Our patients’ stories

"Look at the guidelines." These were the words my previous urologist said when I asked him about alternatives to prostatectomy, the only procedure he recommended after a diagnosis of prostate cancer in June 2016 (Gleason Score 7a, PSA 3.86, 2 of 12 punch biopsies positive). I was 49 years old at the time.

But I was very afraid of the possible side effects of surgery. Side effects like incontinence and erectile dysfunction, which I know occurs at least 60% of the time after prostatectomy, not to mention losing the ability to ejaculate. Looking at a future of only so-called "dry orgasms", I scoured the guidelines to find alternatives. All I could find was active monitoring—I was too young for this—and radiation therapy: 8 weeks of treatment with a strict diet, plus the same drawbacks as surgery.

I began to search for other treatments. IRE seemed the most promising option—and the one with the least side effects.

At the end of October 2016, the IRE procedure was carried out by Dr. Zapf and Dr. El Idrissi—and it was completely painless. I spent the following night in the clinic. Dr. El Idrissi visited me the next day and told me everything was OK. The bladder catheter caused a bit of discomfort, but that was only to be expected. 30 hours after the treatment, I was already on the train back home, a three-hour ride. The bladder catheter was removed after 11 days by my new urologist, and the slight discomfort I felt while sitting and walking quickly disappearedbut even when I experienced this discomfort, it was tolerable.

I didn’t have any problems at all with incontinence. Just five weeks after the procedure I could get an erection again. After about two to three months, the ejaculate was again completely free of old blood, which had come from the wound in the prostate.

Then, after three months, I was able to enjoy completely normal and satisfying sex.

Conclusion: One year after IRE treatment, all urological functions (urination, erection, ejaculation) work perfectly well, my PSA value is 1.0 and all follow-up MRI showed no pathological changes. Everything is great! I would like to express my deepest gratitude to Dr. Zapf and Dr. El Idrissi for a very successful treatment and follow-up consultation, with additional nutritional and fitness recommendations.

And I am, of course, grateful to Prof. Stehlingand Dr. Zapf againfor their pioneering work in the field of IRE.

Last week was November 2, 2017. Exactly five years ago, I got a diagnosis of prostate cancer in Vienna. And with it I got my urologist’s urgent recommendation to take “the high road”radical removal of the prostateto avoid a high risk of metastases, a matter of great concern for someone my age at the time: 46.

It's funny how you can remember some dates vividly. The cancer diagnosis hit me very hard.

Over the last five years, I’ve counted so many times when I was grateful to be able to play sports without having to fear dribbles in my pants… when I didn’t have to wear incontinence pads… when I could have a couple of beers without having to go to the bathroom right away… all the times I could pee while standing and stop the flow the way it suits me.

Yes, and I have also counted many, many orgasms and ejaculations, and I appreciated them more than I ever did before.

Please excuse my straight talking, but I can enjoy all of this again now after my treatment was successful, while it was all only natural before my diagnosis.

When I go to a check-up today, the doctors don’t even realize that I had cancer. I admit it makes me smile when they want to do a palpation.

I still occasionally visit my previous urologist, not because I expect something from him, but only to show him that IRE is a successful, gentle treatment… he strongly advised against it five years ago!

That’s the IRE procedure that freed me from my cancer diagnosis on March 26, 2013. This date is also now burnt deep into my memory, almost like my birthday. It was and still is a miracle to me!

To this day, I am grateful to Professor Stehling and his great team, every time I live and act naturally like a man.


In 2016 my prostate cancer was successfully treated at the Prostate Center in Offenbach, with IRE and without any side effects. I had decided to have this new treatment after my urologist in Berlin advised me to have a radical removal of my prostate, a suggestion I was not happy with.

I was even more confident in the IRE treatment after I met the team at the Prostate Center in person. Prof. Stehling’s entire team is characterized by the highest professional standards, a readiness to answer questions and, above all, a respectful and always friendly manner.

A preliminary 3D biopsyrecommended by my Prostate Centre urologist, Dr. El Idrissihad revealed more lesions. And then all the tumors in my prostate were destroyed by IRE.

All my medical treatments and follow-up examinations have been carried out in such a way as to minimize stress. Everything was perfectly and reliably organized, and I always felt like I was in good hands.

I would like to thank the entire team of the Prostate Center in Offenbachand the Institut für Bildgebende Diagnostikfor my successful treatment and the way this has enhanced my quality of life. I would recommend this procedure to others.

To whom it may concern… My name is Florian Lungu and I'm 50 years old. I was diagnosed with prostate cancer, Gleason score 6 and 7a. I’ve lived in Las Vegas for the past 21 years. I was seeking treatment in USA since I have insurance, but I didn't like the options at all. I found out about a relatively new treatment at The Prostate Center in Offenbach, Germany, called IRE Irreversible Electroporation. The head of this clinic is Prof. Dr. M.K. Stehling. Under his supervision, and with a wonderful team of doctors, nurses and others, I received this treatment on June 29th, 2017.

Today I'm feeling great, my PSA is very low, and I have not had any side effects. I would like to express special thanks to wonderful Ms. Charlotte who coordinated everything for me… every single detail… thank you so much!
Also Dr Idrissi, you’re an amazing person! Thank you to all of you for making my treatment like a vacation and taking care of me. I totally recommend this special clinic for prostate cancer.

I was diagnosed with prostate cancer in 2016. My PSA number was 4.7. I was offered robot surgery at Skejby Sygehuse. The risk of incontinence and impotence from this type of surgery prompted me to look for alternatives, and I found the Frankfurt/Offenbach clinic that offered a NanoKnife operation. The benefits of the treatment method were obvious: a much smaller intervention and reduced risk of incontinence and impotence.

Now, a year afterwards, I can see that the physical effects of the operation are less than when I had two wisdom teeth removed a couple of years ago. And at 3, 6 and 9 months, my PSA measurements were <0; 3, <0.1 and <0.1, respectively.

I found the clinic adhered to the highest professional standards in every respect, with a very friendly staff, very focused on the patient, and can give it my highest recommendation.
