Kalyvianakis D, Mykoniatis I, Pyrgidis N, Kapoteli P, Zilotis F, Hatzichristou D. The effect of combination treatment with low-intensity shockwave therapy and daily tadalafil on severe erectile dysfunction: a double-blind, randomized, sham-controlled clinical trial. J Sex Med 2024; 21:533-538. [PMID: 38600694 DOI: 10.1093/jsxmed/qdae038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 02/19/2024] [Accepted: 02/25/2024] [Indexed: 04/12/2024]
Abstract
BACKGROUND Patients with severe erectile dysfunction (ED) remain the most challenging group in terms of available noninvasive treatment modalities. AIM The study sought to assess the role of combination therapy with low-intensity shockwave therapy (LiST) and daily tadalafil 5 mg in a highly select group of patients with severe vasculogenic ED through a double-blind, randomized trial. METHODS Forty-eight sexually active men were randomly assigned to 12 sessions of LiST 3 times weekly and tadalafil 5 mg once daily (n = 34) or sham therapy and tadalafil (n = 17) for 4 weeks. Patients were assessed at 1 and 3 months after completion of treatment. OUTCOMES Improvement of erectile function was evaluated through the International Index of Erectile Function-Erectile Function domain (IIEF-EF) or 6-item IIEF and the Sexual Encounter Profile (SEP) diary. The primary outcome was the difference between the groups in the IIEF-EF at 3 months after completion of treatment. Secondary outcomes comprised (1) the difference between the groups in the IIEF-EF at 1 month after completion of treatment, (2) the difference between the groups in the "yes" responses to question 3 of the SEP diary at 1 and 3 months, and (3) the treatment-related adverse events. The number of patients attaining a minimal clinically important difference in the IIEF-EF (improvement of at least 7 points) was also assessed. RESULTS After treatment, the absolute scores in the IIEF-EF were higher in patients receiving LiST and tadalafil vs sham therapy and tadalafil both at the 1-month (12.1 ± 2.4 vs 10.2 ± 1.7; P = .002) and at the 3-month (12.9 ± 2.1 vs 10.8 ± 1.8; P < .001) evaluation. Between the 2 groups, the proportion of "yes" responses to question 3 of the SEP diary was not statistically significant, whereas the number of patients attaining a minimal clinically important difference in the IIEF-EF was statistically significant only at the 3-month evaluation. No adverse events occurred. CLINICAL IMPLICATIONS Application of LiST in patients with severe vasculogenic ED receiving daily dose tadalafil may further improve erectile function compared with tadalafil as a stand-alone treatment on the short term. STRENGTHS AND LIMITATIONS Although we provided the first study in the field, severe vasculogenic ED was defined based on medical history and clinical examination and not based on penile ultrasound measures. CONCLUSION The combination of 12 sessions LiST 3 times weekly and daily tadalafil for 4 weeks led to a 2-point difference in the IIEF-EF compared with sham therapy and daily tadalafil among patients with severe vasculogenic ED after 1 and 3 months from completion of treatment.

Abstract
BACKGROUND Erectile dysfunction (ED) is a condition that affects many males. Physical therapy (PT) is the one potential treatment for ED that may improve blood flow, muscle strength, and other factors that may contribute to the issue. Data on the prevalence and trends of research on PT for ED are lacking. OBJECTIVE This study aimed to evaluate the literature trends in PT for ED via bibliometric and visualized analysis. METHODS Data on publications were collected from Scopus covering the period between 1989 and 2022. To refine the data, bibliometric analyses were conducted using Microsoft Access, Microsoft Excel, an online visualization platform, and BiblioAnalytics. Power BI and Bibliomaster were used to generate figures and tables, while Biblioshiny and VOSviewer were used for visualization. RESULTS A total of 494 documents were identified. The year 2019 generated the largest number of publications, with a total of 54. These studies have received 12,917 citations related to PT for ED. The most common document type was the original article with 283 publications. The University of California, USA, was the most productive institution on this topic, with 21 publications and 2,035 citations. The USA led all countries with 114 publications on the topic. The Journal of Sexual Medicine secured the top ranking with an h-index of 18. The main topics studied were erectile dysfunction, shockwave therapy, and physiotherapy. CONCLUSION The number of publications on PT for ED has demonstrated an upward trend over the last three decades.

Abstract
Cellular behavior is regulated by mechanical signals within the cellular microenvironment. Additionally, changes of temperature, blood flow, and muscle contraction also affect cellular state and the development of diseases. In clinical practice, physical therapy techniques such as ultrasound, vibration, exercise, cold therapy, and hyperthermia are commonly employed to alleviate pain and treat diseases. However, the molecular mechanism about how these physiotherapy methods stimulate local tissues and control gene expression remains unknow. Fortunately, the discovery of YAP filled this gap, which has been reported has the ability to sense and convert a wide variety of mechanical signals into cell-specific programs for transcription, thereby offering a fresh perspective on the mechanisms by which physiotherapy treat different diseases. This review examines the involvement of Hippo/YAP signaling pathway in various diseases and its role in different physical therapy approaches on diseases. Furthermore, we explore the potential therapeutic implications of the Hippo/YAP signaling pathway and address the limitations and controversies surrounding its application in physiotherapy.

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.

Effectiveness of Low-Intensity Extracorporeal Shock Wave Therapy in Erectile Dysfunction: An Analysis of Sexual Function and Penile Hardness at Erection: An Umbrella Review. J Pers Med 2024; 14:177. [PMID: 38392610 PMCID: PMC10890328 DOI: 10.3390/jpm14020177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 01/10/2024] [Accepted: 01/29/2024] [Indexed: 02/24/2024] Open
Abstract
The present umbrella review of five systematic reviews and meta-analyses was conducted to investigate the effectiveness of Low-Intensity Extracorporeal Shock Wave Therapy (Li-ESWT) in the treatment of vascular origin Erectile Dysfunction (ED). A search was carried out in the databases of Pubmed, Scopus, Medline, Scielo and Embase. Participants were divided into two groups: an experimental group receiving Li-ESWT and a control group receiving simulated shock waves. The main variable of this study is ED, measured using the International Index of Erectile Function-Erectile Function (IIEF-EF) and the Erection Hardness Score (EHS) scale. The results showed a statistically significant increase in the mean IIEF-EF score in the experimental group. Overall, four out of five articles reported an increase in the EHS score in the Li-ESWT group compared to the placebo. Concerning the treatment parameters, better outcomes were observed with an energy density of 0.09 mJ/mm2 and the application of 1500-2000 pulses. Additionally, a follow-up of 6-12 months resulted in greater improvement in ED compared to 3 months, although more studies investigating follow-ups beyond 12 months are needed. Obtaining conclusive and clear results is challenging; however, everything indicates that Li-ESWT is an innovative therapeutic alternative for vascular-origin ED due to its low risk and improvement in erectile function.

