Indirect assessment of low-intensity shockwave therapy's energy density and pulse frequency for erectile dysfunction: a systematic review, bayesian network meta-analysis and meta-regression. Int J Impot Res 2024:10.1038/s41443-024-00910-w. [PMID: 38778153 DOI: 10.1038/s41443-024-00910-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 04/24/2024] [Accepted: 05/09/2024] [Indexed: 05/25/2024]
Abstract
Shockwaves are thought to activate regenerative and angiogenic pathways, providing a possible therapeutic benefit for patients with erectile dysfunction. This study aimed to analyze the effectiveness of low-intensity extracorporeal shockwave therapy energy density and pulse frequency. In May 2022, a systematic search of online databases was performed to identify randomized clinical trials related to low-intensity extracorporeal shockwave therapy in erectile dysfunction. Eligible articles compared low-intensity extracorporeal shockwave therapy to controls or sham procedures. A Bayesian framework with 200,000 Markov chains was performed. We included a total of 1272 patients from 18 studies. The energy flux density measured in joules included 0.09 mJ/mm2 (mean difference 3.2 IIEF [95% CrI 2.8, 3.6]), 0.15 mJ/mm2 (mean difference 4.9 IIEF [95% CrI 2.8, 7.2]) and 0.20 mJ/mm2 (mean difference 1.2 IIEF [95% CrI 0.11, 2.3]). Of these, 0.15 mJ/mm2 had the greatest ranking (SUCRA = 0.983) compared with placebo. When analyzed by pulse frequency, significant increases were found in 500 pulses/session (mean difference 2.5 IIEF [CrI 1.9, 3.2]), 1500 pulses/session (mean difference 4.6 IIEF [95% CrI 3.9, 5.4]) and > 3000 pulses/session (mean difference 3.1 IIEF [95% CrI 2.1, 4.2]). Of these, 1500 pulses/session had the highest SUCRA, at 0.996. Our network meta-analysis suggests that low-intensity extracorporeal shockwave therapy is an effective intervention for erectile dysfunction, as measured by increases in the IIEF-EF. Sessions featuring 1500 pulses and an energy flux density of 0.15 mJ/mm2 appear to be the most effective.

World J Mens Health 2024; 42:283-289.

Abstract
Low-intensity shockwave therapy (LiSWT) for erectile dysfunction (ED) continues to gain popularity in both clinical practice and the academic literature. The majority of trials and meta-analysis studies have shown LiSWT to be low risk with a trend toward positive improvements in International Index of Erectile Function (IIEF) scores. However, there is still debate over the clinical utility of LiSWT and there is no agreed upon optimal treatment protocol. In this review article we summarize published meta-analysis studies of LiSWT for ED, and review the treatment protocols from randomized sham-control trials published in the last 10 years. We found the most common device settings were an energy of 0.09 mJ/mm² and a frequency of 5 Hz. Shock number and location varied, but the most common protocol was 1,500 shocks per session, with 900 shocks to the penis (shaft, base, or hilum) and 600 shocks to the proximal corpora/crura. Protocols ranged from 4 to 12 treatment sessions. We also describe our institutional experience with LiSWT, including patient counseling and treatment protocol.

