Erectile impotence: evaluation and management

Area of Science:

• Urology
• Andrology
• Men's Health

Background:

• Erectile dysfunction (impotence) has seen dramatic progress in understanding and treatment over the last decade.
• Most cases of erectile dysfunction have an organic cause linked to vascular supply, penile innervation, or hormonal factors.
• Common multifactorial causes include diabetes mellitus, alcoholism, renal failure, and liver failure, with medications also contributing through various mechanisms.

Purpose of the Study:

• To review the current understanding and treatment options for erectile dysfunction.
• To highlight the diagnostic role of history, physical examination, and basic laboratory tests.
• To present recent advancements in both nonsurgical and surgical treatment modalities.

Main Methods:

• Review of recent literature on erectile dysfunction.
• Emphasis on clinical evaluation including history, physical examination, and laboratory testing.
• Description of current therapeutic interventions, including pharmacological, mechanical, and surgical options.

Main Results:

• Nonsurgical treatments like penile self-injection (papaverine, phentolamine) and suction devices are effective.
• Penile prostheses have seen significant improvements, with options including semirigid, multicomponent inflatable, and self-contained inflatable devices.
• New surgical treatments include penile arterial revascularization for atherosclerosis and dorsal vein ligation for venous leak.

Conclusions:

• Erectile dysfunction is often organic and multifactorial, requiring a thorough diagnostic approach.
• A range of effective nonsurgical and surgical treatments are available, significantly improving patient outcomes.
• Family physicians can play a key role in the initial evaluation and management of erectile dysfunction.
