He S, Zhang S, Sun X, Liu R, Yuan T, Chen X, Zhang X. Global research trends on the links between prostate cancer and erectile dysfunction between 2003 and 2023: A bibliometrics and visualized study. Heliyon 2024; 10:e33834. [PMID: 39027554 PMCID: PMC11255577 DOI: 10.1016/j.heliyon.2024.e33834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/23/2024] [Accepted: 06/27/2024] [Indexed: 07/20/2024] Open
Abstract
Background The incidence of prostate cancer (PC) has increased in recent years. Erectile dysfunction (ED) after prostate cancer treatment has aroused extensive attention. Bibliometric analysis was designed to investigate a systematic understanding of developments between PC and ED during the past 20 years. Methods Literatures on PC and ED were retrieved from the Web of Science Core Collection database (WoSCC). By using the VOS viewer and CiteSpace software to analysis the metrics of bibliometric literature, such as number of articles, journals, countries, institutions, authors, keywords and associated information. The number of publications per year was statistically analysed and plotted thorough Microsoft Office. In addition, Pajek software was used to adjust the visual map. Results A total of 2332 screened articles were included in the analysis. The Journal of Sexual Medicine, ranking first among the analysed journals, published 235 articles. The United States and Canada were leaders in PC and ED research. There is a need to strengthen inter-agency cooperation in this area of research on a global scale. Mulhall JP, as the most prolific author in this area of research, published 80 articles. And Rosen RC was the author with the most co-citated (693 co-citated). The main research focus on the prevention, treatment and management of ED after PC treatment in this field through the keyword analysis. Conclusions Research on PC and ED is expected to expand further worldwide. We found ED, as new sustainable treatment modalities, scientific postoperative management and psychological interventions for patients, may become the research hotspots and should be closely concerned in this study.

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.

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.

Comparison of the efficacy of the early LI-SWT plus daily tadalafil with daily tadalafil only as penile rehabilitation for postprostatectomy erectile dysfunction. Int J Impot Res 2023; 35:447-453. [PMID: 35347300 PMCID: PMC10335924 DOI: 10.1038/s41443-022-00560-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 03/01/2022] [Accepted: 03/08/2022] [Indexed: 02/07/2023]
Abstract
This study compares the efficacy of the early low-intensity shock wave therapy (LI-SWT) plus daily tadalafil with daily tadalafil only therapy as penile rehabilitation for postprostatectomy erectile dysfunction in patients with prostate cancer who underwent bilateral interfascial nerve-sparing radical prostatectomy (robotic or open). From April 2019 to March 2021, 165 patients were enrolled, and 80 of them successfully completed this prospective study. Daily tadalafil were administered to all the patients. LI-SWT consisted of a total of six sessions. Each session was performed on days 4, 5, 6, and 7, and on the second and fourth weeks after surgery. Each LI-SWT session consisted of 300 shocks at an energy density of 0.09 mJ/mm2 and a frequency of 120 shocks per minute that were delivered at each of the five treatment points for 15 min. Thirty-nine patients were treated with tadalafil-only (group A) while 41 were treated with tadalafil and LI-SWT simultaneously (group B). At postoperative 6 months, the proportion of patients with erection hardness scores (EHS) ≥ 3 (4/39 vs. 12/41) was significantly higher in group B (p = 0.034), and LI-SWT was the only independent factor for predicting EHS ≥ 3 (OR, 3.621; 95% CI, 1.054-12.437; p = 0.041). There were no serious side effects related to early LI-SWT. Early LI-SWT plus daily tadalafil therapy as penile rehabilitation for postprostatectomy erectile dysfunction is thought to be more efficacious than tadalafil only. Further large-scaled randomized controlled trials will be needed to validate these findings.