Extracorporeal Shockwave Therapy Alleviates Inflammatory Pain by Down-Regulating NLRP3 Inflammasome in Experimental Chronic Prostatitis and Chronic Pelvic Pain Syndrome. World J Mens Health 2024; 42:157-167. [PMID: 37382279 PMCID: PMC10782125 DOI: 10.5534/wjmh.220241] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Revised: 01/15/2023] [Accepted: 02/06/2023] [Indexed: 06/30/2023] Open
Abstract
PURPOSE To evaluate the anti-inflammatory and antioxidative effects of extracorporeal shockwave therapy (ESWT) on prostatitis and explore the mechanism of alleviating pain. MATERIALS AND METHODS For in vitro testing, RWPE-1 cells were randomly divided into 5 groups: (1) RWPE-1 group (normal control), (2) LPS group (lipopolysaccharide inducing inflammation), (3) 0.1ESWT group (treated by 0.1 mJ/mm² energy level), (4) 0.2ESWT group (treated by 0.2 mJ/mm² energy level), and (5) 0.3ESWT group (treated by 0.3 mJ/mm² energy level). After ESWT was administered, cells and supernatant were collected for ELISA and western blot. For in vivo testing, Sprague-Dawley male rats were randomly divided into 3 groups: (1) normal group, (2) prostatitis group, and (3) ESWT group (n=12 for each). Prostatitis was induced by 17 beta-estradiol and dihydrotestosterone (DHT) administration. Four weeks after ESWT, the pain index was assessed for all groups and prostate tissues were collected for immunohistochemistry, immunofluorescence, apoptosis analysis and, western blot. RESULTS Our in vitro studies showed that the optimal energy flux density of ESWT was 0.2 mJ/mm². In vivo, ESWT ameliorated discomfort in rats with prostatitis and inflammation symptoms were improved. Compared to normal rats, overexpressed NLRP3 inflammasomes triggered apoptosis in rats with prostatitis and this was improved by ESWT. TLR4-NFκB pathway was overactive after experimental prostatitis, compared to normal and ESWT groups, and prostatitis induced alterations in BAX/BAK pathway were inhibited by ESWT. CONCLUSIONS ESWT improved CP/CPPS by reducing NLRP3 inflammasome and ameliorated apoptosis via inhibiting BAX/BAK pathway in a rat model. TLR4 may play a key role in bonding NLRP3 inflammasome and BAX/BAK pathways. ESWT might be a promising approach for the treatment of CP/CPPS.

Abstract
The significant discontinuation rate of available therapies and the paucity of curative options promoted the research on potential novel treatments suitable for erectile dysfunction patients. The aim of this study was to provide a summary of available evidence regarding the news and future perspectives related to the non-surgical treatment of erectile dysfunction. A narrative review of the literature was performed. A comprehensive search in the MEDLINE, Embase, and Scopus databases was done. Papers in English-language, published until April 2022, were included. No chronological restriction was applied. Retrospective and prospective clinical studies, as well as meta-analyses, were considered. Oro-dispersible formulations of phosphodiesterase type 5 inhibitors are particularly indicated in patients who have difficulty in swallowing solid dosage form; in addition, they constitute a discrete route of administration not requiring water. Low-intensity extracorporeal shock wave therapy is indicated in mild vasculogenic erectile dysfunction and in patients with vasculogenic erectile dysfunction poorly responsive to phosphodiesterase type 5 inhibitors. Stem cell therapy, platelet-rich plasma injections, and gene therapy seem promising regenerative treatments for selected patients with erectile dysfunction. Novel oral formulations of drugs commonly used in erectile dysfunction patients have recently become part of standard clinical practice. Regenerative treatments have been emerging in recent years and could become routine curative options in the near future. Further well-designed randomized controlled trials are needed to provide conclusive evidence on this topic and guide appropriate recommendations.

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.

Andrology 2023; 11:1472-1483. [PMID: 36869699 DOI: 10.1111/andr.13422] [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: 11/10/2022] [Revised: 02/20/2023] [Accepted: 02/24/2023] [Indexed: 03/05/2023]
Abstract
BACKGROUND Diabetes mellitus-induced erectile dysfunction is difficult to treat. The oxidative stress created by diabetes mellitus is a major cause of injuries to the corpus cavernosum, thereby resulting in erectile dysfunction. Near-infrared laser has already been shown to be effective in treating multiple brain disorders because of its antioxidative stress effect. OBJECTIVES To investigate whether a near-infrared laser improves the erectile function of diabetes mellitus-induced erectile dysfunction rats through its antioxidative stress effect. MATERIALS AND METHODS Knowing its advantage of reasonable deep tissue penetration and good photoactivation on mitochondria, a near-infrared laser with wavelength of 808 nm was used in the experiment. Since the internal and external corpus cavernosum were covered by different tissue layers, the laser penetration rates of the internal and external corpus cavernosum were measured separately. Different radiant exposure settings were applied: in the initial experiment, 40 male Sprague-Dawley rats were randomly assigned to five groups, normal controls, and streptozotocin-induced diabetes mellitus rats that 10 weeks later received various radiant exposures (J/cm2 ) from the near-infrared laser (DM0J(DM+NIR 0 J/cm2 ), DM1J, DM2J, and DM4J) in the subsequent 2 weeks. Erectile function was then assessed 1 week after near-infrared treatment. It was found that the initial radiant exposure setting was not optimal according to the Arndt-Schulz rule. We performed a second experiment using a different radiant exposure setting. Forty male rats were randomly divided into five groups (normal controls, DM0J, DM4J, DM8J, and DM16J), and the near-infrared laser was again applied according to the new setting, and erectile function was assessed as in the first experiment. Histologic, biochemical, and proteomic analyses were then conducted. RESULTS Recovery of erectile function of varying degrees was observed in the near-infrared treatment groups, and radiant exposure of 4 J/cm2 achieved optimal results. The DM4J group showed improvement in mitochondrial function and morphology in diabetes mellitus rats, and it was found that oxidative stress levels were significantly reduced by near-infrared exposure. The tissue structure of the corpus cavernosum was also improved by near-infrared exposure. The proteomics analysis confirming multiple biologic processes were changed by diabetes mellitus and near-infrared. DISCUSSION AND CONCLUSION Near-infrared laser activated mitochondria, improved oxidative stress, repaired the damage to penile corpus cavernosum tissue structures caused by diabetes mellitus, and improved erectile function in diabetes mellitus rats. These results thus raise the possibility that human patients with diabetes mellitus-induced erectile dysfunction may respond to near-infrared therapy in a manner that parallels the responses we observed in animal study.

[PMID: 37644168 DOI: 10.1038/s41443-023-00757-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 08/11/2023] [Accepted: 08/17/2023] [Indexed: 08/31/2023]
Abstract
This study retrospectively examined the effects of low-intensity extracorporeal shockwave therapy and tadalafil on erectile dysfunction patients. 116 patients got low-intensity extracorporeal shockwave therapy twice weekly for 3 weeks, 5 mg of tadalafil daily for 3 weeks, and adjuvant therapy for 6 months. Group A (1 year), Group B (2 years), Group C (3 years), and Group D (4+ years) were treated patients' follow-up groups. The patients' International Index of Erectile Function-5 (IIEF-5) scores were gathered at the start of treatment via face-to-face interviews and at the end of follow-ups by telephone conversations. IIEF-5 scores and the minimal clinically significant differences were the main outcomes. Mean follow-up length, age, and IIEF-5 scores of the patients were 2 ± 1.16 years, 47.34 ± 12.65 years, and 12.09 ± 3.66 points, respectively. Compared to baseline, treatment increased the median IIEF-5 scores of patients in groups A, B, C, and D by 7 [3-12], 6 [0-8], 7 [1-9], and 6.5 [2.5-10] points, respectively (p = 0.001). 71%, 63%, 65.8%, and 65% of treated patients in groups A, B, C, and D met the minimal clinically significant differences criteria (n = 77). Mild disease patients were 9.14 times more likely to respond to treatment than severe illness patients (OR, 9.14; 95% CI, 1.28-65.46; P = 0.02). Low-intensity extracorporeal shockwave therapy and 5 mg of tadalafil can treat erectile dysfunction for up to 4 years with sustained outcomes. This treatment is optimal for mild illnesses.

