Combination of pregabalin and Amitriptyline in management of chronic idiopathic pain following penile prosthesis implantation: a pilot study

BACKGROUND

Chronic post-penile prosthesis pain is de novo pain persisting > 2 months post-operatively. This pain is inadequately reported, poorly understood and undermanaged. The purpose of this current pilot study was to improvise a medical approach to alleviate the condition and assess the combination of Pregabalin and Amitriptyline in its management.

RESULTS

The study enrolled 9 patients complaining of idiopathic penile, pelvic, or scrotal pain persisting > 2 months after penile prosthesis implantation. Patients were prescribed pregabalin 75mg/12h (escalated after 1 week to 150mg/12h upon demand) and Amitriptyline 25mg once daily for 3 months. The pain was reassessed after 10, 30 and 100 days. The dose of pregabalin required and the side effects of the medication were noted. Findings revealed a significant decrease in pain duration (p = 0.007), frequency (p < 0.001), and intensity (p < 0.001); in glanular (p = 0.008), shaft pain (p = 0.046) but not scrotal (p = 0.112). Moreover, a significant decrease was found in sharp pain (p = 0.003) and pain aggravated by touch (p = 0.008) but not aching pain (p = 0.277). Additionally, significant improvement was reported in QoL (p < 0.001) and dose escalation of pregabalin to 150mg/12h was required in only 1 case (11%).

CONCLUSION

The combination of pregabalin and amitriptyline is very effective in the management of chronic idiopathic pain following penile prosthesis implantation. However, due to the ambiguity and lack of reporting of the condition, we recommend a multicentric contribution to acknowledge the condition, and weigh its prevalence accurately, whilst evaluating the efficacy of our approach. This study received ethical approval from Ain Shams University Research Ethics Committee (REC) FWA 000017585, on 04/13/2023 (REC-FMASU@med.asu.edu.eg).

An evaluation of three validated comorbidity indices to predict short-term postoperative outcomes after prosthetic urologic surgery

PURPOSE

Commonly used comorbidity indices include the Charlson Comorbidity Index (CCI), Elixhauser/Van Walraven Index (VWI), and modified frailty index (mFI). This study evaluates whether these indices predict postoperative readmissions and complications after inflatable penile prosthesis (IPP) and artificial urinary sphincter (AUS) placement.

METHODS

We identified adult males who underwent IPP or AUS placement using the State Inpatient and State Ambulatory Surgery and Services Databases for Florida (2010-2015) and California (2010-2011). CCI, VWI, and mFI scores were calculated for each patient. We extracted 30-day emergency department services, 30-day readmissions, 90-day device complications (e.g., removal, replacement, or infection), and 90-day postoperative complications (excluding device complications). Receiver-operating characteristic curves were constructed and areas under the curve (AUC) were compared between the indices using the VWI as the reference model. We considered an AUC < 0.7 to represent poor predictive power.

RESULTS

We identified 4242 IPP and 1190 AUS patients. All three indices had AUCs and 95% confidence intervals less than 0.70 for all outcomes following IPP and AUS placement making these indices poor predictors for postoperative outcomes. There were no significant differences in predicting 90-day postoperative complications between the VWI (AUC = 0.59, 95% CI [0.54-0.63]), CCI (AUC = 0.59, 95% CI [0.54-0.63], p = 0.99), and mFI (AUC = 0.60, 95% CI [0.55-0.66], p = 0.53) for IPPs and VWI (AUC = 0.54, 95% CI [0.47-0.61]), CCI (AUC = 0.50, 95% CI [0.43-0.57], p = 0.30), and mFI (AUC = 0.52, 95% CI [0.43-0.60], p = 0.56) for AUS placements.

CONCLUSION

All three comorbidity indices were poor predictors of readmissions and complications following urologic prosthetic surgeries. A better comorbidity index is needed for risk-stratification of patients undergoing these surgeries.

Satisfaction assessment study in patients (and their partners) with/without Peyronie's disease and penile prosthesis implantation

INTRODUCTION AND OBJECTIVE

Among the many treatments for erectile dysfunction, implantation of a penile prosthesis has been associated with high patient satisfaction rates. However, patients with coexistent Peyronie's disease (PD) and refractory erectile dysfunction and/or severe deformities may show different results. The aim of our study was to assess and to compare the level of satisfaction, with an inflatable penile prosthesis (IPP), in men with/without coexistent PD.

MATERIAL AND METHODS

A survey study based on a five-item satisfaction questionnaire was submitted to all those live patients implanted in the period 1992-2022 at our center (n = 570) and their partners. Ninety-two percent of implants were inflatable devices. Surgeries were mainly performed by two surgeons. The main outcome measure used was the level of patient and partner satisfaction with sexual intercourse after IPP.

RESULTS

Of the 570 eligible patients, 479 (84%) completed the survey (393 Non-PD: GROUP 1; 70 non-complex PD-Group 2; 16 complex PD). Eighty-six per cent of patients in Group 1 reported satisfactory sexual intercourse (very or moderately satisfied). Non-complex PD implanted patients (Group 2) reported a global 81% satisfactory sexual intercourse (very or moderately satisfied) (p > 0.05). However, when we evaluated the PD subgroup of patients with severe PD who require incision/excision/grafting at the time of implant (Group 3: n = 20), only 61% reported satisfactory sexual intercourse (p < 0.01) with predominance of moderately satisfied patients over very satisfied: 78% vs. 22%). Additionally, 84% (Group 1), 80% (Group 2) and 54% (Group 3) of partners reported satisfactory intercourses, respectively (p < 0.01). Overall, 84% of Group 1 implants and 79% of Group 2 reported that they would undergo the procedure again if the IPP failed (p > 0.05; ns). Only 50% of Group 3 patients would do it again. With regard to cosmetic aspects, 48% of the Group 3 implant reported penile shortness or soft glans as the main causes of their dissatisfaction. Only 2.4% of total PP patients expressed difficulty in manipulating the device.

CONCLUSION

The presence of PD alone may not impact PP patient and partner satisfaction, but patients with more severe baseline deformity who require incision/grafting may be less satisfied with outcomes including penile length and glans sensation.

Penile prosthesis in the medically complex patient: a narrative review

Background and Objective

Penile prosthesis surgery is considered a safe and effective treatment for patients with erectile dysfunction. Implantation in the medically complex patient can be a challenge. The benefits of treatment must outweigh the possible risks or complications. A description of possible problems and how to cope with them is given in this narrative review.

Methods

Literature search was performed in January 2023 using different search prompts in PubMed. These articles, excluding non-English and non-full text articles, were listed by the two authors and afterwards, the most relevant ones were included.

Key Content and Findings

This article is divided into five important topics. We evaluated different comorbidities such as spinal cord injury, diabetes mellitus and cardiovascular disease, in which preoperative work-up and counseling is of significant importance. A detailed description of these comorbidities and how to handle these can be found in each section. In addition to the preoperative aspect in organ transplant patients, problems during surgery can arise, e.g., with the reservoir placement. Similarly, in patients with previous pelvic surgery, an ectopic reservoir placement can prevent possible complications.

Conclusions

Preoperative diagnostics are crucial and prosthetic surgery should be done by an experienced high-volume surgeon with a diverse range of surgical techniques at his disposal.

Comparison of preoperative penile elastographic ultrasound findings and pathological tissue results of patients implemented with penile prosthesis

OBJECTIVE

Histopathological analysis of the relationship between penile elastography and erectile dysfunction.

MATERIAL AND METHOD

12 patients who applied to our clinic for erectile dysfunction in the last 1 year and accepted this study were included. Preoperative two-dimensional shear wave elastography imaging was performed in 12 patients and recorded in the Pascal (kPa) unit. Approximately 0.5 × 0.5 × 0.5 cm tissue samples were taken from the right and left cavernous tissue during penile prosthesis implantation operation. Tissue samples were sent to the pathology department. The percentage of the area covered by muscle fibers and elastic fibers in the corpus cavernosum was noted semi-quantitatively (ratio of muscle fibers and cavernous body elastic fiber score). All data obtained were compared with each other.

