A Comparative Study Between 2 Different Grafts Used as Patches After Plaque Incision and Inflatable Penile Prosthesis Implantation for End-Stage Peyronie's Disease

First worldwide correction of ventral Peyronie's disease utilizing rigicon inflatable penile prosthesis combined with plaque incision & grafting with collagen fleece (PICS-technique) for residual curvature

Adjunctive residual curvature correction by plaque incision and grafting with a sutureless graft during inflatable penile prosthesis (IPP) implantation in patients with Peyronie's disease (PD) is our preferred technique. The PICS Technique (Penile Implant in Combination with the Sealing Technique) uses a self-adhesive collagen fleece (TachoSil®, Corza Medical, MA, USA) to cover the defect after plaque incision. The graft does not require sutures improving operative speed and avoiding needle stick of the implant cylinders. In this article, we present the first known application worldwide of a Rigicon Infla10® X (Rigicon, Ronkonkoma, NY, USA) device to Peyronie's ventral curvature. The patient's residual curvature of 80° after implantation was corrected by PICS through an additional subcoronal incision. At the conclusion of surgery, the penis was totally straight and rigid. No intra- and postoperative complications occurred. At the early follow-up of 12 weeks postoperatively, the patient was able to inflate and deflate the device and sexual intercourse was possible. A combination of the Rigicon Infla10® X and the PICS Technique represents a safe and successful approach for residual curvature correction during IPP in patients with ventral Peyronie's curvature. The Rigicon Infla10® X device showed excellent rigidity, and controlled expansion of the X cylinders means it can be used with the PICS Technique without restrictions. Early results are promising. Long-term follow-up and more patients are needed.

Intermediate-term results of TachoSil grafting to correct residual curvature during inflatable penile prosthesis implantation in patients with Peyronie's disease

Grafting techniques may be mandatory to improve residual penile curvature during inflatable penile prosthesis (IPP) implantation in Peyronie's disease patients. We aimed to report the intermediate-term outcomes of grafting with TachoSil (Corza Health, San Diego, USA) in patients with severe erectile dysfunction and concomitant complex Peyronie's disease through a prospective cohort study. We included 25 patients that underwent the PICS (penile implant in combination with Sealing) technique from 2017 to 2020 and were evaluated 24 months after surgery. Their mean age was 61.8 ± 8.7 years. Total straightness of the penis was achieved in 21 cases, while 4 (16%) patients presented a residual penile curvature of less than 15°. The mean penile length increased significantly (15 ± 1.2 to 16.4 ± 1.6 cm, p < 0.001). No intraoperative complications occurred, while, postoperatively, two patients developed fever and three scrotal hematoma, which resolved spontaneously. At three and six weeks, as well as at 24 months after surgery, no further complications occurred, and no cases of penile glans hyposensitivity were observed. At the 24-month follow-up evaluation, the 5-item score of the International Index of Erectile Function was 23.7 ± 1.4 (range: 20.5-25) and all patients responded positively to questions 2 and 3 of the sexual encounter profile questionnaire (p < 0.001 for all outcomes compared to baseline). Accordingly, the Erectile Dysfunction Inventory of Treatment Satisfaction score improved from 45.8 ± 6 at baseline to 25.6 ± 4.6 at 24 months, p < 0.001. Grafting with TachoSil to improve residual penile curvature during IPP is a safe and effective procedure. Nevertheless, careful patient selection and counseling, surgeon's experience with the technique, and strict postoperative penile rehabilitation are the main factors for treatment success and high satisfaction rates.