Abstract
Erectile dysfunction (ED) is the most common sexual dysfunction disease in adult males. ED can be caused by many factors, such as vascular disease, neuropathy, metabolic disturbances, psychosocial causes, and side effects of medications. Although current oral phosphodiesterase type 5 inhibitors can achieve a certain effect, they cause temporary dilatation of blood vessels with no curative treatment effects. Emerging targeted technologies, such as stem cell therapy, protein therapy, and low-intensity extracorporeal shock wave therapy (Li-ESWT), are being used to achieve more natural and long-lasting effects in treating ED. However, the development and application of these therapeutic methods are still in their infancy, and their pharmacological pathways and specific mechanisms have not been fully discovered. This article reviews the preclinical basic research progress of stem cells, proteins, and Li-ESWT therapy, as well as the current status of clinical application of Li-ESWT therapy.

Abstract
OBJECTIVES To provide an overview of low-intensity extracorporeal shockwave therapy (LIEST) for erectile dysfunction (ED), pointing out which concepts are already consolidated and which paths we still need to advance. MATERIALS AND METHODS We performed a narrative review of the literature on the role of shockwave therapies in erectile dysfunction, selecting publications in PUBMED, including only relevant clinical trials, systematic reviews and meta-analyses. RESULTS We found 11 studies (7 clinical trials, 3 systematic review and 1 meta-analysis) that evaluated the use of LIEST for the treatment of erectile dysfunction. One clinical trial evaluated the applicability in Peyronie's Disease and one other clinical trial evaluated the applicability after radical prostatectomy. CONCLUSIONS The literature presents little scientific evidence but suggests good results with the use of LIEST for ED. Despite a real optimism since it is a treatment modality capable of acting on the pathophysiology of ED, we must remain cautious, until a larger volume of higher quality studies allows us to establish which patient profile, type of energy and application protocol will achieve clinically satisfactory results.

Abstract
Phosphodiesterase type 5 inhibitors (PDE5is) constitute the primary therapeutic option for treating erectile dysfunction (ED). Nevertheless, a substantial proportion of patients, approximately 30%, do not respond to PDE5i treatment. Therefore, new treatment methods are needed. In this study, we identified a pathway that contributes to male erectile function. We show that mechano-regulated YAP/TAZ signaling in smooth muscle cells (SMCs) upregulates adrenomedullin transcription, which relaxed the SMCs to maintain erection. Using single-nucleus RNA sequencing, we investigated how penile erection stretches the SMCs, inducing YAP/TAZ activity. Subsequently, we demonstrate that YAP/TAZ plays a role in erectile function and penile rehabilitation, using genetic lesions and various animal models. This mechanism relies on direct transcriptional regulation of adrenomedullin by YAP/TAZ, which in turn modulates penile smooth muscle contraction. Importantly, conventional PDE5i, which targets NO-cGMP signaling, does not promote erectile function in YAP/TAZ-deficient ED model mice. In contrast, by activating the YAP/TAZ-adrenomedullin cascade, mechanostimulation improves erectile function in PDE5i nonrespondent ED model rats and mice. Furthermore, using clinical retrospective observational data, we found that mechanostimulation significantly promotes erectile function in patients irrespective of PDE5i use. Our studies lay the groundwork for exploring the mechano-YAP/TAZ-adrenomedullin axis as a potential target in the treatment of ED.

Abstract
Organic erectile dysfunction (ED) is a type of sexual disorder in men that is usually associated with illness, surgical injury, normal aging and has a high incidence across the globe. And the essence of penile erection is a neurovascular event regulated by a combination of factors. Nerve and vascular injury are the main causes of erectile dysfunction. Currently, the main treatment options for ED include phosphodiesterase type 5 inhibitors (PDE5Is), intracorporeal injections and vacuum erection devices (VEDs), which are ineffective. Therefore, it is essential to find an emerging, non-invasive and effective treatment for ED. The histopathological damage causing ED can be improved or even reversed with hydrogels, in contrast to current therapies. Hydrogels have many advantages, they can be synthesized from various raw materials with different properties, possess a definite composition, and have good biocompatibility and biodegradability. These advantages make hydrogels an effective drug carrier. In this review, we began with an overview of the underlying mechanisms of organic erectile dysfunction, discussed the dilemmas of existing treatments for ED, and described the unique advantages of hydrogel over other approaches. Then emphasizing the progress of research on hydrogels in the treatment of ED.

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
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
PURPOSE To evaluate the clinical efficacy and patient satisfaction rates of low-intensity extracorporeal shockwave therapy LIESWT) in men with vasculogenic erectile dysfunction (ED) using Duolith SD1 machine. MATERIALS AND METHODS This prospective, randomized, double-blinded clinical trial included 60 men who were randomly assigned to LIESWT (n=30, active group) or placebo (n=30) over 6 weeks. Patient demographics, change in International Index of Erectile Function (IIEF)-5, Erection Hardness Score (EHS) and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) scores, and an overall satisfaction score (on a 5-point scale), were recorded. All patients were reviewed at 1, 3, and 6 months after completion of therapy. RESULTS There were 21 (70%) patients in the LIESWT group and 3 (10%) patients in the placebo group who had a 5-point or greater increase in IIEF-5 score (p=0.018). At 6-month study period, the mean IIEF-5 score was 18.8 (standard deviation [SD], 3.8) in the LIESWT group versus 14.8 (SD, 3.6) in the placebo group, difference in means between groups was 4.0 (95% confidence interval, 2.1-5.9; p<0.001). The EHS scores were higher in the LIESWT group with a mean of greater than 1.2 across the 1, 3, and 6 months compared to the placebo group (p<0.05). All patients completed the treatment study and there was no adverse event reported in terms of penile pain, bruising or deformity. There was a positive correlation between men who reported improvement in EF and treatment satisfaction level with LiESWT (p=0.008). CONCLUSIONS LIESWT improves erectile function in the short-term especially in men with mild to moderate ED, and those without a cardiometabolic disease.

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.

Low-Intensity Pulsed Ultrasound Alleviates Human Testicular Leydig Cell Senescence In Vitro. Int J Mol Sci 2022; 24:ijms24010418.