Long-term efficacy of penile rehabilitation with low-intensity extracorporeal shock wave therapy for sexual and erectile function recovery following robotic-assisted radical prostatectomy: a single-cohort pilot study. Sex Med 2023; 11:qfad023. [PMID: 37228769 PMCID: PMC10204648 DOI: 10.1093/sexmed/qfad023] [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: 12/31/2022] [Revised: 03/20/2023] [Accepted: 04/11/2023] [Indexed: 05/27/2023] Open
Abstract
Background The long-term efficacy of low-intensity extracorporeal shock wave therapy (LIESWT) for penile rehabilitation after robot-assisted radical prostatectomy (RARP) has not yet been reported. Aim To assess the long-term efficacy of LIESWT for penile rehabilitation after RARP by evaluating the postoperative recovery of sexual and erectile functions following RARP. Methods Patients who underwent RARP at our institution were categorized into 2 groups: those who received LIESWT and those who underwent penile rehabilitation with a phosphodiesterase type 5 inhibitor (PDE5i). The control group included patients who did not undergo penile rehabilitation. Potency and scores on the Expanded Prostate Cancer Index Composite for sexual function and 5-item International Index of Erectile Function (IIEF-5) were evaluated preoperatively and over 60 months after RARP. Outcomes The LIESWT group had significantly higher postoperative sexual function and total IIEF-5 scores and potency than the control group over the long term, and its results were not inferior to those of the PDE5i group. Results The LIESWT, PDE5i, and control groups comprised 16, 13, and 139 patients, respectively. As compared with the control group, the LIESWT group had significantly higher sexual function scores at 6, 12, and 60 months after surgery (P < .05) and total IIEF-5 scores at 24 and 60 months (P < .05). The LIESWT group also had a significantly higher potency rate than the control group at 60 months (P < .05). For all time points after surgery, there were no significant differences between the LIESWT and PDE5i groups in terms of sexual function and total IIEF-5 scores and potency. Clinical Implications LIESWT may be a new option for penile rehabilitation in patients with erectile dysfunction after RARP. Strengths and Limitations This pilot study was performed at a single center and involved relatively few patients, which may have led to selection bias. Furthermore, the selection of this study for penile rehabilitation was not made randomly but by the patient's choice. Despite these limitations, our results provide evidence in support of LIESWT for penile rehabilitation after RARP because this is the first study to assess the long-term efficacy of LIESWT. Conclusion LIESWT can improve sexual and erectile functions in patients with erectile dysfunction after RARP, and its efficacy can be maintained over a long period after surgery.

Abstract
Prostate cancer is the most frequently diagnosed cancer in men in the United States. Among the different available treatment options, radiation therapy is recommended for localized or even advanced disease. Erectile dysfunction (ED) often occurs after radiation therapy due to neurological, vascular, and endocrine mechanisms resulting in arterial tone alteration, pudendal-nerve neuropraxia, and lastly fibrosis. Considering the influence of quality of life on patients’ treatment choice, radiation-therapy-induced ED prevention and treatment are major issues. In this narrative review, we briefly summarize and discuss the current state of the art on radiation-therapy-induced ED in PCa patients in terms of pathophysiology and available treatment options.

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.

Penile Rehabilitation after Prostate Cancer Treatment: Which Is the Right Program? URO 2023. [DOI: 10.3390/uro3010009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 02/25/2023]
Abstract
The management of sexual complications after treatment of localized prostate cancer, such as erectile dysfunction, changes in the length of the penis, pain during sexual intercourse, and lack of orgasm, is still an unsolved problem with an important impact on patients’ quality of life. In this review, we summarize the current scientific literature about the rehabilitation of erectile dysfunction after prostate cancer treatment. The therapy for penile rehabilitation includes different types of treatments: the combination of phosphodiesterase type 5 inhibitors (PDE5-I) and the vacuum erectile device (VED) are considered first-line treatment options. When therapy begins, the duration of treatment, the dosage and the drug used all play very important roles in the treatment outcome. Intracavernous injection (ICI) therapy represents the second-line option for patients ineligible for PDE5-I therapy. Technological development has led to the emergence of devices for the stimulation of the penis without the use of drugs, such as penile vibratory stimulation (PVS) for stimulation of ejaculation in spinal cord injury and low-intensity extracorporeal shockwave therapy (LIESWT). The rapid diffusion of the latter, thanks to its easy use, attains good results without side effects. The panorama of penile rehabilitation after PC treatments is vast and many studies are needed, especially on new technologies, to find the best therapeutic regimen possible, personalized to the patient’s characteristics and the type of treatment for PC.

