Critical analysis of surgery for Peyronieʼs disease

Measurement of Oxidative Stress Index (OSI) in Penile Corpora Cavernosa and Peripheral Blood of Peyronie's Disease Patients: A Report of 49 Cases

Peyronie's disease (PD) is a chronic inflammatory disease affecting the penile albuginea. Oxidative stress (OS) is important for the development of the disease; therefore, it seemed interesting to us to directly measure OS at both the site of the disease and in peripheral blood. For a precise OS study, it is necessary to evaluate not only the single results of the total oxidant status (TOS) and total antioxidant status (TAS) but also their ratio: OS index (OSI) (arbitrary unit) = TOS/TAS × 100. This study included 49 PD patients examined and diagnosed in our Peyronie's care center and a control group of 50 cases. We collected blood samples from both the penis and a vein in the upper extremity; we used d-ROMs and PAT-test (FRAS kit) for OS measurement. Pearson's study found a statistical correlation between penile OSI values and PD plaque volumes: p-value = 0.002. No correlation was found between systemic OSI values and PD plaque volumes: p-value = 0.27. Penile OSI values were significantly reduced after the elimination of the PD plaque (p < 0.00001). The mean value of the penile OSI indices in the PD patients after plaque elimination corresponded to 0.090 ± 0.016 (p = 0.004). The comparison between the penile OSI values of the PD patients (with plaque elimination) and the control group revealed no statistically significant differences (p = 0.130). The absence of a correlation between Peyronie's plaque volume and systemic OSI values indicates that it is preferable to carry out the OS study by taking a sample directly from the site of the disease. By carrying out a penile OSI study, it would be possible to obtain a precise plaque-volume-dependent oxidative marker. Even if the study did not demonstrate any correlation between OSI indices and anxious-depressive state, we detected a high prevalence of anxiety (81.6%) and depression (59.1%) in PD patients.

Urologists' knowledge base and practice patterns in Peyronie's disease. A national survey of members of the italian andrology society

Peyronie's disease is a chronic inflammatory disease involving the formation of plaque in the tunica albuginea of the corpora cavernosa, resulting in penis deformity. It is often associated with penile pain, especially in younger patients, but it is not rare for pain to be absent; the disease is also associated with erectile dysfunction and a depressive state in a large percentage of cases.

OBJECTIVE

Aim of our study was to explore the basic knowledge base and diagnostic and therapeutic practice patterns in Peyronie's disease (PD) of a large number of physicians belonging to the Italian Andrology Society (SIA).

METHODS

Our survey is based on two questionnaires which were e-mailed to the members of the SIA. The first questionnaire explored diagnostic and therapeutic practice patterns of SIA physicians, while the second questionnaire focused on their knowledge of the disease, as well as their training and level of experience in the specific field. We then planned to compare our outcomes with similar PD surveys from other countries.

RESULTS

The first questionnaire was answered by 142 SIA physicians. The second questionnaire was answered by 83 SIA physicians. Most respondents (74.6%) chose penile ultrasonography as first-line diagnostic approach and 47.1% prefer to perform a color Doppler ultrasound after pharmaco-induced erection. Concerning the therapeutic practice patterns in active stage of the disease, most respondents (99.29%) prefer conservative medical therapy. Additionally, most respondents (64.78%), when failure of conservative treatment had been established, considered surgical treatment necessary, specifically corporoplasty, which may be associated with other techniques.

CONCLUSIONS

The results of our survey show that, in comparison to their foreign counterparts, Italian SIA uro-andrologists have a more proactive diagnostic approach right from when patients first present. When PD is still in its active stage, SIA uro-andrologists mostly opt for medical therapy. In advanced disease or if conservative treatment fails, our survey indicates a greater preference for surgical treatment. Answers to the theoretical knowledge questions showed that SIA physicians have a good understanding of the disease's etiology, epidemiology, and clinical picture, and of the appropriate indications for treatment.

Advances in stem cell therapy for the treatment of Peyronie's disease

Peyronie's disease (PD) is a connective tissue disorder of the penis characterized by fibrosis and plaque formation within the tunica albuginea. PD is characterized by painful penile curvature that impairs sexual intercourse. Stem cell therapy is one of the recent non-invasive treatment options for patients with PD and it has promising results. Stem cells are undifferentiated cells that are capable of self-renewal and differentiation, promoting the repair of tissues via their immunomodulatory and anti-inflammatory action. Adipose-derived stem cells (ADSC) are used most widely due to their abundant tissue source and ease of isolation. Multiple studies have indicated the efficacy of stem cell therapy as a potential treatment for fibrotic diseases. Clearly, ADSCs may represent a way to treat and prevent PD in both rat and human models. Further clinical studies are needed to confirm the efficacy of stem cell therapy for PD in humans.

