Abstract
BACKGROUND Extracorporeal shock wave lithotripsy represents one option for the non-surgical management of Peyronie's disease. Despite promising results, several questions are still pending. We want to present the long-term results of a retrospective study using high-energy extracorporeal shock wave lithotripsy. MATERIAL AND METHODS We evaluated retrospectively 110 patients treated between 1996 and 2020 at the Department of Urology, SLK Kliniken Heilbronn for chronic phase Peyronie's disease using two electromagnetic lithotripters (Siemens Lithostar Plus Overhead Module, Siemens Lithoskop) applying high-energy shock waves under local anesthesia and sonographic or fluoroscopic control. A standardized questionnaire focused on the change in pain, curvature, sexual function and the need of penile surgery. RESULTS In 85 of the 110 patients (mean age 54 years) we had sufficient data for evaluation. The median follow-up was 228 (6-288) months. There were no significant complications. Pain reduction was achieved in all patients, 65 (76%) patients were free of pain. Improvement of penile curvature was achieved in 43 patients (51%) ranging from 25% improvement (deflected angle < 30°) to 95% (angle 30-60°). 59 patients (69%) reported problems with sexual intercourse, 40 of those (68%) reported improvement. Only 9 (10.5%) patients underwent surgical correction. We did not observe any significant differences between both electromagnetic devices with stable long-term results. CONCLUSIONS High-energy shock wave therapy delivered by two standard electromagnetic lithotripters is safe and efficient providing stable long-term results. In cases with significant plaque formation, the concept of high-energy ESWT should be considered in future studies.

Abstract
BACKGROUND Peyronie's disease (PD) is associated with penile pain, deviation, and sexual dysfunction. Up till now, there is no conservative standard treatment for PD. However, the role of Extracorporeal Shock Wave Therapy (ESWT) is gaining increasing interest. AIM To evaluate the effect of ESWT on penile deviation, plaque size, erectile function, pain scale, and the rate of complications in PD patients. METHODS PubMed database was searched for articles published from January 2000 to November 2020, using related keywords and including randomized controlled trials (RCTs) only. Meta-analysis and forest plots were carried out using RevMan, and outcomes were reviewed by 2 authors independently. PRISMA guidelines were used in this article to achieve the quantitative and qualitative synthesis of data. OUTCOMES Changes in penile deviation, plaque size, erectile function, pain scale, and the rate of ESWT related complications. RESULTS The search yielded 73 articles. Three RCTs, including 117 patients in the ESWT group and 121 patients in the placebo group, were reviewed. ESWT is associated with reduction in plaque size (OR = 2.59, 95% CI (1.15-5.85), P= .02). No significant difference in reduction of penile deviation angle or rate of bruises were detected in post ESWT group when compared to placebo. No evidence was found to show an effect of ESWT on erectile function or pain scale. CLINICAL IMPLICATIONS Based on the available RCTs, ESWT fails to improve penile curvature or pain in men with PD. Although ESWT may reduce plaque size, this remains of questionable clinical significance. STRENGTHS & LIMITATIONS RCTs used different metrics to report the same outcome. Missed data were imputed to match the requirements of meta-analysis. However, there is still much data that cannot be estimated. CONCLUSION The current data suggest that ESWT fails to improve penile curvature or pain in men with PD. Although ESWT may reduce plaque size, this remains of questionable clinical significance, and further studies are required to confirm findings. Bakr AM, El-Sakka A.

