Meta-Analysis
BACKGROUND
Premature ejaculation is a common sexual dysfunction disease in adult males. There are many clinical trials shown that dorsal penile nerve block can prolong the ejaculation latency to a certain extent in the vagina. In this study, we aim to use a meta-analysis to evaluate the efficacy and safety of dorsal penile nerve block for premature ejaculation.
METHODS AND ANALYSIS
We will search for PubMed, Cochrane Library, AMED, EMbase, WorldSciNet, Nature, Science online and China Journal Full-text Database (CNKI), China Biomedical Literature CD-ROM Database (CBM), and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to February 2019. The quality of the included RCTs will be evaluated with the risk of bias (ROB) tool and evidence will be evaluated by GRADE. Data analysis will be used the special software like RevMan (version 5.3) and EndNote X7.
RESULTS
The results of this meta-analysis will be submitted to a peer-reviewed journal for publication.
ETHICS AND DISSEMINATION
This systematic review will evaluate the efficacy and safety of dorsal penile nerve block for premature ejaculation. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process Trial.

BACKGROUND
Human papilloma virus (HPV) associated cervical cancer remains a global concern particular, in Sub-Saharan Africa (SSA) where the impact is felt most. Evidence show that many other cancers such as vaginal, anal, oropharyngeal, penile are because of persistent infection with HPV especially, high-risk types.
AIM
We mapped evidence on the incidence, prevalence, mortality, and the trends of human papillomavirus-related cancers in SSA.
METHODS
A comprehensive literature search was conducted from several databases including PubMed, Google scholar, Science Direct, and CINAHL and MEDLINE via EBSCOhost as well as World Health Organization website for grey literature. Studies reporting HPV-related cancers in SSA outcomes including prevalence, incidence, mortality, and trends were included in this study. The risk of bias of the included studies were assessed using the mixed methods appraisal tool version 2011. We employed PRISMA (preferred reporting items for systematic reviews and meta-analyses) to report the search results. Thematic analysis used to reveal the emerging themes from the included studies.
RESULTS
Seventy-four (74) studies were retrieved at full article screening, eight of them (six reviews, and two quantitative study) were eligible for data extraction. The degree of agreement between the two independent reviewers following full article screening, was 86.49% agreement versus 64.57% likely by chance which constituted moderate to significant agreement (Kappa statistic = 0.62, p-value< 0.05). Of the eight included studies, four (50%) studies generalized about SSA with no country of interest; two (25%) studies were conducted in Nigeria; one (12.5%) reported about Uganda, Zambia, Guinea, Malawi Tanzania, Mali, Mozambique, Zimbabwe; and one (12.5%) reported about Ethiopia, Senegal, Zimbabwe and Uganda. These eight included studies reported evidence on more than one outcome of interest. Four studies reported about the prevalence of HPV-related cancers, seven studies reported about the incidence, four studies reported about mortality, and four studies reported about the trends of HPV-related cancers.
CONCLUSION
This study observation highlighted a gap of knowledge regarding the epidemiological data on the recent HPV prevalence in SSA, which will have a potential impact in determining the distribution of HPV on different body sites (cervix, penis, vagina, vulva, anus and oropharynx). Ongoing research projects are recommended in SSA to enhance the value of HPV, and HPV-associated cancers epidemiological data to inform strategies or/and policies on prevention, diagnosis, and treatment of HPV-related conditions.

