Meta-Analysis
BACKGROUND
Infection is the most feared complication of a penile prosthesis. Diabetes mellitus (DM) is widely known to increase the risk of several infections, but its role in the penile prosthesis is still controversial. This systematic review aims to show the contemporary scenario of penile prosthesis infection and present a meta-analysis about DM contribution to penile prosthesis infection.
METHODS
The review was performed with no language or time limitation, including ten databases. The included articles were about the male population who received a penile prosthesis with no model restriction, with a minimum follow up of 1 year, and outcomes adequately reported.
RESULTS
The mean infection incidence of penile prosthesis ranged from 0.33 to 11.4%. In early 2000, the general incidence of infection was 3 to 5%, then, the introduction of coated materials decreased it to 0.3 to 2.7%. The meta-analysis showed that diabetes mellitus is related to an increased risk of penile prosthesis infection with an odds ratio of 1.53 (95% CI 1.15-2.04).
CONCLUSIONS
Penile prosthesis infection decreased in the last decades but remains a significant cause of reoperation, and it is related to lower prosthesis survival. Meta-analysis concludes that diabetes mellitus is related to a higher risk of penile prosthesis infection.

Neurourology and Urodynamics Feb 2020To systematically compare the impact of catheter-based bladder drainage methods on the rate of urinary tract infections (UTIs) amongst patients with neurogenic bladder.
AIMS
To systematically compare the impact of catheter-based bladder drainage methods on the rate of urinary tract infections (UTIs) amongst patients with neurogenic bladder.
METHODS
A search of Cochrane Library, Embase, Medline, and Grey literature to February 2019 was performed using methods prepublished on PROSPERO. Reporting followed the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Eligible studies were published in English and compared UTI incidence between neurogenic bladder patients utilizing bladder drainage methods of the indwelling urethral catheter (IUC), suprapubic catheter (SPC) or intermittent self-catheterization (ISC). The odds ratio of UTI was the sole outcome of interest.
RESULTS
Eight nonrandomized observational cohort studies were identified, totaling 2321 patients who utilized either IUC, SPC, or ISC. Studies enrolled patients with neurogenic bladder due to spinal cord injury (seven studies) or from any cause (one study). UTI rates were compared between patients utilizing IUC vs SPC (four studies), IUC vs ISC (six studies), and SPC vs ISC (four studies). Compared with IUC, five of six studies suggested ISC use was associated with lower rates of UTI. Studies comparing IUC vs SPC and SPC vs ISC gave mixed results. Meta-analysis was not appropriate due to study methodology heterogeneity.
CONCLUSIONS
Low-level evidence suggests amongst patients with neurogenic bladder requiring catheter-based drainage, the use of ISC is associated with lower rates of UTI than IUC. Comparisons of IUC vs SPC and SPC vs ISC gave mixed results. Future randomized trials are required to confirm these findings.

Meta-Analysis
PURPOSE
The aim of this study was to identify the factors associated with infection in patients who undergo penile prosthesis implantation.
METHODS
We performed a systematic review/meta-analysis, including clinical trials, quasi-experiments, retrospective and prospective cohort studies, and case-control studies. Searching was done in CENTRAL, MEDLINE, and EMBASE databases. Participants were patients who had erectile dysfunction, regardless of the etiology, and underwent penile prosthesis implantation. Two researchers reviewed each reference by title and abstract. The statistical analysis was performed using Review Manager 5.3 (RevMan® 5.3).
RESULTS
A total of 513 studies were found with the search strategies. After excluding duplicates, 40 studies with a total of 175,592 patients were included in the qualitative and quantitative analysis. Among patient characteristics, we found that diabetes mellitus and immunosuppression appear to have increase odds of infection. Related to the procedure, infection-retardant-coated penile prosthesis and primary (first) surgery appear to lower odds of infection.
CONCLUSIONS
Diabetes mellitus and immunosuppression were associated with increased infection rates; infection-retardant coating of the prosthesis and primary surgery were associated with reduced infection rates.

