Most people know the term stent in the context of heart diseases. What is little known, however, is that stents are becoming more and more established in the therapy of erectile dysfunction. The stent implantation for erectile dysfunction eradicates arteriosclerotic erectile dysfunction in more than 75 percent of cases.
Erectile dysfunction often results from circulatory disorders (more on that: causes for erectile dysfunction). So, it’s all the more obvious to restore the blood flow of the penis in order to treat erectile dysfunction. Medical practitioners speak of revascularization of the penis arteries by means of balloon-tipped catheter. To put it simply: ´The arteries supplying the penis are dilated and stabilized. That sounds more complicated than it is.
Stent implantation is suitable for all men whose erectile dysfunction results from insufficient blood supply due to arterial obstruction in the pelvic and penis arteries. An individually applicable assessment can only be made after a precise diagnosis of erectile dysfunction. If, for example, the diagnosis shows that the penis arteries are not yet excessively damaged, shock wave therapy for erectile dysfunction may be the better choice for many men.
The success rate of stent implantation for erectile dysfunction is currently about 60 percent on average. However, these data are based on comparatively small pilot studies. The institute for erectile dysfunction is currently part of a major study that will be published soon. According to the current status of the evaluation (May 2018), the study confirms a success rate on an improvement of the erection of more than 75 percent.
Prof. Nicolas Diehm and his colleagues assess the result as encouraging. All the more, as complications during stent implantation for erectile dysfunction are very rare. However, just the same as with stents in other blood vessels, an arterial reobstruction can occur. This risk is the greater, the stronger the vessel has already been damaged. Therefore, it is of great importance to detect circulatory disorders as early as possible in order to initiate a promising treatment in time.
The stent implantation of the penis arteries is not a surgery but a minimal-invasive intervention. Under local anesthesia a small incision is made in the groin. Via this access, a catheter is guided over the pelvic artery to the penis arteries. Via the catheter, the obstructed artery is dilated with a balloon. Subsequently, a stent is implanted to stabilize the constriction.
01. Between the two arrows, a strong obstruction (stenosis) of the left penis artery (arteria pudenda interna) can be detected. This is the reason why the penis is not sufficiently supplied with blood.
02. This picture shows the same artery while it is dilated with a balloon. Medical practitioners refer to this method as balloon dilatation or balloon angioplasty.
03. After the dilatation by the balloon, the dilated artery can again collapse a bit. Hence, it remains a stenosis. The next step is to stabilize this so-called residual stenosis with a stent.
04. After the successful stent implantation the obstruction is eradicated. In order to avoid a restenosis as best as possible, the stent is coated with medication.
The founders of the institute for erectile dysfunction, Prof. Dr.med. Nicolas Diehm, PD Dr. med. Hak Hong Keo and Dr. med. Christian Regli as well as their partner Dr. med. Martin Christian Schumacher (urologist) are internationally recognized pioneers in the angioplasty treatment of erectile problems. For more information about their scientific work and further literature see News.
After well over four hundred interventions, Prof. Diehm describes the stent implantation for erectile dysfunction as a routine intervention. Currently, he carries out this intervention up to 20 times per month.
