Surgical outcomes and patient satisfaction after dermal, pericardial, and small intestinal submucosal grafting for Peyronie's disease

Grafts in Peyronie's surgery without the use of prostheses: a systematic review and meta-analysis

Peyronie's disease (PD) is characterized by abnormal penile curvature, and various surgical methods have been developed using different graft materials. However, there is currently no universal agreement on which type of graft is the best. The objective of this review was to evaluate the available literature and identify the most effective graft material for penile curvature correction in PD. A literature search was conducted using electronic databases, including PubMed, Scopus, and the Cochrane Library. The patients, intervention, comparison, and outcome (PICO) approach was used to define the eligibility of studies. Two authors independently selected studies, evaluated them, and extracted data. Random-effect models using the DerSimonian-Laird method were used. Most studies were single-arm studies and had a high risk of bias. Buccal mucosa grafts (BMG) were found to result in the highest penile straightening rates and were associated with the least de novo erectile dysfunction. TachoSil grafts demonstrated a high success rate in straightening despite a higher mean preoperative curvature, while Tutoplast grafts had a higher incidence of postoperative erectile dysfunction. BMG had the highest percentage of postoperative penile straightening. Overall, the TachoSil graft showed the best performance when preoperative curvature is taken into account. Based on the available literature, BMG appear to be the most effective for penile curvature correction in PD, but this is offset by the requirement for low preoperative curvature. The TachoSil graft shows the best overall performance when preoperative curvature is considered. Comparative randomized clinical trials are still needed to determine graft superiority.

Comparison of technical success and adverse events of plaque incision and grafting methods in patients with Peyronie's disease: Tunica vaginalis versus buccal mucosa

OBJECTIVE

To compare the clinical outcomes of Peyronie's disease (PD) patients who were treated by plaque incision and grafting either with tunica vaginalis (TV) or buccal mucosa (BM) grafts.

METHODS

PD patients in BM (n=20) and TV group (n=20) were recruited between 2013 and 2020. Erectile dysfunction was assessed by short form of International Index of Erectile Function Questionnaire (IIEF-5). Technical success was defined as residual curvature ≤15°. Penile Doppler ultrasound was performed at baseline evaluation, 3-, and 24 months. Peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistance index were measured in erect penis. Erect penile length and curvature angle were measured at baseline and at 3, 12, and 24 months.

RESULTS

Mean age of the groups was comparable (47.2±10.8 years in TV vs 46.5±9.9 years in BM groups). Baseline mean penile curvature was 48.0±6.6° (TV) and 50.3±11.6° (BM) (p<0.001). Mean residual curvature at 24-months visits was 12.4±4.9° (TV) and 7.9±3.7° (BM), not significantly different. Technical success rate was 90% for both groups at 24 months. Surgery significantly increased erect penile length in both groups. Mean preoperative IIEF-5 scores were 18.4±2.5 and 17.5±2.2 in TV and BM groups, respectively. In both groups, IIEF-5 scores significantly improved after surgery with no intergroup IIEF-5 difference (20.6±2.6 in TV and 21.3±2.2 in BM). Mean postoperative PSV significantly increased, EDV significantly decreased in both groups, however, there was no significant intergroup difference.

CONCLUSION

Both grafting materials provided similar beneficial effects regarding technical success, erectile dysfunction, and penile length.

Clinical Significance of Shortened Penile Length and Alterations in Penile Length Following Treatment for Peyronie's Disease

INTRODUCTION

Across many cultures, penis size has been associated with virility, and concerns about penile length are commonplace. Peyronie's disease (PD) is a known acquired cause of penile shortening.

OBJECTIVES

This paper describes the psychosocial impacts of penile length on men and their partners, both generally and in men with PD, and evaluates the effect of PD treatments (eg, collagenase clostridium histolyticum , surgery, mechanical therapy) on this outcome measure.

METHODS

A PubMed database search was performed for English language articles through July 2021. Main outcome measures were association of penile length with emotional well-being, selfesteem, and relationship satisfaction in men with PD, and change from baseline penile length after treatment.

RESULTS

Shortened penile length caused by PD can negatively impact patient and partner quality of life, including effects on body image, emotional well-being, sexual function, and interpersonal relationships. In men with PD, studies have demonstrated an association between loss of penile length and emotional problems, reduced satisfaction with sexual performance, poor self-esteem, depression, and relationship difficulties. Loss of penile length can frequently occur after surgery for PD (including plication, plaque incision/excision with grafting, and penile implant). Advanced surgical techniques may preserve/increase penile length, but the increased risks associated with these complex procedures must be carefully considered. Treatment with collagenase clostridium histolyticum does not appear to negatively impact penile length, and 5-year follow-up data suggest potential longterm posttreatment improvements in this outcome measure. Penile traction therapy, either alone or as adjunctive therapy, may increase penile length in men with PD, but nonadherence may limit improvement.

CONCLUSION

Changes in penile length are important to many men, particularly those with PD, and should be considered during PD treatment selection. Penile length should be measured objectively before and after treatment for PD and should be included as an outcome measure in future studies on treatment effectiveness.

ESSM Position Statement on Surgical Treatment of Peyronie's Disease

INTRODUCTION

Patients with Peyronie's disease may experience significat distress. The choice of treatment depends on a variety of factors, including the stage of the disease, the presence of pain, severity and direction of the curvature, penile length and the quality of erectile function.

AIM

To review the evidence associated with surgical treatment of Peyronie`s Disease and provide clinical recommendations on behalf of the European Society for Sexual Medicine. 131 peer-reviewed studies and systematic reviews, which were published from 2009 to 2019 in the English language, were included.

METHODS

MEDLINE, Google Scholar and EMBASE were searched for randomized clinical trials, meta-analyses, open-label prospective and retrospective studies.

