Abstract
ABSTRACT Penile prosthesis surgery is a definitive treatment for erectile dysfunction (ED). The two categories of penile prosthesis are endorsed by professional guidelines, inflatable penile prosthesis (IPP) and malleable penile prosthesis (MPP). Each modality of penile prosthesis offers distinct advantages and incorporates specific design features, allowing for personalized device selection that aligns with individual needs and preferences. While the overall complication rate of penile implant surgery remains low, surgeons should maintain a high index of suspicion for complications in the perioperative time period. Multimodal analgesic regimens including nerve blocks and narcotic-free pathways should be administered to manage perioperative pain. Finally, the high patient satisfaction after penile prosthesis surgery underscores the success of this ED treatment option.

Abstract
Background and Objective In contemporary Urology, the gold standard for treatment of erectile dysfunction refractory to medical therapy has been implantation with a penile prosthesis. The past 40 years has witnessed evolutions in technology and surgical techniques, which have led to increased patient satisfaction rates and decreased complication and infection rates. This review is an update to a prior review article that evaluates these advancements in the context of patient satisfaction and different rates of complications following surgeries. In addition, the review compares malleable and inflatable prostheses with regard to infection rate, mechanical failure rate, and erosion rate. Methods A literature search was conducted using Medline and Google Scholar to examine papers from 1973 to the present day. Keywords, such as, "penile prosthesis surgery", "malleable penile prosthesis", "inflatable penile prosthesis", "two-piece Inflatable Penile Prosthesis (IPP)", and "three-piece IPP" were utilized during the search. A total of 76 papers were included, and all were in English. Key Content and Findings Studies on the latest models of each of the three prostheses (malleable, two-piece IPP, three-piece IPP) revealed patient satisfaction ratings at or above 75%. Both types of IPPs were associated with greater satisfaction and lower erosion rates while malleable prostheses were associated with lower mechanical failure rates. Although no significant differences in infection rates were noted between the prosthesis types, a history of diabetes, obesity, and smoking were predictive of infection events. Conclusions The three-piece IPP, if indicated for a suitable patient, is generally accepted as the best type of prosthesis given its biological mimicry to an erect human penis.

Abstract
Penile implant surgery is the gold standard to treat erectile dysfunction with success rates of over 90%. The first penile implants were developed in the early 1900s. Since then, several types of implants have been developed including malleable implants, two-piece inflatable implants, and three-piece inflatable implants. The three-piece inflatable penile prosthesis, which was introduced in 1973, is the most widely used type of penile implant in the United States. Penile implant surgery has undergone numerous advancements over the years, improving outcomes and patient satisfaction. However, as with any surgical procedure, there are risks and complications associated with penile implant surgery. It is important for surgeons to understand these potential complications and to have strategies in place to manage and prevent them to achieve the best possible outcomes for their patients.

Abstract
Penile prostheses are implantable devices used to definitively treat erectile dysfunction when previous forms of treatment have failed. The first example of a penile implant dates to 1935, when a rib was inserted in a neo-phallus reconstructed after a traumatic amputation. Since then, alternative artificial devices were adopted as penile prosthetic implants. The evolution of prosthetic devices had a dramatic thrust in 1973 when the first inflatable penile prosthesis was worldwide presented. Thanks to advances in device materials, design, surgical implant techniques, and perioperative management, nowadays inflatable penile prostheses are one of the most adopted definitive therapy for patients with drug-refractory erectile dysfunction or refusing alternative forms of treatments. Moreover, the clinical indications for inflatable penile prosthesis have also expanded, including female-to-male transmen or men underwent penile reconstruction due to congenital aphallia or traumatic or surgical penile amputation. In order to summarise the process behind the development and evolution of penile prosthesis, we aimed at performing a historical review of the currently available literature to provide an easy and comprehensive overview of the topic. The understanding of the historical process behind the evolution of inflatable penile prostheses will drive further innovation to increase efficiency and the rate of patients satisfaction.

