Double distal corporal anchoring stitch for lateral penile implant cylinder extrusion.

BACKGROUND: The ventral and distal aspects of the corpora cavernosa are the thinnest, increasing the likelihood of cylinder extrusion or crossover complications pertaining to inflatable penile prosthesis procedures. A double distal corporal anchoring double stitch can be used to robustly secure impending lateral extrusions and crossovers of implant cylinders. It is a novel, effective corrective measure for the uncommon complication of migrated cylinders in inflatable penile prosthesis placement. AIM: To describe the surgical indications and technique for the double distal corporal anchoring fixation stitch for lateral penile implant cylinder extrusion. METHODS: We discuss a double-stitch technique that is performed following corporoplasty and capsulotomy. A lateral incision is made subcoronally on the affected side to identify the crossover or lateral extrusion. The cylinder is repositioned properly within the native corpora to prevent further cylinder migration. Two 2-0 Ethibond sutures are threaded through the distal cylinder eyelet, and each suture is delivered through the glans with a Keith needle and tied off. An incision is made in the glans, and 1 arm of each suture is tied with the other to create a bridge between the sutures that can be positioned deep within the skin of the glans. OUTCOMES: Over the past 4 years, 66 patients with lateral cylinder extrusion underwent the double distal corporal anchoring fixation stitch procedure, with overall improved satisfaction (97%). Only 2 patients had surgical complications. One patient experienced repeated lateral extrusion of the penile implant cylinders 6 weeks following the double-anchoring stitches procedure. The second patient developed a painful suture granuloma that necessitated excision, which resolved this issue, and the penile implant cylinder remained in the proper position over a year later. CLINICAL IMPLICATIONS: This technique ensures the secure fixation of the affected cylinders in the surgical capsule by creating a bridge between 2 sutures holding each repositioned cylinder in place, and the ensuing fibrotic reaction helps to fixate the extruded cylinder within the midglandular tissue. STRENGTH AND LIMITATIONS: This surgical technique describes the double distal corporal anchoring stitch for lateral penile implant cylinder extrusion. Further studies are warranted to validate long-term outcomes and satisfaction. CONCLUSION: The double distal corporal anchoring fixation stitch is a safe and efficacious method to secure cylinders in the proper surgical capsule during revision procedures to correct distal crossovers or laterally extruded penile prosthesis implants.

The role of imaging in patients with corporal fibrosis undergoing penile prosthesis placement: a narrative review.

Penile prosthesis implantation (PPI) is a definitive solution for severe erectile dysfunction unresponsive to conventional therapies. However, in patients with corporal fibrosis (CF), the procedure presents significant challenges and higher complication risks. This narrative review explores the crucial role of imaging techniques, such as ultrasound and magnetic resonance imaging, in preoperative planning for PPI in patients with CF. Through a comprehensive literature search, we analyzed studies focusing on the efficacy of these imaging modalities in assessing fibrosis severity and guiding surgical strategies. Our findings highlight that advanced imaging provides essential insights into fibrosis extent, thereby optimizing surgical outcomes and reducing potential complications. The review underscores the importance of meticulous preoperative imaging in improving patient management and surgical precision in this complex clinical scenario.

Management of Infections Associated with Penile Prostheses and Artificial Urinary Sphincters.

Prosthetic urology can substantially enhance the quality of life for patients. However, it is not without challenges. Infections of penile prostheses and artificial urinary sphincters are often difficult to diagnose, manage, and treat. Over time, device improvements, refined surgical methods, better understanding of microbiology, and biofilms in combination with higher sterility standards and protocols, have significantly reduced the rates of infection. Here, the authors offer a comprehensive overview of prosthetic urologic infections and their management in the current era.

Outcomes related to penile prosthesis reservoir removal: a 7-year multi-institutional experience.

