Discussion/General Information

The American Urological Association (AUA) 2018 erectile dysfunction (ED) guideline defines ED as “…the consistent or recurrent inability to attain and/or maintain penile erection sufficient for sexual satisfaction, including satisfactory sexual performance.”

According to the AUA guideline, independent risk factors for ED are similar to those for cardiovascular disease. These include, among others, smoking, diabetes mellitus, hypertension, dyslipidemia and obesity. Between 20% and 85% of men with diabetes, and approximately 35% of men with dyslipidemia, experience ED (AUA, 2018). Moreover, approximately 75% of men with heart failure experience ED, and causes of ED in men with heart failure include arterial insufficiency, endothelial dysfunction, reduced cardiac capacity and side effects of medication for cardiovascular disease (Rastogi, 2005). In addition, surgery (especially radical prostate and bladder surgery for cancer) and radiotherapy can injure nerves and arteries near the penis, causing ED (Chung, 2014).Injury to the penis, spinal cord, prostate, bladder, and pelvis can lead to ED by harming nerves, smooth muscles, arteries, and fibrous tissues of the corpora cavernosa.

Penile prosthesis implantation is a treatment option for men with ED who have failed less invasive treatments. For those without other comorbidities, oral phosphodiesterase-5 (PDE5) inhibitors such as sildenafil and tadalafil are usually first-line therapies, unless contraindicated. Recent meta-analyses have found that all available oral PDE5 inhibitors are effective, compared with placebo, with similar efficacy of the various PDE5 inhibitors (Allen, 2019). For men with testosterone deficiency, PDE5 inhibitors can be supplemented with testosterone therapy (AUA, 2018). If oral medications are not sufficient, a vacuum device, which is a noninvasive modality, is often recommended before a penile prosthesis. Underlying causes for erectile dysfunction are important to identify and address, if possible, with appropriate interventions.

The U.S. Food and Drug Administration (FDA) considers the rigid penile implant as a Class II device. The semi-rigid rods are implanted into the corpora cavernosa of the penis to provide rigidity. Inflatable penile implants are considered Class III devices by the FDA. Inflatable cylinders are implanted in the penis and are connected to a reservoir filled with fluid implanted in the abdomen, and a subcutaneous manual pump implanted in the scrotum. Penile rigidity is achieved when the cylinders are filled with fluid.

In 2018, the AUA published an updated guideline on ED. Recommendations in this guideline that are specific to penile prosthesis implantation are as follows:

Men with ED should be informed regarding the treatment option of penile prosthesis implantation, including discussion of benefits and risks/burdens. (Strong Recommendation; Evidence Level: Grade C)

Men with ED who have decided on penile implantation surgery should be counseled regarding post-operative expectations. (Clinical Principle)

Penile prosthetic surgery should not be performed in the presence of systemic, cutaneous, or urinary tract infection. (Clinical Principle)

The guideline stated, “the potential risks and burdens of prosthesis surgery include the risks inherent in the surgical procedure, possible changes in the appearance of the penis, and the potential for device malfunction or failure”.

Penile prostheses have primarily been evaluated in uncontrolled case series. For example, Zermann and colleagues (2006) studied penile implant efficacy in 245 neurologically impaired men. Men were categorized into 3 groups based on the indication for penile prosthetic surgery. Group 1 consisted of 134 participants with urinary management only, Group 2 had 60 participants with erectile dysfunction only, and Group 3 had 51 participants with urinary management and erectile dysfunction. At a mean follow-up of 7.2 years (maximum 17 years), 195 participants were reevaluated in the clinic. Outcomes showed that in 122 participants (90.3%) urinary management problems were resolved, and erectile dysfunction treatment was successful in 76 participants (82.6%). A total of 43 revisions were performed for complications (e.g., infections and device perforation).

Sevinc and colleagues (2017) evaluated outcomes after penile prosthesis implantation in 181 men with ED of different etiologies. Primary causes of ED were diabetes in 81 men (44.7%), vascular disease in 45 men (25.4%), radical pelvic surgery in 29 men (16%) and a variety of other reasons in the remaining 25 men (13.8%). The most common post-operative complications were superficial wound infection (n=17, 9.4%), dehiscence of the glans penis (n=10, 5.5%), which resolved after 1 month, and pain during intercourse (n=10, 5.5%), which resolved within a few months. The mean time to first intercourse was 54 days (range: 9 to 150 days). Individuals were followed for at least 12 months. At follow-up, 104 individuals (57.5%) reported being very satisfied with the penile prosthesis, 48 (26.5%) were satisfied and 21 (11.6%) were not satisfied. A total of 21 prostheses (11.6%) were removed because of complications or patient dissatisfaction.

Khera and colleagues (2018) reported data from an industry-sponsored registry of individuals who were implanted with American Medical Systems (AMS) penile implants. A total of 1180 individuals with ED were included in the registry. Of these, 250 individuals (21.2%) had Peyronie’s disease (PD). At 1- and 2-year follow-ups, 88.6% and 88.5%, respectively, of individuals with PD stated that they were either satisfied or very satisfied with treatment. The rate of self-reported depression in individuals with PD decreased from 19.3% at baseline to 10.5% at the 1-year follow-up (p=0.02).

In terms of complication rates, Minervini and colleagues (2006) studied 447 men who had 504 penile prosthetics implanted and found that infection was the most frequent complication. Other complications were implant migration and tissue erosion. In a review by Phe (2012), the rate of infection decreased to 1% with the utilization of antibiotic impregnated implants. In a report on 98 men in a national database who had penile prosthesis implantation between 2005 and 2013 (Palma-Zamora, 2017), the overall 30-day complication rate was 11% (n=11). The complications included surgical site infection (n=6), transfusion (n=3), urinary tract infection (n=1) and sepsis/shock (n=1).

Carvajal and colleagues (2020) published a systematic review of studies on factors associated with infection in individuals with penile prostheses. They included 40 studies with a total of 175,592 individuals. Fifteen studies focused on diabetes mellitus which was found in pooled analyses to be significantly associated with risk of infection (odds ratio [OR], 2.48; 95% confidence interval [CI], 1.38 to 4.47). Other factors significantly increasing risk of infection in individuals with penile prostheses were immunosuppression (3 studies, OR, 20.99; 95% CI, 0.71 to 622.34) and obesity (2 studies, OR, 18.24; 95% CI, 1.43 to 231.98). However, other than in the analysis on diabetes mellitus, numbers of studies and total sample sizes were small and thus estimates of increased risk were imprecise as indicated by wide confidence intervals. 

A 2020 systematic review by Dick and colleagues identified 14 studies reporting on outcomes after penile prosthesis implantation in individuals with solid organ transplant. Most of the studies were case reports or case series but there were also 2 retrospective cohort studies. Overall, the studies included 143 individuals with solid organ transplant and 191 controls without solid organ transplant, all of whom received penile prostheses. In a pooled analysis, the authors did not find a significant difference in the prosthetic infection rate among individuals with solid organ transplant (2.1%) and controls (3.7%), p=0.53. They also did not find a statistically significant difference in the rate of non-infective complications in individuals with solid organ transplant (9.8%) versus controls (4.7%), p=0.08. A limitation of the literature on this topic is that most studies were small and uncontrolled, and all were retrospective.
