El-Achkar A, Khalafalla K, Nguyen TT, Wang R. A systematic review comparing different approaches for inflatable penile prosthesis revision: partial-component exchange, complete-component exchange, or reservoir "drain and retain". Sex Med Rev 2024; 12:519-527. [PMID: 38798020 DOI: 10.1093/sxmrev/qeae035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 04/24/2024] [Accepted: 05/06/2024] [Indexed: 05/29/2024]
Abstract
INTRODUCTION In cases of a noninfected malfunctioning inflatable penile prosthesis (IPP) device, surgeons often opt to exchange all of the device rather than the defective component for fear of an increased infection rate and future mechanical dysfunction. OBJECTIVES To assess whether partial-component exchange of an IPP device has comparable outcomes to complete explant and replacement of an IPP device with or without a retained reservoir. METHODS A systematic review was conducted following the PRISMA 2020 and AMSTAR guidelines. Searches were performed on MEDLINE (Ovid), PubMed, and the Cochrane Library from inception to June 2023, identifying studies reporting outcomes and complications of revision surgery for noninfected malfunctioning IPP devices. Three groups were compared: those undergoing single- or 2-component exchange, those with complete explantation and replacement, and those with replacement of all components while retaining the primary reservoir. RESULTS Analysis included 11 articles comprising 12 202 patients with complete device replacement, 234 with partial device exchange, and 151 with retained reservoirs following revision. Mean ages ranged from 62 to 68 years, with median follow-up times between 3 and 84 months. Partial-component exchange showed a higher infection rate (6.3%) as compared with complete replacement (2.7%) and reservoir retention (3.9%). Similarly, partial exchange had a higher complication rate (23.9%) when compared with complete replacement (11.3%) and reservoir retention (19.6%). Mechanical failure rates for partial exchange were similar across the 3 groups (10%, 2.8%, and 5.8%, respectively). CONCLUSION Partial-component exchange during IPP revision is associated with higher infection and perioperative complication rates but comparable rates of mechanical failure as compared with complete-component replacement, with or without retaining the original reservoir.

Abstract
Objectives To investigate the racial and socioeconomic (income) differences in receipt of and time to surgical care for urinary incontinence (UI) and erectile dysfunction (ED) occurring post-radical prostatectomy (RP) and/or radiation therapy (RT). Materials and Methods Utilizing the Medicare Standard Analytical Files (SAF), a retrospective cohort study was performed on data of patients diagnosed with prostate cancer (PCa) from 2015 to 2021. Patients who underwent RP and/or RT and who subsequently developed UI and/or ED were grouped into four cohorts: RP-ED, RP-UI, RT-ED and RT-UI. County-level median household income was cross-referenced with SAF county codes, classified into income quartiles, and used as a proxy for patient income status. The rate of surgical care was compared between groups using two-sample t-test and log-rank test. Cox proportional hazards modelling was used to determine covariate-adjusted impact of race on time to surgical care. Results The rate of surgical care was 6.8, 3.61 3.07, and 1.54 per 100 person-years for the RP-UI, RT-UI, RP-ED, and RT-ED cohorts, respectively. Cox proportional 'time-to-surgical care' regression analysis revealed that Black men were statistically more likely to receive ED surgical care (RP-ED AHR:1.79, 95% CI:1.49-2.17; RT-ED AHR:1.50, 95% CI:1.11-2.01), but less likely to receive UI surgical care (RP-UI AHR:0.80, 95% CI:0.67-0.96) than White men, in all cohorts except RT-UI. Surgical care was highest among Q1 (lowest income quartile) patients in all cohorts except RT-UI. Conclusions Surgical care for post-PCa treatment complications is low, and significantly impacted by racial and socioeconomic (income) differences. Prospective studies investigating the basis of these results would be insightful.

Abstract
BACKGROUND Despite increases in the lifetime prevalence of anal intercourse, little is known about the safety of inflatable penile prosthesis use during anal intercourse or the forces required for anal penetration. AIM We sought to determine the force required for anal penetration. METHODS A digital force gauge device was secured to a silicone phallus with a length and girth representative of the average male phallus in the United States and inserted into the anal canal of 6 male participants for a total of 5 measurements per participant. The maximum axial forces on insertion were recorded. Participants then completed a survey eliciting demographic information and past experience with receptive anal intercourse. OUTCOMES The outcome measure was the force recorded during insertion of a force gauge device into the anal canal. RESULTS The median maximal force recorded on anal penetration was 26.5 N (2.7 kg; range: 16.1-51.7 N or 1.64-5.27 kg). Participants who engaged in receptive anal intercourse more than once per month tended to use lesser median maximal forces (25.7 N or 2.62 kg) than participants who engaged less frequently in receptive anal intercourse (41.6 N or 4.24 kg). CLINICAL IMPLICATIONS Compared with the forces required for vaginal penetration, anal penetration forces may cause additional mechanical stress to the phallus. STRENGTHS AND LIMITATIONS While the study is limited primarily in its small sample size and in the use of a single device for anal penetration with a set size and rigidity, the resulting findings presented here are to our knowledge the first reported data pertaining the force required for anal penetration. CONCLUSION As the forces required for anal penetration exceeded those for vaginal penetration, clinicians may need to carefully counsel patients on the safe use of an inflatable penile prosthesis for anal intercourse.

Abstract
Penile prosthesis implantation is the definitive treatment for refractory erectile dysfunction, yet exposure to this procedure during training of urology residents is often limited. To assess the effects of resident participation in penile prosthesis surgery, we compared surgical outcomes in a retrospective case series of 253 penile prosthesis surgeries by a single surgeon at the same institution between 2017 and 2020 with the assistance of either a registered nurse first assistant (RNFA) or a resident. Pertinent patient characteristics and surgical complications including device complications, surgical site infection, postoperative bleeding, iatrogenic injury, cardiovascular events, pulmonary events, and urinary retention were documented. Measured outcomes included operative time, Emergency Room (ER) visits, unplanned postoperative visits, pain medication refills, and surgical complications. Compared to RFNAs, resident-assisted penile prosthesis surgery was associated with significant increase in mean operative time (71.4 min vs. 87.9 min, p < 0.01) and postoperative ER visits (3.0% vs. 10.6%, p = 0.03) but not surgical complications (19.7% vs. 20.8%, OR 1.03, 95% CI [0.46 -2.30]) or other measured outcomes. Compared to a dedicated RFNA, Resident assistance increased operative time by approximately 17 min, but did not increase post-operative surgical complications, supporting the notion that resident assistance in these procedures may be appropriate as an integral part of training.