Abstract
Erectile dysfunction (ED) is the most common male sexual dysfunction by far and the prevalence is increasing year after year. As technology advances, a wide range of physical diagnosis tools and therapeutic approaches have been developed for ED. At present, typical diagnostic devices include erection basic parameter measuring instrument, erection hardness quantitative analysis system, hemodynamic testing equipment, nocturnal erection measuring instrument, nerve conduction testing equipment, etc. At present, the most commonly used treatment for ED is pharmacological therapy represented by phosphodiesterase five inhibitors (PDE5i). As a first-line drug in clinical, PDE5i has outstanding clinical effects, but there are still some problems that deserve the attention of researchers, such as cost issues and some side effects, like visual disturbances, indigestion, myalgia, and back pain, as well as some non-response rates. Some patients have to consider alternative treatments. Moreover, the efficacy in some angiogenic EDs (diabetes and cardiovascular disease) has not met expectations, so there is still a need to continuously develop new methods that can improve hemodynamics. While drug have now been shown to be effective in treating ED, they only control symptoms and do not restore function in most cases. The increasing prevalence of ED also makes us more motivated to find safer, more effective, and simpler treatments. The exploration of relevant mechanisms can also serve as a springboard for the development of more clinically meaningful physiotherapy approaches. Therefore, people are currently devoted to studying the effects of physical therapy and physical therapy combined with drug therapy on ED. We reviewed the diagnosis of ED and related physical therapy methods, and explored the pathogenesis of ED. In our opinion, these treatment methods could help many ED patients recover fully or partially from ED within the next few decades.

Abstract
Context Erectile dysfunction (ED) following radical prostatectomy is a concern for patients and their partners. Low-intensity extracorporeal shockwave therapy (LI-ESWT) can potentially enhance tissue repair and regeneration. The aim of the current study was to systematically review the literature to assess the role of LI-ESWT in the management of patients with postprostatectomy ED. Evidence acquisition Two authors independently performed a systematic search of the PubMed and Web of Science databases to identify all relevant articles. Non-English reports, case reports, reviews, letters, and editorials were excluded. Risk of bias was assessed according to the GRADE guidelines. Evidence synthesis Nine articles met the inclusion criteria and were included in the qualitative analysis. All the studies included were published between 2015 and 2022 and the majority of them compared phosphodiesterase type 5 inhibitors (PDE5Is) alone versus a combination of LI-ESWT and PDE5Is. Only three studies were randomized controlled trials (RCTs). In general, there is no standardized protocol for LI-ESWT for postprostatectomy ED. In comparisons of LI-ESWT + PDE5Is versus PDE5Is alone, some authors found a statistically significant improvement in erectile function with LI-ESWT + PDE5Is. The starting time for LI-ESWT differed among the studies, ranging from 3 d to 6 mo after surgery. The main limitations of the review are the scarcity of studies, small sample sizes, high risk of bias, and high heterogeneity among studies. Conclusions There is currently limited evidence on the use of LI-ESWT either alone or in combination with PDE5Is in penile rehabilitation protocols after prostatectomy. However, small clinical trials with short follow-up show that LI-ESWT could potentially play a role in the management of postprostatectomy ED in the future. Further RCTs with larger sample sizes are needed. Patient summary Despite limited reports in the literature, low-intensity shockwave therapy after removal of the prostate is a promising noninvasive treatment for dealing with erectile dysfunction after surgery.

Abstract
BACKGROUND Radical prostatectomy (RP) and radiation treatment are standard options for localized prostate cancer. Even though nerve-sparing techniques have been increasingly utilized in RP, erectile dysfunction (ED) due to neuropraxia remains a frequent complication. Erectile function recovery rates after RP remain unsatisfactory, and many men still suffer despite the availability of various therapies. OBJECTIVE This systematic review aims to summarize the current treatments for post-RP-ED, assess the underlying pathological mechanisms, and emphasize promising therapeutic strategies based on the evidence from basic research. METHOD Evaluation and review of articles on the relevant topic published between 2010 and 2021, which are indexed and listed in the PubMed database. RESULTS Phosphodiesterase type 5 inhibitors, intracavernosal and intraurethral injections, vacuum erection devices, pelvic muscle training, and surgical procedures are utilized for penile rehabilitation. Clinical trials evaluating the efficacy of erectogenic drugs in this setting are conflicting and far from being conclusive. The use of androgen deprivation therapy in certain scenarios after RP further exacerbates the already problematic situation and emphasizes the need for effective treatment strategies. CONCLUSION This article is a detailed overview focusing on the pathophysiology and mechanism of the nerve injury developed during RP and a compilation of various strategies to induce cavernous nerve regeneration to improve erectile function (EF). These strategies include stem cell therapy, gene therapy, growth factors, low-intensity extracorporeal shockwave therapy, immunophilins, and various pharmacological approaches that have induced improvements in EF in experimental models of cavernous nerve injury. Many of the mentioned strategies can improve EF following RP if transformed into clinically applicable safe, and effective techniques with reproducible outcomes.

