Peyronie's disease (PD) has detrimental effects on the quality of life, mental health, sexual functioning and several other aspects that increase the risk of relationship problems. However, no study to date has assessed the risk of relationship separation in med with PD. Herein, we utilized data from Swedish national registers to examine the risk of relationship separation in men with PD. We conducted a matched cohort study on men born 1933–1992, followed from 1997 to 2013. PD was defined as a physician-assigned diagnosis according to the International Classification of Diseases, Tenth version. Each man with PD (n = 8020) was matched with 10 comparison men. We defined relationship separation as (1) ever separated, and (2) separation rate. We used log-linear regression to estimate the risk ratio, and rate ratio of relationship separation. We adjusted for matching variables (birth year and country of birth), and an indicator of each follow-up year. We found that men with PD had a 13% increased risk of relationship separation (risk ratio 1.13, 95% confidence interval [CI] 1.08–1.17). The rate of relationship separation events, measured on a yearly basis, was increased by 18% (rate ratio 1.18, CI 1.12–1.24), and remained similar when adjusting for follow-up year and socio-economic status.

The article discusses a technique called "V-I penoscrotal reconfiguration" for the surgical treatment of congenital webbed penis (CWP). The authors propose using scrotal skin for penile shaft reconstruction due to its similar color, thickness, pliability, elasticity, and consistency. However, they caution that the creation of linear scars from this technique can lead to complications such as hypertrophic scars, unsuitable penile curvature, and pain. They suggest further studies with longer follow-ups to assess the risk of complications in younger patients. The authors also mention the use of transposition local flaps harvested from the scrotum as an alternative technique to avoid complications. [Extracted from the article]

Objective: Predisposing factors of Peyronie’s disease remain controversial. We know that obesity has extremely negative effects on erectile tissue. Therefore, in our study, we aimed to examine the relationship between Peyronie’s disease and the body shape index (ABSI), which is a new parameter for the evaluation of visceral adiposity. Materials and Methods: In this study, 55 healthy volunteers (group-1) and 50 Peyronie’s disease patients (group-2). Age, comorbidities, waist circumference (WC), height, body mass index (BMI), testosterone, fasting glucose, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, International Index of Erectile Function (IIEF), and ABSI scores of all patients were analyzed. In addition, plaque sizes, duration of symptoms, and curvature degrees of patients in group 2 were calculated. Results: The mean ages of group 1 and group 2 were 57.02±8.34 years and 56.02±10.65 years, respectively (p>0.05). Fasting glucose, WC, BMI, and ABSI values were significantly higher in group 2 (p=0.031, p<0.001, p=0.026 and p<0.001). LDL and HDLvalues were similar between both groups (p>0.05). The IIEF score was observed to be lower in group 2 (p<0.001). In terms of ABSI values, the discrimination power of Peyronie’s disease was strong. The cut-off value for the ABSI score was 0.08. For this cut-off point, classification success was determined as 88.0% sensitivity and 80.0% selectivity. Conclusion: ABSI can be a reliable independent risk factor for Peyronie’s disease and a predictor of visceral adiposity. [ABSTRACT FROM AUTHOR]

Background: Peyronie's disease (PD) is a connective tissue disorder that affects the penis and is characterized by abnormal collagen structure in the penile tunica albuginea, resulting in plaque formation and penile deformity. PD's overall prevalence is estimated at 3.2% to 8.9%, with rates as high as 20.3% among men with type 2 diabetes mellitus (DM). However, the characteristics of DM associated with PD complications remain unclear. Aim: To explore clinical associations between DM characteristics and PD complications. Methods: We conducted a retrospective analysis of patients with DM and PD who presented at our institution between 2007 and 2022. We examined patients' clinical histories, DM- and PD-related clinical parameters, and complications. Penile deformities were assessed through physical examination, photographs, and penile Doppler ultrasound. Patients were categorized into subgroups based on age of DM onset: early (<45 years), average (45-65 years), and late (>65 years). Outcomes: Outcomes included effects of DM characteristics on PD development, progression, and severity. Results: In total, 197 patients were included in the evaluation. Early-onset diabetes and elevated hemoglobin A1c (HbA1c) levels exhibited significant correlations with the early development of PD (ρ = 0.66, P < .001, and ρ = –0.24, P < .001, respectively). Furthermore, having DM at an early age was associated with the occurrence of penile plaque (ρ = –0.18, P = .03), and there were no significant differences in plaque dimensions (ρ = –0.29, P = .053). A rise in HbA1c levels after the initial PD diagnosis displayed positive correlations with the formation of penile plaque (ρ = 0.22, P < .006). Clinical Implications: These findings emphasize the need for comprehensive assessments and personalized treatment strategies for individuals with DM and PD. Enhanced management approaches can improve outcomes for those facing both challenges. Strengths and Limitations: Limitations include the single-site retrospective design with potential selection bias, inaccuracies in medical record data, and challenges in controlling confounding variables. Conclusions: This study highlights that early-onset diabetes and poor diabetes control, as indicated by a subsequent rise in HbA1c levels following PD diagnosis, are significantly correlated with the onset and severity of PD. Revealing the mechanisms behind these findings will help us develop better management strategies for individuals with DM and PD. [ABSTRACT FROM AUTHOR]

Context Objective Evidence acquisition Evidence synthesis Conclusions Patient summary Data supporting successful and satisfactory penile prosthesis (PP) implantation outcomes are mainly based on subjective, rather than objective, analysis.To systematically review and objectively analyze, all available data related to patient and partner PP satisfaction.An extensive search was performed, including the following key‐words: (“penile prosthesis” and “satisfaction”). The search, which accrued data from January 1, 1969, up to July 31, 2023, was restricted to English‐language articles including human participants.Out of 663 retrieved articles, 83 were considered including, 12,132 subjects with a mean age and mean follow‐up of 58.6 [range 20; 77.1] years and 47.6 [range 6; 374] months, respectively. Overall, a high patient satisfaction rate was observed 83[80; 86]%. The satisfaction rate increased in subjects with three‐piece PP and in those with a higher rate of cardiovascular or neurological diseases and was independent of the patient's age. Partner's satisfaction rate was lower when compared to that observed in men and it increased according to the use of inflatable devices and the presence of patient Peyronie's disease. The long‐term complication rate was limited ranging from 3% for erosion to 4.6% when mechanical failure was considered.Patient and partner satisfaction is excellent and increases with time. The number of complications is limited and is strongly associated with the presence of diabetes mellitus.We found a high couple satisfaction score that was higher when reported by males compared to females. Patient satisfaction increased with time, and it was independent of age. [ABSTRACT FROM AUTHOR]