Comparative Study Meta-Analysis
Comparison of clinical feasibility and oncological outcomes between video endoscopic and open inguinal lymphadenectomy for penile cancer: A systematic review and meta-analysis.
BACKGROUND
To compare the clinical feasibility and oncological outcomes of video endoscopic inguinal lymph node dissection (VE-ILND) and open inguinal lymph node dissection (O-ILND) in the management of penile cancer.
METHODS
We searched published articles in the PubMed, Embase, Cochrane Library, Web of science, China National Knowledge Infrastructure, and Wanfang databases. Data were extracted by 2 independent authors, and meta-analysis was performed by using Review Manager software version 5.3.
RESULTS
Ten studies were included. Compared with the O-ILND group, the VE-ILND group exhibited less intraoperative blood loss (standardized mean difference [SMD] = 3.12; 95% confidence intervals [95% CIs] [1.27, 4.98]; P = .001), shorter hospital stay (SMD = 1.77; 95% CIs [0.94, 2.60]; P < .001), shorter drainage time (SMD = 2.69; 95% CI [1.47, 3.91]; P < .001), reduced wound infection rate (odds ratio [OR] = 10.62; 95% CI [4.01, 28.10]; P < .001); reduced skin necrosis rate (OR = 7.48; 95% CI [2.79, 20.05]; P < .001), lower lymphedema rate (OR = 3.23; 95% CI [1.51, 6.88]; P = .002), equivalent lymphocele rate (OR = 0.83; 95% CI [0.31, 2.23]; P = .720), and parallel recurrence rate (OR = 1.54; 95% CI [0.41, 5.84]; P = 0.530). However, the number of dissected lymph nodes (OR = 0.25; 95% CI [0.03, 0.47]; P = .030) was slightly increased in the O-ILND group. GRADE recommendations of primary outcomes were shown in a summary of findings table.
CONCLUSIONS
For perioperative outcomes, VE-ILND is superior to O-ILND. For short-term oncological outcomes, VE-ILND is comparable to O-ILND. However, long-term oncological control still requires further verification.

Meta-Analysis
Human papillomavirus (HPV) infection appears to play an important role in the development of penile cancer (PeCa), but their relationship remains unclear. Therefore, we performed a systematic review and meta-analysis to elucidate their relationship. We systematically searched Embase, PubMed, Cochrane Library, and Web of Science for case-control studies and cross-sectional studies using polymerase chain reaction (PCR) technology on formalin-fixed paraffin-embedded (FFPE) or paraffin-embedded (PE) PeCa tissues to detect HPV (published between January 1, 2007, and December 29, 2017; no language restrictions). Twenty-two studies were identified, and 1664 cases were available for analysis. The combined HPV infectious risk of PeCa is 51.0% (95% confidence interval [CI]: 43.0%-60.0%). The three most common subtypes of HPV were HPV16 (28.5%), HPV18 (2.3%), and HPV6 (2.3%). The virus was relevantly associated with basaloid (85.5%, 95% CI: 77.2%-93.8%) and warty (50.0%, 95% CI: 35.2%-64.8%) carcinomas. The invasiveness of PeCa was not associated with HPV (χ = 0.181, df = 1, P < 0.671). HPV infection in PeCa tended to be moderately differentiated (54.4%, 95% CI: 47.7%-61.1%). This study found that almost half of PeCa patients are associated with HPV. The most commonly associated genotype is HPV16, but several other genotypes were also detected. In addition to types 6 and 11, other single low-risk HPV infections have been found to contribute to PeCa to a lesser degree. HPV-positive tumors tend to exhibit warty and/or basaloid features, corresponding to a moderate histological grade. The role of HPV in PeCa should be revisited to provide evidence for the development of PeCa in the presence of HPV infection.

Review
INTRODUCTION
Women's choices for a sexual partner are influenced by numerous personal, cultural, social, political and religious factors, and may also include aspects of penile anatomy such as male circumcision (MC) status.
AIM
To perform a systematic review examining (i) whether MC status influences women's preference for sexual activity and the reasons for this, and (ii) whether women prefer MC for their sons.
METHODS
PRISMA-compliant searches were conducted of PubMed, Google Scholar, Embase, and the Cochrane Database of Systematic Reviews. Articles that met the inclusion criteria were rated for quality using the SIGN system.
RESULTS
Database searches identified 29 publications with original data for inclusion, including 22 for aim (i) and 4 of these and 7 others pertaining to aim (ii). In the overwhelming majority of studies, women expressed a preference for the circumcised penis. The main reasons given for this preference were better appearance, better hygiene, reduced risk of infection, and enhanced sexual activity, including vaginal intercourse, manual stimulation, and fellatio. In studies that assessed mothers' preference for MC of sons, health, disease prevention, and hygiene were cited as major reasons for this preference. Cultural differences in preference were evident among some of the studies examined. Nevertheless, a preference for a circumcised penis was seen in most populations regardless of the frequency of MC in the study setting.
CONCLUSION
Women's preferences generally favor the circumcised penis for sexual activity, hygiene, and lower risk of infection. The findings add to the already well-established health benefits favoring MC and provide important sociosexual information on an issue of widespread interest.