Penile prostheses harbor biofilms driven by individual variability and manufacturer even in the absence of clinical infection. J Sex Med 2023; 20:1431-1439. [PMID: 37837552 DOI: 10.1093/jsxmed/qdad124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/28/2023] [Accepted: 08/30/2023] [Indexed: 10/16/2023]
Abstract
BACKGROUND Culture-based studies have shown that penile prostheses harbor biofilms in the presence and absence of infection, but these findings have not been adequately validated using contemporary microbiome analytic techniques. AIM The study sought to characterize microbial biofilms of indwelling penile prosthesis devices according to patient factors, device components, manufacturer, and infection status. METHODS Upon penile prostheses surgical explantation, device biofilms were extracted, sonicated, and characterized using shotgun metagenomics and culture-based approaches. Device components were also analyzed using scanning electron microscopy. OUTCOMES Outcomes included the presence or absence of biofilms, alpha and beta diversity, specific microbes identified and the presence of biofilm, and antibiotic resistance genes on each prosthesis component. RESULTS The average age of participants from whom devices were explanted was 61 ± 11 years, and 9 (45%) of 20 had a diagnosis of diabetes mellitus. Seventeen devices were noninfected, and 3 were associated with clinical infection. Mean device indwelling time prior to explant was 5.1 ± 5.1 years. All analyzed components from 20 devices had detectable microbial biofilms, both in the presence and absence of infection. Scanning electron microscopy corroborated the presence of biofilms across device components. Significant differences between viruses, prokaryotes, and metabolic pathways were identified between individual patients, device manufacturers, and infection status. Mobiluncus curtisii was enriched in manufacturer A device biofilms relative to manufacturer B device biofilms. Bordetella bronchialis, Methylomicrobium alcaliphilum, Pseudoxanthomonas suwonensis, and Porphyrobacter sp. were enriched in manufacturer B devices relative to manufacturer A devices. The most abundant bacterial phyla were the Proteobacteria, Actinobacteria, and Firmicutes. Glycogenesis, the process of glycogen synthesis, was among the predominant metabolic pathways detected across device components. Beta diversity of bacteria, viruses, protozoa, and pathways did not differ among device components. CLINICAL IMPLICATIONS All components of all penile prostheses removed from infected and noninfected patients have biofilms. The significance of biofilms on noninfected devices remains unknown and merits further investigation. STRENGTHS AND LIMITATIONS Strengths include the multipronged approach to characterize biofilms and being the first study to include all components of penile prostheses in tandem. Limitations include the relatively few number of infected devices in the series, a relatively small subset of devices included in shotgun metagenomics analysis, and the lack of anaerobic and other expanded conditions for culture. CONCLUSION Penile prosthesis biofilms are apparent in the presence and absence of infection, and the composition of biofilms was driven primarily by device manufacturer, individual variability, and infection, while being less impacted by device component.

Abstract
A penile prosthesis/implant is an excellent option for men with erectile dysfunction refractory to medical treatment or with contraindications to medical management. In this narrative review, we discuss the different types of penile prostheses and the considerations for patient and device selection to maximize satisfaction. There are three main prosthesis types to choose from: three-piece inflatable devices, two-piece inflatable devices, and malleable/semirigid devices. The three-piece devices are the gold standard in advanced economy countries but require reservoir placement and manual dexterity, which can be limiting to some patients. The two-piece inflatable devices are a good option for patients who have standard-sized penises, lack significant penile pathology, have limited dexterity issues, or should avoid reservoir placement due to potential complications. The malleable devices are popular in countries where insurance coverage is limited but are increasingly used in advanced economy countries for length conservation in specific patient populations. Finally, not every patient needs an implant, and assessing partner sexual function is an important consideration for patient-partner satisfaction. Surgeons need to be familiar with the strengths and limitations of each device and the patient characteristics that will yield the best outcome from penile prosthesis surgery.

Abstract
This paper presents a computational study to investigate the mechanical properties of human penile tissues. Different experimental testing regimes, namely indentation and plate-compression tests, are compared to establish the most suitable testing regime for establishing the mechanical properties of the different penile tissues. An idealised MRI-based geometry of the penis, containing different tissue layers, is simulated using the finite element (FE) method to enable realistic predictions of the deformation of the penis. Unlike the linear elastic models used in the literature to-date, hyperelastic isotropic/anisotropic material models are used to capture material nonlinearity and anisotropy. The influence of material properties, morphological variations, material nonlinearity and anisotropy are investigated. Moreover, the implantation of an inflatable penile prosthesis (IPP) is simulated to assess the effects of the implantation procedure, material nonlinearity, and anisotropy on tissue stresses. The results indicate that the interior layers of the penis do not affect the overall stiffness of the penis in the indentation test, while the plate-compression test is able to capture the effects of these layers. Tunica Albuginea (TA) is found to have the most significant contribution to the total stiffness of the penis under load. It can also be observed that buckling occurs in the septum of the penis during the compression tests, and different morphologies dictate different compressive behaviours. There is a clear need for future experimental studies on penile tissues given the lack of relevant test data in the literature. Based on this study, plate-compression testing would offer the most insightful experimental data for such tissue characterisation.

Abstract
Erectile dysfunction (ED) is the inability to get and maintain an adequate penile erection for satisfactory sexual intercourse. Due to its negative impacts on men's life quality and increase during aging (40% of men between 40 and 70 years), ED has always attracted researchers of different disciplines, from urology, andrology and neuropharmacology to regenerative medicine, and vascular and prosthesis implant surgery. Locally and/or centrally acting drugs are used to treat ED, e.g., phosphodiesterase 5 inhibitors (first in the list) given orally, and phentolamine, prostaglandin E1 and papaverine injected intracavernously. Preclinical data also show that dopamine D4 receptor agonists, oxytocin and α-MSH analogues may have a role in ED treatment. However, since pro-erectile drugs are given on demand and are not always efficacious, new strategies are being tested for long lasting cures of ED. These include regenerative therapies, e.g., stem cells, plasma-enriched platelets and extracorporeal shock wave treatments to cure damaged erectile tissues. Although fascinating, these therapies are laborious, expensive and not easily reproducible. This leaves old vacuum erection devices and penile prostheses as the only way to get an artificial erection and sexual intercourse with intractable ED, with penile prosthesis used only by accurately selected patients.

