Abstract
To explore the effect of leukocyte-platelet-rich fibrin (L-PRF) on promoting wound healing in diabetic foot ulcers. A total of 42 patients with diabetic foot ulcers at our hospital from January 2017 to July 2020 were retrospectively analyzed. A control group and a PRF group were established. The two groups of patients underwent debridement. In the platelet-rich fibrin (PRF) group, autologous L-PRF was used to cover ulcer wounds. One time each week, Vaseline gauze was used to cover the ulcer wounds. In contrast, the control group was treated with the external application of mupirocin ointment and recombinant human epidermal growth factor gel (yeast). Two times each week, the sterile Vaseline gauze was covered with a bandage. Both groups were treated for 5 weeks. The wound recovery of the two groups was observed. During the early stage of treatment (first and second weeks) for diabetic foot ulcers, the wound healing rate was significantly better with L-PRF treatment than traditional treatment. For later-stage treatment (third to fifth weeks), the overall cure rate was higher with L-PRF than the traditional treatment method. L-PRF can effectively promote wound healing in diabetic foot ulcers.

Abstract
PURPOSE Platelet-rich plasma (PRP) as a regenerative therapy has gained interest in the field of andrology for the treatment of erectile dysfunction (ED) and Peyronie's disease (PD). This systematic review aims to critically evaluate the current evidence on the use of PRP for these conditions. METHODS We performed a systematic literature search according to the PRISMA guidelines using PubMed and Scopus databases in December 2023. Studies were included if they evaluated the effect of PRP therapy for ED or PD in humans. RESULTS We identified 164 articles, 17 of which were included, consisting of 11 studies on ED, 5 studies on PD, and 1 study on both. We included four randomized controlled trials, 11 prospective cohort studies, and three retrospective cohort studies including a total of 1099 patients. The studies on ED and PD generally showed small to moderate benefits with mild and transient side effects and no major adverse events were reported. General limitations included variations in PRP protocols, small sample sizes, short follow-up periods, and lack of control groups except in the three randomized trials on ED and the one on PD. CONCLUSION The literature on PRP therapy in andrology is limited and difficult to interpret due to variations in protocols and methodological drawbacks. Further research is necessary to determine the optimal preparation and treatment protocols for PRP therapy and clarify its effectiveness in andrology.

Ural ÜM. The effect of injectable platelet rich fibrin as a nonsurgical treatment of the female stress urinary incontinence. Arch Gynecol Obstet 2024; 309:2229-2236. [PMID: 38424182 DOI: 10.1007/s00404-024-07431-3] [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: 10/24/2023] [Accepted: 02/12/2024] [Indexed: 03/02/2024]
Abstract
PURPOSE The complications of surgical treatments of stress urinary incontinence have led to the search for less invasive and safer treatment procedures. We aimed to investigate the efficacy of locally administered injectable platelet-rich fibrin (i-PRF), an autologous material that plays an important role in tissue regeneration, in women with stress urinary incontinence. METHODS Thirty-four women were included in this prospective, single-center, and interventional study, suffering from stress urinary incontinence refractory to conservative treatment. Three consecutive i-PRF injections were applied to the mid-urethra localization at anterior vaginal wall with an interval of 1 month. ICIQ-SF, UDI-6, IIQ-7 and POPDI-6 questionnaires were used to measure pre‑treatment, 1 month and 6 months post‑treatment symptom severity and the clinical outcomes were recorded. RESULTS The mean age of the patients was 51.5 ± 9.8 years. ICIQ-SF, UDI-6, IIQ-7 and POPDI-6 questionnaires results revealed significant clinical improvement of stress urinary incontinence severity afer the administration of i-PRF (p < 0.001). The results at 1 and 6 months after treatment did not change statistically significantly. CONCLUSION This study demonstrated that locally administiration of i-PRF is efective in relieving SUI symptoms with high success rates without any adverse effects reported. i-PRF injection may have the potential to be a novel, minimally invasive, and low-risk procedure, that could be an alternative and simple treatment modality to surgery for female patients with stress urinary incontinence. Additionally, it may create new avenues for research on therapeutic implementation of i-PRF.

Abstract
The objective of this study is to evaluate the safety and feasibility of the combined simultaneous percutaneous needle tunneling coupled with injection of platelet-rich plasma in the outpatient department for the treatment of Peyronie's disease. This prospective, non-randomized, cohort and preliminary study included patients who underwent this procedure from November 2020 to July 2022. The main outcome was an improvement in penile curvature. Fifty-four patients were enrolled and underwent 6 sessions under local anesthesia followed by vacuum therapy for the treatment of Peyronie's disease in our outpatient unit. The amendment of the curvature angle was significant with a median correction percentage of -44.40% interquartile range (-66.70 to (-39.70)), [p-value = 0.001, 95% CI (-29.76 to (-18.02)), paired Student's t-test]. The median pre-treatment curvature angle was 45° (40-75), and the median post-treatment was 30° (20-40). The median score for pain during the procedure was 3 (0-4.25) according to a 10-point visual analogic scale. After two hours, 20.37% of patients still had pain but none required any pain medication. 50% of patients had a minor hematoma and 75.93% patients reported penile ecchymosis. A single patient reported an injection site skin infection. In our experience percutaneous needle tunneling with platelet-rich plasma injections for Peyronie's disease in the outpatient setting is a safe, effective, and feasible treatment of penile deformity for PD.

[PMID: 38196188 DOI: 10.1093/sxmrev/qead055] [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: 06/27/2023] [Revised: 09/25/2023] [Accepted: 10/09/2023] [Indexed: 01/11/2024]
Abstract
INTRODUCTION Erectile dysfunction (ED) represents the major cause of male sexual dysfunction, which is often associated with obesity, diabetes mellitus, atherosclerotic cardiovascular disease, and cigarette smoking. Peyronie's disease is a chronic disorder associated with irreversible fibrotic damage of the tunica albuginea leading to ED, painful erection, coital disturbance, and physical and social complaints. Both conditions are characterized by chronic inflammation, oxidative stress, and significant changes in intracavernous hydrodynamics. In this scenario, oxidized lipoproteins, M1-polarized macrophages, proinflammatory cytokines (such as the tumor necrosis factor α), endothelial nitric oxide synthase, penile smooth muscle cells, and toll-like receptors represent the main triggers of the inflammatory process in ED. Phosphodiesterase-5 inhibitors are the most common treatment for ED. This treatment is used intermittently, as it is conceived as a symptomatic and not curative therapy. Moreover, not all patients respond to phosphodiesterase-5 inhibitors (35%-85%), particularly those with dysmetabolic phenotypes. Additional or alternative treatments are therefore desirable, mostly in refractory cases. OBJECTIVES In this review, we describe the immune-mediated pathogenesis of ED and Peyronie's disease (PD). In our literature search we placed particular emphasis on potentially practical therapeutic approaches, including natural products (such as polyphenols), due to their anti-inflammatory and antioxidant activities, stem cell therapy, and platelet-derived preparations. METHODS We searched PubMed/MEDLINE, Web of Science, Scopus, Cochrane Library, Google Scholar, and institutional websites. Original studies, narrative reviews, systematic reviews, and meta-analyses written in English were searched, screened, and selected. RESULTS In animal models of ED and PD, therapeutic approaches, including anti-inflammatory and antioxidant agents, stem cell therapy, and platelet-derived preparations, have provided positive results, including improved penile function, reduced inflammation and oxidative stress, and promotion of tissue repair. However, clinical evidence of improvement in human patients is still insufficient. CONCLUSION Promising results for treating ED and PD have been shown in preclinical and pilot clinical studies, but specific clinical trials are needed to validate the efficacy of these therapeutic approaches in men with ED.

