(PM-17) THE ROLE OF PHOSPHODIESTERASE-5 INHIBITORS IN THE TREATMENT OF COMPLEX PENILE WOUNDS: A CASE REPORT AND LITERATURE REVIEW

Abstract Introduction/Objective Phosphodiesterase-5 inhibitors (PDE5i) are traditionally employed for the management of erectile dysfunction and lower urinary tract symptoms. However, their role in the healing of complex penile wounds remains scarcely discussed. This study aims to describe the case of a 27-year-old man who suffered from penile strangulation, treated with sildenafil. Additionally, a literature review concerning the use of PDE5i for the treatment of complex penile injuries will be conducted. Methods A 27-year-old man presented to the emergency room after a self-induced penile strangulation using a ring placed at the base of the penis. Extensive necrosis of the corpus cavernosum was identified through magnetic resonance imaging. Considering the psychosocial implications of penile amputation, organ preservation was chosen, and conservative treatment with sildenafil and daily local dressings was initiated. Thirty days after admission, Doppler ultrasound revealed symmetrical corpus cavernosum with normal echogenicity and usual blood flow patterns. Subsequently, the patient underwent superficial necrotic tissue debridement followed by partial skin grafting in a second stage, leading to hospital discharge after 55 days of hospitalization. Results PDE5 inhibitors enhance nitric oxide bioavailability, promoting vasodilation and improved tissue oxygenation, thereby facilitating various phases of the healing process. Evidence indicates their benefit in microvascular perfusion in skin and soft tissues. Reports suggest satisfactory outcomes of topical PDE5i application in radiation-induced lesions, implying their role in epidermal cell expansion, reduction of inflammatory infiltrates, enhanced vascularization, and decreased collagen deposition. Conclusion This study presents a successful case of sildenafil use in treatment of a complex penile wound, shedding light on an unconventional application of PDE5i. Financing No conflict.

(101) Exploring Intraoperative and Postoperative Penile Prosthetic Complications in the Solid Organ Transplant Population: A Propensity-Score Matched Analysis

Abstract Introduction Solid-organ transplant (SOT) patients are highly susceptible to adverse post-operative outcomes given they are on one or multiple immunosuppressant medications. This makes surgeons performing elective surgeries, such as penile prosthetic implant surgery, understandably concerned given the higher risk of potential infection and perioperative complications. However, data regarding the safety and efficacy related to the penile prosthesis in the SOT population is mixed. Our study aimed to analyze adverse intraoperative and post-operative complications related to the penile prosthesis using the TriNetX database. Objective To observe whether SOT patients experienced more intraoperative and postoperative penile prosthetic complications when compared to the general population using the TriNetX US Collaborative Network, a large real-world database consisting of deidentified patient data from 56 healthcare organizations across the United States. Methods We used the TriNetX database to perform a propensity score-matched cohort study comparing five-year outcomes between SOT patients (kidney, heart, lung, liver, pancreas, and intestine by ICD-10) who underwent either an inflatable or non-inflatable penile prosthetic procedure (SOT) and non-SOT patients who underwent a similar procedure(s) (non-SOT). Patients were excluded from the analysis if they had any instance of priapism (treatment or dx) or Peyronie disease (treatment or diagnosis) in their medical record prior to the penile prosthetic procedure. Cohorts were matched on age, race/ethnicity, CKD, diseases of the prostate or prostatectomy, overweight and obesity status, T2DM, cardiovascular disease, psychiatric disorders, substance-use disorders, and spinal cord injury. Outcomes of interest included intraoperative and perioperative complications as well as post-operative complications related to the prosthetic implant (mechanical malfunction, fibrosis, displacement, hemorrhage, pain, stenosis, removal with or without replacement, and complex [all post-operative complications]). Results There were 223 patients in each group after matching (SOT, non-SOT). Mean age at penile prosthesis procedure 60.4 ± 10.2, 52% were White, and 8.9% were Hispanic/Latino. Kaplan-Meier analysis revealed that there was no significant difference found for the incidences of intraoperative complications (0.49% vs 0.53%, p = 0.99). In regards to postoperative complications, we found significantly higher incidences of complex prosthetic complications (28.76% vs 18.28%, p = 0.01) and mechanical malfunction of the penile prosthesis (8.56% vs 3.45%, p = 0.03) in the SOT cohort when compared to the non-SOT cohort. No significant difference was found between the cohorts for 5-year incidences of fibrosis (p = 0.81), hemorrhage (p = 0.97), pain (p = 0.69), stenosis (p = 0.81), infection (p =0.34), displacement (p = 0.68), removal with replacement (p = 0.72), and removal without replacement (p = 0.91). Conclusions In our analysis of this large, real-world database, we found that SOT patients were more likely to experience complex penile prosthetic complications as well as mechanical malfunction of the penile prosthesis. However, we observed no difference in 5-yr incidences of stenosis, fibrosis, hemorrhage, pain, infection, displacement, and prosthesis removal between the cohorts. Our analysis reveals that surgeons performing penile prosthetic surgeries, should be aware of potential long-term mechanical malfunction complications related to the penile prosthesis in the SOT population.