Abstract
PURPOSE OF REVIEW Despite the current surgical advances and patients' satisfactions after penile prosthesis (PP) implantation, there has been paucity of data on reported partner satisfaction and their quality-of-life (QoL). Our objective was to summarize the current literature on partner satisfaction for both heterosexual and non-heterosexual populations, respectively. We specifically conducted a systematic review according to the Cochrane and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards, and stratified studies into three tiers by methodological rigor. RECENT FINDINGS After an initial search of 172 articles, 33 studies met the inclusion criteria for the final review: 30 for heterosexual partner satisfaction, and 3 for LGBTQ patient satisfaction were included due to lack of published literature on partner satisfaction for LGBTQ patients. For heterosexual partner satisfaction, 10 studies were classified as Tier 1, 11 studies were classified as Tier 2, and 9 studies were classified as Tier 3. From an initial search of 13 records, three studies consisting of 272 patients met the inclusion criteria for our LGBTQ review. Across all the tiers, studies noted satisfaction rates between 50 and 90% and improved satisfaction and sexual QoL metrics compared to pre-surgery rates. That said, partner satisfaction rates were also consistently lower than patient satisfaction rates. Although the range of evidence quality varies, the available literature suggests significant improvements in and relatively high rates of partner satisfaction after PP implantation. Given the diversity of study designs and widespread use of non-validated or non-specific questionnaires in the current literature, future research should focus on prospective studies and/or data collection using validated, PP-specific questionnaires.

Abstract
BACKGROUND Online health information (OHI) has become widely accessible and affects patient decisions regarding their healthcare. The purpose of this study was to assess the readability, quality, and accuracy of information available to patients online about penile prosthesis implants (PPIs). METHODS We performed a Google search using the keywords "penile implant" and "penile prosthesis." The first 30 search results for both terms were analyzed, and advertisements, news articles, duplicates, and videos were excluded. Websites were categorized as institutional, commercial, and personal/patient support. Readability of each website was determined using the Flesch-Kincaid grade level (FKGL) readability formula within the readable tool. Quality was measured by Health On the Net (HON) certification status and the DISCERN scoring method. For website accuracy, a score of 1-4 (1=0-25%, 2=25-50%, 3=50-75%, and 4=75-100%) was assigned. RESULTS Forty-four websites met the criteria (23 institutional, 12 commercial, and 9 personal/patient support). The mean total FKGL score was 9.55. No statistical difference was detected between mean FKGL for each website category (p=0.69). Only eight websites (18%) scored ≤8th-grade reading level (average US adult level), while 36 (82%) were >8th-grade level. Mean total DISCERN sum score was 39.74/75, with no statistical difference in mean DISCERN score between website types (p=0.08). Over half (55%) of the websites were defined as "very poor" or "poor" quality by DISCERN scoring. Mean total overall quality rating was 2.67/5. HON certification was verified for only nine websites (20%). Twenty-five percent of websites were classified as 0-25% accurate, 23% were 25-50% accurate, 30% were 50-75% accurate, and 23% were 75-100% accurate. CONCLUSION Most information on the Internet about PPIs is reasonably accurate; however, the majority of websites are deficient in quality and unreadable to the average patient, irrespective of website type.

Abstract
Erectile dysfunction is a common disease of the male reproductive system, which seriously affects the life quality of patients and their partners. At present, erectile dysfunction is considered as a social-psychological-physiological disease with complex etiology and various treatment methods. Oral PDE5I is the first-line treatment for erectile dysfunction with the advantages of high safety, good effect and non-invasiveness. But intracavernosal injection, hormonal replacement therapy, vacuum erection device, penile prosthesis implantation can also be alternative treatments for patients have organic erectile dysfunction or tolerance to PDE5I. With the rapid development of technologies, some new methods, such as low-intensity extracorporeal shock wave and stem cell injection therapy can even repair the organic damage of the corpora cavernosa. These are important directions for the treatment of male erectile dysfunction in the future. In this mini-review, we will introduce these therapies in detail.

Abstract
Priapism is defined as a full or partial erection lasting greater than 4 h due to a fault in the normal detumescence mechanism of the penis. We describe the case of a confused 73-year-old gentleman presenting with painless priapism, a 2 cm non-tethered lesion in the scrotum and a vague palpable pelvic mass. On the presumption that this was a case of high-flow non-ischaemic priapism secondary to pelvic malignancy, the urology registrar attempted corporal body aspiration. Clear fluid was aspirated and the penis became flaccid instantly. A CT scan performed to determine the presence of a pelvic mass, revealed a penile prosthesis and artificial reservoir. While iatrogenic penile prosthesis malfunctions are well established in the literature, a case managed as an acute priapism is yet to be reported. This case teaches us the importance of taking an adequate medical history and clinical examination prior to formulating a diagnosis and administering treatment.

Arch Ital Urol Androl 2022; 94:65-69. [PMID: 35352528 PMCID: PMC10165345 DOI: 10.4081/aiua.2022.1.65] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 01/26/2022] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVES Evidence regarding demand trends for erectile dysfunction (ED) treatments are scarce in South America. This study aims to evaluate trends in ED treatments in Chile over a 10-year period (2010- 2020) and estimate the potential number of candidates for penile prosthesis. MATERIALS AND METHODS Sales trends of pharmacological treatments and penile prosthesis were obtained from market studies. The potential number of candidates for penile prosthesis implantation was calculated by crossing epidemiological data with previously reported ED prevalence, proportion of sexually active men, percentage of men seeking medical assistance for ED, and the proportion of patients who are non-responders to ED oral drug therapies Results: In the 10-year studied period, the Chilean male population older than 50 years increased 34.7%, with an average annual variation (AAV) of 3.4%. For the same period, the sales of oral drug therapies for ED increased by 71.3% (AAV 6.2%), the sales of intracavernosal vasoactive agents (ICVA) decreased by 0.4% (AAV -0.2%), and penile prosthesis sales increased by 113% (AAV 6.7%). We estimated that only 0.05% of sexually active men older than 50 years old with ED who sought medical assistance finally had a penile prosthesis implanted to manage their condition. CONCLUSIONS Demand for ED oral drug therapies significantly increased in Chile during the last decade, while ICVA remained stable. The annual rate of penile prosthesis implantation increased. However, the gap between the potential penile prosthesis candidates and the actual number of devices implanted is suspected to remain extremely high.

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.

Abstract
Penile implants are surgically inserted devices used for the treatment of erectile disfunction. Improvements in surgical techniques and in the manufacturing of these implants have reduced the risk of intra- and postoperative complications and increased the popularity and use of this therapeutic option. Routine imaging is not recommended before penile prosthesis surgery. Malleable penile prostheses use noninflatable shafts inserted into each corpus cavernosum, which appear hypointense on T1- and T2-weighted MR images. Inflatable penile prostheses (IPPs) may consist of two or three parts and are composed of two cylinders inserted into the corpora cavernosa that are filled with a saline solution to produce rigidity. These appear homogeneously T2 hyperintense and the silicone-based covering of the cylinders appears T2 hypointense, thereby clearly delineating the cylinders. In the case of three-piece IPPs, a reservoir containing the fluid may be placed in the pelvis. The most frequent complications are related to infection and mechanical failure, the latter being more common in IPPs because more components are involved. Less common complications include malpositioning. Detection and management of postoperative complications are challenging, and MRI plays a crucial role as it permits evaluation of the positioning and configuration of the prosthesis components, as well as assists in functional evaluation of IPPs when images are obtained of both the flaccid and inflated states. ©RSNA, 2021.