Autologous platelet rich plasma (A-PRP) combined with pelvic floor muscle training for the treatment of female stress urinary incontinence (SUI): A randomized control clinical trial. Neurourol Urodyn 2024; 43:342-353. [PMID: 38108468 DOI: 10.1002/nau.25365] [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: 09/21/2023] [Revised: 11/26/2023] [Accepted: 12/01/2023] [Indexed: 12/19/2023]
Abstract
IMPORTANCE Autologous platelet-rich plasma (A-PRP) injection is a novel intervention for stress urinary incontinence (SUI) in women. However, no Phase II clinical trial has compared the outcomes of A-PRP injection combined with pelvic floor muscle training (PFMT) with those of PFMT alone in these women. OBJECTIVE The primary aim was to compare the efficacy of A-PRP + PFMT versus PFMT alone in women with SUI. The secondary aim was to determine any adverse effects of A-PRP injection. DESIGN Randomized clinical trial, single-blind assessment. SETTING Urogynecology clinic at a tertiary medical center. PARTICIPANTS Women with previously untreated SUI. Women in whom there was any suspicion of urgency, those with an Overactive Bladder Symptoms Score of ≥1, and those with obesity, pelvic organ prolapse, thrombocytopenia, or coagulopathy were excluded. INTERVENTIONS Two injections of A-PRP were administered with a 1-month interval between injections in the A-PRP injection + PFMT group. Both groups received PFMT. MAIN OUTCOMES AND MEASURES The primary outcome was determined using the 1-h pad weight test (PWT). Secondary outcomes were measured using the Incontinence Quality of Life Questionnaire, item 11 on the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms questionnaire, Patient Global Impression of Improvement, and the percentage subjective improvement score. RESULTS Data for 60 study participants were available for analysis (A-PRP + PFMT group, n = 31; PFMT group, n = 29). The 1-h PWT decreased significantly in the A-PRP + PFMT group but only slightly in the PFMT group at the 5-month follow-up. There was a statistically significant between-group difference in the 1-h pad weight of about 8 g in favor of the A-PRP + PFMT group. A statistically significant difference in symptoms of SUI measured by the questionnaires was found between the A-PRP + PFMT group and the PFMT group at the 2- and 5-month follow-up assessments. There were no reports of adverse events following injection of A-PRP. CONCLUSIONS AND RELEVANCE A-PRP + PFMT could be a treatment option for women with SUI. Large Phase III randomized controlled trials are required to confirm our findings.

Abstract
INTRODUCTION Intra-lesional injections of collagenase (Xiapex®) were the only non-invasive treatment option for Peyronie's disease (PD), until their withdrawal from the European market. OBJECTIVE To evaluate the feasibility, efficacy, and safety of a combined treatment of percutaneous needle tunnelling (PNT) with penile modelling (PM) and the injection of platelet-rich plasma (PRP) under general anesthesia in the treatment of PD. PATIENTS AND METHOD A prospective case series study included patients with PD in a stable phase who underwent this procedure between March 2020 and January 2023. The main outcome was an improvement in curvature. RESULT Thirty-six patients underwent this novel approach for the treatment of PD. The pretreatment mean±standard deviation (SD) curvature degree was 57.5±20.61° (range 20-90°). After the protocol, the mean curvature degree was 40.86±25.13° (range 0-90°). The curvature angle improved significantly (P=0.0001), with a mean improvement difference of 16.85±14.81° (range 0-50°) and a mean improvement percentage of 47.7±40.29% (range 0-100%). CONCLUSION Our preliminary experience suggests that PNT and PRP injections with PM are effective and safe for the treatment of penile deformity of PD. LEVEL OF EVIDENCE 4: case series study.

Abstract
The skin's recognised functions may undergo physiological alterations due to ageing, manifesting as varying degrees of facial wrinkles, diminished tautness, density, and volume. Additionally, these functions can be disrupted (patho)physiologically through various physical and chemical injuries, including surgical trauma, accidents, or chronic conditions like ulcers associated with diabetes mellitus, venous insufficiency, or obesity. Advancements in therapeutic interventions that boost the skin's innate regenerative abilities could significantly enhance patient care protocols. The application of Platelet-Rich Plasma (PRP) is widely recognized for its aesthetic and functional benefits to the skin. Yet, the endorsement of PRP's advantages often borders on the dogmatic, with its efficacy commonly ascribed solely to the activation of fibroblasts by the factors contained within platelet granules. PRP therapy is a cornerstone of regenerative medicine which involves the autologous delivery of conditioned plasma enriched by platelets. This is achieved by centrifugation, removing erythrocytes while retaining platelets and their granules. Despite its widespread use, the precise sequences of cellular activation, the specific cellular players, and the molecular machinery that drive PRP-facilitated healing are still enigmatic. There is still a paucity of definitive and robust studies elucidating these mechanisms. In recent years, telocytes (TCs)-a unique dermal cell population-have shown promising potential for tissue regeneration in various organs, including the dermis. TCs' participation in neo-angiogenesis, akin to that attributed to PRP, and their role in tissue remodelling and repair processes within the interstitia of several organs (including the dermis), offer intriguing insights. Their potential to contribute to, or possibly orchestrate, the skin regeneration process following PRP treatment has elicited considerable interest. Therefore, pursuing a comprehensive understanding of the cellular and molecular mechanisms at work, particularly those involving TCs, their temporal involvement in structural recovery following injury, and the interconnected biological events in skin wound healing and regeneration represents a compelling field of study.