Inflatable Penile Prosthesis Placement, Scratch Technique and Postoperative Vacuum Therapy as a Combined Approach to Definitive Treatment of Peyronie's Disease

PURPOSE

Peyronie's disease is a devastating condition resulting in penile malformation, erectile dysfunction, pain and emotional distress. In this prospective, 2 institution study we evaluated a multimodal surgical and mechanical combined approach to the definitive treatment of Peyronie's disease and concomitant erectile dysfunction.

MATERIALS AND METHODS

A total of 145 select patients underwent endocavernous disruption of Peyronie's disease plaques via the scratch technique, followed by inflatable penile prosthesis insertion. Postoperatively patients were assigned to vacuum device therapy for 3 minutes twice daily to continue penile curvature correction. Followup continued for 1 year after surgery. Anatomical and functional results were assessed.

RESULTS

Patients with plaques in the proximal third, middle third and subcoronal areas of the penis had a mean ± SD postoperative residual curvature of 21.5 ± 4.5, 17.3 ± 4.8 and 14.1 ± 3.1 degrees, respectively. After 24 weeks of vacuum therapy the mean penile curvature deviation decreased to 8.7 ± 2.5, 9.1 ± 2.9 and 7.7 ± 0.9 degrees, respectively. The mean IIEF-5 (International Index of Erectile Function) score was 9.8 ± 2.3 preoperatively, 18.9 ± 3.1 at 6 months (p <0.001) and 24.1 ± 3.6 at 1 year (p <0.001). The mean EDITS (Erectile Dysfunction Inventory of Treatment Satisfaction) score at the end of followup was 64.6 ± 11.8. Operative and postoperative complications were minimal.

CONCLUSIONS

Our novel combination of intraoperative and postoperative therapies in the treatment of patients with Peyronie's disease and an inflatable penile prosthesis was safe and efficacious with excellent functional outcomes. Penile curvature corrections were statistically significant and complications were negligible.

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.

Penile Length: Measurement Technique and Applications

INTRODUCTION

Penile size has long been an important fixation in men's lives. On the one hand, a smaller penis has been associated with anxiety and apprehension; on the other hand, a larger penis has generally been related to virility and strength. These perceptions predominate during an erection, when penile size is representative of a man's masculinity.

AIM

To assess adult penile length and summarize average penile length assessments from the literature; analyze how various urologic diseases and therapies affect penile length and volume; and review how surgical treatments for Peyronie's disease, penile prosthesis implantation, and radical prostatectomy can affect penile size to appropriately counsel patients seeking such therapies and set realistic goals for patients.

METHODS

To achieve the aim of this review, we analyzed the literature on penile size and volume and how these can be affected by various urologic diagnoses and therapies. We summarize common diagnoses and therapies that can affect penile size.

MAIN OUTCOME MEASURE

We thoroughly discuss how the aforementioned diagnoses and therapies can negatively affect penile size. In doing so, we allow readers to understand the intricacies of penile size when faced with such diagnoses and therapies in their patients.

RESULTS

Surgical treatments for Peyronie's disease, penile prosthesis implantation for refractory erectile dysfunction, and radical prostatectomy for prostate cancer can lead to a decrease in penile size.

CONCLUSION

Urologists must recognize that the different therapies they offer can affect a man's penile size, often negatively. This in turn can lead to poorer satisfaction outcomes in patients.

Collagenase Clostridium histolyticum in the Treatment of Peyronie's Disease-A Review of the Literature and a New Modified Protocol

INTRODUCTION

Peyronie's disease (PD) is a common condition that results in penile deformity, which makes sexual intercourse difficult or impossible, and causes psychological, emotional, and relationship difficulties for the man affected and his partner. Collagenase Clostridium histolyticum (CCH; Xiapex, Xiaflex) is the first licensed non-surgical treatment option for PD. The safety and efficacy have been demonstrated in two large phase III randomized controlled trials (IMPRESS I and IMPRESS II).

AIM

To review the safety and efficacy of CCH and to introduce a new shortened modified protocol for CCH that was developed by the authors to decrease the cost and duration of treatment.