Abstract
INTRODUCTION The artificial urinary sphincter and 3-piece inflatable penile prosthesis each require a fluid storage component and thus have components in the inguinal and pelvic regions. Because of this, patients with urologic prosthetics sometimes present challenges during future nonprosthetic operations. Presently, there is no established guideline for device management with ensuing inguinal or pelvic surgery. AIMS This article outlines concerns during pelvic and inguinal surgery for patients with an artificial urinary sphincter and/or inflatable penile prosthesis and proposes an algorithm for preoperative surgical planning and decision making. METHODS We conducted a narrative review of the literature on operative management of these prosthetic devices. Publications were identified by searching electronic databases. Only peer-reviewed publications available in English were considered for this review. RESULTS We review the important considerations as well as available options for operative management of these prosthetic devices during subsequent nonprosthetic surgery and highlight the advantages and disadvantages of each. Finally, we suggest a framework for helping surgeons determine which management strategy is most appropriate for their individual patients. CONCLUSION The best management strategy will differ depending on patient values, the planned surgery, and patient-specific factors. Surgeons should understand and counsel patients on all available options and encourage informed, shared decision making to determine the best individualized approach.

A pilot study of inflatable penile prosthesis placement in transgender neophallus using Tutoplast ® pericardium graft sock technique. Transl Androl Urol 2023; 12:1326-1335. [PMID: 37680230 PMCID: PMC10481199 DOI: 10.21037/tau-22-837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 06/13/2023] [Indexed: 09/09/2023] Open
Abstract
Placement of an inflatable penile prosthesis (IPP) in a transgender patient's neophallus carries unique considerations versus cis-gender IPP placement in mitigating infection, erosion, and overall complication rates. An example of this includes the lack of an anatomical corpus cavernosum and crura for cylinder placement and anchoring. Multiple grafting approaches and materials have been utilized to mitigate possible cylinder instability and improve anchoring. Here we describe our experience and surgical technique in IPP neophallus placement utilizing a single cylinder with distal and proximal cylinder human cadaver pericardium (Tutoplast®, IOP Ophthalmics, Costa Mesa, CA, USA) grafts. Our goals were to determine postoperative satisfaction and device functionality in patients undergoing transgender neophallus IPP placement using our technique. Both patients report satisfaction and no complications at last follow-up (currently up to 14 and 23 months post-operatively, respectively) with satisfactory erectile function and ability to perform penetrative intercourse. In neophallus IPP placement, the anatomical differences compared to cis-gender IPP operations require unique considerations such as cylinder grafting material selection for proximal cylinder fixation and mitigation of device erosion rates. Optimization of grafting material in neophallus IPP placement in an effort to reduce erosion rates has become increasingly important as frequency of this operation increases. Utilizing human cadaver pericardium graft in distal and proximal cylinder coverage shows beneficial preliminary outcomes in our patients.

Abstract
UNLABELLED Sensory nerve transfers are performed as part of phalloplasty surgery. Despite this, sensory re-education to rehabilitate these nerve transfers has not been employed. Additionally, little attention has been paid to the role of the central nervous system in experienced sensation following phalloplasty. The purpose of this article is to report on the development of a targeted rehabilitation protocol to integrate and optimize peripheral and central contributions to sensation following phalloplasty. METHODS This neurosensory re-education protocol was constructed over four phases by a multi-disciplinary team (phalloplasty/peripheral nerve surgeon, reconstructive urologist, pelvic floor physiotherapists, nerve therapist, sex therapist, sexual medicine physician) and individuals with lived phalloplasty experience. The final protocol was approved by all team members and is supported here by qualitative narratives from people with lived phalloplasty experience. RESULTS The protocol is built to follow each stage of phalloplasty surgery. In each stage, exercises are grouped into three core themes: visualization, tactile stimulation, and sexual/erogenous stimulation. Visualization exercises progress from static to dynamic. Tactile exercises start at simple touch and progress toward targeted sensory stimulation. Sexual stimulation focuses on developing erogenous sensation in the phallus that is separate from erogenous sensation in the natal clitoral tissue. By recommendation of individuals with phalloplasty, the protocol is now integrated into our center's phalloplasty care pathway for all individuals undergoing phalloplasty surgery. CONCLUSION We introduce a novel protocol targeting peripheral and central contributions to sensation to provide a tool to help optimize experienced sensation for transmasculine individuals undergoing phalloplasty.

Abstract
Erectile dysfunction (ED) is a common problem, and prevalence rates are expected to rise as life expectancy increases worldwide. In more severe cases of ED, penile prosthesis implantation has been an excellent option for patients. Over the past few decades, significant design improvements have been made to the penile prosthesis and modifications to surgical technique to improve clinical outcomes. The purpose of this review is to summarize the safety and efficacy of FDA-approved penile implants in the US market. Design modifications have greatly improved the safety and reliability of the implant. Development of improved surgical techniques has decreased intraoperative injuries and reservoir-related complications. With its high overall satisfaction rates and low risk of complications, the inflatable penile prosthesis remains an excellent option for patients with erectile dysfunction.
