Review
BACKGROUND
The minimally invasive infrapubic approach (MIIA) for inflatable penile prosthesis (IPP) placement has shown favorable peri-operative safety and efficacy profile, but scarce data exist on long-term follow-up.
OBJECTIVES
We investigated the safety and efficacy of IPP implantation via the MIIA after a minimum 5-year follow-up.
MATERIALS AND METHODS
We identified data of implanted patients prospectively included in our institutional database. Complications and functional outcomes were assessed by using validated tools. Specifically, quality of life and patient satisfaction were evaluated by the Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) questionnaire. Kaplan-Meier method was used to analyze IPP survival (defined as a working IPP).
RESULTS
Overall, 67 patients implanted by MIIA with a median (IQR) age of 64 years (61-70) were included. The median (IQR) follow-up duration was 71 months (63-80). Fifteen (22%) patients experienced complications: minor (Clavien ≤2) events included changes in penile sensitivity (n = 1; 1.5%), orgasmic dysfunction (n = 1; 1.5%), pain (n = 5; 7%), urinary tract infection (n = 2; 3%), and chronic discomfort (n = 1; 1.5%); major (Clavien 3) complications were represented by mechanical failure (n = 3; 4.5%), IPP infection (n = 1; 1.5%), and cylinder protrusion (n = 1; 1.5%). The estimated IPP survival was 94% (95% CI, 91.4-96.6), 92.5% (95% CI, 89.7-95.3), and 92.5% (95% CI, 89.7-95.3) at 3, 5, and 7 years after implantation, respectively. In patients using the device at follow-up (n = 61; 91%), median (IQR) scores for QoLSPP domains demonstrated favorable functional outcomes and patient satisfaction: functional 21 (19-23), personal 16 (15-18), relational 14 (12-15), and social 12 (11-14).
DISCUSSION AND CONCLUSION
This study represents the longest follow-up using validated tools to assess the outcomes of IPP implantation via MIIA so far. IPP placement via MIIA confirms to be safe and to offer high satisfaction to both patients and partners at mid-term evaluation.

INTRODUCTION
The objective of this study was to assess the rates of surgical shunting and prosthesis placement for acute ischemic priapism using a large multi-institutional claims database.
METHODS
A US claims database network (TriNetX Diamond Network) was queried from 2010 to 2020. We constructed a cohort of men ages ≥ 16 years who (1) had a diagnosis of priapism and (2) underwent an irrigation of the corpora cavernosa for priapism. We assessed the number of men who then had a surgical penile shunt or penile prosthesis placement. Demographics, time to surgical procedure, and order of procedures were collected.
RESULTS
A total of 6392 men were identified with the diagnosis of priapism and the procedure of corpora cavernosal irrigation. Of these men, 693 (11%) proceeded to surgical shunt. One hundred forty-four men (2%) underwent initial penile prosthesis placement. Of the men undergoing initial penile prosthesis, only 17 of 144 (12%) cases occurred within the first month of corpora cavernosal irrigation. Finally, when assessing choice of initial shunts vs initial penile prosthesis before and after 2015, overall rates of initial shunt (10.0% vs 8.5%, < .0001) and initial prosthesis (3.1% vs 2.1%, < .0001) were lower after 2015 when compared with rates prior to 2015.
CONCLUSIONS
In this US claims-based analysis of men presenting with ischemic priapism and treated with initial irrigation, a small percentage (11%) of men went on to receive surgical shunting, and only 2% received an initial prosthesis. Men receiving initial prostheses were more likely to have more comorbidities, and overall surgical management of priapism has decreased over time.

The purpose of this investigation was to examine the timing of penile prosthesis infection management by different responsible organisms. A retrospective cohort study was performed of patients who underwent penile prosthesis salvage or explant procedures due to a suspected infection between 2001 and 2018. The cohort consisted of 216 patients from 33 different facilities and six countries. The most common primary organisms responsible for device infections included, Gram-positives (31.5%), no growth cultures (30.6%), Gram-negatives (22.2%), fungal (11.6%), and anaerobic organisms (4.2%). Overall, median time to infection was 1.8 (interquartile range [IQR]: 1.0-3.0) months for all patients. Median time to infection management was similar between responsible organisms: 1.0 (IQR: 1.0-2.3) months for Gram-negatives and 2 months for Gram-positives (IQR: 1.0-1.4), fungal (IQR: 1.0-5.0), anaerobes (IQR: 1.0-2.5), and no growth cultures (IQR: 1.0-3.0, p = 0.56). Median time to infection management was significantly shorter among patients who received aminoglycoside/vancomycin prophylaxis (1.5 months, IQR: 1.0-2.5, p < 0.01) compared to other antibiotic groups. Median time to infection management was significantly longer for patients managed with a three-piece inflatable implant salvage procedure (2.8 months, IQR: 1.0-5.0, p = 0.02) compared to other salvage procedures. Conventional wisdom surrounding early versus late penile prosthesis infections should largely be abandoned. More than half of penile prosthesis infections are surgically managed within 2 months of initial device placement.

