INTRODUCTION
Penile modeling to correct the penile curvature in Peyronie's disease (PD) may be achieved manually (intra-operatively or post-injection) or by using assisted devices (penile traction, vacuum device, or penile prosthesis).
OBJECTIVES
To evaluate the efficacy, safety, and satisfaction associated with penile modeling in patients with PD.
METHODS
A PROSPERO registered (CRD42021241729) systematic search in MEDLINE and Cochrane Library was done following PRISMA. PICO: Studies were deemed eligible if they assessed patients with PD (P) undergoing modeling procedures (I) with or without a comparative group(C) evaluating the efficacy, safety, or patient satisfaction (O). Retrospective and prospective primary studies were included. The primary outcome measure is the change in penile curvature after modeling. The secondary outcome measures are the change in stretched penile length, adverse events, and patient satisfaction after modeling.
RESULTS
A total of 23 studies, involving 1,238 patients were included. Most studies (13, 56.5%) evaluated penile traction therapy. The studies were of low and intermediate quality (mean Newcastle-Ottawa Scale score of 5.7 and mean Jadad score of 3.3) with a mean level of evidence of 3.4. The mean penile curvature at baseline was between 31 and 80.8 degrees. Nine (39.1%) studies found a significant improvement (P < .05) of penile curvature after penile modeling, ranging between 11.7, and 37.2 degrees. An increase in mean stretched penile length was reported in 7 (30.4%) articles, varying between 0.4, and 1.8 cm. Serious complications such as penile prosthesis malfunctions (3.3-11.1%) and urethral injuries (2.9%) were only reported for intra-operative manual modeling.
CONCLUSION
Although individual studies have noted improvement in penile curvature and stretched penile length, specific recommendations regarding penile modeling in PD cannot be provided due to limited evidence available. Further RCTs with adequate sample size, validated assessment tools, and longer follow-up are needed. Krishnappa P, Manfredi C, Sinha M et al.

INTRODUCTION
Penile prosthesis implantation (PPI), performed with or without adjunct straightening techniques, is one of the available surgical options in cases of Peyronie's disease (PD) with concomitant erectile dysfunction (ED). The aim of the study was to systematically identify and evaluate evidence regarding IPP in patients with PD and ED.
EVIDENCE ACQUISITION
Using Cochrane's methodological recommendations on systematic reviews, we conducted a systematic review of the literature on clinical research regarding the use of PPI, alone or in combination with any straightening maneuvers in the treatment of patients with PD and ED. The search was carried until January 2020. We included studies in English language with primary population patients with PD and ED who underwent IPP with the intent to treat the PD. All studies that were not original clinical research articles, reported insufficient data or included fewer than 5 patients were excluded from the final analysis.
EVIDENCE SYNTHESIS
In total 43 clinical articles with more than 2000 patients (N.=2143) investigating the effects of penile prosthesis implantation (PPI) for the treatment of PD with or without ED were included in the study. Depending on the severity of the penile curvature, additional penile deformities (i.e. hourglass deformity), penile length, prior operations and surgeons experience, 6 main categories of surgical techniques of PPI for penile straightening and treatment of PD were identified: PPI only, PPI with modelling of the penis, PPI with plication of the penis on the convex side of the curvature, PPI with plaque incision(s), PPI with plaque incision/excision plus grafting and PPI with grafting and penile lengthening.
CONCLUSIONS
Overall, patients with PD and ED can expect excellent outcomes with PPI against a minimal risk of side effects. No definite conclusions can be made regarding which technique is superior.

