Comparison of efficacy and satisfaction profile, between penile prosthesis implantation and oral PDE5 inhibitor tadalafil therapy, in men with nerve-sparing radical prostatectomy erectile dysfunction
Abstract
UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Erectile dysfunction after nerve-sparing radical retropubic prostatectomy constitutes a challenge to the urologist. The mainstay of medical treatment after radical prostatectomy to restore spontaneous erectile function remains phosphodiesterase (PDE5) inhibitors, despite the fact that data from animal studies suggesting that PDE5 inhibitors can prevent smooth muscle apoptosis and fibrosis have not yet been extrapolated to humans because of a lack of standardized protocols. If the above treatment fails, second-line therapies such as intraurethral prostaglandins, penile injection therapy and vacuum devices are offered. When less invasive therapies are ineffective, interventions that preserve sexual function such as penile prosthesis implantation become the treatment of choice. Our study reveals the alternative of penile prosthesis implantation as first-line treatment in erectile dysfunction after nerve-sparing radical prostatectomy. It also highlights its superiority to the oral PDE5 inhibitor treatment, regarding the erection, frequency, firmness, maintenance and penetration ability. This suggests that a concept of an early penile intervention in the future would be promising for those patients who wish to remain sexually active without depending on oral formulations with doubtful and delayed results.
OBJECTIVE: To evaluate the outcome of penile prosthesis surgery in comparison to oral phosphodiesterase…
