Abstract
To review the evidence of clinical efficacy of low-intensity extracorporeal shock wave therapy (Li-ESWT) for the treatment of erectile dysfunction (ED). A search on PubMed using Medical Subject Headings terms [((low intensity extracorporeal shockwave therapy) OR (Li-ESWT)) AND (erectile dysfunction)] was conducted in August 2022, to obtain studies on the use of Li-ESWT for the treatment of ED. Its success rate in terms of International Index of Erectile Function-5 (IIEF-5) score and Erection Hardness Score (EHS) improvement was recorded and analysed. A total of 139 articles were reviewed. Overall, 52 studies were included in the final review. 17 studies were on vasculogenic ED, 5 on post pelvic surgery ED, 4 specifically on ED in diabetic patients, 24 on non-specified origin ED and 2 on mixed pathophysiological origin ED. The mean age of patients was 55.87±7.91 (standard deviation) years and the duration of ED was 4.36±2.08 years. The mean IIEF-5 score went from 12.04±2.67 at baseline to 16.12±5.72, 16.30±3.26 and 16.85±1.63 respectively at 3, 6 and 12 months. The mean EHS went from 2.00±0.46 at baseline to 2.58±0.60, 2.75±0.46 and 2.87±0.16 respectively at 3, 6 and 12 months. Li-ESWT may be a safe and efficacy option for the treatment and cure of ED. Further studies are needed to assess which patients are more suitable for this procedure and which Li-ESWT protocol can lead to the best outcomes.

Abstract
OBJECTIVES To clarify the efficacy of low-intensity extracorporeal shockwave therapy for patients with erectile dysfunction, compare the efficacy between two types of lithotripters (ED1000 [focused type] and Renova [linear type]), and detect factors indicative of therapeutic gain with the treatment. METHODS This retrospective study included 76 patients (52.8 ± 11.7 years) treated by ED1000 (12 times over 9 weeks) and 484 patients (52.5 ± 11.6 years) treated by Renova (4 times over 4 weeks). Age, sexual symptoms scores, and blood examinations were assessed. Efficacy was judged by improvement of the scores and patient satisfaction and compared between patients at 1 month after treatment with the lithotripters. Independent factors influencing efficacy by Renova were also assessed. RESULTS Sexual symptom scores were improved significantly by both lithotripters, although the changes in the scores did not differ significantly between them. Efficacy rate as judged by patient satisfaction was 65.8% with the ED1000 and 71.1% with Renova, also without significant difference. Among several factors including age, sexual symptoms scores, endocrinological factors, metabolic factors, and the rate of phosphodiesterase type 5 inhibitor use, only age was found to be an independent factor influencing the efficacy of Renova. CONCLUSION We clearly showed the high efficacy of both lithotripters. Although the efficacy rate did not differ between them, we speculated that the fewer treatment sessions needed with the Renova versus the ED1000 would be a great advantage for patients. We also suggest that Renova should be recommended for patients younger than 70 years of age.

Abstract
Low-intensity extracorporeal shockwave therapy (LiESWT) represents a promising treatment for patients with erectile dysfunction (ED). We investigated the efficacy of LiESWT combined with tadalafil 5 mg once daily in men with type 2 diabetes mellitus (T2DM) and ED and compared LiESWT protocols administering different number of shockwaves. We performed a retrospective matched-pair comparison using data from a prospectively maintained database. Seventy-eight patients who received tadalafil 5 mg once daily for 12 weeks + LiESWT performed with an electrohydraulic source for 3 weeks (Group A) were matched 1:1 to patients who received tadalafil 5 mg once daily alone for 12 weeks (Group B). A subgroup analysis was performed according to the number of shockwaves delivered during each session (1500, 1800, and 2400 in subgroup A1, A2, and A3, respectively). The mean International Index of Erectile Function-5 (IIEF-5) score variations with respect to baseline recorded at 4, 12, and 24 weeks after the end of the treatment were investigated as treatment outcomes. The mean IIEF-5 scores significantly improved in all groups and subgroups at 4-week follow-up without intergroup differences. At 12- and 24-week follow-up, the mean IIEF-5 improvement was significantly higher among patients in the A3 subgroup (+5.0 ± 2.1 [P < 0.001] and +4.7 ± 2.3 [P < 0.001], respectively). The combined approach with tadalafil 5 mg once daily and LiESWT with a protocol involving 2400 shockwaves provides significant advantages in terms of IIEF-5 improvement and durability compared to tadalafil 5 mg once daily alone in patients with T2DM and ED.