MAIN OUTCOME MEASURE

The panel provided statements on clinically relevant questions including patient involvement in the decision process, indications for surgery, choice of the approach, and the management of patient expectations. A comparison of the different grafts used in patients who have undergone plaque incision/excision and grafting in order to identify an ideal graft, has been carried out. The prevalence of postoperative complications has been summarized. Levels of evidence were provided according to the Oxford 2011 criteria and Oxford Centre for Evidence-Based Medicine recommendations.

RESULTS

In order to allow shared decision making, a patient preoperative counselling regarding the pros and cons of each intervention is recommended. In particular, adverse effects of surgical treatments should be discussed to set realistic understanding and expectations of surgical outcomes and ultimately improve postoperative satisfaction rates. Surgical treatment should be only offered in the chronic phase of the condition, when the deformity and/or degree of erectile dysfunction, prevent patients from engaging in satisfying sexual interaction, or if the deformity is the cause of severe bother.

CONCLUSIONS

Current European Society for Sexual Medicine recommendations cover several aspects of Peyronie's disease treatment. These recommendations aim both to ensure patients and partners have accurate and realistic expectations of their treatment options, as well as to formulate algorithms to guide clinician management pathways.

A decade of grafting techniques as a sole treatment for Peyronie's disease

BACKGROUND

Peyronie's disease (PD) can be a cosmetically and functionally devastating condition. Surgical approaches have been proposed in the chronic stages of PD as plication or plaque incision/excision with grafting to preserve penile size in complex cases. Although several surgeons nowadays are inclined toward the utilization of non-autologous grafts owing to the ease of their preparation and availability, synthetic graft procedures still await more technical improvements and supporting evidence before their consideration for standard care.

OBJECTIVES

In this review, our goal is to facilitate an insight into the most promising grafting materials used for the management of PD and techniques associated.

MATERIALS AND METHODS

A PubMed review was conducted for all the studies on our topic within the past ten years (January 2009 until December 2019). The outcome parameters we documented and compared comprised of operative time, follow-up time, postoperative penile cosmesis and function, and, finally, overall patient satisfaction related to each technique.

RESULTS

Our search yielded 23 English-written original study articles in addition to a single case report on the various grafting techniques utilized as the sole treatment for PD, each demonstrating different outcomes and points of comparison.

CONCLUSION

A successful grafting procedure for PD requires an appropriately tailored surgical modality and an experienced surgeon. Nevertheless, proper preoperative patient counseling on all aspects of his condition and opted treatment modality while setting clear and realistic expectations remains key for overall patient satisfaction.

Negative Self-Perception and Self-Attitude of Sexuality Is a Risk Factor for Patient Dissatisfaction Following Penile Surgery with Small Intestinal Submucosa Grafting for the Treatment of Severe Peyronie's Disease

OBJECTIVE

To assess patient satisfaction with surgical outcome, body related self-perceptions, self-attitudes of sexuality, and health related quality of life after penile surgery with small intestinal submucosa (SIS) grafting for the treatment of severe Peyronie's disease (PD).

MATERIAL AND METHODS

This retrospective study included 82 patients, who were treated with SIS grafting for severe PD between 2009 and 2013 at the University Medical Center Hamburg-Eppendorf. Patients were asked to complete standardized questionnaires including the International Index of Erectile Function Erectile Function domain (IIEF-EF), Short-Form (SF)-8 Health Survey, and Frankfurt Body Concept Scale-Sexuality (FKKS-SEX).

RESULTS

Follow-up was available in 58 (69.9%) patients. SIS grafting resulted in subjective straightening of the penis in 53 (91.3%) patients. After a mean follow-up of 28.9 ± 16.5 months, 24 (41.4%) patients were satisfied or very satisfied with surgical outcome. Postoperatively, the mean FKKS-SEX was 23.5 ± 5.9. In total, 36 (62.1%), 18 (31%), and four (6.9%) patients had FKKS-SEX scores corresponding to positive, neutral, and negative self-perception and self-attitude of sexuality, respectively. The mean postoperative SF-8 was 15.2 ± 6.4. Compared to the mean for German controls, patients achieved lower mean scores in the domains social functioning (50.4 ± 7.1), mental health (49.5 ± 9.2), and emotional roles (48.5 ± 6.8). Subjective shortening of the penis (Odds ratio (OR): 2.0), negative body related self-perceptions, and self-attitudes of sexuality (OR: 3.6) as well as IIEF-EF score (OR: 0.9) were risk factors for patient dissatisfaction (p-values ≤ 0.02).

CONCLUSION

A relevant number of patients is not satisfied with surgical outcome after SIS grafting for the treatment of severe PD. Subjective shortening of the penis, negative body related self-perceptions, and self-attitudes of sexuality as well as IIEF-EF score were risk factors for patient dissatisfaction.

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.

The comparison of an acellular matrix graft with an autologous venous graft in the surgical treatment of Peyronie's disease

The aim of this study was to evaluate acellular porcine pericardium (APP) and compared the results with those obtained from venous grafts in the surgical management of Peyronie's disease (PD). An APP (Group 1) and an autologous saphenous vein graft (Group 2) were used in 27 and 26 patients, respectively for Peyronie's correction. The patients' age, body mass index (BMI), operation time, duration of follow-up, preoperative and postoperative IIEF-5 scores, plaque size and loss of sensation were evaluated in both groups. There were no differences between the two groups in terms of age, BMI, follow-up period, and preoperative and postoperative IIEF-5 scores. The postoperative IIEF-5 scores were higher than the preoperative IIEF-5 scores in both groups. The operation time was significantly longer in Group 2 than in Group 1. The duration of sensation loss was shorter in Group 1 compared to Group 2. Penile shortening was similar in both groups.

Penile Sensory Changes After Plaque Incision and Grafting Surgery for Peyronie's Disease

INTRODUCTION

Plaque incision and grafting (PIG) for Peyronie's disease (PD) is not devoid of complications such as erectile dysfunction and penile sensory changes.

AIM

To define the rate and chronology of penile sensation loss after PIG surgery and to define predictors of such.