BACKGROUND: The 3-piece inflatable penile prosthesis (IPP) is the most widely used device for erectile dysfunction refractory to medications, containing a reservoir inserted into the retropubic space (RPS) or an alternative/ectopic space (AES). Indications for removal of the reservoir include malfunction, malposition, or infection. In revision cases without infection, reservoir removal is sometimes optional. AIM: We reviewed outcomes and complications related to reservoir removal from a large multi-institutional series. METHODS: We retrospectively reviewed databases at 6 institutions over 7 years. Patients with artificial urethral sphincter, urethral sling, or mini-jupette were excluded. OUTCOMES: Outcomes and complications related to IPP reservoir removal were analyzed. Data were collected, but only reservoir-related complications at surgery were included. Data were compared between the RPS and AES cohorts to evaluate differences with a χ2 test, with significance at P < .05. RESULTS: Of 215 cases, there were 172 RPS and 43 AES reservoirs. The mean patient age was 65.3 years. An overall 131 procedures were due to malfunction and 49 to malposition of an IPP component; 35 were secondary to infection. Among those retained (n = 44), reasons included reuse, avoiding surrounding structure damage, and difficult dissection. Among those removed (n = 171), 15 required a counterincision. To determine the statistical difference between those removed from the RPS and an AES, the χ2 test result was P = .00059, indicating a significant difference in the need for a counterincision between the groups. Complications included bladder perforation (n = 1) in the RPS group and an avulsion of the epigastric vessels requiring abdominal exploration (n = 1) in the AES group. To determine the statistical difference between RPS and AES complications, the χ2 test result was P = .365, indicating no significant difference between the groups. STRENGTHS AND LIMITATIONS: Strengths include being a multi-institutional study with high-volume skilled implanters. Limitations include being a retrospective review, with implanters exclusively performing penoscrotal incisions and not utilizing an infrapubic approach. Last, there was a lack of long-term follow-up with these patients. CONCLUSIONS: Removal of an IPP reservoir remains safe, with few intraoperative complications. Surgeons should be aware of the inferior epigastric vessels during removal in an AES or be willing to perform a counterincision to avoid injury to surrounding structures. Surgeons should also obtain preoperative imaging to identify the specific location of the reservoir and adjacent anatomy. This is the first multi-institutional study reviewing outcomes related to reservoir removal during IPP revision or removal surgery.

A narrative review on synchronous concurrent versus delayed sequential surgery in the artificial urinary sphincter and penile prosthesis implantation.

Background and Objective: In a patient who complains of both stress urinary incontinence (SUI) and erectile dysfunction (ED), prosthetic surgery with a urinary continence device and penile prosthesis implant can offer a definitive solution to address both problems. The AMS 800 artificial urinary sphincter (AUS) device is considered the standard of care to restore SUI while the inflatable penile prosthesis (IPP) device is thought to be superior to a malleable prosthesis to provide a more natural penile erection with higher patient satisfaction rates. The following article explores the current understanding of AMS 800 AUS surgery and IPP device in treating males with concurrent SUI and ED as well as evaluates the advantages and disadvantages of concurrent synchronous dual vs. delayed or staged device implantation. Methods: The available literature on AUS and IPP implantation was reviewed on PubMed and Embase databases between 1 January 2000 and 1 December 2022. This narrative review evaluates relevant key features pertaining to prosthetic surgery with an emphasis on arguments for concurrent synchronous dual vs. delayed sequential surgery for AUS and IPP devices. Additionally, this paper provides a brief surgical description of the techniques and potential complications relating to both prosthetic procedures. Key Content and Findings: While a great deal is known about the excellent outcomes of both AUS and IPP implantation, there is limited literature published on the outcomes of dual AUS and IPP surgery. The decision to proceed with concurrent synchronous dual vs. delayed sequential two-stage implants is likely determined by the patient's preference, the surgeon's expertise, and the availability of prostheses. In either situation, patients should be counselled regarding the advantages and disadvantages of undergoing synchronous concurrent vs. delayed sequential implants and associated surgical challenges are likely dependent on the patient's anatomy and the surgeon's preference. Conclusions: For carefully selected patients with SUI and ED, dual implantation of AUS and IPP provides a definitive treatment to address both conditions at the same time. Patients should be counselled regarding the advantages and disadvantages of synchronous concurrent vs. sequentially delayed implants while technical considerations regarding the sequence of prosthetic device surgery are likely dependent on the patient's factors and the surgeon's preference and surgical expertise.

A global, propensity-score matched analysis of patients receiving inflatable penile prostheses and the risk of complications, infections, and re-interventions.

