Abstract
BACKGROUND During the last century, surgical management of erectile dysfunction has evolved from an experimental concept to a core treatment modality with widespread use among the men's health community. Over time, innovations in materials, mechanical design elements, device coatings, and surgical technique have provided patients with low-risk, reliable, and reproducible erectile function with high satisfaction rates. AIM To provide a foundation for future innovation by improving understanding of historical penile prosthetics and the rationale behind incremental technological improvements for the contemporary Men's Health physician. METHODS Literature review was conducted to generate a comprehensive review of historical technological innovations in penile implant surgery. Companies with FDA approved penile prosthetics in use in the United States were contacted for information regarding technological innovations in the past and future devices in development. A separate literature review was performed to identify any significant future device design elements being tested, even in the ex vivo setting, which may have future clinical applications. OUTCOMES Technological innovations in penile implant surgery were described. RESULTS Current options for the prosthetic surgeon include malleable penile prostheses (MPP), self-contained (2-piece) inflatable penile prostheses, and multicomponent (3-piece) inflatable penile prostheses. Current MPPs consist of a synthetic coated solid core which allow for manipulation of the penis for concealability while maintaining sufficient axial rigidity to achieve penetration when desired. Multi-component (3-Piece) IPPs currently include the Coloplast Titan and Boston Scientific/AMS 700 which consist of a fluid reservoir, intrascrotal pump, and intracavernosal cylinders. The devices have undergone numerous design updates to the cylinders, pump, reservoir, tubing, and external coatings to increase reliability and decrease short- and long-term complications. CLINICAL IMPLICATIONS Future innovations in penile prosthetic surgery seek to broaden the indications and applicability to the transgender community and improve both safety and functionality for patient and partner. STRENGTHS & LIMITATIONS The review is limited primarily to penile prosthetics approved for current or historical clinical use in the United States and may not be representative of the global prosthetic environment. Additionally, the research and development of future innovations, particularly those provided by device manufacturers, is likely limited by non-disclosure to maintain a competitive advantage. CONCLUSIONS Penile prosthetic surgery will undoubtedly remain integral to the treatment of erectile dysfunction, and education regarding the current state of technological innovation will empower the prosthetic surgeon and biomedical engineering community to improve contemporary patient care and drive the development of the next generation of implantable penile prosthetics.

Abstract
During the first 5 years after penile prosthesis implantation, complications such as malfunction requiring revision or replacement occur in only 7% of cases. We present a case of a 62-year-old patient who had a Coloplast Titan® prosthesis implanted while also undergoing girth enhancement corporoplasty. Shortly after, the patient noticed an increasing bulge on the side of his penis, which prevented total deflation. An aneurysm of the right cylinder was identified during reoperation; cylinders were replaced and the redundant tunica albuginea and septal defect were corrected by plication from inside the corpora cavernosa.

Abstract
PURPOSE OF REVIEW The goal of this paper was to evaluate the current use of semirigid penile prosthesis (SRPP), surgical techniques for insertion of SRPP, and how to prevent and approach surgical complications. RECENT FINDINGS SRPP is a valid option for those who are refractory to medical therapy for erectile dysfunction (ED) and even more appropriate for specific subsets of patient populations. It is important for urologists to know which patient population SRPP is preferred for. Several studies have shown good patient outcomes and patient satisfaction with those who underwent SRPP.

Abstract
INTRODUCTION Inflatable penile prosthesis (IPP) is an established treatment option for men with erectile dysfunction (ED) refractory to medical therapy. Standardization of surgical technique and improvements in device construction have reduced all-cause complication rates to less than 5% in recent reports. Nonetheless, complications do exist, and can strongly impact morbidity and the quality of life of patients. Prosthetic urologists must be aware of the constellation of complications that can arise during or after IPP placement. AIM To provide a comprehensive review of penile prosthesis complications and discuss preventative strategies, as well as proper preoperative, intraoperative, and postoperative decision making. METHODS A review of the available literature from 1973 to 2018 was performed using PubMed with regard to IPP complications. MAIN OUTCOME MEASURES We reviewed publications that outlined preoperative planning strategies and the following IPP complications: hematoma, floppy glans, corporal fibrosis, corporal perforation and crossover, urethral injury, infection, impending erosion, and glandular ischemia. RESULTS Careful patient and device selection, setting realistic expectations of postsurgical outcomes, and adherence to a perioperative checklist is essential in the preoperative period. Intraoperatively, anticipate corporal fibrosis situations and always dilate laterally during corporal passage to reduce the risk of crossover and urethral injury. Limit perioperative antiplatelet therapy, apply compressive dressing, use a closed suction drain if indicated, and leave the device partially inflated postoperatively to reduce risk of hematoma. After surgery, monitor patients for potential complications that may warrant device explantation or salvage: IPP infection, glans ischemia, and impending erosion. CONCLUSIONS By using evidence and expert opinion-based decision-making strategies in the preoperative, intraoperative, and postoperative period of IPP placement, surgeons can reduce the risk of complications and dissatisfaction, even in ED patients with multiple comorbid conditions.