METHODS

A review of the medical literature on CCH for inclusion in this review was obtained by searching the PubMed (from 1946) and Medline (from 1946) medical databases and from the screening of relevant bibliographies. The search terms Xiapex, Xiaflex, collagenase Clostridial histolyticum, and Peyronie's disease were used. Clinical trials in men with PD and scientific articles relating to pharmacologic data were included in the review. When possible, large, randomized, and well-designed trials were selected.

MAIN OUTCOME MEASURES

Changes in the angle of penile curvature and in the Peyronie's Disease Questionnaire domains.

RESULTS

The clinical trials demonstrate the safety and efficacy of CCH in the treatment of PD. The new modified protocol developed by the authors is as safe and effective as the protocol used in the clinical trials.

CONCLUSION

CCH is the first licensed non-surgical treatment for PD. Its safety and efficacy have been demonstrated in large well-designed clinical trials. The new shortened modified protocol decreases the cost and duration of the treatment without compromising the safety and efficacy of the drug. This alteration will allow more patients to benefit from CCH. Abdel Raheem A, Johnson M, Abdel-Raheem T, et al.

Peyronie's graft surgery-tips and tricks from the masters in andrologic surgery

BACKGROUND

Grafting techniques in the surgical management of Peyronie's disease (PD) are challenging, especially in inexperienced hands. In order to improve surgical outcomes the urologist should follow a standard surgical approach, preferably of an established and reliable grafting technique. The aim of this study is to provide tips and tricks for graft surgery for PD.

METHODS

This report offers a step-by-step tutorial for grafting techniques in PD, especially for the Sealing technique and the partial plaque excision and grafting (PEG) procedure. Two senior surgeons (GH, LAL) describe their surgical technique in detail, and provide important aspects and tips one has to be aware of when performing a grafting technique in patients with PD. Special attention is also paid to preoperative considerations and adequate patient counseling. Moreover, postoperative penile rehabilitation programs are discussed.

RESULTS

Adequate preoperative counseling of patients is crucial, and should include possible adverse effects and negative outcomes, such as persistent or recurrent curvature, diminished sensation at the glans penis, diminished erectile function, or penile shortening. The correct indication for a grafting technique is imperative. There are many surgical details during grafting techniques, which have to be considered in order to achieve the best result possible. These include the correct preparation of the neurovascular bundle, the following partial plaque excision without damaging the underlying erectile tissue, and the sufficient closure of the resulting tunica albuginea defect. Defect closure can be done by grafts like pericardial graft (PEG procedure) or the collagen fleece (Sealing technique). Postoperatively, the patient should refrain from sexual activities for at least 6 weeks, and follow a penile rehabilitation program with Phoshodiesterase-Type-5 inhibitors, manual stretch, penile massage, and penile traction therapy.

CONCLUSIONS

The present paper offers a step-by-step tutorial for grafting techniques in PD, especially for the Sealing technique and the PEG procedure, in order to help the reader to understand major steps during surgery and to avoid pitfalls. Careful patient selection, a reliable and established surgical technique and a postoperative rehabilitation program are main predictors for treatment success. In summary, the ultimate goal should be improved patient care, safety and satisfaction.

A review of surgical strategies for penile prosthesis implantation in patients with Peyronie's disease

The introduction of the inflatable penile prosthesis (IPP) has revolutionized the treatment of patients with both Peyronie's disease (PD) and erectile dysfunction (ED). A thorough literature review was performed in order to review the surgical strategies used to treat PD, using the PubMed online database with the keywords "penile prosthesis", "surgical management" and "Peyronie's disease". Patient satisfaction rates of 72-100% and partner satisfaction rates of 89% have been reported in the literature, although strong preoperative education may be needed to prepare patients for risks such as penile shortening, seen in up to 54% of patients. Three-piece IPPs are most commonly used, and when comparing the two most popular models (AMS 700 CX vs. Coloplast Titan), no significant differences were seen in functional outcomes or patient satisfaction. Simple insertion of an IPP has been shown to resolve curvature in 33-90% of patients, but surgeons may often need to also utilize ancillary straightening procedures for residual curvatures. Manual modeling can correct residual curvature with an 86-100% success rate, but with a 4% risk of urethral injury. When the post-modeling residual curvature exceeds 30 degrees, a plaque-releasing incision or plication is recommended to further reduce curvature. Grafting is recommended if the resulting incisional defect is larger than two centimeters. Alternative straightening techniques such as plication prior to IPP insertion, endoscopic plaque resection, the "scratch technique" and bone saw plaque incision have also been described.