METHODS

The study population consisted of patients with PD-associated penile curvature who underwent PIG surgery with at least 6 months of follow-up. Demographics and PD factors were recorded. Patient had preoperative assessment of penile sensation and deformity. Postoperative follow-up occurred at 1 week, 1 month, 6 months, and 1 year after surgery. Neurovascular bundle elevation was conducted with loupe magnification.

MAIN OUTCOME MEASURE

Penile sensation was evaluated with a biothesiometer and graded on a patient-reported visual analog scale (0-10) in which 0 defined a completely numb area and 10 defined perfect sensation. The degree of sensation loss was defined as extensive (any 1 area >5 cm), major (2-5 cm), and minor (≤2 cm). The penile sensation loss distribution was defined as focal (1 site) or diffuse (>1 site).

RESULTS

63 patients were analyzed. Mean age was 56 ± 10 years. Mean duration of PD at the time of PIG was 15 ± 7 (12-38) months. 75% had curvature alone, and 25% had hourglass/indentation deformities. Mean primary curvature was 64˚ ± 28˚. The mean operation duration was 3.5 ± 1.8 hours. 21% had some degree of sensation loss at 1 week, 21% at 1 month, 8% at 6 months, and 3% at 12 months. Only 1 patient (1.5%) at 2 years continued to have extensive sensation loss on the glans and distal shaft with a very elevated sensitivity threshold. Using multivariable analysis, the only predictor of penile sensation loss ≥6 months was a duration of operation >4 hours (odds ratio = 2.1; 95% confidence interval = 1.2-3.0; P < .01).

CLINICAL IMPLICATIONS

The study highlights the need during patient consent to discuss penile sensation loss. Patients should be informed that rates of penile sensation loss ranges from 2-30% and most patients will have complete resolution of any sensation loss within one year of follow-up.

STRENGTH AND LIMITATIONS

To our knowledge no other studies have described the chronology and severity of penile sensation following PIG, our study demonstrates the utility of biothesiometry in measuring penile sensation before and after PIG. Number of patients and absence of control group represent a limitation.

CONCLUSION

Sensation loss is not uncommon after PIG surgery. It decreases in frequency and severity with time with only rare cases occurring >12 months. Longer operations appeared to be more likely associated with sensation loss. Terrier JE, Tal R, Nelson CJ. Penile sensory changes after plaque incision and grafting surgery for Peyronie's disease.

Penile Reconstructive Surgery in Peyronie Disease: Challenges in Restoring Normal Penis Size, Shape, and Function

To provide an overview of current approaches to penile reconstructive surgery in Peyronie disease (PD), and to discuss the challenges in restoring normal penile size and function. A systematic literature search was conducted to identify the published literature relevant to PD and penile reconstructive surgery. A summary of the published guidelines from major organisations is included in this review paper. Penile plication is simple and minimally invasive, and tends to preserve potency in most patients. However, plication invariably results in penile length loss and may, in fact, worsen the existing hour-glass or hinge effect. In contrast, graft reconstructive surgery can address issues relating to the loss of penile length and complex penile deformities, but long-term data highlight the risks of altered glans sensation, recurrent curvature, and/or loss of penile length from graft contracture, as well as the development of erectile dysfunction. Complex penile reconstruction with the concurrent placement of a penile prosthesis and/or graft material is a demanding operation that should be performed by surgeons with extensive prosthetic and reconstructive experience, as the risk of sensory loss, glans ischemia/necrosis, prosthesis-related complications, and failure to gain any meaningful length are serious concerns and cannot be underestimated. While surgical approaches remain the standard of care, they pose considerable risks and require prolonged postoperative rehabilitation. Obtaining proper informed consent and establishing realistic outcome expectations are imperative for successful postoperative outcomes.

The extra-tunical grafting procedure for Peyronie's disease hourglass and indent deformities

Background

To describe a novel, tunica-sparing surgical technique—extra-tunical grafting (ETG)—for the treatment of penile indent and hourglass (HG) deformities and to describe patient-reported outcomes after the ETG procedure.

Methods

An IRB-approved, retrospective chart review of ETG patients was performed to collect data including pre-operative deformity, operation performed, and post-operative patient-reported perception of deformity, erectile function, penile sensation, and overall satisfaction with the ETG operation. The indications for surgery were difficulty with sexual intercourse due to deformity and/or poor cosmesis of the penis. Pre-operatively all patients had erections adequate for intercourse with or without medications. The ETG procedure is performed through a ventral longitudinal penile skin incision. The dissection is continued to the level between Dartos and Bucks fascia, circumferentially for HG deformity and focally for indent deformity. The neurovascular bundle (NVB) is left undisturbed. A cadaveric fascia graft is applied, singly or in multiple layers, to fill the exposed tunical depressions. Our preferred graft material is Tutoplast Suspend^® (Coloplast, Minneapolis, MN, USA). The graft is sutured into position with multiple interrupted, long-lasting absorbable sutures to achieve the desired penile shaft contour. The urethra is excluded from the graft.

Results

From October 2013 to June 2017, 36 patients had the ETG procedure for HG and/or indent with or without penile curvature. Results with a minimum of 6 months of follow-up could be extracted for 18 of the patients. One was excluded as he required concurrent excision of a large calcified tunical plaque, which necessitated incision into the tunica albuginea (TA). Follow-up was between 6 and 44 months (average 21 months). All patients reported satisfactory resolution of the HG or indent. No patient reported worsened erectile function. Two patients (11.8%) reported slight penile hypoesthesia, with one of these having had multiple previous penile degloving surgeries for trauma. Ten of the patients reported being “very satisfied” and six reported being “satisfied” with the procedure. One was neutral. All reported that they would recommend the ETG procedure to a friend, and all would repeat the same surgery again.

Conclusions

The ETG procedure is a straightforward approach to HG and indent deformities to correct the penile deformity and to provide structural support to prevent penile buckling during intercourse. The procedure does not violate the TA and does not require dissection of the NVB. Thus, ETG carries a very low risk of de novo impotence or hypoesthesia as highlighted by this patient series. With such low risk and high patient-reported satisfaction rates, the ETG procedure is a valuable surgical technique for the treatment of complex penile deformities.