Abstract
INTRODUCTION Although the literature of the positive effects of penile low intensity extracorporeal shockwave therapy is meanwhile substantial, there are substantial differences regarding both the sources of energies and extracorporeal shockwave therapy (ESWT) devices. OBJECTIVES To provide an overview on the energy range and energy differences of the 6 currently marketed ESWT devices along with personal ESWT experiences in 350 patients. METHODS This review includes all published preclinical and clinical penile ESWT studies with evaluation of the technical differences of the 6 ESWT devices and the personal experiences with these 6 devices in ED and PD. The main outcomes measures were success rates in ED (International Index of Erectile Function-erectile function change, conversion of phosphodiesterase type 5 inhibitors non-responders) and PD (change in deviation and plaque size), differences of used sources of energy, and energy flux densities (EFDs). RESULTS 3 different sources of energies are used, that is electromagnetic, electrohydraulic, and piezoelectric .The devices markedly distinguish in the available spectrum of the EFD ranging between 0.09 and 0.55 mJ/mm². In terms of the biological effects, the relevant energy parameters are -6 dB and the 5 MPa focus, which differ substantially between the ESWT devices. In addition, a great variability in the treatment protocols and applied energy is obvious. The preliminary own experiences with low intensity extracorporeal shockwave therapy in 160 ED non-responders and 190 patients with PD with success rates of 45% and 47%, respectively, are reported. CONCLUSION Positive results were published with all 6 ESWT devices in question in patients with organic ED but with huge differences regarding the EFD and the total energies applied. There is growing evidence that concentrated treatment protocols and increasing energies may yield better results. In this context, it may be argued that at least some of the published studies were markedly underpowered .Owing to the paucity of published studies, the literature of the effects of ESWT in PD and for penile rehabilitation after pelvic surgery is currently not conclusive.

Abstract
INTRODUCTION Despite recent advances in our knowledge and treatment strategies in Peyronie's Disease (PD), much remained unknown about this disease. AIM To provide a clinical framework and key guideline statements to assist clinicians in an evidence-based management of PD. METHODS A systematic literature search was conducted to identify published literature relevant to PD. The search included all relevant articles published up to June 2015, including preclinical studies and published guidelines. References used in the text were assessed according to their level of evidence, and guideline recommendations were graded based on the Oxford Centre for Evidence-Based Medicine Levels of Evidence. Owing to the paucity of larger series and randomized placebo-controlled trials with regard to surgical intervention, guideline statements are provided as clinical principle or expert opinion. MAIN OUTCOME MEASURES This literature was discussed at a panel meeting, and selected articles with the highest evidence available were used to create consensus guideline statements for the Fourth International Consultation on Sexual Medicine guidelines on PD. RESULTS In addition to existing Third International Consultation on Sexual Medicine guidelines on PD, seven new summary recommendations were created. CONCLUSION A greater understanding of the scientific basis of PD is greatly needed to address our understanding of the pathophysiology, clinical epidemiology, psychosocial, and diagnostic assessment as well as treatment strategies.

Abstract
Purpose To evaluate the efficacy, safety and patient satisfaction outcomes following low intensity extracorporeal shock wave therapy (LiESWT) in men with Peyronie's disease (PD) using a standardised protocol. Materials and Methods In this open-label single arm prospective study, patients with PD were enrolled following informed consent. Patient demographics, change in penile curvature and plaque hardness, International Index of Erectile Function (IIEF)-5 score, and overall satisfaction score (on a 5-point scale) were recorded. Treatment template consists of 3000 shock waves to the Peyronie's plaque over 20 minutes, twice weekly for 6 weeks. Results The majority of patients have PD history longer than 6 months (mean, 12.8 months; range, 6-28 months). Two thirds of patients have received and failed oral medical therapy. There were improvements in penile curvature (more than 15 degrees in 33% of men), plaque hardness (60% of men) and penile pain (4 out of 6 men) following LiESWT. There was a moderate improvement in IIEF-5 score (>5 points reported in 20% of men). No complication was reported and the majority of patients were satisfied (rated 4 out of 5; 70% of men) and would recommend this therapy to others. Conclusions In a carefully selected group of men with PD, LiESWT appears to be safe, has moderate efficacy and is associated with high patient satisfaction rate in the short term.

Abstract
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.