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
INTRODUCTION Erectile dysfunction (ED) is the inability to achieve or maintain erection for satisfactory sexual performance. ED drastically reduces the quality of life for men and their partners and is commonly linked to comorbid conditions such as diabetes and cardiovascular disease. As a result, clinicians and researchers are working to improve treatments for ED. Current guideline-approved ED treatments include oral phosphodiesterase type 5 inhibitors, intraurethral alprostadil, penile intracavernosal injections, and penile prosthesis surgery. Today, there is increasing interest in restorative therapies such as intracavernosal platelet-rich plasma (PRP) for the management of ED. OBJECTIVES This narrative review describes the current trials investigating intracavernosal PRP for ED and proposes future directions to increase the strength of evidence to support use of PRP in this population. METHODS A comprehensive literature search of PubMed, Science Direct, and Scopus was performed to identify all randomized clinical trials using PRP for the treatment of ED. RESULTS We identified 4 randomized clinical trials investigating the safety and efficacy of PRP for ED. We found significant heterogeneity among study protocols, including collection of PRP, dosing of PRP, and follow-up. CONCLUSION While intracavernosal PRP is considered safe, its efficacy for the management of ED remains unknown due to variability among clinical trials.

Abstract
INTRODUCTION There has been tremendous growth in regenerative medicine during the last decade. For erectile dysfunction (ED), after the inclusion of low-intensity shockwave therapy as a treatment modality for ED management by the European Association of Urology sexual health guidelines, intracavernosal injection of platelet-rich plasma (PRP) has gained popularity between urologists and patients as a novel ED therapeutic modality with initial promising results. However, limited clinical data exist regarding efficacy and safety in patients with ED. Furthermore, despite numerous preclinical studies in other tissues and organs, the mechanism of action for restoring erectile function remains undetermined. OBJECTIVES This systematic review aims to present the current status of preclinical and clinical evidence regarding the use of PRP as treatment option for ED. METHODS A systematic literature search was conducted using PubMed, Cochrane, and ScienceDirect databases, until February 2023 for studies exploring the effect of PRP on ED. RESULTS We identified 517 articles, 23 of which were included in this review. These were 7 preclinical (of which 1 was a comparative trial and 6 were placebo-controlled randomized controlled trials) and 16 clinical studies (of which 1 was a comparative trial, 5 were randomized trials, and 2 were placebo-controlled randomized controlled trials). Preclinical data support the regenerative role of PRP in erectile tissue, in accordance with existing evidence in other tissues. Randomized clinical studies, as well as the first 2 available randomized, placebo-controlled clinical trials, showed promising efficacy and a lack of any adverse events. CONCLUSION As PRP for ED is widely used worldwide, there is an urgent need for high-quality studies with long-term follow-up. Standardization of research protocols, especially on the quality of PRP preparation, is also needed.

Abstract
PURPOSE We assessed the safety and efficacy of 2 injections of platelet-rich plasma for treating mild to moderate erectile dysfunction by conducting a prospective, randomized, double-blind, placebo-controlled clinical trial. MATERIALS AND METHODS Men with mild to moderate erectile dysfunction (International Index of Erectile Function scores 11-25) were randomized to receive either 2 injections of platelet-rich plasma or placebo separated by 1 month. Primary outcome was percentage of men meeting minimum clinically important difference at 1 month after the second injection. Secondary outcomes were change in International Index of Erectile Function at 1, 3, and 6 months, and changes in penile vascular parameters and adverse events at 6 months. RESULTS We randomized 61 men: 28 into platelet-rich plasma and 33 into placebo. There was no difference between groups in percentage of men meeting minimum clinically important difference at 1 month: 14 (58.3%) in platelet-rich plasma vs 15 (53.6%) in placebo (P = .730). Mean International Index of Erectile Function-Erectile Function domain changed from 17.4 (95% CI 15.8-19.0) to 21 (17.9-24.0) at 1 month in men receiving platelet-rich plasma, vs 18.6 (17.3-19.8) to 21.6 (19.1-24.1) in the placebo group; however, there was no significant difference between groups (P = .756). There were no major adverse events and only 1 minor adverse event in each group. There were no changes in penile Doppler parameters from baseline to 6 months. CONCLUSIONS The results of our prospective, double-blind, randomized, placebo-controlled clinical trial suggest that 2 injections of intracavernosal platelet-rich plasma separated by 1 month in men with mild to moderate erectile dysfunction is safe, but we found no difference in efficacy between platelet-rich plasma and placebo.

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
The clinical landscape of Peyronie's disease is everchanging. There has been growing interest in non-invasive therapeutic options that could assist patients with achieving a meaningful reduction in penile curvature without surgical intervention. These therapies are wide-ranging in terms of their mechanisms of action, efficacies, and short- and long-term safety profiles. Recently, an abundance of outcomes literature on longstanding and novel non-surgical treatment modalities has been published. For sexual medicine providers hoping to offer patients the most up-to-date and evidence-based treatments for the management of Peyronie's disease, it can be challenging to gain a thorough understanding of this body of literature. In this clinical management review, the workup and current theories on the pathophysiology of Peyronie's disease are reviewed, and the most recent outcomes data on the currently available non-surgical treatment modalities are presented. With an accurate understanding of the current landscape of Peyronie's disease treatment, sexual health providers will be able to better evaluate and engage in evidence-based shared decision-making with their patients.

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

Abstract
OBJECTIVE To characterize direct-to-consumer (DTC) men's health clinics by reviewing their online content. Increasing numbers of patients are seeking treatment for erectile dysfunction (ED) and hypogonadism from DTC "men's health" clinics. Treatments are often used off-label, with lack of transparency of provider credentials and qualifications. METHODS We identified DTC Men's Health Clinics in the United States by internet search by state using the terms, "Men's Health Clinic," and "Low T Center." All stand-alone clinics were reviewed. RESULTS Two hundred and twenty-three clinics were reviewed, with 147 (65.9%) offered ED treatments and 196 (87.9%) offering testosterone replacement, and 120 (53.8%) offering both ED treatment and testosterone replacement. Of those clinics offering ED treatments, 93 (63.3%) advertised shockwave therapy and 84 (57.1%) PRP therapy. There were 56 (38%) who offered shockwave therapy and PRP. ICI was significantly more likely to be offered if there was a urologist on staff (p <.001). Clinic providers represented 20 different medical and alternative medicine specialties. Internal medicine was most common (17.4%), followed by family medicine (11.1%). A nonphysician (nurse practitioner or physician assistant) was listed as the primary provider in 10 clinics (4.5%) and 45 clinics (20.1%) did not list their providers. Urologists were listed as the primary provider in 10.3% of clinics. A naturopathic provider was listed as a staff member in 22 (11.6%) of clinics. CONCLUSION There is significant heterogeneity and misinformation available to the public regarding men's health. Familiarity with and insight into practice patterns of "men's health" clinics will help provide informed patient care and counseling.