Abstract
This retrospective study assessed the efficacy of low-intensity extracorporeal shockwave therapy (Li-ESWT) in the treatment of erectile dysfunction (ED) in patients unresponsive to phosphodiesterase inhibitors (PDE5is). Between May 2020 and December 2022, we retrospectively analyzed the records of 126 ED patients who underwent Li-ESWT post unsuccessful PDE5is trials, defined as inadequate response following at least 6 consistent trials with correct dosage (preference given to 20 mg tadalafil). Patients with neurogenic disorders were excluded. Patients' ED severity was determined using the IIEF-5 score and further categorized into 2 groups. The Li-ESWT treatment protocol consisted of 12 weeks. Data was analyzed using descriptive statistics and paired t-tests. In the cohort of 126 patients, the mean age was 50.5 ± 12.4 years, with a BMI of 29.18 ± 3.49. Notably, 74.6% had ED for more than 12 months. Before Li-ESWT, 55.6% used sildenafil and 44.4% used tadalafil. Post 3 months of Li-ESWT, the average IIEF score rose significantly from 10.19 ± 7.71 to 14.29 ± 0.92 (P < .01). Particularly, Group 2 exhibited a significant improvement in their mean IIEF score from 13.78 ± 1.38 pretreatment to 21 ± 2.31 post-treatment. However, Group 1 (with higher diabetes prevalence) showed a marginal rise from 5.8 ± 1.47 to 6.1 ± 3.2 (P = .14). Similarly, the overall EHS score progressed significantly from 1.34 ± 0.8 to 2.3 ± 1.17 post-treatment. Post-treatment, while Group 1 showed no changes in successful vaginal penetration, Group 2 reported a dramatic increase in successes, from 16 before treatment to 68 after. This study demonstrated the efficacy of Li-ESWT for PDE5is-refractory ED, particularly in patients with moderate to mild ED. However, patients with severe ED and comorbidities did not show significant improvement. Further research with larger sample sizes, control groups, longer follow-up periods, and standardized protocols is required to confirm the effectiveness and limitations of Li-ESWT in ED treatment.

Abstract
Erectile dysfunction is a common sexual dysfunction that affects a significant proportion of men. Low-intensity extracorporeal shockwave therapy has been evaluated in multiple clinical trials as a therapeutic option for men with erectile dysfunction. The robustness of these clinical trials is not well defined, as the trials are hindered by inconsistent treatment protocols, small study arm size and short follow-up intervals. The fragility index is a statistical analysis which is used to evaluate the robustness of clinical trials. It is calculated by evaluating the minimum number of patients in a given trial arm that would be required to have an alternative outcome to alter the statistical significance of the results. The lowest fragility index in statistically significant trials is 1, meaning that if just one participant experienced an alternate outcome, the results would no longer achieve statistical significance. The upper limit is determined by the number of participants in a given arm of the trial. Herein, a scoping review of clinical trials evaluating the efficacy of low-intensity extracorporeal shockwave therapy in erectile dysfunction to determine the fragility index of trials with clinically significant results. We hypothesized that the fragility index would be low, indicating the results are less robust and generalizable.

[PMID: 37187905 PMCID: PMC10176068 DOI: 10.1016/j.heliyon.2023.e15778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 04/20/2023] [Accepted: 04/20/2023] [Indexed: 05/17/2023] Open
Abstract
Background Erectile dysfunction (ED) often affects men with type 2 diabetes mellitus (T2DM) due to microvascular damage. However, medical interventions are not always appropriate. Aim This scoping review aimed to answer the following question: What evidence is available about the effects of non-medical and non-invasive healthcare interventions to improve ED in men with T2DM? Method Potential studies were collected from the Cumulative Index to Nursing and Allied Health Literature via EBSCO, Embase via Ovid, MEDLINE via Ovid, Web of Science, PubMed, ProQuest, and PsycINFO via Ovid. Findings From 2,611 identified titles, 17 studies, including 11 interventional and 6 observational studies, were included. Four main alternatives to medical interventions were identified from the included studies. Amongst these, four studies recommended patient education on lifestyle modification, twelve studies encouraged dietary changes and physical activities, two studies emphasized the use of vacuum erectile device, and three studies suggested the application of low-intensity extracorporeal shockwave therapy by healthcare professionals. Discussion Dietary modification and physical activities were promoted as effective interventions to help maintaining the erectile function in men with T2DM. Several methods of patient education were identified as the approach to facilitate lifestyle modification in men with T2DM-associated ED. The positive outcomes of this review support early ED screening to help preventing T2DM complications such as ED in men. Further, T2DM management is a shared responsibility between the men and healthcare professionals. Despite the success of Vacuum Erectile Device and Low-intensity Extracorporeal Shockwave Therapy in regaining erectile function, further research is needed in this area based on the recommendations of the American Urological Association. Moreover, the health and quality of life of men with T2DM must be improved.