Background: Peyronie's disease (PD) is a localized fibrosis of tunica albuginea, which causes the anatomical and functional changes to the penis. Corporoplasty with grafting is indicated in severe (>60°) and complex curvature. Buccal mucosa is the most favored autologous graft material nowadays. The ventrolateral aspect of lingual mucosa has similar histological features to the rest of the oral cavity. Methods: This study aimed to test the efficacy, safety, durability, and reproducibility of corporoplasty with lingual mucosal graft (LMG) in the surgical treatment of PD in terms of surgical outcome, sexual function, and donor site complications. This prospective study included 19 patients of PD with severe and complex curvature, who underwent corporoplasty with LMG. Surgical and functional outcomes were assessed at follow-up planned at 2 weeks, 3 months, 6 months, 1 year, and 2 years. Results: The mean operative time was 126.31 ± 21.45 min. Additional Nesbit's plication to correct the residual deformity was required in 26% (5 / 19) of patients. Straightening of the penis (curvature <10°) was achieved in 89% (17 / 19) of patients. Increase in the penile length (>1 cm) postoperatively was achieved in 63% (12 / 19) of patients and a shortening of penis occurred in 5% (1 / 19) of patients. Newer onset erectile dysfunction developed in 11% (2 / 19) of patients, and patient and partner satisfaction rates were 89% (17 / 19) and 84% (16 / 19), respectively, in a mean follow-up of 20.66 ± 5.37 months. Donor site complications were minimal and no patient had any salivary changes or speech disturbances. Conclusion: LMG provided excellent short-term results in terms of deformity correction, improved sexual function, and minimal donor site morbidity. The method is simple and reproducible, and multicenter studies with larger number of cases with longer follow-up are required to confirm these favorable results. [ABSTRACT FROM AUTHOR]

Background Objective Material/methods Results Discussion Conclusion Peyronie's disease is characterized by the formation of fibrotic plaques in the penile tunica albuginea. Effective treatments are limited, warranting the investigation of new promising therapies, such as the application of microRNAs that regulate fibrosis‐related genes.We aimed to investigate the therapeutic potential of mimicking microRNA‐29b in a fibrin‐induced rat model of Peyronie's disease.The study was designed in two phases. To establish an optimal Peyronie's disease model, rats received either human fibrin and thrombin or saline solutions into the tunica albuginea on days 0 and 5. The animal model validation was done through expression and histopathological analyses, the latest by an experienced uropathologist. After validation, we performed microRNA‐29b treatment on days 14, 21, and 28 of the study. This phase had control (normal saline) and scramble (microRNA scramble) groups. The mid‐penile shaft was removed on day 30 for histological examination and molecular analyses in both study stages.The control group displayed typical tunica albuginea histologic architecture in the animal model validation. In Peyronie's disease group, the Hematoxylin and eosin and Masson Trichrome staining methods demonstrated an interstitial inflammatory process with concomitant dense fibrotic plaques as well as disarrangement of collagen fibers. Additionally, we found out that reduced microRNA‐29b (p = 0.05) was associated with significantly increased COL1A1 and transforming growth factor β1 genes and proteins (p > 0.05) in the Peyronie's disease group. After treatment with mimic microRNA‐29b stimulation, the Hematoxylin & eosin and Masson Trichrome staining revealed a discrete and less dense fibrotic plaque. This result was associated with significantly decreasing expression of COL1A1, COL3A1, and transforming growth factor β1 genes and proteins (p < 0.05).The fibrin‐induced animal model showed significant histopathological and molecular changes compared to the Control group, suggesting that our model was appropriate. Previous findings have shown that increased expression of microRNA‐29b was associated with decreased pathological fibrosis. In the present study, treatment with microRNA‐29b decreased the gene and protein expression of collagens and transforming growth factor β1. This study reveals the therapeutic potential for Peyronie's disease involving molecular targets.MicroRNA‐29b application on the rat's tunica albuginea attenuated fibrosis, arising as a novel potential strategy for Peyronie's disease management.

Background: This study compared the differences of microvesicles (MVs) and microvesicles-delivering Smad7 (Smad7-MVs) on macrophage M1 polarization and fibroblast differentiation in a model of Peyronie's disease (PD). Methods: Overexpression of Smad7 in rat BMSCs was obtained by pCMV5-Smad7 transfection. MVs were collected from rat BMSCs using ultracentrifugation. In cells, 100 µg/mL of MVs or Smad7-MVs were used to treat the 100 ng/mL of lipopolysaccharide (LPS)-induced RAW264.7 cells or 10 ng/mL of recombinant transforming growth factor-β1 (TGF-β1)-induced fibroblasts. The pro-inflammatory cytokines and markers of M1 macrophages were measured in RAW264.7 cells, and the migration and markers of fibroblast differentiation were measured in fibroblasts. In rats, 50 µg of MVs or Smad7-MVs were used to treat the TGF-β1-induced animals. The pathology of tunica albuginea (TA), the markers of M1 macrophages and fibroblast differentiation in the TA were measured. Results: The MVs or Smad7-MVs treatment suppressed the LPS-induced macrophage M1 polarization and TGF-β1-induced fibroblast differentiation. Moreover, the Smad7-MVs treatment decreased the fibroblast differentiation compared with the MVs treatment. In the TGF-β1-induced TA of rats, MVs or Smad7-MVs treatment ameliorated the TA fibrosis by suppressing the macrophage M1 polarization and fibroblast differentiation. There was no significance on the M1-polarized macrophages between the MVs treatment and the Smad7-MVs treatment. Meanwhile, the Smad7-MVs treatment had an edge in terms of suppressing the fibroblast differentiation in the TGF-β1-induced PD model compared with the MVs treatment. Conclusions: This study demonstrated that Smad7-MVs treatment had advantages over MVs treatment in suppressing of fibroblast differentiation in a model of PD. [ABSTRACT FROM AUTHOR]