Abstract
OBJECTIVE To evaluate the safety and efficacy of platelet rich plasma (PRP) injections as a therapeutic modality for mild to moderate erectile dysfunction. METHODS A placebo-controlled study of 100 cases with mild to moderate erectile dysfunction. Participants were allocated to 2 groups; the PRP group received 3 injections (3 mL each corpus) and the interval between injections was 15 days, while the Placebo (Saline) group received 6 mL saline injected intracavernous. Postinjection follow-up lasted 6 months. RESULTS Compared to the placebo group, the PRP group demonstrated a significant improvement at the 1 and 3 months follow-up that slightly dropped at the 6 months follow-up (P <.001). The improvement was evident in the duplex parameters, International Index of Erectile Function Erectile Function (IIEF-EF), SEP Q2, and 3. At 1-month post-treatment follow-up (76%) patients in the PRP group had an improved IIEF-EF as they attained a minimal clinically important difference compared to (18%) in the saline group. At the 3-months post-treatment follow-up, (72%) patients achieved a minimal clinically important difference in the PRP group vs (16%) in saline group then dropped to (70%) in the PRP group vs (16%) in saline group at the 6-months post-treatment follow up. Patients' overall and intercourse satisfaction levels were higher in the PRP group than the placebo group as demonstrated with the higher IIEF score Q6, 7, 8, and IIEF score Q13, 14 respectively with the maximum improvement reported at the 3 months follow-up. No reports of plaque formation, subcutaneous bruising, or any other major side effects among participants. CONCLUSION PRP is a safe and promising method for the improvement of mild to moderate erectile dysfunction.

Abstract
PURPOSE OF REVIEW Our objective is to review the currently available literature on the use of platelet-rich plasma (PRP) in patients with pelvic floor disorders and to critically appraise the latest evidence on the safety and efficacy of the PRP application. RECENT FINDINGS The evidence on the use of PRP for the treatment of stress urinary incontinence (SUI) appears promising, although limited to case series, case reports and animal studies. PRP has also been proposed to enhance the surgical outcomes of pelvic organ prolapse (POP) by native tissue repair with promising success rates. The application of PRP in other PFDs including vaginal fistulas, genitourinary syndrome of menopause (GSM), mesh exposure and lichen sclerosus has been also associated with beneficial outcomes and a favorable safety profile. SUMMARY The currently available literature indicates that PRP could have a beneficial effect as a single or adjuvant treatment in patients with SUI, POP, GSM, vaginal fistula and genital lichen sclerosus with minimal adverse events. However, valid evidence is still lacking and further well-designed studies are warranted in the field to confirm the validity of the so far reported outcomes.

Abstract
Objectives The objective of our study is to discover and evaluate the effects of repeated intralesional injections inside the tunica albuginea of platelet-rich plasma (PRP) in the treatment of Peyronie's disease (PD). Methods As part of a prospective study over 12 months from February 2020 until February 2021, on Sixty-five patients with Peyronie's disease, and penile curvature between 25 and 45°. Patients were stratified into two groups, the first with a curvature between 25 and 35° and the second between 35 and 45°. Gathered data included patient-demographics, Injection technique, outcomes: both quantitative (curvature assessments) and qualitative (state of erectile function, pain during intercourse), and complications. Results Patients in both groups received an average of 6.1 injections of PRP during the study period. Angulation was significantly improved in both groups an average final improvement of 16.88° (SD = 3.35) (p < 0.001) in the first group and 17.27° (SD = 4.22) (p < 0.001) in the second group. Pain during sex decreased from 70.7% to 34.25%, and 55.5% of patients had easier sexual intercourse. Conclusions The positive results of our series of treatment for Peyronie's disease by injection of platelet-rich plasma are encouraging both methodologically (simplicity) and clinical (safety and efficacy) as well as patient satisfaction.

Abstract
INTRODUCTION Platelet-rich plasma (PRP) injections are increasingly proposed for the treatment of Peyronie's disease since the discontinuation of Xiapex® despite poorly understood results. OBJECTIVES Evaluation of the tolerance and efficacy of intra-plate PRP injections in patients with Peyronie's disease. METHODS Three intra-plate injections of PRP were performed 15 days apart in 17 patients with Peyronie's disease. The Peyronie's Disease Questionnaire (PDQ) and the measurement of the angle of curvature of the erect penis were assessed before treatment and then 1, 3 and 6 months after treatment. Erectile function was assessed by different questionnaires (IIEF-EF, EHS, SEP, sexual discomfort score). RESULTS No side effects were noted during the study period. Three months after treatment, all three PDQ domains were significantly improved (P=0.002; P=0.015; P=0.017 respectively). The angle of curvature of the penis was significantly decreased by 11.8° with a mean angle of 40.4° before treatment and 28.6° after (P=0.007). The IIEF-EF score was significantly improved after treatment (mean preoperative value: 10.67) with a gain of 5 points at months 1 and 6 (P=0.01 and P=0.036 respectively) and 7 points at month 3 (P=0.04). CONCLUSION Our initial experience suggests that PRP injections for Peyronie's disease are safe. Although the limited data is suggestive of efficacy, a placebo control will be required for confirmation.

Eur J Obstet Gynecol Reprod Biol 2022; 278:38-44. [PMID: 36113285 DOI: 10.1016/j.ejogrb.2022.08.028] [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: 02/19/2022] [Revised: 08/23/2022] [Accepted: 08/30/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVES To assess the feasibility and the safety of treating female stress urinary incontinence (SUI) with suburethral implantation of a mixture of the stromal vascular fraction from adipose tissue and leukocyte-and platelet-rich-fibrin. METHODS Patients with SUI were treated with a mixture of stromal vascular fraction and leukocyte-and platelet-rich fibrin. The stromal vascular fraction was obtained from enzymatic digestion of autologous adipose-tissue and added to an leukocyte-and platelet-rich-fibrin membrane. The mixture was transvaginally implanted into the suburethral area. A fraction of the Stromal vascular fraction sample was used for cellular characterization. Patients were followed for 9 months. Every 3 months, the patients were clinically evaluated with a cough- stress test and a validated-questionnaire. An MRI was performed preoperatively and 3 months after the procedure to assess tissue changes. RESULTS Ten patients received the surgical procedure. The validated-questionnaire revealed a subjective SUI improvement in nine patients 3 months after the operation and in seven patients 9 months after the operation. Eight, six, and four patients achieved a negative cough-stress test 3, 6 and 9 months post-injection, respectively. Flow cytometric analysis of stromal vascular fraction cell phenotypes revealed predominantly mesenchymal and endothelial cell heterogeneity. In total, we injected 0,18 × 106 to 13,6 × 106 cells. No adverse events were observed peri- or postoperatively. CONCLUSION These preliminary results suggest that the suburethral implantation of a combination of SVF and l-PRF is a feasible and safe modality for treating female SUI. However, evidence is lacking and further research are needed to clarify the respective roles of SVF and l-PRF in female SUI treatment.

