Penile prosthesis (PP) is the mainstay of treatment in Peyronie's disease (PD) with co-existent refractory erectile dysfunction (ED). This study aimed to assess the clinical outcomes of patients who underwent PP as the first-line surgical treatment in PD without ED. A total of 636 patients underwent PP for PD from 2012 to 2022, but only 168 patients who underwent PP as first-line surgical management for PD with or without ED were included in the study. The mean (SD) age of 168 patients was 56.3 years (12.4). The mean curvature of the "PD with ED" group and the "PD without ED" group were 38.2 (5.6) degrees and 42.2 (5.9) degrees. The median (IQR) follow-up was 56.0 months (34.5- 61.4). Most (86.9%) patients underwent 3-piece inflatable PP. An important finding is that 33 patients (19.6%) without ED had undergone PP. Mechanical failure requiring revision surgery was less common in the 'without ED' group than in the ED group (6.8% vs. 10.2%, p 0.04). Most PD patients without ED (87.9%, 29/33) and with ED (88.9%, 120/135) were "satisfied" after PP implantation at six months, as defined by a score of ≥4 on a 5-point Likert scale. If surgery is offered in PD, PP may be considered a safe and effective first-line surgical treatment regardless of the ED, given the acceptable complications and high satisfaction rates. However, this new concept warrants further research., (© 2024. The Author(s), under exclusive licence to Springer Nature Limited.)

The significant discontinuation rate of available therapies and the paucity of curative options promoted the research on potential novel treatments suitable for erectile dysfunction patients. The aim of this study was to provide a summary of available evidence regarding the news and future perspectives related to the non-surgical treatment of erectile dysfunction. A narrative review of the literature was performed. A comprehensive search in the MEDLINE, Embase, and Scopus databases was done. Papers in English-language, published until April 2022, were included. No chronological restriction was applied. Retrospective and prospective clinical studies, as well as meta-analyses, were considered. Oro-dispersible formulations of phosphodiesterase type 5 inhibitors are particularly indicated in patients who have difficulty in swallowing solid dosage form; in addition, they constitute a discrete route of administration not requiring water. Low-intensity extracorporeal shock wave therapy is indicated in mild vasculogenic erectile dysfunction and in patients with vasculogenic erectile dysfunction poorly responsive to phosphodiesterase type 5 inhibitors. Stem cell therapy, platelet-rich plasma injections, and gene therapy seem promising regenerative treatments for selected patients with erectile dysfunction. Novel oral formulations of drugs commonly used in erectile dysfunction patients have recently become part of standard clinical practice. Regenerative treatments have been emerging in recent years and could become routine curative options in the near future. Further well-designed randomized controlled trials are needed to provide conclusive evidence on this topic and guide appropriate recommendations., (© 2022.

The Peyronie's Disease Questionnaire (PDQ) is a 15-question self-reported questionnaire that evaluates the severity and physical and psychosexual issues of Peyronie's disease (PD) symptoms in three scales: "psychological and physical symptoms," "penile pain," and "symptom bother." Previous studies validated the PDQ US version and confirmed its test-retest reliability and responsiveness. The aim is to translate and validate the Spanish version of the PDQ to be used in the clinical practice and in PD research studies in Spain. A non-interventional, observational study with 160 PD patients was conducted. Patients included from four healthcare centers in Spain and completed the PDQ in two study visits separated for a period of 4-7 days from March 2018 to June 2019. Patients received no type of treatment or intervention. Different statistical tests were applied to the data in order to validate the structural and construct of the PDQ, as well as its internal reliability, temporal stability reliability, reliability between observers, and test-retest reliability. Cronbach's alpha over 0.9 showed good internal consistency. We found an ICC agreement of 0.82 (test-retest) for the three scales of the Spanish version of the PDQ, which demonstrates good reliability. When comparing Visit 1 and Visit 2 questionnaires mean scores, the PDQ showed non-significant differences, as expected because no intervention or treatment was administered to the patients between visits. Translation and validation of the PDQ for the Spanish population makes available a valid, useful, and reliable tool to properly evaluate quality of life of men suffering PD., (© 2021.

