RESUMO
Chromophobe RCC (ChRCC) carries the best prognosis among all RCC subtypes, yet it lacks a proper grading system. Various systems have been suggested in the past, causing much controversy, and Avulova et al. recently proposed a promising four-tier grading system that takes into consideration tumor necrosis. Dysregulation of the mammalian target of the rapamycin (mTOR) pathway plays a key role in ChRCC pathogenesis, highlighting its molecular complexity. The present retrospective study aimed to evaluate the prognostic factors associated with a more aggressive ChRCC phenotype. Materials and Methods: Seventy-two patients diagnosed with ChRCC between 2004 and 2017 were included in our study. Pathology reports and tissue blocks were reviewed, and immunohistochemistry (IHC) was performed in order to assess the expressions of CYLD (tumor-suppressor gene) and mTOR, among other markers. Univariate analysis was performed, and OS was assessed using the Kaplan-Meier method. Results: In our study, 74% of patients were male, with a mean age of 60 years, and the mean tumor size was 63 mm (±44). The majority (54%) were followed for more than 10 years at intervals ranging between 44 and 222 months. The risk of death was significantly higher for patients that were classified as Grade 4 in the Avulova system (HR: 5.83; 95% CI, 1.37-24.7; p: = 0.017). As far as the IHC is concerned, mTOR expression was associated with an HR of 8.57 (95% CI, 1.91-38.5; p = 0.005), and CYLD expression was associated with an HR of 17.3 (95% CI, 1.57-192; p = 0.02). Conclusions: In our study, the Avulova grading system seems to be positively correlated with OS in patients diagnosed with ChRCC. Furthermore, an elevated mTOR expression also shows a negative correlation with OS, whereas an elevated CYLD expression does not seem to exert a protective role. However, because only a small proportion (4.2%) of our patients died due to ChRCC, despite the long follow-up period, the results must be interpreted with caution. Further research is needed to validate our findings.

OBJECTIVES: In women with systemic autoimmune rheumatic diseases (SARDs), female sexual dysfunction (SD) remains underestimated. We aimed to explore the prevalence and correlates of SD in females with SARDs. METHODS: We performed a systematic review and meta-analysis of studies assessing the prevalence of SD and the pooled Female Sexual Function Index (FSFI) scores in this setting (PROSPERO: CRD42021287346). We searched PubMed, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) databases and grey literature until February 2022. We evaluated the quality of the selected records using the Hoy Risk of Bias tool. A random-effects meta-analysis of proportions with the double arcsine transformation was conducted. Subgroup and sensitivity analyses, as well as meta-regression of important correlates, were conducted. RESULTS: We included 68 studies with 5457 females diagnosed with a SARD (mean age: 43.7 [12.9] years). The overall SD prevalence was 63% (95% CI: 56, 69%, I2 = 94%) and the overall FSFI total score was 19.7 points (95% CI: 18.4, 21, I2 = 97%). Including only sexually active females, the SD prevalence was estimated as 60% (95% CI: 53, 67%, I2 = 88%), whereas the FSFI total score was 22 points (95% CI: 20.8, 23.1, I2 = 93%). Across the different SARDs, women with Sjögren's syndrome and systemic sclerosis reported the highest levels of SD (74%, 95% CI: 58, 87%, I2 = 84% and 69%, 95% CI: 54, 83%, I2 = 94%, respectively). CONCLUSION: Sexual function in females with SARDs seems to be severely impaired, irrespective of the type of SARD. Screening and treatment of SD in females with SARDs should become an integral part of healthcare clinical practice.