Efficacy of Low-Intensity Extracorporeal Shock Wave Treatment in Erectile Dysfunction following Radical Prostatectomy: A Systematic Review and Meta-Analysis. J Clin Med 2022; 11:jcm11102775. [PMID: 35628901 PMCID: PMC9145026 DOI: 10.3390/jcm11102775] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 04/25/2022] [Accepted: 05/12/2022] [Indexed: 11/23/2022] Open
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
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.

Abstract
UNLABELLED Extracorporeal shock wave therapy (ESWT) is a relatively new branch of physiotherapy. PURPOSE OF THE STUDY Conduct an analytical review of the available literature data on the use of ESWT in oncology. MATERIAL AND METHODS A review was conducted, including data from electronic databases: Scopus, Web of Science, MedLine, World Health Organization, The Cochrane Central Register of Controlled Trials, ScienceDirect, US National Library of Medicine National Institutes of Health, PubMed, Google Scholar, elibrary, CyberLeninka, disserCat. RESULTS AND CONCLUSION The study of ESWT in oncology is carried out in two directions: 1) impact on the tumor with the aim of its disintegration, inhibition of growth, enhancement of the action of radiation and/or chemotherapy; 2) rehabilitation of cancer patients. Shock waves in vitro and in vivo significantly reduce the viability and activate apoptosis of cell lines of osteosarcoma, cancer of the stomach, colon, rectum, bladder, breast, urothelial cancer of the upper urinary tract, adenocarcinoma of the cervix, Burkitt's lymphoma, sarcoma, anaplastic thyroid cancer glands, glioblastoma multiforme. Shock waves also sensitize tumor cells for adjuvant chemotherapy and increase its antitumor activity. The lack of a stimulating effect on a number of malignant tumors in this physical factor makes it possible to conduct ESWT studies in the rehabilitation of cancer patients. The data obtained by a number of authors indicate the clinical efficacy of ESWT in the rehabilitation of patients with erectile dysfunction after radical prostatectomy, with postmastectomy lymphedema of the upper limb, with myofascial pain syndrome after cervical lymph node dissection due to malignant neoplasms of the head and neck, with peripheral polyneuropathy induced by cytostatics. However, in order to develop indications and contraindications for the appointment of ESWT in the rehabilitation of cancer patients, it is not enough just to evaluate its clinical effectiveness; currently absent scientific studies with long-term follow-up of patients who received this method of physiotherapy are needed.

Abstract
Energy-based therapies are novel treatments for erectile dysfunction that are thought to work by stimulation of tissue vasodilation, neoangiogenesis, and so forth. Low-intensity extracorporeal shock wave therapy (Li-ESWT) is the energy-based therapy with the most robust evidence basis demonstrating efficacy and safety. Among this evidence, randomized controlled trials (RCTs) evaluating Li-ESWT have largely been focused on responders to phosphodiesterase-5 inhibitors. Many of these RCTs have limitations including short follow-up durations, inconsistent protocols, and small sample sizes. Until more diverse patient populations are studied and these limitations are addressed, the use of Li-ESWT should remain limited to IRB-approved clinical research trials.

Regenerative technology to restore and preserve erectile function in men following prostate cancer treatment: evidence for penile rehabilitation in the context of prostate cancer survivorship. Ther Adv Urol 2021; 13:17562872211026421.

