Meta-Analysis
INTRODUCTION
Peyronie's disease (PD) is a common penile disorder characterized by the formation of fibrous noncompliant hard nodules in the tunica albuginea of the penis. Collagenase Clostridium histolyticum (CCH) is an injectable drug that treats PD by enzymatically degrading plaque interstitial collagen. CCH has been used in patients with varying curvature, as well as in the acute and stable phases of the disease, through a variety of treatment regimens and combinations. We carried out a systematic review and meta-analysis to assess the efficacy of CCH combination therapies for PD.
METHODS
We selected 4 observational comparative studies and 3 randomized controlled trials including 532 participants from the PubMed, Embase, and Cochrane databases (until December 2023) to evaluate the efficacy of CCH combination therapies for PD. The primary outcome was clinical efficacy as evaluated by improvement in penile curvature and penile length, as well as by scores on the Peyronie's Disease Questionnaire (PDQ) for symptom bother, penile pain, and psychological symptoms. Continuous data were represented by mean difference (MD) and 95% CI. All data were analyzed by Review Manager version 5.3.
RESULTS
For penile length (MD, 0.81 cm; 95% CI, 0.17-1.45; P = .01), PDQ symptom bother (MD, -1.02; 95% CI, -1.83 to -0.21; P = .01), and PDQ penile pain (MD, -0.93; 95% CI, -1.50 to -0.36; P = .001), CCH combination therapy showed significantly greater improvements vs CCH monotherapy. However, in the other indicators, penile curvature and PDQ psychological symptoms, there was no significant difference between the therapies.
CONCLUSION
This meta-analysis supports that CCH combination therapies can partially increase penile length and ameliorate symptom bother and penile pain to some extent. However, CCH combination therapies still need to be evaluated through more high-quality research.

Review
INTRODUCTION
Peyronie's disease (PD) can have an immense psychological impact, with depression being a reported possible, severe consequence. To date, no literature reviews have systematically and critically assessed the relationship between PD and depression.
OBJECTIVES
The study sought to identify and critically appraise the current literature on the association between PD and depression.
METHODS
Studies had to address men with PD or probable PD and assess depression or depressive symptoms. Quantitative and qualitative, peer-reviewed, primary, empirical studies written in English or Danish were included. According to the guidelines for scoping reviews and the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews) guideline, we performed a systematic review of PubMed, PsycINFO, Embase, CINAHL, the Cochrane Library, and Web of Science. Reference lists of included studies were screened for additional sources. Gray literature was searched for in Google Scholar and Bielefeld Academic Search Engine. Data were charted using a data extraction form, and critical appraisal was performed using the QuADS (quality assessment with diverse studies) tool.
RESULTS
Thirteen studies were included. Most studies had a cross-sectional design, and also cohort studies and longitudinal observational studies without a control group were found. Depression was assessed mainly by validated questionnaires or diagnostic codes. Questionnaire studies found a prevalences of moderate to severe depression of 24% to 48%, while studies using diagnostic codes found depression in 4% to 37% of men with PD. The quality of the included studies varied from 38% to 82% of the maximum possible score in the QuADS assessment.
CONCLUSION
While most studies describe an association between PD and depression, the evidence is not comprehensive. The current literature is especially at risk of selection bias and the influence of confounding factors, and a direct causality between PD and depression cannot be established. Future research calls for more methodically rigorous studies as well as qualitative studies to understand the relationship.

Review
Priapism is defined as a persistent penile erection lasting more than 4 h. We searched the literature for reviews, case reports, and series for patients with lymphoproliferative disorders who developed priapism. The search involved all the lymphoproliferative disorders included in the revised 2016 World Health Organization classification of lymphoid neoplasms including chronic lymphocytic leukemia, multiple myeloma, Waldenström macroglobulinemia, and lymphomas. A total of 16 articles were found. The search included cases up to 4 January 2021. Priapism was seen most commonly as the first manifestation of lymphoproliferative disorders, rarely seen after treatment or after diagnosis.