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
PURPOSE OF REVIEW This study aimed to review recent evidence on conservative non-surgical options for erectile dysfunction (ED) in men. A narrative review of the literature was performed. A comprehensive search in the MEDLINE, Embase, and Cochrane databases was done. Papers in English language, published from May 2017 until May 2022, were included. Papers reporting basic research or animal research were excluded, as long as reviews or meta-analyses. Congress reports, clinical cases, or clinical trials protocols with no results were also excluded. RECENT FINDINGS We found a multitude of different treatment modalities for ED. We must take into account the type of patient, their comorbidities, the origin of their ED, and its severity in order to reproduce effective results using these therapies. Some of the treatments show good results with a good level of evidence (new IPDE5 formulations, intracavernous injections, shock wave therapy, hormonal theraphy, psycho-sexual theraphy). However, others (some new molecules, stem cell theraphy, platelet-rich plasma injections, oxygenation-based therapy, nutraceuticals), although some of them present promising results, require randomized studies with a larger number of patients and a longer follow-up time to be able to establish firm recommendations. Regarding the conservative treatment of erectile dysfunction, in recent years, some therapies have been consolidated as effective and safe for certain types of patients. On the other hand, other treatment modalities, although promising, still lack the evidence and the necessary follow-up to be recommended in daily practice.

Abstract
BACKGROUND Erectile dysfunction (ED) is a very common complication in men with diabetes mellitus (DM). Low-intensity extracorporeal shockwave therapy (Li-ESWT) offers a promising nonsurgical treatment option for ED. A systematic scoping review investigating the outcomes of Li-ESWT in diabetic men with ED has not yet been performed. OBJECTIVES To systematically review animal and clinical studies related to the use of Li-ESWT for treatment of DM-related ED. DATA SOURCES PubMed, Embase, The Cochrane Library, Scopus, and Web of Science were searched, unrestricted by dates or study design. MATERIALS AND METHODS We included qualitative studies, quantitative studies, primary research studies, meta-analyses, and research letters written in English. Full text reviewing was completed in all animal and human studies discussing Li-ESWT for the treatment of ED in subjects with DM. Data extracted included the journal citation, publication year, country of origin, study design, and a summary of the pertinent findings. RESULTS Our search yielded nine clinical studies and 10 animal studies. The results of the clinical studies suggest that Li-ESWT is a safe and effective treatment in men with well-controlled DM and moderate or better ED. However, the benefit is less durable in diabetic men than nondiabetic men. The results of the animal studies suggest that Li-ESWT can significantly improve erectile function in diabetic rat models with ED. CONCLUSIONS The examined studies present encouraging results for the use of Li-ESWT to treat diabetic men with ED. Future studies, particularly robust randomized controlled trials, are necessary to confirm these findings and provide long-term follow-up.

Abstract
BACKGROUND The prevalence of diabetes mellitus-induced erectile dysfunction (DMED) has recently increased, which has prompted numerous DMED studies. Here, we conduct a bibliometric analysis of relevant literature in the field of DMED and to discuss the research hotspots and future development directions. METHODS The Web of Science Core Collection database was searched for literature on DMED, and literature characterization including the number of articles, journals, countries/regions, institutions, authors, keywords, and other information was performed using VOS viewer and CiteSpace software. In addition, Pajek software was used for visual map adjustment, and GraphPad Prism was used to generate line graphs. RESULTS A total of 804 articles concerning DMED were included in this study. The Journal of Sexual Medicine issued the most documents(92 articles). The United States and China were in the leading position in the field of DMED research, and cross-institutional collaboration on DMED research worldwide needs to be further strengthened. Ryu JK were the authors with the highest number of documents issued (22 articles) while Bivalacqua TJ was the author with the most co-citated(249 co-citated). The keywords analysis shows that the main research hotspots in the field of DMED were mechanism discussions and disease treatment and management. CONCLUSIONS Global research on DMED is expected to increase further. The investigation of the mechanism of DMED and the exploration of new therapeutic means and targets are the focus of future research.