Preputioplasty denotes various surgical techniques directed at resolving phimosis without the need for radical or partial circumcision. This narrative review summarizes the best-known surgical techniques of preputioplasty. A MEDLINE and EMBASE-based literature search of original manuscripts and case reports published in English has been carried out using the following key words: "circumcision", "partial circumcision", "phimosis", "paraphimosis", and "preputioplasty". Six different procedures are explored in more detail and illustrated. The complication rates of all surgical procedures presented here are reported to be low. In cases of medical (rather than cultural and religious) indications, foreskin-preserving procedures present useful alternatives to circumcision in the routine clinical practice of urologists and pediatric surgeons., (© 2021.

The present study aimed to describe and critically discuss the current evidence regarding the penile girth enhancement procedures for aesthetic purposes. We designed a narrative review of the literature. A comprehensive search in the MEDLINE database was performed. Original articles in English-language, published until March 2021, were selected. A total of 29 studies were included (3 reporting non-invasive approaches, 11 injection therapies, and 15 surgical procedures). The vast majority of articles (26, 89.7%) were not randomized controlled trials, with overall low quality and limited level of evidence. Only 1 (33.3%) paper regarding non-invasive approaches reported a minimal (+0.03 cm) but a significant increase of penile girth (p = 0.034). A low rate (11.2-14.4%) of mild, temporary adverse events and poor-to-moderate patient satisfaction were found. Eight (72.7%) articles concerning injection therapies showed a significant increase in penile girth (p < 0.05). A low rate of mild complications, generally at the injection site, and a high patient satisfaction rate (75-100%) were highlighted. Nine (60%) papers on surgical treatments found a significant increase in penile girth (p < 0.05), while the other 6 (40%) studies reported a generic improvement in penile circumference. Skin necrosis or ulcers, wound infections, or need for reoperation were reported in 8 (53.3%) studies. A high patient satisfaction rate (60-100%) was reported. Our review highlighted the overall positive results of injection procedures, the poor outcomes associated with non-invasive techniques, and the good efficacy and satisfaction with a non-negligible risk of complications in patients undergoing surgical treatments. However, the adverse events are probably largely under-reported and these procedures should still be considered under investigation due to the limited evidence available and the lack of guidelines., (© 2021.

The aim of this review is to describe reported techniques and to provide available scientific data on the success of penis length procedures for cosmetic purposes. Penis lengthening methods remain a controversial issue. Penis size is a matter of great interest among men who are affected by 'small penis anxiety'' or just believe themselves to have a small penis, even though the dimensions of the organ fall within the normal range. We performed a narrative review of the literature based on a comprehensive search in the MEDLINE database for original articles published until March 2021, referring to lengthening approaches exclusively for aesthetical reasons. Abstracts, opinion papers and case series ≤10 patients were not considered. We included the results of 14 papers in the review that gathered the experience obtained in a total of 1661 patients. Four of the studies referred to non-surgical procedures for penile length augmentation (PLA) and the remaining 10 analyzed the results of invasive (surgical) procedures. Both invasive and non-invasive techniques achieve similar improvements in penis length. These procedures vary in complexity and require specialized training and experience. However, the low scientific quality of the analyzed papers makes it difficult to establish recommendations to choose one technique over any other. However, it seems reasonable that, if possible, non-invasive techniques should be proposed as a first-line treatment. Before deciding the procedure, we must carry out a correct psychological evaluation of our patients, discuss with them the technique of choice, and adjust their expectations., (© 2021.