Background: Over 25,000 men undergo inflatable penile prosthesis (IPP) placement yearly to treat erectile dysfunction (ED). Although various comorbidities are hypothesized risk factors for complications, this remains incompletely understood. Our objective was to utilize multi-institutional data to characterize risk for reintervention, complications, and infections in patients with common suspected risk factors undergoing IPP placement. Methods: We queried the TriNetX database for adult men who underwent IPP placement from 2003-2023 utilizing Current Procedural Terminology (CPT) codes. We examined the impact of diabetes mellitus (DM), hypertension (HTN), nicotine use, radiation therapy (RT), radical prostatectomy (RP), and urethral surgery [urethroplasty, artificial urinary sphincter (AUS), male urethral sling (MS)] on clinical outcomes defined by International Classification of Diseases 10th Revision (ICD-10) codes. Our primary outcome was need for reintervention based on CPT codes. Secondary outcomes included overall rates of complication and infection utilizing ICD-10 codes. Analytics were performed using TriNetX to calculate risk ratios (RRs) and Kaplan-Meier (KM) survival. We evaluated outcomes overall and for each individual comparison cohort using the remaining demographic variables to perform propensity score matching (PSM). Results: In a total of 11,026 patients there was an overall 13.5% risk of undergoing at least one reintervention, with some undergoing multiple based on CPT codes. KM analysis showed a median IPP survival of 18.2 years and a projected 10- and 20-year survival probability at 70.6% and 48.4% respectively. Overall complication rate was 19.3% with a 5.2% rate of infection based on ICD codes. Patients with history of urethral surgery were at higher risk of both IPP complication and re-intervention. When further analyzing type of re-intervention, patients with a history of smoking, prior RP, and prior AUS/MS placement had higher rates of device removal. Patients with a history of diabetes were less likely to undergo IPP replacement at the time of explant. There were no identified risk factors for IPP infection. Conclusions: This is the largest cohort of patients ever evaluated and can help guide patient selection and counseling. There was a higher rate of IPP complications than previously reported, but this may be due to different reporting parameters. History of prior urethral surgery conferred a higher risk of complications and re-intervention. These results can help guide patient selection and counseling.

Perioperative infection prevention during inflatable penile prosthesis surgery: a narrative review.

Background and Objective: Penile prostheses are an option for the management of erectile dysfunction (ED). Over the years penile prosthesis surgery has become increasingly safe owing to improvements such as antibiotic usage, coated devices, and surgical techniques. However, infection remains a dreaded complication during prosthesis surgery. Efforts to minimize risk of infection in the perioperative period have been extensively studied. Herein, we performed a narrative review on preoperative, intraoperative, and postoperative strategies for infection prevention during placement of a penile prosthesis with a comparison of infection prevention strategies to other surgical fields. Methods: A literature review was performed using PubMed and Google Scholar. Studies evaluating perioperative management of penile prosthesis infection were included. The following search terms were used to for our literature search: penile prosthesis, inflatable penile prosthesis, infection, prevention, perioperative management. Articles were graded based on the 2011 Oxford Centre for Evidence Based Medicine (OCEBM) guidelines and a table was generated with each intervention discussed and its level of evidence based on current literature. Key Content and Findings: Optimization of patient's comorbid conditions can help reduce risk during prosthesis operations. Monitoring and optimizing a patient's glycemic control has been investigated, but the current literature does not necessarily support a strict hemoglobin A1c (HbA1c) or pre-operative blood glucose level. Surgical field preparation using chlorhexidine-based solutions has been shown to be superior to iodine-based solutions. Appropriately selected peri-operative antibiotics have also been shown to reduce infection risk. Intraoperatively, the use of coated devices in addition to a 'no touch' technique have been shown to significantly reduce the risk of inflatable penile prosthesis (IPP) infection. Post operatively, available evidence of antibiotic use has not been demonstrated to be effective in reducing infection rates. Conclusions: Surgical infection following placement of an IPP is a devastating and morbid complication with infection rate up as high as 1-3% in virgin cases and 7-18% in revision cases. While perioperative techniques exist and have reduced risk of infection, more prospective data is needed to evaluate the clinical significance of these different approaches. More research in these areas, along with future options such as nanoparticles, antibiotic coated suture, and next generation sequencing (NGS) for bacterial pathogens, may shed light on further ways to optimize infection reduction strategies for prosthesis surgery.