[PMID: 37057438 DOI: 10.1016/j.jsxm.2021.06.020] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 06/21/2021] [Accepted: 06/30/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND No validated English language patient-reported outcome (PRO) currently exists that assesses satisfaction with inflatable penile prosthesis (IPP). Satisfaction data have been largely based primarily on surgeon assessment of patients or using questionnaires that have not been designed for this purpose. AIM To develop an English-language validated PRO that assesses patient satisfaction after IPP surgery. METHODS Initially, a literature review and discussions with experts defined domains important to IPP satisfaction (pain, appearance, function, overall satisfaction). The initial 35-item Satisfaction Survey for Inflatable Penile Implant (SSIPI) was developed. Cognitive interviews were then performed with IPP patients (n = 12) to gain feedback on the SSIPI domains and items. These data were used to modify SSIPI with the addition of 2 questions for a final item number of 37. Patients from 4 centers, who were between 6 months and 5 years after IPP, were administered the questionnaire through RedCap. Reliability statistics and content analysis were used to winnow questions to yield the final 16-item version of the SSIPI. Internal consistency was assessed via Cronbach's alpha and item-total correlation. Test-retest reliability was assessed via intraclass correlation coefficients using baseline and 2-week data. For convergent validity, the Erectile Dysfunction Inventory of Treatment Satisfaction and the Self-Esteem and Relationship (SEAR) questionnaire were used. For discriminant validity, the International Prostate Symptom Score (IPSS) was used. Confirmatory factor analysis was used to assess the factor structure of the SSIPI. OUTCOMES Internal consistency, test-retest reliability, convergent and discriminant validity, and confirmatory factor analysis were assessed. RESULTS 118 men were surveyed. Mean age was 66.8 ± 9.5 years. The 16-item SSIPI showed high internal consistency with an overall Cronbach's Alpha of 0.97 (domains 0.85-0.89). Item-total correlations for individual items to subscales ranged from 0.60 to 0.91. The overall test-retest reliability was 0.94 (domains 0.87-0.93). Erectile Dysfunction Inventory of Treatment Satisfaction and Self-Esteem and Relationship had correlations of 0.84 overall (domains 0.57-0.79) and 0.47 overall (domains 0.34-0.44), respectively. International Prostate Symptom Score (discriminant validity) had correlations of -0.29 overall (domains -0.17 to -0.31). CLINICAL IMPLICATIONS SSIPI is the first English-language validated IPP satisfaction PRO. This will enable clinicians to collect satisfaction data in a standardized way. STRENGTHS AND LIMITATIONS As strengths we have used a rigorous psychometric process and have no industry sponsorship. Limitations include small numbers of specific subpopulations. CONCLUSION The SSIPI has demonstrated robust psychometric properties. Salter CA, Bach PV, Jenkins L, et al.

Abstract
BACKGROUND Malleable [MPP] and inflatable [IPP] penile prosthesis surgery for the management of erectile dysfunction is a reliable treatment option with high success rates and excellent patient satisfaction; however, Medicaid coverage transparency is poor leaving a knowledge gap in this population. AIM The present study seeks to assess Medicaid coverage for MPP and IPP by state as evidenced by inclusion in publicly available physician fee schedules. METHODS State Medicaid websites were utilized to access public physician fee schedules. Individual search queries were performed for CPT codes 54400 and 54405 which represent insertion of MPP and IPP, respectively. Data were recorded for each device, including the coverage status, physician fees, and the presence of clear documentation of a prior authorization requirement. OUTCOMES Medicaid physician fee schedules were accessible for 49 out of 50 US states, and 28 states reported coverage for at least one type of penile prosthesis. RESULTS Two states reported coverage for MPP only, one state reported coverage for IPP only, and 24 states reported coverage for both devices. One state reported that it did not cover either device, but listed coverage for a self-contained IPP (CPT 54401) only. Mean physician reimbursement was $477.15 (290.82-$1175.50) for MPP placement and $691.76 (421.68-$1794.27) for IPP. Eleven states documented prior authorization requirements within their fee schedules, while the remaining 17 states did not. Criteria for approval for prior authorization were not clearly stated in any fee schedule. CLINICAL IMPLICATIONS Efforts to clearly document approval criteria and educate Men's Health providers on available coverage could result in a significant improvement in sexual satisfaction in the Medicaid population. STRENGTHS AND LIMITATIONS Graphical representation of states offering Medicaid penile prosthetic coverage and physician reimbursement ranges are provided with comparison to Medicare rates. Limitations include heterogeneity in fee schedules, lack of prior authorization requirement details, inability to correlate to successful claims data, and the evolving nature of Medicaid coverage for the given procedures. CONCLUSIONS Medicaid coverage exists for penile prosthetic surgery in 28 states, although often with significant, non-transparent prior authorization criteria. Barnard JT, Grimaud L, Yafi FA.

Abstract
CONTEXT Penile prosthesis is a durable and effective treatment for erectile dysfunction (ED). Even as other treatment options for ED have been brought to market, penile prosthetic surgery remains a mainstay for urologists treating ED. No systematic study has yet summarized the global trends in penile prosthetic surgery. OBJECTIVE To systematically review studies of trends in penile prosthetic surgery to determine global movements in implantation rates, malleable versus inflatable prosthetic surgery, inpatient versus outpatient implantation surgery, proportion of men with ED undergoing penile prosthetic surgery, and prosthetic cost. EVIDENCE ACQUISITION A systematic review of MEDLINE, EMBASE, Cochrane Library, and ClinicalTrials.gov was performed for studies assessing trends in penile prosthetic surgeries and costs associated with penile prosthetic device and inclusive surgical costs. EVIDENCE SYNTHESIS Twenty-seven studies were identified during the systematic review, comprising 447,204 penile prosthetic surgeries reported from 1988 to 2019. A trend analysis demonstrates that rates of penile prosthetic surgery declined dramatically in the late 1980s and early 1990s, but have demonstrated modest growth since the mid-2000s. Outpatient inflatable penile prosthetic surgery has strongly trended upward. Costs of penile prosthetic device have matched the rate of inflation, but inclusive surgical cost has radically outpaced inflation. Growth has mainly been seen in the USA, with a more modest global growth. CONCLUSIONS Penile prosthesis remains a viable option for the treatment of ED. Trends such as outpatient surgery and inflatable penile prosthesis placement may be driving the recent steady growth of penile prosthetic surgeries, but surging inclusive surgical cost may present a barrier for some patients without insurance coverage. PATIENT SUMMARY Penile prostheses continue to be an important treatment for erectile dysfunction. While the volume of penile prosthetic surgeries dropped when phosphidiesterase-5 inhibitors became available, prosthetic surgery is becoming more patient centric, as seen by increases in inflatable prosthetic placement and outpatient surgery.

