Meta-Analysis
INTRODUCTION
Obesity is associated with a higher prevalence of various comorbidities including erectile dysfunction (ED). Bariatric surgery leads to weight loss and remission of weight-related diseases. The exact influence of bariatric treatment on ED is yet to be established; however, the number of papers on the subject is growing.
METHODOLOGY
A systematic review with meta-analysis comparing erectile dysfunction before and after surgery was conducted according to PRISMA guidelines with a literature search performed in June 2022. Inclusion criteria involved (1) ED assessment using the International International Index of Erectile Function (IIEF) and (2) longitudinal study design. Secondary endpoints involved hormonal changes and specific fields of IIEF.
RESULTS
An initial search yielded 878 records. Fourteen studies were included in the meta-analysis involving 508 patients. The quality of analyzed studies was moderate. Analysis showed significant differences in IIEF before and after surgery (Std. MD = 1.19, 95% CI 0.72 to 1.66, p<0.0001). Testosterone after surgery is higher by 156.32 pg/ml (95% CI 84.78 to 227.86, p<0.0001). There were differences in erectile function (MD:4.86, p < 0.0001), desire (MD: 1.21, p < 0.0001), intercourse satisfaction (MD: 2.16, p < 0.0001), and overall satisfaction (MD: 1.21, p = 0.003). There were no differences in terms of orgasms (MD: 0.65, p = 0.06).
CONCLUSION
There are differences in ED before and after bariatric surgery. Patients achieve 19% more in the IIEF questionnaire showing improvement. Further studies, including multivariate regression models on large cohorts, are required to determine whether the surgery is an independent factor in alleviating ED.

Meta-Analysis
The true HPV prevalence in the foreskins of infants and children has been little documented, but reporting on this prevalence is of great importance given its impact on the rationale for treating asymptomatic boys. We searched multiple databases from 1960 to 2016 for observational or prospective studies that reported on HPV prevalence in foreskins. We conducted a meta-analysis using a random-effects model to pool for HPV prevalence in the foreskins of infants and children. Eight studies, with a total of 556 infants and children with phimosis, were eligible for the meta-analysis. The pooled overall prevalence of general HPV, high-risk HPV, low-risk HPV, HPV 16/18, HPV 16, and HPV 18 were 17.3 (95%CI: 0.8-46.3), 12.1 (95% CI: 0.9-31.5), 2.4 (95% CI: 0.0-11.2), 4.8 (95% CI: 0.0-16.8), 1.7 (95% CI: 0.0-5.1), and 0 (95% CI: 0-0.5), respectively. The estimated HPV prevalence in foreskins was not zero among infants and children, which implies HPV transmission other than by sexual contact. Considering that high-risk HPV is detected in asymptomatic infants and children, future studies are warranted to determine whether preventive treatments in asymptomatic infants and children could be effective in preventing persistence or transmission of high-risk HPV.

Meta-Analysis
BACKGROUND
The findings of associations between prenatal air pollution exposure and hypospadias risk in offspring are inconsistent. No systematic review or meta-analysis has yet summarized the present knowledge on the aforementioned topic.
METHODS
Relevant manuscripts were identified by searching PubMed and Web of Science databases through January 31, 2020. Summary odds ratios (ORs) with 95% confidence intervals (CIs) in meta-analyses were estimated based on a random effects model. Publication bias was evaluated by funnel plots, Begg's test, and Egger's test.
RESULTS
The search identified 3,032 relevant studies. Sixteen studies cumulatively involving 21,701 hypospadias cases and 1,465,364 participants were included. All of these studies were classified as having a low risk of bias. We classified pollutants as nitrogen oxides, particulate matter (PM), ozone, and other exposures. The exposure window to pollutants varied from three months before conception to seven days after delivery. In the meta-analyses, only PM exposure in the first trimester was related to increased risk of hypospadias (per 10 μg/m OR = 1.34; 95% CI: 1.06-1.68).
CONCLUSION
We found evidence for an effect of PM exposure on hypospadias risk. Improvements in the areas of study design, exposure assessment, and specific exposure window are needed to advance this field.

OBJECTIVE
The aim of this study is to review the literature on the use of antifungal prophylaxis in penile prosthesis (PP) surgery and provide a summary on its efficacy as an adjunct to current prophylactic regimes in patients undergoing PP surgery.
MATERIALS AND METHODS
PubMed, Medline, and EMBASE databases were systematically searched up to May 2020. All included studies were analysed and the information extracted included author, title of study, year of publication, type of study, journal of publication, and main findings regarding post PP implantation fungal infections.
RESULTS
Nine relevant studies were included in this review, comprising retrospective single-centre studies and retrospective multicentre studies ranging from 2017 to 2020. Fungal infections were found responsible for 11.1% of all PP infections, with a greater risk in patients with diabetes, obesity, and from warmer climates. Current American Urological Association (AUA) and European Association of Urology (EAU) prophylaxis guidelines do not incorporate the use of antifungals. Trials of antifungal prophylaxis regimes combined with antibiotic prophylaxis have demonstrated a reduction in PP fungal infections.
CONCLUSIONS
Fungal infections represent a significant proportion of implant infections and therefore antifungal prophylaxis is warranted. Future studies comparing the efficacy of traditional antibiotic prophylaxis as set out by AUA/EAU with novel prophylaxis regimes including the addition of an antifungal may provide more definitive guidance on this issue. Until then antifungal prophylaxis in all patients undergoing PP procedures may provide a significant cost-effect benefit.