Review
OBJECTIVE
Aphallia is a rare penile congenital abnormality. The aim of this systematic review was to assess all available literature on neophalloplasty in infancy with an interest in technical alternatives and clinical outcome.
MATERIALS AND METHODS
We performed a Pubmed search using the terms: neophalloplasty, neophallus, and phalloplasty, and selected articles that presented technical alternatives for penile construction in cases of penile dysgenesis, especially aphallia in children and/or adolescents.
RESULTS
A total of 319 articles were identified in the initial search. Among the different techniques presented in 19 papers collected, we categorized reconstructive procedures into two groups: microsurgical and non-microsurgical techniques. Among the microsurgical techniques, procedures such as the osteocutaneous fibular flap (n = 18), the myocutaneous latissimus dorsi flap (n = 24), and the radial forearm free flap (n = 293) were reported. Among the non-microsurgical techniques, we found a wider range of technical options (6 in total). Most were based on groin, abdominal, and scrotal flaps. Long-term reports on the functionability of the neophallus and psychological aspects of the patients are lacking.
CONCLUSION
In assessing recent literature, it seems rational that neophalloplasty should be regarded as the preferred strategy for boys born with aphallia, in opposition to female gender assignment.

INTRODUCTION
Penile prosthesis implantation (PPI), performed with or without adjunct straightening techniques, is one of the available surgical options in cases of Peyronie's disease (PD) with concomitant erectile dysfunction (ED). The aim of the study was to systematically identify and evaluate evidence regarding IPP in patients with PD and ED.
EVIDENCE ACQUISITION
Using Cochrane's methodological recommendations on systematic reviews, we conducted a systematic review of the literature on clinical research regarding the use of PPI, alone or in combination with any straightening maneuvers in the treatment of patients with PD and ED. The search was carried until January 2020. We included studies in English language with primary population patients with PD and ED who underwent IPP with the intent to treat the PD. All studies that were not original clinical research articles, reported insufficient data or included fewer than 5 patients were excluded from the final analysis.
EVIDENCE SYNTHESIS
In total 43 clinical articles with more than 2000 patients (N.=2143) investigating the effects of penile prosthesis implantation (PPI) for the treatment of PD with or without ED were included in the study. Depending on the severity of the penile curvature, additional penile deformities (i.e. hourglass deformity), penile length, prior operations and surgeons experience, 6 main categories of surgical techniques of PPI for penile straightening and treatment of PD were identified: PPI only, PPI with modelling of the penis, PPI with plication of the penis on the convex side of the curvature, PPI with plaque incision(s), PPI with plaque incision/excision plus grafting and PPI with grafting and penile lengthening.
CONCLUSIONS
Overall, patients with PD and ED can expect excellent outcomes with PPI against a minimal risk of side effects. No definite conclusions can be made regarding which technique is superior.

Meta-Analysis Review
CONTEXT
In patients with Peyronie's disease (PD), oral, injected, or topical agents provide limited efficacy. In this setting, combination of two or more conservative treatments may improve symptoms further.
OBJECTIVE
To explore the effects of available conservative combination therapies for active and stable PD through a systematic review and meta-analysis.
EVIDENCE ACQUISITION
We searched multiple databases and sources of gray literature until June 2021. We included randomized or observational comparative studies assessing any conservative combination therapies for PD. We undertook a random-effect meta-analysis when at least two studies employed the same treatment modality (PROSPERO: CRD42021224517).
EVIDENCE SYNTHESIS
Overall, 13 studies on active PD and ten on stable PD (1962 participants) were included. Most included studies raised methodological concerns. In patients with active or stable PD, the available evidence is inconclusive to support the use of any combination treatment modality, such as intralesional verapamil injections, antioxidants, and other oral, injected, or topical agents. Based on data availability, we performed a meta-analysis to compare the effect of collagenase Clostridium histolyticum (CCH) plus adjunctive mechanical therapies (penile traction or vacuum pump) versus CCH monotherapy on penile curvature and length in patients with stable PD. CCH and adjunctive mechanical therapies resulted in an additional decrease of 0.3° in penile curvature (95% confidence interval [CI]: -3.97 to 4.49, I = 0%) and in an increase of 0.5 cm in penile length (95% CI: -0.32 to 1.4, I = 70%) compared with CCH monotherapy.
CONCLUSIONS
The available combination treatment modalities, including the addition of adjunctive mechanical therapies to CCH, do not improve symptoms further compared with monotherapy and should not be implemented in patients with active or stable PD. Further high-quality randomized trials combining only recommended treatments are mandatory.
PATIENT SUMMARY
Despite the interest in and optimism for combination treatment modalities, the road to an effective conservative therapy for Peyronie's disease still seems long.