[PMID: 33780173 DOI: 10.1111/andr.13007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 03/16/2021] [Accepted: 03/19/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Low-intensity extracorporeal shock wave therapy (ESWT) for the treatment of vasculogenic erectile dysfunction (ED) has emerged as a promising method directly targeting the underlying pathophysiology of the disease. OBJECTIVES To compare outcomes in ED patients after ESWT and placebo treatment. MATERIALS AND METHODS Prospective randomized placebo-controlled single-blinded trial on 66 patients with mild ED. The study comprised a 4-week washout phase, a 4-week treatment phase, and a 48-week follow-up. Inclusion criteria included age between 18 and 75 years and diagnosis of mild ED (IIEF-EF score = 17-25) being made at least six months prior to study inclusion and being confirmed by Penile Doppler ultrasonography (US) at baseline examination. Efficacy endpoints were changes from baseline in patient-reported outcomes of erectile function (International Index of Erectile Function domain scores [IIEF-EF]), as well as erection hardness and duration (Sexual Encounter Profile diary [SEP] and Global Assessment Questions [GAQ]). Safety was assessed throughout the study. RESULTS A total of 66 enrolled patients were allocated to ESWT (n = 44) or placebo (n = 22). Mean age of ESWT and placebo group was 42.32 ± 9.88 and 39.86 ± 11.64 (p = 0.374), respectively. Mean baseline IIEF-EF scores of ESWT group and placebo were 20.32 ± 2.32 and 19.68 ± 1.55 respectively (p = 0.34). At 3-months follow-up, mean IIEF-EF scores were significantly higher in ESWT patients than in placebo patients (23.10 ± 2.82 vs. 20.95 ± 2.19, p = 0.003), and IIEF-EF scores of ESWT patients remained high during the 6 months (22.67 ± 3.35 vs. 19.82 ± 1.56) follow-up. The percentage of patients reporting both successful penetration (SEP2) and intercourse (SEP3) in more than 50% of attempts was significantly higher in ESWT-treated patients than in placebo patients (p = 0.001). A minimal clinically important difference between the IIEF = EF baseline and 3-months follow-up was found in 74% of ESWT and 36% of placebo. No serious adverse events were reported. DISCUSSION AND CONCLUSION ESWT significantly improved the erectile function of relatively young patients with vasculogenic mild ED when compared to placebo and the beneficial effect of this treatment up to 6 months. These findings suggest that ESWT could be a useful treatment option in vasculogenic ED.

Abstract
Several methods of treatment of erectile dysfunction (ED) are offered with low energy shock-wave therapy (LESWT) gaining increasing attention. Reports have documented that LESWT stimulates tissue neovascularization, proliferation and differentiation of endothelial cells, and production of nitric oxide - all can improve the condition of erectile tissue. However, the overall and sexual condition of men deteriorates with age which is linked with a constant decrease in testosterone concentration. A higher risk of sexual health disorders and reduced physical fitness correlates with a testosterone concentration of <12 nmol/L. Such patients may require testosterone replacement therapy. We conducted a target literature review to investigate whether testosterone concentration is taken into account in studies on the use of LESWT in the treatment of ED. We found that most studies did not provide any information on testosterone status. Only 8 of 25 studies examined showed values of testosterone concentrations. Only one of these analyses checked the relationship between the efficacy of LESWT and testosterone concentration. As a result, meta-analyses published to date may not show the full value of LESWT in the treatment of ED. We conclude that in the light of the significant role testosterone plays in the process of an erection and the mechanism of LESWT action, it can be recommended to examine testosterone concentration and to diagnose hypogonadism during the qualification of patients to studies on LESWT efficacy. Moreover, the effectiveness of LESWT in relation to the current testosterone concentration should also be further investigated.