Abstract
BACKGROUND Extracorporeal shock wave therapy (ESWT) is a conservative therapy for patients with Peyronie's disease (PD). OBJECTIVE To investigate the effects of ESWT in patients with PD. DESIGN, SETTING, AND PARTICIPANTS One hundred patients with a history of PD not >12 mo who had not had previous PD-related treatments were enrolled in a prospective, randomized, double-blind, placebo-controlled study. Patients were randomly allocated to either ESWT (n=50) or placebo (n=50). Erectile function (EF), pain during erection, plaque size, penile curvature, and quality of life (QoL) were assessed at baseline, at 12 wk, and at 24 wk follow-up. INTERVENTION Four weekly treatment sessions were administered. Each ESWT session consisted of 2000 focused shock waves. For the placebo group, a nonfunctioning transducer was employed. MEASUREMENTS EF was evaluated with the shortened version of the International Index of Erectile Function (IIEF-5), pain was evaluated with a visual analog scale (VAS; 0-10), plaque size was measured in cm(2), and penile curvature was measured in degrees. RESULTS AND LIMITATIONS After 12 wk, mean VAS score, mean IIEF-5 score, and mean QoL score ameliorated significantly in patients receiving ESWT. Mean plaque size and mean curvature degree were unchanged in the ESWT group, while a slight increase was reported in the placebo group (p-value not significant vs baseline). After 24 wk, mean IIEF-5 score and mean QoL score were stable in the ESWT group, while mean VAS score was significantly lower when compared with baseline in both groups. Interestingly, after 24 wk, mean plaque size and mean curvature degree were significantly higher in the placebo group when compared with both baseline and ESWT values. The main limitations were that the QoL questionnaire was not validated, ED was not etiologically characterized, and inclusion criteria were restricted. CONCLUSIONS In patients with PD, ESWT leads to pain resolution and ameliorates both EF and QoL.

Abstract
IntroductionExtracorporeal Shock Wave Therapy (ESWT) is a minimal invasive treatment for patients with Peyronie's Disease (PD). Currently, however, controversial data exist on the efficacy of ESWT as first-line treatment.MethodsWe performed a prospective, randomized, double blind, placebo-controlled trial to evaluate the efficacy of ESWT in a group of 100 patients with disease duration <12 months, naive to previous treatments, with a single plaque, erectile dysfunction and/or painful erections and/or penile recurvatum. Patients were randomized to undergo ESWT or Placebo. The Storz Duolith device was employed for treatments. A non-functioning probe was employed as placebo. Treatments were administered in four sessions at weekly intervals. The following evaluations were performed at baseline and at 12- and 24-week intervals from treatment: IIEF-5 (International Index of Erectile Function) questionnaire, VAS (Visual Analogue Scale), plaque size measurement, penile curvature measurement.ResultsOnly patients treated with ESWT reported a significant improvement of mean VAS score and of mean IIEF-5 score at a 12-week follow-up. Mean plaque size and mean curvature degree did not improved significantly in patients treated with ESWT but showed a significant worsening at the 24-week follow up compared to baseline values in the placebo group.ConclusionsESWT can improve significantly painful erections and erectile functions in patients with PD naive to other treatments. Moreover, ESWT can stabilize plaque size and penile curvature thus preventing disease progression.

Abstract
OBJECTIVES Only minimal literature exists on consequences of shock wave therapy (SWT) on erectile function in treatment of Peyronie's disease (PD). This study was undertaken to define SWT impact at varied energy/dose levels at different time points on functional and structural changes in erectile tissue. METHODS In 45 rats 2000 shock waves (sw) at 2 BAR were applied to the penis weekly sorted by one, two, and three sessions (high-dose/energy level, HD-1, HD-2, HD-3). Each group was followed for 1, 7, or 28 d before measuring intracavernosal pressure (ICP) and mean arterial pressure (MAP). Fifteen control animals (C1, C7, C28) underwent anesthesia alone. Another 15 animals were exposed to three SWT sessions applying 1000 sw at 1 BAR and analyzed identically (low-dose/energy level, LD-3-1, -7, -28). Terminal deoxynucleotidyl transferase biotin-dUTP nick-end labeling assay was used to define the apoptotic index (AI) and Masson's trichrome (MT) staining was prepared to evaluate smooth muscle-to-collagen ratios. RESULTS ICP/MAP ratios for all C groups displayed a mean of 64%. All SWT groups demonstrated significantly reduced ICP/MAP ratios compared to their corresponding C groups (p<0.05). The LD-3 groups showed a trend toward improved ICP/MAP ratios. LD-3-28 demonstrated significant recovery compared to HD-3-28 (55+/-8% vs. 41+/-10%, p=0.004), but remained reduced compared to C28 (63+/-5%, p=0.03). No statistical differences were seen for MT staining in SWT groups compared to C (p>0.05). AIs for the LD-3 groups were significantly lower compared to the HD-3 groups (p<0.001), but all AIs were significantly increased compared to C groups (p<0.01). CONCLUSIONS Overall, at both energy/dose levels, SWT resulted in a time- and treatment-dependent reduction of ICP/MAP ratios, which might be mediated partly through apoptosis and collagenization of corporal smooth muscle.