The Outcome of Multiple Slit on Plaque with Plication Technique for the Treatment of Peyronie's Disease

Purpose

To evaluate the postoperative outcome of the multiple slit on plaque plication technique for the treatment of Peyronie's disease.

Materials and Methods

We retrospectively evaluated 22 patients who underwent plaque incision with penile plication for the surgical treatment of Peyronie's disease, who had failed medical treatment between 2009 and 2014. Patients were grouped by preoperative degree of penile curvature into Group I: mild (n=5, 22.7%), Group II: moderate (n=11, 50.0%), and Group III: severe (n=6, 27.3%). After a thorough review of the medical records, we evaluated (a) the correction of the curvature; (b) sexual function; and (c) any penile shortening or other complications.

Results

The mean postoperative follow-up period was 39 months. Complete correction of the curvature was attained in 21 patients (95.5%). As an inevitable complication, minimal penile shortening (<1.5 cm) was reported by 14 patients (82.4%) but did not adversely affect sexual intercourse (0%), and all patients found the extent of penile shortening to be acceptable. Nineteen patients had good erectile function (International Index of Erectile Function >21). The most frequent complication was subcutaneous penile edema in three patients (13.6%), which was resolved within about 3 months following surgery.

Conclusions

As a modified technique, multiple slit on plaque with plication is a simple, minimally-invasive and effective technique for correcting penile curvature regardless of curvature severity. The degree of penile curvature does not significantly predict the amount of penile length loss.

Practical Computerized Solution for Incision and Grafting in Peyronie's Disease

Introduction

Penile curvature correction with plaque incision and graft (PIG) increases the risk of erectile dysfunction (ED) and is associated with mechanical and geometric abnormalities.

Aims

The aim of this study was to create and validate a new PIG technique using minimum graft area to correct simple or complex penile curvature with or without hourglass deformity, while avoiding mechanical and geometric abnormalities.

Methods

Using our cotton fabric model, we created a mathematic solution for PIG with no residual defects. This was applied in nine men who had sufficient penile rigidity while penetrating their respective partners. They underwent fascia lata patch corporoplasty using the new developed technique (iPad [Apple Corp, Palo Alto, CA, USA] app: iGrafter). Subjects answered the 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire preoperatively and at the end of follow-up.

Main Outcome Measures

The main outcome measures used were patient demographics, erectile function, residual curvature, patient satisfaction, graft area, and complications.

Results

After a mean follow-up of 17.8 months, no significant complication was noted. Complete penile straightening was achieved in all patients. The short side of the penis increased a mean of 3 cm in length, and the mean graft area was 12.4 cm². At the end of the follow-up, three patients developed recurrent deformity. One patient presented severe fibrosis in the corpora cavernosa and severe ED. There was no significant difference between the mean preoperative and postoperative IIEF-5 scores (20.6 vs 19.4, respectively). At the end of follow-up, all patients were able to have sexual intercourse (two with and seven without pharmacological aid). Eight of the nine patients were satisfied with the surgical result.

Conclusion

Penile curvature surgical correction using the iGrafter seems to be an efficient and safe procedure, which uses minimum graft area and preserves erectile function after penile rectification, without resulting in residual deformities. Further research is needed to confirm the efficacy of this procedure.

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.

The Egydio geometrical procedure for managing penile curvature using a single relaxing incision: A single-centre experience with 330 patients

Objective

To present our 3-year experience with the Egydio’s geometrical procedure for managing penile curvature with some modifications.

Patients and methods

In all, 330 patients (mean age 51 years) that underwent the Egydio’s procedure as day cases were included in this study.

Results

The mean penile curvature was 45° and 27.3% of the patients reported mild erectile dysfunction (ED) preoperatively. Partial excision of the calcified plaque was performed in 12.1% of the patients. Partial glans necrosis was recorded in one patient, while haematoma was recorded in 9%, and delayed wound healing in 3%. There was residual curvature (mean 20°) requiring reoperation in 8.2% of the patients. In all, 10% of the patients were dissatisfied with their results, while of the remainder, 75.2% were totally satisfied and 14.8% partially satisfied. ED was reported in 31.8% of the patients (moderate: 17.3% and significant: 2.7%).

Conclusions

The Egydio geometrical technique for the treatment of penile curvature seems to be a simple, reproducible, safe, and efficient operation.

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.

All about Peyronie's disease

Peyronie's disease (PD) is an acquired connective tissue disorder of the tunica albuginea of the corpus cavernosum, characterized by excessive fibrosis and plaque formation. PD can result in significant physical and psychological morbidity; as it may prevent intercourse and cause adverse impacts on partner relationships. The exact etiology and pathophysiology remain unclear, and many misconceptions about the disease associations, course and treatment exist.