Abstract
Introduction Erectile dysfunction (ED) following prostate cancer treatment is not uncommon and penile rehabilitation is considered the standard of care in prostate cancer survivorship (PCS), where both patient and his partner desire to maintain and/or recover pre-treatment erectile function (EF). There is a clinical interest in the role of regenerative therapy to restore EF, since existing ED treatments do not always achieve adequate results. Aim To review regenerative therapies for the treatment of ED in the context of PCS. Materials and Methods A review of the existing PubMed literature on low-intensity extracorporeal shockwave therapy (LIESWT), stem cell therapy (SCT), platelet-rich plasma (PRP), gene therapy, and nerve graft/neurorrhaphy in the treatment of ED and penile rehabilitation, was undertaken. Results IESWT promotes neovascularization and neuroprotection in men with ED. While several systematic reviews and meta-analyses showed positive benefits, there is limited published clinical data in men following radical prostatectomy. Cellular-based technology such as SCT and PRP promotes cellular proliferation and the secretion of various growth factors to repair damaged tissues, especially in preclinical studies. However, longer-term clinical outcomes and concerns regarding bioethical and regulatory frameworks need to be addressed. Data on gene therapy in post-prostatectomy ED men are lacking; further clinical studies are required to investigate the optimal use of growth factors and the safest vector delivery system. Conceptually interpositional cavernous nerve grafting and penile re-innervation technique using a somatic-to-autonomic neurorrhaphy are attractive, but issues relating to surgical technique and potential for neural 'regeneration' are questionable. Conclusion In contrast to the existing treatment regime, regenerative ED technology aspires to promote endothelial revascularization and neuro-regeneration. Nevertheless, there remain considerable issues related to these regenerative technologies and techniques, with limited data on longer-term efficacy and safety records. Further research is necessary to define the role of these alternative therapies in the treatment of ED in the context of penile rehabilitation and PCS.

Patient Reported Sexual Function Outcomes in Male Patients Following Open Radical Cystoprostatectomy and Urinary Diversion. Urology 2021; 157:161-167. [PMID: 34298032 DOI: 10.1016/j.urology.2021.07.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 06/23/2021] [Accepted: 07/08/2021] [Indexed: 02/04/2023]
Abstract
OBJECTIVE To report sexual health outcomes in male patients undergoing open radical cystoprostatectomy using a validated questionnaire. MATERIALS AND METHODS Beginning in 2017, male patients were asked to complete a validated questionnaire during scheduled post-cystectomy clinic visits that assessed sexual function using the 5 item International Index of Erectile Function (IIEF-5) and supplemental questions which evaluated libido, orgasm, partner interest, and adequacy of pre-operative counselling. Baseline data and functional outcomes were compared and multivariable analysis performed. RESULTS A total of 134 patients who met inclusion criteria completed the questionnaire. Pre-operative IIEF-5 was available in 78 patients with a median score of 16 (IQR:5-23). In those patients, median age at cystectomy was 68.9 years (IQR:60.2-72.4) and median duration of follow-up was 17.3 months (IQR:6.3-28.7). Median IIEF-5 score at time of survey completion was 1 (IQR:1-11). Increasing age, shorter follow-up duration, insufficient counselling, and absence of partner interest were predictive of lower scores. Younger age, pre-operative erectile function, and neurovascular preservation were predictive of a higher IIEF-5 score on univariate and multivariate analysis. Median libido score was 2 "low" (IQR:1-3) and ability to orgasm was reported by 34 (43.6%) patients. Neurovascular preservation (OR:3.03 95% CI:1.10-8.26, P = .03) and sufficient preoperative counselling (OR:3.078 95% CI:1.17-8.098, P = .02) were associated with preserved ability to orgasm. Libido was influenced by partner interest (OR 11.7, 95% CI:3.793-6.14, P <.0001). CONCLUSION Sexual dysfunction after radical cystoprostatectomy is prevalent with many contributing factors. As such, establishing appropriate expectations and goals during preoperative counseling, performing neurovascular preservation when appropriate, and readily identifying and treating dysfunction in follow-up may improve sexual recovery.

Electronic database searches and manual searches were performed to identify (i) clinical trials or cohort studies evaluating the effectiveness of radial waves in men with erectile dysfunction and (ii) preclinical trials in animal models or cell cultures in which the production of nitric oxide or endothelial growth factor was evaluated. Study quality was assessed, and data were extracted from each study. A narrative synthesis of the results was performed given the high heterogeneity between the selected studies. Main outcomes measures Nitric oxide production, endothelial growth factor expression, and changes in the Erection Hardness Score (EHS) and the International Index of Erectile Function (IIEF) Questionnaire score. Results Four studies in animal models and 1 randomized clinical trial in men with erectile dysfunction and kidney transplantation were identified that met the selection criteria. Preclinical studies in animals suggest that radial waves increase cellular apoptosis in penile tissue, while vascular endothelial growth factor expression increases in brain tissue. In men with erectile dysfunction, no differences were found between radial wave therapy and placebo therapy in the mean IIEF score (15.6 ± 6.1 vs 16.6 ± 5.4 at 1 month after treatment), EHS (2.5 ± 0.85 vs 2.4 ± 0.7 at 1 month after treatment), or penile Doppler parameters. Conclusions No quality evidence was found to support the use of radial waves in humans for the treatment of erectile dysfunction. In animal models and at the cellular level, the results are contradictory. More research is needed. Sandoval-Salinas C, Saffon JP, Corredor HA, et al.