Abstract
PURPOSE To analyze the long-term results in patients undergoing extracorporeal shockwave therapy (ESWT) for Peyronie's disease. PATIENTS AND METHODS Patients treated with ESWT (3000 shockwaves on a Storz Minilith SL lithotripter) for Peyronie's disease were included. The mean disease duration prior to treatment was 23.2 months (range 4-60 months). Penile angulation was measured before and after treatment by artificial vacuum induction of erection. Pain during erection was measured using a visual analog scale (VAS 0-5). The average number of ESWT sessions was 3.4 (range 2-9). The mean follow-up post-treatment was 44.1 months (range 42-48 months). Of 44 eligible patients, 38 patients (86.4%) were contactable for evaluation. RESULTS Of the 38 patients, 10 (26%) subsequently underwent corrective surgery for failed ESWT. Of the remaining 28 patients, 18 (47% of the total) had a statistically significant reduction in angulation, with a mean reduction of 33.2 degrees +/- 14.4 degrees (SD) (range 10 degrees -75 degrees ) (P < 0.001). Nine patients (24%) obtained no benefit, and one had an increase in angulation of 10 degrees . Of the 24 patients with pain, 16 (66.6%) reported relief after ESWT, the mean reduction being 2.5 (range 0.5-4.0) on the VAS (P < 0.001). Of the 28 patients who had not undergone surgical correction, 18 (65%) reported erections suitable for intercourse; 14 (48%) were satisfied with ESWT, 8 (30%) dissatisfied, and 6 (22%) uncertain. Although one patient complained of some penile shortening, no other long-term adverse events were noted. CONCLUSION Although a quarter of ESWT patients resorted to surgery, in the absence of other effective nonsurgical treatments, ESWT may provide a useful, safe, conservative management option. Extracorporeal shockwave therapy cannot yet be recommended as standard for Peyronie's disease, and randomized controlled studies are required to validate its efficacy and identify the subset of patients most likely to benefit.

Abstract
To evaluate whether extracorporeal shockwave therapy (ESWT) offers an effective treatment for the main complications of Peyronie's disease (PD), that is, penile deformity and angulation, painful erection and most importantly unsatisfied sexual intercourse. From September 1999 to January 2001, 52 patients with PD were treated with ESWT. Pain during erection was assessed with a visual analogue scale. Penile deviation was determined by photographs with a goniometer. Five treatment sessions were performed at weekly intervals. Each consisted of 3000 shockwaves with an emission frequency of 120 shockwaves/min and a mean intensity of 0.17 mJ/mm(2). A Storz Minilith SL 1 with integrated inline ultrasound probe was used. In all, 52 patients were evaluated 6 weeks after ESWT for early follow-up. Before ESWT intercourse was difficult or impossible for 40 men; 29 patients suffered mainly from penile deformity, 14 from painful erection and eight mainly from loss of distal rigidity. A total of 30 patients mentioned painful erection before treatment. In 28 patients (93%) pain reduction was achieved. A total relief of pain was observed in 19 patients (63%). Mean pain score dropped from 4.2 to 1.3 in patients who suffered predominantly from painful erections. Intercourse satisfaction improved in 11 patients after therapy. Mean angulation before (40 degrees ) and after (37 degrees ) ESWT did not change significantly. Late follow-up after 11.1 months (4-17 months) could be completed in 36 patients. In total, 19 men reported that ESWT improved their PD. Of these, 16 noted no change. Only one of the patients noticed a worsening of his disease during or after treatment. Complication rate was low with only minor side effects such as minimal skin bruising; one urethral bleeding occurred. ESWT did reduce pain during erection in patients suffering mainly from painful erection due to PD. However, penile angulation did not improve significantly in our setup and thus intercourse difficulties did improve only in 28% of the patients. Therefore, we do not recommend ESWT as a primary treatment for PD.