Abstract
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.

Abstract
OBJECTIVE To characterize the safety and practice patterns of artificial urinary sphincter (AUS) placement on a population level. Increasingly AUS implantation has shifted to be an outpatient surgery; however, there is a lack of large-scale research evaluating factors associated with early (≤ 24 hours) versus late (>24 hours) discharges and complications in men following AUS placement. We utilized the National Surgical Quality Improvement Program (NSQIP) database to identify and compare factors and outcomes associated with each approach. METHODS NSQIP database was queried for men undergoing AUS placement between 2007 and 2016. Patients were classified as either early discharge (ED ≤ 24 hours) and late discharge (LD > 24 hours). Baseline demographics, operating time, and complications were compared between the 2 groups. Multivariate logistic regression evaluated factors associated with discharge timing and 30-day complications. RESULTS A total of 1176 patients were identified and were classified as ED in 232 and LD in 944 patients. Operative time was shorter in ED (83 minutes) compared to LD (95 minutes, P < .001). Hypertension was more prevalent among LD patients (60.3% vs 69.1% for ED and LD respectively, P < .001). The 30-day complication rate was similar in both groups (ED: 4.3% vs LD: 3.4%, P = .498). Multivariable analysis revealed that surgery after 2012 was associated with ED (OR = 3.66, P < .001). CONCLUSION At the national level, there are no differences in postoperative morbidity between early and late discharges. There is a trend toward more ED, specifically after 2012. A prospective study on the feasibility and safety of outpatient AUS is needed.

[PMID: 32941945 DOI: 10.1016/j.urology.2020.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Revised: 08/24/2020] [Accepted: 09/02/2020] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To identify factors associated with patient willingness to consider surgical treatment for erectile dysfunction (ED) prior to urologic consultation. METHODS A prospective database of patients presenting to the sexual health clinic at our institution was created from 2014 to 2018, consisting of previsit patient questionnaires and clinical information. Univariable and multivariable logistic regression analysis was performed to determine factors associated with consideration of surgery and decision to undergo surgery. RESULTS Of 1359 men presenting to the clinic, 991 men had a chief complaint of ED with 630 (63.6%) considering surgery. On multivariable analysis, factors significantly associated with previsit willingness for surgery included history of diabetes mellitus (P = .0009), increasing symptom bother (P <.0001), and decreasing relationship duration (P = .0005). Approximately 16% (162/991) patients considering surgery prior to consultation ultimately underwent penile implant insertion. Multivariable analysis demonstrated that older age (P = .003), history of diabetes mellitus (P = .03), lower international index of erectile function-EF domain (P = .0009) and history of intracavernosal injection therapy (P <.0001) were significantly associated with proceeding to ED surgery. Initial declaration of willingness to undergo ED surgery led to nearly 8-fold increased odds for surgery (P <.0001). CONCLUSION Over 60% of patients presenting for ED consultation considered surgical intervention, of whom 25% underwent penile prosthesis. Both patient and relationship factors were predictors of surgical willingness. Previsit surgical willingness was associated with highest odds of eventual decision for surgery, suggesting that knowledge of ED treatment options in the general public may play a role. Our findings highlight opportunities for shared decision-making in a patient-centered model of care.

A prospective study analyzing both inflation and deflation preference for commonly available inflatable penile prostheses. Int J Impot Res 2020; 33:652-659. [PMID: 32778772 DOI: 10.1038/s41443-020-0339-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 07/02/2020] [Accepted: 07/24/2020] [Indexed: 11/08/2022]
Abstract
Despite popularity, satisfaction rates of inflatable penile prosthesis (IPP) use can be improved by evaluating the ability to operate devices in the preoperative setting. The purpose of this study was to prospectively analyze the preference of three commonly available IPPs. In total, 125 IPP-naïve men 60 years of age or older were prospectively recruited from an outpatient Urology clinic from June 2019 to January 2020. A questionnaire standardized to all encounters was utilized to collect demographics, selected medical information, and key pinch strength. Participants were then asked to rank three models in terms of preference (from 1 to 3, 1 representing most preferred) for each inflation and deflation in a double-blinded manner. Statistical analysis was performed using ANOVA, a Chi-square test and multivariable logistical regression analysis. The results demonstrated preference for Coloplast Titan (44%) for inflation, and preference for AMS 700 (40%) for deflation. Men who preferred the Coloplast Titan inflation had a lower chance of preferring the AMS 700 MS deflation (OR = 0.29; p = 0.010) and Coloplast Titan Touch deflation (OR = 0.27; p = 0.012). Preference for Coloplast Titan was weakly associated with participant history of coronary artery disease (OR = 5.96, p = 0.006) and osteoarthritis (OR = 3.04, p = 0.044). Neither key pinch strength nor age was associated with preference for a particular model. IPP-naïve men over 60 years favor Coloplast Titan for inflation and AMS 700 for deflation, and men who preferred the Coloplast Titan for inflation were less likely to choose the AMS 700 MS or Coloplast Titan Touch for deflation. Further studies should aim to confirm these findings.

Abstract
Inflatable penile prosthesis (IPP) infections are undeniably devastating for patient and surgeon alike. While less common in this modern era, the landscape of prosthesis infection is shifting. Continued examination of risk factors for infection and re-evaluation of common practices remain critical should we aim to advance the field. Quality research on this topic is limited by several factors, among which small sample size and lack of coordinated effort pose the most precarious of challenges. Nonetheless, careful analysis of available data in conjuncture with judicious utilization of established research from other prosthetic fields can help us better grasp the issue at hand. In this review, we aim to do exactly that-to examine available evidence in an effort to discern fact from fiction. In this first part of the three part series, we aim to summarize our understanding of the pathogenesis behind prosthesis infections, explore known preoperative risk factors, and discuss intraoperative considerations for infection prevention. In the second part of this series, we will examine the game changing effect of infection retardant implant coatings. Part three of the series details postoperative prevention strategies, reviews salvage techniques, and discusses additional key considerations.