Peyronie's disease (PD) affects the penile albuginea, resulting in penile deformity, pain, erectile dysfunction (ED), and an anxious–depressive state. PD diagnosis involves a thorough medical history, penile palpation, documentation of the penile deformation, a dynamic penile echo color Doppler ultrasound (PCDU), and the completion of questionnaires for the evaluation of pain, ED, and psychometric tests. The aim of this study was to evaluate the symptoms of PD and their prevalence in PD patients in the active phase who had access to our andrology clinic. Inclusion criteria: availability of data on patients diagnosed with PD, including detailed medical history, blood tests, penile palpation, photographic documentation of penile deformity, and penile PCDU. Exclusion criteria: PD patients in the stable phase or those without the specified tests and data mentioned above. Our study found a higher prevalence of PD in younger patients (24.2%), a higher coexistence of PD with chronic prostatitis (35.6%), a higher percentage of cases of association between penile deformity and penile curvature (84.4%), a higher prevalence of "significant anxiety" (88.4%), a higher presence of plaque calcification (35.6%), and the detection of a longer duration of the first phase of PD (>18 months). The most frequently observed type of penile curvature was dorsal, followed by left lateral, right lateral, and, less commonly, ventral. We observed a significant statistical correlation between patient age and IIEF score, indicating that patients over the age of 40 years are at a higher risk of experiencing ED. We found a strong statistical relationship between VAS score and age. As age increases, the VAS score decreases, suggesting that younger patients reported more penile pain compared to those who were older than 40 years. Furthermore, we found that penile pain has a significant impact on the psychological state of PD patients. We also found that 38.8% of PD patients suffered from severe anxiety. In relation to this, psychotherapy should be integrated into PD treatment to improve the quality of life and treatment adherence. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Purpose: To review the literature on the topic, to suggest a common line of treatment applicable across a wide community of specialists, and to contribute in maintaining the high level of interest in this disease. Methods: A comprehensive and exhaustive review of the literature was performed, identifying hundreds of articles on the topic. Results: Peyronie's disease is a condition that has been recognized, studied, and treated for centuries; despite this, if one excludes surgery in cases in which the deformity is stable, no clear treatment (or line of treatment) is available for complete relief of signs and symptoms. Treatment options were divided into local, oral, and injection therapy, and a wide variety of drugs, remedies, and options were identified. Conclusions: Low-intensity extracorporeal shock wave therapy, vacuum therapy, penile traction therapy, phosphodiesterase type 5 inhibitors, hyaluronic acid, and collagenase of Clostridium histolyticum may be recommended only in specific contexts. Further studies on individual options or potential combinations are required. [ABSTRACT FROM AUTHOR]

Objective: To present the functional results obtained and the possible surgical difficulties after the surgical treatment of Dupuytren's disease (DD) recurrence in patients previously treated with Clostridium histolyticum (CCH) collagenase. Materials and methods: In this prospective study, 178 patients with DD were treated with CCH from 2011 to 2018; During long-term postoperative follow-up, 34 patients (19.1%) had recurrence of DD. In all patients injected in the IFP the disease recurred; In patients injected in the MCP, recurrence was highest in grade III and IV of the Tubiana classification, with involvement of the 5th finger and the two-finger Y-chord. Fourteen patients (7,8%) required surgery by partial selective fasciectomy due to recurrence of cord DD infiltration. The clinical and functional results of the patients, the difficulty of the surgical technique and the anatomopathological analysis of the infiltrated cords were evaluated in comparison with those of cords and patients who had had no previous CCH treatment. Results: In all patients, cord rupture was achieved after injection, reducing joint contracture. In 14 patients, we observed during the follow-up the existence of DD recurrence that required surgical treatment by selective partial fasciectomy. There were no major difficulties in surgery and good clinical and functional results at 6 months of follow-up. The anatomopathological study of the resected tissue did not present histological alterations with respect to the samples obtained from patients initially treated by selective partial fasciectomy. Conclusions: Selective fasciectomy after CCH injection does not lead to important operative difficulties, as long as the CCH injection is performed according to the recommendations. There were no histological changes in the tissue after CCH injection. Level of evidence: III. [ABSTRACT FROM AUTHOR]

Background: Little is known about patients' pre‐treatment expectations in Peyronie's disease (PD). Objective: To evaluate in detail patients' expectations of conservative therapy and surgery. Patients and methods: This multi‐center study prospectively enrolled 317 PD patients, who were scheduled to receive conservative therapy or surgery between 2019 and 2022 at the Department of Urology of the University Medical Center Hamburg‐Eppendorf, and the Center of Reproductive Medicine and Andrology, University Medical Center Muenster, both Germany. The primary end‐point was patients' pre‐treatment expectations of conservative therapy and surgery, measured with the Stanford Expectations of Treatment Scale (SETS). Secondary end‐points included patient‐reported psychological and physical symptoms, penile pain, symptom bother and erectile function, measured with the Peyronie's disease questionnaire (PDQ) and International Index of Erectile Function Erectile Function Domain (IIEF‐EF). Results: In total, 239 (75%) and 78 (25%) patients were scheduled for the conservative therapy and surgery, respectively. Patients undergoing surgery had higher positive and negative mean SETS expectations scores (14 vs. 11, p < 0.001; 9.6 vs. 6.0, p < 0.001). In multivariable analysis, surgery was an independent predictor of positive and negative patients' pre‐treatment expectations (all p ≤ 0.001). In thematic analysis, patients undergoing surgery emphasized distinct themes of pre‐treatment expectations. Patients undergoing surgery had higher mean PDQ symptom bother as well as higher psychological and physical symptom scores (14 vs. 10, p < 0.001; 9.2 vs. 7.1, p = 0.001). There were significant positive correlations between SETS negative expectation score and PDQ symptom bother (|ρ| = 0.25; p < 0.001) as well as PDQ psychological and physical symptoms score, respectively (|ρ| = 0.21; p = 0.001). Conclusion: PD patients expect both more benefit and more harm from surgery. In addition, patients undergoing surgery have more psychological and physical symptoms and more symptom bother. To set realistic expectations, it is of pivotal importance to assess patients' expectations before starting treatment. [ABSTRACT FROM AUTHOR]

Background: Testosterone plays an important role in collagen metabolism, transforming growth factor‐β1 expression, and wound healing, which are all critical factors in pathogenesis of Peyronie's disease. Some clinical studies have suggested an association between Peyronie's disease and hypogonadism. Objective: We sought to investigate whether baseline total testosterone levels influence response to intralesional collagenase clostridium histolyticum in Peyronie's disease. Methods: A retrospective review of patients receiving collagenase clostridium histolyticum injections with available total testosterone levels within 1 year of initial injection was conducted at a single institution. Baseline demographics, hypogonadal status, total testosterone, number of collagenase clostridium histolyticum cycles, and pre‐ and post‐treatment degrees of curvature were collected. Hypogonadism was defined as total testosterone <300 ng/dL. Results and discussion: Thirty‐six men were included with mean age of 58.2 years (SD 10.4) and mean body mass index 26.8 (SD 3.2). The mean total testosterone was 459.2 ng/dL (SD 144.0), and four (11.1%) were hypogonadal. Mean pre‐treatment curvature was 47.6°, and mean post‐treatment curvature was 27.8°, with mean improvement of 19.9° (40.1%). Hypogonadal status was not significantly associated with more severe curvature, 46.4° among hypogonadal men as to 57.5° among eugonadal men (p = 0.32). On linear regression analysis, total testosterone did not significantly predict improvement in degrees (β = –0.02; R2 = 0.06; p = 0.14) or percent (β = 0.0; R2 = 0.05; p = 0.18). Improvement in neither degrees nor percent differed significantly by hypogonadal status (p = 0.41 and 0.82, respectively). The cycle number did significantly predict greater improvement in curvature on both univariate and multivariate analyses (β = 5.7; R2 = 0.34; p < 0.01). Conclusion: Neither total testosterone nor hypogonadism is associated with a degree of improvement after collagenase clostridium histolyticum treatment. [ABSTRACT FROM AUTHOR]