Abstract
Aging has a significant negative impact on human testicular function; steroidogenesis is gradually impaired, and testosterone replacement therapy still has many risks. Low-intensity pulsed ultrasound (LIPUS) has been used as a novel non-invasive treatment for male erectile dysfunction and other fields, and has been shown to increase testosterone levels in animal models. Testosterone is synthesized and secreted by Leydig cells (LCs), and the serum testosterone level decreases after aging due to the LCs senescence. However, the effect of LIPUS on human senescent LCs has not been reported. In this study, human senescent LCs were isolated and stimulated with different energy intensities in vitro, and cell morphology, cell apoptosis, cell proliferation, cell senescence levels, lipid droplet number, testosterone and INSL3 secretion levels were tested and analyzed. Quantitative Polymerase Chain Reaction (QPCR) and Western Blot were performed to compare cell senescence characteristics and the expression profile of key pathways of testosterone secretion, and transcriptome analysis was performed to explore the signaling pathways of LCs alteration after LIPUS stimulation. It was safe and effective to stimulate LCs with the 75 mW/cm2 energy of LIPUS in vitro, which not only improved the senescence phenotype, but also effectively enhanced the secretory function of LCs in vitro, and increased the expression of key pathways of the testosterone synthesis pathway. These results suggest that LIPUS could be used as a novel treatment to human senescent LCs with decreased testosterone secretion levels in vitro.

Myogenous Temporomandibular Disorders: Diagnostic Concepts and Prospective Pilot Study on Extracorporeal Shockwave Therapy. Diagnostics (Basel) 2022; 13:diagnostics13010051. [PMID: 36611343 PMCID: PMC9818132 DOI: 10.3390/diagnostics13010051] [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: 12/07/2022] [Revised: 12/20/2022] [Accepted: 12/22/2022] [Indexed: 12/28/2022] Open
Abstract
The aims of this article are to discuss the current, and potential future directions, in the diagnosis of myogenous temporomandibular disorders (M-TMD), as well as to report a pilot study to investigate the feasibility and clinical outcomes of extracorporeal shockwave therapy (ESWT) in the treatment of M-TMD. Forty-one adult patients presented with M-TMD were recruited into the study and randomized into two groups: Group 1 received ESWT treatment, whereas Group 2 received placebo treatment. The variables investigated were pain, measured by a numerical rating scale (NRS) and mouth opening. Twenty-six patients (Group 1: n = 14, mean age = 45.3 (16.7) years; Group 2: n = 12, mean age = 46.8 (19.7) years) completed 1-year follow up and were included into the final analysis. In both groups, reduction in pain and increase in MO (unassisted maximum, assisted maximum, and pain-free) were seen at post-treatment 1 year. There were more reduction in pain and increase in all MO in Group 1 than Group 2, but statistical significance was not detected. No major complications were encountered in this study. Although significant differences were not seen between groups, this prospective pilot study provided preliminary evidence that ESWT is safe and potentially beneficial in the treatment of M-TMD.

Andrologia 2022; 54:e14607. [PMID: 36240784 DOI: 10.1111/and.14607] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Revised: 09/07/2022] [Accepted: 09/15/2022] [Indexed: 11/28/2022] Open
Abstract
Patients are becoming increasingly reliant on online platforms for obtaining health information. Previous research has shown that the quality of information available on the internet regarding novel medical therapies is generally poor and frequently misleading. Shock wave therapy represents a novel restorative therapy for erectile dysfunction (ED) that has recently gained attention. We hypothesised that online sources regarding shock wave therapy for ED would be fraught with misleading claims and unreliable health information. Our objective was to evaluate the quality and readability of online medical information on shock wave therapy as a treatment for ED. Websites were generated using a Google search of 'shock wave therapy for erectile dysfunction' with location filters disabled. Readability was analysed using the Readable software (Readable.com, Horsham, United Kingdom). Quality was assessed independently by three reviewers using the DISCERN tool. Articles were subdivided into those from private clinic websites and those from universities or news media websites. Statistical analysis was conducted using the Student's t test. Nine articles that resulted from the Google search had mean readability scores as follows: Flesch-Kincaid grade level (10.8), Gunning-Fog Index (13.67), Coleman-Liau Index (12.74), Simple Measure of Gobbledygook (SMOG) Index (13.33), FORCAST Grade Level (11.33), and Automated Readability Index (11.08). The mean Flesch Reading Ease score was 46.4. The articles had a mean DISCERN score of 3.1, suggesting 'moderate quality' content. Articles from universities (n = 2) or news sources (n = 3) had significantly higher DISCERN scores than articles from private medical practices (n = 4). There was no difference in readability scores between the groups. Articles from private clinics are just as readable as those from universities or news media, but they are significantly more biased and misleading. The current online material relating to shock wave therapy for ED may not adequately inform patients in their medical decisions making, thereby necessitating closer collaboration between the sources disseminating information and urologists.

Abstract
Objective To evaluate the efficacy and safety of extracorporeal shockwave therapy (ESWT) for postherpetic neuralgia. Design Randomized single-blind clinical study. Patients Patients with postherpetic neuralgia. Methods Patients were randomly divided into the control group and the ESWT group. The control group received conventional treatment while the ESWT group received conventional treatment and ESWT. The primary outcome is pain degree as assessed by the numeric rating scale (NRS), and secondary outcomes include brief pain inventory (BPI), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and Pittsburgh Sleep Quality Index (PSQI). Data were collected at baseline and at weeks 1, 4, and 12. Linear mixed-effects models were applied to repeated measurement data. Results The scores on the NRS, BPI, SAS, SDS, and PSQI decreased over time in both groups. The NRS and SDS scores of the ESWT group were statistically lower than the control group. There was no time × group interaction in the mixed model analysis. Baseline age was correlated with NRS scores and BPI scores, and invasive treatment was related to PSQI scores, with no interaction effect for baseline confounders observed. No adverse events were observed during the process of this trial. Conclusion Extracorporeal shockwave therapy combined with conventional treatment could relieve pain and improve the psychological state in patients with postherpetic neuralgia without serious adverse effects.

Abstract
Low‐intensity shockwave therapy (LiSWT) has emerged as a promising non‐invasive treatment modality for erectile dysfunction (ED) yet the well‐designed randomized clinical trials are still lacking to prove its claimed benefits. A randomized, prospective, double‐blinded sham‐controlled study was conducted to evaluate the effectiveness and safety profile of short course LiSWT on vasculogenic ED patients. The International Index of Erectile Function‐5 (IIEF‐5) and Erection Hardness Score (EHS) questionnaires were used for evaluation. Patients underwent weekly sessions for 4 weeks and were re‐assessed at 1, 3 and 6 months post therapy. Fifty one patients were recruited and randomized into sham and treatment arms. The mean IIEF‐5 scores were significantly improved in the treatment arm compared to worsening of scores in the sham arm after 1 month (14.1 vs. 9.3 p < 0.001), 3 months (14.9 vs. 8.6, p < 0.001) and 6 months (14.2 vs. 7.9, p < 0.001) post treatment. A significant improvement of EHS was demonstrated at 1 month (2.4 vs. 1.8, p = 0.001, 3 months 2.7 vs. 1.7, p < 0.001) and 6 months (2.7 vs. 1.6, p < 0.001) in the treatment arm compared to sham arm. The success rate based on IIEF score increment more than five points was 26% in treatment arm and 0% in sham arm. Improvement in EHS score ≥3 in the treatment versus sham arm was 63% and 4%, respectively. There was no adverse effect reported. This 4‐week LiSWT protocol reflects better treatment compliance, and it prevents further deterioration of erectile function among this cohort of patients. This study proves that LiSWT is a well‐tolerated treatment with modest improvements in erectile function and hardness, among patients with vasculogenic ED.