(196) Advanced Surgical Management for the Ramifications of Neglected Penile Fracture with Pericardial Graft Reinforcement

Abstract Introduction Penile fractures occur when the tunica albuginea, a fibrous layer surrounding the corpora cavernosa, ruptures during sexual intercourse or masturbation. These incidents, although rare, are considered serious emergencies. Failure to address them promptly can result in complications such as erectile dysfunction, penile curvature, and hematoma. Unfortunately, cases often go unreported due to embarrassment or fear, resulting in delayed medical attention. Diagnosing penile fractures is mainly clinical, and treatment options depend on the timing of presentation. Objective To emphasize the importance of early medical attention and surgical intervention in the context of penile fractures, with the goal of preventing or reducing the occurrence of long-term complications. Methods A 55-year-old male developed a query penile fracture during intercourse. Initially, he experienced a popping sound with no visible signs of injury nor loss of erection. Two weeks later, he sought medical advice due a penile bump development accompanied by painful erections. Conservative management was provided with ice, non-steroidal anti-inflammatory drugs, and sexual abstinence. However, he later presented with a penile mass and curvature affecting his penetration during intercourse. A penile Doppler ultrasound revealed a fibrotic hematoma with a complex cystic lesion measuring 23.1 mm x 18.1 mm x 28.3 mm. The patient underwent a complex penile mass excision, tunica albuginea plication with pericardium graft reinforcement. The surgery involved excising scar tissue, removing the underlying fibrotic hematoma and cystic lesion, correcting the curvature, and reinforcing the weakened tunica albuginea with pericardium graft (Tutoplast, IOP Ophthalmics, Costa Mesa, CA, USA) (Figures 1–3). Histopathology reported grossly “a penile fibrotic mass with irregular dark brown firm cystic structure filled with yellow-tan necrotic tissue”. Microscopic description showed “a fibrous capsule with central hemorrhage and fibrin”. Results The patient had a successful procedure & uneventful smooth recovery. During 6 & 12 months follow-up, there was no long-term complications, he reported resolved curvature and satisfactory sexual intercourse Surgical treatment is recommended for penile fractures to achieve satisfactory results and restore sexual function. Various graft materials can be used to reinforce penile defects. Tutoplast (processed allograft tissue from cadaveric pericardium) has shown excellent results in Peyronie's curvature repair. The efficacy of bovine pericardium compared to Tutoplast in urologic surgeries is uncertain. In this particular case, Tutoplast was chosen due to its accessibility and the surgeons expertise in Peyronie's repair and penile prosthesis implantation. Conclusions This case report highlights the formation of a fibrotic hematoma resulting from delayed penile fracture presentation, which was managed through mass excision & correction of curvature. To date, there is no literature mentioning fibrotic hematoma formation as a consequence of neglected fracture presentation. Prompt medical attention with low threshold for early surgical intervention should be sought for suspected penile fractures to avoid potential long-term complications and improving their quality of life.

Management of the anatomically complex penile implant candidate through an infrapubic incision: a review of surgical techniques and benefits.