Comparison of patient-reported outcomes after penile prosthesis placement in men with and without Peyronie's disease

We evaluated outcomes in patients undergoing penile prothesis (PP) implantation for erectile dysfunction (ED) and concurrent Peyronie's Disease (PD). A clinician-developed survey to assess satisfaction was sent to 354 patients who underwent PP placement from 2012-2018 by a single-surgeon. Results were compared based on the presence or absence of concurrent PD. 79 patients completed the survey (response rate 22%), including 38 patients (48%) with concurrent ED and PD (ED/PD). Mean follow-up was 31 months (standard deviation 19). 87% felt their condition was "very much" or "much" improved. There was no significant difference in patient-reported overall satisfaction with their PP or satisfaction with current penile length/girth based on the presence or absence of PD. 87% of patients with PD were satisfied with their degree of penile straightening after PP plus or minus concurrent straightening maneuvers such as modeling, plication, or incision/grafting. Sub-group analyses were performed to evaluate outcomes in those with concurrent PD/ED who required plaque incision/grafting at the time of PP placement for more severe deformity (n = 19). 47% of these patients were dissatisfied with their current penile length, compared with only 16% of those patients with PD/ED who did not require grafting (p = 0.05). In conclusion, the presence of PD alone may not impact PP satisfaction, but patients with more severe baseline deformity who require incision/grafting may be less satisfied with outcomes including penile length.

The use of collagen fleece to correct residual curvature during inflatable penile prosthesis implantation (PICS technique) in patients with complex Peyronie disease: a multicenter study

BACKGROUND

The PICS technique (penile implant in combination with the sealing) was recently described as a valuable option to correct residual curvature during inflatable penile prosthesis (IPP) implantation in patients with complex Peyronie disease (PD).

AIM

To report the surgical and functional outcomes of the PICS technique in a multicentric series of patients.

METHODS

A consecutive series of patients with complex PD who underwent PICS were recruited. Patients were from 2 European tertiary referral centers. Data regarding baseline characteristics and perioperative, postoperative, and functional outcomes were retrospectively evaluated.

OUTCOMES

Complete penile straightness, duration of operative time and hospital stay, as well as postoperative complications (including hematoma, IPP infection, and IPP mechanical failure) were recorded, whereas functional outcomes were evaluated through the administration of validated questionnaires at baseline and 12 months postoperatively: International Index of Erectile Function-5, Sexual Encounter Profile questions 2 and 3 (SEP-2 and SEP-3), and Erectile Dysfunction Inventory of Treatment Satisfaction.

RESULTS

Thirty-seven patients with a median age of 62 years (IQR, 57-70 years) were enrolled. Median preoperative curvature was 75° (IQR, 65°-77°). Median residual curvature after IPP implantation was 60° (IQR, 50°-70°). Overall, 31 patients (84%) achieved a totally straight penis. Only 6 patients (16%) experienced a residual penile curvature (<20° in all cases) after the procedure. No intraoperative complications were detected. Nine patients (24%) developed an early postoperative complication, 3 (8%) a transient fever, and 6 (16%) a genital hematoma. A single case of IPP acute infection requiring device explantation was recorded. The survey response rate was 100%. At the 12-month follow-up evaluation, the median IIEF-5 score was 23.5 (IQR, 22.2-25) with evident improvement vs the baseline value of 10 (IQR, 8-12). Accordingly, 92% of the patients responded positively to SEP-2 and SEP-3. For the Erectile Dysfunction Inventory of Treatment Satisfaction, patients recorded a median postoperative value of 25 (IQR, 21-30) 1 year after PICS.

CLINICAL IMPLICATIONS

Complex PD is an end-stage disease featured by severe penile curvature, penile shortening, and erectile dysfunction: the gold standard approach is deemed to be penile prosthesis implantation, aiming to address penile curvature and erectile dysfunction, but in a limited percentage of cases, additional maneuvers are deemed necessary to manage residual penile curvature.

STRENGTHS AND LIMITATIONS

Our study has some limitations: the retrospective nature, relatively short follow-up, and limited number of patients.

CONCLUSION

The PICS technique may represent a reliable and effective treatment option to address significant residual curvature after IPP implantation.

