Efficacy and safety of malleable penile prosthesis compared to inflatable penile prosthesis in erectile dysfunction patients.

INTRODUCTION: Erectile dysfunction can cause self-withdrawal and decreased quality of life. Patients who do not respond to pharmacological therapy and other conservative treatments are urged to undergo penile prosthesis implantation. Malleable penile prosthesis was the first prosthesis developed, but then inflatable penile prosthesis was developed to give a more natural erection. There is no meta-analysis comparing inflatable and malleable penile prostheses in terms of safety and efficacy. This study is conducted to evaluate patient and partner satisfaction, ease of use, mechanical failure, and infection rate in patients who underwent penile prosthesis implantation. METHOD: This meta-analysis followed Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) protocols. Five eligible studies were included from Pubmed, Scopus, ScienceDirect, and SemanticScholar databases. RESULT: In this study, patient and partner satisfaction are significantly better (OR 3.39, 95% CI 1.66-6.93, p = 0.0008) (OR 2.32, 95% CI 1.75-3.08, p < 0.00001). Mechanical failure is also significantly higher in inflatable penile prostheses (OR 5.60, 95% CI 2.02-15.53, p = 0.0009). There is no significant difference in terms of ease of use and infection rate in inflatable or malleable penile prostheses. CONCLUSIONS: This study concluded that inflatable penile prosthesis is better in terms of patient and partner satisfaction, but mechanical failures occur more frequently in this type of prosthesis.

A systematic review comparing different approaches for inflatable penile prosthesis revision: partial-component exchange, complete-component exchange, or reservoir "drain and retain".

INTRODUCTION: In cases of a noninfected malfunctioning inflatable penile prosthesis (IPP) device, surgeons often opt to exchange all of the device rather than the defective component for fear of an increased infection rate and future mechanical dysfunction. OBJECTIVES: To assess whether partial-component exchange of an IPP device has comparable outcomes to complete explant and replacement of an IPP device with or without a retained reservoir. METHODS: A systematic review was conducted following the PRISMA 2020 and AMSTAR guidelines. Searches were performed on MEDLINE (Ovid), PubMed, and the Cochrane Library from inception to June 2023, identifying studies reporting outcomes and complications of revision surgery for noninfected malfunctioning IPP devices. Three groups were compared: those undergoing single- or 2-component exchange, those with complete explantation and replacement, and those with replacement of all components while retaining the primary reservoir. RESULTS: Analysis included 11 articles comprising 12 202 patients with complete device replacement, 234 with partial device exchange, and 151 with retained reservoirs following revision. Mean ages ranged from 62 to 68 years, with median follow-up times between 3 and 84 months. Partial-component exchange showed a higher infection rate (6.3%) as compared with complete replacement (2.7%) and reservoir retention (3.9%). Similarly, partial exchange had a higher complication rate (23.9%) when compared with complete replacement (11.3%) and reservoir retention (19.6%). Mechanical failure rates for partial exchange were similar across the 3 groups (10%, 2.8%, and 5.8%, respectively). CONCLUSION: Partial-component exchange during IPP revision is associated with higher infection and perioperative complication rates but comparable rates of mechanical failure as compared with complete-component replacement, with or without retaining the original reservoir.

Use of Soft Penile Prosthesis in Grafting Surgery for Peyronie's Disease and Mild Erectile Dysfunction: Still an Option?

