New Advancements in Inflatable Penile Prosthesis

Inflatable penile prosthesis (IPP) technology is a mainstay in the treatment of erectile dysfunction refractory to medical management. Technological advancements in the design of 3-piece IPPs have been improved to optimize concealability and surgical placement since the 1980s. Recent advancements over the past 10 years include pump, reservoir, tubing, and cylinder updates.

This review examines the latest updates in IPP technology, reviews recent relevant research, and is based on over 32 years of experience performing IPP surgery in addition to concurrent postoperative management.

A literature review was conducted for studies published over the last 10 years through March 2020 with an emphasis on technical updates of IPP, specifically the pump, reservoir, tubing, and cylinder, and their functional outcomes. Anti-infective coating and transgender innovations, in addition to postoperative management, are also reviewed.

Technological advancements include a flat reservoir designed for improved discreteness and a prosthesis with optimized tubing length, a one-touch deflatable 3-piece system, narrow-base cylinders, a 0° angle design between the cylinders and tubing to aid in cylinder placement, a soft molding cylinder tip redesign that better mimics human anatomy, and a 3-piece IPP specifically designed for neophallus use. Furthermore, the Food and Drug Administration approved the submuscular reservoir placement.

Penile prosthesis has evolved over time to improve functional outcomes, ease of use, and minimize postoperative complications and pain. Penile prosthesis implantation continues to be a life-changing procedure for patients and it is imperative for surgeons to be up-to-date on the latest developments and research in order to provide the best functional outcomes for those they take care of.
