    Erectile dysfunction is a major postoperative complication following radical prostatectomy. Various treatments for post- radical prostatectomy erectile dysfunction including nonsurgical phosphodiesterase-5 inhibitors, intraurethral alprostadil, intracavernosal injections and penile implant prosthesis, often yield suboptimal results. In this prospective single-center case series, we examine the efficacy and outcomes of Himplant®, a subcutaneous silicone penile implant, placement in four patients with post-radical prostatectomy erectile dysfunction who experienced limited benefits with phosphodiesterase-5 inhibitors. Patient data including demographics, prostate cancer diagnoses, erectile dysfunction characteristics, previous treatments, and outcomes were collected. Himplant® placement was performed in a standardized manner through a high scrotal incision in all cases. Follow-up evaluations were conducted to assess the effectiveness of the procedure and any associated complications. Patients were contacted and asked 15 questions regarding satisfaction and erectile function with the responses recorded. This study presents findings of high patient satisfaction, increases in flaccid penile length and girth, no incidence of adverse events, and improved erectile function following Himplant® placement post-radical prostatectomy. Accordingly, we suggest Himplant® placement in patients who are frustrated by their penile appearance and suffering from erectile dysfunction after radical prostatectomy. Further multicenter studies are warranted to validate these findings and assess long-term outcomes and patient-reported satisfaction.

    Over the years, numerous non-surgical and surgical treatment options have been explored for Peyronie’s disease. Current options may result in incomplete correction of the deformity, which can be bothersome to the patient. This is a two-center case series of three patients who had previously undergone treatment for Peyronie’s disease. Patient 1 underwent plication with extratunical grafting. Patient 2 underwent a series of Xiaflex® injections and then subsequent surgical plication for residual curvature. Patient 3 underwent a series of Xiaflex® injections. The Himplant® subcutaneous silicone penile prosthesis was placed in a standardized manner through a scrotal incision in all cases to mask residual penile deformities and enhance penile girth after Peyronie’s disease treatment. Patients were contacted and asked 18 questions regarding satisfaction and erectile function with the responses recorded. This pilot study presents findings of high patient satisfaction, increases in flaccid penile length and girth, and an acceptable profile of adverse events following Himplant® placement. Based on our limited experience, we would consider offering Himplant® implantation when residual curvature is <40° and the penile indentation does not cause instability/buckling during penetrative sexual activity. Further research and larger studies are warranted to validate these findings and assess long-term outcomes and patient-reported satisfaction.