BACKGROUND: Plaque incision and grafting (PEG) is a primary surgical therapy for severe penile curvature in Peyronie's disease (PD); However, it can increase the risk of erectile dysfunction (ED), particularly in patients with pre-operative mild ED. Soft penile prosthesis (SPP) implantation is a viable treatment option in such cases. This study aims to compare the outcomes of PEG-only approach to PEG plus SPP implantation. METHODS: Between 2010 and 2019, 32 patients with PD and mild ED (5-item version of the International Index of Erectile Function scores: 17-21) underwent PEG surgery. Two groups were defined based on the surgery type: PEG-only and PEG plus SPP. The long-term outcomes included correction of penile bending, erection quality, intercourse ability, penile length and sensitivity. The overall satisfaction and impact of surgery on sexual activity and quality of life were also assessed. RESULTS: Of the 32 patients, 13 (40.6%) underwent PEG-only surgery, whereas 19 (59.4%) underwent PEG plus SPP. No significant differences were noted between the groups regarding pre-operative characteristics (all p > 0.1) or intra- and post-operative complication rates (all p > 0.2). The median patch area was larger in the PEG-only group (28 cm2 vs. 16.2 cm2; p = 0.001), whereas patients in the PEG plus SPP group were more likely to receive a single patch implant (100% vs. 53.8%; p < 0.001). The penile length increased in 18 patients (61.6%), with significant differences between the two groups (30% vs. 81.2%; p = 0.03). Overall, 14 patients (53.8%) reported greater satisfaction with their sexual life post-operatively, with comparable rates between the groups (p = 0.2). No significant differences were found in the post-operative 5-item version of the International Index of Erectile Function scores or severe post-operative ED (all p > 0.5). CONCLUSIONS: SPP placement during corporoplasty in patients with mild ED is safe and feasible, and it may be a suitable option for patients uncertain about inflatable prosthesis placement. The use of SPP resulted in longer penile lengths and necessitated smaller grafts. However, further data are required to understand the long-term clinical implications of this approach.

Salvage procedures for infected penile implants: A comprehensive review and analysis of functional outcomes.

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

50 years of inflatable penile implants: Where do we stand in France?

INTRODUCTION: With 50 years' experience, inflatable penile implants are the preferred option for erectile dysfunction refractory to pharmacological and mechanical treatment. Technical and surgical improvements have optimized patient success and satisfaction. However, multi-factorial dissatisfaction persists. OBJECTIVE: The aim of this study is to provide an overview of available technological improvements and innovations, as well as the perioperative management and complications of inflatable penile implant surgery. METHOD: A literature review was carried out over the last twenty years to answer 4 questions: what are the different inflatable penile implants available in 2023, for which indications, results and complications. RESULTS: Four companies propose inflatable penile implants in France. The main improvements have been in the various components of the prosthesis with better cylinder extension, more ergonomic reservoirs, and more manageable pumps, leading to a better durability. Indications have been extended to patients suffering from Peyronie's disease and in emergency cases of priapism. In response to demand from the transgender population, specific phalloplasty implants have been developed. New options are being developed for difficult cases of retracted penis. Results show a high satisfaction rate. Currently the main challenge is the management of infection with the development of rescue protocols using antibiotics to preserve implants - or replace them in a single operation. CONCLUSION: After 50years' experience, improvements in penile implants led to effective, satisfactory and safe treatment and can be proposed in new indications. Further development is sill necessary to offer solutions in difficult cases.

Surgical management of complex curvature in Peyronie's disease.

PURPOSE: About 10% of Peyronie's patients are complex cases with severe curvature (>60 degrees), ventral plaque, multiplanar curvature, hour-glass/hinge deformity, notching deformity, and ossified plaque. In patients with complex Peyronie's disease (PD), different techniques (shortening procedures, lengthening procedures, and penile prosthesis implantation (IPP)) may be necessary to achieve successful result. This review aims to analyze the various surgical techniques employed in the management of Peyronie's disease, with a specific focus on patients with complex deformity. METHODS: Articles focusing on the surgical management of complex curvature in Peyronie's disease were searched in MEDLINE and PubMed published between 1990 and 2023. RESULTS: Shortening procedures are linked to penile shortening and are not recommended for complex cases such as notching, hour-glass deformity, or ossified plaque. Lengthening procedures are suitable for addressing complex curvatures without erectile dysfunction (ED) and are a more appropriate method for multiplanar curvatures. Penile prosthesis implantation (IPP), with or without additional procedures, is the gold standard for patients with ED and Peyronie's disease. IPP should also be the preferred option for cases of penile instability (hinge deformity) and has shown high satisfaction rates in all complex cases. CONCLUSION: While surgical interventions for complex curvature in Peyronie's disease carry inherent risks, careful patient selection, meticulous surgical techniques, and post-operative care can help minimize complications and maximize positive outcome.

Development and validation of 3-dimensional simulators for penile prosthesis surgery.

