[PMID: 38977232 DOI: 10.1016/j.cellsig.2024.111286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2024] [Revised: 06/28/2024] [Accepted: 07/02/2024] [Indexed: 07/10/2024]
Abstract
BACKGROUND Peyronie's disease (PD) causes benign plaques or induration in tunica albuginea (TA). Kindlin-2 regulates the TGF-β1/Smad3 pathway, which accelerates kidney fibrosis. The study is aimed mainly to investigate the impact of Kindlin-2 on PD formation and its signaling pathways, notably the TGF-β/Smad pathway in the presence of TGF-β1. METHODS In this mouse investigation, adenovirus TGF-β1 was injected into TA to produce PD. The model was successfully induced 45 days later. Western Blot (WB) and immunohistochemistry (IHC) were utilized to measure Kindlin-2 in PD model tissue. WB and immunofluorescence assays were utilized to confirm the impact of TGF-β1 on Kindlin-2 levels in vitro. The interaction among Kindlin-2, TβRI, and Smad3 was detected using immunoprecipitation (IP) experiments. We examined how TGF-β1 affects Smad3 phosphorylation and downstream gene activation process. Finally, Kindlin-2 and the level of tissue fibrosis were examined in PD model. RESULTS Kindlin-2 levels were elevated in the TGF-β1-induced PD model, confirming that TGF-β1 can increase Kindlin-2 levels in primary PD cells. Moreover, Kindlin-2 mediates Smad3-TβRI interaction, activates p-Smad3, and enhances TGF-β1 target gene expression. In vivo investigations reveal that Kindlin-2 promotes PD development and tissue fibrosis. The regulatory effects of Kindlin-2 need the presence of TGF-β1. Tissue fibrosis can be reduced by downregulating Kindlin-2. CONCLUSION Kindlin-2 does not directly activate Smad3 to induce tissue fibrosis. Instead, it exerts its effect through the combined influence of TGF-β1. Inhibiting Kindlin-2 could potentially be a treatment for PD.

Abstract
Objective Peyronie's disease (PD) is an abnormal wound healing in the penile tunica albuginea. After fibrotic plaque excision, different graft materials have been used to repair the defects, but the optimal graft remains unknown. This study aimed to compare the functional outcomes of testicular tunica vaginalis grafts and bovine pericardium grafts in patients with severe PD. Methods A retrospective comparative study was conducted on 33 PD patients undergoing partial plaque excision and grafting from September 2015 to May 2021. The patients were divided into two groups depending on the type of graft used. For 15 patients in Group B, testicular tunica vaginalis grafts were used to repair the defect, while for 18 patients in Group A, bovine pericardium grafts were used. Data of the patient's age, comorbidities, sexual function, penile curvature, postoperative complications, need for further treatment, change in penile length, and satisfaction were gathered and compared between the groups. Sexual function was evaluated using the 5-item version of the International Index of Erectile Function (IIEF-5), and a functional less than 20-degree penile curvature after surgery was considered a successful intervention. Results There was no difference in age, comorbidities, degree of curvature, perioperative IIEF-5, operative time, plaque size, or complication rates. After surgery, a statistically significant improvement in curvature degree (p<0.05) and satisfactory penile appearance (p<0.05) were seen in both groups without any superiority between the two groups (p=0.423 and p=0.840, respectively). With a 30-month follow-up, the IIEF-5 was consistent in both groups, with no statistical significance between the groups (p=0.492). The main change in penile length during the operation was increased and still positive in the last follow-up in both groups without statistical significance (p=0.255 and p=0.101, respectively). Conclusion Partial plaque excision and corporoplasty with both testicular tunica vaginalis or bovine pericardium grafts are equally effective in treating males with clinically significant PD.