RESULTS

Cavernous body elastic fiber score data(Grouped Score 1, 2 and 3) and percentage of cavernous body muscle fibers data (Grouped %10, %20, %30… %100) were compared with Shear wave elastography data (kPa). The results were not statistically significant according to the Kruskal Wallis Test. Cavernous body elastic fiber score and the percentage of cavernous body muscle fibers were also compared, it was not statistically significant according to the Kruskal Wallis test and Spearman's correlation test.

CONCLUSIONS

Penile shear wave elastography can be used clinically to quantitatively assess the amount of smooth muscle cells and elastic fibers in the penis, but it deserves to be studied with a larger number of patients and a more specific interpretation of the pathology preparation.

A Systematic Review of Partner Satisfaction After Penile Prosthesis with Special Emphasis on LGBTQ + Populations

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.

Systematic review of the implantation of penile prosthesis in major ambulatory surgery

INTRODUCTION AND OBJECTIVE

Penile prosthesis (PP) implantation is an effective option for erectile dysfunction. Although initially PP surgery was carried out in an inpatient setting, there is a growing trend to implant PP as a major ambulatory surgery (MAS). This study aimed to perform a systematic review of the literature to identify available evidence of the implantation of PP under MAS setting and go carry out a comparison between MAS and inpatient procedures.

MATERIAL AND METHODS

PubMed, EMBASE, Cochrane Library and MEDES electronic databases and non-indexed supplements for scientific congresses were searched to identify articles related to the surgical implantation of PP in MAS up to February 2021. Key search terms included penile prosthesis, erectile dysfunction, ambulatory surgery, ambulatory care, and surgery.

RESULTS

Among 171 publications retrieved (51 PubMed, 73 EMBASE, 3 Cochrane, 2 using MEDES and 42 manual searching), 5 studies were finally selected. There were no significant differences between MAS or inpatient setting in terms of the type of device, surgical approach, or location of reservoir. Complication rates observed in both groups were similar. Implantation of PP in MAS was less expensive than inpatient surgery and was associated with acceptable patient satisfaction rates and adequate pain control.

CONCLUSIONS

Studies demonstrated that outpatient PP surgery can achieve similar outcomes in terms of safety and satisfaction to implantation of PP in the inpatient setting, while it could reduce costs and improve the efficiency. This research could support decision makers to extend PP surgery into the ambulatory setting.

Relationships between erectile dysfunction, prostate cancer treatment type and inflatable penile prosthesis implantation

PURPOSE

The prevalence of erectile dysfunction (ED) and the utilization of inflatable penile prosthesis (IPP) among prostate cancer patients are understudied. The aim of the study was to examine the relationships between ED, prostate cancer treatment type and IPP implantation in a national cohort.

MATERIALS AND METHODS

We identified a retrospective cohort of Surveillance, Epidemiology, and End Results (SEER)-Medicare patients diagnosed with locoregional prostate cancer between 2006 and 2011 and treated with surgery or radiation. Chi-square tests were used to detect significant differences in ED rates as well as use of IPP among the subset with ED. Multivariable logistic regression was used to examine factors associated with the use of IPP.

RESULTS

Among 31,233 patients in our cohort, 10,334 (33.1%) received prostatectomy and 20,899 (66.9%) received radiation. ED within 5 years was significantly more common in the prostatectomy group relative to those the radiation group (65.3% vs. 33.8%, p<0.001). In the subset of 13,812 patients with ED, the radiation group had greater median time to ED diagnosis compared to the prostatectomy group (346 vs. 133 days, p<0.001). IPP implantation was more frequent for prostatectomy patients than for radiation patients (3.6% vs. 1.4%, p<0.001). Cancer treatment type, race, and marital status were significantly associated with IPP utilization.

CONCLUSIONS

ED is highly prevalent among prostate cancer patients, and IPP implantation is be underutilized. ED rates, time to ED diagnosis and utilization of IPP differed significantly by prostate cancer treatment type.

Inflatable penile prosthesis reservoir placement-Are we ready for a paradigm change?

In 2002, Steve Wilson pioneered new procedures for alternative placement of reservoirs for inflatable prostheses in patients who have suffered damage to the space of Retzius following pelvic surgery or obliteration of the transversalis fascia by mesh hernia repair. Since then, surgical techniques and tools for ectopic reservoir placement have gradually gained acceptance to minimize palpability, and the risk of visceral and vascular lesions for high risk patients has been all but eliminated. Lockout valves and high submuscular placement techniques are now recommended, and reports of vascular, bowel or bladder injuries are uncommonly rare. While surgeons continue their search for safer and more effective placement methods, new skills and instruments are constantly being introduced to make recommendations to minimize complications and provide safety and functionality. Additional studies and comparisons of techniques are needed to achieve a consensus of best practice for reservoir placement solutions.

Prevention of Penile Prosthesis Infection

INTRODUCTION

Management protocols for treatment of severe erectile dysfunction have changed little in the last 20 years. Most algorithms consider penile prostheses as the last option of treatment in patients who have failed medical management. Despite multiple advances in current devices, prosthetic infection remains the most feared complication by implanting surgeons and patients. This report tries to make a compilation of the factors that can be impacted to prevent penile implant infections, and to make penile implantation a safer and more reliable way to solve an erection deficit.

PURPOSE OF REVIEW

List events related to the surgical act (pre-operative, intra-operative, and post-operative) that are related to the risk of infection to contextualize possible actions/measures used to avoid prosthetic infection.

RECENT FINDINGS

The impact of coated implants on reduction of infection rates. The recommendation to use chlorhexidine-based solutions over iodine solution for preoperative skin preps. Appears to be no difference in infection rates according to the approach chosen by the surgeon (infrapubic vs penoscrotal). The change in the microbial colonies that are colonizing implants in recent years are dramatic. Lack of evidence of which solutions to use for salvage or revision washout surgery: Chemical eradication or mechanical lavage cleansing?. Despite the importance of metabolic control in the literature, there is a disparity in exact glycemic values ​prior to the intervention in our literature. Factors such as preparation of the operative site, presence of comorbidities or previous surgeries, surgical time, or additional maneuvers during surgery can negatively impact the final result of penile prosthetic surgery.

Is There a Role for Antifungal Prophylaxis in Patients Undergoing Penile Prosthesis Surgery? A Systematic Review

OBJECTIVE

The aim of this study is to review the literature on the use of antifungal prophylaxis in penile prosthesis (PP) surgery and provide a summary on its efficacy as an adjunct to current prophylactic regimes in patients undergoing PP surgery.

MATERIALS AND METHODS

PubMed, Medline, and EMBASE databases were systematically searched up to May 2020. All included studies were analysed and the information extracted included author, title of study, year of publication, type of study, journal of publication, and main findings regarding post PP implantation fungal infections.

RESULTS

Nine relevant studies were included in this review, comprising retrospective single-centre studies and retrospective multicentre studies ranging from 2017 to 2020. Fungal infections were found responsible for 11.1% of all PP infections, with a greater risk in patients with diabetes, obesity, and from warmer climates. Current American Urological Association (AUA) and European Association of Urology (EAU) prophylaxis guidelines do not incorporate the use of antifungals. Trials of antifungal prophylaxis regimes combined with antibiotic prophylaxis have demonstrated a reduction in PP fungal infections.

CONCLUSIONS

Fungal infections represent a significant proportion of implant infections and therefore antifungal prophylaxis is warranted. Future studies comparing the efficacy of traditional antibiotic prophylaxis as set out by AUA/EAU with novel prophylaxis regimes including the addition of an antifungal may provide more definitive guidance on this issue. Until then antifungal prophylaxis in all patients undergoing PP procedures may provide a significant cost-effect benefit.