Abstract
Objectives: To review the current evidence of clinical effectiveness of low-intensity extracorporeal shockwave therapy (LI-ESWT) treatment for erectile dysfunction (ED). METHODS A selective database search using Medical Subject Headings (MeSH) terms 'low intensity extracorporeal shock wave therapy' and 'erectile dysfunction' was conducted in accordance with the Preferred Reporting Items for Systemic Reviews and Meta Analyses (PRISMA) guidelines to review the effectiveness of LI-ESWT for ED. We performed a systematic search of publications using the PubMed and Web of Science databases (January 2010-December 2020) for prospective randomised clinical trials (RCTs). The success rate of LI-ESWT associated with ED were recorded and analysed. RESULTS A total of 106 articles were reviewed after searching for the keywords. Overall, 11 RCTs were included in this systematic review. A total of 920 male patients were treated in 11 RCTs. The patients' ages ranged from 18 to 80 years and they had ≥3 months of ED symptoms. Vasculogenic and neurogenic causes were addressed in 81% and 19% of patients, respectively. Of the 920 patients, 348 patients had a statistically significant improvement in their erectile function after LI-ESWT; however, 572 did not have a statistically significant improvement. CONCLUSIONS The present review found that LI-ESWT has a role in ED treatment in laboratory studies, but its role in human clinical trials is still controversial. Further good quality studies need to be conducted to properly assess its true potential in ED treatment.

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
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.

Abstract
Extracorporeal treatment with low intensity shock-wave therapy (LI-ESWT) is a recently introduced non-invasive method which purposes the restoration of the pathophysiological alterations at the base of vasculogenic ED in male patients. The evidence in favour of the neoangiogenic potential of this treatment derived from in vitro studies and on animal models. The purpose of this study, in which the Power Doppler method was applied, is to demonstrate 'objectively' the real efficacy of LI-ESWT at the level of the microcirculation of the corpora cavernosa (neoangiogenesis) in patients affected by vasculogenic ED. Data from this study show, for the first time, that LI-ESWT treatment promotes neovascularisation of the functional arteries in patients affected by vasculogenic ED.

Abstract
Erectile Dysfunction (ED) is the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance, causing tremendous effects on both patients and their partners. The pathophysiology of ED remains a labyrinth. The underlying mechanisms of ED may be vasculogenic, neurogenic, anatomical, hormonal, drug-induced and/or psychogenic. Neurogenic ED consists of a large cohort of ED, accounting for about 10% to 19% of all cases. Its diversity does not allow an in-depth clarification of all the underlying mechanisms nor a “one size fits all” therapeutical approach. In this review, we focus on neurogenic causes of ED, trying to elucidate the mechanisms that lie beneath it and how we manage these patients.

Abstract
Erectile dysfunction (ED) is both a common and complex disease process. Existing ED treatments do not always achieve adequate results. There is clinical interest in employing regenerative therapies, including low-intensity extracorporeal shockwave therapy (Li-ESWT), platelet rich plasma (PRP), and stem cell therapy (SCT), in the treatment of ED as adjunct or alternative treatments. Here, we present evidence for emerging shockwave- and cell-based regenerative therapies for the treatment of ED following a thorough review of the existing PubMed literature pertaining to Li-ESWT, PRP, and SCT in relation to the treatment of ED. Li-ESWT causes microtrauma in tissue that hypothetically upregulates angiogenesis and recruits stem cells. Several large-scale systematic reviews and meta-analyses have reported that Li-ESWT improved ED in humans. Additionally, evidence has commenced to show that Li-ESWT may be effective against two recognized and complex etiologies of ED: diabetic and neurogenic. PRP delivers an autologous sample rich in growth factors to damaged tissue. Animal model studies have demonstrated improved erectile function recovery as well as preservation of cavernous nerve axons. Studies with PRP in humans are limited. SCT utilizes the regenerative potential of stem cells for healing of damaged tissue. In the treatment of ED, SCT has been used in the setting of diabetic and post-prostatectomy ED. Results of human studies are varied, although SCT treatments did result in increased erectile rigidity with some patients recovering the ability to achieve penetration. While these regenerative therapies show potential to augment the current treatment regimen for ED, there is a paucity of evidence to support the safety and efficacy of these treatments. Further research is necessary to define the role of these alternative therapies in the treatment of ED.