Abstract
Background Peyronie's disease (PD) is a localized fibrosis of tunica albuginea, which causes the anatomical and functional changes to the penis. Corporoplasty with grafting is indicated in severe (>60°) and complex curvature. Buccal mucosa is the most favored autologous graft material nowadays. The ventrolateral aspect of lingual mucosa has similar histological features to the rest of the oral cavity. Methods This study aimed to test the efficacy, safety, durability, and reproducibility of corporoplasty with lingual mucosal graft (LMG) in the surgical treatment of PD in terms of surgical outcome, sexual function, and donor site complications. This prospective study included 19 patients of PD with severe and complex curvature, who underwent corporoplasty with LMG. Surgical and functional outcomes were assessed at follow-up planned at 2 weeks, 3 months, 6 months, 1 year, and 2 years. Results The mean operative time was 126.31 ± 21.45 min. Additional Nesbit's plication to correct the residual deformity was required in 26% (5 / 19) of patients. Straightening of the penis (curvature <10°) was achieved in 89% (17 / 19) of patients. Increase in the penile length (>1 cm) postoperatively was achieved in 63% (12 / 19) of patients and a shortening of penis occurred in 5% (1 / 19) of patients. Newer onset erectile dysfunction developed in 11% (2 / 19) of patients, and patient and partner satisfaction rates were 89% (17 / 19) and 84% (16 / 19), respectively, in a mean follow-up of 20.66 ± 5.37 months. Donor site complications were minimal and no patient had any salivary changes or speech disturbances. Conclusion LMG provided excellent short-term results in terms of deformity correction, improved sexual function, and minimal donor site morbidity. The method is simple and reproducible, and multicenter studies with larger number of cases with longer follow-up are required to confirm these favorable results.

Abstract
OBJECTIVES The present study aims to explore the role of shear wave elastography (SWE) in the diagnosis of Peyronie disease (PD). METHODS A total of 59 PD patients and 59 age-matched healthy adult men were included in this study. The B-mode ultrasound (US) and SWE were performed for all subjects, and the Young modulus (YM) values of the corresponding regions of the penis in the PD and control groups were recorded and compared. RESULTS The mean age of the included PD patients and age-matched controls was 53.81 years (SD 9.52, range 32-73). On B-mode US evaluation, 41 (69.5%) of 59 included PD patients were found to have penile plaques, and the remaining 18 (30.5%) patients had no evidence of penile plaque. After evaluation using SWE, the YM values in the penile plaque region of these 41 patients with penile dysplasia were found to be significantly higher (60.29 kPa ± 19.95) than those outside the plaque (in the same patient) (21.05 kPa ± 4.58) and in the same penile region of the control group (20.59 kPa ± 4.65) (P < .001). In the remaining 18 PD patients, the results showed that the YM value of the abnormal penile region in the PD patients (56.67 kPa ± 13.52) was significantly higher than the YM value outside the abnormal penile region in the same patients (22.79 kPa ± 4.31) and in the same penile region in the control group (19.87 kPa ± 3.48) (P < .001; P < .001). CONCLUSIONS In conclusion, this study showed that SWE as a non-invasive technique is useful in identifying and differentiating penile plaques in PD patients and is a simple, rapid and complementary method to B-mode US.

The effect of penile traction device in men with Peyronie's disease on penile curvature, penile length, and erectile dysfunction: a systematic review and meta-analysis. Transl Androl Urol 2023; 12:1673-1685.

Abstract
Background Peyronie's disease (PD) results in curvature, pain, and erectile dysfunction (ED). Penile traction devices (PTDs) are a non-invasive treatment option for PD by applying mechanical forces to elicit biochemical responses that reduce curvature and improve penile function. In the present study, we systematically reviewed and analyzed the literature investigating the use of PTD to treat PD. Methods We have conducted electronic and manual search strategies within the databases and included articles to find relevant studies. A total of Five studies met all the predefined inclusion criteria and were selected for inclusion in the review. Outcomes assessed are penile length, penile curvature, and erectile function (EF). The study population consisted of patients with PD, the intervention was penile traction therapy (PTT), the comparison was matched placebo or follow-up, and the study design was randomized controlled trials (RCTs) or cohort studies. The Cochrane risk of bias assessed the studies' quality for randomized studies and the Newcastle-Ottawa scale (NOS) for non-randomized observational studies. All statistical analyses were performed using R software. Results were considered statistically significant for P<0.05. Results Only five studies met inclusion and exclusion criteria and were published between 2014 and 2021. The sample sizes range [51-110], totaling 419, with a mean of 83.8 patients-the follow-up with a mean of 6.75 months. This meta-analysis evaluated the efficacy of PTD on curvature degree, penile length, and EF in patients. There is a significant positive effect on the curvature degree (P=0.0373), while there is no significant effect on penile length and EF (P=0.5315 and 0.1010), respectively. They are Indicating low heterogeneity with an estimated total heterogeneity of 0. Overall, the available evidence does not support the efficacy of the intervention for penile length or EF. Conclusions The current evidence suggests that PTDs can be a safe and effective treatment option for men with PD to reduce penile curvature. However, further research, including more RCTs with extended follow-up periods, is needed to fully understand their efficacy and determine the ideal timing and patient subtypes that would benefit from PTD.