This article provides a comprehensive discussion of 3-piece inflatable penile implant surgery when performed through an infrapubic approach in patients presenting with challenging anatomy or corporal fibrosis. The infrapubic approach is one of the primary approaches for inflatable device placement with excellent long-term functional outcomes. While the literature is rich in descriptions of infrapubic placement in the primary, uncomplicated setting, its role in the management of complex patients presenting to centers of excellence is less elucidated. In uncomplicated cases, the infrapubic approach offers several theoretical advantages including shorter operative time and quicker return to sexual function. In addition to describing specific details of our infrapubic technique and perioperative management, I discuss scenarios in which an infrapubic approach may allow for better exposure for correction of dorsal deformity, facilitate secondary surgical maneuvers such as suprapubic lipectomy, or protect existing incontinence prosthetics already in place. Specific technique and surgical pearls from our prosthetic center of excellence are reviewed for each of these challenging scenarios. Ultimately, prosthetic surgeons should be adept at placing, revising, and removing devices through both approaches so that various forms of anatomical deformity and device failures can be addressed proficiently. In addition to my own clinical reflections, a critical review was performed using the Medline database to support our statements.

Circular Penile Skin Fasciocutaneous Ventral Onlay Flap Urethroplasty as an Alternative to Dorsal Onlay Buccal Mucosal Graft Urethroplasty in Complex Long-Segment Urethral Stricture: A Retrospective Study.

Background A urethral stricture is the narrowing of the urethra that results in symptoms of obstruction. It can appear anywhere along the male urethra's length and has a variety of causes.The circular penile fasciocutaneous flap is employed in the successful single-stage reconstruction of long-segment complex anterior urethral strictures especially when the buccal mucosa is unavailable due to various reasons.The study has tried to identify a surgical technique that is more beneficial for the treatment of urethral strictures. Objective The objective of this research was to evaluate the outcomes of circular penile skin fasciocutaneous ventral onlay flap urethroplasty (group A) and the outcomes of dorsal onlay buccal mucosal graft urethroplasty (group B) in the management of complex long-segment penile urethral stricture. Methods In this retrospective study between December 2012 and December 2022, 60 patients with long-segment complex penile urethral stricture who underwent urethroplasty at our center were evaluated. Patients were divided into two groups according to the flap used (dorsal onlay buccal mucosal graft urethroplasty was used in 30 patients (group B), and circularpenile fasciocutaneous flap (single stage) was used in 30 patients (group A)). The success rate and the mean peak flow rate were also calculated post-operation to identify the effectiveness of the surgical procedure used for urethral strictures. Results The study consisted of 60 patients in total. Group A's mean age was determined to be 51.2±16.2 years, whereas group B's mean age was determined to be 40.7±16.8 years. Preoperatively, the median urethral stricture length was 69 mm in group A (range: 20-100 mm) and 56 mm in group B (range: 30-110 mm). The intraoperative median length of the urethral stricture was 82 mm in group A (range: 20-120 mm) and 65 mm in group B (range: 40-140 mm). The mean peak flow rate was 30.9±6.8mL/s in group A compared to 18.1±4.9mL/s in group B. The success ratefor group A was 89.7%, while the success rate forgroup Bwas 75.9%. Conclusion For complexlong-segment urethral strictures, circular penile skin fasciocutaneous ventral onlay flap urethroplasty has a higher rate of success and fewer complications than dorsal onlay buccal mucosal graft urethroplasty. Along with success rate, it has a better mean peak flow rate and lower complications.

(198) How to Use VSI HoloMedicine for Beginners: Imaging and Surgical Instrument’s Sharing

Abstract Introduction Extended Reality-Assisted Surgery (XRAS) is a novel technology that superimposes a computer-generated image in the physicians’ visual field to integrate common elements of the surgical process in advanced detail. Although XRAS has already been utilized by several medical disciplines, many face challenges with implementation and perceive integration between the hardware and software for XRAS to be quite burdensome. Nevertheless, the present group has successfully reported XRAS in complex penile implant revision surgery. In order to help reduce the learning curve, we present this introductory video demonstrating how users may sign into the software for XRAS, download patient imaging, demonstrate imaging to other doctors, and employ surgical tools “live” with other colleagues. Objective Video for beginners to XRAS to learn how to sign onto VSI HoloMedicine®, download patient imaging, demonstrate the imaging to other doctors and usage of surgical tools and penile implants ‘live” with other surgeons. Methods The hardware utilized for XRAS was XR Microsoft HoloLens (Microsoft, Redmond, WA, USA) while VSI HoloMedicine (XX, Dusseldorf, Germany) was the software program. Raw data from CT scans were downloaded onto VSI HoloMedicine. Local Wi-FI was used for connecting different surgeons remotely to discuss patient care decision-making and surgical tool usage. Results Signing onto VSI HoloMedicine and downloading patient imaging is detailed. Two (2) de-identified patient’s imaging was shown to surgeon colleagues for discussion and clinical assistance in making patient care decisions. Surgical tool and penile implant components were demonstrated while connected to another surgeon. Conclusions With proper instructions as shown on this video, getting on and connecting with other surgeons through XRAS can be straightforward. Here, we demonstrate how to download patient imaging, show the imaging details in-depth and how surgical tools and penile implants can be successfully implemented during XRAS.