Safety and efficacy of treating post-burn pathological scars with extracorporeal shock wave therapy: A meta-analysis of randomised controlled trials. Wound Repair Regen 2022; 30:595-607. [PMID: 35691021 DOI: 10.1111/wrr.13037] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Revised: 05/17/2022] [Accepted: 06/06/2022] [Indexed: 11/28/2022]
Abstract
The clinical application of shockwave therapy has expanded to the treatment of pathological scars. The objective of this systematic review and meta-analysis is to quantitatively evaluate the efficacy and safety of extracorporeal shockwave therapy combined with comprehensive rehabilitation therapy on post-burn pathological scars compared to comprehensive rehabilitation therapy alone. The randomised controlled trials of extracorporeal shockwave therapy for post-burn pathological scars published in English and Chinese languages before October 2021 were included. The methodological quality and risk of bias of the selected articles were assessed with the Cochrane Collaboration's 'risk of bias' tool. RevMan software was applied for data analysis. This is the first systematic review and meta-analysis considering the effectiveness and safety of extracorporeal shockwave therapy on post-burn pathological scars. And nine randomised controlled trials involving 422 patients were included in this meta-analysis. The meta-analysis results showed that, compared with comprehensive rehabilitation therapy alone, extracorporeal shockwave therapy combined with comprehensive rehabilitation therapy was more effective in relieving pain (standardized mean difference [SMD] = -0.59, 95% confidence interval [CI]: [-0.87 to -0.31], p < 0.0001) and pruritus related to pathological scars (SMD = -0.94; 95% CI: [-1.25 to -0.63], p = 0.004), improving scars' appearance (SMD = -1.78, 95% CI: [-3.37 to -0.19], p = 0.03) and elasticity (SMD = 0.25, 95% CI: [0.29-0.21], p < 0.00001), decreasing scars thickness (SMD = -0.13, 95% CI: [-0.25 to -0.01], p = 0.04) and promoting the maturation status of scars (SMD = -2.86, 95% CI: [-3.96 to -1.76], p < 0.00001). There were no reported serious adverse events during and after extracorporeal shockwave therapy in the included studies. Available data preliminarily suggested that the combination of extracorporeal shockwave therapy and comprehensive rehabilitation therapy had better therapeutic effect on post-burn pathological scars than comprehensive rehabilitation therapy alone, without obvious side effects. However, further clinical well-controlled randomised controlled trials are needed. Systematic review registration ID: PROSPERO CRD42022297573.

Abstract
To identify factors that could influence the treatment outcomes of low-intensity extracorporeal shock wave therapy (Li-ESWT) on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)-like symptoms and establish a predictive model based on these factors to precisely screen individuals who might be more suitable for Li-ESWT. This study enrolled 84 patients with CP/CPPS-like symptoms who received Li-ESWT. Patients were divided into an effective group and an ineffective group based on the reduction of their National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). A nomogram was established based on logistic regression analyses. Then, receiver operating characteristic (ROC) curves, calibration curves and decision curve analysis (DCA) were used to evaluate the nomogram. Univariate and multivariate logistic regression analysis showed that a higher NIH-CPSI score, a habit of holding urine, alcohol consumption, and urination soon after intercourse were independent predictors of Li-ESWT efficacy (p < 0.05). The nomogram constructed based on these four indicators and the added age effectively predicted the probability of Li-ESWT effectiveness for CP/CPPS-like symptoms (0.809 [95% CI: 0.717-0.901]; Hosmer-Lemeshow: p = 0.936). This study established a predictive model for the efficacy of Li-ESWT in treating CP/CPPS-like symptoms patients and help improve the management of CP/CPPS-like symptoms.

Abstract
BACKGROUND Erectile dysfunction (ED) may be common in patients with inflammatory bowel disease (IBD), but its prevalence and risk factors still remain debatable. AIM To evaluate the prevalence of ED in the IBD population and the potential role of risk factors in the development of ED. METHODS An extensive search in the PubMed, Cochrane Library, and Web of Science was performed to identify relevant English-language articles published up to December 2021 that evaluated the prevalence of ED on IBD patients. The included studies were evaluated by 2 independent reviewers for eligibility. We used an adapted Assessment Tool for Prevalence Studies to evaluate the quality of enrolled studies. Data were analyzed and graphed using the STATA software (version 16.0; Stata Corporation, College Station, TX, USA). The ORs with 95% CIs were pooled using a fixed or random-effects model according to heterogeneity. Subgroup analysis was performed to explore the source of heterogeneity. Sensitivity analysis was conducted to evaluate the stability of the results. OUTCOMES The pooled prevalence of ED in IBD patients was calculated, and the OR value and 95% CIs were used to assess the strength of the association between IBD-related risk factors and ED. RESULTS Fourteen studies included 32,858 individuals totally were enrolled for this meta-analysis. The overall pooled prevalence estimate of ED in IBD patients was 27% (95% CI: 20-34%). Operation (OR 1.28; 95% CI: 1.17-1.39; P < .00001; I2 = 0.0%), disease activity (OR 2.06; 95% CI: 1.07-3.05; P < .00001), and depression (crude OR 3.31; 95% CI: 1.08-5.54; P = .004; I2 = 0.0%) significantly increase the risk of ED in people with IBD. The association of depression and ED was further confirmed by calculating the pooled estimates of adjusted OR (1.58; 95% CI: 0.05-3.12; P < .05; I2 = 0.0%). The pooled prevalence estimates of ED were 30, 33, and 17% in the age <40, IIEF diagnostic tool, and IPAA surgery subgroups, respectively. CLINICAL IMPLICATIONS IBD patients had a significantly increased prevalence of ED, indicating that erectile function in men with IBD should be concerned by clinicians. STRENGTHS & LIMITATIONS The strength of this study is that this is the first meta-analysis to assess the global prevalence and risk factors of ED in IBD patients. A limitation is that the results after pooling the included articles showed significant heterogeneity. CONCLUSION The results of our meta-analysis and systematic review provide evidence of the high prevalence and risk factors of ED in IBD patients. Wu X, Zhang Y, Zhang W, et al.

Abstract
Erectile dysfunction (ED) is a well-known complication of radical prostatectomy (RP). Oral 5-phosphodiesterase inhibitors are currently the most widely used penile rehabilitation treatment for ED following RP, but they are less effective than for those with general ED. Low-intensity extracorporeal shock wave treatment (LI-ESWT), causing a biological change that induces neovascularization, has recently been used as a treatment for ED. Therefore, we conducted a systematic review and meta-analysis to investigate the efficiency of LI-ESWT in ED following RP. PubMed, Embase, and the Cochrane Library were searched up until December 2021. The endpoint was the change in IIEF scores after LI-ESWT. Five papers (460 patients) were included in the final analysis. In IIEF scores performed 3–4 months after LI-ESWT, the group receiving LI-ESWT showed statistically significantly better results than the control (WMD = −2.04; 95% CI, −3.72 to −0.35; p = 0.02). However, there were a total of two studies that measured the results after 9–12 months. There was no statistical difference between the two groups (WMD = −5.37; 95% CI, −12.42 to 1.69; p = 0.14). The results of this analysis indicate that LI-ESWT showed a statistically significant effect on early recovery in penile rehabilitation of ED following RP. However, the level of evidence was low. Therefore, careful interpretation of the results is required.

