Erectile Dysfunction Treatment

Introduction to Treatment Options

PDE5 inhibitors are the first-line treatment for erectile dysfunction after radiation therapy or radical prostatectomy, with tadalafil 5-20mg, sildenafil 50-100mg, or vardenafil 10-20mg being the recommended options, according to the American Urological Association and American Cancer Society 1, 2

Multiple trials (at least 4-6 attempts) may be necessary before establishing efficacy of PDE5 inhibitors, and dose titration is often necessary for optimal results, as suggested by the American Urological Association 2
Younger patients (<55 years) have better response rates to PDE5 inhibitors, and preservation of neurovascular bundles significantly improves response to PDE5 inhibitors, as noted by the American Urological Association 2
Patients with partial erectile function respond better to PDE5 inhibitors than those with complete ED, as observed in clinical studies 2

Key counseling points for PDE5 inhibitors include the need for sexual stimulation for medication effectiveness, multiple trials may be required before establishing efficacy, and dose titration is often necessary for optimal results, as recommended by the American Urological Association 2
Early use of PDE5 inhibitors (penile rehabilitation) may improve long-term outcomes, and penile rehabilitation should begin early after surgery to preserve tissue health and improve long-term outcomes 1, 2

Vacuum erection devices are a non-invasive option that creates negative pressure to draw blood into the penis, with common side effects including penile bruising, discomfort, and difficulty with ejaculation, and caution is advised in patients on anticoagulants or with bleeding disorders 2
Intraurethral alprostadil involves inserting a prostaglandin E1 pellet into the urethra, with success rates ranging from 29.5% to 78.1%, and requires in-office test dose before prescribing for home use 2
Combining therapies, such as PDE5 inhibitors with vacuum devices, or testosterone therapy with PDE5 inhibitors in men with low testosterone, may improve results, as noted by the American Urological Association 2

Men with ED and testosterone deficiency should be informed that PDE5 inhibitors may be more effective when combined with testosterone therapy, but testosterone therapy alone is not effective for ED, as recommended by the American Urological Association 2
Important discussion points include the fact that ED affects up to 50% of men after radiation therapy, and most men after radical prostatectomy, with recovery depending on age, nerve-sparing technique, and baseline function 1, 3
Partners should be included in discussions about sexual recovery, and regular assessment of treatment efficacy, willingness to try different options if initial treatment fails, and psychological support for both patient and partner are essential, as suggested by the American Cancer Society 1
Consider referral to a urologist or sexual health specialist for patients who fail PDE5 inhibitor therapy, as recommended by the American Cancer Society 1