Contemporary management of ischemic priapism: A 12-year population-based analysis from a large US database.

BACKGROUND: Priapism is a urological condition characterized by a persistent erection. The management varies based on its subclassifications. Despite established clinical guidelines for ischemic priapism, there is a lack of large-scale research focused on patient characteristics and management strategies. OBJECTIVES: To analyze the contemporary management of ischemic priapism in the US, exploring patient demographics and clinical characteristics, as well as predictors of erectile dysfunction (ED) and penile prosthesis implantation (PPI). MATERIALS AND METHODS: We performed a retrospective analysis of the PearlDiver Mariner database, reviewing records from 2010-2021. Adult males diagnosed with ischemic priapism were included. Data analysis covered demographic, clinical variables, and management strategies. Predictors of de novo ED and PPI were evaluated using multivariable logistic regression analysis. RESULTS: Of 36,120 patients, most (93%) received only medical management, and a minority underwent surgical interventions (penile shunt surgery [PSS], PPI or both). Medical management was typically effective, as 67.08% of the patients in this group experienced only one episode of priapism. However, de novo ED occurred in 16.57% of these patients. The majority of patients undergoing PPI had an inflatable prosthesis (81%). Older age (odds ratio, OR 1.02), the presence of metabolic diseases (OR 1.39), neurogenic disorders (OR 1.72), solid pelvic malignancies (OR 1.09), and multiple episodes of priapism were identified as significant predictors of de novo ED (all p < 0.05). Similarly, age (OR 1.03), the presence of metabolic diseases (OR 1.23), solid pelvic malignancies (OR 1.99), and multiple episodes of priapism were associated with higher likelihood of PPI (all p < 0.05). CONCLUSION: Most cases of ischemic priapism are managed with the medical therapy. Less than 3% of patients with ischemic priapism receive PPI, and when this occurs an inflatable prosthesis is favored. Age, specific comorbidities, and multiple episodes of priapism appear to be significant predictors of ED and PPI.

Changing trends in penile prosthesis implantation in China and an overview of postoperative outcomes from a single center.

BACKGROUND: Surgical penile prosthesis implantation (PPI) procedures have only recently been introduced to mainland China, with the overall number of such procedures having been conducted to date remaining relatively low. Accordingly, relatively little remains known with respect to the annual trends in PPI. Accordingly, this study was developed with the goal of clarifying these trends across different hospitals in mainland China, while also providing a single-center overview of post-PPI patient outcomes. RESULTS: To identify males in mainland China who had undergone PPI, a retrospective review of data from January 2019 - October 2023 was conducted. This approach revealed an increase in the total PPI caseload from 120 in 2019 to 413 within the first 10 months of 2023. Over this same interval, the number of surgeons performing PPI rose from 33 to 74. A retrospective review of the 112 patients who had undergone PPI at Shanghai General Hospital from 2019-2023 revealed that these patients had a median age of 39 [27-63] years, and PPI treatment led to a significant increase in median International Index of Erectile Function-5 (IIEF-5) scores from a baseline value of 10.23 ± 1.26 to a post-treatment value of 22.6 ± 2.73. The underlying causes of erectile dysfunction for these patients included vasculogenic factors (58/112; 51.8%), diabetes mellitus (21/112; 18.8%), and injuries to the spinal cord or pelvis (14/112; 12.5%). The overall rates of satisfaction with the PPI reported by patients and their partners were 93.0% and 90.4%, respectively, and the 3-year PPI survival rate for this cohort was 87%. CONCLUSION: These data highlight a rising trend in the number of PPI being performed in China, with these steadily increasing rates since 2019 emphasizing the increasingly high levels of acceptance of this procedure by patients and clinicians as a means of treating erectile dysfunction. However, the expertise is restricted to a small number of surgeons. Even so, it is a safe and efficacious approach to managing severe erectile dysfunction for patients in China, and when performed by experienced surgeons based on standardized protocols, low complication rates can be achieved while providing patients and their sexual partners with high levels of satisfaction.