Abstract
The study aims to evaluate the effect of low-intensity extracorporeal shockwave therapy (Li-ESWT) on nocturnal erection and penile haemodynamics. Patients with erectile dysfunction (ED) were enrolled from January 2018 to March 2019. Self-reported erectile symptoms, the International Index of Erectile Function-5 (IIEF-5) and Erection Hardness Scores (EHS), nocturnal penile tumescence and rigidity (NPTR) and cavernous duplex Doppler ultrasound (CDDU) were evaluated. NPTR and CDDU were evaluated by Rigiscan and vascular ultrasound system respectively. Comparisons of NPTR and CDDU parameters were performed before and after Li-ESWT (Renova, once a week, 4 weeks in total). A total of 35 cases (mean age 36.51 ± 11.47 years) were enrolled for analysis. The IIEF-5 (10.60 ± 5.99 vs. 15.13 ± 6.22, p = .003), EHS (p = .016) and self-reported erectile hardness (p = .014) were significantly improved after 1-month treatment. Nocturnal erection frequency (p = .010), duration of total erection (p = .017), duration of erectile rigidity ≥60% at penile tip and base (p = .014 and p = .002) and the best erectile rigidity at penile tip and base (p = .012 and p = .005) improved significantly after treatment. However, no CDDU parameters improved after Li-ESWT (all p > .05). Li-ESWT can effectively improve subjective erectile function and nocturnal erection in ED patients. Large sample and well-designed studies need to be developed for supporting the current findings.

Abstract
OBJECTIVE To determine the effectiveness and safety in the short, medium, and long term of LISWT in patients with Erectile Dysfunction who do not respond to PDE5 inhibitors. METHODOLOGY Clinical study, quasi-experimental cohort and systematic review following the guidelines of the Cochrane collaboration and the PRISMA writing guides. The measurement of the variables was determined as a primary outcome to the evaluation of erectile function, by means of a validated questionnaire. The baseline scale was evaluated, as well as the difference at 1, 3 and 6 months, evidenced by the possibility of maintaining an erection or responding to therapy with PDEi5. An information search was carried out from its beginning to the current date, in the databases: Medline, Embase, Central, Science Direct and Lilacs. RESULTS The studies found used different outcome variables to show efficacy in the follow-up: All the studies used the IIEF-EF as outcome variable in its different variations. CONCLUSION LISWT could be an effective and safe treatment in patients not responding to PDEi5. It is important to point out that the evidence is currently limited, randomized studies with greater methodological rigidity and follow-up longer than 12 months are needed in order to verify the medium and long-term effect of the application of shock waves in this group of patients.

Abstract
Published literature shows low intensity extracorporeal shock wave therapy (LIESWT) and low intensity pulsed ultrasound (LIPUS) therapy to improve erectile function and penile hemodynamic by inducing neovascularisation and promoting tissue regeneration. Key opinion leaders across the Asia Pacific region attended the recent biennial meeting of the Asia Pacific Society for Sexual Medicine in Australia, and presented the current evidence on LIESWT and LIPUS for erectile dysfunction (ED). The clinical findings were internally discussed, and the quality of evidence was graded based on the Oxford Centre for Evidence-Based Medicine recommendations. Existing literature supports the use of LIESWT and LIPUS in men with ED, with many clinical studies reported encouraging results with improved erectile function, good safety profile and short-term durability. However, controversial exists due to sampling heterogeneity, non-standardised treatment protocol and lack of large multiinstitutional studies. There is a need to better define which subgroup of ED population is best-suited, and specific treatment protocol to optimise shock wave energy delivery. More stringent and larger multi-institutional randomised placebo-controlled trials are warranted before clinical adoption of LIESWT and LIPUS as the new standard of care for men with ED.