Abstract
Diabetic foot ulcers (DFUs) are characterized by a lack of angiogenesis and distal limb diabetic neuropathy. This makes it possible for opportunistic pathogens to protect the biofilm-encased micro-communities, causing a delay in wound healing. The acute and chronic phases of DFU-associated infections are distinguished by the differential expression of innate proinflammatory cytokines and tumor necrosis factors (TNF-α and -β). Efforts are being made to reduce the microbial bioburden of wounds by using therapies such as debridement, hyperbaric oxygen therapy, shock wave therapy, and empirical antibiotic treatment. However, the constant evolution of pathogens limits the effectiveness of these therapies. In the wound-healing process, continuous homeostasis and remodeling processes by commensal microbes undoubtedly provide a protective barrier against diverse pathogens. Among commensal microbes, probiotics are beneficial microbes that should be administered orally or topically to regulate gut-skin interaction and to activate inflammation and proinflammatory cytokine production. The goal of this review is to bridge the gap between the role of probiotics in managing the innate immune response and the function of proinflammatory mediators in diabetic wound healing. We also highlight probiotic encapsulation or nanoformulations with prebiotics and extracellular vesicles (EVs) as innovative ways to tackle target DFUs.

Abstract
A shock wave (SW), which carries energy and propagates through a medium, is a type of continuous transmitted sonic wave that can achieve rapid energy transformations. SWs have been applied for many fields of medical science in various treatment settings. In urology, high-energy extracorporeal SWs have been used to disintegrate urolithiasis for 30 years. However, at lower energy levels, SWs enhance the expression of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), proliferating cell nuclear antigen (PCNA), chemoattractant factors, and the recruitment of progenitor cells, and inhibit inflammatory molecules. Low energy extracorporeal shock wave (LESW) therapy has been used in urology for treating chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), interstitial cystitis/bladder pain syndrome (IC/BPS), overactive bladder, stress urinary incontinence, and erectile dysfunction through the mechanisms of anti-inflammation, neovascularization, and tissue regeneration. Additionally, LESW have been proven to temporarily increase tissue permeability and facilitate intravesical botulinum toxin delivery for treating overactive bladders in animal studies and in a human clinical trial. LESW assisted drug delivery was also suggested to have a synergistic effect in combination with cisplatin to improve the anti-cancer effect for treating urothelial cancer in an in vitro and in vivo study. LESW assisted drug delivery in uro-oncology is an interesting suggestion, but no comprehensive clinical trials have been conducted as of yet. Taken together, LESW is a promising method for the treatment of various diseases in urology. However, further investigation with a large scale of clinical studies is necessary to confirm the real role of LESW in clinical use. This article provides information on the basics of SW physics, mechanisms of action on biological systems, and new frontiers of SW medicine in urology.