Erectile Dysfunction is a Modifiable Risk Factor for Major Depressive Disorder: Analysis of a Federated Research Network

BACKGROUND

Erectile dysfunction is one of many conditions associated with depression, but few studies exist to establish the risk of major depressive disorder (MDD) in the large population of men with erectile dysfunction, and it is unclear whether erectile dysfunction (ED) treatment is associated with decreased rates of MDD.

AIM

We determined the risk of major depressive disorder in men with erectile dysfunction and evaluated whether treatment of ED with phosphodiesterase-5 inhibitor or penile prosthesis is associated with a lower risk of developing major depressive disorder.

METHODS

We reviewed a large, retrospective, cohort that utilized electronic health record data collected by the TriNetX Research Network, a global federated database that provides healthcare data for analysis. We performed multiple comparisons: men with ED against men without ED; men with ED treated with phosphodiesterase-5 inhibitors against untreated ED patients, and of men with ED who received penile prosthesis against those who did not. We assessed major depressive disorder (ICD-10-CM F32-F33) as a primary outcome and used propensity score matching to control for ethnicity, race, type 2 diabetes mellitus (E11), essential hypertension (I10), acute myocardial infarction (I21), chronic ischemic heart disease (I25), cerebral infarction (I63), overweight and obesity (E66), personal history of nicotine (Z87.891), hypogonadism (E29.1), and alcohol related disorders (F10).

OUTCOMES

We assessed new diagnosis of major depressive disorder (F32-F33) within a 3-year time window following index event of ED diagnosis, visit to healthcare organization, or ED treatment with phosphodiesterase-5 inhibitor or penile prosthesis as the primary outcome.

RESULTS

ED was associated with major depressive disorder both before and after (OR 2.00, 95% CI 1.94-2.06) controlling for confounding variables through propensity score matching. Men who received ED therapies had lower rates of depression compared to those who did not, whether they were treated with phosphodiesterase-5 inhibitor (0.80, 0.77-0.83) or penile prosthesis (0.73, 0.60-0.89).

STRENGTHS AND LIMITATIONS

Strengths include a large sample size and robust statistical techniques. Limitations include lack of detailed information regarding clinical severity and socioeconomic factors.

CLINICAL IMPLICATIONS

Our findings indicate that clinicians should consider evaluating depressive symptoms among men with erectile dysfunction and counsel them regarding the risk of developing major depressive disorder.

CONCLUSIONS

Erectile dysfunction is associated with major depressive disorder, but treatment is associated with decreased rates of MDD. S Nackeeran, A Havanur, J Ory, et al.

Technological Advancements for Treating Erectile Dysfunction and Peyronie's Disease

Over the past decade, there have been several advancements in the technologies available to treatment erectile dysfunction and Peyronie's disease. Vacuum erection devices, penile traction devices, low-intensity extracorporeal shockwave therapy, and penile prosthesis surgery have evolved and are changing the way we treat men's health. Although significant improvements have been made, further work is needed to standardize treatment, create universal algorithms for technological applications, and simply their use.

Management of Priapism: 2021 Update

Priapism is defined as a persistent penile erection lasting more than 4 hours. Priapism is a rare condition but when present it requires prompt evaluation and definitive diagnosis. Priapism has 2 pathophysiologic subtypes: ischemic and nonischemic. Ischemic priapism accounts for a majority of cases reported. Ischemic priapism is a urologic emergency and requires intervention to alleviate pain and prevent irreversible damage to erectile tissues. This article highlights current guidelines and the contemporary literature on priapism.

Imaging review of penile pathologies encountered in the emergency department

While penile pathology is uncommon, prompt diagnosis and treatment of emergent and urgent penile pathology are necessary to prevent complications. This paper will review the imaging findings of the most common critical penile pathologies, including traumatic, vascular, infectious, foreign body-related, and urethral pathology, in addition to penile prosthesis complications. Each entity will be discussed in the context of presentation and treatment and complications of each pathology will be discussed.

Urethral instillation of chlorhexidine gel is an effective method of sterilisation

Objective: To examine the effectiveness of preoperative urethral sterilisation with chlorhexidine gel in rendering the urethra as sterile as the skin of the genital area, with the skin sterilised as per the International Society for Sexual Medicine guidelines for penile prosthesis implantation. Patients and methods: A total of 111 male patients undergoing sterile andrological surgical procedures were divided into a control group (N = 61) and a chlorhexidine gel group (N = 50). Patients in the chlorhexidine group received urethral instillation with 6 mL of chlorhexidine preoperatively and on table. Patients from both groups received on-table skin preparation using povidone iodine and chlorhexidine povidone iodine. At the end of surgery, swabs were obtained from urethra and the penile skin. Skin and urethral swabs were compared for bacterial colonisation by culture and sensitivity. Results: Of the 111 patients, 16 had urethral colonisation and 10 had skin contamination, and they were all in the control group. The most common organism detected in both the urethral and skin samples was coagulase-negative Staphylococcus aureus. Urethral colonisation was significantly greater in the control group compared to the chlorhexidine group, at 16/61 vs 0/50 (P = 0.001). Similarly, skin colonisation was significantly greater in the control group compared to the chlorhexidine group, at 10/61 vs 0/50, (P = 0.002). Conclusion: Chlorhexidine gel is a powerful sterilising agent that will render the urethra sterile.

Options for Masculinizing Genital Gender Affirming Surgery: A Critical Review of the Literature and Perspectives for Future Directions

INTRODUCTION

Masculinizing genital gender affirmation surgery (MgGAS) has witnessed significant change in recent years. With the increasing number of patients seeking out GAS, optimization of techniques is mandated.

OBJECTIVES

To critically review the evolution of MgGAS, in a manner that encompasses the history and scope of the procedures, including phalloplasty with and without urethral lengthening, metoidioplasty with and without urethral lengthening, penile prosthesis placement, scrotoplasty, testicular prosthesis placement, vaginectomy, and hysterectomy.

METHODS

A comprehensive literature review was conducted in accordance with PRISMA guidelines, using PubMed. For our search, we generated a comprehensive list of MgGAS, combined with synonyms for GAS to ensure that articles included transgender cohorts. We identified a total of 547 articles from the search terms. Of these articles, 144 abstracts were relevant. Among these abstracts, 108 manuscripts were reviewed in full of which 98 were acceptable for inclusion. We excluded non-English-language studies without translation and studies that did not describe primary gGAS (eg, revision surgeries).

RESULTS

The evolution of MgGAS encompasses mostly refinements of pre-existing procedures, rather than new techniques or "watershed" procedures. The literature is somewhat lacking in outcomes-reporting that identifies the specific anatomy and surgical technique(s) used during gGAS. Without clarity regarding anatomy and technique, it is not feasible to compare surgical outcomes.

CONCLUSION

There is no ideal MgGAS; thus, it is critical that the physician assist the patient in understanding the outcomes and potential morbidity of the procedures to make the most informed decision. We envision that the future of MgGAS will advance with refinement of surgical techniques that minimize complications, improvement of tissue therapeutic technologies, new surgical tools and prosthetics designed for gGAS, advances in aftercare, and an immense selection of surgical options.

A 10-year Audit of Penile Prosthesis Insertion

Introduction Penile prosthesis (PP) insertion is the gold standard surgical treatment option for men with refractory Erectile Dysfunction (ED). PP insertion is considered effective but has a well-documented array of complications. Our aim was to assess outcomes following single-surgeon insertion of PP for ED within an Irish cohort. Methods Following review of the Hospital In-Patient Enquiry (HIPE) system, a retrospective chart review of all patients who underwent PP insertion over a 10-year period from 2008-2017 inclusive was performed, and an electronic database was analysed for results. Results One-hundred-and-eleven PPs were inserted in 96 patients. The most common aetiology for ED in our cohort was post-prostatectomy, affecting 25 (26%) patients. The most frequently implanted device was a 3-piece inflatable PP (3p-IPP) (AMS 700TM; American Medical Systems Inc., Minnesota, USA) and the peno-scrotal approach was utilised in the majority of patients (86, 77.5%). No intraoperative complications were recorded. Twelve (12.5%) patients developed peri-operative complications. Thirteen (13.5%) patients required device revision, the majority for device failure. Of the 71 patient satisfaction responses, 61 (85.9%) patients were satisfied with their PP. Conclusions This single-surgeon retrospective audit of PP surgery demonstrates complication rates in-line with internationally published data. Patients should be adequately counselled regarding possible complications, including device failure and erosion. PP insertion should be considered for suitable patients with refractory ED.