Meta-Analysis Review
Little is known about the ongoing monkeypox (mpox) outbreak, and the clinical features of mpox in patients worldwide have not been rigorously analysed. Thus, we aimed to investigate the clinical features associated with mpox infection and understand the pathophysiology and characteristics of the disease. For this systematic review and meta-analysis, we searched PubMed/MEDLINE, Embase, CINAHL, Google Scholar, and the Cochrane Database of Systematic Reviews for articles published till 16 September 2022. We used a random effects model to calculate the pooled prevalence and 95% confidence interval (CI). We used the I statistic to assess heterogeneity, Egger's test to assess publication bias, 95% prediction interval to determine the level of uncertainty, and the Newcastle-Ottawa Scale and Joanna Briggs Institute quality assessment tool to assess the risk of bias. Twenty-six relevant articles from 19 countries across 5 continents were included, and data on 5472 mpox patients with 18 unique features were analysed. The pooled prevalence of clinical features of mpox were rash (85.7%, 95% CI: 68.3-94.3; k = 21), chills (77.8%, 95% CI: 70.5-83.7; k = 3), and fever (62.3%, 95% CI: 51.3-71.6; k = 25), lymphadenopathy (58.6%, 95% CI: 47.2-69.2; k = 21), lethargy or exhaustion (46.8%, 95% CI: 30.7-63.5; k = 14), pruritus (40.6%, 95% CI: 28.5-54.0; k = 5), myalgia (36.0%, 95% CI: 24.3-49.7; k = 16), headache (34.6%, 95% CI: 23.4-47.8; k = 17), skin ulcer (31.1%, 95% CI: 18.6-47.1; k = 7), abdomen symptom (24.2%, 95% CI: 17.9-31.9; k = 11), pharyngitis (23.0%, 95% CI: 12.7-37.9; k = 14), respiratory symptom (19.5%, 95% CI: 6.8-44.6; k = 6), nausea or vomiting (13.0%, 95% CI: 4.6-31.9; k = 3), scrotal or penile oedema (10.7%, 95% CI: 6.3-17.7; k = 4), conjunctivitis (7.1%, 95% CI: 2.4-18.9; k = 6), and death (0.9%, 95% CI: 0.4-2.0; k = 26). This is the first international and comprehensive study to examine all clinical presentations of human mpox infection. Our systematic review proposes a comprehensive understanding of the current mpox outbreak and may serve as key data for future studies on the pathological mechanisms and epidemiology of mpox infections.