Low-intensity extracorporeal shockwave therapy among urologist practitioners: how the opinion of urologists changed between 2016 and 2019. Int J Impot Res 2020; 33:839-843. [PMID: 32826969 DOI: 10.1038/s41443-020-00347-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Revised: 08/03/2020] [Accepted: 08/13/2020] [Indexed: 11/08/2022]
Abstract
Over the past few years, an increase use of low-intensity shockwave therapy (LISWT) for the treatment of erectile dysfunction (ED) has been observed. However, many controversies in the scientific literature about its efficacy still exist. We aimed to investigate changes in the pattern of usage and attitudes toward LISWT for ED among experts over the last years. A dedicated online survey was sent to delegates at the Congress for the EAU Section of Andrological Urology (ESAU) in Prague from 31st October to 1st November 2019. The survey captured demographic data, professional background, and the experience and personal knowledge about LISWT. The results were compared with a previous survey conducted in 2016 and investigating the same topics in order to assess changes in the knowledge and opinion on LISWT over time. Overall, 172 and 192 questionnaires were available from 2019 and 2016, respectively. Participants in the 2019 survey were 80 (45.7%) urologists, 52 (29.7%) uro-andrologists, and 34 (19.4%) residents in urology, from 30 different countries. Compared to the past, we observed an increase of respondents who were familiar with LISWT (75 vs. 95%; p < 0.0001) and who performed LISWT in their routine practice (38% in 2019 vs. 14% in 2016; p < 0.0001). Conversely, no changes in terms of overall perception of treatment efficacy were registered over time (68% in 2019 vs. 72% in 2016 considered LISWT as an effective treatment, respectively (p = 0.5)). An increased proportion of physicians had suggested a wider application of LISWT, and some even advocated its use in nonvasculogenic ED (33% in 2019 vs. 5.9% in 2016; p < 0.0001). The awareness and clinical application of LISWT for ED have increased over time, despite the lack of robust evidence in terms of effectiveness. Further research on the benefit of LISWT is needed to guide physicians in the therapeutic management of ED patients.

Abstract
BACKGROUND Erectile dysfunction (ED) after radical prostatectomy (RP) still represents a major issue. Considering the benefits recently described regarding the application of low-intensity extracorporeal shockwave therapy (LiESWT) in vasculogenic ED, questions arise about its role in the scenario of penile rehabilitation. AIM To compare the early introduction of phosphodiesterase-5 inhibitor (PDE5i) with a combination therapy enrolling both early PDE5i use and LiESWT in patients submitted to RP. METHODS This study is a randomized clinical trial, open-label, with 2 parallel arms and an allocation ratio of 1:1. The study was registered in ReBEC (ensaiosclinicos.gov.br) Trial: RBR-85HGCG. Both arms started tadalafil at a dose of 5 mg/day right after the removal of the transurethral catheter, and the experimental group received 2,400 shocks/session-week distributed on 4 different penile regions. The full treatment consisted of 19,200 impulses across 8 weeks. OUTCOMES The primary clincal end point was ≥4-point difference favoring the experimental group considering the mean International Index of Erectile Function short form (IIEF-5) at last follow-up. Any statistical difference in the IIEF-5 score between the arms was stated as the primary statistical end point. RESULTS Between September 25, 2017, and December 3, 2018, 92 men were enrolled in the study. At last follow-up, we assessed 77 patients, 41 in the control group and 36 in the intervention group. A difference between groups was detected when accessing the final median IIEF-5 score (12.0 vs 10.0; P = .006). However, the primary clinical endpoint considering a difference ≥4-point between the arms has not been reached. When performing an exploratory analysis comparing the proportion of those individuals with an IIEF-5 score ≥17, no difference between groups was noted (17.1% vs 22.2%; P = .57). CLINICAL IMPLICATIONS So far, the benefits arising from LiESWT for penile rehabilitation after RP have been uncertain. STRENGTHS & LIMITATIONS This is the first trial assessing the role of LiESWT on erectile function after RP. Our study protocol included only one session per week for the experimental group, raising a query if a more intensive application could achieve better results once a statistically significant difference was found between groups. We discontinue the PDE5i use at the last session, which may have interfered in the penile vascular rehabilitation, maybe compromising the results too. CONCLUSION After therapy with 19,200 impulses therapy across 8 weeks, we found an improvement of the IIEF-5 score, but it was not enough to be considered clinically significant. More studies are warranted before any recommendation on this topic. Baccaglini W, Pazeto CL, Corrêa Barros EA, et al.