Abstract
PURPOSE To evaluate safety and clinical response of Low-intensity Shockwave Therapy (Li-SWT) for the treatment of erectile dysfunction. MATERIALS & METHODS A single-institution, 2 arm, phase II randomized clinical trial was conducted between February 2017 and April 2019. Patients were randomized into 2 groups, with Li-SWT delivering a total of 3,600 shocks over 5 days (720 once a day, Group A) or over 2 weeks (600 once a day, 3 times a week, Group B). Patients were evaluated for the safety of therapy and completed the International Index of Erectile Function-Erectile Function domain and the Erectile Hardness Scale assessment at baseline, and at 1, 3, and 6 months visits. RESULTS Among 87 evaluable patients, 45 and 42 were allocated to Groups A and B treatment schedules, respectively, and 80 patients (40 per group) completed the 6-month evaluation. No adverse events were reported during treatment or during follow-up. There were statistically significant (P < .05) improvements in International Index of Erectile Function-Erectile Function score (mean increase of 2.7 [95% CI = 1.2, 4.2] and 2.7 points [95% CI = 1.4, 4.1] for Groups A and B, respectively) and in Erectile Hardness Scale (mean increase of 0.6 points (95% CI = 0.3, 0.8) and 0.5 (95% CI = 0.2, 0.8) for Groups A and B, respectively) at 6 months, with no differences between groups. CONCLUSION No difference in outcomes was found when Li-SWT 3,600 shocks were delivered over 1 or 2 weeks at 6 months follow-up and both schedules were safe with no adverse events during or after treatment. Further trials with longer follow-up and sham arm will provide valuable information regarding treatment efficacy and durability. Patel P, Katz J, Lokeshwar SD, et al.

INTRODUCTION Low-intensity shockwave therapy (LISWT) has been investigated for the treatment of uroandrological disorders including erectile dysfunction (ED), Peyronie's disease (PD) and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) with controversial findings. AIM To review the evidence on LISWT for ED, PD, and CP/CPPS and provide clinical recommendations on behalf of the European Society of Sexual Medicine. METHODS Medline and Embase databases were searched for randomized clinical trials (RCTs), meta-analyses and open-label prospective or retrospective studies investigating the effect of LISWT on ED, PD, or CP/CPPS. OUTCOMES The panel provided statements on clinically relevant questions concerning LISWT: (i) treatment efficacy, (ii) treatment protocol, (iii) clinical indications, and (iv) safety. The level of evidence was provided according to the Oxford 2011 criteria and graded using the Oxford Centre for Evidence-Based Medicine recommendations. RESULTS 11 RCTs and 5 meta-analyses investigated LISWT for ED. RCTs provided controversial results on the efficacy of LISWT and were affected by high heterogeneity and the small number of patients included. Pooled-data analysis showed an overall positive effect in terms of erectile function improvement but reported small estimates and included a largely heterogeneous cohort of patients. 4 RCTs and 1 meta-analysis assessed LISWT for PD. All trials showed positive findings in terms of pain relief but no effect on penile curvature and plaque size. Inclusion criteria vary widely among studies, and further investigation is needed. 5 RCTs investigated LISWT for CP/CPPS. Data showed a possible effect on pain relief, although there is no evidence supporting that pain relief was maintained or any improvement in pain over time. CLINICAL IMPLICATIONS LISWT needs to be further investigated in the context of sexual medicine and is almost but not yet ready for clinical practice. STRENGTHS AND LIMITATIONS All studies have been evaluated by a panel of experts providing recommendations for clinical practice. CONCLUSIONS LISWT is a safe and well-tolerated procedure but its efficacy for the treatment of ED is doubtful and deserves more investigation. Patients reporting pain associated with PD may benefit from LISWT, although no effect is expected on disease progression. LISWT is not a primary treatment for CP/CPPS, but it may be considered as an option to relieve pain. Capogrosso P, Frey A, Jensen CFS, et al.

