Rigi10™ Malleable Penile Prosthesis
Detailed Answer
Penile prosthesis implantation is a viable treatment for men experiencing erectile dysfunction (ED), especially when other therapies fail. According to the 2025 EAU Guidelines, candidates are men who are not suitable for different pharmacotherapies or prefer a definitive therapy, and do not respond to other treatment modalities. This includes patients who do not benefit from oral PDE5 inhibitors (e.g., sildenafil), intracavernosal injections, or vacuum erection devices.
Typical candidates include those with advanced diabetes mellitus, post-prostatectomy ED, spinal cord injuries, or Peyronie’s disease with significant penile deformity. In cases of ischemic priapism, immediate or delayed implantation may also be considered to restore sexual function.
The decision to proceed with implantation involves shared decision-making between the patient and the urologist, including a thorough review of expectations, surgical risks, and postoperative care. Psychological counseling may also be beneficial to align patient and partner expectations.
There are two primary types of implants: inflatable (two- or three-piece) and malleable (semi-rigid) prostheses. The choice depends on the patient’s physical condition, manual dexterity, and personal preference. While inflatable types offer a more “natural” erection and better concealment, malleable implants are simpler to use and may be preferable in patients with limited mobility or dexterity.
Success and satisfaction rates for penile implants are high. Studies report patient satisfaction between 92-100%, with comparable rates (91-95%) in partners. The surgical outcomes are durable, and with proper technique and device selection, infection rates remain under 2-3% in primary cases.
It’s crucial that men considering this treatment understand that while implants restore rigidity, they do not affect penile sensitivity, ejaculation, or orgasm. Most men are able to resume sexual activity within 4-8 weeks post-surgery after proper healing and instruction.
From the Guidelines