Meta-Analysis Review
BACKGROUND
Previous studies have suggested a protective effect of male circumcision on human papillomavirus (HPV) infections in males, and that this protection may be conferred to their female sexual partners.
OBJECTIVES
To synthesize the available evidence on the association between male circumcision and HPV infections in males and females.
DATA SOURCES
We searched MEDLINE, Embase, Scopus, Cochrane, LILACS, and ProQuest Dissertations & Theses Global for records published up to 22 June 2022.
STUDY ELIGIBILITY
We considered observational and experimental studies that assessed male circumcision status and HPV prevalence, incidence, or clearance in males or females for inclusion.
PARTICIPANTS
Males and their female sexual partners who were tested for genital HPV infection.
INTERVENTIONS
Male circumcision compared with no circumcision.
THE RISK-OF-BIAS ASSESSMENT
The Newcastle-Ottawa scale was used for observational studies, and the Cochrane risk-of-bias tool was used for randomized trials.
DATA SYNTHESIS
We estimated summary measures of effect and 95% CIs for the prevalence, incidence, and clearance of HPV infections in males and females using random-effects meta-analysis. We assessed the effect modification of circumcision on HPV prevalence by the penile site in males using random-effects meta-regression.
RESULTS
Across 32 studies, male circumcision was associated with decreased odds of prevalent HPV infections (odds ratio, 0.45; 95% CI, 0.34-0.61), a reduced incidence rate of HPV infections (incidence rate ratio, 0.69; 95% CI, 0.57-0.83), and an increased risk of clearing HPV infections (risk ratio, 1.44; 95% CI, 1.28-1.61) at the glans penis among male subjects. Circumcision conferred greater protection against infection at the glans than the shaft (odds ratio, 0.68; 95% CI, 0.48-0.98). Females with circumcised partners were protected from all outcomes.
CONCLUSIONS
Male circumcision may protect against various HPV infection outcomes, suggesting its prophylactic potential. Understanding the site-specific effects of circumcision on HPV infection prevalence has important implications for studies of HPV transmission.

Review
CONTEXT
Ductal adenocarcinoma (DAC) is relatively rare, but is nonetheless the second most common subtype of prostate cancer. First described in 1967, opinion is still divided regarding its biology, prognosis, and outcome.
OBJECTIVES
To systematically interrogate the literature to clarify the epidemiology, diagnosis, management, progression, and survival statistics of DAC.
MATERIALS AND METHODS
We conducted a literature search of five medical databases from inception to May 04 2020 according to PRISMA criteria using search terms "prostate ductal adenocarcinoma" OR "endometriod adenocarcinoma of prostate" and variations of each.
RESULTS
Some 114 studies were eligible for inclusion, presenting 2 907 170 prostate cancer cases, of which 5911 were DAC. [Correction added on 16 January 2021 after the first online publication: the preceding statement has been corrected in this current version.] DAC accounts for 0.17% of prostate cancer on meta-analysis (range 0.0837%-13.4%). The majority of DAC cases were admixed with predominant acinar adenocarcinoma (AAC). Median Prostate Specific Antigen at diagnosis ranged from 4.2 to 9.6 ng/mL in the case series.DAC was more likely to present as T3 (RR1.71; 95%CI 1.53-1.91) and T4 (RR7.56; 95%CI 5.19-11.01) stages, with far higher likelihood of metastatic disease (RR4.62; 95%CI 3.84-5.56; all -values < .0001), compared to AAC. Common first treatments included surgery (radical prostatectomy (RP) or cystoprostatectomy for select cases) or radiotherapy (RT) for localized disease, and hormonal or chemo-therapy for metastatic disease. Few studies compared RP and RT modalities, and those that did present mixed findings, although cancer-specific survival rates seem worse after RP.Biochemical recurrence rates were increased with DAC compared to AAC. Additionally, DAC metastasized to unusual sites, including penile and peritoneal metastases. Where compared, all studies reported worse survival for DAC compared to AAC.
CONCLUSION
When drawing conclusions about DAC it is important to note the heterogenous nature of the data. DAC is often diagnosed incidentally post-treatment, perhaps due to lack of a single, universally applied histopathological definition. As such, DAC is likely underreported in clinical practice and the literature. Poorer prognosis and outcomes for DAC compared to AAC merit further research into genetic composition, evolution, diagnosis, and treatment of this surprisingly common prostate cancer sub-type.
PATIENT SUMMARY
Ductal prostate cancer is a rare but important form of prostate cancer. This review demonstrates that it tends to be more serious at detection and more likely to spread to unusual parts of the body. Overall survival is worse with this type of prostate cancer and urologists need to be aware of the presence of ductal prostate cancer to alter management decisions and follow-up.