BACKGROUND: The PICS technique (penile implant in combination with the sealing) was recently described as a valuable option to correct residual curvature during inflatable penile prosthesis (IPP) implantation in patients with complex Peyronie disease (PD). AIM: To report the surgical and functional outcomes of the PICS technique in a multicentric series of patients. METHODS: A consecutive series of patients with complex PD who underwent PICS were recruited. Patients were from 2 European tertiary referral centers. Data regarding baseline characteristics and perioperative, postoperative, and functional outcomes were retrospectively evaluated. OUTCOMES: Complete penile straightness, duration of operative time and hospital stay, as well as postoperative complications (including hematoma, IPP infection, and IPP mechanical failure) were recorded, whereas functional outcomes were evaluated through the administration of validated questionnaires at baseline and 12 months postoperatively: International Index of Erectile Function-5, Sexual Encounter Profile questions 2 and 3 (SEP-2 and SEP-3), and Erectile Dysfunction Inventory of Treatment Satisfaction. RESULTS: Thirty-seven patients with a median age of 62 years (IQR, 57-70 years) were enrolled. Median preoperative curvature was 75° (IQR, 65°-77°). Median residual curvature after IPP implantation was 60° (IQR, 50°-70°). Overall, 31 patients (84%) achieved a totally straight penis. Only 6 patients (16%) experienced a residual penile curvature (<20° in all cases) after the procedure. No intraoperative complications were detected. Nine patients (24%) developed an early postoperative complication, 3 (8%) a transient fever, and 6 (16%) a genital hematoma. A single case of IPP acute infection requiring device explantation was recorded. The survey response rate was 100%. At the 12-month follow-up evaluation, the median IIEF-5 score was 23.5 (IQR, 22.2-25) with evident improvement vs the baseline value of 10 (IQR, 8-12). Accordingly, 92% of the patients responded positively to SEP-2 and SEP-3. For the Erectile Dysfunction Inventory of Treatment Satisfaction, patients recorded a median postoperative value of 25 (IQR, 21-30) 1 year after PICS. CLINICAL IMPLICATIONS: Complex PD is an end-stage disease featured by severe penile curvature, penile shortening, and erectile dysfunction: the gold standard approach is deemed to be penile prosthesis implantation, aiming to address penile curvature and erectile dysfunction, but in a limited percentage of cases, additional maneuvers are deemed necessary to manage residual penile curvature. STRENGTHS AND LIMITATIONS: Our study has some limitations: the retrospective nature, relatively short follow-up, and limited number of patients. CONCLUSION: The PICS technique may represent a reliable and effective treatment option to address significant residual curvature after IPP implantation.

PURPOSE: To explore the impact of ileal conduit (IC), orthotopic ileal neobladder, and MAINZ Pouch I on renal function (RF) over time. METHODS: We performed a retrospective, cohort study including consecutive patients who underwent open radical cystectomy due to bladder cancer from November 2013 to June 2022. RF deterioration was calculated based on the estimated glomerular filtration rate (eGFR) through the CKD-EPI creatinine equation. A linear mixed-effects model was constructed, adjusting for multiple risk factors. The probability of achieving an eGFR reduction greater than 25% compared to baseline among different urinary diversion techniques was assessed using a Kaplan-Meier curve. RESULTS: Overall, 107 patients received IC, 28 neobladder, and 20 MAINZ Pouch I. Those receiving IC were older and displayed more comorbidities. At follow-up, eGFR was lower by 0.09 mL/min/1.73m2 (confidence interval - 5.87 to 5.69, p = 0.975) in patients receiving neobladder compared to those receiving IC. Similarly, eGFR was higher by 4.64 mL/min/1.73m2 (confidence interval - 1.57 to 10.85, p = 0.143) in patients receiving pouch compared to those receiving IC. Accordingly, patients with higher preoperative eGFR (p < 0.001), lower age (p = 0.048), non-T4 histological tumor (p = 0.027) and absence of septicemia at follow-up (p = 0.002) presented higher eGFR values at follow-up. The three UD techniques did not differ significantly in the time-to-event analysis (log-rank test = 0.29). CONCLUSIONS: A substantial proportion of patients undergoing urinary diversion with IC, orthotopic ileal neobladder, or MAINZ Pouch I develop RF deterioration at follow-up. No significant differences were observed among the three UD techniques in terms of eGFR decline in the long-term.