2018 Canadian Urological Association guideline for Peyronie's disease and congenital penile curvature

Peyronie’s disease (PD) is a highly prevalent condition that affects the physical and psychosocial well-being and quality of life (QoL) for thousands of Canadian men. The specific etiology of PD remains poorly understood and there remains a paucity of randomized placebo-controlled trials evaluating treatment interventions.1-3 PD can be found in up to 8.9% of men, a remarkable increase in cited prevalence that is attributable to growing awareness (as historical data suggested a rate of less than 1%); the burden of disease is significant, and PD is often present in otherwise healthy men. The following guidelines were crafted by the committee with a full awareness of the limitations of the literature, and sought to provide actionable recommendations to guide PD care in the Canadian health system.

Use of a lyophilized bovine pericardium graft to repair tunical defect in patients with Peyronie's disease: experience in a clinical setting

Many different materials are available for grafting during surgery for Peyronie's disease (PD). To study the outcomes associated with the use of a lyophilized bovine pericardium graft (Peri-Guard®) to repair tunical defects in patients with PD, descriptive study of 43 patients with disabling penile curvature was performed. Curvature was measured before and after the intervention using a standardized procedure. Surgical technique was plaque excision and grafting of the tunical defect carried out by a single surgeon. A lyophilized bovine pericardium patch was used for grafting. We measured the change in penile curvature and length, the ability to perform successful sexual intercourse without further pharmacological or surgical treatment, and the satisfaction with treatment. Follow-up data were available for a total of 41 patients. Median age was 50 years (IQR 48-52); mean follow-up time was 14 ± 6 months. Complete penile straightening was achieved in 33 patients (80.5%) and five patients (12.2%) had curvature under 20°. Three months after surgery and stretching therapy, mean (s.d.) flaccid penile length increased from 11.2 ± 2.8 cm to 12.1 ± 2.9 cm (P = 0.062). Seventy-five percentage of patients reported being able to achieve successful intercourse without further treatment. Eighty-five percentage of patients reported to be satisfied with the treatment. There was no evidence of tissue rejection or infection, and only four patients suffered an adverse event. Plaque excision and grafting of the tunical defect with lyophilized bovine pericardium seems to be a safe and effective treatment for patients with PD.

Satisfaction of patients with Peyronie's disease after plaque surgery and bovine pericardium graft

INTRODUCTION

Plaque and bovine pericardium graft surgery is a useful tool for treating Peyronie's disease.

OBJECTIVE

To determine patient satisfaction following this operation.

MATERIALS AND METHODS

This was a retrospective, observational and descriptive study. We collected data from the medical records of patients who underwent surgery between 2004 and 2015 and were evaluated through a postoperative satisfaction questionnaire.

RESULTS

Twenty-eight operations were performed. Curve correction was achieved in 26 patients (95.3%). One patient (3.57%) required residual curve correction using Yachia's technique, and 1 patient (3.57%) had a severe complication consisting of prosthetic infection and urethrocutaneous fistulae. Twenty-one patients (75%) expressed satisfaction with the surgery.

CONCLUSIONS

Our results show an acceptable level of satisfaction among our patients, with a low number of complications. However, further prospective, controlled and randomised studies are needed.

Bicentric prospective evaluation of corporoplasty with porcine small intestinal submucosa (SIS) in patients with severe Peyronie's disease

INTRODUCTION

Advanced Peyronie's disease (PD) with severe penile deviation demands grafting procedures following plaque incision or partial plaque excision in order to avoid penile shortening and to improve quality of life of affected patients. Small intestinal submucosa (SIS) is an established xenograft. The objective of the present study was to validate external results in a bicentric prospective manner.

METHODS

Patient selection criteria, surgical technique and standards for pre- and postoperative care were defined. Consecutively, patients with severe penile deviation in stable disease and sufficient erectile function were included between 2007 and 2015. After plaque incision, grafting was performed using SIS in a standardized manner. The postoperative evaluation using a non-validated questionnaire included complications, correction of curvature, pre- and postoperative erectile function, change in penile length and general satisfaction with the procedure.

RESULTS

Forty-three patients underwent surgery between 2007 and 2015. The mean degree of preoperative curvature was 73.8° (range 60-90°). No intraoperative or major postoperative complications were reported. After a mean follow-up of 33.0 months (range 10-59), complete straightening of the penis was achieved in 74.4%. 88.4% of all patients were able to achieve satisfying sexual intercourse (67.4% unaided, 21.0% with assistance). The IIEF-5 score was improved in 69.8% (mean improvement 4.0 points). Overall 86.0% were satisfied with the surgical treatment.

CONCLUSION

Corporoplasty with SIS in patients with PD and severe penile curvature is a safe approach and shows good long-term results. A thorough patient selection and a standardized pre-, intra- and postoperative procedure are decisive for a satisfying outcome.

Grafting techniques for Peyronie's disease

Peyronie’s disease (PD) is a benign fibrotic condition of the penile tunica albuginea. PD can be associated with penile pain, curvature, shortening, and erectile dysfunction (ED). The predominant and most bothersome symptom in affected patients is penile curvature, which can lead to inability to have sexual intercourse. In such cases, surgical correction of the curvature may be required. Plication techniques to correct curvature can cause penile shortening and therefore are generally reserved for curvatures <60°. Penile prosthesis implantation with simultaneous correction of curvature by various means is recommended in PD patients with ED not responding to medical therapy. Grafting techniques are the preferred surgical treatment in patients with penile curvatures >60°, short penis, or hourglass deformity. Patients scheduled for grafting surgery are required to have satisfactory erectile rigidity preoperatively. There are various grafting materials that can be used for closure of the tunica albuginea defect following plaque incision/excision. Both autologous and non-autologous grafts have been used for PD reconstructive surgery, and each graft has its advantages and disadvantages. Novel grafting materials are presented and discussed in this review. A major advantage of the available “off-the-shelf” grafts is that there is no harvesting from a donor site and, thus, morbidity is reduced, and operative times are minimized. Further investigations in regard to tissue-engineered grafts to improve surgical handling and postoperative outcomes are ongoing. Surgeon experience, careful patient selection, patient preference and type of penile deformity affect the choice of graft. This review summarizes the literature within the past 5 years regarding grafting techniques in PD. Surgical outcomes and limitations of grafting techniques are reported. A major objective of this review is dedicated to preoperative considerations and indications for grafting procedures, with the aim to improve surgical outcomes and increase patient satisfaction. Proper postoperative management of patients after incision/excision and grafting is important to avoid early and long-term complications and unwanted outcomes. This review provides an overview of recent advances and recommendations in regard to rehabilitation strategies after grafting procedures. Adequate preoperative patient counseling, careful patient selection, appropriate indications, and postoperative management is key to optimal surgical outcomes with high satisfaction rates after grafting techniques in PD surgery.

