Erectile dysfunction (ED) is a disorder that can cause distress and shame for men suffering from it. Men with ED will often turn to online support and chat groups to ask intimate questions about their health. ChatGPT is an artificial intelligence (AI)-based software that has been trained to engage in conversation with human input. We sought to assess the accuracy, readability, and reproducibility of ChatGPT's responses to frequently asked questions regarding the diagnosis, management, and care of patients with ED. Questions pertaining to ED were derived from clinic encounters with patients as well as online chat forums. These were entered into the free ChatGPT version 3.5 during the month of August 2023. Questions were asked on two separate days from unique accounts and computers to prevent the software from memorizing responses linked to a specific user. A total of 35 questions were asked. Outcomes measured were accuracy using grading from board certified urologists, readability with the Gunning Fog Index, and reproducibility by comparing responses between days. For epidemiology of disease, the percentage of responses that were graded as "comprehensive" or "correct but inadequate" was 100% across both days. There was fair reproducibility and median readability of 15.9 (IQR 2.5). For treatment and prevention, the percentage of responses that were graded as "comprehensive" or "correct but inadequate" was 78.9%. There was poor reproducibility of responses with a median readability of 14.5 (IQR 4.0). Risks of treatment and counseling both had 100% of questions graded as "comprehensive" or "correct but inadequate." The readability score for risks of treatment was median 13.9 (IQR 1.1) and for counseling median 13.8 (IQR 0.5), with good reproducibility for both question domains. ChatGPT provides accurate answers to common patient questions pertaining to ED, although its understanding of treatment options is incomplete and responses are at a reading level too advanced for the average patient., Competing Interests: Competing interests The authors declare no competing interests.

Background: The increasing popularity of the silicone sleeve penile implant has been accompanied by concerns over potential risks and adverse events., Objectives: To provide multi-institutional data on safety outcomes in patients undergoing silicone sleeve penile implant surgery across high-volume implant surgeons. In addition, we discuss preventative techniques to minimize postoperative complications and the management of these events., Design and Methods: We performed a retrospective analysis of men undergoing penile silicone sleeve implants between November 2020 and November 2022 with four surgeons, each from a separate institution. Perioperative and postoperative adverse events, including unsatisfactory cosmetic outcomes requiring revision, were determined by physician follow-up. Flaccid penile length and girth were measured preoperatively and postoperatively., Results: A total of 299 male patients underwent silicone sleeve implant surgery, with an average age of 42.5 ± 10.5 years and an average body mass index of 28.5 ± 4.0. The patient cohort exhibited minimal comorbidities, with 5% having hyperlipidemia, 2% being smokers, 2% having cardiovascular disease, and 1% having diabetes. Patients experienced an average increase of 4.1 ± 1.5 cm in their flaccid penile length (a 50% increase) and an average increase of 3.4 ± 1.5 cm in their flaccid girth (a 37% increase) ( p  < 0.01). Complication rates included new-onset postoperative erectile dysfunction (0%), infection (1.3%), seroma (2.0%), and erosion (5.0%). The average follow-up time was 11.6 months. Notably, our rates of infection and seroma were lower than those reported in a previous single-center review, while erosion rates were higher., Conclusion: This is the largest study to characterize the safety of the penile silicone sleeve implant across multiple institutions. In men who desire cosmetic size augmentation, silicone sleeve implant surgery is associated with significantly increased flaccid penile length and girth. Complications are mainly cosmetic and may be corrected; however, patients should be appropriately counseled on the risk of erosion, which appears to be higher than previously reported., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2024.)

Erectile dysfunction is a major postoperative complication following radical prostatectomy. Various treatments for post- radical prostatectomy erectile dysfunction including nonsurgical phosphodiesterase-5 inhibitors, intraurethral alprostadil, intracavernosal injections and penile implant prosthesis, often yield suboptimal results. In this prospective single-center case series, we examine the efficacy and outcomes of Himplant ® , a subcutaneous silicone penile implant, placement in four patients with post-radical prostatectomy erectile dysfunction who experienced limited benefits with phosphodiesterase-5 inhibitors. Patient data including demographics, prostate cancer diagnoses, erectile dysfunction characteristics, previous treatments, and outcomes were collected. Himplant ® placement was performed in a standardized manner through a high scrotal incision in all cases. Follow-up evaluations were conducted to assess the effectiveness of the procedure and any associated complications. Patients were contacted and asked 15 questions regarding satisfaction and erectile function with the responses recorded. This study presents findings of high patient satisfaction, increases in flaccid penile length and girth, no incidence of adverse events, and improved erectile function following Himplant ® placement post-radical prostatectomy. Accordingly, we suggest Himplant ® placement in patients who are frustrated by their penile appearance and suffering from erectile dysfunction after radical prostatectomy. Further multicenter studies are warranted to validate these findings and assess long-term outcomes and patient-reported satisfaction., (© 2024. The Author(s).)