Penile prosthesis implantation: A single center 25 years of experience

OBJECTIVES

We analyzed the long-term results of malleable and inflatable penile prosthesis: the rates of complications, revision surgery and patient satisfaction.

MATERIALS AND METHODS

Between January 1996 and December 2020, a total of 138 patients underwent implantation of a malleable or inflatable types penile prosthesis. The data of the patients were derived from the patient files and digital recording system. The patients were contacted face-to-face interaction if possible. If it is not possible, phone connection was made.

RESULTS

The median age of patients was 56 (21-83) years. Fourteen (10.2%) 1-piece, 46 (33.3%) 2-piece and 78 (56.5%) 3-piece penile prosthesis were implanted. The mostly used perioperative antibiotic was teicoplanin+amikacin in 107 patients. Total complication rate was 30% (n=42). Prosthesis infection constituted 9% (n=13) of these complications. The total satisfaction rate was 89.1%. There was no correlation between the complications and antibiotic regimen or prosthesis type (P=0.488, P=0.454, respectively). The rate of infection showed a slight increase in 3-piece penile prosthesis without any statistically significance (P=0.633). The patients with complications expressed more dissatisfaction compared to those without complications (P=0.001).

CONCLUSIONS

In our series, penile prosthesis implantation seems to be a recommended treatment method with high patient satisfaction in the treatment of refractory erectile dysfunction.

[The "right" patient for implant surgery in urology : Why patient selection, informed consent, and communication are so important for patient satisfaction]

In implant surgery for erectile dysfunction and urinary incontinence, adequate patient selection is essential for postoperative therapy success. Several scientific studies report patient satisfaction rates for penile implants and artificial urinary sphincter implantation of over 90%. Nevertheless, studies also report, that between 5 and 30% of the patients are not satisfied with the result of their operation. Sufficient patient information and consent prior surgical procedure in urological prosthetics are a key determinant for later patient satisfaction and therapy success. Diligent assessment of realistic expectations, possible complications, and risks must be made. Unrealistic and exaggerated expectations need to be met and discussed with the patient. Therefore adequate physician-patient communication is essential. Especially in the case of surgical revision or for patients with risk factors, the probability of complications is higher and may significantly increase later dissatisfaction. Also, the involvement of the partner plays a major role in later patient satisfaction in urological implant surgery. Finally, there is a group of patients for which the risk of later dissatisfaction is particularly high. These are patients with compulsive/obsessive behavior, unrealistic expectations, patients after revision surgery, self-entitled patients, as well as those patients who deny the extent of their illness, visit multiple surgeons (surgeon hopping) or have psychiatric illnesses. These patients are referred to with the acronym "CURSED" patients.

A comprehensive narrative review of residual curvature correction during penile prosthesis implantation in patients with severe erectile dysfunction and concomitant Peyronie's disease

Residual curvature correction during penile prosthesis implantation (PPI) is usually needed in patients with severe erectile dysfunction (ED) and concomitant Peyronie’s disease (PD). The aim of the study was to assess the different existing techniques for treating residual penile curvature during PPI in patients with severe PD and ED. We generated a comprehensive narrative review of the literature until August 2020 on the use of PPI in combination with straightening reconstruction techniques, in treating patients with severe PD and ED. We included studies published in English, assessing the PPI as primary intervention in patients with PD and ED. Secondary research studies and studies with insufficient data were excluded from final analyses. We included a total of 33 clinical articles with 1,612 patients that assessed the effects of PPI combined with straightening surgical techniques for the treatment of severe PD and ED. Based on the severity of penile curvature, the concomitance of additional penile deformities (i.e., hourglass deformity), the penile length, the presence of previous penile operations and the surgeon’s experience, four main categories of surgical techniques were identified: (I) PPI with plication of the penis on the convex side of the curvature, (II) transcorporeal plaque incision/excision, (III) PPI with plaque/tunical incision(s) on the concave side of the curvature and (IV) PPI with plaque incision/excision plus grafting. Patients with severe PD and ED can expect excellent outcomes with PPI and surgical correction of residual penile curvature and minimal side effects. Overall, all the above techniques seem to able to correct the residual penile curvature during prosthesis implantation. Grafting techniques seem to be favorable in patients with additional severe penile shortening. Still, no definite conclusions can be drawn regarding the superiority of one technique over the other.

A salvage procedure for redo penile prosthesis implantation in phalloplasty (De castro technique) for congenital aphallia

INTRODUCTION

We present a different salvage procedure for penile prosthesis implantation in a De Castro neophallus.

METHODS

A patient with congenital aphallia had been operated at the age of 11. Ten years later he had two non successful attempts of prosthesis implantation. Surgery consisted of adapting the implants into the aortic graft and folding it in the middle over the cylinders to reinforce its strength.

RESULTS

Patient had a successful postoperative course and has now 6 months of follow-up.

DISCUSSION

In a systematic review of penile prosthetic outcomes and complications in gender-affirming surgery, most of the prostheses were inflatable (83.6%) and single-cylinder (61.0%). At a mean follow-up of 3.0 years: 36.2% of prosthesis complications, 60.0% of patients had their original implant present and 83.9% reported achieving penetration. We decided to use vascular grafts as a scaffold because of former non successful attempts.

CONCLUSION

The use of vascular prosthesis as a device to implant the penile prosthesis seems to be a safe and effective alternative in an attempt to offer erectile function to the neophallus in case of congenital aphallia.

Global Trends in Prevalence, Treatments, and Costs of Penile Prosthesis for Erectile Dysfunction in Men

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.

[French Urological Association (AFU) guidelines for Peyronie's disease assessment and treatment]

INTRODUCTION

Peyronie's disease is a common cause for consultation in urology. Many controversies surround its treatment. No French Guidelines have been published so far. The Committee of Andrology and Sexual Medicine of the French Association of Urology therefore offers a series of evidence-based recommendations.

MATERIALS AND METHODS

These recommendations are made according to the ADAPTE method, based on European (EAU, ESSM), American (AUA, ISSM) and Canadian (CAU) recommendations, integrating French specificities due to the availability of treatments, and an update of the recent bibliography.

RESULTS

The assessment of the disease is clinical. Patients with functional impairment or significant psychological repercussions may be offered treatment. The benefits and drawbacks of each treatment should be explained to the patient. Regarding non-surgical treatments, no available treatment has market authorization in France. Vitamin E is not recommended. Analgesic (oral or low-intensity shock waves) or proerectile treatments may be offered as needed, as well as traction therapy. Due to the unavailability of collagenase injections, verapamil injections may be offered. Surgical treatments are to be considered in the stabilized phase of the disease, and consist of performing a plication, an incision-graft or the placement of a penile implant according to the patient's wishes, the curvature and the penis size, as well as erectile function. Combination treatments can be offered.

CONCLUSION

The management of Peyronie's disease is complex, and the levels of evidence for treatments are generally low. The success of treatment will depend on the quality of the initial assessment, the patient's information and understanding of the expected effects, and the practitioner's experience.

[Prosthetics after construction of the outer genitalia for transmen]

BACKGROUND

Growing awareness of gender identity issues and a rising prevalence of female-to-male transsexualism is increasing demand for surgical solutions that deliver both aesthetically and functionally satisfying outer genitalia for transmen.