RéSUMé: CONTEXTE: Les procédures chirurgicales d'implantation de prothèses péniennes (IPP) n'ont été que récemment introduites en Chine continentale, le nombre total de procédures de ce type ayant été effectuées à ce jour restant relativement faible. On ne sait donc encore que relativement peu de choses sur les tendances annuelles de l'IPP. La présente étude a été développée dans le but de clarifier ces tendances dans différents hôpitaux de Chine continentale, tout en fournissant une vue d'ensemble des résultats des patients post-IPP dans un seul centre. RéSULTATS: Afin d'identifier les hommes de Chine continentale qui avaient subi un IPP, une recherche rétrospective des données a été effectuée de janvier 2019 à octobre 2023. Cette approche a révélé une augmentation du nombre total de cas d'IPP de 120 en 2019 à 413 au cours des 10 premiers mois de 2023. Au cours de cette même période, le nombre de chirurgiens pratiquant des IPP est passé de 33 à 74. L'étude rétrospective des 112 patients qui avaient subi un IPP à l'hôpital général de Shanghai de 2019 à 2023 a révélé qu' ils avaient un âge médian de 39 [27­63] ans, et que le traitement par IPP a entraîné une augmentation significative des scores médians de l'indice international de la fonction érectile-5, qui sont passés d'une valeur de base de 10,2 ± 1,3 à une valeur post-traitement de 22,6 ± 2,7. Les causes sous-jacentes de la dysfonction érectile chez ces patients comprenaient des facteurs vasculogéniques (58/112; 51,8%), un diabète (21/112; 18,8%) et des lésions de la moelle épinière ou du bassin (14/112; 12,5%). Les taux globaux de satisfaction à l'égard de l'IPP, rapportés par les patients et leurs partenaires, étaient respectivement de 93,0% et 90,4%, et le taux de survie à 3 ans de l'IPP dans cette cohorte était de 87%. CONCLUSION: Ces données mettent en évidence une tendance à la hausse du nombre d'IPP pratiquées en Chine; ces taux en constante augmentation depuis 2019 soulignent les niveaux de plus en plus élevés d'acceptation de cette procédure par les patients et les cliniciens comme moyen de traitement de la dysfonction érectile. Cependant, l'expertise est limitée à un petit nombre de chirurgiens. Malgré cela, il s'agit d'une approche sûre et efficace pour gérer la dysfonction érectile sévère pour les patients en Chine, et lorsqu'elle est effectuée par des chirurgiens expérimentés sur la base de protocoles standardisés, de faibles taux de complications peuvent être atteints tout en offrant aux patients et à leurs partenaires sexuels des niveaux élevés de satisfaction.

Antibiotic dip and irrigation solutions confer increased antimicrobial efficacy of inflatable penile prosthesis hydrophilic surfaces compared with 0.05% chlorhexidine gluconate.

BACKGROUND: Chlorhexidine gluconate (CHG) (0.05%) has recently been suggested as both a dip for the hydrophilic surface and an irrigation solution in the setting of penile prosthesis (PP) surgery. AIM: The study sought to compare the antimicrobial efficacy of 0.05% CHG with vancomycin and gentamicin (VG) antibiotics as dip and/or irrigation solutions in the setting of a hydrophilic PP surface in vitro. METHODS: Sterile PPs with a hydrophilic coating were obtained. A series of experiments were performed to evaluate the efficacy of normal saline (NS), 0.05% CHG, or VG as dip and/or irrigation solutions to reduce methicillin-sensitive Staphylococcus aureus adhesion to PP surfaces. The 8-mm discs from PPs were incubated in 105 colony-forming units/mL of methicillin-sensitive S aureus for 48 hours, plated, and counted. Disc-diffusion tests were conducted by suspending 6-mm discs for 2 minutes in NS, 0.05% CHG, or VG, then placing them coated side down onto plates streaked with the following organisms: methicillin-sensitive S aureus, S epidermidis, Enterococcus, and Escherichia coli. After 24 hours of growth, zones of inhibition were measured. OUTCOMES: We found average bacterial counts (colony-forming units/mL) and zones of inhibition (mm) following a series of treatment protocols of PP discs. RESULTS: PP discs dipped in VG reduced bacterial adhesion to the implant surface >0.05% CHG (~5.5 log vs ~1.5 log; P < .01). Discs irrigated with either 0.05% CHG or NS removed all dip solution adsorbed to the hydrophilic surface, allowing bacterial growth. VG irrigation adsorbed to the hydrophilic surface even after 0.05% CHG or NS dips, reducing bacterial adherence (~3 log). Dipping and irrigating discs with VG was most effective in reducing adherent bacteria (~5.5 log) and was the only irrigation that showed antimicrobial activity. CLINICAL TRANSLATION: VG, when used both as a prophylactic dip and as an intraoperative irrigation solution for hydrophilic penile implant surfaces, has improved efficacy to 0.05% CHG and NS. STRENGTHS AND LIMITATIONS: This is the first study to compare the use of VG, 0.05% CHG, and NS as prophylactic dips and intraoperative irrigations for hydrophilic penile implant surfaces. Limitations include the use of in vitro studies, which serve as a proxy for in vivo practices and may not be entirely accurate nor translatable clinically. CONCLUSION: We demonstrated the superior efficacy of VG as a combined dip and irrigation solution for hydrophilic penile implant surfaces compared with 0.05% CHG.