Use of grafting materials during penile prosthesis implantation in patients with Peyronie's disease-a systematic review

Severe Peyronie's disease (PD) and concomitant erectile dysfunction (ED) may require plaque incision/excision and grafting (PIG) as an adjunct to penile prosthesis implantation (IPP). Currently, there is no available consensus on the best graft material to use. Our aim was to systematically review graft materials used as patches following PIG + IPP. Literature search was performed in March 2021. Only original articles in English with a series of 10 or more patients were included. Overall, a total of 17 studies were included, corresponding to a cohort of 662 patients. The mean age ranged from 45 to 65 years and most patients had curvatures >45°. Average penile lengthening ranged from 1 to 3.5 cm, average residual curvatures from 0 to 20% and decreased glans sensitivity from 0 to 20%. Eighty to 100% of patients were satisfied with cosmetic and functional results. PIG + IPP with the use of various grafts offers promising results for the treatment of patients suffering from severe PD with concomitant ED. Unfortunately, the absence of high quality and comparative studies makes it difficult to establish the optimum graft. Therefore, the level of experience of the surgical team with one or more methods should guide their choice.

Penile Prosthesis Implantation Combined With Grafting Techniques in Patients With Peyronie's Disease and Erectile Dysfunction: A Systematic Review

INTRODUCTION

Penile prosthesis (PP) implantation combined with grafting techniques is indicated in patients with Peyronie's disease (PD) and erectile dysfunction (ED) nonresponsive to medical and conservative treatment that present with residual penile curvature greater than 30°, severe penile deformity or significant penile shortening.

OBJECTIVES

To address the preoperative evaluation, the surgical procedure and the functional outcomes of grafting techniques combined with PP implantation in patients with PD and concomitant ED and to provide future perspectives on the matter.

METHODS

We performed a systematic review of the literature based on the PRISMA statement (PROSPERO ID: CRD42021224517). Records were identified by searching Medline, Scopus, The Cochrane Library and Web of Science databases as well as sources of gray literature from inception to December 2020. The quality of all included records was assessed based on a modified version of the Newcastle-Ottawa Scale for cohort studies.

RESULTS

A total of 935 patients with a mean age of 59.6 ± 9.2 years from 23 studies were included in this systematic review. All studies reported excellent short- and long-term postoperative results, as well as high satisfaction rates ranging from 80 to 100%. A mean increase of 2.7 ± 1.4 cm in penile length was observed. Among different grafting materials and different types of PP, no significant differences in terms of preoperative, perioperative and postoperative functional outcomes or complications were demonstrated. Still, the operative time was shorter in studies applying the collagen fleece TachoSil.

CONCLUSIONS

PP implantation combined with grafting is a safe and highly effective surgical procedure in patients with PD and concomitant ED. All grafting materials provide similar beneficial outcomes, but TachoSil subsequently reduces the operative time and does not require suturing. Still, no definite conclusions can be drawn regarding the superiority of one grafting technique over the other, as randomized clinical trials are lacking.

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

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

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.

Management of residual penile curvature after penile prosthesis placement

Residual penile curvature is a common situation following the implantation of a penile prosthesis in patients with Peyronie's disease. Currently, there is a variety of options for the correction of residual curvature, including penile modeling, plication techniques, as well as tunical incision/excision with or without grafting. A literature search of PubMed and Medline databases was conducted from 1964 until 2020, using search terms for all articles in the English language. In this article, we provide a review of the techniques and the outcomes, according to the published literature.

Modern treatment strategies for penile prosthetics in Peyronie's disease: a contemporary clinical review

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

Penile prosthesis implant in the management of Peyronies' disease

INTRODUCTION

Penile prosthesis implantation (PPI), performed with or without adjunct straightening techniques, is one of the available surgical options in cases of Peyronie's disease (PD) with concomitant erectile dysfunction (ED). The aim of the study was to systematically identify and evaluate evidence regarding IPP in patients with PD and ED.

