Peyronie's disease is currently considered a wound healing disorder that presents with a fibrous inelastic scar of the tunica albuginea, which is believed to occur in genetically susceptible individuals following trauma to the penis. It is characterized by the development of a palpable scar, which in the erectile state causes a variety of deformities, erectile dysfunction and painful erections, and its pathogenesis is unclear. There are many therapeutic options and each has its advantages and disadvantages. This article outlines the advances in the recent studies of Peyronie's disease.

The incidence of Peyronie's disease has continuously increased during the last 30 years. Because of the better understanding of the basic sciences of the disease, earlier diagnosis and improved medical and surgical treatment, currently patients with Peyronie's disease have a wider range of therapeutic options and may experience a better prognosis, with only few of them in need of prosthesis surgery. This paper reviews the pathogenesis, pathology, diagnosis and treatment of Peyronie's disease.

Extracorporeal shockwave therapy (ESWT) has been widely used in various fields ever since it was first introduced for the treatment of urinary stones in 1983. Recent years see a growing application of ESWT to andrology. Studies show that ESWT can relieve pain in 83% of the patients with Peyronie's disease, and has won favorable comments from 66% of the patients. ESWT can significantly improve the sexual life quality of the patients with organic erectile dysfunction, yields good effect in the treatment of chronic nonbacterial prostatitis, especially in pain relief. ESWT has offered new ideas and options for the treatment of andrological diseases. However, its mechanisms have yet to be clarified by more in-depth basic studies and multi-centered, large-sample randomized controlled trials.

Penile vascular endothelial damage, vasomotor dysfunction, and blood flow deficiency are the major causes of erectile dysfunction (ED). Current management of ED mostly depends on selective phosphodiesterase type 5- (PDE5) inhibitors, which fail for some ED patients. For Peyronie's disease-induced ED, surgical and physical therapies are used in addition to PDE5I medication, but frequently it is difficult to achieve satisfactory results. Recent studies show that the low-intensity extracorporeal shockwave therapy can promote angiogenesis and improve blood flow to the penis, which promises to be a novel effective therapy for ED and Peyronie's disease.

The aim of this article is to assess the outcomes of a low-intensity extracorporeal shock wave therapy (LiESWT) protocol for the treatment of Peyronie's disease (PD). Patients treated for PD were prospectively recorded, and data were retrospectively reviewed. Age, characteristics of fibrous plaques, concomitant treatments, International Index of Erectile Function (IIEF-5), Lue score, and pain score on Likert scale were collected. Patients in acute phase of PD and an angulation of <40° were included. The protocol consisted of 6 weekly sessions of 4000 pulses each, applied from different directions, with a maximal power of 20 W and 8 Hz frequency. We included 39 patients (median age: 56.8 years, interquartile range [IQR]: 35.8-62.2 years). The median number of sessions received per patient was 7.2. After treatment, the median Lue score decreased from 6.8 initially to 3.3 (P = 0.003), the median Likert pain score dropped from 1.8 to 0.7 (P = 0.004), the median plaque size was reduced from 2 cm to 1.2 cm (P = 0.08), and the median penile curvature diminished from 31° to 17° (P = 0.07). On univariate and multivariate analysis, the only predictors of success were younger age (odds ratio [OR] = 0.95, P = 0.03 and OR = 0.91, P = 0.04, respectively) and concomitant use of phosphodiesterase-5 inhibitors (PDE5i; OR = 0.92, P = 0.02 and OR = 0.93, P = 0.01, respectively). LiESWT had a favorable impact on Lue score and notably penile pain, curvature, plaque size, and erectile function in patients treated for PD during the early inflammatory phase, with no side effects. Younger age and concomitant use of PDE5i were the only success predictors.

AIMTo determine retrospectively the safety and efficacy of extracorporeal shock wave therapy (ESWT) in patients with Peyronie's disease.

