This study aimed to evaluate lengthening corporoplasty outcomes using a graft of collagen fleece in Portugal. A multicentric retrospective study included PD patients who underwent the procedure between 2016 and 2024 at four Portuguese hospitals. Among 88 patients, the median age (IQR) was 59.0 (56.0-63.0) years, International Index of Erectile Function-5 (IIEF-5) score 22.5 (22.0-23.0), stretched penile length (SPL) 13.0 (12.0-14.0) cm, and curvature angle 80.0° (78.8-90.0)°. Dorsal curvature was most common (65.9%) and the median surgery duration was 92.5 (80.0-106.3) min. Early postoperative hematoma occurred in 8.0% of cases, and 2.3% had surgical site infections. No surgical reinterventions were needed. After a median follow-up of 31 months, complications included erectile dysfunction (38.6%), residual curvature (19.3%), reduced penile length (9.1%), penile pain (8.0%), and glans hypoesthesia (5.7%). SPL was 13.8 (12.5-15.0) cm immediately postoperative and 14.0 (13.0-15.0) at 1 month.

On-demand sildenafil has proved to be an effective PDE5i but with lower spontaneity scores compared to daily tadalafil treatment. We aimed to investigate the impact of on-demand sildenafil compared to bedtime use on efficacy and spontaneity scores in men with ED. We retrospectively analysed data from a cohort of men with mild/moderate ED treated for three months with on-demand sildenafil 50 mg oral suspension formulation (OSF) (group 1, n = 40), bedtime sildenafil 50 mg OSF (group 2, n = 40) and bedtime sildenafil 37.5 mg OSF (group 3, n = 40). After three months patients were evaluated with the International Index of Erectile Function-5 items (IIEF-5) and the Psychological and Interpersonal Relationship Scales-Short Form (PAIRS-SF) questionnaires. Propensity score matching was used to adjust for baseline confounders. The IIEF-5 and PAIRS-SF scores were compared between groups at follow-up with the repeated measures ANOVA test. Linear regression analyses tested the associations between study variables and spontaneity scores. After matching, median patient's age and ED duration were 56 (50-61) years and 18 (10-20) months, respectively. Compared to baseline, IIEF-5 scores significantly improved after sildenafil OSF treatment, irrespective of the therapeutic approach (all p < 0.01 vs. baseline). The PAIRS-SF spontaneity score was significantly better in group 2 [15 (13-16), p < 0.01] and group 3 [14 (14-16), p < 0.01] compared to the on-demand use [13 (12-13)]. Fewer time concerns were reported for bedtime use than on-demand sildenafil. Sildenafil OSF bedtime use was found to be an independent predictor for better spontaneity and fewer time concerns scores (all p < 0.001).

Sensation is a critical outcome in postoperative quality of life, impacting placement of erectile devices, sexual function, and overall well-being. Despite this, there is currently a lack of consensus on strategies to optimize sensation in phalloplasty. A comprehensive search of Medline and Embase databases was conducted with keywords related to phallic sensation in penile reconstruction. 237 abstracts were identified, and 28 articles, with 178 patients, met inclusion for final analysis. Studies consistently demonstrate improved sensation with neurorrhaphy; however, significant heterogeneity exists in the reported number of nerve coaptations and coaptation techniques as well as donor and recipient nerve selection. Reported sensory outcomes are mostly limited to presence or absence of sensation (tactile and/or erogenous or unspecified) and/or orgasmic ability. The lack of granularity in reported outcomes makes it challenging to draw robust evidence-based conclusions regarding optimal surgical techniques for maximizing sensory outcomes. Additionally, there is minimal discussion of approaches beyond solely performing nerve coaptations. Based on literature review, histomorphometric data, and our experience in phalloplasty and peripheral nerve surgery, we present a comprehensive approach to optimizing sensory outcomes in phalloplasty based on four key factors: nerve topography, selecting optimal nerve coaptations, considering the impact of sensory end-organ receptors, and integration of sensory re-education protocols targeting cortical plasticity and sexual rehabilitation.</p>","PeriodicalId":14068,"journal":{"name":"International Journal of Impotence Research","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143425289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
