Review
INTRODUCTION
Penile Mondor's Disease (PMD) is a rare illness that causes thrombophlebitis in the superficial veins of the penis that is manifested by transient pain and swelling. PMD often is associated with trauma to the penis, prolonged or vigorous sexual intercourse, and has been linked to genetics.
OBJECTIVES
Our aim is to review the current literature on PMD.
METHODS
A comprehensive literature search of English and Turkish publications on PMD was found through PubMed and Web of Science using various keywords. It is a systematic review.
RESULTS
PMD might be an uncommon, harmless condition that normalizes with moderate therapy or potentially clinical therapy. Its pathogenesis has not yet been completely explained; however, different etiological variables are known. The current studies on PMD are summarized.
CONCLUSION
Analyses are frequently made with a fair history and actual assessment. In any case, education on the illness is needed. Furthermore, the identification should be supported by ultrasonography. In a greater part of the patients, results are acquired with 2 months of clinical treatment. In exceptionally uncommon cases, careful thrombectomy or expulsion of the superficial vein is required.

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.

BACKGROUND
Primary mucosal melanomas (PMMs) are rare and clinically heterogeneous, including head and neck (HNMs), vulvovaginal (VVMs), conjunctival (CjMs), anorectal (ARMs) and penile (PMs) melanomas. While the prognosis of advanced cutaneous melanoma has noticeably improved using treatments with immune checkpoint inhibitors (ICIs) and molecules targeting BRAF and MEK, few advances have been made for PMMs because of their poorer response to ICIs and their different genetic profile. This prompted us to conduct a systematic review of molecular studies of PMMs to clarify their pathogenesis and potential therapeutic targets.
METHODS
All articles that examined gene mutations in PMMs were identified from the databases and selected based on predefined inclusion criteria. Mutation rate was calculated for all PMMs and each location group by relating the number of mutations identified to the total number of samples analysed.
RESULTS
Among 1,581 studies identified, 88 were selected. Overall, the frequency of KIT, BRAF and NRAS mutation was 13.5%, 12.9% and 12.1%, respectively. KIT mutation ranged from 6.4% for CjMs to 16.6% for ARMs, BRAF mutation from 8.6% for ARMs to 31.1% for CjMs, and NRAS mutation from 6.2% for ARMs to 18.5% for CjMs. Among 101 other genes analysed, 33 had mutation rates over 10%, including TTN, TSC1, POM121, NF1, MTOR and SF3B1.
CONCLUSION
In addition to BRAF, NRAS and KIT genes commonly studied, our systematic review identified significantly mutated genes that have already been associated (e.g., TSC1, mTOR, POLE or ATRX) or could be associated with (future) targeted therapies.

Meta-Analysis Review
Treatment recommendations of penile cancers are determined primarily by the local extent of the primary tumor. Clinical palpation is used for local staging. We reviewed diagnostic performance of MRI in local staging of penile cancer in three clinical scenarios (questions [Qs] 1 through 3, Q1-Q3) and one imaging scenario (Q4). Q1 asked whether MRI reliably distinguishes ≤ T1 from ≥ T2 disease. Q2 asked whether clinical staging reliably identifies ≤ T1 versus ≥ T2 disease and how clinical staging compares to MRI. Q3 asked if MRI is accurate for diagnosis of T3 disease. Q4 asked if artificial erection (by intracavernosal injection of prostaglandin E) improved accuracy of MRI in T categorization. MEDLINE, EMBASE, and Cochrane Library databases were searched through September 13, 2021, for studies evaluating local staging of penile cancer using MRI with surgical pathology as the reference standard. Diagnostic accuracy was calculated using a bivariate random-effects model and hierarchic summary ROC mode Meta-regression was performed to test for covariate effects of MRI and artificial erection in Q3 and Q4, respectively. Eight studies and 481 patients were included. The sensitivity and specificity of MRI for Q1 were 86% (95% CI, 73-94%) and 89% (95% CI, 77-95%), respectively. AUC for MRI (0.94; 95% CI, 0.92-0.96) did not differ from clinical staging (0.87; 95% CI, 0.84-0.90; = .83). For Q3, MRI had sensitivity and specificity of 80% (95% CI, 70-87%) and 96% (95% CI, 85-99%), respectively. For Q4, sensitivity and specificity for MRI with versus without artificial erection were 85% (95% CI, 71-92%) and 93% (95% CI, 77-98%) versus 86% (95% CI, 68-95%) and 84% (95% CI, 70-93%), respectively ( = .50). MRI staging of penile cancer may be considered for ≤ T1 versus ≥ T2 disease but did not appear more accurate than clinical staging. High specificity of MRI for diagnosis of ≥ T3 disease suggests that MRI may be useful when organ-sparing approaches are planned. MRI with and without artificial erection showed similar accuracy in local staging. MRI, with or without artificial erection, may be valuable in routine preoperative evaluation of local staging of penile cancer, particularly when organ-sparing options are considered.