Abstract
INTRODUCTION Radial wave therapy is commercialized as an option for the management of erectile dysfunction. However, the mechanism of action of the radial waves differs substantially from shock waves, so the evidence gathered for shock wave therapy cannot be extrapolated, and there are very few clinical trials with the radial wave. AIM To assess the efficacy and safety of radial wave therapy compared with sham therapy for the treatment of moderate and mild to moderate erectile dysfunction. METHODS A randomized, double-blind, sham-controlled clinical trial was realized. Eighty patients with moderate erectile dysfunction, without sickle cell anemia, anticoagulation treatment, comorbidities, or conditions associated with secondary erectile dysfunction were included. The efficacy and safety were assessed at 6 and 10 weeks after randomization. Patients were randomized 1:1 to 1 of 2 arms: (i) 6 weekly sessions of radial wave therapy (RW group) or (ii) 6 weekly sessions of sham therapy (control group). All patients received sildenafil 25 mg. OUTCOME The primary outcome was the mean change in the International Index of Erectile Function - Erectile Function (IIEF-EF) domain score at 6 weeks after randomization. RESULTS Eighty men were randomized. The average baseline IIEF-EF score was 16.3 (Standard Deviation - SD 3.2), and the median baseline Erection Hardness Score (EHS) was 3 (IQR 1). At 6 weeks after randomization, the mean change in the IIEF-EF score was 3.4 (95% confidence interval [CI] 1.5-5.2) in the RW group and 4.2 (95% CI 2.5-5.9) in the control group. No differences were observed between groups (P value =.742). No change was observed in the median EHS score in the evaluations. No serious adverse events occurred in 2 (5%) patients after radial wave therapy, and in 1 (2.5%) patient after sham therapy. CLINICAL IMPLICATIONS Knowledge of the effectiveness of radial waves protocols used for the treatment of moderate erectile dysfunction, helps doctors and patients in making decisions about the use of this therapy. STRENGTHS & LIMITATIONS One strength is conducting the study with high methodological standards to minimize risk biases. Our results are limited to the evaluation of 1 specific protocol in moderate and mild to moderate erectile dysfunction. CONCLUSIONS No difference was found in this study between men with moderate and mild to moderate erectile dysfunction treated with radial waves and men treated with placebo sham therapy. Studies with different protocols of radial waves are necessary. Sandoval-Salinas C, Saffon JP, Martínez JM, et al.

Abstract
Shock Waves (SW) are acoustic disturbances that propagate through a medium carrying the energy. These specific sonic pulses are composed of two phases—high positive pressure, a rise time < 10 ns, and a tensile wave. Originally Shock Waves were introduced to clinical practice as a part of the lithotripsy therapy focused on disrupting calcific deposits in the body. Since that time, shock wave therapy (SWT) has gone far beyond the original application related to the destruction of kidney stones. In this narrative Review, we present basic clinical applications of the SWT along with the potential therapeutic application in clinical practice.

Analysis of the Impact of Clinical Factors on Low-Intensity Extracorporeal Shockwave Therapy for Erectile Dysfunction. Urol Int 2022; 106:1041-1049. [PMID: 35144264 DOI: 10.1159/000520705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Accepted: 11/01/2021] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Predictive factors for the treatment success of low-intensity extracorporeal shockwave therapy (Li-ESWT) for erectile dysfunction (ED) are still under debate. METHODS Li-ESWT was performed in 50 patients suffering from ED by applying 3,000 shock waves once a week over a period of 6 weeks. Treatment success was defined as an increase in the International Index of Erectile Function 5 (IIEF-5) score by ≥5 points or an Erectile Hardness Score (EHS) of ≥3 points. IIEF-5 and EHS were measured at baseline and at 3 and 6 months of follow-up. RESULTS Treatment success according to either the IIEF-5 score or EHS at any time of follow-up was achieved in 28 patients (56%). Twenty-five patients (50%) experienced an improvement during the first 3 months, which lasted for 6 months in 8 cases (16%). Three patients reported improved erectile function only after 6 months. When stratifying the cohort with regard to potential influencing factors, a significantly improved IIEF-5 score could be achieved in men with cardiovascular risk factors (p = 0.026) and in men with antihypertensive medication (p = 0.009). Men without cardiovascular risk factors showed no therapeutic benefit from Li-ESWT. DISCUSSION/CONCLUSION Li-ESWT is a valid but often short-lived treatment option for ED, especially in men with cardiovascular risk factors or controlled hypertension. Future studies should assess the feasibility and safety of repeated applications of Li-ESWT.

Abstract
INTRODUCTION The terminology for sexual health in men with lower urinary tract (LUT) and pelvic floor (PF) dysfunction has not been defined and organized into a clinically based consensus terminology report. The aim of this terminology report is to provide a definitional document within this context that will assist clinical practice and research. METHODS This report combines the input of the members of sexual health in men with LUT and PF Dysfunction working group of the International Continence Society (ICS), assisted at intervals by external referees. Appropriate core clinical categories and a sub-classification were developed to give coding to definitions. An extensive process of 18 rounds of internal and external review was involved to exhaustively examine each definition, with decision-making by collective opinion (consensus). The Committee retained evidence-based definitions, identified gaps, and updated or discarded outdated definitions. Expert opinions were used when evidence was insufficient or absent. RESULTS A terminology report for sexual health in men with LUT and PF dysfunction, encompassing 198 (178 NEW) separate definitions, has been developed. It is clinically based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different speciality groups involved. Conservative and surgical managements are major additions and appropriate figures have been included to supplement and clarify the text. Emerging concepts and measurements, in use in the literature and offering further research potential, but requiring further validation, have been included as an appendix. Interval (5-10 years) review is anticipated to keep the document updated. CONCLUSION A consensus-based terminology report for sexual health in men with LUT and PF dysfunction has been produced to aid clinical practice and research. The definitions that have been adopted are those that are most strongly supported by the literature at this time or are considered clinical principles or consensus of experts' opinions.

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.

The Effect of Combination Treatment with Low-Intensity Shockwave Therapy and Tadalafil on Mild and Mild-To-Moderate Erectile Dysfunction: A Double-Blind, Randomized, Placebo-Controlled Clinical Trial. J Sex Med 2022; 19:106-115. [PMID: 34866029 DOI: 10.1016/j.jsxm.2021.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 10/18/2021] [Accepted: 10/23/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Combination of different first-line treatments for erectile dysfunction (ED) has emerged as a promising therapeutic approach. AIM To conduct the first double-blind, randomized, placebo-controlled clinical trial to evaluate the efficacy and safety of combination therapy with low-intensity shockwave therapy (LiST) and tadalafil vs LiST and placebo in patients with mild or mild-to-moderate vasculogenic ED. METHODS Fifty sexually active patients fulfilling the eligibility criteria were randomly assigned to 6 sessions of LiST twice weekly for 3 weeks and tadalafil (n = 25) or placebo (n = 25) once daily for 4 weeks. Patients were evaluated at 1, 3, and 6 months after completion of the treatment protocol. OUTCOMES The primary outcome was the mean change from baseline in the International Index of Erectile Function-Erectile Function (IIEF-EF) domain between the 2 groups at 3 months after treatment. Erectile function was also assessed at 1 and 6 months. The number of patients attaining a minimal clinically important difference (MCID) in the IIEF-EF, as well as the safety of combination therapy were evaluated. RESULTS Adjusting for the baseline values, IIEF-EF improved by 0.8 points more (95% confidence interval [CI] = -0.2 to 1.9, P = .12) at 1 month, 1 point more (95% CI = 0.1-1.9, P = .02) at 3 months and 1.7 points more (95% CI = 0.8-2.7, P < .001) at 6 months in patients treated with combination therapy compared to monotherapy. The number of patients attaining a MCID in the IIEF-EF between the 2 groups improved significantly only at the 3-month evaluation. No adverse events were reported during the whole study period. CLINICAL IMPLICATIONS Combination of LiST twice weekly for 3 weeks and tadalafil 5 mg once daily for 4 weeks may further ameliorate mild or mild-to-moderate vasculogenic ED compared to LiST monotherapy. STRENGTHS & LIMITATIONS We conducted the first randomized trial exploring the role of LiST and tadalafil in the management of ED. Conversely, our study lacks external validity due to its single-center design. CONCLUSION The addition of daily low-dose tadalafil during application of LiST may further improve erectile function compared to application of LiST as a standalone treatment in patients with mild or mild-to-moderate vasculogenic ED. Still, further high-quality studies are warranted to corroborate our findings.

