Inflatable penile prosthesis reservoir placement—Are we ready for a paradigm change? / Colocación de reservorio para prótesis de pene inflables: ¿estamos preparados para un cambio de paradigma?

In 2002, Steve Wilson pioneered new procedures for alternative placement of reservoirs for inflatable prostheses in patients who have suffered damage to the space of Retzius following pelvic surgery or obliteration of the transversalis fascia by mesh hernia repair. Since then, surgical techniques and tools for ectopic reservoir placement have gradually gained acceptance to minimize palpability, and the risk of visceral and vascular lesions for high risk patients has been all but eliminated. Lockout valves and high submuscular placement techniques are now recommended, and reports of vascular, bowel or bladder injuries are uncommonly rare. While surgeons continue their search for safer and more effective placement methods, new skills and instruments are constantly being introduced to make recommendations to minimize complications and provide safety and functionality. Additional studies and comparisons of techniques are needed to achieve a consensus of best practice for reservoir placement solutions. (AU)

En 2002, Steve Wilson fue el precursor de nuevos procedimientos para la colocación alternativa de reservorios para prótesis inflables en los pacientes que habían sufrido daños en el espacio de Retzius tras cirugía pélvica u obliteración de la fascia transversalis por reparación de hernia con malla. Desde entonces, han ido ganando aceptación las técnicas y herramientas quirúrgicas para colocación de reservorio ectópico, a fin de minimizar la palpabilidad, habiéndose eliminado prácticamente el riesgo de lesiones viscerales y vasculares para pacientes de alto riesgo. Hoy en día se recomiendan las válvulas de bloqueo y las técnicas de colocación submuscular alta, siendo excepcionalmente raros los informes sobre lesiones a nivel vascular, intestinal o en la vejiga. A pesar de que los cirujanos siguen investigando en busca de métodos de colocación más seguros y efectivos, se están introduciendo constantemente nuevas competencias e instrumentos en aras de realizar recomendaciones para minimizar las complicaciones y aportar seguridad y funcionalidad. Son necesarios más estudios y comparaciones sobre técnicas para lograr un consenso acerca de la mejor práctica sobre soluciones de colocación de reservorios. (AU)

Technological Improvements in Three-Piece Inflatable Penile Prosthesis Design over the Past 40 Years.

INTRODUCTION: The advent of the penile prosthesis revolutionized the treatment of erectile dysfunction (ED), resulting in near-complete treatment efficacy and high patient satisfaction rates. While several types of penile prosthesis are available, the inflatable penile prosthesis (IPP) is the most commonly used device in the United States. AIMS: To describe the key modifications to IPPs from the two major manufacturers-American Medical Systems (AMS) and Coloplast-since the invention of the IPP, and to relate these changes to improvements in prosthesis function and patient outcomes based on available literature. METHODS: Review and evaluation of the literature between 1973 and present describing modifications in IPP design and the influence of these modifications on IPP durability and patient-related factors. MAIN OUTCOME MEASURES: Data describing the impact of iterative improvements in three-piece IPP design on device function, durability, and patient outcomes. RESULTS: There were progressive improvements in IPP technology from both major manufacturers not only on the durability of the prosthesis but also on patient outcomes, with fewer device failures and lower infection rates. Notable improvements include incorporation of kink-resistant tubing, changes in the weave or addition of shear- and infection-resistant coatings to cylinder layers, pump and tubing connection modifications, the addition of rear tip extenders, and the incorporation of lockout valves to prevent autoinflation. CONCLUSIONS: Numerous incremental modifications to the IPP from both major manufacturers since its invention have increased its durability and improved patient outcomes.