This study aims to provide a comprehensive summary of the existing literature and conduct a systematic evaluation of the clinical outcomes associated with anterior controllable antedisplacement and fusion (ACAF) and posterior laminoplasty (LP) for the treatment of multisegment ossification of the cervical posterior longitudinal ligament (OPLL). We conducted an electronic search of databases, including PubMed, Embase, Cochrane Library, and CNKI, from the inception of the initial database to March 2023. We analyzed various parameters, including demographic data, operation time, intraoperative blood loss, cervical curvature, Japanese Orthopaedic Association (JOA) scores, Visual Analog Scale (VAS) scores, and postoperative complications. Two independent reviewers screened the literature, extracted data, and assessed the risk of bias in the included studies. Meta-analysis was performed using RevMan 5.4 software. Our evaluation encompassed 7 studies involving a total of 467 patients. The patient cohort was divided into 2 groups: Group A (ACAF) comprised 226 patients, while Group B (LP) comprised 241 patients. Overall, our statistical analysis revealed significant differences between the 2 groups (P < 0.05) in terms of intraoperative blood loss, operative time, JOA score, JOA score improvement rate, postoperative VAS score, postoperative cervical curvature, and the incidence of certain postoperative complications (C5 nerve root paralysis, dysphagia, and axial symptoms). However, there was no statistically significant difference in the incidence of postoperative cerebrospinal fluid leakage and postoperative total complications between the 2 groups (P > 0.05). The findings of this study suggest that, in the treatment of multilevel cervical OPLL, ACAF yields superior outcomes compared to LP. Specifically, ACAF improves postoperative neurologic function, reduces postoperative pain, lowers intraoperative blood loss, improves postoperative cervical curvature, and decreases the incidence of C5 nerve root paralysis and postoperative axial symptoms. Nonetheless, ACAF is associated with longer operative times and a higher incidence of postoperative dysphagia, though the overall incidence of postoperative complications is similar. It is important to note that these conclusions should be interpreted cautiously due to the limited sample size and the variable quality of the included studies. Further research involving larger, high-quality studies is warranted to validate these findings. [ABSTRACT FROM AUTHOR]

Background: Cavernous nerve (CN) injury, caused by prostatectomy and diabetes, initiates a remodeling process (smooth muscle apoptosis and increased collagen) in the corpora cavernosa of the penis of patients and animal models that is an underlying cause of erectile dysfunction (ED), and the Sonic hedgehog (SHH) pathway plays an essential role in the response of the penis to denervation, as collagen increases with SHH inhibition and decreases with SHH treatment. Aim: We examined if part of the mechanism of how SHH prevents penile remodeling and increased collagen with CN injury involves bone morphogenetic protein 4 (BMP4) and gremlin1 (GREM1) and examined the relationship between SHH, BMP4, GREM1, and collagen in penis of ED patients and rat models of CN injury, SHH inhibition, and SHH, BMP4, and GREM1 treatment. Methods: Corpora cavernosa of Peyronie's disease (control), prostatectomy, and diabetic ED patients were obtained (N = 30). Adult Sprague Dawley rats (n = 90) underwent (1) CN crush (1-7 days) or sham surgery; (2) CN injury and BMP4, GREM1, or mouse serum albumin (control) treatment via Affi-Gel beads or peptide amphiphile (PA) for 14 days; (3) 5E1 SHH inhibitor, IgG, or phosphate-buffered saline (control) treatment for 2 to 4 days; or (4) CN crush with mouse serum albumin or SHH for 9 days. Outcomes: Immunohistochemical and Western analysis for BMP4 and GREM1, and collagen analysis by hydroxyproline and trichrome stain were performed. Results: BMP4 and GREM1 proteins were identified in corpora cavernosa smooth muscle of prostatectomy, diabetic, and Peyronie's patients, and in rat smooth muscle, sympathetic nerve fibers, perineurium, blood vessels, and urethra. Collagen decreased 25.4% in rats with CN injury and BMP4 treatment (P = .02) and increased 61.3% with CN injury and GREM1 treatment (P = .005). Trichrome stain showed increased collagen in rats treated with GREM1. Western analysis identified increased BMP4 and GREM1 in corpora cavernosa of prostatectomy and diabetic patients, and after CN injury (1-2 days) in our rat model. Localization of BMP4 and GREM1 changed with SHH inhibition. SHH treatment increased the monomer form of BMP4 and GREM1, altering their range of signaling. Clinical implications: A better understanding of penile remodeling and how fibrosis occurs with loss of innervation is essential for development of novel ED therapies. Strengths and limitations: The relationship between SHH, BMP4, GREM1, and collagen is complex in the penis. Conclusion: BMP4 and GREM1 are downstream targets of SHH that impact collagen and may be useful in collaboration with SHH to prevent penile remodeling and ED. [ABSTRACT FROM AUTHOR]

Background Dupuytren's disease decreases quality of life significantly and often requires surgical treatment, nevertheless there is no actual gold standard. The aim of this study was to introduce the use of minimally invasive pull-through technique. Methods From 2016 to 2020, 52 patients suffering from Dupuytren's contracture were treated with the minimally invasive pull-through technique. We evaluated the improvement in range of motion, pain, disability, and quality of life in the long term. Total extension deficit, quick disabilities of the arm, shoulder, and hand (QuickDASH), and EuroQol five dimensions—five levels index were systematically scored before each surgical intervention and reevaluated after 24 months. Results Fourteen patients (26.9%) had already received a previous intervention (percutaneous needle aponeurotomy or collagenase Clostridium histolyticum). The mean preoperative total active extension deficit was 84.0 ± 23.3 degrees (55–130 degrees). Mean follow-up was 36 months. There were no cases of tendon rupture or neurovascular injury. Total active extension deficit at the final follow-up was 3.4 ± 2.3 degrees (0–12 degrees). The mean active range of motion of the MCP and PIP joints were, respectively, 90.5 ± 3.3 degrees (85–96 degrees) and 82.7 ± 2.5 degrees (80–87 degrees). At 24 months after cord excision, a mean 10.7 points improvement in the QuickDASH questionnaire was registered (p < 0.001). Pull-through technique was equally effective both on patients with a primary or a recurrent disease. Eight patients (15.4%) had a recurrence of disease in the metacarpophalangeal joint or proximal interphalangeal joint. Conclusion The pull-through technique is a simple, accessible, and effective technique for the treatment of Dupuytren's contracture. The use of palmar mini-incisions combined with minimal dissection has a low risk of iatrogenic injury to the neurovascular bundles and tendons, and has a low risk of recurrence rate. This study reflects level of evidence IV. [ABSTRACT FROM AUTHOR]