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.

BACKGROUND
Sleep quality and duration have been investigated for their association with health. Insomnia affects up to one-third of adults and may impact male erectile function. In addition, medical treatments for insomnia (many of which are sedatives) may also affect erectile quality.
OBJECTIVE
To investigate the association of erectile dysfunction (ED) in patients diagnosed with and treated for insomnia.
DESIGN, SETTING, AND PARTICIPANTS
We utilized the IBM MarketScan (2007-2016) Commercial and Medicare Supplemental Databases (v 2.0). Age- and enrollment-matched controls were selected among patients without insomnia diagnosis or treatment.
OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS
Cox proportional hazard models were used to estimate the risk of incident ED (ie, diagnosis alone, or diagnosis and treatment with phosphodiesterase-5 inhibitors [PDE5i], intracavernous injection (ICI)/urethral suppositories, and penile prosthesis) after the diagnosis or treatment of insomnia while adjusting for relevant comorbidities.
RESULTS AND LIMITATIONS
In total, 539 109 men with an insomnia diagnosis were identified. Of these men, 356 575 were also medically treated for insomnia. The mean (±standard deviation) follow-up times for patients diagnosed with insomnia and those diagnosed with and treated for insomnia were 2.8 ± 1.6 and 3.1 ± 1.8 yr, respectively. Men with insomnia were more commonly smokers and had a higher number of office visits and comorbidities than controls (p < 0.001). On an adjusted analysis, both untreated and treated insomnia were associated with increased risks of ED diagnosis (hazard ratio or HR [95% confidence interval {CI}]: 1.58 [1.54-1.62] and 1.66 [1.64-1.69], respectively; p < 0.001). Similarly, men with treated insomnia had a higher risk of having ED treated with PDE5i (HR [95% CI]: 1.52 [1.49-1.55]; p < 0.001) and ICI (HR [95% CI]: 1.32 [1.14-1.54]; p < 0.001) when compared with controls. A limitation of this study was that a lack of granularity regarding patient clinical characteristics (eg, severity of disease, laboratory data, etc.) is inherent to insurance claims data. In addition, the follow-up was limited and may affect associations at longer time points.
CONCLUSIONS
In the current report, a consistent association between insomnia and ED diagnosis was identified. Men diagnosed with insomnia only were found to have a higher risk of developing ED. Moreover, men with pharmacological insomnia treatments were more often prescribed treatments for ED. Given the prevalence of insomnia, future studies are warranted to delineate the association of insomnia and its treatment with erectile function.
PATIENT SUMMARY
Insomnia affects up to one-third of adults and impact male erectile function. Men only diagnosed with insomnia were found to have a higher risk of developing erectile dysfunction (ED). Moreover, men with pharmacological insomnia treatments were more often prescribed treatments for ED.

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.

Review
BACKGROUND
The salvage procedure for infected penile implants (IPs) has been a subject of interest since its inception in the late 1980s, yet its widespread adoption remains limited. The aim of this study was to realize a systematic literature review to provide a comprehensive analysis of salvage techniques for IPs and assess their efficacy, specifically focusing on functional success.
METHODS
A systematic literature review was conducted using PubMed, employing Mesh terms related to penile prosthesis, penile implant, infection, and salvage procedures. Articles in French or English were considered for the final analysis, with exclusion of literature reviews.
RESULTS
Fifteen articles detailing various salvage techniques for IPs were identified. Mulcahy's initial technique was described in 1996, and consisted of complete removal of infected components, extensive lavage, and subsequent replacement with a similar implant. Success rates ranged from 80% to 100%, with emerging trends favoring the use of malleable implants during salvage. Unfortunately, functional data remained limited. When salvage penile prosthesis placement involved a malleable prosthesis, between 20% and 33% of patients underwent conversion to hydraulic prosthesis.
CONCLUSION
The salvage procedure for infected penile implants is a reliable method, with success rates surpassing 80%. The need for comparative studies assessing the type of implant used during salvage is required to tailor conservative management strategies for optimal patient outcomes. Finally, few data have been published regarding subsequent conversions from malleable penile implants to hydraulic penile implants after salvage.