The disease has two distinct stages. The acute stage is characterized by pain, and disease may progress during this stage. Non-surgical managements at this stage aim to alleviate pain and stabilize the disease. Results for non-surgical treatment are often conflicting. The chronic stage occurs 6–12 months later, where pain disappears and the deformity stabilizes. Surgical treatment is reserved for significant deformity or with inability to penetrative intercourse. The choice of the surgical technique depends on the length of the penis, degree of deformity, erectile function, patients' expectations and surgeon's preference.

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.

Penile traction therapy and Peyronie's disease: a state of art review of the current literature

In recent years, penile traction therapy (PTT) has gained considerable interest as a novel nonsurgical treatment option for men with Peyronie's disease (PD) and short penises. The current published literature suggests that selected cases of PD may benefit from a conservative approach with PTT, resulting in increased penile length and reduction of penile deformity. It appears to be safe and well tolerated but requires a great deal of patient compliance and determination. This article reviews the current literature pertaining to the use of PTT in men with PD, short penises and in the setting of pre- and postprosthesis corporal fibrosis.

Current and emerging treatment options for Peyronie's disease

Peyronie’s disease (PD) is a condition of the penis, characterized by the presence of localized fibrotic plaque in the tunica albuginea. PD is not an uncommon disorder, with recent epidemiologic studies documenting a prevalence of 3–9% of adult men affected. The actual prevalence of PD may be even higher. It is often associated with penile pain, anatomical deformities in the erect penis, and difficulty with intromission. As the definitive pathophysiology of PD has not been completely elucidated, further basic research is required to make progress in the understanding of this enigmatic condition. Similarly, research on effective therapies is limited. Currently, nonsurgical treatments are used for those men who are in the acute stage of PD, whereas surgical options are reserved for men with established PD who cannot successfully penetrate. Intralesional treatments are growing in clinical popularity as a minimally invasive approach in the initial treatment of PD. A surgical approach should be considered when men with PD do not respond to conservative, medical, or minimally invasive therapies for approximately 1 year and cannot have satisfactory sexual intercourse. As scientific breakthroughs in the understanding of the mechanisms of this disease process evolve, novel treatments for the many men suffering with PD are anticipated.

US Imaging in Peyronie's Disease

The aim of this study is to assess the role of ultrasound (US) in Peyronie's Disease (PD). PD is a psychologically and physically devastating disorder that manifests in middle-aged men. Fibrous inelastic plaques in the tunica albuginea, result in palpable penile scar in the flaccid condition and cause painful erections and penile deformity, including penile curvature, hinging, narrowing, and shortening of penis. Penile deformity is the most common (52%) first symptom of PD and is present in 94% of affected men. US is the primary imaging modality of choice due to its easy availability, low risk, and ability to image and quantify both calcified and soft tissue elements of PD. US provides identification of smaller and non-palpable lesions and shows the extent of fibrosis. Detection of calcifications within the plaque suggests stabilization of the disease and provides information useful to select patients for appropriate treatment.

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 vacuum pump therapy to mechanically straighten the penis in Peyronie's disease

OBJECTIVE

to assess the efficacy of vacuum therapy in mechanically straightening the penile curvature of Peyronie's disease (PD).

PATIENTS AND METHODS

Modelling of the tunica albuginea has been shown to be possible during penile implant surgery and this principle has been applied as an alternative conservative therapy. In all, 31 patients with PD (mean duration 9.9 months; mean age 51 years, range 24-71) completed the study. Over a 12-week period, the patients used a vacuum device (Osbon ErecAid, MediPlus, High Wycombe, UK) for 10 min twice daily. The assessment at study entry and at completion after 12 weeks included the International Index of Erectile Function questionnaire, a perceived pain intensity score, stretched penile length measurement and the angle of penile deformity after an intracavernous injection with prostaglandin E1.

RESULTS

there was a clinically and statistically significant improvement in penile length, angle of curvature and pain after 12 weeks of using the vacuum pump. Of the 31 patients, 21 had a reduction in the angle of curvature by 5-25 degrees, three had worsening of the curvature and there was no change in the remaining seven. The curvature was corrected surgically in 15 patients while the remaining 16 (51%) were satisfied with the outcome.

CONCLUSION

vacuum therapy can improve or stabilize the curvature of PD, is safe to use in all stages of the disease, and might reduce the number of patients going on to surgery.

