territory. It is simple. In males touch the area of the glans penis, shaft of penis, scrotum, perineum, peri-anal area and inner butt cheeks, and sometimes even lateral to that. If it feels amplified or even painful, you have nerve compression. Then scratch lightly with a pin if you are not sure. If it feels amplified in sharpness or pain, you have a compressed pudendal nerve. In Females, it is the same exam, just substitute the Clitoris and the labia Minora for the Glans Penis and Penis shaft.

It is not uncommon for this to be bilateral, though one side can be worse than the other. Dr. Antolak reports this in his article that encapsulated his career experience with this painful nerve compression.
https://onlinelibrary.wiley.com/doi/abs ... /nau.25555

Since the quality of clinical exam in Modern Medicine is often deficient, I suggest any of you suffering from this check yourself. Don't expect the average MD to know this without you pointing it out to them. AND, if you have this, you already have the most important diagnostic test that tells you that there is a Pudendal nerve compression. If they want more proof, the lidocaine block Antolak used to do is one way to verify the source of your pain and can be done under fluoroscopy with relative ease.

There is no MRI protocol to date that will lead to MR neurography being a sensitive diagnostic test. 2 reasons. The nerve is SKINNY and really hard to see on a 3T Tesla MRI. I had mine on 6/2024 at Northwestern MRI with top people. From what they could see of the skinny nerve, everything was fine. But it wasn't. The 2nd reason is likely more important. The nerve is mostly compressed when you are in the sitting position. In that position, the SS and ST ligaments are "scissoring" the Pudendal Nerve. That is a "dynamic" compression and stretching of the nerve that will not show on an MRI in the supine position.

In terms of my results. I feel I am 90% better since surgery as I can tolerate sitting well and even lying her typing. I have no discomfort anymore at all on the right and I at most get to a 3/10 on the left if I really "abuse" it by prolonged sitting or lying on my back and typing. But that is the worse it ever gets, and I can take that easily. Most of the time, when I am not abusing it by prolonged sitting or lying, I don't even notice it as a 1/10. That result is life changing for me and I also feel that I am having further improvements on the left as the weeks go by.

I am sitting freely, shifting my weight as needed and do not feel restricted. Yesterday I was 2 hours in the car, sat and watched a 4 hour football game and 2 hours back in the car again. Minimal discomfort that did not require me to do anything special save for occasionally shifting my weight. That would have been torture even a few months ago.

There has been good results from the laparoscopic approach. Dr. Erdogru had 81% good to excellent results with that approach in his 14 case series in 2014. However, the visualization and steadiness you get with Da Vinci is markedly superior. I see no reason to approach this without a robotic laparoscope and there will be more and more surgeons abandoning Laparoscope for Robotic laparoscope due to the better visualization of everything, especially the "skinny" PN.

I forgot to mention that in the French series that I believe Violet mentioned, under complications, there were a good number of patients complaining about buttocks pain from cutting the Glute. This is commonly done in posterior hip replacements and it hurts in most cases for at least 6 weeks as it takes a long time to heal from that.

If you have a bilateral case, like I did, it should be part of your decision process. You will be moving slow for some time.

It's very interesting to read about your experience and how you have related the management of pudendal nerve entrapement in relation to the literature.

In the UK pain consultants are still pushing steroid injections and gabapentanoids, even though as you said the evidence says this approach doesn't work. I understand that pain relief is important whilst the cause of the neuralagia is established, but it seems they do not bother to investigate further and simply dismiss it as "chronic pain" (even though these are the exact clinicians who shouldn't do this). What I don't get is how they don't seem to understand is that nerves, especially so deep do not suddenly become dysfunctional. I have uncovered despite supposedly having a national public health system in the UK, that only private patients on the whole get surgery and that is in France. I have established, there is only one surgeon in the whole country that I can find that does the surgery. UK patients have to apply for special funding, what a terrible state of affairs. I have no idea how pain consultants manage people's pain on the NHS here and my conclusion is that they simply don't bother and tell people to accept it. They seem to be obsessed with pain management programmes, even though the literature says these do not work, what a waste of time and resources, they should be spending the money on developing surgical expertise in the UK. I really don't understand how modern medicine regards pain killers as treatment, it is a conservative and essentially neglient approach in my book.

In the NHS, nerve conduction studies are rarely available it seems and you have to get these privately too. I am waiting for nerve conduction studies and I hope this test will support surgery. My surgeon will not operate without abnormal nerve conduction results. Then after all that, the case has to be made to get funding. As you said the pain with this condition is worse than hell and 10/10, 24/7.

It is good to hear of your success and it shows that there is hope.

My personal history of bilateral PNE following a Microwave Prostate Procedure in 2023 (age 50) follows along so many others who report their pain journey on this site. Because this condition does not show up even on MR Neurography, Nerve Conduction Tests, CT Scans etc, there has been inherent misunderstanding of PNE as a cause of severe chronic pain. Thanks to dedicated work from the now retired Stanley Antolak, there are clear objective clinical findings on the physical exam of ALL of these patients that have a true Pudendal nerve compression. That is simple touch and pin prick! All patients with significant PN compression will have an abnormal sensory exam of the PN. Specifically, Hypersensitivity, Dysthesia, and/or Allodynia (touch feels sharp/painful) in the distribution of the PN Branches is enough to make the diagnosis. A nerve block in Alcock's canal can be done to further confirm this, but is no longer necessary to confirm the dx.