Abstract
INTRODUCTION Penile prosthesis implant is a safe and effective option in erectile dysfunction patients, being implant procedures safe with a low risk of infection. However, when infection occurs, it represents a concrete problem for both surgeon and patient. METHODS This is a comprehensive review of all issues relating to prosthesis infection, including causes and risk factors, methods of prevention, and management. We analyzed all preoperative and perioperative factors, which can play a role in infection of the device. RESULTS Infection of penile prosthesis implant is hard to manage and correct. While the incidence of infection following first implant is up to 3%, in cases of re-implant surgery, the rate can reach as high as 18%. Many articles were found addressing prevention and treatment of penile prosthesis infection, and many analyzed all relevant pre- and perioperative factors associated with penile prosthesis implant. Although such factors have been well studied, there is no clear consensus worldwide on certain topics. CONCLUSIONS Penile prosthesis implant is a safe and effective option. Despite infection is a rare event, surgeons should follow strictly pre-, intra- and postoperative recommendations in order to reduce the risk of device's infection. An appropriate antibiotic therapy should be tailored on patient's characteristics and pathogens isolated.

Abstract
Purpose The Accreditation Council of Graduate Medical Education (ACGME) establishes surgical minimum numbers of cases for urologic training. Currently there is not a requirement for microsurgery, likely from a belief that programs do not offer exposure. In an effort to evaluate the availability of microsurgery training among urology residency programs we surveyed the programs. Materials and Methods We obtained a list of the 138 ACGME-accredited urology residencies and contact information the American Urology Association (AUA). We contacted the residency programs by phone and e-mail. For programs that did not reply, we performed a search of the program website. We answered 3-questions to assess resident subspecialty training in microsurgery and used penile implant and artificial urinary sphincters as a comparison. Data are reported as frequencies. Results We obtained data from 134 programs (97.1%). A total of 104 programs (77.6%) had fellowship-trained physicians for training in microsurgery, 86.6% for penile implants, and 88.8% for artificial urinary sphincters. The percentage of fellowship-trained microsurgeons per program did not vary significantly when comparing the different sections of the AUA. The northeast and southeast sections had the lowest percentage (67% and 68%). Conclusions Nearly 80% of urology residency programs have a fellowship-trained microsurgeon on faculty, we therefore believe that microsurgery should be added as part of the ACGME minimums. In order to provide an equal exposure to all graduating urology residents, urology residency programs that lack microsurgery should identify potential faculty with fellowship training.

Abstract
Background Penile prosthesis implantation represents the gold standard of treatment for severe or medically refractory erectile dysfunction (ED). We sought to address the paucity of currently available literature about global penile prosthesis usage in regard to geography, patient age, surgical approach, implanter volume, and etiology of ED. Methods From device manufacturer information, we compiled data on over 63,000 implants performed worldwide. Data was grouped and then analyzed to examine trends in penile implantation between the years of 2005-2012. Results The number of implants was seen to steadily increase over the study period. Of the 63,013 total procedures recorded, 85.9% were performed within the United States. 60-78% of procedures were done using the penoscrotal (PS) approach, with only Belgium/Netherlands as an outlier with an infrapubic (INF) majority. The US was notable for having an increasing number of implanters doing 16-30, 31-50, or >100 implants yearly. Etiology of ED worldwide was variable, but "organic," post-prostatectomy, and diabetes accounted for the vast majority of cases worldwide. Conclusions Penile prosthesis implantation is an increasing practice, as evidenced by a steady increase in the number of implants performed over a 7-year study period. Acceptance of this treatment option for ED is variable by region with the US leading the annual number of implantations by a wide margin. Worldwide, there appears to be a predominance of surgeons placing implants via the PS approach.

Abstract
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.

Abstract
INTRODUCTION Medical websites and discussion boards are commonly used by patients to obtain information. The online forum FrankTalk.org provides a venue specifically for men to discuss sexual dysfunction and particularly inflatable penile prosthesis (IPP). By querying and better understanding the content of this forum related to implants, we can better understand patient concerns before and after IPP. AIM The aim of this study is to understand the main topics being discussed about IPPs online and to use these topics to understand patient concerns and patient needs and to improve care. METHODS Messages posted in a 6-month window from January 2018 to June 2018 under the topic "Implant" were identified on FrankTalk.org. Posts were broken down into preoperative and postoperative and then organized using a 3-stage analysis to determine central themes of each post: open coding, axial coding, and selective coding. MAIN OUTCOME MEASURE The primary outcome measure is the prevalence of each selective code. RESULTS Of all 587 posts, 304 were written preoperatively with the most common theme being "Size" (23.0%), followed by "seeking support" (18.4%). 283 posts were considered postoperative, of which the most common theme was "Concern about healing" (22.6 %) which questioned if they needed to see a physician, followed by size concerns (20.1%).When analyzed with the 3-stage coding system, there were a total of 41 axial codes which were organized into 6 selective codes: "Social Support" (27.8% of all posts), "Pre-Operative Worries" (23.58%),"Technical Issues" (11.1%), "Prosthesis Logistics" (14.37%), "Post-Operative Worries" (20.22%), "Forum and Misc" (2.93%) for topics outside the scope of penile prosthesis. CLINICAL IMPLICATIONS The percentage of men seeking medical opinion is concerning, and providers should consider using resources to better educate patients on normal postoperative findings. Implanters should continue to preoperatively counsel patients on size-related changes with surgery. STRENGTH & LIMITATIONS Strengths include the use of a common online website for men to discuss IPPs and a systematic coding system. Limitations include the applicability of these results to nonheterosexual men as these are likely oversampled in this population. The inherent bias of those willing to post on an online forum may have influenced results along with no oversight for factual accuracy. CONCLUSION Patients use online discussion boards like FrankTalk.org for social support, medical advice, and validation of their concerns. Providers should be aware of these online topic focuses to help open a discussion with patients about concerns they may feel are difficult to approach with providers. Lu JY, Miller EJ, Welliver C.

Abstract
INTRODUCTION Penile prosthesis (PP) implantation is the treatment of choice for refractory erectile dysfunction (ED). They show a high satisfaction rate (75%-100%) and a complication rate that varies between 2.1% and 28.8%. The standard surgical technique includes dilatation of the corpora cavernosa (CC) prior to the insertion of the cylinders. This step takes time and is critical for the occurrence of complications. The aim of this study is to describe the results of a series of PP implanted using the techniques with and without dilatation of the CC. MATERIALS AND METHODS One-hundred and 20 patients with refractory ED in whom a PP was implanted by 2 surgeons in different centers. Comorbidities, operative characteristics, satisfaction and postoperative complications were evaluated. RESULTS The average age was 61±9.6 years. The most prevalent comorbidities were: history of radical prostatectomy, high-blood pressure and diabetes mellitus. Forty-two malleable and 78 hydraulic prostheses were implanted. Eleven patients had a previous PP. The median operative time was 70minutes (35-140). The satisfaction reported was 95.8%. Ten patients presented complications. In the group in which the surgery was performed without dilatation of the CC (n=80), the operative time was shorter (62.5minutes [35-105] versus 90minutes [60-140] respectively, p<0.0001). There was no difference in complications (p=0.73) or levels of satisfaction (p=0.196) when comparing the technique with and without dilatation of the CC. CONCLUSION In our series, a shorter operative time was observed with the technique without dilatation of the CC, but there were no differences in complications. A prospective and randomized study is required to make a stronger recommendation regarding to dilatation of the CC.