Meta-Analysis
BACKGROUND
Urinary catheterisation is a common procedure, with approximately 15% to 25% of all people admitted to hospital receiving short-term (14 days or less) indwelling urethral catheterisation at some point during their care. However, the use of urinary catheters is associated with an increased risk of developing urinary tract infection. Catheter-associated urinary tract infection (CAUTI) is one of the most common hospital-acquired infections. It is estimated that around 20% of hospital-acquired bacteraemias arise from the urinary tract and are associated with mortality of around 10%. This is an update of a Cochrane Review first published in 2005 and last published in 2007.
OBJECTIVES
To assess the effects of strategies for removing short-term (14 days or less) indwelling catheters in adults.
SEARCH METHODS
We searched the Cochrane Incontinence Specialised Register, which contains trials identified from CENTRAL, MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP, and handsearching of journals and conference proceedings (searched 17 March 2020), and reference lists of relevant articles.
SELECTION CRITERIA
We included all randomised controlled trials (RCTs) and quasi-RCTs that evaluated the effectiveness of practices undertaken for the removal of short-term indwelling urethral catheters in adults for any reason in any setting.
DATA COLLECTION AND ANALYSIS
Two review authors performed abstract and full-text screening of all relevant articles. At least two review authors independently performed risk of bias assessment, data abstraction and GRADE assessment.
MAIN RESULTS
We included 99 trials involving 12,241 participants. We judged the majority of trials to be at low or unclear risk of selection and detection bias, with a high risk of performance bias. We also deemed most trials to be at low risk of attrition and reporting bias. None of the trials reported on quality of life. The majority of participants across the trials had undergone some form of surgical procedure. Thirteen trials involving 1506 participants compared the removal of short-term indwelling urethral catheters at one time of day (early morning removal group between 6 am to 7 am) versus another (late night removal group between 10 pm to midnight). Catheter removal late at night may slightly reduce the risk of requiring recatheterisation compared with early morning (RR 0.71, 95% CI 0.53 to 0.96; 10 RCTs, 1920 participants; low-certainty evidence). We are uncertain if there is any difference between early morning and late night removal in the risk of developing symptomatic CAUTI (RR 1.00, 95% CI 0.61 to 1.63; 1 RCT, 41 participants; very low-certainty evidence). We are uncertain whether the time of day makes a difference to the risk of dysuria (RR 2.20; 95% CI 0.70 to 6.86; 1 RCT, 170 participants; low-certainty evidence). Sixty-eight trials involving 9247 participants compared shorter versus longer durations of catheterisation. Shorter durations may increase the risk of requiring recatheterisation compared with longer durations (RR 1.81, 95% CI 1.35 to 2.41; 44 trials, 5870 participants; low-certainty evidence), but probably reduce the risk of symptomatic CAUTI (RR 0.52, 95% CI 0.45 to 0.61; 41 RCTs, 5759 participants; moderate-certainty evidence) and may reduce the risk of dysuria (RR 0.42, 95% CI 0.20 to 0.88; 7 RCTs; 1398 participants; low-certainty evidence). Seven trials involving 714 participants compared policies of clamping catheters versus free drainage. There may be little to no difference between clamping and free drainage in terms of the risk of requiring recatheterisation (RR 0.82, 95% CI 0.55 to 1.21; 5 RCTs; 569 participants; low-certainty evidence). We are uncertain if there is any difference in the risk of symptomatic CAUTI (RR 0.99, 95% CI 0.60 to 1.63; 2 RCTs, 267 participants; very low-certainty evidence) or dysuria (RR 0.84, 95% CI 0.46 to 1.54; 1 trial, 79 participants; very low-certainty evidence). Three trials involving 402 participants compared the use of prophylactic alpha blockers versus no intervention or placebo. We are uncertain if prophylactic alpha blockers before catheter removal has any effect on the risk of requiring recatheterisation (RR 1.18, 95% CI 0.58 to 2.42; 2 RCTs, 184 participants; very low-certainty evidence) or risk of symptomatic CAUTI (RR 0.20, 95% CI 0.01 to 4.06; 1 trial, 94 participants; very low-certainty evidence). None of the included trials investigating prophylactic alpha blockers reported the number of participants with dysuria.
AUTHORS' CONCLUSIONS
There is some evidence to suggest the removal of indwelling urethral catheters late at night rather than early in the morning may reduce the number of people who require recatheterisation. It appears that catheter removal after shorter compared to longer durations probably reduces the risk of symptomatic CAUTI and may reduce the risk of dysuria. However, it may lead to more people requiring recatheterisation. The other evidence relating to the risk of symptomatic CAUTI and dysuria is too uncertain to allow us to draw any conclusions. Due to the low certainty of the majority of the evidence presented here, the results of further research are likely to change our findings and to have a further impact on clinical practice. This systematic review has highlighted the need for a standardised set of core outcomes, which should be measured and reported by all future trials comparing strategies for the removal of short-term urinary catheters. Future trials should also study the effects of short-term indwelling urethral catheter removal on non-surgical patients.

Meta-Analysis Review
PURPOSE
This systematic review was done to compare the effectiveness of infection retardant coated inflatable penile prostheses vs noncoated devices.
MATERIALS AND METHODS
We systematically reviewed PubMed® and Galileo® to identify all relevant case studies. The postoperative infection incidence rate was compared for coated and noncoated inflatable penile prostheses to determine whether coating the implant affects the rate of surgical implant infection.
RESULTS
Included in analysis were 14 clinical case studies in a total of 9,910 patients with a first time implant, including 5,214 inflatable penile prostheses without an infection retardant coating and 4,696 coated inflatable penile prostheses impregnated with minocycline/rifampin (3,158), rifampin/gentamycin immersion (181), vancomycin/gentamycin immersion (181) and a hydrophilic coating only (1,176). For noncoated vs coated prostheses the infection rate was 2.32% vs 0.89% (p <0.01), including 0.63%, 0.55%, 4.42% and 1.11% for minocycline/rifampin, rifampin/gentamycin immersion, vancomycin/gentamycin immersion and hydrophilic coatings, respectively.
CONCLUSIONS
This analysis documents a significant advantage of using coated compared to noncoated inflatable penile prostheses to prevent postoperative device infection. Infection retardant coatings that allow antibiotics to elute off the device components decrease the incidence of device infection by approximately 50%. Future studies must address novel techniques, such as preventing bacterial adhesion, to further decrease infectious etiologies.