OBJECTIVE

This article summarizes the available prosthetic options, describes different surgical approaches and reviews the outcome of prosthetics for transmen with a focus on penile prosthesis in phalloplasty.

METHODS

Current international standards of care, reviews and original publications are critically reviewed and correlated with our own experience with more than 400 transmen at two interdisciplinary referral centres in Frankfurt, Germany and London, UK.

RESULTS

Despite of a wide range of different phalloplasty techniques and prosthetic types, the currently most used technique is implantation of a three-piece, inflatable penile prosthesis in a radial-free-flap phalloplasty. There is still an ongoing debate about the number of implanted penile prosthesis cylinders, the use of customised corporoplasty-windsocks for the cylinder(s), and the location for the placement of the reservoir. At present there is only one penile prosthesis design for use in phalloplasties and long-term results are still pending.

CONCLUSION

There is still no ideal implant available for the use in phalloplasties. The current literature does not provide evidence-based treatment algorithms, which is also due to a lack of prospective randomised studies and validated measurement tools for the postoperative outcome. Initial data for the first transmen-specific penile prosthesis as well as an increase of transgender studies might lead to an improvement of treatment and the quality-of-life of the affected transmen.

A systematic review of penile prosthesis infection and meta-analysis of diabetes mellitus role

Background

Infection is the most feared complication of a penile prosthesis. Diabetes mellitus (DM) is widely known to increase the risk of several infections, but its role in the penile prosthesis is still controversial. This systematic review aims to show the contemporary scenario of penile prosthesis infection and present a meta-analysis about DM contribution to penile prosthesis infection.

Methods

The review was performed with no language or time limitation, including ten databases. The included articles were about the male population who received a penile prosthesis with no model restriction, with a minimum follow up of 1 year, and outcomes adequately reported.

Results

The mean infection incidence of penile prosthesis ranged from 0.33 to 11.4%. In early 2000, the general incidence of infection was 3 to 5%, then, the introduction of coated materials decreased it to 0.3 to 2.7%. The meta-analysis showed that diabetes mellitus is related to an increased risk of penile prosthesis infection with an odds ratio of 1.53 (95% CI 1.15–2.04).

Conclusions

Penile prosthesis infection decreased in the last decades but remains a significant cause of reoperation, and it is related to lower prosthesis survival. Meta-analysis concludes that diabetes mellitus is related to a higher risk of penile prosthesis infection.

Long-term outcomes after penile prosthesis placement for the Management of Erectile Dysfunction: a single-Centre experience

Background

Penile prothesis (PP) is the gold-standard treatment of drug-refractory erectile dysfunction (ED). While postoperative outcomes have been widely described in the literature, there are few data about patient satisfaction and intraoperative events. We aimed to assess long-term patient satisfaction and perioperative outcomes after PP implantation in a single-centre cohort of unselected patients using validated scales.

Results

A total of 130 patients received a PP (median age: 62.5 years [IQR: 58–69]; median International Index of Erectile Function (IEEF-5) score: 6 [IQR: 5–7]). Median follow-up was 6.3 years [IQR: 4–9.4]. Thirty-two (24.6%) patients underwent surgical revision, of which 20 were PP removals (15.4%). Global PP survival rate was 84.6% and previous PP placement was a risk factor for PP removal (p = 0.02). There were six (4.6%) non-life-threatening intraoperative events including two which resulted in non-placement of a PP (1.5%). EAUiaic grade was 0 for 124 procedures (95.4%), 1 for four procedures (3.1%) and 2 for two procedures (1.5%). Of patients who still had their PP at the end of the study, 91 (80.5%) expressed satisfaction.

Conclusions

PP implantation is a last-resort treatment for ED with a satisfactory outcome. PPs are well accepted by patients.

A Review on Penile Length and Girth Issues in Penile Prosthetic Surgery

PURPOSE OF REVIEW

The goal of this paper is to understand the reasons behind penile length and girth issues after penile prosthesis surgery and review the literature for current strategies employed to decrease these issues.

RECENT FINDINGS

Measurement inconsistencies triggering further studies have shown there is a real loss of penile length and girth after prosthesis surgery. There have been varying hypotheses of why this happens, and numerous approaches have been proposed to help combat this in the preoperative, intraoperative, and postoperative settings. Erectile dysfunction prevalence is expected to increase; therefore it is important for urologists to understand the treatment options, including prosthesis surgery. Numerous techniques have been hypothesized and studied in smaller settings in the preoperative, intraoperative, and postoperative settings with regard to prosthetics surgery. However, larger studies are still needed to confirm these findings in order to help to counsel and educate patients preoperatively in addition to employing tactics to help minimize penile shortening.

[Penile prosthesis for erectile dysfunction in the neurological patient, indication, complications and satisfaction: Retrospective study on 27 patients]

INTRODUCTION

Penile prosthesis for erectile dysfunction in patients with spinal cord injury or multiple sclerosis is sometimes discussed after failure of drug or instrumental treatments (vacuum). The objective of this study was to evaluate the complications, evolution and patient satisfaction after the implantation of a penile prosthesis in the neurological patient.

MATERIALS AND METHODS

Multi-center retrospective study of 27 consecutive patients including 18 spinal cord injured patients and 9 patients with multiple sclerosis benefiting from the implantation of a penile prosthesis for erectile dysfunction purposes in two French centers between 2009 and 2019. Post-implantation complications, evolution of the use of the prosthesis and global patient satisfaction were evaluated using the standardized questionnaire Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) during a telephone call between March and May 2020.

RESULTS

The average age of implantation was 46.4 years (±12.74). The length of follow-up to date of call was 6.05 years (±2.86). 8/27 patients (29.6 %) had at least one complication of any Clavien-Dindo grade included 2 infection. 2/27 (7,4 %) patients had a mechanical prosthesis injury during follow-up. The patient's dexterity with inflation of the prosthesis was perfect in 85 % of cases, and 75 % for deflation. The satisfaction rate for prosthesis use at the time of the call was 75.36/100pts for the patient and 66.88/100pts for the partner.

CONCLUSION

This study found an increased rate of prothesis infection compared to the general population in the neurologic patient, but patient and partner satisfaction remain sustainable after more than 5 years of implantation. Dexterity was maintained over the long term, demonstrating a good selection of indications. These data invite to favorably consider the installation of a penile prosthesis in neurological patients who have failed first-line treatments.

[Health care reality of urological endoprosthetics in Germany from 2006 to 2016]

Hintergrund

Die Behandlung von Harninkontinenz und erektiler Dysfunktion verbessert die Lebensqualität vieler Patienten. Insbesondere die Endoprothetik mit Sphinkter- und Penisprothesen erzielt hierbei sehr gute Ergebnisse, wenn konservative Therapieoptionen ausgeschöpft sind. Ziel dieser Studie ist eine Darstellung der Entwicklung und aktuellen Versorgungslage der Sphinkter- und Penisprothesenimplantation in Deutschland.

Material und Methoden

Wir führten eine Analyse der Diagnosis-Related-Groups-Abrechnungsdaten in Deutschland im Zeitraum von 2006 bis 2016 durch. Die Versorgungslage im Jahr 2016 beschrieben wir auf Basis der Qualitätsberichtsdaten der deutschen Krankenhäuser.