The aim of this paper is to analyze our experience with intraplaque administration of collagenase from Clostridium Histolyticum (CCH) together with penile modeling for selected patients with Peyronie's disease (PD). We conducted a prospective, multicenter, single-arm study. Patients were included from October 2015 to August 2019. We carried out the I + E PROTOCOL (IMPRESS + extender). Each cycle involved administration of two injections of CCH separated 24-72 h, up to a maximum of four cycles. 24-48 h after injection patients underwent penile modeling maneuvers with the use of a PTD at home for at least 4 h a day. After each cycle, penile curvature was evaluated by the Kelami test. Mean pretreatment curvature was 57° (30-100). Eighty-seven patients underwent at least a single cycle and were eligible for analysis. Mean number of cycles administered was 2. Final average curvature after treatment, regardless of the number of cycles was 34°, with a mean reduction in curvature of -23.29° (-41%). Across the first three cycles we found statistically significant differences in the means in terms of the degrees of curvature after each cycle (p < 0.05), however this was not maintained in the fourth cycle. Statistical significance was also found when comparing the initial and final curvature after the complete treatment. We can conclude that treatment with CCH for PD is safe and effective. The concomitant use of CCH and PTT may limit the number of treatment cycles necessary to optimize outcomes when compared with CCH alone.

In the present study we aimed to investigate the surgical outcomes of patients with persistent penile curvature (PC) after Collagenase Clostridium histolyticum (CCH) intraplaque injections. Data from 90 patients with persistent PC after CCH in a multicentre study from 6 andrological centres were retrospectively reviewed. Three standardized surgical techniques were performed. Group 1: plaque incision grafting (PIG) with penile prosthesis implant (PPI); Group 2: PIG without PPI; Group 3: Nesbit technique. Hospital stay, operative time, postoperative complications and PC persistency/recurrence (> 20°) were evaluated. Overall satisfaction and functional outcomes were assessed through International Index of Erectile Function-Erectile Function (IIEF-EF), Peyronie's Disease Questionnaire (PDQ), Female Sexual Function Index (FSFI) administered pre and 3 months postoperatively. Of all, 25 (27.8%) patients received grafting procedure + PPI (Group 1), 18 (20.0%) patients belonged to Group 2, and 47 (52.2%) to Group 3. Bovine pericardium graft and collagen fleece have been used in in 22 (51.2%) and 21 (48.8%) patients, respectively. Median penile length after surgery was 13.0 cm (IQR 12.0-15.0). After surgery, Group 1 showed higher increase in penile length after surgery and better improvements in terms of PDQ-PS. In contrast, both IIEF-EF and FSFI scores did not differ among groups. Overall, 86 (95.6%) did not report any complication. 4 (4.4%) patients had PC recurrence; of those, 2 (8.0%), 1 (5.6%) and 1 (2.1%) cases were observed in Group 1, Group 2 and Group 3, respectively. In case of persistent PC after CCH, surgical correction by grafting with or without concomitant PPI or Nesbit technique emerged as a technically feasible, effective and safe procedure, with no significant postoperative complications.

To date, surgical correction remains the gold standard for patients with stable Peyronie's disease (PD) due to its high efficacy and low morbidity. Among the surgical procedures, penile plication (PP) can be offered to men who have adequate erectile function and penile length (>13 cm), with a curvature <60° and a predicted shortening of maximum 20% of the penis. The aim of this paper is to review the new developments that have emerged in the last years about the use of PP in patients with PD. A nonsystematic review of the literature was carried out searching in the PubMed and EMBASE databases from January 01, 2009 to April 01, 2019 including the words 'Peyronie', 'penile curvature', 'penile induration', 'plication', and 'plicature'. New developments in PP in the last 10 years include avoiding degloving by using a penoscrotal incision, a new mathematical model to predict loss of length after PP, a wider range of indications including patients with severe (≥60°) or complex curvatures, burying knots to avoid later discomfort, and thinning or incising the plaque to prevent excessive shortening. PP is a well-founded procedure with great results in appropriately selected patients. Given the lack of any prospective randomized trial, no clear recommendation can be made of one technique over another.