BACKGROUND: The acquisition of skills in penile prosthesis surgery has many limitations mainly due to the absence of simulators and models for training. Three-dimensional (3D) printed models can be utilized for surgical simulations, as they provide an opportunity to practice before entering the operating room and provide better understanding of the surgical approach. AIM: This study aimed to evaluate and validate a 3D model of human male genitalia for penile prosthesis surgery. METHODS: This study included 3 evaluation and validation stages. The first stage involved verification of the 3D prototype model for anatomic landmarks compared with a cadaveric pelvis. The second stage involved validation of the improved model for anatomic accuracy and teaching purposes with the Rochester evaluation score. The third stage comprised validation of the suitability of the 3D prototype model as a surgical simulator and for skill acquisition. The third stage was performed at 3 centers using a modified version of a pre-existing, validated questionnaire and correlated with the Rochester evaluation score. OUTCOME: We sought to determine the suitability of 3D model for training in penile prosthesis surgery in comparison with the available cadaveric model. RESULTS: The evaluation revealed a high Pearson correlation coefficient (0.86) between questions of the Rochester evaluation score and modified validated questionnaire. The 3D model scored 4.33 ± 0.57 (on a Likert scale from 1 to 5) regarding replication of the relevant human anatomy for the penile prosthesis surgery procedure. The 3D model scored 4.33 ± 0.57 (on a Likert scale from 1 to 5) regarding its ability to improve technical skills, teach and practice the procedure, and assess a surgeon's ability. Furthermore, the experts stated that compared with the cadaver, the 3D model presented greater ethical suitability, reduced costs, and easier accessibility. CLINICAL IMPLICATIONS: A validated 3D model is a suitable alternative for penile prosthesis surgery training. STRENGTHS AND LIMITATIONS: This is the first validated 3D hydrogel model for penile prosthesis surgery teaching and training that experts consider suitable for skill acquisition. Because specific validated guidelines and questionnaires for the validation and verifications of 3D simulators for penile surgery are not available, a modified questionnaire was used. CONCLUSION: The current 3D model for penile prosthesis surgery shows promising results regarding anatomic properties and suitability to train surgeons to perform penile implant surgery. The possibility of having an ethical, easy-to-use model with lower costs and limited consequences for the environment is encouraging for further development of the models.

Current devices, outcomes, and pain management considerations in penile implant surgery: an updated review of the literature.

Penile prosthesis surgery is a definitive treatment for erectile dysfunction (ED). The two categories of penile prosthesis are endorsed by professional guidelines, inflatable penile prosthesis (IPP) and malleable penile prosthesis (MPP). Each modality of penile prosthesis offers distinct advantages and incorporates specific design features, allowing for personalized device selection that aligns with individual needs and preferences. While the overall complication rate of penile implant surgery remains low, surgeons should maintain a high index of suspicion for complications in the perioperative time period. Multimodal analgesic regimens including nerve blocks and narcotic-free pathways should be administered to manage perioperative pain. Finally, the high patient satisfaction after penile prosthesis surgery underscores the success of this ED treatment option.

Penoscrotal approach for inflatable penile prosthesis implant: why it should be preferred.

INTRODUCTION: Inflatable penile prosthesis are the definitive treatment for erectile dysfunction. The two most used surgical approaches to position the implants are the penoscrotal and the infrapubic. Current trends showed that the penoscrotal approach is extensively preferred however, there is not conclusive evidence demonstrating the superiority of one technique over the other. The aim of this review is to summarize the scientific evidence available and to underline strengths and weaknesses of the two techniques. EVIDENCE ACQUISITION: We conducted a comprehensive search of MEDLINE, Cochrane Library, and National Center for Biotechnology Information PubMed to identify relevant published articles. The included studies had to explicitly examine the use of three-piece inflatable penile prosthesis with a focus on the surgical access method and complications. EVIDENCE SYNTHESIS: Twenty-six articles were included in the review: seven narrative reviews, five retrospective observational studies, five prospective observational studies, and nine mixed methodology studies. The most frequent approach was the penoscrotal, which was also found more comfortable (RG1) by the operators in one study. The infrapubic approach lasts less and one study demonstrated higher satisfaction by the patients. CONCLUSIONS: There is no evidence of significant differences in complications among the penoscrotal and infrapubic approaches. While the infrapubic approach is faster and patients were more satisfied, the penoscrotal approach is the most used by far. This is likely related to the more straightforward procedure through this access and the excellent surgical field exposure. For these reasons, it is also preferred in the most complex cases.