Ergebnisse

Von 2006 bis 2012 stieg die Zahl der implantierten Sphinkterprothesen in Deutschland von 739 auf 1112 (p < 0,001) und die Zahl der implantierenden Kliniken von 129 auf 206 (p < 0,001). Von 2012 bis 2016 fielen die Fallzahlen auf 980 und die Zahl der Kliniken auf 198. Im Jahr 2016 implantierten 168 (88 %) urologische Kliniken 1–9 Sphinkterprothesen und 23 (12 %) Kliniken ≥ 10 Sphinkterprothesen. Die 10 Top-Kliniken (≥20 Sphinkter) implantierten 34 % (283/839) aller Sphinkter. Von 2006 bis 2013 stieg die Zahl der implantierten Penisprothesen kontinuierlich von 263 auf 503 (p < 0,001) sowie die Zahl der implantierenden Kliniken von 71 auf 107 (p < 0,001). Von 2013 bis 2016 stagnierte die Fallzahl (p = 0,9) und die Zahl der implantierenden Kliniken (p = 0,5). Der Anteil implantierter Penisprothesen im Rahmen von Geschlechtsumwandlungen stieg von 17 % im Jahr 2006 auf 25 % im Jahr 2016 (p = 0,03). Im Jahr 2016 implantierten 83 (85 %) urologische Kliniken 1–6 Penisprothesen und 14 (15 %) Kliniken ≥ 7 Prothesen. Die 7 Top-Kliniken (≥20 Prothesen/Jahr) implantierten 232/448 (52 %) der Prothesen.

Diskussion

Der Versorgungsstand der urologischen Endoprothetik in Deutschland zeigt eine deutliche Zentrenbildung, aber auch eine große Zahl von Kliniken mit geringer Fallzahl. Seit 2012/2013 zeigt sich eine Stagnation der Fallzahlen von Penis- und Sphinkterprothesenimplantationen, die in Zusammenschau mit den Prostatektomiefallzahlen eine Unterversorgung vermuten lässt.

Current Status for Semirigid Penile Prosthetic Devices

PURPOSE OF REVIEW

The goal of this paper was to evaluate the current use of semirigid penile prosthesis (SRPP), surgical techniques for insertion of SRPP, and how to prevent and approach surgical complications.

RECENT FINDINGS

SRPP is a valid option for those who are refractory to medical therapy for erectile dysfunction (ED) and even more appropriate for specific subsets of patient populations. It is important for urologists to know which patient population SRPP is preferred for. Several studies have shown good patient outcomes and patient satisfaction with those who underwent SRPP.

"Pumpology": the Realistic Issues Associated with Pump Placement in Prosthetic Surgery

PURPOSE OF REVIEW

The goal of this paper was to discuss the issues and/or overt complications associated with the 3-piece inflatable penile prosthesis (3-IPP) pump. We also addressed how to resolve such issues with or without surgical intervention.

RECENT FINDINGS

Numerous modifications of the 3-IPP pump have been introduced with multiple techniques to place the pump. These are largely dependent on the approach to place the 3-IPP. Pump issues may inevitably occur, and there are numerous special maneuvers that can be performed to resolve pump issues. It is important for urologists to know maneuvers for pump malfunctions to prevent unnecessary surgical procedures and pump revision. Several studies are reviewed regarding pump issues and patient satisfaction; however, a more structured prospective research project is warranted to further evaluate these issues.

Can malleable penile prosthesis implantation improve voiding dysfunction in men with concurrent erectile dysfunction and buried penis?

Purpose

A buried penis causes voiding dysfunction and limits penetrative sexual intercourse. This pilot study evaluates the urinary outcomes in men with buried penis following insertion of malleable penile implants.

Materials and Methods

Men with buried penis and co-existing urinary problems and erectile dysfunction underwent malleable penile prosthesis implantation were reviewed in a prospective ethics approved database. Patient demographics, flow rate (Qmax), International Prostate Symptom Score (IPSS), Patient Global Impression of Improvement (PGI-I) score, International Index of Erectile Function (IIEF)-5 score, Sexual Encounter Profile (SEP) and overall satisfaction score (on a 5-point scale) were recorded.

Results

A total of 12 men (age 55 to 72 years) were reviewed, and the average gain in penile length post-implant, as measured from the pubis to the tip of the glans penis, was 6.8 (3 to 8) cm. There was a significant improvement in IIEF-5 score (8.2 vs. 22.5; p=0.029) post-implant, and more than half of patients were able to resume normal sexual intercourse and positive SEP-2 and SEP-4 were reported in 9 (75%) and 8 (67%) patients. There were no significant intraoperative or postoperative complication. Significant improvement in Qmax (8.4 ml/s vs. 18.6 ml/s; p=0.042) and IPSS (24.5±5.5 vs 15.5±3.5; p=0.038) were observed. More than two-thirds (83%) reported PGI-I score at 1 or 2, while 9 (75%) patients scored a 5/5 in overall satisfaction rate.

Conclusions

Malleable penile implants increases penile length and improves urinary function in a highly select group of men with a buried penis and erectile dysfunction.

[Quality of life in patients who suffered erectile dysfunction and underwent penile implant surgery in terms of sexual satisfaction of the patient and partner]

BACKGROUND

Erectile dysfunction is a condition that shows a continuously growing prevalence in the male population. The penis prosthesis implant (PPI) qualifies as an effective form of therapy.

OBJECTIVES

The aim of this study was to analyze the sexual satisfaction rate and quality of life in patients who had suffered from erectile dysfunction and who were treated with a penile prosthesis. The patient's partners were also surveyed.

METHODS

We collected data from patients who underwent surgery in the Center of Excellence for Penile Implants, University Hospital Schleswig-Holstein, Campus Kiel, Kiel, Germany. Questionnaires with validated scores (EDITS, EDITS Partner) were sent to all patients and their partners via mail.

RESULTS

The satisfaction rate in this study was high which shows that the patients and partners are pleased, and the high sexual satisfaction rate led to a higher quality of life.

CONCLUSION

The penile prosthesis implantation as a last option of therapy for erectile dysfunction is useful and brings more than adequate results.

Infected penile prosthesis: literature review highlighting the status quo of prevention and management

INTRODUCTION

Erectile dysfunction affects over 50% of men 70 years and above, and penile prosthesis (PP) is its third-line treatment. Complications of PPs include infection, however, no formal guidelines exist for its management.

METHODS

We performed a literature search and reviewed 53 recent published literatures of experiences with management of PP infections, prevention, and treatment.

RESULTS

Acute infection can present early with pain and discharge and detection of early signs is of utmost importance. MRI studies are more sensitive than CT studies to diagnose and plan surgical intervention. Introduction of antibiotic impregnated devices attributed to the reduction of infection rates with superiority proven for certain types; the no-touch technique had further reduced this rate. The Mulcahy salvage remains the most widely used surgical approach for treatment despite modifications and novel techniques described; conservative management of PP infections is recently reported with promising results.

CONCLUSIONS

Despite absence of strict guidelines for the management of infected PPs, we reviewed and discussed numerous panel opinions and suggestions throughout literature. More research into the pathology, prevention, conservative management and advances in surgical treatment of this condition are called for to produce guidelines that unite the efforts to tackle these infections.

Management of proximal penile prosthetic cylindrical complications: a novel direct crural approach

Introduction

Patients with proximal penile prosthetic cylindrical complications (PPPCC) can be treated with a direct crural technique without using the original traditional approach. In this article we present our novel direct crural approach for management of patients with PPPCC.

Materials and methods

Between 2014 and 2019, data were retrospectively collected from 13 patients who underwent surgical revision using our novel direct crural approach for PPPCC. The procedure commences with identification of the affected zone. The patient is in a low lithotomy position. A 2-centimeter longitudinal incision is made directly over the affected site. Dissection is carried down through Colles’ fascia, followed by a longitudinal incision through the tunica albuginea at the proximal part of the affected cylinder. Via the incision we can deliver out the cylinder and manage its problem.

Results

Mean operative time was 40 min. No intra or post-operative complications were reported. All patients (Mean age = 57) were discharged on the same day. Postoperative follow-up found correction of all existing deformities at month 1, 3 and 6. All patients were satisfied and reported less pain and faster recovery than the first procedure.

Conclusion

Our technique, which can be used for all types of penile prosthesis, is both feasible and safe. It may simplify PPPCC revision by avoiding adhesions below the original incision, without jeopardizing the already implanted materials or the urethra. It may also improve patients’ safety and satisfaction, by reducing iatrogenic injury and post-operative recovery time.