Abstract
Erectile dysfunction (ED) is one of the commonest disorders in adult males and affects 12–19% of men of reproductive age. Only few studies have evaluated the impact of ED on men and couples with infertility—these studies report higher rates of ED in this sub-group of men compared to the general population, with the prevalence of ED in men diagnosed with male infertility ranging from 6.7 to 61.6%. Nevertheless, ED is considered a rare cause of male infertility, accounting for about 0.4–5% of all causes of male infertility. ED remains a poorly treated condition globally and current therapies, like oral medication, offer only temporary symptomatic relief and do not influence disease progression—patients are potentially on lifelong treatment, with ED worsening over time. In contrast, regenerative medicine may potentially reverse or halt the progression of ED processes. In this article, we review the evidence for intracavernosal injections of platelet-rich plasma (PRP) in the treatment of ED.

Abstract
INTRODUCTION Intracavernosal injections of platelet-rich plasma (PRP) or P-shot® are increasingly proposed as a curative treatment for organic sexual dysfunction despite the lack of evidence of effectiveness. OBJECTIVES We conducted a pilot study to evaluate the safety and efficacy of intracavernous PRP injections in patients with vascular erectile dysfunction (ED). METHODS Three intracavernosal injections of PRP were performed 15days apart in 15 patients with vascular ED unresponsive to medical treatment with 5-phosphodiesterase inhibitors and/or prostaglandin E instillations or injections. Questionnaires assessing erectile function (IIEF-EF, EHS, SEP, Sexual discomfort score) were completed prior to treatment and 1, 3 and 6 months after the last injection. RESULTS No side effects were noted during the study period. The IIEF-EF score was significantly improved after treatment (P<0.001) with a gain of 5 points at 1month, 4 points at 3months and 3 points at 6months (respectively P=0.001, P=0.003 and P=0.022). The other questionnaires did not change significantly. In total, 20% of patients considered that the erection lasted long enough to have a sexual intercourse (SEP score) before P-shot® versus 26.7% after the treatment (P=1). CONCLUSION This study suggests that the effect of P-Shot® remains moderate in cases of ED with vascular origin. Larger clinical studies are needed to determine the real effectiveness of this therapeutic strategy. LEVEL OF PROOF 2.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by bladder pain accompanied by irritative urinary symptoms, and typical cystoscopic and histological features. In this pilot study, we assessed the impact of lesion-targeted bladder injection therapy using a biocellular regenerative medicine on patients with refractory IC/BPS. The medicine, which was an autologous emulsified fat (Nanofat) and platelet-rich plasma (PRP) combination, was prepared intraoperatively. Six patients (aged 40-54 years), who completed a standard protocol of four consecutive treatments at 3-month intervals, were followed up at 6 months postoperatively. All patients (100%) reported marked (+3; +3 ~ -3) improvement of their overall bladder conditions. Mean bladder pain (from 8.2 to 1.7; range: 0 ~ 10), IC-related symptoms (from 18.5 to 5.7; range: 0 ~ 20), and bother (from 14.8 to 3.8; range: 0 ~ 16) improved significantly (p < 0.01). The normalization of bladder mucosal morphology with treatments was remarkable under cystoscopic examination, and no significant adverse events were found. The cultured mesenchymal stem cells from Nanofat samples of the six patients were verified in vitro. Our preliminary results suggest novel intravesical therapy with autologous Nanofat plus PRP grafting is safe and effective for refractory IC/BPS. Surgical efficacy might be attributed to an in vivo tissue engineering process.

Abstract
About 35% of patients affected by erectile dysfunction (ED) do not respond to oral phosphodiesterase-5 inhibitors (PDE5i) and more severe vasculogenic refractory ED affects diabetic patients. Innovative approaches, such as regenerative therapies, including stem cell therapy (SCT) and platelet-rich plasma (PRP), are currently under investigation. Recent data point out that the regenerative capacity of stem cells is strongly influenced by local immune responses, with macrophages playing a pivotal role in the injury response and as a coordinator of tissue regeneration, suggesting that control of the immune response could be an appealing approach in regenerative medicine. A new generation of autologous cell therapy based on immune cells instead of stem cells, which could change regenerative medicine for good, is discussed. Increasing safety and efficacy data are coming from clinical trials using peripheral blood mononuclear cells to treat no-option critical limb ischemia and diabetic foot. In this review, ongoing phase 1/phase 2 stem cell clinical trials are discussed. In addition, we examine the mechanism of action and rationale, as well as propose a new generation of regenerative therapies, evolving from typical stem cell or growth factor to immune cell-based medicine, based on autologous peripheral blood mononuclear cells (PBMNC) concentrates for the treatment of ED.

Abstract
INTRODUCTION Erectile Dysfunction (ED) and Peyronie's Disease (PD) are debilitating medical conditions affecting patients' quality of life (QoL). Platelet-rich plasma (PRP) injections are one of the various emerging approaches proposed to treat these medical conditions. AIM To describe the evidence of the potential role of PRP injections in ED and PD. METHODS The authors conducted a systematic review according to the PRISMA statement using the following databases in November 2019: The National Library of Medicine (PubMed), Ovid Medline, Cochrane, Scopus, Embase, and Embase classic. The search was performed using keywords drawn from studies on the use of PRP in ED and PD in clinical and preclinical studies. RESULTS Eighteen articles met the inclusion criteria for review, including 12 studies on the use of PRP in humans and 6 on the use of PRP in rats. Ten studies reported on the efficacy of PRP in ED exclusively, 7 in PD exclusively and one in both conditions. In humans, 6 and 3 studies showed promising results in PD and ED, respectively. No major complications were noted. Unwanted minor side effects were noted by studies reporting on PD, including mild penile bruising, ecchymosis, hematomas as well as transient hypotension noted in 2 out of 90 patients. CONCLUSION PRP injections for the treatment of ED may be promising, but no recommendation can be made because of scarce evidence. Safety and effectiveness of this therapy in the treatment of ED and PD require further preclinical and clinical studies with standardized protocols to gain an adequate insight into its potential implications. Patients should be offered to be part of such trials to better understand PRP potential.