Complex penile fracture after straddle injury: A case report

Introduction: Penile fracture due to staddle injury is an underreported surgical emergency. Fall down in perinium can present with not only scrotum/perinium hematoma but can associated with more complicated injuries such as pelvis fracture, complex penile fracture with urethral injury, corpus cavernosal and spogiosium raptures. These findings lead to worse morbidity in the patient, especially in terms of sexual life and urinary symptoms. If such severe injuries are not properly managed, erectile dysfunction and urethral stricture can happen, leading to more complicated problems. Case Report: A 23-year-old male presented to the emergency department with complaints of scrotal swelling and pain for three hours due to fall from height on perinium. He had classic signs of a urethral injury and penile fracture. Conclusion: Penile fracture is not always spared injury and does not always occur during erection, but is sometimes associated with other injuries and in flaccid phase.

Patients with Peyronie’s disease achieve complete plaque regression after multimodal treatment with antioxidants: a case series

BackgroundPeyronie’s disease is a chronic inflammatory condition of the corpora cavernosa characterized by the formation of plaque in the tunica albuginea, which results in penile deformity. Conservative medical approaches encompass oral, topical, and physical treatment. Only two cases of patients with Peyronie’s disease with complete plaque regression after treatment have been described in literature.Case presentationCase 1: A 50-year-old Caucasian man with penile pain and double penile curvature of 5° (left ventrolateral), palpable nodule, and normal penile rigidity. The patient underwent multimodal therapy (oral antioxidants + topical diclofenac gel). At follow-up after over 4 years of treatment, the patient no longer complained of any penile deformity or pain. Ultrasound examination did not show any plaque. Case 2: A 26-year-old Caucasian man with lateral-right penile curvature of 30° (previous congenital curvature of 15°), palpable nodule, and normal penile rigidity. The patient underwent multimodal therapy (oral antioxidants + topical diclofenac gel + penile injections/pentoxifylline). After 28 months of treatment, the patient presented a lateral right curve of 15° at follow-up, similar to the original congenital penile curvature. Ultrasound examination no longer showed any plaque. Case 3: A 36-year-old Caucasian man with penile pain and a complex penile curvature of 15° and 20° (left dorsolateral), palpable nodule, and normal penile rigidity. The patient underwent multimodal therapy (oral antioxidants + topical diclofenac gel + penile injections/pentoxifylline). At follow-up after 28 months of treatment, the patient presented a dorsal curve (10°) similar to the original congenital curvature. Penile palpation did not detect any nodules, and ultrasound no longer showed any plaque.ConclusionsThis study demonstrates that our multimodal therapy is able to completely regress plaque, as demonstrated in our previously published article. Peyronie’s disease has the potential to be treated conservatively with good results. However, this method of treatment needs to be combined with accurate ultrasound assessment, performed using a sufficiently advanced machine by an experienced operator.

An original mininvasive corporoplasty technique for penile curvature without circumcision

We describe an original minimally invasive penile plication technique with scrotal or infrapubic access, not requiring circumcision, for penile curvature of different severity and types. This technique can be used to correct both congenital and acquired curvatures, mono or bidirectional deformities. Between 2012 and 2018 we treated 134 patients suffering from congenital curvature (33) and acquired curvature from Peyronie's disease (101). The average curvature was 62.2° (± 30.4°). Preoperative evaluation included prostaglandin E1 injection with photographic documentation and measurement of penile angulation, administration of IIEF- 15, vasoactive penile Doppler ultrasound, analysis of thermal and vibratory sensitivity with Genito-Sensory-Analyzer (GSA) and assessment of nocturnal penile stiffness with Rigiscan, performed twice, for a detailed evaluation of patient's erectile function. Scrotal access was performed in patients with dorsal and/or lateral penile curvature; the infrapubic access was performed in patients with ventral curvature. After preparation and incision of Colles' fascia, penis was partially degloved and an original plication technique called "binary corporoplasty" was performed at the site or sites established at preoperative assessment, with non-resorbable synthetic multifilament (Premicron®) suture. Complete correction of penile curvature was achieved in 96.8 % of patients. No major complications were reported, and no patients suffered worsening in erectile function or in penile sensitivity. The average shortening of convex side was 1.65 cm (± 0.7 cm) and all patients report easy intercourse after correction. The average time of surgery was 46 minutes (± 11 min) and all procedures were performed as a day-hospital or ambulatory settings, with local anesthesia and light sedation. Overall satisfaction rate is 96%. This is a simple and rapid technique that perfectly corrects even the most severe and complex penile curvatures. In comparison to traditional techniques, such as Nesbit procedure, this technique is associated with low morbidity, a very low recurrence rate and a great aesthetic results. Aesthetic and functional patients' satisfaction was excellent.