A review of the epidemiology and treatment of Peyronie's disease

Introduction

Peyronie’s disease (PD) has significant effect on patients and their partners. We provide a current review of the epidemiology as well as the nonsurgical and surgical treatment of PD.

Materials and methods

Review of literature pertaining to PD with focus on epidemiology and treatment options.

Conclusion

PD is common and likely underreported. The availability of new and highly effective treatment options will catalyze patient awareness and subsequently the prevalence of disease.

Do adult men with untreated ventral penile curvature have adverse outcomes?

INTRODUCTION

Congenital ventral penile curvature without hypospadias is often treated surgically in childhood. The history of untreated ventral curvature is unknown.

OBJECTIVE

This study's aim was to examine the association of untreated ventral penile curvature with various sexual and psychosexual outcomes.

STUDY DESIGN

An electronic survey was advertised to men older than 18 years on Facebook. Men with possible ventral penile curvature identified themselves by choosing sketches that most closely represented their anatomy. Outcomes assessed included: Sexual Health Inventory for Men, difficulty of intercourse because of curvature, International Prostate Symptom Score, Penile Perception Score, psychosexual milestones, paternity, infertility, sitting to urinate, and the CDC HRQOL-4 module.

RESULTS

Among participants, 81 out of 684 men (11.8%) reported untreated ventral penile curvature. Participants with self-reported curvature noted more difficulty with intercourse because of curvature (4.5 vs 4.9, p < 0.001), more unhealthy mental days (8.6 vs 6.2, p = 0.02), and increased dissatisfaction with penile self-perception compared with men without reported curvature (8.6 vs 9.5, p < 0.001).

DISCUSSION

Men with possible untreated ventral curvature reported worse penile perception scores, more mentally unhealthy days, and increased difficulty with intercourse secondary to curvature compared with men without curvature. A limitation to this study is selection bias; responses collected were self-reported from survey volunteers. Additionally, the question identifying ventral penile curvature is not validated but performed well in pretesting. Most questions were from validated surveys, but some were modeled after validated surveys and/or contained high face validity types of questions.

CONCLUSION

Men with possible untreated ventral penile curvature reported more dissatisfaction with penile appearance, increased difficulty with intercourse, and more unhealthy mental days. Given high success rates, low complications, and improved outcomes after surgical correction of penile curvature reported in the literature, our results support correction of congenital penile curvature in childhood.

Long-Term Results of Reconstructive Surgery for Peyronie's Disease

INTRODUCTION

Peyronie's disease (PD) is an acquired benign connective tissue disorder that involves the tunica albuginea of the penis and can cause penile deformity and shortening. Because this condition is frequently associated with cardiovascular risk factors, a degree of erectile dysfunction is frequently present. The surgical management of PD should be offered once the acute phase of the disease has settled and the deformity is stable.

AIM

To critically review the most recent literature published on the surgical management of PD.

METHODS

A nonstructured PubMed-based review of the literature published in the last 10 years, searching for the words "Peyronie's disease," "erectile dysfunction," "plication," "grafting," "plaque," and "penile prosthesis," has been carried out.

MAIN OUTCOME MEASURE

The outcome of the various surgical procedures is reported.

RESULTS

Surgery represents at present the gold standard treatment for PD. The type of procedure should be decided according to the degree of deformity, the quality of the erection, and penile length.

CONCLUSIONS

Surgery still represents the gold standard treatment in patients with PD and aims at obtaining a penis straight, rigid, and long enough for penetrative sexual intercourse. Adequate preoperative patient's selection, counselling and the choice of the right type of procedure according to the degree of penile shortening, the type of deformity and the quality of the erection are paramount to achieving satisfactory results.

Surgical management of Peyronie's disease

Peyronie's disease (PD) has a significant impact on the quality of life of both patients and their partners due to the compromised sexual function and physical deformation resulting from the condition. PD is a connective tissue disorder marked by fibrotic healing of the tunica albuginea, leading to penile deformities including curvature, shortening, loss of girth, hourglass appearance, and hinging. Despite the multiple medical therapies available, surgery is the gold standard of treatment once the plaque has stabilized. We present a review of the disease process, preoperative evaluation, operative planning, surgical treatments with outcomes and complications, and nascent developments in surgical management and graft development. Options include tunical lengthening procedures, tunical shortening procedures, and penile prosthesis. Decision-making is governed by degree of curvature, erectile function, and associated penile deformities. In cases with curvature of less than 60-70 degrees, adequate penile length, and no hourglass deformity, patients are candidates for tunical shortening procedures. Patients with curvature greater than 60-70 degrees, penile hourglass or hinge-destabilizing deformities, and adequate erectile function should be counseled with regard to tunical lengthening procedures. Patients with poor preoperative erectile function should undergo inflatable penile prosthesis placement, with possible secondary straightening procedures. Technique selection should be based upon surgeon preference, expertise, and experience, as evidence does not necessarily support one procedure over another.