OBJECTIVES
Penile cancer is not very frequent. To control the disease oncologically, we must perform inguinal lymphadenectomy in cases of high-risk histology, poor prognosis and palpable lymph nodes. The open inguinal lymphadenectomy has a high rate of morbidity. Consequently, this systematic review intends to summarize the published literature regarding the oncologic and post-surgery outcomes in video-endoscopic inguinal lymphadenectomy (VEIL).
METHODS
A literature search has conducted through Pubmed, EMBASE and Cochrane library for English and Spanish articles.
RESULTS
Our literature search identified 12 articles. In total, 161 patients have been subjected to 226 VEIL. Their average age was 55.66 years. In the case of open inguinal lymphadenectomy, 90 patients have been subjected to 106 operations. The rate of cutaneous complications was 6% for VEIL and 55.6% for open lymphadenectomy. The rate of lymphatic complications was very similar in both types of lymphadenectomy. The average number of lymph nodes obtained was 9.12 for VEIL and 7.02 lymph nodes for the open approach.
CONCLUSION
Video-endoscopic inguinal lymphadenectomy contributes to less morbidity with a lower- rate of cutaneous complications and less severity. Furthermore, VEIL gives lower hospital stay without changing in initial oncologic outcomes. Although we need longer series to stablish the oncologic long-term results.

Meta-Analysis
BACKGROUND
Robotic-assisted laparoscopic prostatectomy (RALP) is widely used to surgically treat clinically localized prostate cancer. It is typically performed using an approach (standard RALP) that mimics open retropubic prostatectomy by dissecting the so-called space of Retzius anterior to the bladder. An alternative, Retzius-sparing (or posterior approach) RALP (RS-RALP) has been described, which is reported to have better continence outcomes but may be associated with a higher risk of incomplete resection and positive surgical margins (PSM).
OBJECTIVES
To assess the effects of RS-RALP compared to standard RALP for the treatment of clinically localized prostate cancer.
SEARCH METHODS
We performed a comprehensive search of the Cochrane Library, MEDLINE, Embase, three other databases, trials registries, other sources of the grey literature, and conference proceedings, up to June 2020. We applied no restrictions on publication language or status.
SELECTION CRITERIA
We included trials where participants were randomized to RS-RALP or standard RALP for clinically localized prostate cancer.
DATA COLLECTION AND ANALYSIS
Two review authors independently classified and abstracted data from the included studies. Primary outcomes were: urinary continence recovery within one week after catheter removal, at three months after surgery, and serious adverse events. Secondary outcomes were: urinary continence recovery six and 12 months after surgery, potency recovery 12 months after surgery, positive surgical margins (PSM), biochemical recurrence-free survival (BCRFS), and urinary and sexual function quality of life. We performed statistical analyses using a random-effects model. We rated the certainty of evidence using the GRADE approach.
MAIN RESULTS
Our search identified six records of five unique randomized controlled trials, of which two were published studies, one was in press, and two were abstract proceedings. There were 571 randomized participants, of whom 502 completed the trials. Mean age of participants was 64.6 years and mean prostate-specific antigen was 6.9 ng/mL. About 54.2% of participants had cT1c disease, 38.6% had cT2a-b disease, and 7.1 % had cT2c disease. Primary outcomes RS-RALP probably improves continence within one week after catheter removal (risk ratio (RR) 1.74, 95% confidence interval (CI) 1.41 to 2.14; I = 0%; studies = 4; participants = 410; moderate-certainty evidence). Assuming 335 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 248 more men per 1000 (137 more to 382 more) reporting continence recovery. RS-RALP may increase continence at three months after surgery compared to standard RALP (RR 1.33, 95% CI 1.06 to 1.68; I = 86%; studies = 5; participants = 526; low-certainty evidence). Assuming 750 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 224 more men per 1000 (41 more to 462 more) reporting continence recovery. We are very uncertain about the effects of RS-RALP on serious adverse events compared to standard RALP (RR 1.40, 95% CI 0.47 to 4.17; studies = 2; participants = 230; very low-certainty evidence). Secondary outcomes There is probably little to no difference in continence recovery at 12 months after surgery (RR 1.01, 95% CI 0.97 to 1.04; I = 0%; studies = 2; participants = 222; moderate-certainty evidence). Assuming 982 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 10 more men per 1000 (29 fewer to 39 more) reporting continence recovery. We are very uncertain about the effect of RS-RALP on potency recovery 12 months after surgery (RR 0.98, 95% CI 0.54 to 1.80; studies = 1; participants = 55; very low-certainty evidence). RS-RALP may increase PSMs (RR 1.95, 95% CI 1.19 to 3.20; I = 0%; studies = 3; participants = 308; low-certainty evidence) indicating a higher risk for prostate cancer recurrence. Assuming 129 per 1000 men undergoing standard RALP have positive margins, this corresponds to 123 more men per 1000 (25 more to 284 more) with PSMs. We are very uncertain about the effect of RS-RALP on BCRFS compared to standard RALP (hazard ratio (HR) 0.45, 95% CI 0.13 to 1.60; I = 32%; studies = 2; participants = 218; very low-certainty evidence).
AUTHORS' CONCLUSIONS
Findings of this review indicate that RS-RALP may result in better continence outcomes than standard RALP up to six months after surgery. Continence outcomes at 12 months may be similar. Downsides of RS-RALP may be higher positive margin rates. We are very uncertain about the effect on BCRFS and potency outcomes. Longer-term oncologic and functional outcomes are lacking, and no preplanned subgroup analyses could be performed to explore the observed heterogeneity. Surgeons should discuss these trade-offs and the limitations of the evidence with their patients when considering this approach.