Objective: Since the advent of the Mulcahy technique of three-piece inflatable penile prosthesis (IPP) salvage, there have been multiple iterations of salvage prosthesis procedures reported in the literature. All of these techniques employ traditional antibiotic irrigation with or without rechanneling. We present our technique of salvage IPP using 0.05% chlorhexidine gluconate (Irrisept ® ) with corporal rechanneling for length preservation., Materials and Methods: Our technique of IPP salvage begins with access via a 5 cm vertical midline scrotal incision. Dissection down to the corpora is performed with a combination of blunt dissection and dissection with fine tipped Metzenbaum scissors. Each component of the prior IPP is sequentially removed starting with the cylinders, followed by the pump, and finally the reservoir. Irrisept ® is used to copiously irrigate out both cavernosal bodies as well as the scrotal compartment and prior reservoir location. A two minute dwell time of the Irrisept ® is employed after mechanical irrigation. A penrose drain is placed from the space of Retzius through a separate stab incision in the scrotum. Corporotomies are closed, followed by Dartos fascia and scrotal skin. A complete change in gown and gloves of all members of the surgical team and a new set of drapes and instruments is performed. Through a separate subcoronal incision, two new corporotomies are made and separate channels created using nine inch Metzenbaum scissors. These channels are irrigated with Irrisept ® . A 9 mm malleable penile prosthesis (MPP) is inserted and corporotomies and skin incision are closed., Results: A total of four men with prior penoscrotal IPP placement underwent salvage IPP with MPP from January 2022 to October 2022. Median operative time was 165 minutes. Median preoperative cylinder size was 23.5 cm. Median postoperative malleable cylinder size was 23 cm. Median length of follow up was 4.8 months. There were no cases of MPP erosion or infection. Two patients elected to undergo repeat IPP insertion after 6 months with same cylinder size., Conclusion: IPP salvage with chlorhexidine irrigation and soak as well as separate corporal channeling in a noninfected field for MPP insertion is a viable strategy for infected prostheses given the ease of performance, low risk of repeat infection of the malleable device, and maintenance of corporal length of any subsequent prostheses., Competing Interests: None., (AJCEU Copyright © 2023.)