Erectile dysfunction (ED) is a common clinical condition that mainly affects men aged over 40 years. Various causes contribute to the progression of ED, including pelvic nerve injury, diabetes, metabolic syndrome, age, Peyronie's disease, smoking, and psychological disorders. Current treatments for ED are limited to symptom relief and do not address the root cause. Stem cells, with their powerful ability to proliferate and differentiate, are a promising approach for the treatment of male ED and are gradually gaining widespread attention. Current uses for treating ED have been studied primarily in experimental animals, with most studies observing improvements in erectile quality as well as improvements in erectile tissue. However, research on stem cell therapy for human ED is still limited. This article summarizes the recent literature on basic stem cell research on ED, including cavernous nerve injury, aging, diabetes, and sclerosing penile disease, and describes mechanisms of action and therapeutic effects of various stem cell therapies in experimental animals. Stem cells are also believed to interact with host tissue in a paracrine manner, and improved function can be supported through both implantation and paracrine factors. To date, stem cells have shown some preliminary promising results in animal and human models of ED. [ABSTRACT FROM AUTHOR]

To further evaluate extra-tunical grafting (ETG), a relatively new surgical option to treat corporal indentation in those with Peyronie's disease without buckling or hinge effect, we report our experience, patient satisfaction, and surgical outcomes. Retrospective review of patients following ETG, including pre-operative deformity, type of graft, graft location (under or over Buck fascia), patient characteristics, and satisfaction. Overall cosmetic satisfaction with deformity correction between patients undergoing 2 different ETG locations and 3 different types of grafts, as well as perceived bother of graft visibility and palpability were assessed. From 2018-2023, 35 patients underwent ETG and tunica albuginea plication (TAP) with 89.6% of patients having persistent correction on office examination at a median (interquartile range) follow-up of 23.5 (15.2) months. Overall satisfaction with penile appearance by grafting location via patient-reported questionnaires showed no statistical difference (P =.47). Patients undergoing TAP and ETG were satisfied with their erect appearance regardless of graft material. Patients reported grafting tissue was palpable (74.3%) and visible (48.6%) in the flaccid state as compared to the erect state (8.6% and 5.7%). ETG presents a less invasive surgical option than traditional approaches to correct indentation deformities not associated with instability. Our experience shows high patient satisfaction rate following correction of indentation using graft tissue when placed under or over Buck fascia. At a median follow-up of almost 2 years, patients had persistent correction, and while some report visibility of the graft and palpability in the flaccid state, this tends to disappear in the erect state.

Purpose: The purpose of this white paper is to educate health care professionals about the evolution of telemedicine (TM) and to propose a hybrid model that leverages the strengths of traditional in-person medicine as well as virtual medicine while maximizing the safety and quality of men's sexual health care. Literature Search Strategy: A literature search focused on the use of TM in urology and men's health was performed through PubMed/MEDLINE, Embase, and Web of Science (January 1, 2012–April 26, 2022). Keywords included all known permutations of the terminology used to refer to virtual health, care as well as the terminology used to refer to urologic diseases, issues specific to men's health, and men's sexual health concerns. Publications that emerged after the literature search that met this criterion also were incorporated. Opinion pieces, letters to the editor, meeting abstracts, and conference proceedings were excluded. Additional resources were retrieved, such as governmental technical reports, legislative updates and reviews, and blogs. This search strategy yielded 1684 records across databases after removal of duplicates. Abstracts from the retrieved records were reviewed for relevance. Relevant publications were defined as those that reported data on any aspect of TM use specific to urology, men's health, and/or men's sexual health. If relevance was unclear from the abstract, then the full text of the article was retrieved for a more detailed review. In addition, the published evidence-based practice guidelines relevant to care for erectile dysfunction, Peyronie's disease, ejaculatory dysfunction, and hypogonadism were retrieved. The most common reasons for article exclusions were a focus on TM use in disciplines other than urology and the absence of data (ie, opinion pieces). After exclusions, a total of 91 publications remained and constituted the evidence base for this paper. [ABSTRACT FROM AUTHOR]

Background: Transformation of resident fibroblasts to profibrotic myofibroblasts in the tunica albuginea is a critical step in the pathophysiology of Peyronie's disease (PD). We have previously shown that myofibroblasts do not revert to the fibroblast phenotype and we suggested that there is a point of no return at 36 hours after induction of the transformation. However, the molecular mechanisms that drive this proposed irreversibility are not known. Aim: Identify molecular pathways that drive the irreversibility of myofibroblast transformation by analyzing the expression of the genes involved in the process in a temporal fashion. Methods: Human primary fibroblasts obtained from tunica albuginea of patients with Peyronie's disease were transformed to myofibroblasts using transforming growth factor beta 1 (TGF-β1). The mRNA of the cells was collected at 0, 24, 36, 48, and 72 hours after stimulation with TGF-β1 and then analyzed using a Nanostring nCounter Fibrosis panel. The gene expression results were analyzed using Reactome pathway analysis database and ANNi, a deep learning–based inference algorithm based on a swarm approach. Outcomes: The study outcome was the time course of changes in gene expression during transformation of PD-derived fibroblasts to myofibroblasts. Results: The temporal analysis of the gene expression revealed that the majority of the changes at the gene expression level happened within the first 24 hours and remained so throughout the 72-hour period. At 36 hours, significant changes were observed in genes involved in MAPK-Hedgehog signaling pathways. Clinical Translation: This study highlights the importance of early intervention in clinical management of PD and the future potential of new drugs targeting the point of no return. Strengths and Limitations: The use of human primary cells and confirmation of results with further RNA analysis are the strengths of this study. The study was limited to 760 genes rather than the whole transcriptome. Conclusion: This study is to our knowledge the first analysis of temporal gene expression associated with the regulation of the transformation of resident fibroblasts to profibrotic myofibroblasts in PD. Further research is warranted to investigate the role of the MAPK-Hedgehog signaling pathways in reversibility of PD. [ABSTRACT FROM AUTHOR]

BackgroundAs perception of penile curvature varies widely, we sought to understand how adults perceive curvature and how these opinions compare with those of patients with curvature, specifically Peyronie's disease (PD).AimTo investigate the perspectives of curvature correction from adults with and without PD, as well as differences within demographics.MethodsA cross-sectional survey was administered to adult patients and nonpatient companions in general urology clinics at 3 institutions across the United States. Men, women, and nonbinary participants were recruited. Patients were grouped as having PD vs andrology conditions without PD vs general urology conditions plus companions. The survey consisted of unlabeled 2-dimensional images of penis models with varying degrees of curvature. Participants selected images that they would want surgically corrected for themselves and their children. Univariable and multivariable analyses were performed to identify demographic variables associated with willingness to correct.OutcomesOur main outcome was to detect differences in threshold to correct curvature between those with and without PD.ResultsParticipants were grouped as follows: PD (n = 141), andrology (n = 132), and general (n = 302) . Respectively, 12.8%, 18.9%, and 19.9% chose not to surgically correct any degree of curvature (P = .17). For those who chose surgical correction, the mean threshold for correction was 49.7°, 51.0°, and 51.0° (P = .48); for their children, the decision not to correct any degree of curvature was 21.3%, 25.4%, and 29.3% (P = .34), which was significantly higher than correction for themselves (P