Abstract
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.

Penile Extra-Tunical Graft Reconstruction of Peyronie's Disease Concavity Deformities. Urology 2021; 158:237-242. [PMID: 34474042 DOI: 10.1016/j.urology.2021.07.039] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 07/11/2021] [Accepted: 07/14/2021] [Indexed: 11/23/2022]
Abstract
OBJECTIVES To report our initial experience with the extra-tunical grafting (ETG) procedure. This procedure was recently introduced by UCSF investigators as a tunica-sparing technique for management of penile concavity deformities. METHODS We retrospectively reviewed records of patients who underwent ETG at our tertiary-care referral center between 2017 - 2020. A collagen graft made from bovine pericardium (Lyoplant) was placed overlying the defect without violating the tunica albuginea or mobilizing the neurovascular bundle. The stretched penile length (SPL) and circumference at the location of deformity were measured intra-operatively. Patient reported outcomes were evaluated by an anonymous 10-question online survey. RESULTS 19 men underwent ETG with a median follow-up of 59 (IQR: 24 - 708) days. ETG was performed via either a window (15/19, 78%) or a de-gloving (4/19, 21%) incision with concomitant penile plication performed in 16/19 (84%) patients. Penile circumference increased by an average of 1.4 cm + 0.5 (P = 0.03) at the location of deformity, while pre- and post-operative SPL were similar (14.0 + 1.4 vs 14.0 + 1.3 cm, P = 0.95). Overall patient satisfaction was reported by 13/15 (86%) patients. Twelve out of 15 (80%) patients reported concavity deformity to be "improved", with 73% reporting "much better". Among 8 patients with follow up greater than six months, graft palpability was reported in 4/8 (50%) patients but was not bothersome. CONCLUSION The ETG procedure appears to be safe and effective for the treatment of penile concavity deformities. Patient outcomes and satisfaction are favorable at intermediate follow up.

Abstract
Peyronie's disease (PD) is a fibroproliferative disease of the penis. Since little is known about the molecular pathogenesis of PD, we compared the biochemical make-up of PD plaques with normal tunica albuginea to clarify pathological processes in the scarred tissue. Protein and mRNA levels were measured in plaques and in unaffected pieces of the tunica albuginea. We investigated the presence of myofibroblasts, the deposition of collagens, and some key elements of Wnt and YAP1 signaling at protein level. The expression of 45 genes, all related to collagen homeostasis and extracellular matrix proteins, was quantified. In plaques, more myofibroblasts were present, and we observed an activation of Wnt signaling and YAP1 signaling. Increased levels of the collagens types I and III confirm the fibrotic nature of plaques. The mRNA ratio of collagen types III, IV, and VI to type I was increased. The expression of lysyl hydroxylase 3 was higher, whereas a decreased expression level was seen for fibronectin and cathepsin K. The biochemical composition of plaques was different from unaffected tunica albuginea: the relative and absolute abundance of various extracellular matrix proteins were changed, as well as the quality of collagen and the level of the collagen-degrading enzyme cathepsin K.