Objective: To provide new data, techniques, and safety and efficacy outcomes in patients undergoing Penuma penile implant surgery at a large tertiary care center., Methods: We performed a retrospective analysis of men undergoing Penuma implants between November 2020 and January 2022 with a single surgeon at a tertiary hospital. Measurements of penile length were made both pre- and postoperatively. Adverse events including infection and unsatisfactory cosmetic outcomes requiring revision were recorded. We also provide detailed technique descriptions of Penuma implantation and revision. Outcomes include measurements of incidents of peri and post-operative adverse events and penile length and girth pre- and post-operatively., Results: 49 male patients underwent Penuma implant surgery. Mean age was 40.2 ± 8.9 years. Mean BMI was 28.2 ± 4.5. All but 2 patients were nonsmokers and only 2 had comorbidities (diabetes). Preoperative mean flaccid length was 8.1 ± 1.9 cm. Postoperative mean length was 12.3 ± 1.9 cm. Patients added an average of 4.9 ± 2.9 cm to their penile length, a 52% increase (P < .01). Average follow up time was 6 months. Among the complications were 1 case of infection and 2 cases of erosion. There were 4 cases of persistent flaring of the Penuma; 3 required revision surgery, all with a good cosmetic outcome., Conclusion: The Penuma implant can be used to safely enhance flaccid penile length and girth in patients with retractile penis or other cosmetic deformities. Should complications occur, they are mainly cosmetic and can be easily corrected with low risk., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Introduction: Previous worked showed that the Andrianne Mini-Jupette (AMJ) procedure with inflatable penile prosthesis (IPP) significantly improves climacturia or stress urinary incontinence (SUI) that may accompany erectile dysfunction (ED) after radical prostatectomy. However, with the AMJ procedure, the graft is incorporated into the medial aspect of the corporotomy, thereby requiring a more complex closure. Moreover, in the original report, multiple graft materials were used., Aim: To describe our technique for "male urethral mini-sling" (MUMS) with a Virtue sling mesh, which is a modified approach to the AMJ, and to assess early postoperative outcomes., Methods: A retrospective chart review was performed for men who underwent IPP and MUMS placement with a modified Virtue mesh by 2 high-volume prosthetic urologic surgeons using the same technique. After proximal urethral exposure, the MUMS is sutured to the latera corpora over the bulbar urethra, proximal to and separate from the planned corporotomy, with care taken to avoid excessive urethral tension. The IPP is then placed in standard fashion. Changes in patient-reported climacturia and pads per day for SUI were assessed before and after surgery., Results: 36 men underwent both IPP and MUMS placement between January 2016-October 2018. Mean patient age was 68 years. Etiology for ED and urinary symptoms was prostatectomy alone in 30 of 36 (83%) and prostatectomy plus radiation in 6 of 36 (17%). Preoperative urinary symptoms included climacturia in 30 of 36 (83%) and SUI in 27 of 36 (75%). Mean (SD) follow-up was 5.9 (3.7) months. Climacturia resolved in 28 of 30 (93%), and SUI improved in 23 of 27 (85%). The mean (SD) number of pads per day for those patients with SUI decreased significantly from 1.4 (1.1) before surgery to 0.4 (0.6) after surgery (P = .02). 1 patient required MUMS explantation for urethral erosion after prolonged postoperative catheterization., Clinical Implications: The MUMS with modified Virtue mesh at the time of IPP placement can be used to treat ED with climacturia or mild SUI after radical prostatectomy., Strengths & Limitations: Strengths include the use of a consistent operative technique with a single graft material by 2 experienced prosthetic urologic surgeons. Limitations include the retrospective study design, use of subjective postoperative outcomes, lack of comparison group, and relatively moderate follow-up duration., Conclusions: Our early results suggest that the MUMS significantly improves bothersome climacturia and mild SUI in addition to treating ED, with little added morbidity. Although further study, including longer-term follow-up, is needed, this approach may be considered in the appropriately counseled patient. Valenzuela RJ, Ziegelmann MJ, Hillelsohn JH, et al.

Introduction: Penile prosthetic devices are the gold standard treatment of medication-refractory erectile dysfunction. Inflatable penile prosthetic (IPP) devices have been available and used for more than four decades. Oftentimes, medical conditions causing erectile dysfunction also cause penile shortening, causing decreased patient quality of life., Aim: To identify and review all available penile lengthening procedures that can be performed at time of IPP insertion., Methods: An extensive, systematic literature review was performed using PubMed searching for key terms penile lengthening, inflatable penile prosthesis, penile girth, corporoplasty, glans augmentation, and penile enhancement; all articles with subjective and/or objective penile length outcomes were reviewed., Main Outcome Measures: A review of various techniques for penile length and girth preservation and enhancement during penile prosthesis insertion., Results: Several advanced and novel techniques were found for penile length preservation and enhancement at time of IPP insertion, including the sub-coronal IPP insertion technique, and adjuvant maneuvers during insertion, such as the sliding technique, modified sliding technique, multiple slice technique, and circumferential incision and grafting. Other adjuvant techniques that can enhance perception of increased length include ventral phalloplasty, suprapubic lipectomy, and suspensory ligament release. Further enhancement can be obtained using augmentation corporoplasty and glans augmentation with hyaluronic acid and other fillers. The different techniques vary in complexity and could require specialized training and experience. Maximum length gain appears to be limited by the length of the neurovascular bundles., Conclusion: Overall, surgical penile lengthening procedures at time of IPP insertion appear safe and effective for treatment of patients with penile shortening and severe erectile dysfunction. These therapies can significantly improve patient self-esteem and quality of life in properly selected patients. Tran H, Goldfarb R, Ackerman A, Valenxuela RJ.