Aside from giving patients some solace in knowing that their daily sitting, standing and often even lying down pain has a reason has a positive psychological impact Dr. Antolak's work has also has helped drive insurance companies to pay for attempts at Pudendal Nerve Decompression. Almost all nerve pain comes from nerve compression. It is to be expected that as the day goes on, the PN, trapped between S-T and S-S Ligaments will get ever escalating pain. That worsens as the day goes by, and is why most patients start out with minor pain in the am which becomes quite miserable until they can get onto their left or right side at bedtime.

Attempts have been made, primarily by plastic surgeons, some by Dr. Antolak, some by European surgeons to decompress the nerve by cutting and sometimes removing the S-S ligament and cutting the S-T ligament from an "external approach". Surgery has demonstrated these ligaments to be thickened, leathery and even ossified which trap, scissor or compress the nerve. That is why the patient cannot find a comfortable position. The initial external approach has been trans-perineal. This was followed by mainly plastic surgeons using a Transgluteal Approach. This requires cutting the gluteal muscle (s) and approach the ligaments that way. It is a painful approach but worth if if decompression achieved. These surgeries cumulatively report a reduction in pain at around 75% of the time. Generally a reduction, not full relief! Technically this is a difficult approach to get at the pathology in the ligaments and to clearly see what is the cause of pain. Worse, it makes it hard to get a wide enough surgical field to relieve all the compression points. This is further complicated by at least 13% of patients having anatomical variants in the PN distribution and this approach will make it hard to detect and relieve that ( as reported by Dellon)

Tibet Erdogru was the first to report 14 cases approached laparoscopically in 2014. This approach clearly gets better exposure, a better view of the PN and the ligaments and does not require cutting muscle. His original report showed improvement in pain level in 81% of operated patients. His results have been reproduced in various case reports since that time. Technology has improved the procedure dramatically.

What appears to be a big improvement in outcome for these patients was several MD's in Europe, one gynecologist in New Jersey( Dr. Shakiba), and Dr. Tibet Erdogru in Istanbul Turkey is Robotic Laparoscopic Surgery. With the Da Vinci Robotic approach, the surgical field is magnified and the steadiness of the instruments gives the surgeon both the excellent visualization and control needed to release the nerve from its compression points. The results of this would be expected to be in the 90 plus percentile in pain relief due to this and the obvious relationship of this occult nerve compression to the pain. The case numbers are too low to guarantee that, but the pathophysiology here is obvious and release of this compression should, over time, be little different from other nerve decompression surgeries ( Carpal Tunnel, Morton Neuroma, Lumbar Disc, etc).

The use of Da Vinci has accelerated in both Gynecology and Urology and I expect those surgeons will ultimately be the surgeons of choice for this nerve decompression procedure (neurolysis). The plastic surgeons have been limited by their "tool" and the need to approach from the outside. Even that may be improved as it becomes accepted that this is simply a nerve compression syndrome, not som vague condition. For instance, Carpal tunnel surgery can now be done as a microsurgery with a scope introduced thru the wrist. It is time to innovate as the pathology is clear.

This also explains the lack of any evidence for treatments such as Steroids, Gabapentanoids, Anti -depressants, Physical Therapy and mindfulness. While the latter can improve how one processes pain in your brain, even to near elimination of pain in a few, it will not relieve a compression pain signal from an ossified ligament rubbing on a thin nerve with the consistency of spaghetti!

Cryoablation or other forms of simply "killing the nerve" can still be done in the patients who do not respond to decompression. That is not an ideal approach, but it is far more livable than the typical pain from Pudendal Nerve (often Bilateral) Compression. I would consider that a back up position. Having had this for 23 years myself, I was prepared to do that if Dr Erdogan was unsuccessful. However, he relieved 90% of my pain as of surgery on 12/8/25 and I continue to see small improvements from there. My pain is so much less and so much more tolerable that that is no longer a consideration. I marvel as I am lying on my butt here writing this note. In months prior, I would already be facing 7/10 bilateral ischial tuberosity pain after just 30 minutes of typing this. I am sitting at 1/10.

Lastly, I have seen others who describe this pain "as hell". I can relate to that to that exact description. It is not hyperbole. 20 years of hell from a nerve compression from a burn from a microwave prostate procedure that interfered with sitting, lying and standing every day.... Sometimes you wonder how you survived it! That is not to mention all of the life threatening steroid complications I got from Steroids and the hundreds of thousands of dollars spent trying to relieve this pain and treat the complications.

In terms of cost. Plastic Surgeons typically expect cash payment and the fees I have seen mentioned in this blog represent, in my opinion, the desperation of the patients in pain and their willingness to do anything to get rid of the pain. In fact, if I had to , I would have literally paid over a million dollars to get rid of this pain. But, the severity of pain should not be the price tag for a surgery. It is the complexity and time it takes. Da Vinci Surgery should be covered by insurance in the future and be accessible to anyone with this devastating pain syndrome.

Luckily, even paying case, the charge from Dr. Erdogan was US $13,000 and the 3 day hospitalization and surgery costs was $6000. Hotel, food and Travel costs to surgery have to be added to that. I did do some touring while I was there. Some great sites to see in Istanbul!!

Is Dr Kashiba the only surgeon in the entire United States for robotic surgery? It’s hard to have hope for this condition when you have one choice that’s financially and logistically impossible. 😫😕😟😔😞😖😫

In New Zealand there is only one surgeon doing pudendal decompression. He is a neurosurgeon but does the transgluteal approach. I have tries everything conservative including my second pulsed radiofrequency recently. I've had a positive nerve block and don't have a tight pelvic floor. I now think I have to have the decompression my neurosurgeon is offering as the only alternative here is a pain clinic which is non interventional. No amount of CBT and other things they offer is going to fix this pain. Thank you for your very thorough post.

Yep, CBT is gaslighting.