The Journal of Sexual Medicine May 2022In 2016, we reported the first case of high flow priapism and arteriocavernosal fistula caused by penile prosthesis insertion that mimicked device autoinflation. (Review)
Review
BACKGROUND
In 2016, we reported the first case of high flow priapism and arteriocavernosal fistula caused by penile prosthesis insertion that mimicked device autoinflation.
AIM
To raise awareness amongst implanters, we describe further cases from our institution and perform a systematic review of the literature to understand the rarity of this phenomenon.
METHODS
Patient demographics, management and outcomes were extracted retrospectively. A systematic search of the EMBASE, PubMed and PubMed Central libraries for studies reporting arteriocavernosal fistula mimicking autoinflation since 1946 was performed.
OUTCOMES
To identify and report all known cases of high flow priapism and arteriocavernosal fistula presenting as autoinflation of an inflatable penile prosthesis.
RESULTS
Four patients in total (median age 56, range 46-60 years) were identified. Catastrophic bleeding (1.8L) occurred during revision surgery for presumed autoinflation in Patient 1 and subsequent ultrasound (US) confirmed a fistula which was embolized. Patient 2 redeveloped autoinflation following revision surgery. Ultrasound confirmed high flow priapism from an arteriocavernosal fistula. Patient 3 underwent penile magnetic resonance imaging (MRI) to investigate autoinflation and residual penile curvature. MRI showed a tumescent penis despite a deflated device and the fistula was embolized successfully. Patient 4 with sleep-related painful erections did not improve following insertion of penile prosthesis. Doppler US identified 2 fistulae that was embolized but with no resolution of symptoms. Subsequent embolization of both common penile arteries were done to control his symptoms. No other publications apart from the published abstract from 2016 reporting patient 1 was found.
CLINICAL IMPLICATIONS
If considered prior to revision surgery, the fistula can be managed safely by minimally invasive percutaneous angioembolisation avoiding surgery which can potentially be associated with significant complications.
STRENGTHS AND LIMITATIONS
The rarity of this phenomenon was supported by a systematic review. Our study however does present the findings from a small number of patients.
CONCLUSION
Damage to the cavernosal artery during inflatable penile prosthesis insertion can create an arteriocavernosal fistula that mimics autoinflation, leading to catastrophic intra-operative bleeding or unnecessary surgery.

INTRODUCTION
Penile modeling to correct the penile curvature in Peyronie's disease (PD) may be achieved manually (intra-operatively or post-injection) or by using assisted devices (penile traction, vacuum device, or penile prosthesis).
OBJECTIVES
To evaluate the efficacy, safety, and satisfaction associated with penile modeling in patients with PD.
METHODS
A PROSPERO registered (CRD42021241729) systematic search in MEDLINE and Cochrane Library was done following PRISMA. PICO: Studies were deemed eligible if they assessed patients with PD (P) undergoing modeling procedures (I) with or without a comparative group(C) evaluating the efficacy, safety, or patient satisfaction (O). Retrospective and prospective primary studies were included. The primary outcome measure is the change in penile curvature after modeling. The secondary outcome measures are the change in stretched penile length, adverse events, and patient satisfaction after modeling.
RESULTS
A total of 23 studies, involving 1,238 patients were included. Most studies (13, 56.5%) evaluated penile traction therapy. The studies were of low and intermediate quality (mean Newcastle-Ottawa Scale score of 5.7 and mean Jadad score of 3.3) with a mean level of evidence of 3.4. The mean penile curvature at baseline was between 31 and 80.8 degrees. Nine (39.1%) studies found a significant improvement (P < .05) of penile curvature after penile modeling, ranging between 11.7, and 37.2 degrees. An increase in mean stretched penile length was reported in 7 (30.4%) articles, varying between 0.4, and 1.8 cm. Serious complications such as penile prosthesis malfunctions (3.3-11.1%) and urethral injuries (2.9%) were only reported for intra-operative manual modeling.
CONCLUSION
Although individual studies have noted improvement in penile curvature and stretched penile length, specific recommendations regarding penile modeling in PD cannot be provided due to limited evidence available. Further RCTs with adequate sample size, validated assessment tools, and longer follow-up are needed. Krishnappa P, Manfredi C, Sinha M et al.