EVIDENCE ACQUISITION

Using Cochrane's methodological recommendations on systematic reviews, we conducted a systematic review of the literature on clinical research regarding the use of PPI, alone or in combination with any straightening maneuvers in the treatment of patients with PD and ED. The search was carried until January 2020. We included studies in English language with primary population patients with PD and ED who underwent IPP with the intent to treat the PD. All studies that were not original clinical research articles, reported insufficient data or included fewer than 5 patients were excluded from the final analysis.

EVIDENCE SYNTHESIS

In total 43 clinical articles with more than 2000 patients (N.=2143) investigating the effects of penile prosthesis implantation (PPI) for the treatment of PD with or without ED were included in the study. Depending on the severity of the penile curvature, additional penile deformities (i.e. hourglass deformity), penile length, prior operations and surgeons experience, 6 main categories of surgical techniques of PPI for penile straightening and treatment of PD were identified: PPI only, PPI with modelling of the penis, PPI with plication of the penis on the convex side of the curvature, PPI with plaque incision(s), PPI with plaque incision/excision plus grafting and PPI with grafting and penile lengthening.

CONCLUSIONS

Overall, patients with PD and ED can expect excellent outcomes with PPI against a minimal risk of side effects. No definite conclusions can be made regarding which technique is superior.

Long-term outcomes of surgery for Peyronie's disease: focus on patient satisfaction

Immediate outcomes of surgery for Peyronie's disease (PD) are fairly easy to analyze. However, it is the patient-reported long-term outcomes which eventually determine the success of PD treatment. The goal of this observational study was to evaluate patients' satisfaction with results of surgical treatment for PD at long-term follow-up. The primary outcome was the proportion of patients who were completely satisfied with their erectile function and penile appearance. We retrospectively identified 374 patients who underwent surgery for PD (median follow-up: 9.5 years) and attempted to invite them for follow-up visit; 342 patients were available for follow-up. Only 285 (83.3%) were sexually active. Among all patients, 197 (57.6%) were completely satisfied with penile appearance; among sexually active patients, 139 (40.6%) were completely satisfied with their erections. Only 101 patients (29.5%) were completely satisfied with penile appearance and erectile function. Logistic regression analysis revealed preoperative IIEF-EF score (OR = 1.668 per 1 point; 95% CI 1.469-1.894), tunica albuginea plication (OR = 5.599; 95% CI = 1.014-30.92), use of saphenous vein (OR = 8.517; 95% CI = 2.491-29.115), and cadaveric pericardium (OR = 61.388; 95% CI = 7.674-491.11) as significant predictors of satisfaction with erectile function. Severity of curvature (OR = 0.926 per 5°; 95% CI = 0.907-0.946) and tunica plication (OR = 0.117; 95% CI = 0.019-0.738) were negative predictors of satisfaction with penile appearance. Preoperative IIEF-EF (OR = 1.497 per 1 point; 95% CI = 1.322-1.694), severity of penile curvature (OR = 0.967 per 5°; 95% CI = 0.95-0.983), and use of pericardium allograft (OR = 10.728; 95% CI = 1.363-84.46) were predictors of both endpoints (satisfaction with erectile function and cosmesis). Despite excellent surgical outcomes in PD, patients' satisfaction with penile appearance and erectile function is far from absolute and depends on many patient-related and treatment-related factors.

Peyronie's disease: Contemporary evaluation and management

Peyronie's disease is a common yet poorly understood condition characterized by penile pain, curvature, sexual dysfunction and psychological bother. Peyronie's disease represents a penile wound healing disorder, and is thought to arise from exuberant scarring in response to penile trauma in genetically predisposed men. In the absence of active treatment, the majority of men experience stable or worsening symptoms, with few reporting spontaneous resolution in penile curvature or other deformity. In contrast, penile pain improves or resolves in the majority of men. Treatment options vary based on symptom severity and stability. Several oral therapies are commonly prescribed, although to date there are no strong data to support any oral agents as monotherapy for Peyronie's disease. Other options including penile traction therapy and intralesional injections result in modest improvements for many patients, particularly when used early after symptom onset. Penile straightening through approaches, such as penile plication and plaque incision or partial excision and grafting, represent the most rapid and reliable approach to correct penile curvature once the symptoms have stabilized. Side-effects vary based on the type of surgery carried out, and include penile shortening, sensation changes and erectile dysfunction in the minority of men. In patients with drug refractory erectile dysfunction and Peyronie's disease, placement of a penile prosthesis will address both issues, and is associated with high levels of patient satisfaction. The current review provides a practical approach to the modern evaluation and management of patients presenting with Peyronie's disease.