Abstract
The purpose of this study is to evaluate the results of two courses of low-intensity shock wave therapy (Li-SWT) in the treatment of patients with erectile dysfunction (ED). Between June 2015 and December 2020, diabetic and non-diabetic patients with ED treated with two Li-SWT courses were evaluated retrospectively among the data of 317 patients. The outcomes were evaluated using the International Index of Erectile Function-Erectile Function Domain (IIEF-EF) questionnaire values at baseline and 6 months post-treatment for each Li-SWT course with (0.09 mJ/mm²) 18000 shock waves. Successful treatment criteria for patients who also underwent physical examination and anamnesis before and after each course were IIEF-EF scores≥26 during the 6 months follow-up. Forty-one patients with a mean age of 51.61 ± 11.80 years were included in the study. The mean IIEF-EF scores were 15.17 ± 3.75 at baseline, 21.61 ± 3.60 after the first course [mean difference(MD): -6.439; 95%, confidence interval(CI), -7.138: -5.740; t = -18.621; p < 0.001], and 25.27 ± 4.05 after the second course(MD: -3.658; 95% CI, -4,067: -3.249; t = -18,071; p < 0.001). Evaluation of score increases in diabetic patients was also statistically significant for each course (p < 0.001). Our study shows that two courses of Li-SWT treatments are safe for both diabetic and non-diabetic patients with ED and effective for each course.

Abstract
Background Low-intensity extracorporeal shockwave therapy (LI-ESWT) may be a successful complementary treatment approach for erectile dysfunction (ED). In this study, we aimed to review and summarize the research evidence from systematic reviews (SRs)/meta-analyses (MAs) regarding the clinical effectiveness of LI-ESWT for ED. Methods Studies on LI-ESWT for ED were searched using eight electronic databases from establishment of each database to 31 June 2021 with the language restrictions of Chinese and English. All articles were screened, and qualifying data were recorded based on the inclusion criteria. Methods including: the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2); the Risk of Bias in Systematic Reviews (ROBIS); the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA); and Grading of Recommendations, Assessment Development, and the Evaluation (GRADE) were used by two independent raters to assess methodological quality, risk of bias, reporting quality, and SR evidence of quality, respectively. Results Eight SRs/MAs met all inclusion criteria. Seven reviews were rated as critically low on overall confidence and one review was low on confidence based on the AMSTAR-2 appraisal tool. While most PRISMA criteria were met, the major reporting flaws were in relation the financial statements not being included, along with no protocol registrations. Three SRs/MAs were classed as low risk regarding bias as measured by the ROBIS tool. Based on the GRADE method, only one SRs/MAs of high-quality evidence and seven SRs/MAs of moderate-quality evidence were found. The present research results supported LI-ESWT as a complementary therapy for ED patients, but the evidence should be considered carefully due to the methodological flaws identified. Discussion Our results showed that LI-ESWT as an adjunctive therapy has benefits for ED patients. There were no obvious side effects, and the number of shockwave treatments and energy flux density (EFD) would affect the IIEF-EF, EHS and PSV scores. However, due to the limited sample size and the quality of reporting evidence, our conclusions may not be fully representative.

Abstract
Background: Histological and functional recovery after peripheral nerve injury (PNI) is of significant clinical value as delayed surgical repair and longer distances to innervate terminal organs may account for poor outcomes. Low-intensity extracorporeal shock wave therapy (LiESWT) has already been proven to be beneficial for injured tissue recovery on various pathological conditions. The objective of this study was to explore the potential effect and mechanism of LiESWT on PNI recovery. Methods: In this project, we explored LiESWT's role using an animal model of sciatic nerve injury (SNI). Shockwave was delivered to the region of the SNI site with a special probe at 3 Hz, 500 shocks each time, and 3 times a week for 3 weeks. Rat Schwann cells (SCs) and rat perineurial fibroblasts (PNFs) cells, the two main compositional cell types in peripheral nerve tissue, were cultured in vitro, and LiESWT was applied through the cultured dish to the adherent cells. Tissues and cell cultures were harvested at corresponding time points for a reverse transcription-polymerase chain reaction, Western blotting, and immunofluorescence staining. Multiple groups were compared by using one-way analysis of variance followed by the Tukey-Kramer test for post hoc comparisons. Results: LiESWT treatment promoted the functional recovery of lower extremities with SNI. More nerve fibers and myelin sheath were found after LiESWT treatment associated with local upregulation of mechanical sensitive yes-associated protein (YAP)/transcriptional co-activator with a PDZ-binding domain (TAZ) signaling pathway. In vitro results showed that SCs were more sensitive to LiESWT than PNFs. LiESWT promoted SCs activation with more expression of p75 (a SCs dedifferentiation marker) and Ki67 (a SCs proliferation marker). The SCs activation process was dependent on the intact YAP/TAZ signaling pathway as knockdown of TAZ by TAZ small interfering RNA significantly attenuated this process. Conclusion: The LiESWT mechanical signal perception and YAP/TAZ upregulation in SCs might be one of the underlying mechanisms for SCs activation and injured nerve axon regeneration.

Abstract
Purpose The aim of this study was to investigate whether ESWT with a higher energy as an add-on therapy to vacuum-pump followed by manipulation exercises could reduce the penile curvature, pain and improve IIEF-5 score. Materials and Methods Men aged >18 and <80 years and diagnosed with PD in stable phase with no history of penile surgery or previous ESWT treatment were eligible to participate. They were randomised to either active ESWT (n = 16) or sham ESWT (n = 16). Both groups were treated once a week for five weeks. Each treatment session consisted of 2000 shockwaves at 0.5mJ/mm2. All patients in both groups used a vacuum pump followed by manipulation exercises. Results Thirty men completed the study protocol. Mean age in the treatment group was 61.7 (SD 8.3) and 63 (SD 7.35) in the control group. After six months, mean change in penile curvature was −12.8 (SD 13) degrees in the treatment group and −6.6 (SD 8.9) in the control group (p = 0.204). Mean IIEF-5 score decreased by 0.17 (SD 3) in the treatment group and 3.06 (SD 5.5) in the control group (p = 0.086) at six-month follow-up. Pain was assessed using both VAS and PDQ and demonstrated no difference between the groups after six months (p = 0.648). Conclusion In the treatment group, we observed a greater but non-significant change in penile curvature and no adverse effects.

