We aimed to evaluate ten-year outcomes of penile prosthesis (PP) implantation for the treatment of erectile dysfunction and to assess predictors of early prosthetic infection (EPI). We identified 549 men who underwent 576 PP placements between 2008 and 2018. Univariate and multivariate analyses were used to identify potential predictors of EPI. An EPI predictive nomogram was developed. Thirty-five (6.1%) cases of EPI were recorded with an explant rate of 3.1%. In terms of satisfaction, 82.0% of the patients defined themselves as "satisfied," while partner's satisfaction was 88.3%. Diabetes (P = 0.012), longer operative time (P = 0.032), and reinterventions (P = 0.048) were associated with EPI risk, while postoperative ciprofloxacin was inversely associated with EPI (P = 0.014). Rifampin/gentamicin-coated 3-piece inflatable PP (r/g-c 3IPP) showed a higher EPI risk (P = 0.019). Multivariate analyses showed a two-fold higher risk of EPI in diabetic patients, redo surgeries, or when a r/g-c 3IPP was used (all P < 0.03). We showed that diabetes, longer operative time, and secondary surgeries were the risk factors for EPI. Postoperative ciprofloxacin was associated with a reduced risk of EPI, while r/g-c 3IPP had higher EPI rates without an increased risk of PP explant. After further validation, the proposed nomogram could be a useful tool for the preoperative counseling of PP implantation.

Penile prosthetic implantation represents a cornerstone for patients with organic erectile dysfunction (ED) that is refractory, unsatisfactory, or contra-indicated for other approved medical or mechanical options. In this study, we introduce the "Ghattas technique," wherein we constructed a polypropylene mesh sheath that surrounds and is fixed to a 13-mm malleable prosthesis cylinder, which can increase the cylinder diameter for cases that need a larger prosthesis. All patients underwent preoperative evaluation and completed the five-item International Index of Erectile Function questionnaire (IIEF-5). Postoperative outcomes were evaluated by IIEF-5 and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaires at final follow-up. The mean age of the 23 included patients was 57.9 (standard deviation [s.d.]: 11.4) years and the mean duration of ED was 8.5 (s.d.: 7.9) years. Erection improvement was determined by comparing mean preoperative and postoperative IIEF-5 scores (8.3 [s.d.: 3.9] vs 24.6 [s.d.: 0.6], P < 0.001). High treatment satisfaction was determined according to a mean EDITS score of 94.9 (s.d.: 9.9). The proposed Ghattas technique was safe and effective in our patients, and provides opportunity for cases that need a diameter larger than 13 mm. Further studies are needed to confirm these results.

Inflatable penile prostheses are an important tool in the treatment of medically refractory erectile dysfunction. One of the major complications associated with these prostheses is infections, which ultimately require device explanation and placement of a new device. Over the past several decades, significant work has been done to reduce infection rates and optimize treatment strategies to reduce patient morbidity. This article reviews the current state of knowledge surrounding penile prosthesis infections, with attention to the evidence for methods to prevent infection and best practices for device reimplantation.

Penile prosthesis implantation is the gold standard of surgical therapy for patients with medication-refractory erectile dysfunction. However, this umbrella definition includes significant heterogeneity and associated risk profiles that should be candidly discussed and addressed perioperatively. Factors associated with operative success and patient satisfaction are often surgery specific; however, risk profiling via patient selection, preoperative optimization, proper device selection, and intraoperative consideration are highly correlated. Some examples of common risk profiles include comorbidity(ies) such as cardiovascular disease, diabetes mellitus, prior abdominal surgery, Peyronie's disease, and psychological risk factors. Similarly, integration of surgeon- and patient-amenable characteristics is key to decreasing risk of infection, complication, and need for revision. Finally, patient risk profiling provides a unique context for proper device selection and evidence-based intraoperative considerations.

The global population is collectively getting older, and age is directly correlated with erectile dysfunction (ED). With the advent of effective oral agents and wide availability of the Internet, a larger portion of the population is becoming aware of the different treatment options for men with ED. The penile prosthesis is a definitive and effective treatment for ED which has been available for just over half a century.

