Genital lymphedema (GL) is an uncommon and disabling disease that manifests as enlargement of the genital region resulting from the disturbance of lymphatic drainage. Although conservative treatment such as decompression is typically the first-line approach, surgical intervention has been shown to be effective in certain cases. This study aimed to systematically review studies evaluating available surgical alternatives for the treatment of male GL. A systematic search strategy using keyword and subject headings was applied to PubMed, Scopus, EMBASE, and Cochrane Library in May 2019. Studies investigating various surgical techniques to treat penile and scrotal lymphedema were included. The potential risk of bias of included trials was evaluated using the methodological index for non-randomized studies (MINORS). In total, 13 studies met the inclusion criteria, nine of which were determined to be high-quality. The average MINORS score was 12.45 for studies involving excision and 14 for studies involving lymphovenous anastomosis (LVA). The most common reason for a low score was a failure to describe the inclusion criteria. Recurrence of lymphedema during follow-up was reported in four studies involving excision and in no studies involving LVA. In general, the quality of the included literature was considered to be fair. Although surgical intervention might not always prevent the recurrence of lymphedema, all of the studies reported improved quality of life after the procedure. This study could be used as the basis for evidence-based guidelines to be applied in clinical practice for managing male GL.

Meta-Analysis
BACKGROUND
Sickle cell disease comprises a group of genetic haemoglobin disorders. The predominant symptom associated with sickle cell disease is pain resulting from the occlusion of small blood vessels by abnormally 'sickle-shaped' red blood cells. There are other complications, including chronic organ damage and prolonged painful erection of the penis, known as priapism. Severity of sickle cell disease is variable, and treatment is usually symptomatic. Priapism affects up to half of all men with sickle cell disease, however, there is no consistency in treatment. We therefore need to know the best way of treating this complication in order to offer an effective interventional approach to all affected individuals. This is an update of a previously published review.
OBJECTIVES
To assess the benefits and risks of different treatments for stuttering (repeated short episodes) and fulminant (lasting for six hours or more) priapism in sickle cell disease.
SEARCH METHODS
We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register, which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. We also searched trial registries. Date of the most recent search of the Group's Haemoglobinopathies Trials Register: 09 September 2019. Date of most recent search of trial registries and of Embase: 01 October 2019.
SELECTION CRITERIA
All randomised or quasi-randomised controlled trials comparing non-surgical or surgical treatment with placebo or no treatment, or with another intervention for stuttering or fulminant priapism.
DATA COLLECTION AND ANALYSIS
The authors independently extracted data and assessed the risk of bias of the trials.
MAIN RESULTS
Three trials with 102 participants were identified and met the criteria for inclusion in this review. These trials compared stilboestrol to placebo, sildenafil to placebo and a four-arm trial which compared ephedrine or etilefrine to placebo and ranged in duration from two weeks to six months. All of the trials were conducted in an outpatient setting in Jamaica, Nigeria and the UK. None of the trials measured our first primary outcome, detumescence. However, all three trials reported on the reduction in frequency of stuttering priapism, our second primary outcome; and from the evidence included in this review, we are uncertain whether stilboestrol, etilefrine or ephedrine reduce the frequency of stuttering priapism as the certainty of the evidence has been assessed as very low. Additionally, we conclude that sildenafil may make little or no difference (low-certainty evidence). Two trials reported on immediate side effects and we are uncertain whether etilefrine or ephedrine reduce the occurrence of these (very low-certainty of evidence) and also conclude that sildenafil may make little or no difference in side effects (low-quality evidence). Given that all of the trials were at risk of bias and all had low participant numbers, we considered the certainty of the evidence to be low to very low.
AUTHORS' CONCLUSIONS
There is a lack of evidence for the benefits or risks of the different treatments for both stuttering and fulminant priapism in sickle cell disease. This systematic review has clearly identified the need for well-designed, adequately-powered, multicentre randomised controlled trials assessing the effectiveness of specific interventions for priapism in sickle cell disease.