PURPOSE: We describe the sealing technique with collagen fleece in patients with advanced Peyronie's disease (PD) and provide the prospective long-term outcomes. MATERIALS AND METHODS: We performed a multicenter cohort study in patients with preserved erectile function and stable PD that precluded sexual intercourse. All patients underwent partial plaque excision with collagen fleece grafting. The applied technique is explained through a high-quality video accompanied by relevant animations. After hospital discharge, all patients were assessed at 1, 4 and 24 weeks after treatment. Subsequently, they presented for an additional long-term evaluation. RESULTS: From December 2004 to June 2015, 367 patients underwent surgery. Of these, 319 (86.9%) presented for the long-term evaluation and were included in the present study. At a median operative time of 79.8 minutes (range 50-130), total straightness of the penis was achieved in 299 cases (93.7%) and mean±SD penile length increased by 1.1±0.6 cm (p=0.017). After a median followup of 47.2 months (range 12-100), 291 patients (91.2%) presented with complete penile straightness. The penile glans sensation returned to the preoperative levels in 300 cases (94%). Only 11 cases of treatment-related grade 1 Clavien-Dindo complications were reported. Erectile function improved in 78 participants (24.5%) and remained unchanged in 191 (59.8%), whereas it was worsened in 50 (15.7%). Overall, the patient satisfaction rate was 87.8% and the partner satisfaction rate was 84.3%. CONCLUSIONS: Grafting with collagen fleece in patients with advanced PD is a safe and effective procedure that reduces operative time, provides an additional hemostatic effect and represents a cost-effective technique.

PURPOSE: Erectile dysfunction has a lower prevalence in renal transplant recipients compared to dialysis patients. Despite this observation, the effect of renal transplantation on erectile function remains unknown. We aimed to assess the role of renal transplantation on erectile function and to determine potential factors improving or deteriorating erectile dysfunction. MATERIALS AND METHODS: We conducted a systematic review and random effects meta-analysis of observational studies comparing erectile function preoperatively and postoperatively in renal transplant recipients (PROSPERO ID: CRD42020189580). Records reporting relevant outcomes were identified through search of PubMed®, Embase®, Cochrane Library and Scopus® databases from inception to September 2020. Judgment of the strength of evidence was performed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: We included 20 studies with 1,695 renal transplant recipients. At postoperative evaluation the number of patients with erectile dysfunction was reduced (RR 1.21, 95% CI 1.02-1.45, I2=88%). Renal transplant recipients reported an improvement in erectile function (RR 2.53, 95% CI 1.44-4.44, I2=90%) and the mean International Index of Erectile Function score increased by 3.04 points (95% CI 0.63-5.45, I2=96%) after renal transplantation. These effects were not demonstrated in the sensitivity analysis. In individuals reporting severe erectile dysfunction, no favorable effect of renal transplantation was observed (RR 1.51, 95% CI 0.85-2.68, I2=33%). For all outcomes the strength of evidence was considered low or very low due to methodological concerns and high heterogeneity among the included studies. CONCLUSIONS: Renal transplantation improves erectile function and the risk of erectile dysfunction reduces postoperatively compared to preoperatively. However, evidence on the matter is mostly based on low quality data. More studies with standardized outcomes are needed to validate and strengthen our findings.

OBJECTIVES: To perform a systematic review and meta-analysis aiming to improve the level of evidence and determine the efficacy and safety of low-intensity shockwave therapy (LiST) in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: We searched PubMed, Cochrane Library and Scopus databases from inception to November 2020 for randomised controlled trials (RCTs) exploring the role of LiST for the management of CP/CPPS. We performed a random-effects meta-analysis of RCTs comparing LiST vs sham therapy on CP/CPPS symptoms at different time-points after treatment. Weighted mean differences (WMDs) with the corresponding confidence intervals (CIs) were estimated. Furthermore, we assessed the strength of evidence with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system (International Prospective Register of Systematic Reviews [PROSPERO]: CRD42020208813). RESULTS: We included five sham RCTs and one non-sham RCT. In the meta-analysis of sham RCTs, both the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) pain domain score and the numeric pain rating scale improved significantly after LiST vs sham therapy at the assessment directly after treatment protocol completion (WMD 3.2, 95% CI 0.88-5.52, I2 = 90%; and WMD 1.43, 95% CI 0.85-2.01, I2 = 32%, respectively), at 1 month (WMD 4.4, 95% CI 2.84-5.95, I2 = 68%, and WMD 2.59, 95% CI 1.92-3.27, I2 = 83%, respectively), and at 3 months after last treatment session (WMD 3.61, 95% CI 1.49-5.74, I2 = 90%, and WMD 2.64, 95% CI 2.13-3.16, I2 = 71%, respectively). Similarly, the NIH-CPSI total and quality-of-life domain scores improved significantly after LiST compared to sham therapy for the same time-points. Conversely, the long-term efficacy of LiST, as well as the effect of LiST on lower urinary tract symptoms and erectile function, was clinically insignificant. CONCLUSIONS: LiST is an effective treatment modality for the improvement of pain and quality of life in patients with CP/CPPS. Therefore, it should be recommended as a part of individualised treatment strategies in such patients.