PEYRONIE'S DISEASE: A REVIEW OF ETIOLOGY, DIAGNOSIS, AND MANAGEMENT

Peyronie's Disease (PD) is a superficial fibrosing disorder of the penis resulting in plaque formation and penile deformity. Once considered rare, PD has more recently been found in up to 13% of men, and can negatively affect sexual and psychosocial function of both patients and their partners. While the etiology of PD is unclear, it is thought to result from an inciting traumatic event followed by aberrant fibrosis or dysregulated wound healing. The evaluation of men presenting with PD includes a detailed history and physical exam, focusing on the penis in both the flaccid and erect states. PD is often associated with erectile dysfunction (ED), as well as several other comorbidities. Laboratory testing is not needed to diagnose PD, although given the associations between PD and systemic diseases including hypogonadism, diabetes, and cardiovascular disease, screening and work-up for these conditions in men with PD may be warranted. Treatment modalities for PD are diverse and include oral, topical, intralesional, mechanical, and surgical therapies. Oral, topical, and mechanical therapies generally have little evidence supporting their efficacy. Several intralesional therapies, including interferon α2b and collagenase Clostridium hystiolyticum have demonstrated efficacy in the treatment of PD. Surgical treatment, indicated in men with significant, stable deformity, includes plication of the tunica albuginea, plaque incision/excision and grafting, and placement of inflatable penile prosthesis (IPP) with or without additional maneuvers to achieve desired results, and has high success rates.

Outcomes of surgical treatment of Peyronie's disease

The aims of the present review were to assess the literature on published outcomes and complications associated with surgical treatments for Peyronie's disease (PD) and to assist clinicians in the effective management of PD by increasing understanding and awareness of the outcomes associated with current surgical treatment options. A PubMed literature search was conducted to identify relevant, peer-reviewed clinical and review articles published between January 1980 and October 2013 related to outcomes of surgical correction of PD. Search terms for this non-systematic review included 'Peyronie's disease', 'outcomes', 'complications', 'erectile dysfunction or ED', 'patient expectation', and 'patient satisfaction'; search terms were searched separately and in combination. Case studies and editorials were excluded, primary manuscripts and reviews were included, and bibliographies of articles of interest were reviewed and key references were obtained. Assessment of the study design, methodology, clinical relevance and impact on the surgical outcomes of PD was performed on the sixty-one articles that were selected and analysed. Currently, there are several investigational minimally invasive and non-surgical treatment options for PD; however, surgical treatment remains the standard of care for patients with stable disease and disabling deformity or drug-resistant erectile dysfunction. Each of the different surgical procedures that are used for treatment of PD, including tunical shortening, tunical lengthening (plaque incisions or partial excision and grafting), and use of inflatable penile prostheses, carries its own advantages and disadvantages in terms of potential complications and postoperative satisfaction. Because of the variety of ways that PD may present in affected patients, no single, standard, surgical treatment for this disorder has prevailed and multiple variations of each type of procedure may exist. Surgical outcomes of the most commonly used procedures are not substantially different; therefore, the appropriateness of each treatment option may often depend on disease and patient characteristics (e.g. deformity and erectile function). Surgical algorithms have been published to guide surgeons and patients through the selection of surgical procedures in the absence of conclusive, long-term outcome data. Accumulating data on outcomes associated with established procedures, modifications to these procedures, and new surgical techniques and materials may serve to further guide practice and refine evidence-based selection of the surgical approach.

Measurement of endothelial dysfunction via peripheral arterial tonometry predicts vasculogenic erectile dysfunction

Introduction

Endothelial cell dysfunction is associated with cardiovascular disease and vasculogenic erectile dysfunction (ED). Measured via Peripheral Artery Tonometry (PAT), endothelial dysfunction in the penis is an independent predictor of future cardiovascular events.

Aim

Determine whether measurement of endothelial dysfunction differentiates men with vasculogenic ED identified by duplex ultrasound from those without.

Methods

A total of 142 men were retrospectively assessed using patient history, penile duplex ultrasonography (US) and PAT (EndoPAT 2000). ED was self reported and identified on history. Vasculogenic ED was identified in men who exhibited a peak systolic velocity (PSV) of ≤25 cm/s obtained 15 minutes following vasodilator injection. The reactive hyperemia index (RHI), a measurement of endothelial dysfunction in medium/small arteries and the Augmentation Index (AI), a measurement of arterial stiffness, were recorded via PAT.

Results

Penile duplex US separated men into those with ED (n=111) and without (n=31). The cohort with ED had a PSV of 21±1 cm/s (left cavernous artery) and 22±1 cm/s (Right). The control group without ED had values of 39±2 cm/s (Left) and 39±2 (Right). Given the potential for altered endothelial function in diabetes mellitus, we confirmed that hemoglobin A1c, urinary microalbumin, and vibration pulse threshold were not different in men with vasculogenic ED and those without. RHI in patients with ED (1.85±0.06) was significantly decreased compared to controls (2.15±0.2) (p<0.05). The AI was unchanged when examined in isolation, and when standardized to heart rate.

Conclusions

Measurement of endothelial function with EndoPAT differentiates men with vasculogenic ED from those without. RHI could be used as a non-invasive surrogate in the assessment of vasculogenic ED and to identify those patients with higher cardiovascular risk.

A critical analysis of the surgical outcomes for the treatment of Peyronie's disease

Peyronie’s disease (PD) is a relatively common condition, which can impair sexual function and result in emotional and psychological distress. Despite an abundance of minimally invasive treatments, few have confirmed efficacy for improving penile curvature and function. Surgical therapies include many different techniques and are reserved for patients with stable disease of ⩾12 months’ duration. We searched PubMed for all articles from 1990 to the present relating to the surgical management of PD. Preference was given to recent articles, larger series, and those comparing various techniques and/or materials. Outcomes were subsequently analysed and organised by surgical technique and the graft material used. Available surgical techniques include plication/corporoplasty procedures, incision and grafting (I&G), and placing a penile prosthesis with or without adjunctive procedures. Although several surgical algorithms have been reported, in general, plication/corporoplasty procedures are reserved for patients with adequate erectile function, simple curvatures of <60°, and with no deformities (hour-glass, hinge). I&G are reserved for complex curvatures of >60° and those with deformities. Penile prostheses are indicated for combined erectile dysfunction and PD. Overall outcomes show high rates of improved curvature and patient satisfaction, with mildly decreased erectile function with both plication and the I&G procedure (I&G >plication) and decreases in penile length (plication >I&G). Surgical management of PD remains an excellent treatment option for patients with penile curvature precluding or impairing sexual activity. Surgical algorithms are available to assist treating clinicians in appropriately stratifying surgical candidates. Additional research is needed to identify optimal surgical techniques and materials based on patient and disease characteristics.