Abstract
INTRODUCTION Peyronie's disease results in penile curvature, shortening, instability, or pain upon erection-hindering sexual performance and leading to psychological distress. Despite extensive research, surgery is still the mainstay of treatment. OBJECTIVE To present an organized description of the most common surgical techniques used in the correction of Peyronie's disease and to propose a surgical algorithm to guide management. METHODS Using PubMed, we reviewed the published literature regarding surgical treatment of Peyronie's disease and its outcomes. We identified original articles, review articles, and editorials addressing the subject, with a focus on surgical techniques, their indications, and outcomes. RESULTS Peyronie's disease can be treated by corporoplasty or penile prosthesis implantation. Corporoplasty includes convex side-shortening procedures and concave side lengthening procedures. It is indicated when the erectile function is adequate. Shortening procedures include excisional, incisional, and plication-only techniques, and lengthening procedures include partial excision or incision followed by grafting. When refractory erectile dysfunction is present, placement of a penile prosthesis with or without further straightening maneuvers is recommended. We reviewed the indications, advantages, disadvantages, and outcomes of the available techniques and proposed a surgical algorithm to guide management. CONCLUSION Penile shortening procedures are usually indicated in curvatures <60°, in penises with adequate length. Partial excision/incision and grafting are indicated for curvatures >60°, hourglass or hinge deformities, and short penises, if the patient's erectile function is adequate. The presence of "borderline" erectile function and/or ventral curvature tilts the choice toward shortening procedures, and refractory erectile dysfunction is an indication for penile prosthesis placement. Peyronie's disease management remains challenging with many options available, making an accurate risk/benefit assessment of each case and meticulous patient counseling critically important.

Abstract
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.

Abstract
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.

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

Abstract
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.

Abstract
Introduction Penile curvature (PC) can be surgically corrected by either corporoplasty or plication techniques. These techniques can be complicated by post-operative: penile shortening, recurrent PC, painful/palpable suture knots and erectile dysfunction. Objective To avoid the complications of corporoplasty and plication techniques using a new technique: combined plication-incision (CPI). Materials and Methods Two groups (1&2) were operated upon: group 1 using CPI and group 2 using the 16-dot technique. In CPI, dots were first marked as in 16 dot technique. In each group of 4 dots the superficial layer of tunica albuginea was transversely incised (3-6mm) at the first and last dots. Ethibond 2/0, passed through the interior edge of the first incision plicating the intermediate 2 dots and passed out of the interior edge of the last incision, was tightened and ligated. Vicryle 4/0, passed through the exterior edges of the incisions, was tightened and ligated to cover the ethibond knot. Results Twelve (57.1 %) participants in group 2 complained of a bothering palpable knot compared to none in group 1 with statistically significant difference (P=0.005). Postoperative shortening (5mm) of erect penis, encountered in 9 participants, was doubled in group 2 but with insignificant difference (P>0.05). Post-operative recurrence of PC, was encountered in only 1 (4.8%) participant in group 2, compared to none in group 1, with insignificant difference (P>0.05). Post-operative erectile rigidity was normally maintained in all participants. Conclusion The new technique was superior to the 16-dot technique for correction of PC.

Abstract
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.

Abstract
Background The inflatable penile prosthesis (IPP) is typically the preferred implant for Peyronie’s disease (PD) and malleable penile prostheses (MPPs) have been discouraged. Aims To evaluate the effectiveness and patient satisfaction of the MPP vs IPP in patients with PD. Methods Men with PD and erectile dysfunction who elected for penile implant surgery constituted the study population. Preoperatively, demographic and comorbidity parameters were recorded. Curvature was measured with a goniometer at maximum rigidity after intracavernosal injection of a vasoactive agent. Postoperatively, overall satisfaction was measured at 3, 6, 12, and 24 months on 5-point Likert scale from 1 (dissatisfied) to 5 (very satisfied). Results 166 men with a mean age of 59 ± 10 years were analyzed. The mean preoperative curvature in the entire cohort was 65° (range = 30–130°). 94% of patients with MPP had total resolution of their curvature at the end of the operation, whereas 8 patients (6%) had residual curvature (25–40°). In the IPP group 25 of 30 (83.3%) had a straight penis at the end of surgery, whereas 5 of 30 (16.7%) had residual curvature, with the mean magnitude being 33° in the MPP group and 30° in the IPP group. 86% of all patients had diabetes. There were no differences between the 2 implant groups in age, hemoglobin A1c, body mass index, or smoking status. The mean patient satisfaction was 4.42 ± 0.70 (range = 2–5) and there was no difference between the 2 groups. The mean follow-up period was 23.4 months (range = 6–29 months). Conclusion We found that the MPP is as effective as the IPP in curvature correction in patients with PD, with similar patient satisfaction for the 2 groups. Habous M, Farag M, Tealab A, et al.