Purpose: To investigate the efficacy of medical treatment options for Peyronie's disease (PD) including oral drugs, intralesional treatment and mechanical treatment compared with placebo treatment using network meta-analysis (NMA). Materials and Methods: We searched the randomized controlled trials (RCTs) of PD in PubMed, Cochrane library, and EMBASE up to October 2022. RCTs included medical treatment options: oral drugs, intralesional treatment and mechanical treatment. Studies reporting at least one of the outcome measures of interest including curvature degree, plaque size, and structured questionnaires (International Index of Erectile Function, IIEF) were included. Results: Finally, 24 studies including 1,643 participants met our selection criteria for NMA. There was no statistically significant treatment compared to placebo of the curvature degree, plaque size, IIEF in Bayesian analysis. The SUCRA values of ranking probabilities for each treatment performance, which indicated that hyperthermia device ranked first in NMA. However, in frequentist analysis, 7 of mono treatments (coenzyme Q10 [CoQ10] 300 mg, hyperthermia device, interferon alpha 2b, pentoxifylline 400 mg, propionyl-L-carnitine 1 g, penile traction therapy [PTT], vitamin E 300 mg) and 2 of combination treatments (“PTT–extracorporeal shockwave treatment”, “vitamin E 300 mg–propionyl-L-carnitine 1 g”) were statistically significant for improvement of curvature degree, and 9 of mono treatments (CoQ10 300 mg, hyaluronic acid 16 mg, hyperthermia device, interferon alpha 2b, pentoxifylline 400 mg, propionyl-L-carnitine 1 g, verapamil 10 mg, vitamin E 300 mg, vitamin E 400 U) and 3 of combination treatments ("interferon alpha 2b–vitamin E 400 U", "verapamil 10 mg–antioxidants", “vitamin E 300 mg–propionyl-L-carnitine 1 g”) were statistically significant in the improvement of plaque size. Conclusions: At present, there is no clinical treatment alternatives that have been demonstrated to be effective compared to placebo. Nonetheless, as the frequentist approach has shown that a number of agents are efficacious, further research is expected to develop more effective treatment options.

Characterization of Peyronie's disease (PD) involves manual goniometry and penile length measurement. These techniques neglect volume loss or hourglass deformities. Inter-provider variability complicates accuracy. Using 3D-printed models, we aimed to evaluate measurement accuracy and variability and establish computational assessment workflows. Five digital phantoms were created: 13.0 cm cylinder, 13.0 cm hourglass cylinder, 15.0 cm cylinder with 40° angulation, 12.0 cm straight penis, and 12.9 cm PD penis with 68° angulation and hourglass. Lengths, volumes, and angles were determined computationally. Each phantom was 3D-printed. Ten urology providers determined lengths, angles, and volumes with measuring tape, goniometer, and volume calculator. Provider versus computational measurements were compared to determine accuracy using t-tests or Wilcoxon rank-sum tests. No significant differences were observed between manual assessment of length of penile models and designed length in penile models. Average curvature angles from providers for bent cylinder and PD phantoms were 38.3° ± 3.9° (p = 0.25) and 57.5° ± 7.2° (p = 0.006), respectively. When assessing for volume, hourglass cylinder and bent cylinder showed significant differences between designed volume and provider averages. All assessments of length, angle, and volume showed significant provider variability. Our results suggest manual measurements suffer from inaccuracy and variability. Computational workflows are useful for improved accuracy and volume assessment.

Elastography is a noninvasive method that utilizes ultrasound imaging to assess the elasticity and stiffness of soft tissue. Peyronie's disease (PD) is a chronic inflammatory condition that affects the male penis, causing the formation of fibrous plaques. This alters the penis's elasticity and can lead to changes in its shape. Ultrasound elastography (UE) is an important advancement in the diagnosis of PD. It not only identifies plaques, but it also measures their rigidity, providing crucial information to monitor changes during and after treatment. We conducted a narrative review of the scientific literature to identify articles that discuss the use of elastography in the diagnostic study of PD. The purpose of this study was to describe the "state of the art" in the diagnostic use of ultrasound in combination with elastography to highlight any benefits in the diagnosis of PD. We found 12 relevant articles after searching PubMed, Embase, and Google Scholar using the keywords "ultrasound elastography" and "Peyronie's disease", including eight clinical studies, two case reports, and two review articles. The results of our review indicate that UE is a useful technique for identifying Peyronie-related plaques, particularly when they are not detectable using a standard ultrasound or physical examination. It is also helpful in monitoring improvements during and after conservative treatments. More research is required to confirm the effectiveness of ultrasound elastography in diagnosing Peyronie's disease and to determine whether it is better than traditional ultrasound.

Posterior single-door laminoplasty is a widely practiced clinical procedure, but the occurrence of postoperative axial syndrome (AS) remains a significant concern. The aim of this study was to identify risk factors associated with AS and develop a risk prediction model. Clinical data from 226 patients who underwent posterior single-door laminoplasty between June 2017 and June 2022 were collected. Through Logistic model analysis, the risk factors of AS are clarified and the intensity of each risk factor is explained in the form of forest plot. Subsequently, we constructed a predictive model and plotted receiver operating characteristic curves to assess the model's predictive value. In the end, 87 cases were diagnosed with AS, resulting in an incidence rate of 38.5%. Logistic regression analysis revealed that preoperative encroachment rate of anterior spinal canal (pre-op ERASC), intraoperative facet joints destruction, intraoperative open-door angle, postoperative loss of cervical curvature, and postoperative loss of cervical range of motion were independent risk factors for AS. Conversely, preoperative cervical curvature (pre-op CC) and postoperation early function training were protective factors against AS. The Youden index indicated that the cutoff values for pre-op ERASC and pre-op CC were 26.6°and 16.5, respectively. The risk prediction model for AS was constructed and a nomogram was plotted. The model has high clinical value. Pre-op ERASC, pre-op CC, intraoperative facet joints destruction, intraoperative open-door angle, postoperative loss of cervical curvature, postoperative loss of cervical range of motion, and postoperation early function training are independent influencing factors for AS occurrence. The risk model has good practicability. [ABSTRACT FROM AUTHOR]