Geyik S. Comparison of the efficacy of low-intensity shock wave therapy and its combination with platelet-rich plasma in patients with erectile dysfunction. Andrologia 2021; 53:e14197. [PMID: 34350629 DOI: 10.1111/and.14197] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 07/13/2021] [Accepted: 07/14/2021] [Indexed: 02/06/2023] Open
Abstract
We aimed to compare the efficacy of low-intensity shock wave therapy (Li-SWT) alone and its combination with platelet-rich plasma (PRP) in the treatment of patients with erectile dysfunction (ED). Between January 2015 and October 2020, patients who did not benefit from the use of phosphodiesterase type 5 inhibitors (PDE5i; 5 mg/day) for at least 3 months and underwent Li-SWT or Li-SWT with PRP were evaluated retrospectively. There were 93 patients who were subjected to Li-SWT only (Group 1) and 91 patients subjected to Li-SWT with PRP (Group 2). Analysis of the International Index of Erectile Function-Erectile Function Area (IIEF-EF) scores showed a significant increase in both the groups post-treatment (Group 1: from 14.33 ± 4.39 to 23.8 ± 4.37, p = .001; Group 2: from 17.82 ± 3.44 to 26.3 ± 2.55, p = .001). When the increase in the IIEF-EF scores was compared pre- and post-treatment between the groups with respect to the ED grades, there was no statistically significant difference between them. Furthermore, while the intravaginal ejaculatory latency time (IELT) in successfully treated patients of Group 1 remained the same, Group 2 presented 1.5-3.5 times (mean, 2.4) prolongation. Their mean IELT score showed an increase from 2.2 (0.8-3.5) min to 5.3 (2.8-10.5) min. Our study shows that combination treatment of Li-SWT with PRP injections is not only safe for patients with ED, but also effective and safe in prolonging the IELT.

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.

Abstract
Introduction Low intensity extracorporeal shock wave therapy (LIESWT) improves erectile function (EF) in men with vascular erectile dysfunction (ED) but longer-term outcomes remain unknown. Aim To evaluate the clinical outcomes of LIESWT at a minimum 5-year follow-up. Methods This is an open-label single-arm prospective study involved men with vascular ED who received LIESWT. Main Outcome Measure Changes in patient demographics, IIEF-5 and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) scores, as well as overall satisfaction score (on a 5-point scale) were reviewed at 12, 24, 48, and 60 months after completion of LIESWT. A chi-square contingency analysis was used to examine the relationship between erectile function score and treatment satisfaction, with statistical significance set at 5%. Results The mean follow-up period was 69.9 (63–82; median 76) months. The mean IIEF-5 scores for pretreatment and after treatment at 12, 24, 48, and 60 months were 14.8, 17.6, 16.8, 16.5, and 16.5 while the percentages of patients who reported an improvement in IIEF-5 score by 5 points were 60%, 45%, 40%, and 40%; and EDITS scores >50% were recorded in 70%, 55%, 50%, and 48% of patients at 12, 24, 48, and 60 months post-LIESWT. Ten patients required medical therapy and 2 patients opted for penile prosthesis implantation. The overall satisfaction rate appeared sustained subsequent follow-up (score 4 out of 5; 68% vs 50% vs 40% vs 40% at 12, 24, 48, and 60 months). There were minor time-limited, but no significant adverse event reported. Conclusion This long-term study showed the observed clinical improvement in EF continues to deteriorate but appears to plateau at 40% clinical efficacy at 48–60 months after completion of LIESWT. The absence of penile pain and deformity at 5-year follow-up supports the long-term safety data of LIESWT in men with ED. Chung E, Cartmill R.

Abstract
Erectile dysfunction (ED) impacts a significant portion of the aging male population. Standard treatments such as oral medications, intracavernosal injections, intraurethral suppositories, vacuum erection aids, and penile prosthesis placement have stood the test of time. Recently, there has been a growing interest in the concept of regenerative medicine with the goal of restoring or renewing functional tissue. Low intensity shock wave therapy (LiSWT) is one example of a regenerative therapy. A strong body of basic science data suggests that shockwaves, when applied to local tissue, will encourage blood vessel and nerve regeneration. Clinical evidence supports the use of LiSWT to treat conditions ranging from ischemic heart disease, musculoskeletal injuries, and even chronic non-healing wounds. LiSWT is also being used to treat male sexual dysfunction conditions such as Peyronie's Disease and ED. The first studied application of LiSWT for ED was published in 2010. Since then multiple randomized, sham-controlled trials have sought to evaluate outcomes for this novel therapy in men with vasculogenic ED. Additionally, several meta-analyses are available with pooled data suggesting that LiSWT results in a significantly greater improvement in erectile function relative to sham-control. Despite these promising findings, the current body of literature is marred by significant heterogeneity relating to treatment protocols, patient populations, and follow-up duration. Further work is necessary to determine optimal device technologies, patient characteristics, and treatment duration prior to considering LiSWT as standard of care for men with ED.

Abstract
INTRODUCTION Our purpose was to assess the efficacy of low intensity extracorporeal shock waves (SW) for the treatment of organic erectile dysfunction (ED). METHODS A systematic review of the literature published between 2000 and 2020 was conducted using the PRISMA methodology. We used Medline data with the following key words (MesH): "extracorporeal shock wave therapy"; "erectile dysfunction"; "sexuality". RESULTS Nineteen articles were selected: thirteen randomised controlled trial and six meta-analyses. Most of them studied vascular etiology. Low intensity SW is beneficial ED is evaluated by the IIEF, EHS scores and penile hemodynamic. CONCLUSION SW may have a theoretical impact on the vascular etiology of organic DE. Their use in this context is supported by the European Society of urology and the European Society of sexual medecine. However, there are discrepancies in current data to establish a protocol to follow in daily practice.

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
Introduction Previous studies have indicated that low-intensity extracorporeal shockwave therapy (Li-ESWT) may improve male erectile dysfunction (ED) of vascular aetiology. Aim To investigate penile rehabilitation of Li-ESWT in a randomized, placebo-controlled trial in men with ED following robotic nerve-sparing radical prostatectomy (RARP). Methods Included were men with ED following nerve-sparing RP with a score <22 in the 5-item International Index of Erectile Function (IIEF-5) questionnaire. Participants were divided into an active A (n = 20) and a placebo/sham B group (n = 18). They were randomized consecutively upon study entry. Each study arm had one treatment a week for 5 weeks. Main outcome measures Sexual outcomes were assessed by international validated questionnaires, Erection Hardness Score (EHS) and IIEF-5 at baseline and at 4 and 12 weeks after treatment. Results A total of 38 (n = 38) participants were enrolled; there were no dropouts. A significant increase was observed in IIEF-5 and EHS in group A at both 4 and 12 weeks. At 12 weeks, the mean IIEF-5 score had increased by 3.45 points (P = .026), while the mean EHS score had increased by 0.5 points (P= .019). Conclusion This randomized study indicates that Li-ESWT for ED in men undergone RP might be effective and safe. However, further and more robust research is needed before Li-ESWT can be characterized as a reliable treatment modality. Ladegaard PBJ, Mortensen J, Skov-Jeppesen SM, et al.