Review
INTRODUCTION
Knowledge of the normal size of the urethral meatus in boys is important for safely performing urethral catheterization and fundamental to the diagnosis and treatment of paediatric urological conditions. However, clinicians often rely subjectively on previous experience and clinical judgement, rather than a robust evidence-base. A systematic review of the literature was undertaken to define the calibre of the male urethral meatus in paediatric age-groups.
METHODS
The MEDLINE and EMBASE databases were systematically searched from inception to December 2020 for studies measuring meatal calibre in boys up to 16 years of age. Google Scholar searches along with forward and backward citation tracking identified additional studies. Studies of subjects >16 years, females, or patients with urethral diseases were excluded.
RESULTS
Nine articles (2084 paediatric subjects) were included in the final review. Mean meatal calibre increases non-linearly with age, with accelerated growth occurring during infancy (mini-puberty) and adolescence (puberty). Meatal calibre can be approximately grouped by age as follows: neonate (6-10Fr); infant (10-12Fr); child (12-14Fr); and adolescent (14-18Fr). There is substantial individual variability for same-aged children. Meatal calibre has been independently related to height, weight, and penile size, but the effects of ethnicity and circumcision remain unclear.
CONCLUSIONS
The evidence-base for this fundamental aspect of paediatric urology includes only a few low-quality studies and is largely derived from one early study of circumcised American boys. Further studies are warranted to establish normative urethral size values based on rigorous, contemporary data with known dependent variables also included.

Review
BACKGROUND
There is currently a paucity of data on urethral-related outcomes in metoidioplasty and phalloplasty gender affirming surgery (MaPGAS) with urethral lengthening (UL)and vaginectomy.
METHODS
A systematic review was performed utilizing MEDLINE, Web of Science, Cochrane Library, Europe PMC, OSF Preprints, and EMBASE. Methodologic quality was scored using Methodological Index for Non-Randomized Studies (MINORS) criteria. Four independent reviewers performed the article evaluation, data extraction, and methodologic quality assessment. Primary outcomes included standing to urinate/pee (STP), penile length, glanular meatus, urethral stricture, fistula, and flap necrosis. Results were summarized qualitatively with descriptive statistics.
RESULTS
A total of 2,881 articles of which 11 retrospective reviews of 13 cohorts met criteria; 4.3/16 average (avg) MINORS score. Six metoidioplasty cohorts had an average penile length of 6 cm, 74% reported successful STP, and a quarter developed stricture or fistula. Phalloplasty cohorts included radial forearm flap (RF) and Anterolateral Thigh flap (ALT). Of the 4 RF studies nearly a third developed a stricture or fistula and only one study reported 99% STP with a glanular meatus. Three ALT studies reported no length but had 80-90% STP with a glanular meatus and a quarter with stricture or fistula.
CONCLUSIONS
Urethral complications in MaPGAS-UL in a cohort with prior vaginectomy are common and variably reported. Patient centered outcome measures as well as clearly defined outcome metrics created in partnership with community members are needed.