Abstract
This study aimed to evaluate the effectiveness of ICI of platelet-rich plasma (PRP) in addition to daily oral tadalafil intake in diabetic erectile dysfunction (ED) patients non-responding to PDE5 inhibitors. Overall, 48 patients complaining of ED non-responding to on-demand PDE5 inhibitors were allocated into 2 equal groups, diabetics and non-diabetics that were given a daily dose of 5 mg tadalafil plus vardenafil 20 mg on demand during the study besides being subjected to 3 doses of ICI of PRP, 4 weeks apart. Responses to on-demand PDE5 inhibitors, International index of erectile function-5 (IIEF-5) score, erection hardness scores (EHS) and pharmaco-dynamic duplex studies were assessed. After PRP injections, 33% and 50% of cases were satisfied with on-demand PDE5 inhibitors, respectively, whereas 41% and 66% of them showed improved EHS response. Compared with baseline scores, the mean IIEF-5 scores were significantly improved after PRP therapy in the diabetic ED group (12.1 vs. 8.04, p = 0.003) as well as in the non-diabetic ED group (14.8 vs. 10.2, p = 0.001) linked to pharmaco-penile duplex readings. Both good and fair diabetic control exhibited significant responses to ICI therapy of PRP compared with bad controlled cases. The significant improvement included; the IIEF-5 score increase (86.7%, 126% vs. 16.1%), improved EHS as well as penile duplex readings. Baseline HbA1C demonstrated a significant negative correlation with IIEF-5 score before (p = 0.019) and after PRP therapy (p = 0.002) respectively. It could be concluded that ICI of PRP could be an effective therapy for treating ED patients non-responding to on-demand oral PDE5 treatment.

Abstract
Penile concerns include erectile dysfunction (ED) and Peyronie disease (PD). Restorative therapies including Stem Cell Therapy (SCT) and Platelet Rich Plasma (PRP) injections are proposed to treat these concerns. SCT encompasses the harvesting and injection of mesenchymal stem cells or stromal vascular fractions from various tissue sources. PRP is derived autologously from a patient's plasma and is then injected into the penile tissue. These therapies repair damaged penile tissue and promote both new cellular and vascular growth, as demonstrated in basic science studies. Human trials on SCT and PRP for both ED and PD and have yielded promising results with few side effects. While encouraging, small cohort size and lack of blinding or placebo control limit these studies' external validity. Recently, the first double-blinded randomized controlled trial on PRP for ED was published, providing significant evidence of efficacy. With the rapid commercial availability of SCT and PRP for ED and PD, it is imperative to perform more randomized and placebo-controlled trials with standardized procedures and preparations to evaluate efficacy and safety. This narrative review will summarize the available literature on these penile restorative therapies to date.

Abstract
OBJECTIVES The aim of the study was to evaluate the efficacy and safety of platelet-rich plasma (PRP) for the treatment of stress urinary incontinence (SUI). METHODS This was a prospective observational pilot study conducted in a tertiary referral unit, enrolling women with SUI booked for SUI surgery. A total of 20 consecutive women met the inclusion criteria and attended all follow-ups. All participants underwent 2 PRP injections into the lower one third of the anterior vaginal wall at 4- to 6-week intervals. At baseline, they underwent urodynamic studies, a 1-hour pad test, and completed the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms and King's Health Questionnaire. At follow-up visits (1, 3, and 6 months), patients underwent the 1-hour pad test and completed the King's Health Questionnaire, International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms, and Patient Global Impression Scale of Improvement. Primary outcome was to evaluate posttreatment SUI. Secondary outcomes included assessment of patient-reported questionnaires, assessment of urine loss (1-hour pad test), and the level of discomfort during injections (visual analog scale score). Statistical analysis was performed before PRP and 1, 3, and 6 months after the last treatment. RESULTS A significant improvement in SUI symptoms was observed 3 months after treatment with a further improvement at 6 months. A mean reduction of 50.2% in urine loss was observed in the 1-hour pad test. At the 6-month follow-up, 80.0% of women reported to be at least improved. No adverse effects were observed. CONCLUSIONS Platelet-rich plasma injections were both effective and safe at least in the short term and could be offered as an alternative outpatient procedure for the treatment of SUI. However, these encouraging findings warrant further investigation with randomized controlled trials.

Abstract
Erectile dysfunction affects an increasing number of men. The mainstays of management include oral medications, local erectogenic agents, and surgical placement of prosthetic devices. Newer technologies such as stem cell and gene therapy have been investigated as a means to restore spontaneous erectile capacity. Mesenchymal stem cells are thought to produce a local immunomodulatory and pro-repair milieu at the area of injury or needed repair. Gene therapy involves targeting the erectogenic pathway to augment factors involved in producing a natural erection. Such therapies are considered experimental and should be used in the setting of a clinical trial with appropriate oversight.

[PMID: 34434257 PMCID: PMC8381411 DOI: 10.1177/17562872211026421] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Accepted: 06/01/2021] [Indexed: 01/17/2023] Open
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.

[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
Erectile Dysfunction (ED) is defined as the inability to achieve and maintain an erection sufficient for sexual intercourse. Available treatments for ED provide only symptomatic relief, which is for the most part temporary. Regenerative therapies such as Low Intensity Shockwave, Platelet-Rich Plasma, and Stem Cell therapy can potentially provide a "cure" for ED by reversing the underlying pathology of ED rather than just treating the symptoms. Low Intensity Shockwave therapy is the most evidence based at this point and is thought to act by improving penile blood flow, repairing previous nerve damage, and activating stem cells. Stem Cell therapy takes advantage of the self-replicative potential of stem cells to create new corporal tissue, but also to recruit host cells and angiogenic factors to stimulate endogenous repair. Platelet-Rich Plasma therapy uses concentrated growth factors that already exist within the bloodstream to repair damaged nerves and increase penile blood flow. The use of combination restorative therapy may provide an additive or synergistic benefit greater than any one therapy alone because of its overlapping mechanisms of action on the penis but is a topic that remains to be studied.

Abstract
Erectile dysfunction (ED) is a common condition with a significant impact on the quality of life. Regenerative medicine maladies are intended to repair or replace damaged tissues and organs through different therapeutic mechanisms. Our aim was to study the effect of intra-corporeal injection (ICI) of platelet-rich plasma (PRP) in ED patients. Thirty-four patients' erectile function was evaluated by filling up an abridged form of the international index of erectile function (IIEF-5) before and after PRP therapy. ICI of PRP was done once per week for 2 months. All patients were prescribed PDE5Is for one month after PRP therapy. Penile haemodynamics was assessed using 20 µg of PGE1 before and 3 months after initiating PRP therapy. Interestingly, our study had shown that there was a statistically significant difference in the IIEF-5 score after ICI of PRP (-5.5, ±5.2, p=<0.001). Furthermore, in multiple logistic regression model for PRP responsiveness, smoking and IIEF score before PRP were the only significant independent variables (p = .040, p = .023 respectively). PRP injection for ED patients may be a promising modality as well as baseline IIEF-5, and smoking status can be used as predictors for a satisfactory response to PRP in such patients.