Extended Reality-Assisted Surgery as a Surgical Training Tool: Pilot Study Presenting First HoloLens-Assisted Complex Penile Revision Surgery

Extended reality-assisted urologic surgery (XRAS) is a novel technology that superimposes a computer-generated image on the physician's field to integrate common elements of the surgical process in more advanced detail. An extended reality (XR) interface is generated using optical head-mounted display (OHMD) devices. To present the first case of HoloLens-assisted complex penile revision surgery. We describe our pilot study of HoloLens-assisted penile revision surgery and present a thorough review of the literature regarding XRAS technology and innovative OHMD devices. The ability of XRAS technology to superimpose a computer-generated image of the patient and integrate common elements of the surgical planning process with long-distance experts. XRAS is a feasible technology for application in complex penile surgical planning processes. XRAS and OHMD devices are novel technologies applicable to urological surgical training and planning. Evidence suggests that the potential use of OHMD devices is safe and beneficial for surgeons. We intend to pioneer HoloLens technology in the surgical planning process of a malfunctioning penile implant due to herniation of the cylinder. This novel technology has not been used in prosthetic surgery, and current data about XRAS are limited. OHMD devices are effective in the operative setting. Herein, we successfully demonstrated the integration of Microsoft HoloLens 2 into a penile surgical planning process for the first time. Further development and studies for this technology are necessary to better characterize the XRAS as a training and surgical planning tool. Quesada-Olarte J, Carrion RE, Fernandez-Crespo R, et al.

Penile Fracture with Urethral Rupture

Penile fracture with an associated urethral injury is a rare urological emergency resulting from trauma to the erect penis during vigorous sexual intercourse. The patient often presents with swelling of the penis, discoloration of the penile skin, localized pain, and hematuria with a typical history of sudden detumescence during intercourse. Subcoronal penile degloving incision has been conventionally described and is frequently used by many clinicians for the management of penile fracture-urethral injury. Here, we describe a case of complex penile fracture managed through the vertical penoscrotal incision. The penoscrotal approach confers excellent exposure to both the ruptured corpus cavernosum and urethra. This approach ensures successful outcomes in such an emergency procedure without having disadvantages of the degloving incision.

Auxetic Expansion of the Tunica Albuginea for Penile Length and Girth Restoration Without a Graft: A Translational Study.

IntroductionSeveral conditions can cause penile length and girth loss. Surgical techniques have been used to restore these penile alterations in patients with severe erectile dysfunction during penile prosthesis implantation. One technique uses multiple small incisions in a mesh pattern (similar to a skin mesh) with satisfactory curvature correction without using a graft, however, this technique does not allow simultaneous increase in penile length and girth.AimTo identify a new surgical technique that increases both the length and girth at the same place on the corpora cavernosa (CC), allowing a simultaneously longitudinal and transverse increase of the tunica albuginea.MethodsA sheet with a star-shaped perforation was created using a mathematical model to allow a longitudinal and transversal increase in the material. Two previously published penile model simulators, with and without deformity, were used to test the mechanical modification of this incision pattern in the CC.Main Outcome MeasureThe effect of the incisions pattern on the geometry of the CC simulator.ResultsThe star-shaped incision (auxetic) simultaneously increased the length, girth, and volume of the CC simulator. This auxetic technique could correct any penile deformity, re-establishing the original penile anatomy. The new auxetic incision is only a conceptual and experimental technique awaiting clinical evidence.ConclusionThe data presented here show that the auxetic technique successfully increases both the length and girth at the same place on the CC simulators, opening a new potential solution to correct challenging cases of complex penile deformities and to restore volume loss.Miranda A, Auxetic Expansion of the Tunica Albuginea for Penile Length and Girth Restoration Without a Graft: A Translational Study.