Meta-Analysis
INTRODUCTION
Refractory priapism, characterized by persistent and prolonged painful erections despite initial treatment maneuvers, can significantly impair erectile function secondary to ischemia-induced corporal tissue fibrosis. These patients will likely require subsequent penile prosthesis (PP) surgery to regain sexual activity, yet consensus regarding the optimal timing of implantation remains lacking.
OBJECTIVES
To evaluate and compare the clinical outcomes associated with early vs delayed PP implantation in individuals with priapism-induced erectile dysfunction (ED).
METHODS
We included studies that focused on refractory priapism leading to ED and its management with PP implantation. We assessed cohort study bias with a risk-of-bias tool and case series bias with the modified Newcastle-Ottawa Scale. Pooled odds ratios (ORs) were calculated by a fixed-effect model.
RESULTS
We included 9 studies, comprising 4 cohort studies and 5 case series, involving a total of 278 patients. Total complications were higher in the delayed group (OR, 4.16; 95% CI, 2.77-6.26). Fibrosis was significantly more pronounced in the delayed group (OR, 118.18; 95% CI, 20.06-696.32). The odds of erosion, infections, and penile injury did not show statistically significant differences between the groups (OR, 2.52 [95% CI, 0.67-9.49], 0.89 [0.38-2.10], 1.83 [0.79-4.26], respectively). Patients' satisfaction resulted in a pooled OR of 0.15 (95% CI, 0.04-0.49) in favor of the early PP insertion group.
CONCLUSION
The results from this study favor an early approach to ED (within 30 days) following ischemic priapism. However, it is important to consider patients' preferences, values, and psychological factors to make an informed decision.

Review
A phalloplasty is a complex genital reconstruction procedure of creating a neophallus. Several techniques to create a neophallus are described, based on different vascularized flaps, and each of them has its advantages and drawbacks. The aim of this study is to present musculocutaneous latissimus dorsi (MLD) flap as a viable option for total phalloplasty, with an interest in clinical outcomes and complications. A comprehensive literature review of all available reports about MLD flap phalloplasty was made. The following keywords were used on PubMed: latissimus dorsi musculocutaneous/myocutaneous free flap and phalloplasty. Research criteria revealed five articles and the results of 182 patients were analyzed. A total number of the patients, indications, operative technique, follow-up period, postoperative results, and complications were presented. In conclusion, MLD free flap presents a good choice for phalloplasty providing sufficient amount of tissue for safe implantation of penile prosthesis and successful penetrative sexual intercourse. The erogenous sensitivity is preserved with clitoris or glans penis incorporated into the base of the neophallus, and voiding in a standing position is achievable after urethral reconstruction. The main drawback is the lack of tactile sensation of the neophallus and the significant advantage is a well-concealed donor site.

Review
There are only two three-piece inflatable penile prostheses (IPP) available to patients in the American market: the AMS (American Medical Systems) 700 series (Boston Scientific, Massachusetts) and the Coloplast Titan® series (Coloplast, Minnesota), and data comparing the two are scant. The aim of our study was to summarize the current scientific evidence comparing the two. A systematic literature review was conducted on PubMed. A 10-year filter was placed to include only studies published after Coloplast launched the Titan Touch® release pump. Eligibility criteria included articles discussing specifically the AMS 700 and Coloplast Titan® models. Further searches for studies on patient/partner satisfaction were conducted. Abstracts were reviewed to include studies focusing specifically on the models we are studying and studies on patient satisfaction using the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire. The Coloplast device demonstrated slightly greater resistance to the stimulated forces of penetration and gravity. Coloplast implants coated with vancomycin/gentamicin had the highest infection rate followed by the AMS penile prosthesis and the rifampin/gentamicin coating had the lowest infection rate. Prosthesis durability and survival were similar between both brands. Overall satisfaction was high but comparisons are inconsistent. The literature is inconclusive about which device is superior. We suggest randomized, multicenter, prospective studies to help further elucidate the highlights of each product.

INTRODUCTION
Retained reservoirs can be a complex problem for clinicians who manage patients with inflatable penile prostheses (IPPs). Although the general safety of retained reservoirs is well documented, data on the long-term outcomes of these foreign bodies is scarce. In recent years, complications associated with retained reservoirs and the subsequent management of these cases have become more recognized.
AIM
To review, analyze, and summarize the concept of retained reservoirs and their associated complications with retained reservoirs and to provide a guide for management of complicated retained reservoir patients.
METHODS
We performed a systematic review of the PubMed database on retained reservoir-related complications and perioperative management.
MAIN OUTCOME MEASURES
We reviewed all publications that detailed complications associated specifically with retained penile prosthesis reservoirs and analyzed perioperative strategies used by providers. Any publication outlining IPP reservoir-related complication(s) stemming from a reservoir that was part of a functioning IPP was excluded.
RESULTS
Although the risk is low, serious complications can and do arise from retained reservoirs. To properly manage these patients, clinicians must have knowledge of the prosthetic history and maintain a low threshold for obtaining cross-sectional imaging. By using methodical perioperative planning, the need for reintervention in patients with complications can be reduced, and improved surgical outcomes can be achieved.
CONCLUSIONS
The management of retained reservoirs and their complications can be a clinical challenge for prosthetics providers. As such, more data regarding long-term outcomes and management strategies of retained reservoirs are required to better serve this subset of patients with prostheses.