Abstract
PURPOSE Extracorporeal shock wave therapy (ESWT) for the treatment of Peyronie's disease is still controversial. This exploratory meta-analysis of published studies in the international literature investigates its therapeutic effects. MATERIALS AND METHODS The treatment outcomes from 17 study groups identified by a computerized literature search were compared with natural history outcomes and data from control groups from 2 controlled ESWT studies. An exploratory meta-analysis was performed because a methodologically sound meta-analysis lege artis did not appear appropriate, since treated groups differ considerably in structure, the selection of outcome measures is inconsistent and measurement is not standardized. RESULTS ESWT seems to have an effect on penile pain during erection and on the improvement of sexual function. Pain seems to resolve faster after ESWT than during the course of the natural history. The effect on plaque size and penile curvature is less impressive. CONCLUSIONS ESWT in Peyronie's disease at least seems to be effective in regard to penile pain and sexual function compared to natural history. Deducing from these data the effect on plaque size and curvature remains questionable. However, ESWT is not an evidence based therapy at present. A controlled (preferably pairwise matched), single blind, multicenter study with careful, detailed documentation of disease symptoms before intervention and of outcomes is required to evaluate the real effect of ESWT.

Abstract
PURPOSE Extracorporeal shock wave therapy (ESWT) for Peyronie's disease is still a topic of debate. We evaluated the effects of ESWT in a large series of patients with Peyronie's disease via a prospective approach. MATERIALS AND METHODS In a prospective study 114 patients with Peyronie's disease were treated with ESWT. Baseline and followup examinations included ultrasound, and measurement of plaque size and curvature. Symptomatology was evaluated based on a standardized interview. A Minilith SL1 (Storz Medical AG, Kreuzlingen, Switzerland) lithotriptor was used with 4,000 shock waves at a maximum energy level of 0.17 mJ/mm2 applied per session. RESULTS A total of 96 patients were available for followup. Considering the total study group no significant changes in penile curvature, plaque size or sexual function were observed despite significant improvements in patients with a curvature of 31 to 60 degrees. Penile pain ceased in 76% of the affected patients. CONCLUSIONS According to our data ESWT does not appear to be significantly effective for decreasing penile curvature and plaque size or improving sexual function in the total population of patients with Peyronie's disease despite improvements in individuals. Penile pain seems to resolve earlier than during the natural course. Regarding the results of this study and previous reports with exact documentation of the clinical findings it can be concluded that ESWT cannot be recommended as a standard procedure for Peyronie's disease. To evaluate the exact efficacy of ESWT a controlled, single-blind, multicenter study with exact documentation of symptoms is urgently required.

Abstract
Several drugs have been associated with an increased risk of erectile dysfunction (ED). We analysed the role of pharmacological treatments on the risk of ED using data from a cross-sectional study on prevalence and risk factors for ED in the general population in Italy. A total of 2450 men aged more than 18 years were randomly identified by 143 general practioners (GP) among their registered patients and invited to a confidential interview by their GP. Patients were asked 'about their ability to achieve and maintain an erection sufficient for satisfactory sexual performance'. If they were dissatisfied, they were defined as having ED. Out of the 2450 men identified, 440 (18%) refused to participate. The present analysis therefore includes information on 2010 men. After adjustment for related pathologies, anxiolytics and antidepressants showed insignificantly higher odds ratio (ORs, respectively, 1.7 and 2.1); antipsychotic drug use significantly increased the risk of ED (OR 9.0, 95% confidence interval, CI 1.8-44.4). Diuretics (OR 3.1, 95% CI 1.4-6.9) and anticholinergic drugs (OR 12.8, 95% CI 2.7-60.1) were associated with ED risk. No association emerged between ED and H2 antagonists, anticholesterolemic or hypoglycemic drugs. In conclusion, after taking account of related pathologies, our results suggest that men treated with antipsychotic, diuretic and anticholinergic drugs are at greater risk of ED.
