Organic Aetiology of ED

We now understand that the aetiology of ED is primarily organic in the majority of individuals

The psychological aspects manifest themselves subsequently because the negative emotional effects of ED are so wide-ranging and devastating

Focus on the penis alone has evolved to focus on the value of achieving a dependable, hard erection that is the catalyst to the emotional benefits associated with sex in a relationship

Case-Finding and Work-Up for ED

Health care practitioner comfort with male sexual dysfunction

Positive impact on Men's Health Care and on Quality of Life

Simple, straight-forward approach (ask or questionnaire)

Tests - keep things simple - lipids, blood sugar, BP, smoking, diabetes, and obesity

Focused physical examination

Identify anxiety, depression, partner-issues

Treatment Success = Monitor Treatment

Is there a cardiac effect for PDE-5 inhibitors?

Peyronie’s Disease

• Acquired penile deformity secondary to scarring of the tunica albuginea

• Cause penile deformity (curve, hourglass, cork-screw, combination)

• Often accompanied by pain (acute phase)

• Associated with erectile dysfunction

Peyronie’s Disease: Defining the Problem

• Remains a therapeutic dilemma

• Physically and psychologically debilitating

• Approximately 4% of men

Normal Tunica Peyronie’s Disease

Ultrastructural Changes: Scanning EM

• Cohort data suggests prevalence 4-9%, dependent on age distribution

• Cohort data suggests prevalence 4-9%, dependent on age distribution

• 12% spontaneous improvement, 40% stable, 48% worsening

• Cluster 50-55 years of age

• Cluster 50-55 years of age

• Men less than 40 - multiple plaques, more significant deviation

• Nearly 1/2 of men have clinically meaningful depression, and 80-90% have psychological manifestations

PEYRONIE’S DISEASE: EVALUATION

• History - degree, duration, EF

• No disease-specific questionnaire

• Physical examination include SPL

• Position, number, size

• ICI erection, high-resolution US, calipers

PENTOXIFYLLINE - SHOW ME THE PROOF?


• Decrease TGF-1, increase cAMP, decrease collagen 1 production



• Decrease size of plaques (rat model)




• Case reports - decrease corporal fibrosis post-priapism, decrease calcifications in PD




• Case reports - decrease corporal fibrosis post-priapism, decrease calcifications in PD

• Double-blind placebo controlled trial shows benefit in early Peyronie's disease

INTRALESIONAL THERAPY




• Likely not 50% response rate as previously projected

PENILE TRACTION THERAPY

SURGICAL MANAGEMENT OF PEYRONIE'S DISEASE: PLICATION PROCEDURES

WHEN IS PENILE PLICATION AN OPTION FOR PEYRONIE'S DISEASE?

• Patient selection for any surgical approach for Peyronie'sdisease is paramount



• Stable curvature, limits sexual function (<60 degrees and uniplanar are not absolute requirements)



• Stable curvature, limits sexual function

• Maintained erectile function

• Sufficient penile length

TYPES OF PENILE PLICATION SURGERY

Tunical Manipulation

• Classic Nesbit's/wedge repair

• Plication with partial thickness shaving of the tunica

TYPES OF PENILE PLICATION SURGERY

Tunical Manipulation

• Classic Nesbit's/wedge repair

• Plication with partial thickness shaving of the tunica

Non- or Minimally Disruptive to the Tunica

• Plication without tunical incision

• Minimal-tension (Lue 16-dot) technique

LUE 16-DOT TECHNIQUE












DRAWBACKS AND LIMITATIONS

Does not allow for recovery of Peyronie's length loss

Penile shortening

Requires satisfactory erectile function


Does not allow for recovery of Peyronie's length loss

May contribute to further penile shortening

Requires satisfactory erectile function


Does not address hinge, hourglass or notching deformity

May result in penile pain, palpable knots, sensation changes (NVB mobilization)

Incomplete correction or recurrence

May contribute to erectile dysfunction

What is the effect does low testosterone have on ED?

25-33% of men who fail a PDE5 inhibitor will be hypogonadalIf hypogonadal, replacing T alone usually does not restore erectionCombination therapy with T and PDE5 inhibitor