Review
INTRODUCTION
Hemoglobin A1c (HbA1c), a glycated form of hemoglobin, develops when glucose is elevated in the blood. It is used as a marker of how well a diabetic patient has been controlling their blood sugar over the previous 3-4 months. Some use HbA1c as a predictor of infection risk during prosthetic surgery, and many surgeons require patients to lower it preoperatively.
OBJECTIVE
This study was designed to comprehensively review the literature relating HbA1c and penile prosthesis (PP).
METHODS
A PubMed search of English-language articles identified studies that investigate the relationship between HbA1c levels and PP infection. Studies were only included if they reported the mean HbA1c of all PP patients and compared patients who did/did not develop a prosthetic infection. References from relevant articles are included.
RESULTS
A total of 6 studies, 1992-2020, were identified. 2 studies occurred before the advent of antibiotic-enhanced devices in the early 2000s and have limited applicability to the modern era. Of the 4 studies published after, 2 reported a significant difference in mean HbA1c when comparing patients who developed a prosthetic infection and those who did not (9.1% vs 7.5%, P = .000 and 9.5% vs 7.8%, P < .001). The other 2 studies reported no significant difference in mean HbA1c when comparing patients who developed a prosthetic infection and those who did not (7.0% vs 7.6%, P > .05; and 7.6% vs 7.5%, P = .598).
CONCLUSION
Current data regarding HbA1c as a predictor of PP infection are inconclusive, with no consensus. HbA1c is increasingly used as a predictor of postsurgical prosthetic infection, with some urologists requiring patients with elevated HbA1c to acutely lower it before elective surgery. While there are a number of established health benefits of controlling elevated blood sugar, larger randomized controlled trials need to validate whether acutely lowering perioperative HbA1c decreases risk of prosthetic infection.

European Urology Focus Dec 2023There are several procedures for surgical nodal staging in clinically node-negative (cN0) penile carcinoma. (Review)
Review
CONTEXT
There are several procedures for surgical nodal staging in clinically node-negative (cN0) penile carcinoma.
OBJECTIVE
To evaluate the diagnostic accuracy, perioperative outcomes, and complications of minimally invasive surgical procedures for nodal staging in penile carcinoma.
EVIDENCE ACQUISITION
A systematic review of the Medline, Embase, and Cochrane controlled trials databases and ClinicalTrials.gov was conducted. Published and ongoing studies reporting on the management of cN0 penile cancer were included without any design restriction. Outcomes included the false negative (FN) rate, the number of nodes removed, surgical time, and postoperative complications.
EVIDENCE SYNTHESIS
Forty-one studies were eligible for inclusion. Four studies comparing robot-assisted (RA-VEIL) and video-endoscopic inguinal lymphadenectomy (VEIL) to open inguinal lymph node dissection (ILND) were suitable for meta-analysis. A descriptive synthesis was performed for single-arm studies on modified open ILND, dynamic sentinel node biopsy (DSNB) with and without preoperative inguinal ultrasound (US), and fine-needle aspiration cytology (FNAC). DSNB with US + FNAC had lower FN rates (3.5-22% vs 0-42.9%) and complication rates (Clavien Dindo grade I-II: 1.1-20% vs 2.9-11.9%; grade III-V: 0-6.8% vs 0-9.4%) in comparison to DSNB alone. Favourable results were observed for VEIL/RA-VEIL over open ILND in terms of major complications (2-10.6% vs 6.9-40.6%; odds ratio [OR] 0.18; p < 0.01). Overall, VEIL/RA-VEIL had lower wound-related complication rates (OR 0.14; p < 0.01), including wound infections (OR 0.229; p < 0.01) and skin necrosis (OR 0.16; p < 0.01). The incidence of lymphatic complications varied between 20.6% and 49%.
CONCLUSIONS
Of all the surgical staging options, DSNB with inguinal US + FNAC had the lowest complication rates and high diagnostic accuracy, especially when performed in high-volume centres. If DSNB is not available, favourable results were also found for VEIL/RA-VEIL over open ILND. Lymphatic-related complications were comparable across open and video-endoscopic ILND.
PATIENT SUMMARY
We reviewed studies on different surgical approaches for assessing lymph node involvement in cases with penile cancer. The results show that a technique called dynamic sentinel node biopsy with ultrasound guidance and fine-needle sampling has high diagnostic accuracy and low complication rates. For lymph node dissection in penile cancer cases, a minimally invasive approach may offer favourable postoperative outcomes.