Abstract
BACKGROUND To evaluate the cost-effectiveness of alternate erectile dysfunction (ED) management options after failed first line phosphodiesterase-5-inhibitors (PDE5-I). METHODS An empiric, repetitive decision tree analysis model was constructed using literature review and expert clinical judgement. This assessed the expected costs and quality adjusted life years (QALYs) of decision alternatives over a 10-year period. The model incorporated interventions including alternate PDE5-Is, intracorporal injections (ICI) with alprostadil or trimix (alprostadil, phentolamine, and papaverine), and inflatable penile prosthesis placement (IPP) and included respective risks of failure, subsequent interventions, and other complications (including priapism risk). Average model QALY estimates obtained from the literature were as follows: ED =0.56, successful alternate PDE5-I =0.70, successful ICI =0.70, and successful IPP =0.78. Cost data were calculated from a high-volume academic center and published manufacturer data. RESULTS Over the 10-year period, IPP placement was the most cost-effective management option per preserved QALY (QALY =7.82, cost =$22,009/10 years) as compared to ICI alprostadil (QALY =8.51, cost =$62,890/10 years), ICI trimix (QALY =8.47, cost =$48,617/10 years) and alternate PDE5-I (QALY =7.73, $52,883/10 years). CONCLUSIONS Using expert opinion and published utility, cost, and complication data in a decision analysis, we demonstrated that IPP placement is the most cost-effective ED intervention following failed initial PDE5-I over a 10-year period as compared to alternate treatment options. Such cost-effectiveness outcomes may be used in ED management counseling.

Abstract
Introduction Inflatable penile prosthesis has become an important treatment modality for men with erectile dysfunction that is refractory to medication. Despite high levels of patient satisfaction following inflatable penile prosthesis placement and inflatable penile prosthesis coverage by Medicare, coverage by commercial insurance providers is unknown. The purpose of this study was to determine the coverage of inflatable penile prosthesis by commercial insurance providers. Methods Following institutional review board approval all men with erectile dysfunction interested in obtaining inflatable penile prosthesis at our tertiary care center between January 2016 and December 2017 were evaluated. We reviewed billing records for CPT code 54405 during the study period to evaluate the insurance provider for all men who received an inflatable penile prosthesis. We also reviewed a manually maintained record of excluded or denied inflatable penile prosthesis claims for men who desired inflatable penile prosthesis but could not obtain it. Through medical record review we recorded the etiology of erectile dysfunction and the specific type of insurance policy for each man. Results Medicare is the most common insurer for inflatable penile prosthesis, insuring 87 of 220 (39.5%) men seeking inflatable penile prosthesis between 2016 and 2017. Among the remaining 127 men seeking inflatable penile prosthesis with commercial insurance coverage 61 (48.0%) were unable to obtain the device due to exclusions in their coverage or denials. Among commercially insured men seeking inflatable penile prosthesis 77 (62.6%) and 37 (30.0%) had health maintenance organization and preferred provider organization plans, respectively. The most prevalent indications for inflatable penile prosthesis among the entire study population were radical prostatectomy (30.9%), organic erectile dysfunction (30.5%) and diabetes mellitus (20.9%). Conclusions The largest insurer for inflatable penile prosthesis in the Miami region is Medicare. While some patients seeking inflatable penile prostheses can receive insurance coverage, a large percentage (48.0%) are not able to receive coverage despite having a medical necessity for the treatment of erectile dysfunction.

Abstract
INTRODUCTION Penile prosthesis placement is the gold standard for the treatment of erectile dysfunction (ED) refractory to medical therapy; however, limited data exist on the long-term outcomes of these devices. AREAS COVERED A PubMed search focused on long-term outcomes of penile prosthetics was performed. Studies with a follow-up of less than 5 years were excluded. Included studies were arranged chronologically by implant date to identify trends in device lifetime. Data were further scrutinized to separate device failure secondary to mechanical malfunction from device failure secondary to infection. EXPERT OPINION Limited data prevent accurate 15-year predictions for modern prosthetics. The 5- and 10-year overall survival of modern prosthetics is estimated to be 90.4% and 86.6%, respectively. Infection rates are estimated to be 1.5% and 1.8% at 8 and 10 years, respectively. While great strides have been made in device design, there is still potential for advancement in both infection rate reduction and mechanical improvement. The combination of increased collaboration between implanting urologists and engineers from prosthetic device companies and improved, prospectively collected data will usher prosthetic urology into its next era.

Abstract
PURPOSE OF REVIEW To provide an evidence based discussion of preoperative, intraoperative, and postoperative factors that lead to successful outcomes in penile prosthesis surgery. RECENT FINDINGS In the preoperative period, careful patient selection, appropriate counseling, thorough evaluation, and sufficient time for physical and emotional adaptation to an inflatable penile prosthesis are the key. During surgery, the entire device should be explanted whenever possible. A drain and retain strategy for the reservoir is a safe alternative in situation where the reservoir is not easily removable. The mechanical cleansing of lavage is more important than chemical sterilization. Postoperative instructions should be made clear and nursing phone calls may reduce the number of ER visits. Careful preoperative counseling, attention to intraoperative details, and vigilance in the postoperative period are necessary for a successful outcome with penile prosthesis revision surgery.

Abstract
PURPOSE Inflatable penile prostheses (IPPs) are widely used in the United States, for patients with erectile dysfunction refractory to other treatments. Complications subsequent to IPP insertion include infection, hematoma, fluid leak, component (cylinder/pump/reservoir) complications, and retained previous IPP components. Radiologists are often called upon to identify and characterize these complications utilizing CT prior to intervention. Our paper aims to provide a guide to familiarize radiologists with normal IPP component imaging and review the CT findings of commonly encountered complications. METHODS In this study, we retrospectively reviewed CT reports with descriptions of IPPs from 108 patients. We collected CT images of normal IPP components as well as reevaluated the CT findings of 33 patients with an IPP complication and correlated with immediately subsequent operative report. RESULTS The CT appearance of appropriately positioned normal IPP components in asymptomatic patients and each complication were described and compared to previous literature. CONCLUSIONS CT is a very useful modality to assess an IPP-related complication. It is inexpensive, fast, and immediately available in emergent situations, e.g., infection, hematoma, and component erosion. Additionally, CT is very sensitive and makes it easier to diagnose a system leak. It can identify most cylinder complications and pump malposition and can be extremely helpful to the surgeon in preoperative planning if revision is needed. After this review, the radiologist should be able to identify normal IPP components and their complications.