Meta-Analysis
OBJECTIVE
The purpose of the current study was to evaluate the diagnostic accuracies of 18F-FDG PET/CT for detection of lymph node (LN) metastasis in penile cancer (PeCA) patients through a systematic review and meta-analysis.
PATIENTS AND METHODS
The PubMed, Cochrane database, and Embase database, from the earliest available date of indexing through August 31, 2021, were searched for studies evaluating diagnostic performance of 18F-FDG PET/CT for detection of metastatic LN in PeCA patients. We determined the sensitivities and specificities across studies, calculated positive and negative likelihood ratios (LR+ and LR-, respectively), and constructed summary receiver operating characteristic curves.
RESULTS
Across 12 studies (479 patients), the pooled sensitivity of 18F-FDG PET/CT was 0.87 (95% confidence interval [CI], 0.79-0.92) and the pooled specificity was 0.88 (95% CI, 0.79-0.93). Likelihood ratio syntheses gave an overall LR+ of 7.2 (95% CI, 3.9-13.1) and LR- of 0.15 (95% CI, 0.1-0.24). The pooled diagnostic odds ratio was 47 (95% CI, 19-116). In meta-regression analysis, no variable was the source of the study heterogeneity.
CONCLUSIONS
18F-FDG PET/CT showed a good diagnostic performances for detection of metastatic LN in PeCA patients. Also, 18F-FDG PET/CT revealed similar diagnostic accuracy for detection of inguinal and pelvic LN metastasis in PeCA patients.

Meta-Analysis
INTRODUCTION
This study aimed to evaluate the efficacy and safety of Hyperbaric Oxygen Therapy (HBOT) use in hypospadias repair through systematic review and meta-analysis of comparative studies.
METHODS
A systematic literature search was performed in May 2021. Comparative studies assessing the surgical outcome of hypospadias repair between control versus HBOT utilization were identified and evaluated according to Cochrane collaboration recommendations. The assessed outcome includes hypospadias repair failures and graft failure for staged repair using a buccal graft. Relative risk with corresponding 95% confidence intervals (CI) were extrapolated. A random-effect model was used to generate pooled effect estimates. Heterogeneity and inter-study variability were assessed using Chi-square and I-square. Subgroup analysis was performed according to primary repair versus redo-hypospadias with buccal graft. PROSPERO registration (CRD42021251423).
RESULTS
Five comparative studies with 576 cases (301 HBOT versus 275 controls) were included. Overall pooled effect estimates showed that the HBOT group has significantly lesser hypospadias repair failure (RR 0.52, 95%CI 0.37, 0.72). Subgroup analysis on the use of HBOT for graft take showed lesser graft failure compared to the control group (RR 0.20, 95% CI 0.05, 0.75), while the use of HBOT for primary and redo single staged hypospadias repair showed lesser complication rate (RR 0.56, 95%CI 0.40, 0.78). Based on ROBINS-I assessment, all included comparative studies are determined to be of serious risk of bias mainly due to presence of confounding.
CONCLUSION
The currently available low-quality of evidence suggests that compared to control groups, HBOT as an adjunctive intervention to complicated hypospadias repair was able to reduce surgical outcome failure and graft failure rates.

Penile squamous cell carcinoma (PSCC) is a rare but aggressive neoplasm with dual pathogenesis (human papillomavirus (HPV)-associated and HPV-independent). The development of targeted treatment is hindered by poor knowledge of the molecular landscape of PSCC. We performed a thorough review of genetic alterations of PSCC focused on somatic mutations and/or copy number alterations. A total of seven articles have been identified which, overall, include 268 PSCC. However, the series are heterogeneous regarding methodologies employed for DNA sequencing and HPV detection together with HPV prevalence, and include, in general, a limited number of cases, which results in markedly different findings. Reported top-ranked mutations involve , , , and . Numerical alterations involve gains in and , as well as amplifications in HPV integration loci. A few genes including , , and harbor both somatic mutations and copy number alterations. Notch, RTK-RAS and Hippo pathways are frequently deregulated. Nevertheless, the relevance of the identified alterations, their role in signaling pathways or their association with HPV status remain elusive. Combined targeting of different pathways might represent a valid therapeutic approach in PSCC. This work calls for large-scale sequencing studies with robust HPV testing to improve the genomic understanding of PSCC.