Determinants of Early Response to Low-Intensity Extracorporeal Shockwaves for the Treatment of Vasculogenic Erectile Dysfunction: An Open-Label, Prospective Study. J Clin Med 2019; 8:jcm8071017. [PMID: 31336717 PMCID: PMC6678562 DOI: 10.3390/jcm8071017] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2019] [Revised: 06/27/2019] [Accepted: 07/09/2019] [Indexed: 12/12/2022] Open
Abstract
The aim of this study was to expand existing literature on the effects of cardiovascular risk factors on the outcome of low-intensity extracorporeal shockwaves therapy (LIESWT), and to evaluate the role of hormone concentrations. Twenty patients with long-standing, PDE5i-resistant, vasculogenic erectile dysfunction (VED) were treated with six weekly sessions of LIESWT (9000 pulses). After a three-week break, four poor responders underwent another six weekly sessions. Rigidity score (RS) questionnaire was administered at baseline (T0), last session (T1), and three months after LIESWT (T2), while the Improvement component of the Clinical Global Impression of Change (CGIC-I) and the International Index of Erectile Function-5 (IIEF-5) questionnaires were administered at T1 and T2, and at T0 and T2, respectively. At T0 serum luteinizing hormone (LH), testosterone, sex hormone binding globulin (SHBG), calculated free testosterone, and prolactin levels were also recorded. At T1 and T2, 12/20 (60%) and 11/20 (55%) patients reached a RS ≥ 3; 16/20 (80%) and 13/20 (65%) improved their erections variably. Testosterone levels correlated positively with CGIC-I at T1. Patients < 65 years and those nonhypercholesterolemic had higher RS at T1 and T2. Age correlated negatively with RS at T1 and T2. At T0, diabetic patients had lower IIEF-5 scores, but those with RS ≥ 3 at T1 had higher IIEF-5 compared to those with RS < 3. Also, diabetes duration correlated inversely with IIEF-5 at T0. At T2, IIEF-5 improved significantly by an average of 2.8-points. We confirm safety and effectiveness of LIESWT for the treatment of VED. Age ≥ 65 years, diabetes, and hypercholesterolemia influence early and negatively the outcome of LIESWT.

Abstract
Introduction: Renal vasculature is extremely sensitive to vasoconstrictor effects of endothelin (ET), while nitric oxide (NO) has special role in several pathological renal conditions. Aim: The aim of this study to examine the presence, character, and degree of changes in NO and ET levels in the serum of extracorporeal shock wave lithotripsy (ESWL)-treated patients with nephrolithiasis. Patients and Methods: This study included a total of 60 patients that were divided in two groups: Group I (n = 24), in which a total of 2000SWs were administered; 0–2 units; (0.5 units per each 500SWs), and Group II (n = 36), in which a total of 4000SWs were administered; 0–4 units; (0.5 units per each 500SWs). Results: In the Group I median NO serum concentration increased in relation to pretreatment levels (39.04 ± 8.29 μmol/L) specifically 30 min, 60 min, and 24 h following the treatment (39.11 ± 12.60), (41.80 ± 6.89), and (46.33 ± 9.03), where concentration growth after 24 h was statistically significant P < 0.01. The NO serum concentration in the Group II increased in relation to pretreatment levels (38.90 ± 10.33 μmol/L) after 30 min (48.71 ± 30.09), 60 min (54.57 ± 39.76), and 24 h (97.95 ± 72.07). The NO concentration increase after 60 min and 24 h is statistically significant, respectively, P < 0.03 and P < 0.0001. Conclusion: NO and ET serum levels are changing under the influence of ESWL, and that the NO and ET changes are directly correlated with the number of administered shock waves and administered energy.