Aim: Some recent studies on PD have focused on the WNT-2 and TGF-β1 gene loci, but its genetic basis is still not clearly known. In this context, we aimed to evaluate the presence of WNT-2 and TGF-β1 gene expression and genetic similarity between patients with Peyronie's disease (PD) and comorbidities, especially diabetes mellitus (DM). Methods: Between May 2020 and April 2021, 57 patients diagnosed with PD were included in this cross-sectional study. The presence of comorbidities [Dupuytren's contracture (DC), DM, hypertension (HT), dyslipidemia, and erectile dysfunction (ED)] was recorded. For genetic analysis, the WNT-2 and TGF-β1 genes were analyzed in the patients' serum. Results: The mean age was found to be 50.2. 45.6% of the patients had DM, 19.1% had HT, 14% had dyslipidemia, 5.3% had DC, and 40.4% had ED. TGF-β1 gene expression was found to be increased in all patients; WNT-2 gene expression was found to be increased in 80.7%. When subtypes of the TGF-β1 and WNT-2 gene expression were analyzed, 52.6% of patients with WNT-2 gene expression and 95.5% of patients with TGF-β1 gene expression were found to be homozygous, and the others were found to be heterozygous. Patients with DM and PD had significantly higher homozygous WNT-2 gene expression (p=0.03). No significant relationship was found between other comorbidities and these genes. Conclusion: Homozygous WNT-2 gene expression was found to be increased in PD with DM. These data could be used to explain the genetic pathophysiology of PD in diabetic patients.

Objective To investigate the impact of combining triamcinolone acetonide injections with negative pressure suction therapy on plaque size, pain, and outcomes in patients with penile induration (PD). Methods A retrospective analysis was conducted on the clinical data of 60 PD patients admitted to Suixi County Hospital from January 2018 to January 2023. They were divided into the control group (27 cases) and the study group (33 cases) by different treatment methods. The control group was treated with verapamil injection, and the study group was treated with triamcinolone acetonide injection combined with negative pressure suction therapy. The clinical efficacy, penile curvature, length, volume, plaque area, pain level, erectile function, adverse reactions, and recurrence rate of two groups of patients were compared. Results In comparision with the control group, the total effective rate of treatment in the study group was higher, with a statistically significant difference (P＜0.05). After treatment, the penile curvature in both groups was smaller than before treatment, and the length and volume were greater, in comparision with the control group, the penile curvature of the study group was smaller, and the length and volume were greater, with a statistically significant difference (P＜0.05). After treatment, the plaque area in both groups were smaller than before treatment, and the visual analogue scale (VAS) score was lower, in comparision with the control group, the plaque area of the study group was smaller, and the VAS score was lower, with a statistically significant difference (P＜0.05). The International Erectile Function Index Score-5 (IIEF-5) scores in both groups after treatment were higher than those before treatment, in comparision with the control group, the IIEF-5 scores of the study group after treatment were higher, with a statistically significant difference (P＜0.05). Conclusion The utilization of triamcinolone acetonide injection therapy in conjunction with negative pressure suction in the treatment of PD has been shown to enhance clinical effectiveness, reduce penile curvature, increase length and volume, decrease plaque area, alleviate pain, improve erectile function, and prevent adverse reactions or disease recurrence.

To determine change in the point of maximal curvature (POMC) during Collagenase Clostridium histolyticum (CCH) injections for Peyronie's disease (PD). A prospective database has been maintained of all men undergoing CCH injections since March 2014. For the current study, data were abstracted on the POMC with each curve assessment and correlated with demographic and clinical factors. Maximal changes were defined as the largest change in POMC from baseline. Six hundred and eighteen men underwent ≥1 series of CCH, with 313 having a baseline and subsequent POMC measurements available. Median baseline curvature was 60.0° and POMC 2.8 cm. Among 189 men who were satisfied or completed 8 CCH injections, the median improvement in penile curvature was −27.5° (40.9%). The median maximal change in POMC during CCH treatment was 1.0 cm (interquartile range, 0.5, 1.8). Overall, 55.6% had changes in POMC of ≥1 cm, 23.6% ≥2 cm, 8.9% ≥3 cm, and 3.8% ≥4 cm. Multivariate logistic regression identified ventral curvature as a predictor of larger change in POMC, after controlling for other variables. Study limitations included the observational, non-randomized study design and potential for intra- and inter-individual measurement variability. Strengths are the inclusion of an all-comer population, large series, prospective database, and routine objective assessments. Approximately half of men with PD undergoing CCH experience ≥1 cm of change in POMC during the treatment course, with nearly 1/4 experiencing ≥2 cm. Findings suggest that patients may benefit from repeat curvature assessments with each CCH series to optimize accuracy of drug administration. [ABSTRACT FROM AUTHOR]

Background: The efficacy and safety of collagenase Clostridium histolyticum (CCH) have been demonstrated in the treatment of men with Peyronie's disease (PD); however, the pivotal clinical trials excluded men with ventral penile curvature. Aim: The study sought to evaluate outcomes of CCH treatment in men with ventral curvatures secondary to PD. Methods: Men with PD treated with CCH were identified from a prospective database. Patients received up to 4 series of CCH injections using a progressively modified protocol over time. Results were compared between those with baseline ventral vs nonventral penile curvatures. Outcomes: Changes in penile curvature, Peyronie's Disease Questionnaire scores, International Index of Erectile Function scores, nonstandardized assessments, and adverse events. Results: A total of 560 men with PD (85 ventral curvature, 475 nonventral curvature) were included in the analysis. Baseline median curvature was 60.0° (interquartile range, 48.8°-75.0°) in the ventral cohort and 65.0° (interquartile range, 45.0°-80.0°) in the nonventral cohort. Median change from baseline penile curvature was −25.0° in the ventral cohort vs −24.0° in the nonventral cohort (P =.08, between-group comparison), which corresponded to curvature reductions of 44.7% and 33.6%, respectively (P =.03). In the subset of patients who completed CCH treatment (ie, received 8 injections or discontinued early because of patient satisfaction with curvature reduction), median change from baseline was −35.0° in the ventral cohort vs −25.0° in the nonventral cohort (P <.05); median percent improvement was 48.3% and 37.5%, respectively (P = .11). Median change from baseline in Peyronie's Disease Questionnaire and International Index of Erectile Function domain scores and adverse events were similar between cohorts, with the exception of possibly higher hematoma rates in the nonventral group (50% vs 37%; P = .05). No urethral injuries were sustained in either cohort. Clinical Implications: Data support the use of CCH for the treatment of ventral as well as nonventral penile curvatures in men with PD. Strengths and Limitations: Study strengths are the inclusion of a general clinical population of men with PD, the prospective design, and the relatively large series of men with ventral curvature. Limitations include the single-center and observational nature of the study. Conclusion: CCH was safe and effective in the treatment of both ventral and nonventral penile curvatures in men with PD.