Minocycline-rifampin-impregnated penile prosthesis surfaces retain antimicrobial activity following irrigation with 0.05% chlorhexidine gluconate and antibiotic solutions.

BACKGROUND: 0.05% Chlorhexidine gluconate (CHG; Irrisept [IrriMax]) is a commercial wound irrigation solution approved by the Food and Drug Administration that has seen recent adoption in the field of prosthetic urology; however, no study has evaluated whether 0.05% CHG is compatible with the minocycline-rifampin-impregnated surface (InhibiZone) of the AMS 700 penile prosthesis (Boston Scientific). AIM: To evaluate whether 0.05% CHG alters the antibiotic efficacy of the minocycline-rifampin-impregnated penile prosthesis surface. METHODS: Discs (8 mm) were taken by a punch biopsy (Sklar) from sterile penile prosthesis reservoirs whose surfaces had been impregnated with rifampin and minocycline. Discs (n = 10) were suspended in 0.05% CHG, vancomycin and gentamicin, or normal saline for 2 minutes to simulate intraoperative irrigation. Discs were then rinsed in normal saline to remove any unbound solution and incubated with methicillin-sensitive Staphylococcus aureus for 48 hours. Adherent surface bacteria were suspended by shaking in a 0.3% Tween 20 solution, serially diluted, plated onto 3M PetriFilms, and counted. Kirby-Bauer disc diffusion assays were conducted to generalize findings across various organisms. OUTCOMES: Outcomes included (1) bacterial adherence to the implant surface measured as bacterial counts (in colony-forming units per milliliter) and (2) bacterial growth reduction measured as zones of inhibitions (in millimeters). RESULTS: Incubation of implant surfaces in 0.05% CHG did not alter recovered bacterial counts as compared with normal saline and vancomycin/gentamycin. Similarly, within a single bacterial species, 0.05% CHG and vancomycin/gentamycin did not alter zone-of-inhibition measurements in Kirby-Bauer disc diffusion studies. CLINICAL TRANSLATION: This study demonstrates in vitro that 0.05% CHG may be used directly on the minocycline-rifampin-impregnated surface without altering the antibiotic efficacy of the coating. STRENGTHS AND LIMITATIONS: Strengths include that this is the first study to evaluate if 0.05% CHG affected the minocycline-rifampin-impregnated surface. Limitations include the use of in vitro studies, which serve as a proxy for in vivo practices and may not be entirely accurate or translatable in a clinical setting. CONCLUSION: 0.05% CHG does not alter the antimicrobial activity of the minocycline-rifampin-impregnated surface as compared with vancomycin/gentamycin and normal saline in vitro; however, its efficacy in clinical practice remains to be evaluated.

MR imaging of penile pathology and prostheses.

Penile MRI is a vital yet underutilized diagnostic tool that provides detailed information crucial for managing various penile pathologies. Due to its infrequent use, many radiology trainees lack confidence in interpreting these exams. This article reviews the anatomy, key technical considerations, and interpretive pearls for penile trauma, Peyronie's disease, priapism, penile neoplasms, prosthesis evaluation, and a few miscellaneous conditions. Through illustrative case examples, this review aims to enhance the understanding and proficiency of radiologists in performing and interpreting penile MRI in these clinical scenarios.