6.Future considerations in prosthetic urology.
Asian Journal of Andrology 2020;22(1):70-75
Since their popularization, genitourinary prosthetics have remained a gold-standard therapy for the treatment of erectile dysfunction and stress urinary incontinence and in cases of testicular loss or dysfunction. They have also represented an area of significant innovation, which has contributed to excellent long-term outcomes. Given this history, the objective of the current review was to provide a 5-10-year outlook on anticipated trends and developments in the field of genitourinary prosthetics. To accomplish this objective, a PubMed and patent search was performed of topics relating to penile and testicular prostheses and urinary sphincters. In regard to penile prostheses, findings demonstrated several new concepts including temperature-sensitive alloys, automated pumps, devices designed specifically for neophalluses, and improved malleable designs. With artificial urinary sphincters, new concepts include the ability to add or remove fluid from an existing system, two-piece systems, and new mechanisms to occlude the urethra. For testicular prosthetics, future implementations may not only better replicate the feel of a biological testicle but also add endocrinological functions. Beyond device innovation, the future of prosthetics is also one of expanding geographic boundaries, which necessitates variable cost modeling and regulatory considerations. Surgical trends are also changing, with a greater emphasis on nonnarcotic, postoperative pain control, outpatient surgeries, and adjunctive techniques to lengthen the penis and address concomitant stress incontinence, among others. Concomitant with device and surgical changes, future considerations also include a greater need for education and training, particularly given the rapid expansion of sexual medicine into developing nations.

7.Fundamentals of prosthetic urology.
Asian Journal of Andrology 2020;22(1):20-27
The field of prosthetic urology demonstrates the striking impact that simple devices can have on quality of life. Penile prosthesis and artificial urinary sphincter implantation are the cornerstone procedures on which this specialty focuses. Modern research largely concentrates on decreasing the rates of complication and infection, as the current devices offer superior rates of satisfaction when revision is not necessary. These techniques are also able to salvage sexual function and continence in more difficult patient populations including female-to-male transgender individuals, those with ischemic priapism, and those with erectile dysfunction and incontinence secondary to prostatectomy. This review summarizes modern techniques, outcomes, and complications in the field of prosthetic urology.

8.Biomedical engineering and erectile restoration: design considerations for urologic prosthetics.
Asian Journal of Andrology 2020;22(1):15-19
For patients with moderate-to-severe erectile dysfunction, implantable penile prostheses continue to be a viable treatment. Medical device developers apply design controls during the development cycle to ensure that a product performs as intended in the final use environment. This process relies heavily on the principles of systems engineering and documents every facet of performance, unmet need, and risk. To better understand design philosophy, it is important to frame benchmarked performance outcomes in the context of the ideal state. Careful consideration of erectile anatomy and physiology, including flaccid state, transitional phases, and full tumescence, informs penile prosthesis design philosophy and provides the foundation for product advancement.

With the onset of a metabolic syndrome epidemic and the increasing life expectancy, erectile dysfunction (ED) has become a more common condition. As incidence and prevalence increase, the medical field is focused on providing more appropriate therapies. It is common knowledge that ED is a chronic condition that is also associated with a myriad of other disorders. Conditions such as aging, diabetes mellitus, hypertension, obesity, prostatic hypertrophy, and prostate cancer, among others, have a direct implication on the onset and progression of ED. Characterization and recognition of risk factors may help clinicians recognize and properly treat patients suffering from ED. One of the most reliable treatments for ED is penile prosthetic surgery. Since the introduction of the penile prosthesis (PP) in the early seventies, this surgical procedure has improved the lives of thousands of men, with reliable and satisfactory results. The aim of this review article is to characterize the epidemiology of men undergoing penile prosthetic surgery, with a discussion about the most common conditions involved in the development of ED, and that ultimately drive patients into electing to undergo PP placement.

10.Artificial urinary sphincter surgery in the special populations: neurological, revision, concurrent penile prosthesis and female stress urinary incontinence groups.
Asian Journal of Andrology 2020;22(1):45-50
The artificial urinary sphincter (AUS) remains the standard of care in men with severe stress urinary incontinence (SUI) following prostate surgery and radiation. While the current AUS provides an effective, safe, and durable treatment option, it is not without its limitations and complications, especially with regard to its utility in some "high-risk" populations. This article provides a critical review of relevant publications pertaining to AUS surgery in specific high-risk groups such as men with spinal cord injury, revision cases, concurrent penile prosthesis implant, and female SUI. The discussion of each category includes a brief review of surgical challenge and a practical action-based set of recommendations. Our increased understandings of the pathophysiology of various SUI cases coupled with effective therapeutic strategies to enhance AUS surgery continue to improve clinical outcomes of many patients with SUI.