Review
INTRODUCTION
Penile prosthesis implantation has emerged as a definitive treatment to restore sexual function to the motivated man with erectile dysfunction. Substantial improvements in the design of inflatable devices have been made since they first became available more than four decades ago.
AIM
To review the history of the penile prosthesis, the indications, preoperative evaluation, and patient and partner satisfaction. The current approaches to addressing intra- and postoperative complications, provide an understanding of prosthesis infection, and placement of these devices will be reviewed.
METHODS
A committee of worldwide experts in this field was assembled during the 2015 International Consultation on Sexual Medicine (ICSM) and performed a systematic review of the peer-reviewed published medical literature pertaining to penile prosthesis. Particular attention was given to higher level trials when available. Recommendations are based upon the Oxford Criteria.
MAIN OUTCOME MEASURES
Unfortunately there is limited level 1 and 2 evidence, and where expert opinion was utilized, the decision was unanimous within the committee with a goal of presenting a clinically relevant guideline pertaining to penile prostheses.
RESULTS
Penile prosthesis has undergone an evolution over the past 40 years resulting in a more effective and reliable treatment for advanced erectile dysfunction not responding to less invasive methods including oral treatment with PDE5 inhibitors, vacuum erection device, and intracorporal injection therapy. It should be considered an appropriate treatment option for the man who wishes to restore erectile function and who understands the potential risk of mechanical failure and infection, both of which are less common now as a result of improvements made in device design as well as surgical protocols adhered to in the operating room. Patients must be clearly informed of the risks associated with penile prosthesis including mechanical failure, infection, shortening of the penis, change in sensation and configuration of the penis, as well as injury to local structures. Intraoperative complications are unusual but do occur and can usually be addressed intraoperatively to allow placement of the device at the time of initial surgery. Postoperative complications may also be addressed when they occur but may require more advanced reconstructive surgical techniques. Men with Peyronie's disease, corporal fibrosis due to infection, trauma, prior prosthesis explantation, priapism, and men who have undergone construction of a neophallus may require additional advanced maneuvers to obtain optimum results with a penile prosthesis.
CONCLUSION
Penile prosthesis remains as an important, viable, and effective treatment for male erectile dysfunction that does not respond to other less invasive approaches or when these approaches are contraindicated or not acceptable to the patient. These devices provide the patient with the ability to engage in penetrative sexual activity without interfering with urination, ejaculation, sensation, or orgasm. Although mechanical failure can occur, the current devices are more reliable as a result of design modifications. Infection remains the most dreaded complication but since the introduction of antibiotic and hydrophilic coatings, infection is less common. Overall, patient and partner satisfaction appear to be reasonably high when a penile prosthesis is used to restore erectile function.

Review
The term scrotoplasty embraces several techniques which aim to restore a normal scrotal appearance and function. We provide here a quick reference tool to allow the urologist to select the appropriate surgical strategy among the several available options. A comprehensive research was carried out on MEDLINE/PubMed to identify relevant studies concerning this topic, including a range of key words, e.g., scrotoplasty, ventral phalloplasty, scrotal reconstruction, scrotomegaly, penoscrotal web, scrotal lifting, scrotal reduction, scrotectomy, scrotal lymphoedema. Scrotal skin defects may be related with Fournier's gangrene, traumatic events, and surgery for genital cancers or peno-scrotal lymphoedema. The reconstructive management of these conditions is relatively reproducible in the hands of experienced urologists, if aware of the basics of scrotal surgery. Primary tension-free wound closure and local pedicled flaps typically allow optimal surgical outcomes for repairing most of these scrotal defects, with split-thickness skin grafts (STSGs) and/or distant flaps being required only when dealing with extensive skin losses. The demand for genitals' aesthetic surgery among adults is on the increase recently. Although the scientific evidence regarding this topic is scarce, reduction scrotoplasty and peno-scrotal webbing correction techniques are easy, safe and effective solutions to improve genital cosmesis, being carried out in isolation or in combination with penile prosthesis implantation. More robust scientific evidence is needed to achieve a uniformed consensus regarding the optimal surgical management in this broad field, and surgical innovation should continue to refine current reconstructive techniques.