Meta-Analysis
BACKGROUND
Men who have sex with men (MSM) are disproportionately affected by HIV and other sexually transmitted infections (STIs) worldwide. Previous reviews investigating the role of circumcision in preventing HIV and other STIs among MSM were inconclusive. Many new studies have emerged in the past decade. To inform global prevention strategies for HIV and other STIs among MSM, we reviewed all available evidence on the associations between circumcision and HIV and other STIs among MSM.
METHODS
In this systematic review and meta-analysis, we searched PubMed, Web of Science, BioMed Central, Scopus, ResearchGate, Cochrane Library, Embase, PsycINFO, Google Scholar, and websites of international HIV and STI conferences for studies published before March 8, 2018. Interventional or observational studies containing original quantitative data describing associations between circumcision and incident or prevalent infection of HIV and other STIs among MSM were included. Studies were excluded if MSM could not be distinguished from men who have sex with women only. We calculated pooled odds ratios (ORs) and their 95% CIs using random-effect models. We assessed risk of bias using the Newcastle-Ottawa scale.
FINDINGS
We identified 62 observational studies including 119 248 MSM. Circumcision was associated with 23% reduced odds of HIV infection among MSM overall (OR 0·77, 95% CI 0·67-0·89; number of estimates [k]=45; heterogeneity I=77%). Circumcision was protective against HIV infection among MSM in countries of low and middle income (0·58, 0·41-0·83; k=23; I=77%) but not among MSM in high-income countries (0·99, 0·90-1·09; k=20; I=40%). Circumcision was associated with reduced odds of herpes simplex virus (HSV) infection among MSM overall (0·84, 0·75-0·95; k=5; I=0%) and penile human papillomavirus (HPV) infection among HIV-infected MSM (0·71, 0·51-0·99; k=3; I=0%).
INTERPRETATION
We found evidence that circumcision is likely to protect MSM from HIV infection, particularly in countries of low and middle income. Circumcision might also protect MSM from HSV and penile HPV infection. MSM should be included in campaigns promoting circumcision among men in countries of low and middle income. In view of the substantial proportion of MSM in countries of low and middle income who also have sex with women, well designed longitudinal studies differentiating MSM only and bisexual men are needed to clarify the effect of circumcision on male-to-male transmission of HIV and other STIs.

Meta-Analysis
BACKGROUND
High-risk human papilloma viruses (HPV) are a causative agent of anogenital and oropharyngeal cancers. Patients treated for a preinvasive or invasive HPV-associated cancer may be at increased risk of a second such malignancy.
METHODS
We performed a systematic review and random effects meta-analysis to estimate the risk of HPV-associated cancer after prior diagnosis. Studies reporting second cancers at anogenital and oropharyngeal sites after prior diagnoses (preinvasive/invasive HPV-associated cancer) were identified. Studies reporting standardised incidence ratios (SIRs) were included in formal meta-analyses of second cancer risk. (PROSPERO ID: CRD42016046974).
RESULTS
Searches returned 5599 titles, including 60 unique, eligible studies. Thirty-two (98 comparisons) presented SIRs for second cervical, anal, vulvo-vaginal, penile, and/or oropharyngeal cancers, included in the meta-analyses. All studies (and 95/98 comparisons) reported increased cancers in the population with previous HPV-associated cancer when compared to controls. Pooled SIRs for second primary cancers ranged from 1.75 (95% CI 0.66-4.67) for cervical cancer after primary anal cancer, to 13.69 (95% CI 8.56-21.89) for anal cancer after primary vulvo-vaginal cancer.
CONCLUSIONS
We have quantified the increased risk of second HPV-associated cancer following diagnosis and treatment for initial cancer or preinvasive disease. This has important implications for follow-up, screening, and future therapeutic trials.

