Surgical treatment of erectile dysfunction

Surgery for erectile dysfunction comes into play when medical therapies — oral and intracavernous — fail to resolve the problem. It comprises two very different routes: microsurgical penile revascularisation, which international guidelines now reserve for highly selected cases, and penile prosthesis implantation, the definitive solution for patients who do not respond to any other treatment.

Microsurgical penile revascularisation

In the 1970s and 1980s, microsurgical penile revascularisation procedures were widely performed. The principle is the same as that of a coronary bypass: when a penile artery is obstructed, the surgeon attempts to bypass it, exactly as is done with an obstructed coronary artery in the heart.

The techniques used include:

• Femoro-pudendal and epigastric-cavernous bypass
• Double epigastric-cavernous bypass
• Arterialisation of the deep dorsal penile vein
• Ligation of the deep dorsal penile vein, in cases of venous leakage

The limitation lies in the results. These procedures have not produced outcomes that are reliable and stable over time. For this reason, international guidelines now reserve revascularisation surgery for highly selected cases: typically young men with an isolated arterial obstruction of traumatic origin and no generalised vascular risk factors (diabetes, hypertension, diffuse atherosclerosis). In patients with diffuse vascular damage — the large majority of organic ED — revascularisation is not indicated.

The penile prosthesis

For patients who do not respond to medical therapy and in whom revascularisation is not indicated, the surgical solution is penile prosthesis implantation. It carries the highest satisfaction rate of all erectile dysfunction treatments, but it is also an irreversible choice: the implant permanently replaces the erectile tissue of the corpora cavernosa, and a return to drug therapy is no longer possible afterwards.

When surgery becomes the option

The treatment pathway for erectile dysfunction is stepwise, and surgery is the final step:

• Correction of risk factors: smoking, physical inactivity, weight, control of diabetes and hypertension
• First-line medical therapy: oral PDE5 inhibitors
• Second-line medical therapy: alprostadil by intracavernous injection, transurethral device or topical cream, optionally with a vacuum device
• Surgery: revascularisation in selected cases, penile prosthesis in non-responsive patients

Surgery is reached only after the failure of the previous options has been established, and after a complete instrumental diagnosis has clarified which mechanism is impaired.

Frequently asked questions about erectile dysfunction surgery

Can erectile dysfunction be treated surgically?

Yes, but only in specific cases and as a last resort. The two routes are microsurgical revascularisation, reserved for highly selected cases, and penile prosthesis implantation, indicated when every medical treatment has failed.

Why is penile revascularisation so rarely performed?

Because the results have not proved reliable or stable over time. International guidelines reserve it for a narrow patient profile: young, with an isolated arterial obstruction of traumatic origin and without generalised vascular risk factors.

Is surgery the next step if the drugs do not work?

No. If oral drugs fail, the next step is second-line medical therapy (alprostadil by injection, transurethral device or cream, optionally with a vacuum device). Surgery follows only if that also fails.

Is a penile prosthesis reversible?

No. The implant permanently replaces the erectile tissue of the corpora cavernosa: after surgery, a return to drug therapy is no longer possible. This is why the decision is taken with the specialist, after a complete treatment pathway, and shared with the partner.