Systematic Review and Meta-Analysis of 16 Randomized Controlled Trials of Clinical Outcomes of Low-Intensity Extracorporeal Shock Wave Therapy in Treating Erectile Dysfunction. Am J Mens Health 2022; 16:15579883221087532. [PMID: 35319291 PMCID: PMC8949743 DOI: 10.1177/15579883221087532] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 01/23/2022] [Accepted: 02/25/2022] [Indexed: 12/29/2022] Open
Abstract
We conducted a meta-analysis to evaluate the efficacy of low-intensity extracorporeal shock wave therapy (LI-ESWT) in the treatment of erectile dysfunction (ED). From July 2011 to June 2021, we finally selected 16 randomized controlled trials (RCTs) including 1,064 participants to evaluate the efficacy of LI-ESWT in the treatment of ED from PubMed, EMBASE, and Cochrane databases. The data are analyzed by Review Manager Version 5.4. Fifteen articles mentioned International Index of Erectile Function (IIEF), in the follow-up of 1 month (mean difference [MD] = 3.18, 95% confidence interval [CI] = [1.38, 4.98], p = .0005), 3 months (MD = 3.01, 95% CI = [2.04, 3.98], p < .00001), and 6 months (MD = 3.20, 95% CI = [2.49, 3.92], p < .00001). After treatment, the improvement of IIEF in the LI-ESWT group was better than that in the control group. Besides, eight of the 16 trials provided data on the proportion of patients with baseline Erectile Hardness Score (EHS) ≤ 2 improved to EHS ≥ 3. The LI-ESWT group was also significantly better than the placebo group (odds ratio [OR] = 5.07, 95% CI = [1.78, 14.44], p = .002). The positive response rate of Questions 2 and 3 of the Sexual Encounter Profile (SEP) was not statistically significant (SEP2: OR = 1.27, 95% CI = [0.70, 2.30], p = .43; SEP3: OR = 4.24, 95% CI = [0.67, 26.83], p = .13). The results of this meta-analysis suggest that treatment plans with an energy density of 0.09 mJ/mm2 and pulses number of 1,500 to 2,000 are more beneficial to IIEF in ED patients. In addition, IIEF improvement was more pronounced in patients with moderate ED after extracorporeal shockwave therapy.

The Efficacy of Li-ESWT Combined With VED in Diabetic ED Patients Unresponsive to PDE5is: A Single-Center, Randomized Clinical Trial. Front Endocrinol (Lausanne) 2022; 13:937958. [PMID: 35813628 PMCID: PMC9259797 DOI: 10.3389/fendo.2022.937958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 05/23/2022] [Indexed: 11/17/2022] Open
Abstract
INTRODUCTION Phosphodiesterase type 5-inhibitors (PDE5is) are the first-line treatment for patients with diabetes mellitus-induced erectile dysfunction (DMED), however, some patients are non-responser to PDE5is. We performed a perspective, randomized, comparative study to explore the efficacy of low intensity extracorporeal shock wave treatment (Li-ESWT) combined with vacuum erectile device (VED) in the treatment of DMED patients who were unresponsive to PDE5is. METHODS One hundred and five eligible patients were randomly divided into three groups: group A (VED), group B (Li-ESWT) and group C (VED plus Li-ESWT). Follow-up was conducted at 4 weeks, 8 weeks and 12 weeks after the end of treatment. The erectile function was estimated by the international index of erectile function-erectile function domain (IIEF-EF), erection hardness score (EHS), sexual encounter profile questions 2 and 3 (SEP2 and SEP3) and global assessment question 1 and 2 (GAQ1 and GAQ2) before and after treatment. The changes of five points in IIEF-EF were calculated as the minimal clinical important difference (MCID), which was considered as the main index of efficacy. RESULTS The MCID was achieved in 14.7%, 14.7% and 17.6% patients in group A at the follow up on 4 weeks, 8 weeks and 12 weeks, respectively (36.4%, 39.4% and 36.4% in group B; 36.4%, 51.5%, and 66.7% in group C). There were significant differences in the percentage of MCID cases between group A and group C at the follow up on 12 weeks (P<0.001), as well as that between group B and group C (P=0.014). Additionally, comparison in MCID within group C showed that there were significant differences between 4 weeks and 12 weeks follow-up (P=0.014). CONCLUSION Our findings indicated the combined therapy Li-ESWT and VED was more beneficial to shift turn PDE5is non-responders to responders for moderate patients with DMED than VED or Li-ESWT monotherapy. Moreover, this study provided evidence that patients with DMED who failed after taking oral PDE5is could attempt to opt for an alternative physicotherapy (Li-ESWT or VED) prior to more invasive alternatives.