BACKGROUND: In women with end-stage renal disease (ESRD), female sexual dysfunction (SD) remains underestimated. AIM: To explore the prevalence, correlates, diagnostic approach and treatment modalities of sexual symptoms in females with ESRD. METHODS: We performed a systematic review and meta-analysis to estimate both the prevalence of SD and the pooled Female Sexual Function Index (FSFI) scores in ESRD females. Similarly, for studies reporting the FSFI score before and after renal transplantation (RT), we estimated the effect of RT on sexual function. Further assessment of heterogeneity was conducted via subgroup and sensitivity analyses, cumulative meta-analysis and univariate meta-regression of important correlates. Records were identified through searching PubMed, Cochrane Library and Scopus databases as well as sources of grey literature until November 2020 (PROSPERO ID: CRD42020215178). OUTCOMES: We included 47 studies with 61 patient group entries and 3490 ESRD female individuals (median age: 45.2 years, ΙQR: 40.4-50.6). RESULTS: The SD prevalence in all females with ESRD was 74% (95%CI: 67%-80%, I2 = 92%) and the FSFI total score 16.1 points (95%CI: 14.3-17.8, I2 = 98%). The female SD prevalence was 63% (95%CI: 43%-81%, I2 = 92%) in renal transplant recipients, 80% (95%CI: 72%-87%, I2 = 91%) in hemodialysis patients and 67% (95%CI: 46%-84%, I2 = 90%) in peritoneal dialysis patients. The total FSFI score improved by 7.5 points (95%CI: 3.9-11.1, I2 = 92%) after RT. Older age and menopause were associated with higher SD prevalence. CLINICAL TRANSLATION: Female SD is highly prevalent in all ESRD women, but renal transplant recipients reported improved sexual function. STRENGTHS & LIMITATIONS: We provide the first study about SD in females and assessed the role of RT on sexual function. Contrary, none of the included studies evaluated the concomitant presence of distress with SD. The levels of heterogeneity were substantially high for all outcomes and we could not adjust for further correlates, which might have affected our measures. CONCLUSIONS: Sexual symptoms negatively affect the quality of life and warrants appropriate clinical attention, as they are an underdetermined and undertreated clinical entity in females with ESRD. Studies on treatment modalities of female SD in patients with ESRD are mandatory, as currently no relevant studies or clinical recommendations exist. Pyrgidis N, Mykoniatis I, Tishukov M, et al.

PURPOSE: To explore the usability and diagnostic accuracy for prostate cancer of three multiparametric magnetic resonance imaging (mpMRI)/transrectal ultrasound (TRUS)-guided fusion biopsy systems operated by the same urologists. METHODS: We performed a prospective, observational study including patients that underwent prostate biopsy due to a visible lesion in mpMRI (PI-RADS ≥ 3). We consecutively assessed two platforms with a rigid image registration (BioJet, D&K Technologies and UroNav, Invivo Corporation) and one with an elastic registration (Trinity, KOELIS). Four urologists evaluated each fusion system in terms of usability based on the System Usability Scale and diagnostic accuracy based on the detection of prostate cancer. RESULTS: We enrolled 60 consecutive patients that received mpMRI/TRUS-guided prostate biopsy with the BioJet (n = 20), UroNav (n = 20) or Trinity (n = 20) fusion system. Comparing the rigid with the elastic registration systems, the rigid registration systems were more user-friendly compared to the elastic registration systems (p = 0.012). Similarly, the prostate biopsy with the rigid registration systems had a shorter duration compared to the elastic registration system (p < 0.001). Overall, 40 cases of prostate cancer were detected. Of them, both the BioJet and UroNav fusion systems detected 13 prostate cancer cases, while the Trinity detected 14. No significant differences were demonstrated among the three fusion biopsy systems in terms of highest ISUP Grade Group (p > 0.99). CONCLUSIONS: Rigid fusion biopsy systems are easier to use and provide shorter operative time compared to elastic systems, while both types of platforms display similar detection rates for prostate cancer. Still, further high-quality, long-term results are mandatory.