Revisión sistemática de la implantación de prótesis de pene en cirugía mayor ambulatoria / Systematic review of the implantation of penile prosthesis in major ambulatory surgery

Introducción y objetivo La implantación de prótesis deZ pene (PP) es una alternativa eficaz para la disfunción eréctil. Aunque inicialmente la cirugía de PP se realizaba en régimen hospitalario, existe una tendencia creciente a realizar el implante de PP en un modelo de cirugía mayor ambulatoria (CMA). El objetivo de este estudio es realizar una revisión sistemática de la literatura para identificar la evidencia disponible sobre la implantación de PP en el marco de la CMA en comparación con el procedimiento realizado en régimen hospitalario. Material y métodos Se realizó una búsqueda en las bases de datos electrónicas PubMed, EMBASE, Cochrane Library y MEDES y en los suplementos no indexados de los congresos científicos para identificar artículos relacionados con la implantación quirúrgica de PP en CMA hasta febrero de 2021. Los términos de búsqueda incluyeron prótesis de pene, disfunción eréctil, cirugía ambulatoria, atención ambulatoria y cirugía. Resultados Entre las 171 publicaciones obtenidas (51 en PubMed, 73 en EMBASE, 3 en Cochrane, 2 mediante MEDES y 42 mediante búsqueda manual), se seleccionaron finalmente 5 estudios. No hubo diferencias significativas entre la CMA y el régimen hospitalario en términos del tipo de dispositivo, el abordaje quirúrgico o la ubicación del reservorio. Las tasas de complicaciones observadas en ambos grupos fueron similares. La implantación de PP en régimen de CMA supuso un menor coste que la cirugía en régimen hospitalario y se asoció con tasas aceptables de satisfacción de los pacientes y un adecuado control del dolor. Conclusiones Los estudios demostraron que la implantación de PP en régimen de CMA puede lograr resultados similares en términos de seguridad y satisfacción a la implantación de PP en el régimen hospitalario, pudiendo también reducir los costes y mejorar la eficiencia. Esta investigación podría ayudar a los responsables de la toma de decisiones a extender la cirugía de PP al régimen ambulatorio (AU)

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 in 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 provide support decision makers to extend PP surgery into the ambulatory setting (AU)

Prótesis penianas: descripción de una serie de implantes con y sin dilatación de cuerpos cavernosos / Penile prostheses: Description of a series of implants with and without dilatation of the corpora cavernosa

INTRODUCCIÓN: El implante de prótesis penianas (PP) es el tratamiento de elección en la disfunción eréctil (DE) refractaria. Tiene una alta tasa de satisfacción (75-100%) y una tasa de complicaciones que varía entre el 2,1-28,8%. La técnica quirúrgica estándar incluye la dilatación de los cuerpos cavernosos (CC) previo a la inserción de los cilindros. Este procedimiento requiere tiempo y es el paso crítico para la ocurrencia de complicaciones. El objetivo de este estudio es describir los resultados de una serie de PP implantadas utilizando las técnicas con y sin dilatación de los CC. MATERIALES Y MÉTODOS: Ciento veinte pacientes con DE refractaria en quienes fue implantada una PP por 2 cirujanos en diferentes centros. Se evaluaron comorbilidades, características operatorias, satisfacción y complicaciones postoperatorias. RESULTADOS: El promedio de edad fue de 61±9,6 años. Las comorbilidades más prevalentes fueron: antecedente de prostatectomía radical, hipertensión arterial y diabetes mellitus. Se instalaron 42 prótesis maleables y 78 hidráulicas. Once pacientes habían tenido previamente una PP. La mediana de tiempo operatorio fue de 70 minutos (35-140). La satisfacción reportada fue de un 95,8%. Diez pacientes presentaron complicaciones. En el grupo en que la cirugía se realizó sin dilatación de los CC (n=80), el tiempo operatorio fue menor que en quienes sí se realizó dilatación de los CC (62,5minutos [35-105] versus 90 minutos [60-140], respectivamente, p < 0,0001). No hubo diferencia en la ocurrencia de complicaciones (p = 0,73) ni en los niveles de satisfacción (p = 0,196) al comparar la técnica con y sin dilatación de los CC. CONCLUSIÓN: En nuestra serie se evidenció un menor tiempo operatorio con la técnica sin dilatación de CC, pero no hubo diferencias en las complicaciones encontradas. Se requiere un estudio prospectivo y aleatorizado para hacer recomendaciones respecto a la dilatación de los CC

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

Opciones quirúrgicas de implante en pacientes con fibrosis peneana por infección o explantes previos / Surgical implant options in patients with penile fibrosis due to infection or previous explants

La fibrosis peneana por infección y/o explantes de prótesis peneanas previas condiciona situaciones de alta dificultad quirúrgica.