Abstract
INTRODUCTION Low-intensity extracorporeal shock wave therapy (Li-ESWT) is a new treatment modality for erectile dysfunction (ED). Our aim was to evaluate the treatment outcome of Li-ESWT for ED in single-blind, placebo controlled, randomized clinical trial. METHODS Sixty patients were randomized into 2 age-matched groups: Group A - treatment and Group B - placebo. Treatment consisted of 4 sessions on the PiezoWave2 unit (R. Wolf and ELvation Medical). Effectiveness was assessed according to the International Index of Erectile Function 5 (IIEF-5), Erectile Hardness Score (EHS), questions 2 and 3 of the Sexual Encounter Profile (SEP 2, SEP 3), and Global Assessment Question (GAQ) scores at baseline and 4 and 12 weeks after treatment. We evaluated patient's and partner's subjective satisfaction. RESULTS A statistically significant difference between the groups was found at 4 and 12 weeks after treatment with regard to the quality of erection as measured by the IIEF-5 (p = 0.049 and p < 0.001, respectively), the EHS after week 12 (p < 0.001), an increase in the EHS after 4 and 12 weeks (p = 0.030 and p < 0.001, respectively), after 12 weeks in GAQ (p < 0.001), SEP 2 (p = 0.05), SEP 3 (p < 0.001), and patient's satisfaction (p < 0.001) and partner's satisfaction (p < 0.001). CONCLUSIONS The randomized single-blind study confirms that Li-ESWT significantly improves erectile function.

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

Abstract
Low-intensity extracorporeal shockwave therapy (LI-ESWT) to the penis has recently emerged as novel therapeutic option in the treatment of erectile dysfunction (ED). Randomized-controlled studies investigating the effect of this new treatment modality revealed promising results in men with vasculogenic ED. However, the efficacy of LI-ESWT in men who develop ED following radical prostatectomy (RP) remains obscure due to the exclusion of this group in nearly all clinical trials. In this review, the authors synthesize the findings from available preclinical and clinical studies that examine the potential utility of LI-ESWT in men with post-RP ED.

Clinical studies on low intensity extracorporeal shockwave therapy for erectile dysfunction: a systematic review and meta-analysis of randomised controlled trials. Int J Impot Res 2019; 31:177-194. [PMID: 30664671 DOI: 10.1038/s41443-019-0117-z] [Citation(s) in RCA: 49] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2018] [Revised: 01/07/2019] [Accepted: 01/10/2019] [Indexed: 01/25/2023]
Abstract
The efficacy of low intensity extracorporeal shock wave therapy (LI-ESWT) for erectile dysfunction (ED) has received hard criticism and recently published meta-analyses were not able to provide further insights, nor specific recommendations. The aim of this systematic review and meta-analysis is to evaluate the efficacy of LI-ESWT for ED, identify the ideal treatment population and treatment protocol, and provide recommendations for future research in the field. A systematic research for relevant clinical studies published from January 2010 to September 2018 was performed, using the following databases: Medline, Embase, The Cochrane Library, Scopus, and Web of Science. Only clinical studies that investigated the efficacy of LI-ESWT for ED only, and reported primary outcomes using IIEF-EF scores/questionnaires were included. Both, randomised controlled trials (RCTs) and cohort studies were included, but the meta-analysis was performed only for sham-controlled RCTs. Ten RCTs including 873 patients were selected for the meta-analysis. Pooling data of these studies showed that LI-ESWT could significantly improve erectile function in men with ED regarding both patient-subjective outcomes (IIEF-EF: +3.97; 95% CI [2.09-5.84]; p < 0.0001, EHS ≥ 3: OR: 4.35; 95% CI [1.82-10.37]; p = 0.0009) and patient-objective outcomes (peak systolic velocity: +4.12; 95% CI [2.30-5.94]; p < 0.00001). In conclusion, the present meta-analysis provided results showing that LI-ESWT significantly improves erectile function in patients with vasculogenic ED.