PURPOSE: We evaluated the role of magnetic resonance imaging of the penis in the diagnosis of penile fracture and/or concomitant urethral lesions in real-life emergency settings compared with intraoperative findings. MATERIALS AND METHODS: A total of 43 patients presented with suspicion of penile fracture between January 2006 and December 2016. Magnetic resonance imaging was performed in 28 patients prior to surgical treatment in the emergency setting. Surgery was done in all patients via a subcoronal, circumferential degloving approach. We calculated sensitivity, specificity, and positive and negative predictive values as well as likelihood ratios of the positive and negative results of the agreement between magnetic resonance imaging and intraoperative findings. RESULTS: Intraoperatively penile fracture was confirmed in 19 of 28 patients (67.9%) and a concomitant urethral lesion was observed in 5 of 28 (17.9%). Magnetic resonance imaging findings were highly associated with intraoperative findings of tunical rupture, including 100% sensitivity (95% CI 98.5-100), 77.8% specificity (95% CI 50.6-100), 90.5% positive predictive value (95% CI 78-100), 100% negative predictive value (95% CI 97.6-100) and a positive result likelihood ratio of 4.5. Magnetic resonance imaging had lower accuracy for urethral lesions with 60% sensitivity (95% CI 17.1-100), 78.3% specificity (95% CI 61.5-95.1), 37.5% positive predictive value (95% CI 4-71), 90% negative predictive value (95% CI 76.9-100) and a positive result likelihood ratio of 2.76. CONCLUSIONS: Magnetic resonance imaging may be applicable in the emergency setting if the goal is to treat all men who warrant intervention. It has high sensitivity and negative predictive value for tunical rupture and concomitant urethral lesions. Therefore, it could help avoid unnecessary surgery by excluding the diagnosis. However, solitary magnetic resonance imaging is not sufficient for diagnosis and it should not replace clinical assessment or delay surgical exploration.

INTRODUCTION: Despite recent promising clinical results, the underlying mechanism of action of low-intensity extracorporeal shockwave therapy (Li-ESWT) for erectile dysfunction (ED) is mostly unclear and currently under investigation. AIM: To systematically identify and evaluate evidence regarding the basic science behind Li-ESWT for ED, discuss and propose a putative mechanism of action, address the limitations, and imply insights for further investigation in the field. METHODS: Using Cochrane's methodologic recommendations on scoping studies and systematic reviews, we conducted a systematic scoping review of the literature on experimental research regarding Li-ESWT for ED and other pathologic conditions. The initial systematic search was carried between January and November 2017, with 2 additional searches in April and August 2018. All studies that applied shockwave treatment at an energy flux density >0.25 mJ/mm2 were excluded from the final analysis. MAIN OUTCOME MEASURE: We primarily aimed to clarify the biological responses in erectile tissue after Li-ESWT that could lead to improvement in erectile function. RESULTS: 59 publications were selected for inclusion in this study. 15 experimental research articles were identified on Li-ESWT for ED and 44 on Li-ESWT for other pathologic conditions. Li-ESWT for ED seems to improve erectile function possibly through stimulation of mechanosensors, inducing the activation of neoangiogenesis processes, recruitment and activation of progenitor cells, improving microcirculation, nerve regeneration, remodeling of erectile tissue, and reducing inflammatory and cellular stress responses. CLINICAL IMPLICATIONS: Improving our understanding of the mechanism of action of Li-ESWT for ED can help us improve our study designs, as well as suggest new avenues of investigation. STRENGTHS & LIMITATIONS: A common limitation in all these studies is the heterogeneity of the shockwave treatment application and protocol. CONCLUSION: Li-ESWT for ED, based on current experimental studies, seems to improve erectile function by inducing angiogenesis and reversing pathologic processes in erectile tissue. These studies provide preliminary insights, but no definitive answers, and many questions remain unanswered regarding the mechanism of action, as well as the ideal treatment protocol.