En este artículo se revisan las principales alternativas quirúrgicas en estos casos

Penile fibrosis due to previous penile infection and/or prosthesis explants entails situations of high surgical complexity. In these cases, reimplantation should follow an alternative scheme, aimed at minimizing perioperative and postoperative complications, as well as achieving maximum efficiency of the procedure and greater postoperative satisfaction of the patient and his partner. This article reviews the main surgical alternatives for these cases

Cirugía de prótesis peneana: indicaciones y técnica infrapúbica / Infrapubic surgical approach for penile prosthesis surgery: Indications and technique

CONTEXTO: El implante de prótesis de pene es actualmente el tratamiento más resolutivo para la disfunción eréctil tras la ineficacia o contraindicación del tratamiento farmacológico. Son muchas las vías de abordaje descritas para su implante, prevaleciendo en la actualidad la vía escrotal, la infrapúbica y la subcoronal. OBJETIVOS: Describir la técnica quirúrgica del abordaje infrapúbico, evaluar sus indicaciones, complicaciones y valorar sus ventajas y desventajas respecto al abordaje escrotal. ADQUISICIÓN Y SÍNTESIS DE LA EVIDENCIA: Se realizó una búsqueda de publicaciones desde el año 1983 hasta la actualidad en bases de datos (Medline PubMed y Cochrane Library) siguiendo los criterios PRISMA. Dieciséis artículos fueron incluidos: 4 prospectivos, 4 retrospectivos, una revisión sistemática, una ensayo aleatorizado, un artículo original, 5 artículos de opinión/descripción de técnica quirúrgica. DISCUSIÓN: Según los artículos revisados, actualmente el abordaje más usado es el escrotal. Aun así, la vía infrapúbica es una técnica más rápida y con tendencia a reducir el tiempo de retorno a la actividad sexual. Las tasas de complicaciones son escasas, teniendo cifras similares al abordaje escrotal, sin haberse recogido casos de hipostesia del glande y con tasas de infección inferiores al 3%. Además, cuenta con cifras de satisfacción elevadas, superando el 80%. CONCLUSIONES: El implante de prótesis de pene requiere de una familiarización con los diferentes abordajes quirúrgicos para adaptar cada técnica a cada caso. La vía infrapúbica, a pesar de no ser la más empleada, es igual de válida que la vía escrotal para el implante de prótesis de pene de 3 componentes, siendo eficaz, segura y con altas tasas de satisfacción para los pacientes y sus parejas

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

Implante de prótesis con reconstrucción y agrandamiento de pene en el mismo acto quirúrgico / Enlargement of length and girth associated with implantation of penile prostheses

INTRODUCCIÓN: La reducción en el tamaño del pene se debe a numerosas afecciones, incluida la enfermedad de Peyronie, cirugías previas de pene, diabetes, traumatismos, disfunción eréctil, cirugía pélvica y envejecimiento. La elasticidad de la túnica albugínea se ve afectada negativamente por cualquiera de las anteriores. Posteriormente, la fibrosis desencadena disfunción eréctil de manera progresiva. OBJETIVOS: Cuando se indica una prótesis de pene es importante determinar si el tamaño de este ha sido disminuido previamente. Debido a que una prótesis solo proporciona rigidez axial y no está asociada con el agrandamiento del pene, se recomienda el estudio de estrategias para aumentar el tamaño del pene de manera simultánea. MATERIAL Y MÉTODOS: Se realizó una revisión sistemática de la literatura científica actual sobre los procedimientos y tácticas disponibles actualmente para los implantes de pene y el aumento de su tamaño. RESULTADOS: La literatura demuestra que la evolución de la cirugía de implante de pene con aumento de su tamaño en un mismo acto quirúrgico ha evolucionado a través de 5 técnicas fundamentales: incisión con injerto; deslizamiento (en inglés: Sliding technique); deslizamiento modificada sin injerto (MoST, por sus siglas en inglés); la técnica de rebanada, o múltiples cortaduras (MUST, por sus siglas en inglés); y la técnica Egydio para los Procedimientos de Expansión de Túnica (en inglés: Egydio Tunica Expansion Procedure Strategy, o por sus siglas: TEP), una evolución adicional de las estrategias previas para lograr el implante de pene de última generación con un aumento máximo de su tamaño en un mismo acto quirúrgico. La evolución en la tecnología de los procedimientos de expansión tejidual ha llevado a la disminución del tamaño de los defectos de la túnica y a evitar los injertos para prevenir el abultamiento y las indentaciones, al tiempo que desarrolla soluciones para preservar la fuerza de la túnica albugínea para el posicionamiento firme de los cilindros en el interior de los cuerpos cavernosos. CONCLUSIONES: La evolución de estas técnicas supone la transformación de defectos de túnica más grandes en defectos más pequeños. Mientras que los injertos se usan a menudo para reforzar la estructura del pene secundaria a defectos grandes, las incisiones múltiples de la túnica albugínea están ganando popularidad para recuperar el calibre y la longitud sin necesidad de injerto y sin la pérdida de la firmeza que requiere la túnica para soportar los cilindros dentro de los cuerpos