Loss of penile length is a common complaint of men with Peyronie's disease (PD), both before and after corrective intervention, which has a significant negative effect on patient quality of life. We sought to identify and describe the methods by which penile length can be preserved or increased. We conducted an extensive, systematic literature review, based on a search of the PUBMED database for articles published between 1990 and 2015. Articles with the key words "Peyronie's disease", "penile length" and/or "penile lengthening" were reviewed if they contained subjective or objective penile length outcomes. Only English-language articles that were related to PD and penile size were included. We found no evidence in the literature that medical therapy alone increases penile length. Classic inflatable penile prosthesis (IPP) placement, plication procedures, and the Nesbit procedure appear likely to maintain or decrease penile length. Plaque incision (PI) and grafting appears likely to maintain or increase penile length, but is complicated by risk of post-operative erectile dysfunction (ED). There are several surgical procedures performed concomitantly with IPP placement that may be suitable treatment options for men with comorbid ED, and consistently increase penile length with otherwise good outcomes concerning sexual function. These include the subcoronal penile prosthesis (scIPP), Egydio circumferential technique, the sliding technique, the modified sliding technique (MoST), and the multiple slice technique (MuST). In addition, adjuvant therapies such as penile traction therapy (PTT), post-operative inflation protocols, suspensory ligament relaxation, lipectomy, and adjuvant medical therapy for glans engorgement appear to increase subjective and/or objective penile length for men at high risk of decreased penile length after PD surgery. Considering the psychological burden of length loss in men with PD, providers with adequate volume and expertise should attempt, if possible, to maintain or increase penile length for men undergoing surgical intervention. There are several evidence-based, safe, and effective ways to increase penile length for these men and multiple emerging adjuvant therapies that may help ensure adequate length.

The objective of this study was to anatomically describe the relationship of penile intracavernosal pillars to penile surgery, specifically corporal dilation during penile prosthesis placement. Corpora cavernosa from four embalmed male cadavers were dissected and subjected to probe dilation. Corpora were cross-sectioned and examined for the gross presence and location of pillars and dilated spaces. Infrapubic penile prosthesis insertion was performed on one fresh-frozen cadaveric male pelvis, followed by cross-sectioning. A single patient had intracavernosal pillars examined intraoperatively during Peyronie's plaque excision and penile prosthesis insertion. Intracavernosal pillars were identified in all cadavers and one surgical patient, passing obliquely from the dorsolateral tunica albuginea across the sinusoidal space to the ventral intercorporal septum. This delineated each corpus into two potential compartments for dilation: dorsomedial and ventrolateral. Dorsal dilation seated instruments and prosthetics satisfactorily in the dorsal mid glans and provided additional tissue coverage over weak ventral areas of the tunica albuginea, while ventrolateral dilation appeared to result in ventral seating and susceptibility to perforation. Intracavernosal pillars are an important anatomic consideration during penile prosthesis placement. Dorsal dilation appears to result in improved distal seating of cylinder tips, which may be protective against tip malposition, perforation or subsequent erosion.

Introduction: The surgical treatment of disorders of male sexual function requires specific exposure to correct the underlying problem safely and efficiently. Currently, sub-coronal exposure is used for treatment of phimosis, Peyronie's disease plaque (PDP), and semirigid penile prosthesis insertion. Infra-pubic and scrotal incisions are used for inflatable penile prosthesis (IPP) placement. However, men who present with several disorders might require multiple procedures and surgical incisions., Aim: To report a prospective review of our surgical experience and outcomes with a single sub-coronal incision for IPP placement with a modified no-touch technique. This approach allows for access to the entire corporal body for multiple reconstructive procedures., Methods: Two hundred men had IPPs placed through a sub-coronal incision using our modified no-touch technique. The penis was degloved to the level of the penoscrotal junction and the dartos muscle was everted and secured to the drapes. This allowed exclusion of the scrotal and penile skin from the operative field. After artificial erection, the patient's corpora were inspected for PDP and other abnormalities. Penoscrotal IPP models were placed in all cases with insertion proximal to the penoscrotal junction. After placement of the IPP, the abnormalities were repaired., Main Outcome Measures: Feasibility of the procedure, operative times, complication rate, utilization of accessory, reconstructive procedures, and post-operative penile length., Results: Of the 200 men who had IPP placement, 92 had PDP that was treated, 106 (53%) consented to circumcision, 24 (12%) had their reservoir placed ectopically, and 31 (16%) had a prosthesis exchanged through the sub-coronal technique. Mean operative time was 73 minutes (39-161 minutes)., Conclusion: Specialists in the surgical treatment of disorders of male sexual function can perform multiple procedures safely and easily through a modified no-touch single sub-coronal incision. This approach allows access to the entire corporal body, providing excellent visibility and allowing the surgeon to perform multiple penile reconstructive surgeries through a single incision., (Copyright © 2016 International Society for Sexual Medicine.