PURPOSE: The study aimed to evaluate the impact of the validated functional dexterity test and the Mini-Mental Status test on subjective functional outcomes, medical care situation, and health-related quality of life (HRQoL) after urinary diversion (UD). PATIENTS AND METHODS: A total of 106 patients (n = 26 ileal conduits, n = 29 neobladders, and n = 51 ileocecal pouches) were included in this combined retrospective (n = 77) and prospective (n = 29) observational study. All patients performed the 2 tests mentioned above and filled out self-designed questionnaires with diversion and HRQoL items. In the prospective cohort, the tests were performed preoperatively and the questionnaires were filled out preoperatively as well as 3 and 6 months after surgery. RESULTS: Reduced dexterity and cognitive skills were significantly associated with increased patient age and subjective constraints in stoma care of ileal conduits, self-catheterization in ileocecal pouches, and continence in neobladders. Overall HRQoL, however, was not affected by dexterity or cognitive measures. CONCLUSIONS: Assessing the cognitive status and functional dexterity of patients undergoing UD might provide a useful objective clinical tool to aid in decision-making regarding the type of UD and postoperative medical care situation. Further prospective data are needed to confirm these findings and further simplify the methods used here.

Saphenous vein graft (SVG) aneurysms (SVGA) after renal transplantation represents a rare vascular complication with subsequent challenging multidisciplinary treatment. We present a case of a 30-year-old female who received a live donor kidney transplantation for end-stage renal disease that was caused due to the hemolytic uremic syndrome. Postoperatively, an insufficient graft perfusion due to an arterial kinking was noted and repaired using an autologous SVG interposition. Ten years later, a 3-cm aneurysm of the SVG at the anastomotic site with the common iliac artery was discovered. Multidisciplinary surgical exploration with excision of the aneurysm-carrying vein graft and interposition of a new autologous SVG was successfully carried out with preservation of renal allograft's function. Treatment of SVGA after rental transplantation with a new autologous SVG is challenging but feasible, requiring a multidisciplinary approach in order to guarantee successful rates and to prevent allograft loss.

PURPOSE: To validate preoperative C-reactive protein (CRP) levels as a prognostic marker for survival in a metastasized renal cell carcinoma (mRCC) patient cohort receiving cytoreductive nephrectomy (CN). PATIENTS AND METHODS: By chart review, 146 mRCC patients receiving CN at our tertiary referral centre from 1997 to 2015 were identified retrospectively. All relevant clinicopathological features including laboratory parameters were collected and correlated to overall survival, progression-free survival and cancer-specific survival (CSS). The mean follow-up was 23 months (range 1-168 months). RESULTS: Besides the already established scoring systems like the MSKCC criteria, an elevated preoperative CRP level (≥0.5 mg/dL) was an independent predictor of CSS in our study group including the chosen postoperative adjuvant therapies (TKI vs. immunotherapy vs. others). With regard to morbidity, patients with a good performance status, small tumour size and adequate renal function/haematopoiesis experienced less complication rates, thereby profiting more from CN. CONCLUSIONS: Our data provide indication that preoperative CRP levels should be implemented in nomograms regarding the outcome prediction in mRCC to identify candidates likely to profit from CN.