Meta-Analysis Review
BACKGROUND AND AIM
Recent trends have shown a decline in the rates of human papillomavirus (HPV)-associated cervical cancer in the vaccinated population but there has been a spike in the HPV-associated oropharyngeal, anal and penile cancers in the majority of the unvaccinated population which are young and middle-aged males. Indigenous populations at an international level carry a disproportionate burden of most diseases. The aim of this meta-analysis was to ascertain the worldwide prevalence of HPV infection in Indigenous populations stratified by sex and site and to document the most commonly reported HPV types.
METHODS
Published articles on HPV infection in Indigenous populations from PubMed, Scopus, EMBASE and Web of Science were systematically searched from inception until 23 December 2019.
RESULTS
A total of 41 studies were included in the final analysis. The pooled worldwide prevalence of HPV infection (for both oral and genital sites, both males and females) in Indigenous populations was 34.2% (95% CI: 28.9%-39.8%). Subgroup analysis (geographical) showed that the pooled prevalence for African Indigenous, American Indigenous and Asian-Oceanic Indigenous populations were 33.0% (95% CI: 12.8%-57.1%), 33.0% (95% CI: 27.4%-38.9%) and 33.3% (95% CI: 0.17.5%-51.3%), respectively.
CONCLUSION
There are not enough data on the burden of the infection carried by males especially with respect to highly suspicious sites like oropharynx. Also, we conclude an overall high prevalence of HPV infection in the Indigenous populations and increasing their susceptibility to benign and malignant manifestations of HPV.

Review
Since May 2022, there has been a global increase in the number of Mpox virus (MPXV) cases in countries that were previously considered non-endemic. In July 2022, the World Health Organization (WHO) declared this outbreak a public health emergency of international concern. The objective of this systematic review is to examine the novel clinical features of Mpox and to assess the available treatment options for managing the disease in patients who are afflicted with it. We conducted a systematic search in several databases, including PubMed, Google Scholar, Cochrane Library, and the grey literature, from May 2022 to February 2023. We identified 21 eligible studies, which included 18,275 Mpox cases, for final qualitative analysis. The majority of cases were reported in men who have sex with men (MSM) and immunocompromised individuals with HIV (36.1%). The median incubation period was 7 days (IQR: 3-21). The novel clinical manifestations include severe skin lesions on the palms, oral and anogenital regions, as well as proctitis, penile edema, tonsillitis, ocular disease, myalgia, lethargy, and sore throat, without any preceding prodromal symptoms or systemic illness. In addition, fully asymptomatic cases were documented, and various complications, including encephalomyelitis and angina, were noted. Clinicians must be familiar with these novel clinical characteristics, as they can aid in testing and tracing such patients, as well as asymptomatic high-risk populations such as heterosexuals and MSM. In addition to supportive care, currently, there are several effective prophylactic and treatment strategies available to combat Mpox, including the vaccines ACAM2000 and MVA-BN7, as well as the immunoglobulin VIGIV and the antivirals tecovirimat, brincidofovir, and cidofovir against severe Mpox infection.