Abstract
Erectile dysfunction (ED) is defined as the inability to attain and maintain erection of the penis sufficient to permit satisfactory sexual activity. ED most commonly affects men from 40 years of age with a clear age-associated increase in prevalence. The condition may have significant negative impact on quality of life for both the patients and their partners. Over recent years, low-intensity shockwave therapy (LIST) has gained popularity in the treatment of ED, based on the assumption that LIST application may result in neoangiogenesis and thus increased blood flow to the corpora cavernosa. The increasing usage of LIST is contrasting with current guidelines, with the EAU guideline on ED stating that LIST can be used in mild organic ED patients or poor responders to PDE5I's, but with a weak strength of recommendation. In the AUA guideline on ED, the panel makes a conditional recommendation of grade C that LIST should be considered investigational. In this review, we will briefly review practice patterns, and critically discuss the evidence based on which these guideline statements have been made.

Abstract
The efficacy of low intensity extracorporeal shock wave therapy (LI-ESWT) for erectile dysfunction (ED) has received hard criticism and recently published meta-analyses were not able to provide further insights, nor specific recommendations. The aim of this systematic review and meta-analysis is to evaluate the efficacy of LI-ESWT for ED, identify the ideal treatment population and treatment protocol, and provide recommendations for future research in the field. A systematic research for relevant clinical studies published from January 2010 to September 2018 was performed, using the following databases: Medline, Embase, The Cochrane Library, Scopus, and Web of Science. Only clinical studies that investigated the efficacy of LI-ESWT for ED only, and reported primary outcomes using IIEF-EF scores/questionnaires were included. Both, randomised controlled trials (RCTs) and cohort studies were included, but the meta-analysis was performed only for sham-controlled RCTs. Ten RCTs including 873 patients were selected for the meta-analysis. Pooling data of these studies showed that LI-ESWT could significantly improve erectile function in men with ED regarding both patient-subjective outcomes (IIEF-EF: +3.97; 95% CI [2.09-5.84]; p < 0.0001, EHS ≥ 3: OR: 4.35; 95% CI [1.82-10.37]; p = 0.0009) and patient-objective outcomes (peak systolic velocity: +4.12; 95% CI [2.30-5.94]; p < 0.00001). In conclusion, the present meta-analysis provided results showing that LI-ESWT significantly improves erectile function in patients with vasculogenic ED.

Abstract
Managing patients with erectile dysfunction (ED) who failed to respond to phosphodiesterase type 5 inhibitors (PDE5is) is a challenging task. Recently, low-intensity extracorporeal shockwave therapy (LI-ESWT) was reported to improve ED by enhancing perfusion of the penis. The current study was performed to evaluate whether combined treatment with LI-ESWT and PDE5is can restore erectile function in patients who failed to respond to PDE5is alone. This was an open-label single-arm prospective study. ED patients with an erection hardness score (EHS) ≦2 under a maximal dosage of PDE5is were enrolled. Sociodemographic information and detailed medical history were recorded. LI-ESWT treatment consisted of 3,000 shockwaves once weekly for 12 weeks. All patients continued their regular PDE5is use. The EHS and the 5-item version of the International Index of Erectile Function (IIEF-5) were used to evaluate the change in erectile function 1 and 3 months after LI-ESWT. A total of 52 patients were enrolled. After LI-ESWT treatment, 35 of the 52 patients (67.3%) could achieve an erection hard enough for intercourse (EHS ≧ 3) under PDE5is use at the 1-month follow-up. Initial severity of ED was the only significant predictor of a successful response (EHS1: 35.7% vs. EHS2: 78.9%, p = .005). Thirty-three of the 35 (94.3%) subjects who responded to LI-ESWT could still maintain their erectile function at the 3-month follow-up. LI-ESWT can serve as a salvage therapy for ED patients who failed to respond to PDE5is. Initial severity of ED was an important predictor of a successful response.