Like all surgeries, penile prosthesis implantation (PPI) has the potential for both postoperative complications and suboptimal patient satisfaction. In order to assess risk factors for poor satisfaction, we reviewed patients who had been prospectively recruited in a national multi-institutional registry of penile prostheses procedures (INSIST-ED) from 2014 to 20121. Patient baseline characteristics and postoperative complications were recorded. The primary endpoint of this study was unfavorable outcomes after inflatable PPI, defined as significant postoperative complications (Clavien-Dindo ≥2) and/or Sexuality with Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) scores below the 10th percentile. A total of 256 patients were included in the study. The median age was 60 years (IQR 56-67). The most common cause of erectile dysfunction (ED) was organic (42.2%), followed by pelvic surgery/radiotherapy (39.8%) and Peyronie's disease (18.0%). Postoperative complications were recorded in 9.6%. High-grade complications (Clavien ≥2) occurred in 4.7%. At 1-year follow-up, the median QoLSPP total score was 71 (IQR 65-76). In all, 14.8% of patients were classified as having experienced unfavorable outcomes because of significant postoperative complications and/or QoLSPP scores below the 10th percentile. Logistic regression analysis demonstrated patient age to be non-linearly associated with the risk of experiencing unfavorable outcomes. A U-shaped correlation showed a lower risk for younger and older patients and a higher risk for middle-aged men. ED etiology and surgical volume were not associated with PPI outcomes. Physicians should, therefore, be aware that middle-aged men may be at higher risk of being unsatisfied following PPI compared to both younger and older patients.

Men with erectile dysfunction (ED) have high patient satisfaction after placement of inflatable penile prostheses (IPP). The impact on satisfaction and quality of life has never been studied in men who have sex with men (MSM). This study sought to assess the satisfaction rates and quality of life of MSM after placement of IPP for ED. This study was a multi-institutional, retrospective study that enrolled adult men who self-identified as MSM and underwent IPP placement. Two questionnaires were administered at one time point post-operatively, the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), and the Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) questionnaire. Results of these questionnaires were analyzed with descriptive statistics. Forty-nine MSM were assessed retrospectively with median age of 62 years with average follow-up of 15.2 months. Median EDITS score was 93.2/100 (range, 70.5-100). Median overall QoLSPP score was 72/80 (58-79), with median scores of 22/25 (16-25), 19/20 (13-20), 18/20 (12-20), and 14/15 (9-15), for the functional, personal, relational, and social domains respectively. Overall, MSM report high satisfaction rates and quality of life after IPP placement. A better understanding of the needs and demands of this patient population may lead to improved patient satisfaction and quality of life.

Review
Surgical treatments for ischemic priapism (IP) include shunts or penile implants. Non-ischemic priapism (NIP) is usually the result of penile/perineal trauma causing an arterial fistula and embolisation may be required. We conducted a systematic review on behalf of the EAU Sexual and Reproductive health Guidelines panel to analyse the available evidence on efficacy and safety of surgical modalities for IP and NIP. Outcomes were priapism resolution, sexual function and adverse events following surgery. Overall, 63 studies (n = 923) met inclusion criteria up to September 2021. For IP (n = 702), surgery comprised distal (n = 274), proximal shunts (n = 209) and penile prostheses (n = 194). Resolution occurred in 18.7-100% for distal, 5.7-100% for proximal shunts and 100% for penile prostheses. Potency rate was 20-100% for distal, 11.1-77.2% for proximal shunts, and 26.3-100% for penile prostheses, respectively. Patient satisfaction was 60-100% following penile prostheses implantation. Complications were 0-42.5% for shunts and 0-13.6% for IPP. For NIP (n = 221), embolisation success was 85.7-100% and potency 80-100%. The majority of studies were retrospective cohort studies. Risk of bias was high. Overall, surgical shunts have acceptable success rates in IP. Proximal/venous shunts should be abandoned due to morbidity/ED rates. In IP > 48 h, best outcomes are seen with penile prostheses implantation. Embolisation is the mainstay technique for NIP with high resolution rates and adequate erectile function.