Surgical Management of Peyronie's Disease With Co-Existent Erectile Dysfunction

INTRODUCTION

Surgical intervention in Peyronie's disease (PD) should ideally be delayed until the resolution of acute inflammatory phase.

AIM

The objective of this review was to highlight the results of penile prosthesis to correct refractory erectile dysfunction (ED) in patients with PD, and the secondary procedures that may be required to correct the penile curvature.

METHODS

A systematic search on PubMed online database using Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations was done using the MeSH terms "Peyronie's disease" and "erectile dysfunction."

MAIN OUTCOME MEASURE

Success and satisfaction rates of various procedures.

RESULTS

The search yielded 324 language-specific (English and Spanish language) articles and 58 articles were retained for final review. The following variables were assessed in different studies: number of patients, types of secondary procedure to correct the curvature, satisfaction rates, and follow-up period.

CONCLUSION

The aim of the surgery in PD should be to achieve a functionally straight penis (<20 degree curvature) with good erection. Patients with refractory ED in PD are candidates for penile prosthesis. Secondary procedures, like manual modeling, plication, plaque incision, or excision grafting, may be required depending on the degree of penile curvature and penile length. In quest for the best graft, TachoSil graft seems to have gained popularity in Europe. Krishnappa P, Fernandez-Pascual E, Carballido J, et al. Surgical Management of Peyronie's Disease With Co-Existent Erectile Dysfunction. Sex Med 2019;7:361-370.

Intraoperative methods for residual curvature correction during penile prosthesis implantation in patients with Peyronie's disease and refractory erectile dysfunction

Peyronie's disease, or fibrous transformations of the tunica albuginea of the corpora cavernosa that cause penile curvature, is estimated to affect 3.2-8.9% of the male population. Treatment options for PD are based on the severity of the penile deformity and erectile function; of which surgical options include manual modeling during penile prosthesis implantation, plication, plaque incision, and grafting. Multiple approaches may be employed; each with its own advantages, limitations, and risk/benefit ratios. In this regard, we sought to review and highlight the current approaches for the management of residual curvature, optimal patient selection, and preoperative planning.

Strategies and current practices for penile lengthening in severe Peyronie's disease cases: a systematic review

Several strategies to optimize penile length in the presence of Peyronie's Disease (PD) have been described so far. In case of severe curvature and preserved erectile function, plaque incision/excision (PIG/PEG) are advisable in order to maximize penile length, despite the risk of postoperative erectile dysfunction (ED), recurrent curvature, or penile shortening. For men with PD deformities associated to a certain degree of ED several lengthening techniques associated to penile prosthesis (PPI) implantation can be considered. Because of the potential postoperative complications, the indication must be balanced between patient's risk factors and surgeon's experience. Furthermore, adjuvant surgeries, such as prepubic V-Y plasty, suspensory ligament release, suprapubic lipectomy, and ventral phalloplasty, can be performed simultaneously or in a staged fashion to maximize the outcomes. Restoration a decent penile length in the case of a severe PD represents a real challenge for reconstructive surgeons. We present a systematic review of the literature on the current practices for penile lengthening in severe PD, providing the reader with a practical overview on the existing surgical strategies and their surgical and functional outcomes.