Abstract
Infections are among the most feared and devastating complications of penile prosthesis infections, often requiring surgical exploration and explantation are prosthesis infections. While the rate of infections have decreased due to antibiotic prophylaxis, antiseptic device preparation, increased sterility in implantation techniques and device modifications, infections still occur at a rate of 1-3%. This article reviews the formation of biofilms on penile prostheses and novel, experimental methods to prevent and eradicate them.

Abstract
Introduction Constraints on surgical resident training (work-hour mandates, shorter training programs, etc.) and availability of expert surgical educators may limit the acquisition of prosthetic surgical skills. As a result, training courses are being conducted to augment the prosthetic surgery learning experience. Aim To evaluate the impact of a hands-on cadaver-based teaching program on resident procedural knowledge and procedural confidence with placement of a penile prosthesis. Main Outcome Measure Changes in procedural knowledge and self-confidence following a focused training program on penile prosthetics. Methods As part of the 2017 Society of Urologic Prosthetic Surgeons and the Sexual Medicine Society of North America Annual Meeting, 31 urology residents participated in a simulation lab in prosthetic urology. The lab included didactic lectures and a hands-on cadaveric laboratory. Participants completed surveys before and after the course. Wilcoxon Signed Rank tests for matched pairs were used to compare respondents’ pre- and postcourse knowledge (% questions answered correctly) and confidence ratings. Prior implant experience was assessed. Results 31 residents participated in this study. The majority of the participants were 4th- (41.9%) and 5th-year residents (38.7%). Participants showed a significant improvement in procedural knowledge test scores (68.8±13.4 vs 74.2 ± 13.0, P < .05) and self-reported increased median surgical confidence levels (4 vs 3, P value < .001) after completion of the cadaveric course. Subgroup analysis demonstrated that residents with prosthetic surgery experience of <10 cases benefited the most. In addition, improvement in surgical confidence levels observed was greater than the improvement in surgical knowledge. The overall cost of the simulation training course was approximately $1,483 per resident. Conclusion Simulation training in prosthetic surgery seems to improve surgical confidence and knowledge. Further research is needed to better understand the benefits and limitations of simulation training. Lentz AC, Rodríguez D, Davis LG.

Abstract
Inflatable penile prosthesis (IPP) has been around since the 1970’s as a durable and one-time cure for erectile dysfunction (ED). For the past 40 years, many changes have been made to make the device better and currently IPP boasts a high percentage of long-term patient satisfaction. The next paradigm shift in IPP treatment for ED is upon us. Funding for ED related medications and devices has been a hot topic in health policy over the last 10 years. This suggests that the device must improve and patient advocacy and education must increase for IPP to remain as a viable solution for ED. In this paper, we conduct a literature search for innovations in IPP and argue that IPP must constantly improve to compete with oral, injectable, shockwave, and potentially gene therapies.

Abstract
Background Commonly utilized as a third-line therapy for erectile dysfunction (ED) management, the penile prostheses have become a staple treatment for ED refractory to pharmacological interventions. There is however a paucity of data in the literature pertaining to short-term adverse outcomes following penile prosthesis surgery. We thus sought to leverage the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) to evaluate such outcomes within 30 days of surgery in these patients. We hypothesized that such data will lead to a more informed patient-physician consultation. Methods Relying on the ACS-NSQIP database [2005–2013], patients undergoing penile prosthesis placement were identified utilizing the Current Procedural Terminology (CPT) codes: 54400, 54401, 54405, 54406, 54407, 54408, 54410, 54411, 54416 and 54417. Outcomes assessed included system-wise categorized complications, length-of-stay (LOS), and re-intervention, readmission and 30-day mortality rates. Descriptive statistics were used to analyze available data. Multivariate analysis could not be performed due to small sample size. Results Overall, 98 cases of patients who underwent surgery for penile prosthesis placements between the years 2005 and 2013 were reported by the ACS-NSQIP affiliated hospitals. The median age was 65 years (interquartile range, 58–70 years). The overall 30-day complication rate was 11.3% (n=11); 5 of the 11 complications were infectious in etiology, and three were a postoperative blood transfusion event. The median LOS was 1 day. One (1.0%) patient needed to return to the operating room, two patients (2.6%) were readmitted and there was one (1.0%) death within 30 days of the original surgery. Conclusions Surgery for penile prosthesis appears to be a safe operation despite the routinely advanced age of the patients requiring it. Complications in the immediate postoperative setting are usually infectious. This data can be used in the clinical setting for a more informed patient-physician discussion and patient expectation management.

Abstract
PURPOSE We investigated the impact of surgeon annual case volume on reoperation rates after inflatable penile prosthesis surgery. MATERIALS AND METHODS The New York Statewide Planning and Research Cooperative System database was queried for inflatable penile prosthesis cases from 1995 to 2014. Multivariate proportional hazards regression was performed to estimate the impact of surgeon annual case volume on inflatable penile prosthesis reoperation rates. We stratified our analysis by indication for reoperation to determine if surgeon volume had a similar effect on infectious and noninfectious complications. RESULTS A total of 14,969 men underwent inflatable penile prosthesis insertion. Median followup was 95.1 months (range 0.5 to 226.7) from the time of implant. The rates of overall reoperation, reoperation for infection and reoperation for noninfectious complications were 6.4%, 2.5% and 3.9%, respectively. Implants placed by lower volume implanters were more likely to require reoperation for infection but not for noninfectious complications. Multivariable analysis demonstrated that compared with patients treated by surgeons in the highest quartile of annual case volume (more than 31 cases per year), patients treated by surgeons in the lowest (0 to 2 cases per year), second (3 to 7 cases per year) and third (8 to 31 cases per year) annual case volume quartiles were 2.5 (p <0.001), 2.4 (p <0.001) and 2.1 (p=0.01) times more likely to require reoperation for inflatable penile prosthesis infection, respectively. CONCLUSIONS Patients treated by higher volume implanters are less likely to require reoperation after inflatable penile prosthesis insertion than those treated by lower volume surgeons. This trend appears to be driven by associations between surgeon volume and the risk of prosthesis infection.

Abstract
Inflatable penile prostheses are a common treatment for erectile dysfunction that is unresponsive to less-invasive measures. Complications can arise at the time of the placement of the prosthesis or at a later date. Complications may be related to infection and/or mechanical failure of one or more of the prosthesis components including cylinder, reservoir, pump, and tubing. Mechanical failure includes kinking, migration, and aneurysmal dilation of the cylinder, erosion of the tunica albuginea of the corpora cavernosum by the cylinder, disconnection of the tubing, and migration of the reservoir. MRI of the entire components with the cylinders in both flaccid and inflated states is the best imaging modality available to image patients with suspected implant complications.