[Gender reassignment from female to male : Phalloplasty]

BACKGROUND

The increasing prevalence of gender dysphoria necessitates an evaluation of the literature of phalloplasty techniques for female to male transgender individuals.

OBJECTIVE

The following article provides an overview of the current surgical concepts and complications of phalloplasty, associated urethrogenitoplasty and the implantation of prostheses in phalloplasty.

MATERIAL AND METHODS

Current international reviews and original publications from 2010 to 2020 were reviewed and correlated with our referral center experience with more than 350 female to male transgender patients over the last 25 years.

RESULTS

Free radial forearm flap phalloplasty is the most widely used technique, followed by an anterolateral thigh flap (ALT flap) and pedicled or microsurgical transplantation. Hydraulic multicomponent prostheses are given preference and supplementary surgical techniques, such as scrotoplasty and glans sculpturing can make sense or be necessary. The complication rates after phalloplasty and after insertion of penile prostheses are substantial. Nevertheless, the overall patient reported satisfaction rate in the majority of studies is often over 80%.

CONCLUSION

Due to the increasing prevalence of gender dysphoria there is currently a need for interdisciplinary referral centers for gender reassignment surgery. A certain standardization of surgical techniques and timing would be desirable but a review of the current literature shows a high heterogeneity so that this cannot be derived from the currently available literature. It is hoped that the recently founded S2K guideline committee on operative treatment of gender dysphoria under the auspices of the German Society for Urology and the Society for Plastic and Reconstructive Surgery can report an initial collection of experiences in 2021.

MRI of common penile pathologies and penile prostheses

MRI can delineate finer details of penile anatomy and pathology due to inherent higher soft-tissue contrast and spatial resolution. It can characterize inflammation and identify abscesses, localize penile fractures, guide surgical planning in penile fibrosis and Peyronie's disease, and depict components of the penile prosthesis and its complications. MRI is a great investigative tool for penile neoplasms, including locally infiltrative neoplasms where clinical examination is limited, and local staging is crucial for surgical planning.

Promising role of medicinal plants in the regulation and management of male erectile dysfunction

Male erectile dysfunction (ED) refers to incompetency to reaching and retaining adequate penile tumescence for sexual intercourse. Over 152 million men globally suffer from ED and by 2025, the number of affected individuals is anticipated to be around 322 million. Pharmacological and nonpharmacological therapies such as phosphodiesterase (PDE) inhibitors, alprostadil, penile prosthesis surgery, and hormonal replacement are available for management and recuperation of ED. Nevertheless, such therapies are reported to have adverse effects as well as life-threatening. Accordingly, diversity of medicinal plant species and bioactive active compounds are preferred as therapeutic options because they are natural, abundant, available, low-cost and cause fewer or no side effects. This current review will emphasise the aetiology, risk factors, mechanisms underlying the pathophysiology of ED, treatments of ED as well as their side effects. It also provides medicinal plants that are proven effective in vivo and in vitro for the mitigation and treatment of male ED. This knowledge could be used in the future in drug discovery for the development of more natural drugs with no side effects.

Superficial glans ischemia after penile prosthesis successfully treated by conservative treatment

Glandular ischemia is an extremely uncommon dreaded postoperative complication of inflatable penile prosthesis surgery that may lead to penile gangrene and organ loss, whose incidence is difficult to determine. We report the case of a 56-year-old male admitted to our department with complaints of cold and painful glans penis after penile implant one month before. A color Doppler examination revealed the normal intracavernosal arteries with no vascularity in the superficial glans tissues. Due to the mild severity of the ischemia, conservative management was suggested, and consisted of oral pentoxifylline and hyperbaric therapy for 10 days, achieving a significant improvement at 4 months of follow-up.

Do candidates for penile implant prefer their doctors or another implanted patient as their information source? Results of a pilot study

INTRODUCTION

Erectile dysfunction incidence is about 19-26 cases for every 1000 men/year, requiring about 20,000 penile implants/year. There is high demand for information on the part of patients, however, there is a lack of evidence about the sources of information prior to penile implant and the figure of the Expert Patient (EP) has never been described in this area.

AIMS

To evaluate the sources of information used by candidates for penile implant as well as to describe the role of the EP as an information source.

METHODS

Pilot study of candidates for penile prosthesis. Patients already implanted attending for exchange or reallocation surgery were excluded. Each patient had an interview with an EP, and commercial documentation was given. Each source of information was evaluated in a face-to-face interview. SPSS™ version 20.0 was used.

MAIN OUTCOME MEASURES

The EP was evaluated by the International Index of Erectile Function, the Generalized Anxiety Disorder 7 questionnaire, and the Erectile Dysfunction Inventory of Treatment Satisfaction. Each source of information was evaluated by a non-validated 6-section questionnaire.

RESULTS

Ten patients were included. Mean age was 60±10.3 years. Medical interview with the urologist resulted in a global value and truthfulness score of 9.2±.9 and 9.8±.4, respectively. Commercial information had a global score of 8.5±.9 and a truthfulness score of 8.6±.6, while the internet had 6.8±.8 points for global value and 7.2±1 for truthfulness. The global score of the EP was 8.7±1.2 points and their veracity scored 9.6±.5 points.

CONCLUSIONS

The urologist remains the main source of information for patients with erectile dysfunction candidates for penile prosthesis implant. However, the EP is an alternative and could be a key pillar in presurgical counselling.

The Use of Antiseptic Solutions in the Prevention and Management of Penile Prosthesis Infections: A Review of the Cytotoxic and Microbiological Effects of Common Irrigation Solutions

INTRODUCTION

The Mulcahy salvage fundamentally altered the management of penile prosthesis infections (PPI). Central to this procedure is a sequence of antiseptic irrigations that aims to remove and eradicate pathogenic microflora from the infected field, thus preparing for immediate reimplantation. The antiseptic solutions and their respective concentrations, however, have never been evaluated for efficacy.

AIM

This review critically examines 3 commonly used antiseptic irrigation solutions (povidone-iodine [PVI], hydrogen peroxide [H₂O₂], and chlorhexidine gluconate [CHG]) in terms of their antimicrobial activity, cytotoxicity, and clinical use.

METHODS

A PubMed literature review was performed on articles published between 2003 and 2018. Both preclinical as well as clinical studies from various surgical disciplines were included in this review.

MAIN OUTCOME MEASURE

The original salvage protocol selected for irrigation solutions at concentrations that are likely detrimental to native tissue.

RESULTS

All 3 agents demonstrate in vitro cytotoxic effects at subclinical concentrations, but H₂O₂ is associated with the most significant deleterious properties. It does not seem to broaden antimicrobial coverage beyond what is covered by PVI. Dilute PVI (0.35-3.5% with exposure time of at least 3 minutes) possesses the most robust clinical evidence as an intraoperative adjunct, reducing the incidence of postoperative infectious complications. chlorhexidine gluconate is a promising new agent but lacks clinical data.

CLINICAL IMPLICATION

Improvements in the salvage protocol are warranted based on current evidence. Careful selection of lavage solution and usage of the lowest necessary concentration will help achieve desired antimicrobial activity while avoiding native tissue cytotoxicity. Strength and limitation: The study is limited by its retrospective nature, and the heterogeneity of literature reviewed precluded a formal meta-analysis. Furthermore, future studies will need to address the roles of normal saline and antibiotic irrigations as intraoperative adjuncts for infection prevention.

CONCLUSION

Diluted PVI (0.35-3.5% for 3 minutes) may be beneficial in the prevention of PPI. Evidence supports its use both in the setting of primary implantation as well as salvage of infected hardware. An improved, evidence-based protocol may increase positive outcomes of urologic prosthetic surgery. Pan S, Rodriguez D, Thirumavalavan N, et al.