CONTEXT
The genesis of neurogenic sexual dysfunction (NSD) can be central, peripheral, or both. The correct stratification of the level of sexual dysfunction allows the clinician to choose the best type of treatment, in order to reduce sexual complaints.
OBJECTIVE
The aim of our review is to focus on the management of NSD due to central nervous system disorders and peripheral neuropathy.
EVIDENCE ACQUISITION
A systematic review of the English-language literature was completed until July 2019 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The following terms were included: [(neurogenic sexual dysfunction) OR neurogenic erectile dysfunction)] AND (treatment OR management). An Excel file was created respecting the following criteria: participants, interventions, comparators, outcomes, and study design (PICOS).
EVIDENCE SYNTHESIS
Overall, from 505 identified records, 52 full-text articles were assessed for eligibility. Finally, 46 original researches were included in quantitative analysis.
CONCLUSIONS
The phosphodiesterase type 5 inhibitors sildenafil, tadalafil, and vardenafil were proved to be effective and safe in first-line therapy of erectile dysfunction caused by neurogenic disorders. In addition, intracavernous injections of prostaglandin E1, papaverine, or phentolamine and vacuum systems have been a mainstay of second-line treatment for NSD, extremely successful in the spinal cord injury population. Surgical therapy via penile prosthesis implantation remains a viable alternative as a third-line approach and may also be utilised to assist men with bladder management, despite higher complication rates of infections. Despite poor evidence, a better understanding of female sexual dysfunction due to neurological complaints is needed, in order to find more efficacious therapies for intercourse and orgasmic phase. Further prospective studies are required to better clarify the more successful treatment in improving sexual function and quality of life of these patients.
PATIENT SUMMARY
Management of neurogenic sexual dysfunction includes phosphodiesterase type 5 inhibitors, intracavernous injections/vacuum devices, and penile prosthesis implantation. Female sexual dysfunction due to neurological disease needs to be better investigated.

Meta-Analysis Review
INTRODUCTION
The efficacy, safety, and postoperative outcomes of synchronous surgery for concomitant erectile dysfunction (ED) and stress urinary incontinence (SUI) remain unclear.
OBJECTIVES
We performed a systematic review and meta-analysis to evaluate the available synchronous surgical approaches for concomitant ED and SUI and to assess the reoperation rates compared to asynchronous surgery and surgery only for ED or SUI.
METHODS
We searched PubMed, Cochrane Library, and Embase databases until June 2022 for relevant studies. Based on data availability, we performed a meta-analysis of odds ratios (ORs) comparing reoperation rates after synchronous surgery in patients with concomitant ED and SUI versus asynchronous surgery, as well as surgery solely for ED or SUI (PROSPERO: CRD42022326941).
RESULTS
We included 18 studies in the systematic review (16,517 patients) and 5 in the meta-analysis. Comparing synchronous implantation of penile prosthesis and artificial urinary sphincter (AUS) versus asynchronous surgery, no statistically significant differences were observed in the reoperation rates [OR:0.98, 95% confidence interval (CI): 0.52-1.84, I:0%). Comparing synchronous implantation of both penile prosthesis and AUS versus implantation of only a penile prosthesis or an AUS, combined surgery was associated with higher reoperation rates (OR:2.02, 95%CI: 1.29-3.16, I:36% and OR:1.7, 95%CI: 1.25-2.32, I:0%, respectively). Synchronous surgery led to high satisfaction rates and significant improvement in ED and SUI. Evidence for the combination of penile prosthesis with a male sling or the ProACT device is low, but data suggests it may be safe and effective. The synchronous placement of a Mini-Jupette sling and penile prosthesis represents a promising treatment modality for the correction of ED and mild SUI and/or climacturia.
CONCLUSIONS
Synchronous penile prosthesis and AUS implantation appears safe and effective in patients with severe ED and SUI. Further high-quality studies are mandatory to strengthen the current scarce evidence for synchronous surgery in patients with ED and SUI. Pyrgidis N, Barham DW, Hammad M, et al.