Standard operating procedures for Peyronie's disease

INTRODUCTION

Peyronie's disease (PD) refers to a penile deformity that is associated with sexual dysfunction.

AIM

To provide recommendations and Standard Operating Procedures (SOPs) based on best evidence for diagnosis and treatment of PD.

METHODS

Medical literature was reviewed and combined with expert opinion of the authors.

MAIN OUTCOME MEASURES

Recommendations and SOPs based on grading of evidence-based medical literature.

RESULTS

PD is a fibrotic wound-healing disorder involving the tunica albuginea of the corpora cavernosa. The resulting scar is responsible for a variety of deformities, including curvature, shortening, narrowing with hinge effect, and is frequently associated in the early phase with pain. Patients frequently experience diminished quality erections. All of these conditions can compromise sexual function for the affected male. The etiopathophysiology of PD has yet to be clarified and as a result, effective, reliable, mechanistic directed non-surgical therapy is lacking.

CONCLUSIONS

The management of PD consists of proper diagnosis and treatment, ranging from non-surgical to surgical interventions. The main state of treatment for PD rests at this time on surgical correction that should be based on clear indications, involve surgical consent, and follow a surgical algorithm that includes tunica plication, plaque incision/partial excision and grafting, and penile prosthesis implantation.

Surgery for Peyronie's disease

Peyronie's disease (PD) is most simply referred to as a fibrotic wound-healing disorder of the tunica albuginea. It is both a physically and psychologically devastating disorder that causes penile deformity, curvature, hinging, narrowing and shortening, which may compromise sexual function. Although a variety of non-surgical treatments have been suggested, none to date offer a reliable and effective correction of the penile deformity. As a result, surgery remains the gold standard treatment option, offering the most rapid and reliable treatment which will be the focus of this article. We review the preoperative evaluation, surgical algorithm, graft materials and postoperative management of PD. Outcomes for tunical shortening, tunical lengthening and penile prosthesis placement for penile straightening are reviewed. Tunica albuginea plication is the preferred method of straightening for men with adequate rigidity and less severe disease defined as curvature less than 70° without narrowing/hinging. Men who have more severe, complex deformity, but maintain strong preoperative erectile function should be considered candidates for straightening with plaque incision or partial excision and grafting. Finally, for those men who have inadequate rigidity and PD, penile prosthesis placement with straightening is the best approach to address both problems.

A retrospective comparative study of traction therapy vs. no traction following tunica albuginea plication or partial excision and grafting for Peyronie's disease: measured lengths and patient perceptions

INTRODUCTION

Loss of penile length is a recognized and common consequence of Peyronie's disease (PD). Traction therapy (TT+) has been reported to decrease post-op length loss as well as increase stretched penile length (SPL) prior to surgery.

AIM

The aim of this study was to study patient outcomes with penile length change and patient satisfaction after surgery following tunica albuginea plication (TAP) and partial plaque excision and grafting (PEG) with or without postoperative TT.

METHODS

Retrospective analysis was performed from our cohort of Peyronie's reconstructive surgery between 2007 and 2010. SPL was measured dorsally from pubis to corona and recorded at the initial office visit and then compared to most recent postoperative visit. Patients were then stratified by procedure and whether TT was used (TT+ and TT-; TAP N = 52 [27 TT+ and 25 TT-] and PEG N = 59 [36 TT+ and 23 TT-). Traction therapy was initiated for >2 hours a day for 3 months typically starting 3-4 weeks postoperatively. A non-validated mailed questionnaire assessed patient perceptions.

RESULTS

Mean length change seen in TAP (TT+) was 0.85 cm (0.25-1.75) vs. -0.53 cm (-1.75 to 0.5) in TAP (TT-) (P < 0.001). The mean length change seen in PEG (TT+) was 1.48 cm (0-6) vs. PEG (TT-) 0.24 cm (-1 to 2.5 cm) (P < 0.001). Sixty-one percent of surveys were returned; 85% lost length prior to the initial office evaluation, with an average of -2.5 cm lost. Importantly, in those who used traction, there was no perceived length loss, 58% reported a mean erect length gain of 1.1 cm. However, only 54% of all patients were satisfied with their current erect length.

CONCLUSIONS

Loss of length in men with PD remains a serious concern. It appears that postoperative TT can result in length preservation, and in many, a measured and perceived length gain following correction of the curvature.

Treatment of Peyronie's disease: 2012 update

Peyronie's disease (PD) is the occurrence of a fibrous inelastic scar of the tunica albuginea of the penis. It is a relatively common disorder among men, with a reported prevalence of 3% to 8%. It is often associated with penile pain, anatomical deformities in the erect state, and difficulty with intromission. Because the exact pathophysiology of PD remains unknown and standards for evaluating or reporting treatment outcomes are unclear, research on effective therapies has been limited. The benefits of nonsurgical treatment options are conflicting and further controlled studies are required before any therapy can be fully recommended. The success of surgery has been well documented; however, surgery is invasive and costly and carries potential side effects. Patients who report stable disease that has been present for longer than 12 months and who experience penile deformity preventing satisfactory sexual intercourse are best suited for surgery. Additionally, failed conservative management and a patient's preference for definitive correction are important additional indications for surgical treatment.

The role of Nesbit's procedure in surgical reconstruction of penile deviation

Objective: We review our results after surgical reconstruction with the Nesbit’s procedure for congenital or acquired penile deviation.