Clinicians' recommendation for the human papillomavirus (HPV) vaccine appears to be an important driver of parental decisions about vaccination. Our aim was to synthesize the best available evidence exploring the perceptions and experiences regarding HPV vaccination, from the perspective of the US clinician. We conducted a comprehensive literature search of Academic Search Complete, CINAHL Plus, Communication & Mass Media Complete, Consumer Health Complete (EBSCOhost), ERIC, Health and Psychosocial Instruments, MEDLINE with full text, and PsycINFO databases. We identified 60 eligible articles: 48 quantitative and 12 qualitative. We extracted the following information: study purpose, use of theory, location, inclusion criteria, and health care provider classification. Results were organized into 5 categories: 1) clinicians' knowledge and beliefs about HPV and the HPV vaccine, 2) clinicians' attitudes and beliefs about recommending HPV vaccines, 3) clinicians' intention to recommend HPV vaccines, 4) clinicians' professional practices regarding HPV vaccination, and 5) patient HPV vaccination rates. Although clinicians were generally supportive of HPV vaccination, there was a discrepancy between clinicians' intentions, recommendation practices, and patient vaccination rates. Studies reported that clinicians tended not to provide strong, consistent recommendations, and were more likely to recommend HPV vaccines to girls versus boys and to older versus younger adolescents. Analyses revealed a number of facilitating factors and barriers to HPV vaccination at the clinician, parent/patient, and systems levels, including clinician knowledge, clinician beliefs, and office procedures that promote vaccination. This review provides an evidence base for multilevel interventions to improve clinician HPV vaccine recommendations and vaccination rates.

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.

BACKGROUND
Priapism is defined as a penile erection that persists four or more hours and is unrelated to sexual stimulation. Priapism resulting from hematologic malignancy is most likely caused by venous obstruction from microemboli/thrombi and hyperviscosity caused by the increased number of circulating leukocytes in mature and immature forms. In patients with leukemia, 50% of cases of priapism are due to Chronic Myeloid Leukemia (CML). We present a systematic review of priapism in CML. Acquisition of evidence: An extensive literature research was carried out in PubMed, Google Scholar, SCOPUS, and Science Citation Index databases... The search included cases up to 4th August 2020. Synthesis of evidence: A total of 68 articles were found and included in our review, including 3 reviews from three different centers. We found 68 articles (102 patients; figure 1) and several case reports on priapism in CML. Priapism was noticed in some patients at the first presentation of CML. However, it was infrequently reported during the start of treatment, following the stop of medication and post-splenectomy. The mean age at presentation was 27.4 years, and the mean time from onset of priapism to the time to get medical attention (presentation) was 78.2 hours. The mean white blood cell count associated with priapism was 321.29x109/L, and the mean platelet count was 569 x10 9/L. The chronic phase of CML was the most common phase where priapism occurred. Most patients were Asian (>50%). Nearly a quarter of patients (27.4%) developed permanent erectile dysfunction.
CONCLUSIONS
Priapism is a urological emergency requiring urgent multidisciplinary management to prevent erectile dysfunction. Because of the relatively rare occurrence of priapism in CML patients, there is no standard treatment protocol.

Review
BACKGROUND
Although anorectal malformations (ARMs) are frequently encountered, rare variants difficult to classify have been reported.
METHODS
This study describes a patient with ARM and rectopenile fistula. The literature was reviewed systematically to assess the anatomical characteristics, clinical presentations and operations of this rare type of ARM.
RESULTS
Eight patients were reported in the six included articles. In three patients, the fistula extended from the rectum to the anterior urethra without communication with the skin. In one patient, the fistula, located deep in corpus spongiosum, opened to the ventral aspect of the penis without communication with the urethra. In the remaining four patients, the fistula extended from the rectum to the cutaneous orifice in the ventral aspect of penis, with communication or a short common channel with the urethra.
CONCLUSIONS
Imperforate anus with fistula extending into the penis is a rare variant of anorectal malformation. Unawareness of this lesion resulted in a delay of correct diagnosis and appropriate management. A thorough examination, including colonourethrography and fistulography, should be performed in all patients with a fistula opening in the ventral aspect of the penis.