Evolution of the surgical sealing patch TachoSil® in Peyronie's disease reconstructive surgery: technique and contemporary literature review

PURPOSE

The aim of this study is to review the current literature that reports outcomes of Peyronie's disease (PD) reconstructive surgery using the collagen fleece TachoSil^® (Baxter, CA, USA), a novel graft that has self-adhesive properties and gained popularity in recent years.

METHODS

A literature review was performed through PubMed between 2013 and 2018 regarding the use of TachoSil^® in PD penile reconstructive surgery. Keywords used for the search were: Peyronie's disease, surgical therapy, surgical outcomes, grafting techniques, graft materials, collagen fleece, surgical patch, and TachoSil.

RESULTS

Grafting procedures are indicated for men with PD and preserved erectile function. TachoSil^® is a novel graft used for defect closure after tunical incision or partial plaque excision. Long-term results of this technique are encouraging and reliable. One major advantage over other grafts is that the TachoSil^® does not require suture fixation leading to significantly decreased operative times. Another indication is residual curvature correction by plaque incision and grafting/sealing with TachoSil^® during penile prosthesis implantation in patients with PD and severe erectile dysfunction. Besides reduced operative times, the major advantage is that there is no risk of device puncture because of the self-adhesive properties of the TachoSil^®.

CONCLUSIONS

The TachoSil^® has emerged as a safe, reliable, and promising graft in PD reconstructive surgery. Until now, this graft has met the expectations as a durable and effective graft, not only for grafting techniques but also for residual curvature correction during penile prosthesis implantation. However, future research is encouraged, preferably within prospective multicenter studies.

A Comparison of Hemostatic Patches Versus Pericardium Allograft for the Treatment of Complex Peyronie's Disease With Penile Prosthesis and Plaque Incision

OBJECTIVE

To compare outcomes between hemostatic patches (HP) versus pericardium allografts (PA) for complex Peyronie's disease with erectile dysfunction managed with inflatable penile prosthesis (IPP) and plaque incision and grafting (PIG).

METHODS

We reviewed all men who underwent IPP with PIG for PD at our institution (4/2010-9/2018). PIG was performed via relaxing tunical incisions during IPP implantation following manual modeling if there was persistent curve >30^° and/or significant narrowing. Tunical defects >2 cm were grafted. PA (Coloplast, Minneapolis, MN) or HP consisting of either Evarrest, Nu-Knit (Ethicon Inc., Somerville, NJ), or TachoSil (Baxter Int., Deerfield, IL) were used.

RESULTS

HP was placed in 18 men (n = 10 Evarrest, n = 6 Nu-Knit, and n = 2 TachoSil), 15 had PA. There was no difference in mean age, preoperative curvature (HP:75° vs PA:78°), or grafted area (HP:11.9 cm² vs PA:10.9 cm²) between HP and PA cohorts. Mean operative time was shorter for HP (122 vs 166 minutes, P = .01). Median follow-up: 6.6 months (range: 2-27 months) for HP and 34.6 months (range: 13-103 months) for PA. Residual curvature >20° was present following HP in 16.7% (n = 3) and PA in 13.3% (n = 2; P = 1.0). There were no complications attributable to HP/PA material and no IPP herniation through the tunical defect. Postoperatively, 94.4% (n = 17) of HP and 93.3% (n = 14) of PA patients were engaged in penetrative intercourse (P = 1.0).

CONCLUSION

HP are effective materials to cover the tunical defect over an IPP following plaque incision for PD. HP outcomes are similar to PA, while operative time is shorter for HP.

Recent advancements in penile prosthetics

Since the original inflatable penile prosthesis in the 1970s, several enhancements to penile prosthesis implant design, implant surgical technique, and post-operative care have been developed to increase overall patient (and partner) satisfaction rates. We, in this communication, seek to discuss these advancements and the overall impact in combating erectile dysfunction. As we continue to pursue avenues of effective and definitive treatment modalities for erectile dysfunction refractory to medical therapy, rates of infection and mechanical failure will hopefully continue to decline in the perioperative setting.