Abstract
Purpose Epigenetic modifications, such as histone acetylation/deacetylation and DNA methylation, play a crucial role in the pathogenesis of inflammatory disorders and fibrotic diseases. The aim of this study was to study the differential gene expression of histone deacetylases (HDACs) in fibroblasts isolated from plaque tissue of Peyronie's disease (PD) or normal tunica albuginea (TA) and to examine the anti-fibrotic effect of small interfering RNA (siRNA)-mediated silencing of HDAC7 in fibroblasts derived from human PD plaque. Materials and Methods For differential gene expression study, we performed reverse-transcriptase polymerase chain reaction for HDAC isoforms (1–11) in fibroblasts isolated from PD plaque or normal TA. Fibroblasts isolated from PD plaque were pretreated with HDAC7 siRNA (100 pmol) and then stimulated with transforming growth factor-β1 (TGF-β1, 10 ng/mL). Protein was extracted from treated fibroblasts for Western blotting. We also performed immunocytochemistry to detect the expression of extracellular matrix proteins and to examine the effect of HDAC2 siRNA on the TGF-β1-induced nuclear translocation of Smad2/3 and myofibroblastic differentiation. Results The mRNA expression of HDAC2, 3, 4, 5, 7, 8, 10, and 11 was higher in fibroblasts isolated from PD plaque than in fibroblasts isolated from normal TA tissue. Knockdown of HDAC7 in PD fibroblasts inhibited TGF-β1-induced nuclear shuttle of Smad2 and Smad3, transdifferentiation of fibroblasts into myofibroblasts, and abrogated TGF-β1-induced production of extracellular matrix protein. Conclusions These findings suggest that specific inhibition of HDAC7 with RNA interference may represent a promising epigenetic therapy for PD.

Abstract
With the increased prevalence of Peyronie’s disease (PD) among men, there is also an up-rise of associated erectile dysfunction (ED) which can be devastating psychologically and sexually to most men. A wide range of therapies including medical and surgical procedures are available to satisfactorily address this condition. However when ED coexists, the gold standard treatment is penile prosthetic prosthesis (PP) with or without additional straightening procedures. We herein systematically review the contemporary literature addressing the role of the PP in the management of PD with concomitant ED with particular emphasis on patient’s satisfaction, outcomes and safety.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
PURPOSE This study was designed to evaluate the efficacy of medical treatment of Peyronie's disease. MATERIALS AND METHODS A total of 109 patients with Peyronie's disease who had been treated from January 2011 to December 2014 were retrospectively reviewed in this study. Forty-four patients (Group 1) were treated with 12 mg of potassium para-aminobenzoate daily. Sixty-five patients (Group 2) were treated with combination therapy: tamoxifen (20 mg) and acetyl-L-carnitine (300 mg) twice daily in addition to a phosphodiesterase type 5 inhibitor. Ability to perform sexual intercourse, pain during erection, size of plaque, and penile curvature angle were assessed. RESULTS In Group 1, 30 of 44 patients (68.2%) discontinued treatment within 12 weeks, while 5 patients (7.7%) in Group 2 discontinued treatment. Pain during erection and plaque size were improved in both groups but showed no statistical difference due to the high dropout rate in Group 1. In both groups, penile curvature was improved, but demonstrated no statistical difference between the treatment groups. However, combination therapy demonstrated a better response rate in patients whose penile curvature angle was less than 30° (44.4% vs. 79.1%, p=0.048). The rate of successful sexual intercourse was significantly higher in Group 2 (42.8% vs. 78.3%, p=0.034). The number of patients who underwent surgical correction despite medical treatment was significantly higher in Group 1 (35.7% vs. 13.3%, p=0.048). CONCLUSIONS Early medical combination therapy in Peyronie's disease may present better results in patients whose curvature angle is less than 30°.

Abstract
Peyronie's disease (PD) is a wound healing disorder of the tunica albuginea of the penis. PD is generally categorized into two phases: the early acute inflammatory and late chronic fibrotic. Surgical reconstruction is only recommended during the latter established phase. There are a variety of options when erections are functional. However, when erectile dysfunction is present, the gold standard treatment is the placement of an inflatable penile prosthesis with or without additional straightening procedures. General recommendations include that after implanting and inflating the cylinders, if a clinically significant curvature is present, manual modeling is performed. If a residual curve >30° remains after modeling, then various techniques, including plaque releasing incision, is the next step. Grafting can be considered if tunical defects are >2.0 cm. Causes of corporal fibrosis include complications from an infected implant such as explantation, priapism, penile trauma, and prolonged use of an intracavernosal injection agent. Implant placement in the setting of corporal fibrosis can be technically challenging. Available strategies include incision or excision of the scar, corporotomies with or without grafting, the use of cavernotomes, or other specialized dilators, implant downsizing, and transcorporeal resection.