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

Prótesis de pene inflable de 3 componentes: emplazamiento ectópico del reservorio / Three-piece inflatable penile prosthesis: Ectopic reservoir placement

INTRODUCCIÓN: Las complicaciones asociadas al emplazamiento del reservorio son infrecuentes pero pueden ser potencialmente graves, motivo por el cual se han desarrollado alternativas técnicas para el emplazamiento en lugares diferentes al habitual (ectópico). El objetivo de este trabajo es revisar, de acuerdo con la evidencia disponible, las diferentes opciones para el emplazamiento ectópico del reservorio. MATERIAL Y MÉTODO: Revisión narrativa basada en una búsqueda bibliográfica de artículos relevantes indexados en PubMed, en inglés o castellano, publicados en el periodo 2000-2019, empleando las palabras clave: «prótesis de pene», «reservorio ectópico», «prostatectomía radical», «cistectomía radical», «radioterapia pélvica» y «trasplante renal». Se descartaron los artículos no originales, casos aislados y revisiones. Se revisaron un total de 11 trabajos. RESULTADOS: Las alteraciones de la anatomía de la pelvis tras cirugía o radioterapia generan una dificultad añadida al emplazamiento del reservorio. Para minimizar el riesgo de complicaciones se han modificado los dispositivos y las técnicas que permiten el emplazamiento submuscular. La evidencia relativa a funcionalidad y complicaciones se limita a series retrospectivas, de instituciones únicas, bajo volumen y escaso seguimiento. La funcionalidad es adecuada con los dispositivos adaptados; las complicaciones, infrecuentes y de escasa gravedad. CONCLUSIONES: Aunque la evidencia es baja, el emplazamiento ectópico del reservorio puede considerarse una técnica segura, eficaz y reproducible. Además, puede resultar particularmente útil en casos de anatomía pélvica alterada

INTRODUCTION: The complications associated to the placement of the reservoir are infrequent but potentially serious. Therefore, technical alternatives have been developed for the performance of the procedure in different locations (ectopic). The aim of this review is to revise the evidence available on the different options for the ectopic placement of the reservoir. MATERIAL AND METHOD: Narrative review based on a bibliographical search limited to PubMed- indexed relevant manuscripts, in Spanish or English, for the period 2000-2019, using «penile prosthesis», «ectopic reservoir», radical prostatectomy», «radical cystectomy», «pelvic radiotherapy», and «renal transplantation» as key words. Non original articles and reviews were not considered eligible. A total of 11 manuscripts were included. RESULTS: Pelvic alterations after surgery and/or radiotherapy increase the difficulty in the placement of the prosthesis reservoir. In order to minimize the risk of complications, different modifications have been performed on the devices, and technical innovations have been developed for the submuscular placement of the reservoir. The available evidence regarding the functionality and complications of these techniques is limited to single institution, low volume, and retrospective series with short follow-up periods. The functionality seems to be adequate using the adapted devices. The complications are infrequent and mild in severity. CONCLUSIONS: Although the available evidence is still limited, the ectopic placement of the reservoir may be considered a safe, effective, and reproducible technique. In addition, it may result particularly useful in cases of altered pelvic anatomy

Implante de prótesis peneana: indicaciones y abordaje penoescrotal / Penile prosthesis surgery: Indications and penoscrotal approach