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.

Peyronie's reconstruction for maximum length and girth gain: geometrical principles

Peyronie's disease has been associated with penile shortening and some degree of erectile dysfunction. Surgical reconstruction should be based on giving a functional penis, that is, rectifying the penis with rigidity enough to make the sexual intercourse. The procedure should be discussed preoperatively in terms of length and girth reconstruction in order to improve patient satisfaction. The tunical reconstruction for maximum penile length and girth restoration should be based on the maximum length of the dissected neurovascular bundle possible and the application of geometrical principles to define the precise site and size of tunical incision and grafting procedure. As penile rectification and rigidity are required to achieve complete functional restoration of the penis and 20 to 54% of patients experience associated erectile dysfunction, penile straightening alone may not be enough to provide complete functional restoration. Therefore, phosphodiesterase inhibitors, self-injection, or penile prosthesis may need to be added in some cases.

Surgical correction of Peyronie's disease via tunica albuginea plication or partial plaque excision with pericardial graft: long-term follow up

INTRODUCTION

Limited publications exist regarding long-term outcomes of surgical correction for Peyronie's Disease (PD).

AIM

To report on long-term postoperative parameters including rigidity, curvature, length, sensation, function, and patient satisfaction in men with PD treated surgically via Tunica Albuginea Plication (TAP) or Partial Plaque Excision with Tutoplast Human Pericardial Grafting (PEG).

MAIN OUTCOME MEASURES

Objective and subjective data regarding patients who underwent either TAP or PEG.

METHODS

We report on 142 patients (61 TAP and 81 PEG) with both objective data and subjective patient reports on their postoperative experience. Patients underwent either TAP or PEG following our previously published algorithm. Data was collected via chart review and an internally generated survey, in which patients were asked about their rigidity, straightness, penile length, sensation, sexual function and satisfaction.

RESULTS

Average follow up for TAP patients was 72 months (range 8-147) and 58 months (range 6-185) for PEG patients. At survey time, 93% of TAP and 91% of PEG patients reported curvatures of less than 30o. Rigidity was reportedly as good as or better than preoperative in 81% of TAP and 68% of PEG patients, and was adequate for coitus in 90% of TAP and 79% of PEG patients with or without the use of PDE5i. Objective flaccid stretched penile length measurements obtained pre and postoperatively show an average overall length gain of 0.6 cm (range -3.5-3.5) for TAP and 0.2 cm (range -1.5-2.0) for PEG patients. Sensation was reportedly as good as or better than preoperative in 69% of both TAP and PEG patients; 98% of TAP patients and 90% of PEG are able to achieve orgasm. 82% of TAP patients and 75% of PEG patients were either very satisfied or satisfied.

CONCLUSION

Our long-term results support both TAP and PEG as durable surgical therapy for men with clinically significant PD.

Surgical treatment of Peyronie's disease: choosing the best approach to improve patient satisfaction

AIM

To discuss important points on medical history, preoperative evaluation, real expectations, and selection of the appropriate surgical procedure to improve patient satisfaction after surgical procedures for Peyronie's disease.

METHODS

Recent advances in approaches to Peyronie's disease are discussed based on the literature and personal experiences. Issues concerning surgical indication, patient selection, surgical techniques, and grafting are discussed. Lengthening procedures on the convex side of the penile curvature by means of grafting offer the best possible gain from a reconstruction standpoint. Penile rectification and rigidity are required to achieve a completely functional penis. Most patients experience associated erectile dysfunction (ED), and penile straightening alone may not be enough to restore complete function. Twenty-five patients were submitted to total penile reconstruction on length and girth with concomitant penile prosthesis implant. The maximum length restoration was possible and limited by the length of the dissected neurovascular bundle. The mean age was 55.4 years (32-69 years) and the mean angle of curvature 74.2+/-22.4 degree (0-100 degree). Pericardial grafting was used to cover the defect. The mean follow-up time was 11.2 +/- 5.9 months (3-22 months).

RESULTS

Mean functional penile length gain was 3.40+/-0.73 cm (2-5 cm). Penile prosthesis maintained the penis straight. No infections occurred. Sexual intercourse was restored in all patients and all reported recovered self-esteem.

CONCLUSION

Improving patient satisfaction with the surgical treatment includes proper preoperative evaluation on stable disease, penile shortening, vascular and erectile status, patient decision and selection as well as extensive discussion on surgical technique for restoring functional penis (length and rigidity). Length and girth restoration is very important for self-esteem and patient satisfaction.