Abstract
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.

Abstract
Placement of an inflatable penile prosthesis (IPP) is the mainstay of surgical treatment for patients with Peyronie’s disease (PD) and concomitant medication-refractory erectile dysfunction. Special considerations and adjunctive surgical techniques during the IPP procedure are often required for patients with PD to improve residual penile curvature, as well as postoperative penile length. The surgical outcomes and various adjunctive techniques are not significantly different from one another, and selection of the appropriate technique must be tailored to patient-specific factors including the extent of the deformity, the degree of penile shortening, and preoperative patient expectations. The aims of this review were to assess the current literature on published outcomes and surgical techniques involving IPP placement in the treatment of PD. Patient satisfaction and preferences are reported, along with the description and patient selection for surgical techniques that include manual penile modeling, management of refractory curvature with concurrent plication, and correction of severe residual curvature and penile shortening with tunica release and plaque incision and grafting. A thorough description of the available techniques and their associated outcomes may help guide surgeons to the most appropriate choice for their patients.

Abstract
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.

Abstract
INTRODUCTION Peyronie's disease (PD) can be emotionally and sexually debilitating for patients and may negatively impact partner relationships. AIMS This study aims to present an ongoing collaborative care model for patients with PD and to discuss the critical need for integration of patient care among sexual medicine physicians and mental health practitioners or sex therapists. METHODS PubMed searches using the terms "Peyronie's disease" and "natural history," "treatment," "psychosexual," "depression," "relationship," and "partner" were conducted. Expert opinion based on review of the relevant published literature and clinical experience was used to identify meaningful treatment targets for patients with PD within a collaborative care model. MAIN OUTCOME MEASURE Characteristics of PD, medical treatment, and important assessment and treatment targets, including physical, emotional, psychosexual, and relationship concerns, from peer-reviewed published literature and clinical experience. RESULTS PD can result in significant patient and partner distress and relationship disruption. Sex therapy interventions may be directed at acute emotional, psychosexual, and relationship problems that occur during the initial diagnosis of PD, the period following minimally invasive or surgical treatment for PD, or recurring problems over the lifelong course of the disease. Sex therapy to improve self-acceptance, learn new forms of sexual intimacy, and improve communication with partners provides comprehensive treatment targeting emotional, psychosexual, and relationship distress. Ongoing communication between the mental health practitioner and physician working with the patient with PD about key assessments, treatment targets, and treatment responses is necessary for coordinated treatment planning and patient care. CONCLUSIONS Men with PD are more likely now than in the past to see both a sexual medicine physician and a mental health practitioner or sex therapist, and the integration of assessments and treatment planning is essential for optimal patient outcomes.

Abstract
INTRODUCTION Aneurysmal dilatation of the corpora cavernosa can occur because of recurrent priapism in the setting of sickle cell disease. AIM We present the first case of a successful implementation of the reduction corporoplasty technique for treatment of a phallus that was "too large for intercourse." METHODS We describe the presentation of a 17-year-old male with a history of sickle cell disease with a phallus "too large for intercourse." Patient reported normal erectile function and response with masturbation but also reported inability to penetrate his partner due to the enlarged and disfigured morphology. He had three priapismic episodes since the age of 10 that progressively led to an aneurysmal morphologic deformity of his phallus. Evaluation included a magnetic resonance imaging, which revealed true aneurysmal dilatation of bilateral corpora cavernosa in the middle and distal portions, and diffusely hyperplastic tunica. MAIN OUTCOME MEASURE The main outcome measure is the successful management of phallic disfiguration. RESULTS Reduction corporoplasty was performed, and the patient reported intact erectile function without aneurysmal recurrence. CONCLUSIONS Patients with significant corporal aneurysmal defects secondary to recurrent priapism can be successfully managed with reduction corporoplasty.