Erosion of IPP components into bladder lumen and prostatic urethra.

The incidence of erosion of inflatable penile prosthesis (IPP) components into adjacent organs is low (<0.1 %). During a transurethral resection of the prostate (TURP) in a patient with prior IPP placement, we encountered IPP tubing that had eroded into the prostate. The pump and cylinders were later explanted through a penoscrotal approach, with the reservoir drained and retained with plan for follow up cystoscopy in 4-6 weeks. Cystoscopy 1 month later demonstrated reservoir erosion into the bladder lumen. An open cystotomy was performed to retrieve the reservoir. This is the first reported case of IPP tubing eroding into the prostate.

Penile Prosthetic Pump Reservoir Mimicking a Cecal Subepithelial Mass.

Intestinal subepithelial lesions are often encountered during endoscopy. Etiologies can include lesions intrinsic or extrinsic to the gastrointestinal wall. They can present a diagnostic dilemma as simple mucosal biopsies are often nondiagnostic. The combination of characteristic radiographic, endoscopic, and endosonographic features can aid in a definitive diagnosis precluding the need for unnecessary tissue sampling of extrinsic compressive etiologies. The location of the space of Retzius which is the traditional site of penile prosthetic pump reservoir insertion can predispose to cecal compression. We present a rare case of a penile prosthetic pump reservoir presenting as a cecal subepithelial mass on endoscopy.

Long-term penile prosthesis couple's satisfaction: A systematic review and meta-analysis.

CONTEXT: Data supporting successful and satisfactory penile prosthesis (PP) implantation outcomes are mainly based on subjective, rather than objective, analysis. OBJECTIVE: To systematically review and objectively analyze, all available data related to patient and partner PP satisfaction. EVIDENCE ACQUISITION: An extensive search was performed, including the following key-words: ("penile prosthesis" and "satisfaction"). The search, which accrued data from January 1, 1969, up to July 31, 2023, was restricted to English-language articles including human participants. EVIDENCE SYNTHESIS: Out of 663 retrieved articles, 83 were considered including, 12,132 subjects with a mean age and mean follow-up of 58.6 [range 20; 77.1] years and 47.6 [range 6; 374] months, respectively. Overall, a high patient satisfaction rate was observed 83[80; 86]%. The satisfaction rate increased in subjects with three-piece PP and in those with a higher rate of cardiovascular or neurological diseases and was independent of the patient's age. Partner's satisfaction rate was lower when compared to that observed in men and it increased according to the use of inflatable devices and the presence of patient Peyronie's disease. The long-term complication rate was limited ranging from 3% for erosion to 4.6% when mechanical failure was considered. CONCLUSIONS: Patient and partner satisfaction is excellent and increases with time. The number of complications is limited and is strongly associated with the presence of diabetes mellitus. PATIENT SUMMARY: We found a high couple satisfaction score that was higher when reported by males compared to females. Patient satisfaction increased with time, and it was independent of age.

Penile prosthesis for erectile dysfunction in France: A six-year nationwide database analysis.

INTRODUCTION: Urological consultations for erectile dysfunction (ED) are increasing worldwide. Penile prosthesis (PP) implantations are performed when other treatments are unsuccessful. However, there is no data regarding PP implantations in France beyond the year 2016. OBJECTIVES: This study aimed to describe the changes in the number and type of PP implants used for the treatment of ED in France from 2016 to 2021 and the hospitalization rates following implantation using French national data from the Program for the Medicalization of Information Systems (PMSI). MATERIALS AND METHODS: We analyzed data on PP implantations in all France hospitals. PPs were coded into three types according to the Common Classification of Medical Procedures (CCAM). The number of patients admitted to hospital with complications twelve months after implantation was also recorded. RESULTS: During the study period, 3675 men received 3868 PPs in France. A gradual increase in the total number of implanted PPs was observed, with an overall increase of 33.8%. In 2020, there was a sharp decline in the number of implanted PPs, primarily owing to the COVID-19 pandemic. The most commonly used implant was PPs with an extracavernous compartment, comprising 85% of all PPs. Twelve months after implantation, only 1-2% of the patients were rehospitalized. CONCLUSION: PP implantation surgeries are highly reproducible and have a low incidence of complications, in terms of rehospitalization after one year of placement (1.8%). Moreover, there was an increase in the demand for penile prosthesis implantations in France between 2016 and 2021. LEVEL OF EVIDENCE: 4: Descriptive epidemiological study.