Restorative Therapies for Erectile Dysfunction: Position Statement From the Sexual Medicine Society of North America (SMSNA). Sex Med 2021; 9:100343. [PMID: 34000480 PMCID: PMC8240368 DOI: 10.1016/j.esxm.2021.100343] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 02/22/2021] [Accepted: 02/23/2021] [Indexed: 02/07/2023] Open
Abstract
INTRODUCTION Current non-invasive treatments for erectile dysfunction (ED) include oral medications, intracavernosal injections, and vacuum-assisted devices. Though these therapies work well for many, a subset of patients have contraindications or are unsatisfied with these options. Restorative therapies for ED are a new frontier of treatments focused on regenerating diseased tissue and providing a potential "cure" for ED. AIM The aim of this position statement is to examine existing clinical trial data for restorative therapies and identify elements that require further research before widespread adoption. METHODS A literature review was performed to identify all clinical trials performed with regenerative therapy for ED. This includes treatments such as stem cell therapy (SCT), platelet rich plasma (PRP), and restorative related technologies like low-intensity shockwave therapy (LiSWT). MAIN OUTCOME MEASURES Most clinical trials in restorative therapies were assessed for safety, feasibility, or efficacy. This included recording adverse events, changes in sexual function and erectile function questionnaires, and diagnostics measures. RESULTS To date there is an absence of robust clinical data supporting the efficacy of restorative therapies regarding ED, though technologies such as LiSWT have established relative safety. CONCLUSIONS Restorative therapies are a promising technology that represents a new frontier of treatment geared towards reversing disease pathology rather than just treating symptoms. However, current published clinical studies are limited. Future work needs to be adequately powered, multi-center, randomized, sham/placebo-controlled trials in well-characterized patient populations to ensure safety and demonstrate efficacy. Until these studies are done, restorative therapies should be reserved for clinical trials and not offered in routine clinical practice. Liu JL, Chu KY, Gabrielson AT, et al.

Abstract
INTRODUCTION Peyronie's disease is a common cause for consultation in urology. Many controversies surround its treatment. No French Guidelines have been published so far. The Committee of Andrology and Sexual Medicine of the French Association of Urology therefore offers a series of evidence-based recommendations. MATERIALS AND METHODS These recommendations are made according to the ADAPTE method, based on European (EAU, ESSM), American (AUA, ISSM) and Canadian (CAU) recommendations, integrating French specificities due to the availability of treatments, and an update of the recent bibliography. RESULTS The assessment of the disease is clinical. Patients with functional impairment or significant psychological repercussions may be offered treatment. The benefits and drawbacks of each treatment should be explained to the patient. Regarding non-surgical treatments, no available treatment has market authorization in France. Vitamin E is not recommended. Analgesic (oral or low-intensity shock waves) or proerectile treatments may be offered as needed, as well as traction therapy. Due to the unavailability of collagenase injections, verapamil injections may be offered. Surgical treatments are to be considered in the stabilized phase of the disease, and consist of performing a plication, an incision-graft or the placement of a penile implant according to the patient's wishes, the curvature and the penis size, as well as erectile function. Combination treatments can be offered. CONCLUSION The management of Peyronie's disease is complex, and the levels of evidence for treatments are generally low. The success of treatment will depend on the quality of the initial assessment, the patient's information and understanding of the expected effects, and the practitioner's experience.

Abstract
Background: The regenerative efficacy of platelet-derived products has been recently investigated in the treatment of pelvic floor disorders (PFDs). We aimed to synthesize the current evidence of platelet-rich plasma (PRP) products used in urogynaecological disorders including vaginal atrophy, pelvic organ prolapse (POP), urinary incontinence, vaginal fistulas and vaginal mesh exposure. Methods: A meticulous search of the currently available literature on the use of PRP for the management of PFDs was performed using 3 electronic databases. Results: PRP could be a feasible alternative modality for the management of vaginal atrophy with favourable outcomes in vaginal atrophy parameters and patients' satisfaction, especially when hormone therapy is contraindicated. In patients with POP, an increase in collagen concentration after PRP application was observed while the use of PRP resulted in improvement of stress urinary incontinence symptoms. A considerable proportion of vesicovaginal fistulas were treated after application of PRP-based injections. Conclusions: There is only limited evidence of the use of PRP for PFDs. Platelet-rich plasma appears to be a promising, easy to apply, cost-effective and feasible alternative therapeutic modality for the management of various urogynaecological disorders. Future randomized trials are needed to confirm the efficacy of PRP in the treatment of urogynaecological disorders.

Abstract
BACKGROUND Animal studies postulate that platelet-rich plasma (PRP) injections improve key elements of the pathophysiologic mechanisms leading to erectile dysfunction (ED). AIM To conduct the first double-blind, randomized, placebo-controlled trial assessing the efficacy and safety of PRP injections in patients with mild and moderate ED. METHODS Sixty sexually active patients with mild and moderate ED were randomly assigned to two sessions, with a one-month difference, of 10 mL PRP (n = 30) or placebo (n = 30) intracavernosal injections. An FDA-approved separation system was used. Patients were evaluated at 1, 3 and 6 months after completion of the treatment protocol. A per-protocol analysis was applied. All participants withheld any ED treatment during the trial. OUTCOMES The achievement of minimal clinically important difference (MCID) in the International Index of Erectile Function - Erectile Domain (IIEF-EF) from baseline to 6 months after final treatment. Erectile function at all time points, as well as safety of PRP injections, were also evaluated. RESULTS At 6 months, a MCID was achieved by 20/29 (69%) patients in the PRP group compared to 7/26 (27%) in the placebo group. The risk difference between the two groups was 42% (95%CI: 18-66), P < 0.001 and the baseline-adjusted mean between-group-difference in the IIEF-EF score was 3.9 points (95%CI: 1.8-5.9). Similarly, a statistically significant difference of both the number of participants attaining a MCID and the IIEF-EF score was also observed at the 1- and 3-month evaluation between the two groups. Accordingly, patients receiving PRP were more satisfied with the treatment. No adverse events were observed during the study period. CLINICAL IMPLICATIONS Intracavernosal PRP injection therapy used as outlined in this trial appears to be a safe and effective short-term treatment for the management of mild to moderate ED. STRENGTHS & LIMITATIONS We conducted the first clinical trial exploring the role of PRP in the management of ED. Conversely, our findings lack external validity due to single-center design. Furthermore, our results cannot be extrapolated to other PRP separation systems. CONCLUSIONS PRP intracavernosal injections may be a promising addition to the urologist's armamentarium for the management of ED. Still, further high-quality studies are warranted to corroborate our findings. Evangelos P, Mykoniatis I, Pyrgidis N, et al.