Abstract
The inflatable penile prosthesis (IPP) is the gold standard surgical treatment for medical refractory erectile dysfunction (ED). While the modern IPP has enjoyed high satisfaction rates as a product of its continued innovation, reliability, and performance, patient dissatisfaction can still occur. IPP implantation restores physiologic function with cosmetic and psychological consequences, both of which place inherent emphasis on preoperative counseling and expectation management. This review aims to highlight the complex nature of such counseling and provide practitioners with a roadmap to navigate the landscape. Preoperative counseling begins with appropriate patient selection and identification of those patients who are at risk for dissatisfaction as a result of personality characteristics. The informed consent provides a natural framework to discuss the host of complications and risks that are associated with surgery, including infection, device malfunction, damage to nearby structures, and device erosion. Device selection is a nuanced process that merges patient preference with clinical factors and consideration. We address device selection through a description of cylinder construction, pump design, and reservoir placement in the context of preoperative counseling. Lastly, we draw attention to expectation management with a specific focus on possible post-operative changes to penile length and sensation as well as partner involvement. The modern IPP provides excellent results with high patient and partner satisfaction. Ultimately, satisfaction is dependent on multiple factors, but providing accurate, realistic counseling and expectation management prepares patients for the best possible outcomes.

Abstract
Genitourinary prosthetics are used for correction of functional deficits and to improve the quality of lives of affected patients. General surgeons must evaluate patients scheduled for nonurologic surgery with urologic devices that can impact their perioperative management. Lack of recognition of these prosthetics preoperatively can lead to unnecessary morbidity for the patient and have legal implications for the surgeon. Close consultation with a urologist may avoid common complications associated with these devices and allows for surgical assistance when operative misadventures do occur. This article reviews 3 common urologic prosthetics: testicular prosthesis, artificial urinary sphincter, and penile prosthesis.

Abstract
INTRODUCTION Traditionally, penile implant (PI) infections have been managed by removal with immediate or delayed replacement. Recently, interest has been focused on conservative therapy (CT) using antibiotic therapy. AIM To investigate the success rate and predictive factors affecting the outcome of CT in PI infection patients. METHODS Patients diagnosed with early, localized PI infection were considered candidates for CT. Exclusion criteria included temperature >37.5°C, WBC >13,000/μL, and appearance of any sign of sepsis. In patients with purulent drainage, culture swabs were taken and an antibiotic was chosen based on sensitivity results. Oral antibiotics were used until the local infection was completely resolved. Patients were evaluated weekly during this process. RESULTS Thirty-seven patients were retrospectively reviewed and constituted the study population. Mean age was 58.1 (range 37-85; SD 9.9) years. All were diabetic. Mean BMI was 31.8 (range 24-47; SD 5.0). PI was malleable in 33 cases and inflatable in 4 cases. Culture results (n = 19) included Staphylococcus epidermidis (42 %), pseudomonas (21%), Escherichia coli (21%), and S aureus (16%). Four of 37 patients needed the PI removed due to CT failure and onset of systemic symptoms, at a mean time-point of 75 ± 1.8 days after CT commencement. In men who were cured, mean time to complete healing was 49 (range 29-97; SD 15.8) days. Two of 37 patients (5%) had PI removal because of persistent penile pain despite complete wound healing, at a mean time point of 128 ± 2.5 days after CT commencement. All men managed conservatively resumed sexual intercourse. CONCLUSION CT of localized PI infection appears to be a viable option for such patients, with the majority of patients retaining their implant and resuming sexual activity.

Abstract
Objective To present our 3-year experience with the Egydio’s geometrical procedure for managing penile curvature with some modifications. Patients and methods In all, 330 patients (mean age 51 years) that underwent the Egydio’s procedure as day cases were included in this study. Results The mean penile curvature was 45° and 27.3% of the patients reported mild erectile dysfunction (ED) preoperatively. Partial excision of the calcified plaque was performed in 12.1% of the patients. Partial glans necrosis was recorded in one patient, while haematoma was recorded in 9%, and delayed wound healing in 3%. There was residual curvature (mean 20°) requiring reoperation in 8.2% of the patients. In all, 10% of the patients were dissatisfied with their results, while of the remainder, 75.2% were totally satisfied and 14.8% partially satisfied. ED was reported in 31.8% of the patients (moderate: 17.3% and significant: 2.7%). Conclusions The Egydio geometrical technique for the treatment of penile curvature seems to be a simple, reproducible, safe, and efficient operation.