METHODSFifty-three patients with stable Peyronie's disease underwent ESWT (group 1). Fifteen patients matched with the baseline characteristic of the patients in group 1, who received no treatment, were used as the control (group 2). The patients' erectile function (International Index of Erectile Function [IIEF-5] score), pain severity (visual analog scale), plaque size and degree of penile angulation were assessed before and after the treatment in group 1 and during the follow-up in group 2.

RESULTSThe mean follow-up time was 32 months (range: 6-64 months) in group 1 and 35 months (range: 9-48 months) in group 2. All the patients were available for the follow-up. Considering erectile function and plaque size, no significant changes (P > 0.05) were observed in group 1 before or after the ESWT. A total of 39 patients (74%) reported a significant effect in pain relief in group 1 after ESWT. However, regarding improvement in pain, IIEF-5 score and plaque size, no significant differences were observed between the two groups. In 21 patients (40%) of group 1, the deviation angle was decreased more than 10 degrees with a mean reduction in all patients of 11 degrees (range: 6-20 degrees). No serious complications were noted considering ESWT procedure.

CONCLUSIONESWT is a minimally invasive and safe alternative procedure for the treatment of Peyronie's disease. However, the effect of ESWT on penile pain, sexual function and plaque size remains questionable.

ObjectiveTo investigate the clinical effect of low-intensity extracorporeal shockwave therapy (LI-ESWT) on Peyronie's disease.

METHODSFrom October 2016 to December 2017, we treated 32 cases of Peyronie's disease by LI-ESWT, with the therapeutic index of 0.09 mJ/mm2 and a pulse frequency of 120 beats/min. Each plaque was approached from two angles, each angle with a shockwave output of 900 times, and the larger ones from three points, each with an output of 600 times in addition to 300 times from the distal and proximal ends of the plaque, respectively. All the patients received 12 courses of treatment (2 courses a week) with a break of 3 weeks between the 1st and 2nd 6 courses. Then we observed the plague size and penile curvature of the patients, obtained their scores on the Visual Analogue Scale (VAS) and International Index of Erectile Function 5 (IIEF-5), and recorded their adverse reactions.

RESULTSThe plagues were softened or diminished in different degrees in 9 of the 32 cases and erectile pain was alleviated in 15 cases after treatment. Penile curvature at erection, however, showed no significant improvement. The IIEF-5 scores were increased in 18 of the patients complicated with varied degrees of erectile dysfunction after LI-ESWT. No obvious complications were observed in any of the patients.

CONCLUSIONSLow-intensity extracorporeal shockwave therapy has a certain effect on Peyronie's disease by relieving plague-induced pain and improving the patient's penile erection and quality of life.

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°.

The treatment of Peyronie's disease has been a challenge to urologists, as most of the current oral medications are considered hardly valid and the rest of the therapies require strict control of indications, some of which remain controversial, while the final surgical option may be associated with complications such as penile shortening or erectile dysfunction. Collagenase clostridium histolyticum has been proved to be effective in dissolving the penile cavernosal plaque and approved by the Food and Drug Administration of the USA as the first drug to be used for the treatment of Peyronie's disease. This article presents an introduction to the characteristics, safety, efficacy, and procedures of this new treatment, which may benefit urologists and the patients with Peyronie's disease.

The present paper provides a review of the available non-surgical treatments for Peyronie's disease (PD). A review of published literature on oral, intralesional, external energy and iontophoresis therapies for PD was performed, and the published results of available treatment options reviewed. The authors recommendations for appropriate non-surgical management of PD are provided. Although there are many published reports that show the efficacy of non-surgical therapies for PD, there is a lack of large scale, multicenter controlled clinical trials, which makes treatment recommendations difficult. Careful review of the literature does suggest that there are treatment options that make scientific sense and appear to stabilize the disease process, reduce deformity, and improve function. Offering no treatment at all will encourage our patients to pursue alternative treatments, which might do harm, and misses the opportunity to do some good. Clearly further work is necessary to develop safe and effective non-surgical treatments for PD.