Vascularized composite allotransplantation of the penis: current status and future perspectives.

Given the multifunctional role of the penis in daily life, penile loss can be a physically and emotionally devastating injury. Options to restore penile loss have traditionally relied on autogenous free flap, local flaps, and skin grafts. These techniques provide satisfactory outcomes but carry high rates of urologic and prosthesis-related complications. Vascularized composite allotransplantation may offer a novel solution for these patients through reconstruction with true penile tissue. Still, penile transplants pose ethical, logistical, and psychosocial challenges. These obstacles are made more complex by the limited cases detailed in published literature. A review of the literature was conducted to assay current practices for penile reconstruction. Most modern complex penile reconstructions utilize autogenous pedicled or free tissue flaps, which may be harvested from a variety of donor sites. A total of five penile transplants have been described in the literature. Of these, four report satisfactory outcomes. The advent of genital allotransplantation has recently broadened the landscape of treatment for penile loss. Reconstruction using true penile tissue through vascularized penile allotransplantation has the possibility to engender increased penile function, sensation, and overall quality of life.

Management of Disastrous Complications of Penile Implant Surgery

Penile Prosthesis Implantation (PPI) is the definitive treatment for Erectile Dysfunction not responsive to conservative management strategies. Furthermore, it is a staple of surgical treatment of severe Peyronie's Disease (PD) and phallic reconstruction. Expert implantologists occasionally face disastrous complications of penile implant surgery which can prove to be very challenging. In this article we present a selected number of case reports which exemplify this kind of situations and discuss management strategies while also commenting on plausible aetiologies. The first case describes a PPI performed in end-stage fibrotic corpora after multiple instances of implantation/explant. The second and third cases show two diametrically opposed approaches to the management of glans necrosis after PPI in post-radical cystectomy patients. The fourth case describes the history of a diabetic patient suffering from glandular, corporal and urethral necrosis after a complicated PPI procedure. The fifth case reports the surgical treatment of a case of recurring PD due to severe scarring and shrinking of a vascular Dacron patch applied in a previous operation. Complication diagnosis in all patient was mainly clinical, intra- and postoperative, with Penile Color Doppler Ultrasonography performed when needed in order to demonstrate penile blood flow. The patients underwent complex surgical procedures that addressed each specific complication. Complex penile implants with fibrosis-related complications, penile prosthesis explant with and without surgical debridement of necrotic areas, penile prosthesis explant with necrotic penile shaft and urethral amputation with perineostomy, and complex corporoplasty with scar tissue excision and patch application with PPI were performed in the five patients. Penile anatomy and erectile function with PPI was achieved in 4 out of 5 patients. 1 of 5 patient is scheduled to undergo a total phallic reconstruction procedure at the time of this writing. Management of disastrous complications of penile implant surgery can be very challenging even in expert hands. In-and-out knowledge of possible PPI and PD complications is required to achieve an acceptable outcome. Bettocchi C, Osmonov D, van Renterghem K, etal.

Children undergoing outpatient complex penile surgery and hypospadias repair may not require opioid analgesics

Background/PurposePain control is important after penile surgery, and opioid use should be minimized as able. We sought to describe our experience performing complex penile surgeries with vs without post-operative opioids. MethodsA retrospective review of penile surgeries, including 3998 between 2009 and 2019. We identified patients <8 years who underwent outpatient penile surgery requiring either penile degloving or hypospadias repair. Patients who were or were not prescribed opioids were matched 1:1 by age and type of penile surgery. Primary outcomes of interest were pain-related encounters, delayed opioid prescription, and predictors of pain. Results200 children were identified, 100 per group, with mean age 1.3 ± 0.8 years. 48% were penile degloving procedures, 31% hypospadias repairs with catheters, and the remaining 21% hypospadias repairs without catheters. Perioperative features were comparable between groups(p > 0.05). 59% of patients without opioids had an impromptu post-operative encounter vs 41%, and 20% had an associated pain complaint vs 9%(p = 0.026). Two patients in both groups received delayed opioid prescription(p = 1.00). The presence of a catheter (OR 2.9) and no opioid prescription (OR 2.6) were independent predictors for pain complaint. ConclusionsPatients discharged without an opioid were more likely to contact a provider postoperatively and were more likely to endorse pain complaint (number needed to treat: 9).