Assessing artificial intelligence responses to common patient questions regarding inflatable penile prostheses using a publicly available natural language processing tool (ChatGPT).

INTRODUCTION: The evolving landscape of healthcare information dissemination has been dramatically influenced by the rise of artificial intelligence (AI) driven chatbots, providing patients with accessible and interactive platforms to obtain knowledge about medical procedures and conditions. Among the various surgical interventions in urology, inflatable penile prosthesis (IPP) is a common treatment for men with erectile dysfunction. As patients increasingly seek comprehensive resources to understand what this procedure entails, AI-based chat technologies, such as ChatGPT, have become more prominent. This study aimed to assess the capacity of ChatGPT to provide accurate and easily understandable responses to common questions regarding the IPP procedure. MATERIALS AND METHODS: Ten frequently asked questions (FAQ) about the IPP procedure were presented to the ChatGPT chatbot in separate conversational sessions without follow up questions or repetitions. An evidence-based approach was employed to assess the accuracy of the chatbot's responses. Responses were categorized as "excellent response not requiring clarification," "satisfactory requiring minimal clarification," "satisfactory requiring moderate clarification," or "unsatisfactory requiring substantial clarification." RESULTS: Upon review, 70% of ChatGPT's answers to questions regarding the IPP procedure were rated as "excellent," not necessitating further clarification. Twenty percent were considered "satisfactory," requiring minimal clarification, notably on the omission of statistical data and the depth of discussion on certain topics. Ten percent of the responses were "unsatisfactory," requiring substantial clarification, including a failure to provide a definitive answer when necessary. CONCLUSIONS: This study reveals that ChatGPT has a substantial capability to produce evidence-based, understandable responses to a majority of common questions related to the IPP procedure. While there is room for improvement, ChatGPT can serve as an advantageous tool for patient education, enhancing preoperative understanding and contributing to informed decision-making during urological consultations for IPP.

Long-term results of three-part penile prosthesis implantation with Ectopic reservoir placement in the treatment of erectile dysfunction: is supramuscular tubulation a reliable method?

BACKGROUND: Penile prosthesis implantation is the last resort for refractory erectile dysfunction. Reservoir placement is one of the biggest challenges in inflatable penile prosthesis implant surgery in several cases, especially in patients with abnormal pelvic anatomy. Ectopic reservoir placement with supramuscular approach has many advantages in these cases. RESULTS: No complications were encountered except wound site infection in 2 patients which could be controlled with antibiotic treatment. EDITS scores were not statistically different between patients divided into 2-year groups according to follow-up time. Median values of EDITS scores were high in all groups, suggesting that couples had high sexual satisfaction both in the long term and in the short term. CONCLUSIONS: We recommend placement of the supramuscular tube and reservoir through the incision described, especially in patients whose pelvic anatomy has been modified by lower abdominal surgery.

RéSUMé: CONTEXTE: L'implantation d'une prothèse pénienne est le dernier recours pour les dysfonctions érectiles réfractaires. La mise en place d'un réservoir est l'un des plus grands défis de la chirurgie d'implant de prothèse pénienne gonflable dans de nombreux cas, en particulier chez les patientes présentant une anatomie pelvienne anormale. RéSULTATS: Aucune complication n'a été rencontrée, à l'exception d'une infection du site de la plaie chez 2 patients, qui a pu être contrôlée par un traitement antibiotique. Les scores du questionnaire EDITS ne furent pas statistiquement différents entre les patients classés en groupes de 2 ans en fonction du temps de suivi. Les valeurs médianes des scores du questionnaire EDITS étaient élevées dans tous les groupes, ce qui suggère que les couples avaient une satisfaction sexuelle élevée à la fois à court et à long termes. CONCLUSIONS: Nous recommandons la mise en place du tube supramusculaire et du réservoir à travers l'incision décrite, en particulier chez les patients dont l'anatomie pelvienne a été antérieurement modifiée par une chirurgie abdominale basse.