Background: Plaque excision and grafting (PEG) has been recommended for patients with Peyronie's disease (PD) with >60° curvature and/or hinge effect and strong preoperative erections, while placement of an inflatable penile prosthesis (IPP) is recommended when rigidity is suboptimal. Nevertheless, many patients counseled to undergo an IPP decline and insist on proceeding with PEG due to personal preference or desire to avoid an implant. Aim: We aim to review long-term outcomes in patients who underwent PEG for PD at our institution and investigate whether there is any difference in long-term outcomes in patients who undergo PEG despite a recommendation to undergo IPP. Methods: We conducted a retrospective chart review from 2007 to 2021 on PEG surgery performed at a single tertiary care institution in patients ≥18 years old who had >3 months of follow-up. Outcomes: Postoperative information was gathered from the electronic medical record, including postoperative erectile function, patient satisfaction, and the ability to engage in penetrative sexual intercourse. Results: An overall 251 patients underwent PEG with a median follow-up of 12 months (IQR, 6-54). Among these, 54 (22%) were initially advised to undergo IPP but elected for PEG. Patients who underwent PEG despite counseling to undergo IPP reported lower postoperative ability to engage in intercourse (51% vs 76%). Seven (13%) patients initially advised to undergo IPP eventually received an IPP, relative to 7 (4%) initially advised to undergo PEG. Clinical Implications: Thorough preoperative assessment of erectile function and penile deformity can guide clinician counseling and manage patient expectations during decision making between PEG surgery and IPP implantation for PD. Strengths and Limitations: Limitations of this study include its retrospective nature, high attrition to follow-up, and risk of recall and selection bias. This is a large study with a median follow-up of 12 months, with a high-volume single surgeon who treats patients in a specialized population of complex cases. Conclusion: Patients who were initially counseled to undergo IPP due to suboptimal erectile rigidity but elected for PEG had worse postoperative ability to engage in penetrative intercourse, and a higher proportion of these patients eventually received an IPP.

Ledderhose disease (LD, or plantar fibromatosis) is a rare, nodular, hyperproliferative condition affecting the plantar aponeurosis of the foot. At present, several conservative, non-surgical treatments have been documented, although with various degrees of success, with little evidence in the literature supporting their efficacy. In this scenario, extracorporeal shock wave therapy (ESWT) has emerged as a safe, effective, and less invasive approach for the successful treatment of several refractory musculoskeletal conditions and soft tissue injuries. Again, recent experimental evidence has shown that ESWT can exert beneficial effects on different fibroproliferative diseases, including Dupuytren's and Peyronie's disease. In contrast, the literature regarding the use of ESWT for LD is extremely limited, and no optimal application parameters have been defined to ensure its effectiveness for this disease. Therefore, in the present paper, we report a case of a 48-year-old male patient who developed bilateral foot LD, which was successfully treated with a novel ESWT protocol of treatment consisting of three sessions at 1-week intervals, with 2000 impulses at 5 Hz with an energy flux density of 0.20 mJ/mm2. Our data show that this ESWT treatment protocol was effective in completely relieving pain, restoring full functional activity, and thus, greatly improving the patient's quality of life.

Background: Cell therapy (CT) is a form of regenerative medicine under investigation for the management of male sexual dysfunction (MSD). Aim: We sought to perform a systematic review of published information on CT for MSD and provide an official position statements for the European Society for Sexual Medicine. Methods: A comprehensive bibliographic search on the MEDLINE, Web of Science, Scopus, and Cochrane Library databases was conducted in February 2023. Articles were selected based on the Population, Intervention, Comparator, Outcome, Study design (PICOS) model if they included male patients (P) undergoing CT (I) with or without comparison with other treatments (C) and evaluated the impact of CT on sexual function (O). Quantitative data were reported as found in the original studies (S). Level of evidence and grade of recommendation according to the Oxford Centre for Evidence-Based Medicine were assigned to each statement. Outcomes: Outcomes were determined based on assessment of erectile function, ejaculatory function, orgasmic function, sexual desire, and penile curvature. Results: A total of 19 studies and 421 patients were included. Most articles (n = 12, 63%) were case series, whereas a minority of papers (n = 6, 32%) had a comparative group; only 2 articles reported randomized controlled trials (RCTs) and 1 article reported a post hoc analysis of RCTs. Most articles (16, 84%) investigated patients with erectile dysfunction (ED). Improvements in the International Index of Erectile Function–Erectile Function Domain (IIEF-EF) or the IIEF 5-item version (IIEF-5) were found in 11/15 (73%) studies, with mean increases in IIEF-EF, mean IIEF-5, and median IIEF-EF between 8 and 14 points, 2 and 9 points, and 4.5 and 6 points, respectively. Two papers (20%) evaluated men with Peyronie's disease (PD). In both ot these articles penile curvature improvement and plaque volume reduction were described in all patients (n = 16, 100%). Objective measurements were performed in 1 study, which showed 10°-120° (15%-100%) curvature improvement and 90%-100% plaque reduction. Mild transient adverse events at the donor or administration sites were found in 7/16 (44%) papers on ED. Priapism was reported in one case (20%) and mild penile skin complications were reported in the majority of patients after CT for PD. No severe adverse events were described. Clinical Implications: Although high-quality evidence is lacking, CT appears to have potential benefits from application in patients with ED or PD. Strengths and Limitations: This report is to our knowledge the most comprehensive and up-to-date systematic review on the topic of CT for the management of MSD, including the position statements of the European Society for Sexual Medicine. Overall the assessment of available studies demonstrated low quality and significant heterogeneity. Conclusion: Preliminary findings support potential efficacy and safety of CT in patients with ED or PD. Low-quality papers, high methodological heterogeneity, uncertainty about the magnitude of the beneficial effects, and lack of long-term data limit the available evidence. [ABSTRACT FROM AUTHOR]

To evaluate risk factors leading to corporal rupture after Collagenase Clostridium histolyticum (CCh). Peyronie's disease (PD) is a fibrotic condition of the penis characterized by abnormal plaque formation. Intralesional CCh is the only FDA-approved medication for PD, however, it can lead to corporal rupture, a potential surgical emergency. We retrospectively reviewed medical records from Veterans diagnosed with PD who were under treatment with CCh using the Veterans Administration Informatics and Computing Infrastructure (VINCI). Using International Classification of Diseases and Current Procedural Terminology codes, we identified men who suffered a corporal rupture after CCh. Individual charts were reviewed to determine potential risk factors and events leading to corporal rupture. We identified 17,647 veterans who were diagnosed with PD, of which 8.7% (1541) received at least one injection of CCh for PD. Of them, 0.7% (11/1541) veterans suffered corporal rupture. Within these 11 patients, the median number of CCH injections was 6 with a median initial curvature of 35°. Fracture occurred at a median of 8 days after CCH injection. The majority of fractures were secondary to spontaneous erections or sexual intercourse. Finally, six patients had their fracture repaired surgically while the remaining were managed conservatively. Most fractures occurred within 2 weeks of CCh injections and were associated with sexual intercourse and spontaneous morning erections. [ABSTRACT FROM AUTHOR]