BACKGROUND
Current optical diagnostic techniques for malignancies are limited in their diagnostic accuracy and lack the ability to further characterise disease, leading to the rapidly increasing development of novel imaging methods within urology. This systematic review critically appraises the literature for novel imagining modalities, in the detection and staging of urological cancer and assesses their effectiveness via their utility and accuracy.
METHODS
A systematic literature search utilising MEDLINE, EMBASE and Cochrane Library Database was conducted from 1970 to September 2018 by two independent reviewers. Studies were included if they assessed real-time imaging modalities not already approved in guidelines, in vivo and in humans. Outcome measures included diagnostic accuracy and utility parameters, including feasibility and cost.
RESULTS
Of 5475 articles identified from screening, a final 46 were included. Imaging modalities for bladder cancer included optical coherence tomography (OCT), confocal laser endomicroscopy, autofluorescence and spectroscopic techniques. OCT was the most widely investigated, with 12 studies demonstrating improvements in overall diagnostic accuracy (sensitivity 74.5-100% and specificity 60-98.5%). Upper urinary tract malignancy diagnosis was assessed using photodynamic diagnosis (PDD), narrow band imaging, optical coherence tomography and confocal laser endomicroscopy. Only PDD demonstrated consistent improvements in overall diagnostic accuracy in five trials (sensitivity 94-96% and specificity 96.6-100%). Limited evidence for optical coherence tomography in percutaneous renal biopsy was identified, with anecdotal evidence for any modality in penile cancer.
CONCLUSIONS
Evidence supporting the efficacy for identified novel imaging modalities remains limited at present. However, OCT for bladder cancer and PDD in upper tract malignancy demonstrate the best potential for improvement in overall diagnostic accuracy. OCT may additionally aid intraoperative decision making via real-time staging of disease. Both modalities require ongoing investigation through larger, well-conducted clinical trials to assess their diagnostic accuracy, use as an intraoperative staging aid and how to best utilise them within clinical practice.

Meta-Analysis
The significance of perineural invasion (PNI) present in penile cancer (PC) is controversial. In order to clarify the predictive role of PNI in the inguinal lymph node (ILN) metastases (ILNM) and oncologic outcome of patients, we performed this meta-analysis and systematic review. The search of PubMed, Embase, and Web of Science was conducted for appropriate studies, up to 20 January 2018. The pooled odds ratio (OR) and hazard ratio (HR) with their 95% confidence interval (CI) were applied to evaluate the difference in ILNM and oncologic outcome between patients present with PNI and those who were absent. A total of 298 in 1001 patients present with PNI were identified in current meta-analysis and systematic review. Significant difference was observed in ILNM between PNI present and absent from patients with PC (OR = 2.98, 95% CI = 2.00-4.45). Patients present with PNI had a worse cancer-specific survival (CSS) (HR = 3.58, 95% CI = 1.70-7.55) and a higher cancer-specific mortality (CSM) (HR = 2.20, 95% CI = 1.06-3.82) than those cases without PNI. This meta-analysis and systematic review demonstrated the predictive role of PNI in ILNM, CSS, and CSM for PC patients.

Meta-Analysis Review
Vacuum therapy has been widely used for penile rehabilitation after radical prostatectomy (RP), but its efficacy and safety are unclear. The study was to evaluate the efficacy and safety of the early use of vacuum therapy for post-RP men. Randomized clinical trials were selected according to predefined inclusion and exclusion criteria. RevMan 5.3 software was used for meta-analyses. In total, six randomized controlled trials were included with a total of 273 post-RP patients. The meta-analysis revealed that the early use of vacuum therapy could significantly improve the five-item International Index of Erectile Function and penile shrinkage in post-RP patients. Few adverse events were reported across the included studies. This review suggests that the early use of vacuum therapy appears to have excellent therapeutic effect on post-RP patients and no serious side effects were identified. Due to overall limited quality of the included studies, the therapeutic benefit of vacuum therapy in penile rehabilitation needs be substantiated to a limited degree in the future. Better methodological, large controlled trials are expected to verify the therapeutic effect of vacuum therapy in penile rehabilitation.