Buccal mucosa graft in surgical management of Peyronie's disease: Ultrasound features and clinical outcomes.

Plaque incision and grafting represent the best surgical approach to the Peyronie's Disease (PD). The grafting procedures must be restricted to patients with normal preoperative status, excessive curvature and/or deformities. However, the ideal graft has not been identified yet. Buccal mucosa grafts (BMG) provided excellent short-term results, ensuring the fast return of spontaneous erections and preventing shrinkage, which is the main cause of graft failure. Another fearsome surgical complication is de novo erectile dysfunction (ED). We report our results with BMG focusing on the analysis of ultrasonographic and clinical data demonstrating buccal mucosa as determinant factor that allow to avoid complications. From 2013 to 2019 we performed at our Urology Unit 27 corporoplasties with BMG to correct complex penile curvature due to PD. Clinical, post-surgical and ultrasound follow up data were evaluated. All patients were no responders to medical treatment or previous surgical procedures. The evaluation period was 72 months. Data regarding pre-operative work-up, including IIEF (IIEF-5) questionnaire administration, detailed clinical history and penile dynamic ultrasound (PGE1-induced erection) were collected. The time of spontaneous erection resumption was recorded for each patient. To improve blood supply to the graft, a low-dose PDE5-i was prescribed for all patients for a period of two months, starting immediately after discharge. Check-ups were scheduled every 3 months, starting from 1 month after surgery. In each visit, patients underwent a penile ultrasound evaluation of graft features. After 6 and 12 months, all patients underwent a penile dynamic ultrasound for Erection Hardness Score determination, then standard ultrasound and clinical evaluation yearly. Our analyses were focused on BMG as a major determinant of the surgical success. Mean age of 27 patients was 57 years (42-71) with a maximum follow up time of 72 months and minimum of 3. Site of penile curvature was dorsal in 18 (67%) patients, ventral in 2 (7%), complex in 7 (26%). The degree of the curvature was < 60° in 11 (41%) patients, > 60° in 16 (59%). Straightening of penis was reached in 100% of cases. Penile shortening resulted in 7.4% (2/27). De novo ED appeared in 2/27 cases with a post-operative rate of PDE5i users increasing from 12 to 14 patients (45% vs 52%). Ultrasound aspects of BMG, recorded at every follow up visit, results in a hypoechoic plaque with an iperechoic rim that become isoechoic over the time in all cases. No case of scars or seroma was registered. Small intra-graft cystic lesions were highlighted in 3 cases (11%). BMG may represent a good choice in grafts procedures for PD surgical management. The functional results obtained by BMG procedures were related to the good anatomical characteristics of the patch and were highlighted in our series by use of penile ultrasound, during the follow up period.

The use of collagen fleece (TachoSil) as grafting material in the surgical treatment of Peyronie's disease. A comprehensive narrative review.

Grafting for the treatment of Peyronie's disease (PD) can be performed with autologous grafts, allografts, xenografts and synthetic grafts, with all available materials presenting their own characteristics. Still, there is a current arising interest in the use of collagen fleece (TachoSil) as grafting material. We generated an extensive literature review, aiming to assess the use of TachoSil in the treatment of PD. TachoSil is currently indicated in men with PD and preserved erectile function for defect closure after partial plaque excision or incision. In addition, it is indicated for residual curvature correction during penile prosthesis implantation (PPI) in patients with PD and severe erectile dysfunction. Our literature search identified 12 studies evaluating the role of TachoSil for PD surgical treatment. We presented the surgical procedure of TachoSil grafting for the treatment of complex penile curvatures with or without simultaneous PPI and summarized the available evidence on the matter. Identified studies suggest that TachoSil is considered highly effective, reliable and safe in patients with PD. Moreover, it displays favorable properties compared to other grafting materials. It should be stressed that, despite some limitations of available data, TachoSil presents key strengths, which include easy application, decreased operative times, no risk of damaging the implant during PPI, preservation or increase in penile length, fewer cases of penile hypoesthesia, low risk of other adverse events, additional hemostatic effects and low cost. Still, randomized trials comparing TachoSil with different grafting materials are necessary to establish its efficacy.