Abstract
AIM The role of low-intensity extracorporeal shock wave therapy (LI-ESWT) in erectile dysfunction (ED) is not clearly determined. The purpose of this study is to investigate the short-term efficacy and safety of LI-ESWT for ED patients. MATERIALS AND METHODS Relevant studies were searched in Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), WANFANG and VIP databases. Effective rate in terms of International Index of Erectile Function-Erectile Function Domain (IIEF-EF) and Erectile Hardness Score (EHS) at about 1month after LI-ESWT was extracted from eligible studies for meta-analysis to calculate risk ratio (RR) of effective treatment in ED patients treated by LI-ESWT compared to those receiving sham-treatment. RESULTS Overall fifteen studies were included in the review, of which four randomized controlled trials (RCTs) were for meta-analysis. Effective treatment was 8.31 [95% confidence interval (CI): 3.88-17.78] times more effective in the LI-ESWT group (n=176) than in the sham-treatment group (n=101) at about 1 month after the intervention in terms of EHS, while it was 2.50 (95% CI: 0.74-8.45) times more in the treatment group (n=121) than in the control group (n=89) in terms of IIEF-EF. Nine-week protocol with energy density of 0.09mJ/mm2 and 1500 pluses seemed to have better therapeutic effect than five-week protocol. No significant adverse event was reported. CONCLUSION LI-ESWT, as a noninvasive treatment, has potential short-term therapeutic effect on patients with organic ED irrespective of sensitivity to PDE5is. Owing to the limited number and quality of the studies, more large-scale, well-designed and long-term follow-up time studies are needed to confirm our analysis.

Abstract
Erectile dysfunction (ED) is a common condition that significantly impacts a man’s physical and psychological well-being. ED is often associated with Peyronie’s disease (PD), which is an abnormal curvature of the penis. Delayed treatment of or surgical invention for PD often results in ED and therefore unsatisfied patients. The pathophysiology of PD is incompletely understood, but has been studied extensively and based on our current understanding of PD physiology, many medical treatment options have been proposed. In this paper, we will review what is known about the pathophysiology of PD and the medical treatment options that have been trialed as a result. More investigations in regards to the basic science of PD need to be carried out in order to elucidate the exact mechanisms of the fibrosis, and propose new, more successful treatment options which should be implemented prior to the onset of ED.

Abstract
Introduction Low-intensity shockwave therapy (LISWT) has recently emerged as a promising method in the treatment of erectile dysfunction (ED). Aim To assess the long-term results of the effectiveness and safety of LISWT in patients with ED who are non-responders to phosphodiesterase type 5 inhibitor (PDE5i) treatment. Methods This open-label, longitudinal, and observational study investigated an uncontrolled population of 50 consecutive patients whose ED was unresponsive to PDE5i treatment. Patients were treated with a four-session LISWT protocol. During active treatment and follow-up, all patients remained on their regular high on-demand or once-daily PDE5i dosing schedules. Main Outcome Measures Effectiveness was assessed according to the International Index of Erectile Function erectile function domain, questions 2 and 3 of the Sexual Encounter Profile, Erection Hardness Scale, and Global Assessment Question scores at baseline and at 3, 6, 9, and 12 months after treatment. Patients were considered responders whenever they showed improvement in erection parameters in all four assessments and responded positively to the Global Assessment Question. Adverse events were recorded. Statistical variables were applied and findings were considered statistically significant at a P value less than < .05. Results Eighty percent (mean age = 64.8 years) completed the 12-month follow-up. Positive response rates were 60% of available subjects at the end of the study and 48% of the intent-to-treat population. After the 12-month follow-up, 91.7% of responders maintained their responses. No patient reported treatment-related adverse events. Conclusion LISWT in patients with ED unresponsive to PDE5i treatment was effective and safe in 60% of patients treated. The efficacy response was maintained for 12 months in most patients.