Background: Penile shortening, frequently resulting from end-stage Peyronie's disease (PD), has a negative impact on patients' sexual activity and overall quality of life, especially when accompanied by Erectile dysfunction (ED). Various surgical techniques have been described to manage concomitant ED and penile shortening through penile prosthesis (PP) implantation. Objectives: To evaluate the benefits and risks of different penile length preservation techniques during PP implantation. Design: A systematic review of the available literature on the use of penile length preservation maneuvers in conjunction with PP implantation was conducted. Data sources and methods: For this systematic review, three databases (Medline, Embase and Cochrane) and clinical trial.gov were queried for relevant publications from 1 January 1990 to 1 September 2022. The review process followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results: The qualitative analysis included 15 relevant articles involving 1186 adult patients who underwent penile length preservation techniques during PP implantation. Penile lengthening of 1-7 cm was reported. Overall, postoperative complications were described in up to 21.7% of cases. Only five studies reported functional outcomes, showing a significant improvement in postoperative period based on the administered questionnaire (e.g. IIEF - International Index of Erectile Function, EDITS - Erectile Dysfunction Inventory of Treatment Satisfaction). Conclusion: Penile length preservation procedures appear to offer a viable option for managing acquired penile shortening, particularly in cases of PD. However, they are associated with a significant risk of complications. Proper patient selection, thorough discussion of risks and benefits, and referral to high-volume centers are mandatory to achieve optimal outcomes and minimizing complications. Trial registration: PROSPERO database registration CRD42022360758.
RESUMO
PURPOSE: Augmented adiposity may negatively impact sexual sphere through its metabolic effects and its detrimental impact on reproductive hormones. Moreover, a dysregulated metabolic pathway may promote apoptosis among spermatogenic cells. Based on these premises, a relation between weights loss and ameliorate semen parameters seems beneficial. To investigate if physical activity may affect semen parameters and fertility rate, a systematic literature search on major dataset has been performed. MATERIALS AND METHODS: The search terms included: "Assisted reproduction therapies," "fertility," "semen parameters," "sperm parameters," and "physical activity." This analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines and it was registered on PROSPERO (CRD42023384471). A total of 47 studies have been identified; 1 reference has been eliminated after duplication check. After preliminary screening 32 papers have been excluded. Considering the exclusion criteria, 15 full-text articles were evaluated for eligibility. After a full-text review, six studies published during a span of eight years (2014-2022) have been included in the meta-analysis. Semen parameters, pregnancy and birth rates were investigated. The revised Cochrane risk of bias tool (Rob2) has been used to check the risk of bias. RESULTS: The number of patients enrolled in studies ranges from 17 to 521; in the end, a total of 1,637 patients have been enrolled in the study. Fertility parameters investigated were semen quality parameters and pregnancy rates and live births. A statistically significant relationship between physical exercise and sperm concentration (p=0.02), total sperm motility (p<0.01), total sperm count (p<0.01), normal morphology (p<0.01) has been established. Moreover, the study registered a statistically significant association within physical activity and total pregnancy rate (p<0.01) and live birth rate (p<0.01). CONCLUSIONS: We demonstrated that physical activity is significantly associated with amelioration of semen parameters and may be crucial in improving or even reverting male infertility.
RESUMO
Conditions referred to as 'male sexual dysfunctions' usually include erectile dysfunction, ejaculatory disorders and male hypogonadism. However, some less common male sexual disorders exist, which are under-recognized and under-treated, leading to considerable morbidity, with adverse effects on individuals' sexual health and relationships. Such conditions include post-finasteride syndrome, restless genital syndrome, post-orgasmic illness syndrome, post-selective serotonin reuptake inhibitor (SSRI) sexual dysfunction, hard-flaccid syndrome, sleep-related painful erections and post-retinoid sexual dysfunction. Information about these disorders usually originates from case-control trials or small case series; thus, the published literature is scarce. As the aetiology of these diseases has not been fully elucidated, the optimal investigational work-up and therapy are not well defined, and the available options cannot, therefore, adequately address patients' sexual problems and implement appropriate treatment. Thus, larger-scale studies - including prospective trials and comprehensive case registries - are crucial to better understand the aetiology, prevalence and clinical characteristics of these conditions. Furthermore, collaborative efforts among researchers, health-care professionals and patient advocacy groups will be essential in order to develop evidence-based guidelines and novel therapeutic approaches that can effectively address these disorders. By advancing our understanding and refining treatment strategies, we can strive towards improving the quality of life and fostering healthier sexual relationships for individuals suffering from these rare sexual disorders.

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.