INTRODUCTION
Hair-thread strangulation syndrome describes the constriction of a body part by a tightly wound hair or thread. This research aims to review the literature about this entity.
METHODS
A systematic review was performed to characterise hair-thread strangulation syndrome in subjects aged ≤16 years. This pre-registered review (PROSPERO ID: CRD42022363996) followed the PRISMA methodology.
RESULTS
Subjects with digital strangulation were significantly younger (median = 4.0 [interquartile range: 2.0-6.1] months; n = 143) than females with genital strangulation (9.0 [6.8-11] years; n = 36), males with genital strangulation (5.1 [1.9-8.0] years; n = 36), and subjects with non-digital and non-genital strangulation (24 [13-48] months; n = 11). Digital strangulation was followed by an amputation in five (3.5%) and a reconstructive surgical intervention in seven (4.9%) cases. Sequelae occurred in four (11%) cases after female genital strangulation: clitoris autoamputation (n = 2) and surgical removal of a necrotic labium minus (n = 2). Severe complications were observed in 14 (39%) cases with male genital strangulation: urethral fistula (n = 7), urethral transection (n = 2), and partial penile autoamputation (n = 5). A partial uvular autoamputation was observed in one case (9.0%) with non-digital and non-genital strangulation.
CONCLUSIONS
Early recognition and management are crucial to avoid sequelae or long-term care in hair-thread strangulation syndrome.

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.

Meta-Analysis
Erectile dysfunction (ED) is a major global health burden commonly observed in patients with end-stage renal disease (ESRD). Although renal transplantation improves the problem in some patients, it persists in ≈20-50% of recipients. Studies regarding the effects of kidney transplantation on ED present contradictory findings. We performed a systematic review to summarise the effects of kidney transplantation on ED. A systematic literature search was performed across PubMed, Cochrane, and Scopus databases in April 2020. We included all prospective studies that investigated the pre and posttransplant international index of erectile function (IIEF-5) scores in recipients with ED. Data search in PubMed and Google Scholar produced 1326 articles; eight were systematically reviewed with a total of 448 subjects. Meta-analysis of IIEF-5 scores showed significant improvements between pre and post transplantation. Our findings confirm that renal transplantation improves erectile function. Furthermore, transplantation also increases testosterone level. However, the evidence is limited because of the small number of studies. Further studies are required to investigate the effects of renal transplantation on erectile function.

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.

Peyronie's disease (PD) is characterized by abnormal penile curvature, and various surgical methods have been developed using different graft materials. However, there is currently no universal agreement on which type of graft is the best. The objective of this review was to evaluate the available literature and identify the most effective graft material for penile curvature correction in PD. A literature search was conducted using electronic databases, including PubMed, Scopus, and the Cochrane Library. The patients, intervention, comparison, and outcome (PICO) approach was used to define the eligibility of studies. Two authors independently selected studies, evaluated them, and extracted data. Random-effect models using the DerSimonian-Laird method were used. Most studies were single-arm studies and had a high risk of bias. Buccal mucosa grafts (BMG) were found to result in the highest penile straightening rates and were associated with the least de novo erectile dysfunction. TachoSil grafts demonstrated a high success rate in straightening despite a higher mean preoperative curvature, while Tutoplast grafts had a higher incidence of postoperative erectile dysfunction. BMG had the highest percentage of postoperative penile straightening. Overall, the TachoSil graft showed the best performance when preoperative curvature is taken into account. Based on the available literature, BMG appear to be the most effective for penile curvature correction in PD, but this is offset by the requirement for low preoperative curvature. The TachoSil graft shows the best overall performance when preoperative curvature is considered. Comparative randomized clinical trials are still needed to determine graft superiority.

Meta-Analysis
BACKGROUND
Adolescent girls and young women (AGYW) are at high risk of sexually transmitted infections (STIs). It is unknown whether beginning to have sexual intercourse results in changes to immune mediators in the cervicovaginal tract that contribute to this risk.
METHODS
We collected cervicovaginal lavages from Kenyan AGYW in the months before and after first penile-vaginal sexual intercourse and measured the concentrations of 20 immune mediators. We compared concentrations pre- and post-first sex using mixed effect models. We additionally performed a systematic review to identify similar studies and combined them with our results by meta-analysis of individual participant data.
RESULTS
We included 180 samples from 95 AGYW, with 44% providing only pre-first sex samples, 35% matched pre and post, and 21% only post. We consistently detected 19/20 immune mediators, all of which increased post-first sex (p<0.05 for 13/19; Holm-Bonferroni-adjusted p<0.05 for IL-1β, IL-2, and CXCL8). Effects remained similar after excluding samples with STIs and high Nugent scores. Concentrations increased cumulatively over time after date of first sex, with an estimated doubling time of about 5 months.Our systematic review identified two eligible studies, one of 93 Belgian participants, and the other of 18 American participants. Nine immune mediators were measured in at least two-thirds of studies. Meta-analysis confirmed higher levels post-first sex for 8/9 immune mediators (p<0.05 for six mediators, most prominently IL-1α, IL-1β, and CXCL8).
CONCLUSIONS
Cervicovaginal immune mediator concentrations were higher in women who reported that they started sexual activity. Results were consistent across three studies conducted on three different continents.

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.

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.