Patients and methods: Etiology of penile deviation, surgical outcome for straightening the penis, postoperative patient satisfaction and clinical findings were evaluated for 5 patients undergoing Nesbit’s procedure followed by a Medline review of contemporary literature regarding alternative surgical techniques. Follow-up included clinical examination, self-photography on erection and a standardized interview with erectile dysfunction assessment using IIEF-5 questionnaire.

Results: Overall patient satisfaction was 100% in two patients, 2 patients were partly satisfied and 1 patient reported no satisfaction because of severe penile shortening with insufficiency for sexual intercourse postoperatively. Preoperative mean angulation of the penis was 42°. Four patients had Peyronie’s disease and 1 patient’s curvature resulted from an untreated penile fracture during sexual intercourse.

Conclusion: The Nesbit technique can give satisfactory results for mild and moderate penile curvature. However, each technique for the reconstruction of penile deviation has its own advantages and disadvantages. Therefore proper patient selection has a major impact on further outcome.

Long-term results of the surgical treatment of Peyronie's disease with Egydio's technique: a European multicentre study

The long-term outcomes of 157 patients affected by Peyronie's disease (PD) who underwent penile straightening with Egydio's technique between January 2004 and December 2008 are reported. Only patients with PD who were stable for at least 6-12 months prior to surgery were enrolled in this study. Preoperative assessment included a dynamic echo colour Doppler ultrasound scan to evaluate the degree of penile deformity and the peak systolic velocity in the cavernosal arteries and an assessment of erectile function with the administration of the International Index of Erectile Function 5 (IIEF-5) questionnaire. Stretched penile length was recorded pre- and postoperatively. Surgical complications, cosmesis and sexual function, patient satisfaction and postoperative erectile function were assessed postoperatively at 3 months, 1 year and 2 years, respectively. After a median follow-up period of 20 months (range: 12-24 months), we found that mild residual curvature (12%) and glans hypoesthesia (3%) were the only causes of partial dissatisfaction. No rejection of the graft was observed. All patients recovered their ability to penetrate with no difficulty. In addition, an intraoperative average increase of 2.5 cm (range: 1.7-4.1 cm) in stretched penile length was recorded, with all patients engaging in penetrative sexual intercourse. In conclusion, this procedure represents a safe and reproducible technique for the correction of penile curvature resulting from PD and yields excellent cosmetic and functional results.

Medium-term follow-up of plaque incision and porcine small intestinal submucosal grafting for Peyronie's disease

The best surgical option for the management of severe cases of Peyronie's disease is currently a matter of debate. To determine medium-term outcomes and complications after treatment of severe Peyronie's disease by porcine small intestinal submucosa (SIS) grafts, we retrospectively reviewed 33 consecutive plaque incisions followed by 4-ply SIS grafting in 28 patients (2002-2009). Postoperative complications, penile length preservation, de novo ED, penile curvature correction and curvature recurrence rates were recorded. Median patient age was 54 years (38-69 years). Median preoperative curvature was 90° (30-90°) (stable for at least 6 months). Six patients (21%) had preoperative ED. There were few postoperative complications (no cases of infection, haematoma (n=2), penile hypoesthesia (n=1), patch rejection and migration (n=1)). Subjective penile shortening and de novo ED were observed in 7 (25%) and 3 (11%) patients, respectively. The success rate for the procedure (straight penis or curvature ≤20° and ability to have intercourse) was 67% (22/33). Four patients achieved curvature correction after a repeat procedure with a new SIS graft. Eleven patients experienced recurrence within 3 months of surgery. After a median follow-up of 9 months (3-94), 22 patients (79%) had a satisfactory curvature correction.

Safety and Tolerability of Local Treatment with Iloprost in Patients with Peyronie's Disease. A Phase 1 Pilot Study and Proposal of a new Symptom Questionnaire

Purpose

Intralesional therapy is a less invasive method for the treatment of Peyronie's disease. The objective of this study was to evaluate safety and tolerability of intralesional injections of lloprost (I2 Prostacyclin analogue) for its property to suppress in fibroblasts CTFG (Connective tissue growth factor) production, which acts in concert with TGF-β to stimulate the fibrotic process.

Methods

Nineteen patients with Peyronie's disease were preliminarily evaluated by considering the degree of penile curvature, plaque size and local and systemic symptoms. Each patient then received weekly intralesional injections of 200ng of lloprost in 1 ml of normal saline for 4–5 weeks. If tolerated, the single dose increased weekly to the maximum of 400 ng (2 mL).

Results

The treatment has shown that all patients seem to well tolerate a 200 ng lloprost dose; 7 of them reached a 300 ng dose and 6 tolerate a 400 ng dose without showing side effects. There was no placebo control group in this study. To evaluate the efficacy of the treatment, the absence of objective parameters (except for the auto-photograph of penis in erection) led us to develop a subjective questionnaire that was given to all patients to assess sexual function, pain reduction, ecc.

Conclusions

Due to the relatively small size of the sample, the efficacy evaluation has been restricted to check the questionnaire reliability. Iloprost is well tolerated to a dose of 400ng in the local treatment of Peyronie's disease.

The management of Peyronie's disease: evidence-based 2010 guidelines

INTRODUCTION

The field of Peyronie's disease is evolving and there is need for a state-of-the-art information in this area.

AIM

To develop an evidence-based state-of-the-art consensus report on the management of Peyronie's disease.

METHODS

To provide state-of-the-art knowledge regarding the prevalence, etiology, medical and surgical management of Peyronie's Disease, representing the opinion of leading experts developed in a consensus process over a 2-year period.

MAIN OUTCOME MEASURES

Expert opinion was based on grading of evidence-based medical literature, widespread internal committee discussion, public presentation, and debate.

CONCLUSIONS

The real etiology of Peyronie's disease and the mechanisms of formation of the plaque still remain obscure. Although conservative management is obtaining a progressively larger consensus among the experts, surgical correction still remains the mainstay treatment for this condition.