La prótesis de pene inflable se desarrolló en 1973 como tratamiento definitivo para la disfunción eréctil. Desde entonces, estos dispositivos protésicos han sufrido grandes modificaciones, produciendo avances científicos y tecnológicos, mejorando la fiabilidad, la longevidad y los resultados quirúrgicos. La implantación quirúrgica de una prótesis de pene puede considerarse en pacientes con disfunción eréctil que no responden a la farmacoterapia o que prefieren una solución permanente a su problema. De acuerdo con las Directrices de la EAU (2019), independientemente de la indicación, y con base en una evaluación adecuada, la implantación de prótesis tiene una de las tasas de satisfacción más altas (92-100% en pacientes y 91-95% en parejas) entre las opciones de tratamiento para la disfunción eréctil. El acceso penoescrotal es el más común, utilizado en > 80% de los implantes de prótesis de pene inflable en todo el mundo. Las quejas y casos de insatisfacción tras la cirugía de prótesis de pene inflable más frecuentes se deben a problemas técnicos o resultados quirúrgicos deficientes, como la longitud final del pene. Es necesario incrementar la información que recibe el paciente en el ámbito preoperatorio de la cirugía de prótesis de pene inflable, incluyendo el manejo de altas expectativas, y debemos ser cuidadosos a la hora de elegir a los pacientes adecuados para el tratamiento definitivo

Inflatable penile prosthesis was developed in 1973 as a definitive treatment for erectile dysfunction. Since then these prosthetic devices underwent huge modifications, and scientific and technologic advances were accomplished, improving reliability, longevity and the surgical outcomes. Surgical implantation of a penile prosthesis may be considered in patients with erectile dysfunction who do not respond to pharmacotherapy or who prefer a permanent solution to their problem. According to the 2019 EAU Guidelines, regardless of the indication, prosthesis implantation has one of the highest satisfaction rates (92-100% in patients and 91-95% in partners) among the treatment options for erectile dysfunction based on appropriate consultation. The penoscrotal handling is the most common approach accounting for >80% of inflatable penile prosthesis placed worldwide. Most frequent complaints and dissatisfaction with inflatable penile prosthesis are related to technical issues or poor surgical outcomes such as the final length of the penis. There is an urgent need to improve the patient awareness in inflatable penile prosthesis in the preoperative arena, including the high expectation management, and an effort to select the proper patients for definitive treatment

Modern treatment strategies for penile prosthetics in Peyronie's disease: a contemporary clinical review / 亚洲男科学杂志(英文版)

Peyronie's disease is a common condition resulting in penile deformity, psychological bother, and sexual dysfunction. Erectile dysfunction is one common comorbid condition seen in men with Peyronie's disease, and its presence significantly impacts treatment considerations. In a man with Peyronie's disease and significant erectile dysfunction who desires the most reliable treatment, penile prosthesis placement should be strongly considered. In some instances, such as those patients with relatively mild curvature, prosthesis placement alone may result in adequate straightening. However, many patients will require additional straightening maneuvers such as manual modeling, penile plication, and tunica albuginea incision with or without grafting. For patients with severe penile shortening, penile length restoration techniques may also be considered. Herein, we provide a comprehensive clinical review of penile prosthesis placement in men with Peyronie's disease. Specifically, we discuss preoperative indications, intraoperative considerations, adjunctive straightening maneuvers, and postoperative outcomes.

Pain management strategies in penile implantation / 亚洲男科学杂志(英文版)

The opioid epidemic continues to be a serious public health concern. Many have pointed to prescription drug misuse as a nidus for patients to become addicted to opioids and as such, urologists and other surgical subspecialists must critically define optimal pain management for the various procedures performed within their respective disciplines. Controlling pain following penile prosthesis implantation remains a unique challenge for urologists, given the increased pain patients commonly experience in the postoperative setting. Although most of the existing urological literature focuses on interventions performed in the operating room, there are many studies that examine the role of preoperative adjunctive pain medicine in diminishing postoperative narcotic requirements. There are relatively few studies looking at postoperative strategies for managing pain in prosthetic surgery with follow-up past the immediate hospitalization. This review assess the various strategies employed for managing pain following penile implantation through the lens of the current state of the opioid crisis, thus examining how urologists can responsibly treat pain without contributing to the growing threat of opioid addiction.

Updates in penile prosthesis infections / 亚洲男科学杂志(英文版)

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