Enlargement of length and girth associated with implantation of penile prostheses

INTRODUCTION

Reduction in penile size is due to numerous conditions including Peyronie's disease, previous penile surgeries, diabetes, trauma, erectile dysfunction, pelvic surgery, and aging. Elasticity of the tunica albuginea is adversely affected by any of the above. Fibrosis then triggers progressive erectile dysfunction OBJECTIVES: When a penile prosthesis is indicated, it is important to determine whether the penis has already diminished in size prior to insertion of the implant. Because a prosthesis only provides axial rigidity and is not associated with the enlargement of the penis, reflection of strategies to simultaneously enlarge the size of the penis while implanting a device is recommended.

MATERIAL AND METHODS

A systematic review of current scientific literature regarding procedures and tactics currently available for penile implants and enlargement was conducted.

RESULTS

The literature demonstrates that the evolution of penile implant surgery, accompanied by consideration of enlargement, has evolved through 5 fundamental techniques: Incision with Grafting; Sliding with Grafting; Modified Sliding without Grafting (MoST); Multiple Slit without Grafting (MUST); and the Egydio Paradigm for Tunica Expansion Procedures (TEP), a further evolution of previous strategies to achieve state of the art penile implantation accompanied by maximum penile enlargement. Evolving technology of tunica expansion procedures has led to diminution of the size of tunica defects and avoidance of grafts to prevent bulging and indentation, while developing solutions to preserve the strength of the tunica albuginea for firm positioning of the cylinders in the interior of the corpora cavernosa.

CONCLUSIONS

The evolution of these techniques is the transformation of larger tunica defects into smaller ones. While grafts are often used to reinforce the penile structure due to large defects, multiple incisions of the tunica albuginea are gaining popularity to promote girth and length enlargement without grafts and without the loss of tunica strength necessary to support the cylinders inside the corpora.

Clinical guidelines on erectile dysfunction surgery: EAU-AUA perspectives

INTRODUCTION

The implantation of a penile prosthesis is considered a third-line treatment and is indicated in patients who do not respond adequately to pharmacotherapy or require definitive treatment. Currently, the most used devices are 3-component penile prostheses, which presently account for more than 90% of the implants used.

MATERIAL AND METHODS

We reviewed the evidence and the recommendations of the clinical practice guidelines regarding surgery in patients with erectile dysfunction.

RESULTS

The recommendations of the clinical practice guidelines on surgery in patients with erectile dysfunction are summarized as follows: men with erectile dysfunction should be informed about the option of penile prosthesis implant treatment, commenting on the benefits, risks and consequences; men with erectile dysfunction who have agreed to receive penile prosthesis should be advised on post-surgical expectations; penile prosthesis implants should not be performed in patients with systemic, cutaneous or urinary tract infection; in young men with erectile dysfunction and focal penile or pelvic arterial obstruction who do not have generalized vascular disease or veno-occlusive dysfunction, penile arterial reconstruction can be considered; in men with erectile dysfunction, penile venous surgery is not recommended.

CONCLUSIONS

The use of penile prostheses offers high satisfaction rates to both the patient and his partner. However, it is crucial to adequately inform and warn patients about possible complications and consequences.

Organization of the operating room and specific instruments for the implant of penile prosthesis

After more than 1600 penile implant surgeries, we can affirm the need for a procedure protocol of the steps prior to this type of surgery, and the importance of carefully control the preparation for the surgical act. The instruments that must be available for surgery include elements that have been specifically designed for this type of intervention, such as the Cavernotomo dilators (Rossello®) or the Furlow. These are essential for penile implant surgeries in the usual practice, especially in complex cases or when complications arise. We should avoid complications as much as we can, or at least we should be able to minimize, address and resolve them with effective organization and adequate instruments. Undoubtedly, the surgeon's skills and experience are one of the key components for success, but the great importance of an adequately performed and rigorously applied protocol by all team members should not be underestimated. The objective of this article is to explain the basis of the details of this procedure in a clear and realistic way.

Intraoperative and postoperative complications of penile implant surgery. Diagnosis and treatment

We describe the most frequent complications associated with penile implant surgery, paying special attention to their practical management. We have analyzed preoperative complications and postoperative complications separately. The intraoperative include perforation of the corpora cavernosa during dilation, cylinder cross-over or cross-placement and urethral injury during implantation. The most frequent postoperative complications are mechanical failure, cylinder erosion and prosthesis infection. We emphasize on rescue surgery and reimplantation techniques in cavernous tissue fibrosis.

Analysis of satisfaction and surgical outcomes of a major ambulatory surgery program for penile implant

INTRODUCTION AND OBJECTIVE

Penile prosthesis (PP) surgery is performed in many institutions as an inpatient procedure. We have recently initiated a major ambulatory surgery (MAS) program, thus reducing the hospital stay. The objective of this study was to assess the feasibility, complications and satisfaction of the implantation of outpatient surgery PP program in our hospital.

MATERIAL AND METHODS

Retrospective observational study evaluating the results and satisfaction of PP implanted as an outpatient procedure in Bellvitge University Hospital during 2018.

RESULTS

During 2018 we implanted 49 PP: 27 (55%) inpatient surgeries vs. 22 (45%) outpatient surgeries. Of these 22, 2 (9%) were second implants. All patients underwent both general anesthesia and crural, proximal dorsal nerve and transversus abdominis plane block (TAP). Complication rates between inpatient and outpatient procedures were similar, 2 (7%) and 1 (5%), respectively, without reporting infections or requiring PP removal. Postoperatively, a satisfaction telephone survey was conducted in 19 (86%) patients: 16 (84%) considered the time of hospital stay as appropriate, 15 (79%) would have preferred to be operated again in an outpatient care setting and 15 (79%) would recommend it. The patients' main concerns were related to being at home with no medical assistance at home and about coming back the next day for drainage removal. All patients reported well-controlled pain without requiring opioid intake in any case.

CONCLUSIONS

In our series, PP implantation in an ambulatory care setting is feasible and safe. Although there are some aspects that should be improved, the program showed acceptable satisfaction rates and an adequate postoperative pain control, neither raising the administration of opioids, nor increasing complications and re-admission rates.

Infrapubic surgical approach for penile prosthesis surgery: Indications and technique

CONTEXT

Penile prosthesis surgery is currently the most effective treatment for erectile dysfunction when medical treatment is ineffective or contraindicated. Among the surgical approaches described in the literature, the scrotal, infrapubic and subcoronal are the most common in the daily clinical practice.

OBJECTIVES

The main objectives were to describe the infrapubic surgical technique evaluating its indications and complications, as well as comparing its advantages and disadvantages with the penoscrotal approach.

ACQUISITION AND SYNTHESIS OF THE EVIDENCE

A literature review from 1983 until current date was carried out in Medline (PubMed and Cochrane Library databases) following PRISMA standards. Sixteen studies were included: 4 prospective, 4 retrospective, one systematic review, one randomized trial, one original article, 5 expert opinion/surgical technique descriptive paper.

DISCUSSION

According to the literature reviewed, although the penoscrotal approach is the most applied, the infrapubic approach showed a shorter operative time and a tendency for an earlier recovery of sexual activity after surgery. Complications are rare, having similar rates to the penoscrotal approach; no cases of glans hypoesthesia have been reported and peri-prosthetic infection rates were less than 3%. Satisfaction rates of infrapubic penile prosthesis were higher than 80%.

CONCLUSIONS

Penile prosthesis implantation requires of a profound knowledge of the different surgical approaches in order to best adapt each technique based on each individualized case. The infrapubic approach, even if it is not the most used, is as feasible and reliable as the penoscrotal approach. The infrapubic approach is effective and safe, with high level of both, patients and partners' satisfaction.

Analysis of preoperative and postoperative expectations of penile implant candidates

Penile prosthesis implantation is a good option for the treatment of refractory erectile dysfunction. However, the patient's expectations, among other factors, condition his satisfaction after surgery. This review article aims to present the scientific evidence available concerning patient satisfaction with penile prosthesis surgery.