Abstract
Erectile dysfunction (ED) has been defined as the inability to attain or maintain penile erection sufficient for successful sexual intercourse. ED carries a notable influence on life quality, with significant implications for family and social relationships. Because atherosclerosis of penile arteries represents one of the most frequent ED causes, patients presenting with it should always be investigated for potential coexistent coronary or peripheral disease. Up to 75% of ED patients have a stenosis of the iliac-pudendal-penile arteries, supplying the male genital organ’s perfusion. Recently, pathophysiology and molecular basis of male erection have been elucidated, giving the ground to pharmacological and mechanical revascularization treatment of this condition. This review will focus on the normal anatomy and physiology of erection, the pathophysiology of ED, the relation between ED and cardiovascular diseases, and, lastly, on the molecular basis of erectile dysfunction.

Abstract
Introduction Platelet-rich plasma (PRP) is useful in the treatment of different conditions and diseases as it contains concentrated levels of many growth factors. Aim The aim of this study was to investigate the effectiveness of autologous PRP application in the treatment of erectile dysfunction (ED) in patients with metabolic syndrome. Methods In this prospective study conducted in June 2019, 31 patients with ED were included. The International Index of Erectile Function–Erectile Function domain (IIEF-EF) questionnaires were used to evaluate erectile function (EF). After administering the intracavernous autologous PRP 3 times with an interval of 15 days, IIEF-EFs were evaluated 1, 3, and 6 months later. Main Outcome Measure IIEF in the 1st, 3rd, and 6th months and adverse events. Results While the mean IIEF-EF was 18 before the application, the mean IIEF-EF was 20 in the first, third, and sixth months after the procedure (P < .001). However, even though IIEF-EF values increased numerically, median value remained within the mild-moderate classification (scores between 17 and 21). Postprocedure sexual satisfaction scores were significantly higher than preprocedure values (8 vs 6, respectively; P = .002). In the first follow-up of a patient after the 3rd injection, a 4-mm diameter fibrotic plaque was observed on the ventral side in the middle of the penis shaft. Conclusion In conclusion, our findings suggest that larger studies as well as placebo-controlled studies are needed to add PRP to the treatment protocol in ED. T Taş,Çakıroğlu, E Arda, et al.

[PMID: 33452330 PMCID: PMC7810841 DOI: 10.1038/s41598-020-80598-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2020] [Accepted: 12/22/2020] [Indexed: 11/08/2022] Open
Abstract
The study aims to evaluate the effectiveness of local injection of autologous platelet rich plasma (A-PRP) as a treatment for women suffering from stress urinary incontinence (SUI). In a prospective intervention study, twenty consecutive women suffering from SUI were treated with A-PRP injection at anterior vaginal wall where mid-urethra locates. Self-reported questionnaires were used to measure pre-treatment, 1 month and 6 months post-treatment symptom severity. Secondary outcomes of sexual function and treatment effect sorted by age were analyzed with valid statistical methods. A-PRP is effective in relieving SUI symptoms at both 1 month and 6 months post-treatment without significant adverse reactions reported. It seems to have a trend that treatment success rate with cured and improved symptoms was slightly higher in the younger group, although it did not reach statistical significance (P = 0.07). No significant changes in sexual function before and after the treatment were reported by the patients. This pilot study is the first to report A-PRP treatment effect for SUI in women. The result suggested that A-PRP is a considerable treatment option for mild to moderate SUI cases. It also opens up further research opportunities for A-PRP’s clinical applications.

Abstract
PURPOSE OF REVIEW To highlight and review encouraging preliminary studies behind several alternative products and interventions for erectile dysfunction (ED). RECENT FINDINGS Alternative treatments for ED are becoming more prevalent with increased consumer interest. "Natural" products are sold online, and numerous clinics offer various off-label and investigational interventions. These alternative treatments have demonstrated varying degrees of efficacy in randomized trials and meta-analyses, but none of these interventions has robust enough evidence to be considered first-line therapy. These treatments may find a role in combination with guideline treatments or may be used in novel penile rehabilitation research protocols. With growing interest in alternative treatment for men's health, an awareness of the literature is imperative for patient counsel. Alternative treatments, like L-arginine, have a growing body of evidence for efficacy in combination with PDE5i, and low-intensity shock wave therapy and stem cell therapy continue to demonstrate encouraging outcomes in ED trials.

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.

Abstract
INTRODUCTION Platelet-rich plasma (PRP) is an increasingly used unconventional treatment option for erectile dysfunction (ED). The validity of PRP as a potential treatment for ED has been proposed in limited human trials. Furthermore, the costs associated with PRP for ED treatment are not readily promoted to patients. The goal of this review was to determine the efficacy and costs of PRP based on currently available literature and Canadian data. METHODS A comprehensive literature review of available PRP studies and current published data pertaining to cost, availability, and provider clinics globally was conducted using the PubMed database. Physicians offering genital PRP in Canada were identified using internet searches and PRP provider directories. Physician qualifications, clinic locations, and cost information were obtained from provider websites and telephone calls to identified clinics. RESULTS Availability of PRP injections offered for treating ED is increasing globally. There are currently no peer-reviewed publications to substantiate anecdotal evidence pertaining to the efficacy of PRP as a viable treatment option for ED patients. Our results indicate 19 providers for PRP injections in Canada, costing on average $1777 CAD per injection. No providers were affiliated with academic institutions and providers varied in their area of clinical speciality and training. CONCLUSIONS To our knowledge, there is currently no research underway investigating the clinical efficacy of PRP for ED treatment despite its broad availability and significant cost. Patients should be informed of the lack of substantiated efficacy and safety data, as the reliability of PRP treatments requires further evaluation.

Abstract
INTRODUCTION Efforts to understand and unlock the body's potential for regeneration have increased dramatically in recent years. So-called "biohacking" hopes to improve functionality and reverse disease processes. OBJECTIVES This review will seek to summarize the available data for the use of platelet-rich plasma, cellular therapies, and other novel therapeutics within sexual medicine. METHODS The PubMed database search was performed using the keywords "Stem cell therapy in Erectile dysfunction (ED)", "Gene therapy in ED", "Novel therapeutics for ED", and "Biohacking". Popular news articles for regulation of stem cell therapy were reviewed. RESULTS Research efforts have managed to produce an array of novel therapeutics, including stem cell therapy and platelet-rich plasma. Although the use of these items has been largely focused within specialties other than urology, applications involving sexual medicine have been documented and appear to be increasing. CONCLUSION Despite evidence of these technologies being adopted within clinical practices as revenue-generators, quality data to support efficacy are quite limited.