Penile straightening maneuvers employed during penile prosthesis surgery: technical options and outcomes. Int J Impot Res 2014; 26:182-5. [PMID: 24646675 DOI: 10.1038/ijir.2014.7] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2013] [Revised: 01/01/2014] [Accepted: 01/16/2014] [Indexed: 11/08/2022]
Abstract
Straightening maneuvers (SM), including manual penile modeling, tunical relaxing incisions and corporal reconstruction using grafting techniques, are occasionally required during inflatable penile prosthesis (IPP) implantation to ensure functional penile straightness. The aim of this study was to compare the outcomes of men undergoing SM employed during IPP implantation compared with those wherein these maneuvers were not required. A retrospective review of 391 patients undergoing IPP implantation at the Johns Hopkins Hospital from January 2000 to December 2011 was performed. Patients in whom some SM was employed (SM, n=93, 23.9% of the overall cohort) were compared with those for whom SM was not required (IPP group, n=298). Seven patients were excluded from final analysis (6 patients with IPPs inserted in neophalli (SM group), and 1 patient with incomplete data (IPP group). Patients in whom a SM was used were younger (55.4 vs 62.3 years), more likely to have Peyronie's disease, and less likely to have prostate cancer, radical prostatectomy or to have previously used erectile aids (all P<0.05). Mean operating room time in the SM group was longer (173.8 vs 152.9 min, P=0.003). Within the SM group, modeling was performed in 40 (43%), tunical relaxing incisions in 37 (39.8%) and tunical reconstruction in 16 (17.2%) (most commonly using allograft dermis or pericardium, or synthetic gore-tex grafts). There were no significant differences in terms of device infection (P=0.15), mechanical failure (P=0.23) or erosion (P=0.96). Although limited in size, this cohort study suggests that IPP implantation in men with penile deformity requiring complex reconstruction to achieve straightening may be done proficiently and without increased adverse outcome risk.

Abstract
OBJECTIVE Peyronie's disease (PD) is a progressive fibrotic disorder of the penis that is characterized by formation of collagen plaques on the tunica albuginea of the penis that may result in penile deformity, pain (typically early in the disease course), and often occurs in conjunction with erectile dysfunction. This review's purpose is to raise awareness of PD among primary care physicians, who are likely to provide the initial diagnosis and information to patients. METHODS PubMed was searched for articles related to epidemiology, diagnosis, and management of PD. Reference lists of relevant articles were also examined for further pertinent research. Following the goals of this review, references were selected based on their appropriateness for a primary care audience. RESULTS The symptoms of PD may physically limit intercourse and impose a severe physical and psychological burden. The course of PD includes an early 'inflammatory' phase that may last 1-18 months and a subsequent 'stable' phase. In the early phase, patients may experience penile pain as the tunical plaque develops. During the stable phase, the plaque becomes more organized, penile curvature stabilizes, and the pain usually subsides. Currently, there are no US Food and Drug Administration approved therapies that have shown significant efficacy for PD. Nonsurgical treatment options are often used to manage PD with variable success. Most studies of nonsurgical management of PD are small, poorly controlled, and include patients in variable disease stages. Surgical treatment of PD is reserved for stable patients with erectile dysfunction and penile deformity that impairs sexual function. CONCLUSION PD is frequently undiagnosed. Even when PD is correctly identified, choice of treatment is problematic, based on the limited currently available clinical data demonstrating clinical benefits associated with treatment. Newer medications in clinical testing seem to offer some potential benefit for men with PD, though further research is necessary.

Abstract
INTRODUCTION Sonoelastography is an emerging ultrasound-based technique that allows characterization of tissue stiffness. AIM The aim of this report is to present a case of significant penile curvature with a non-palpable, non-sonographically visualized plaque that was demonstrable with sonoelastography. METHODS A 60-year-old male presented with significant left penile curvature during erections. The penis was evaluated with physical exam followed by B-mode and color Doppler ultrasound. No evidence of plaque was identified with these modalities. Shear wave sonoelastography was pursued to further characterize the patient's Peyronie's disease. RESULTS An area of increased tissue stiffness that correlated with the site of maximum curvature was identified with shear wave sonoelastography and used to target intralesional injection therapy. CONCLUSION Sonoelastography provides an additional way to characterize, localize, and deliver therapy to a lesion in patients with Peyronie's disease and is particularly useful when palpation and B-mode ultrasonography have failed to demonstrate a plaque.
