PURPOSES
Penile fracture (PF) with associated urethral injury has been described as a rare condition yet a serious urological emergency. We conducted this systematic review to address the current literature concerning the etiology, presentations, intra-operative findings, site of injury, and complications of PF with associated urethral injury, Materials and Methods: The present systematic review was limited to human-based studies published in English language, and reporting clinical data on PF cases with associated urethral injuries. A comprehensive search of the literature was conducted on five electronic databases from their inception to May 2022: Medline via PubMed, Web of Science, Google Scholar, Scopus, and EBSCO host.
RESULTS
A total of 15 studies were included encompassing 1671 patients with PF. Out of 1665 patients with PF retrieved from the case series studies, 65 patients had associated urethral injuries giving a point prevalence of 3.9%. The vast majority of the patients had blood on the meatus and hematuria suggestive of urethral injury (57/59; 96.6%). Forty patients had partial urethral disruption and the rest of the patients had a complete rupture. All patients received primary urethroplasty as the main modality of treatment. The median hospital stay was two days and the median duration of transurethral catheterization was 21 days. Five patients (8.5%) developed urethral stricture; other complications included penile curvature (6.7%), palpable fibrosis (6.7%), and erectile dysfunction (3.4%).
CONCLUSIONS
Urethral injuries are uncommon, but serious findings, in patients with PF. Primary urethroplasty appears to achieve satisfactory outcomes with a low incidence of short and long-term complications.

With the onset of a metabolic syndrome epidemic and the increasing life expectancy, erectile dysfunction (ED) has become a more common condition. As incidence and prevalence increase, the medical field is focused on providing more appropriate therapies. It is common knowledge that ED is a chronic condition that is also associated with a myriad of other disorders. Conditions such as aging, diabetes mellitus, hypertension, obesity, prostatic hypertrophy, and prostate cancer, among others, have a direct implication on the onset and progression of ED. Characterization and recognition of risk factors may help clinicians recognize and properly treat patients suffering from ED. One of the most reliable treatments for ED is penile prosthetic surgery. Since the introduction of the penile prosthesis (PP) in the early seventies, this surgical procedure has improved the lives of thousands of men, with reliable and satisfactory results. The aim of this review article is to characterize the epidemiology of men undergoing penile prosthetic surgery, with a discussion about the most common conditions involved in the development of ED, and that ultimately drive patients into electing to undergo PP placement.

Review
PURPOSE
Squamous cell carcinoma (SCC) of the penis is a rare disease in developed countries but is associated with significant morbidity and mortality. A crucial prognostic factor is the presence of inguinal lymph node metastases (ILNM) at the time of diagnosis. At least 25% of cases have micrometastases at the time of diagnosis. Therefore, we performed a literature review of studies evaluating factors, both clinical and pathological, predictive of lymph node metastases in penile SCC.
MATERIALS AND METHODS
Studies were identified using PubMed and search terms included the following: penile cancer, penile tumor, penile neoplasm, penile squamous cell carcinoma, inguinal lymph node metastasis, lymph node metastases, nodal metastasis, inguinal node metastasis, inguinal lymph node involvement, predictors, and predictive factor. The number of patients and predictive factors were identified for each study based on OR, HR, or RR in multivariate analyses, as well as their respective significance values. These were compiled to generate a single body of evidence supportive of factors predictive of ILNM in penile SCC.
RESULTS
We identified 31 studies, both original articles and meta-analyses, which identified factors predictive of metastases in penile SCC. The following clinical factors were predictive of ILNM in penile SCC: lymphovascular invasion (LVI), increased grade, increased stage (both clinical and pathological), infiltrative and reticular invasion, increased depth of invasion, perineural invasion, and younger patient age at diagnosis. Biochemically, overexpression of p53, SOD2, Ki-67, and ID1 were associated with spread of SCC to inguinal lymph nodes. Diffuse PD-L1 expression, increased SCC-Ag expression, increased NLR, and CRP >20 were also associated with increased ILNM.
CONCLUSIONS
A multitude of factors are associated with metastasis of SCC of the penis to inguinal lymph nodes, which is associated with poor clinical outcomes. The above factors, most strongly LVI, grade, and node positivity, may be considered when constructing a nomogram to risk-stratify patients and determine eligibility for prophylactic inguinal lymphadenectomy.

INTRODUCTION
Fibrosis is characterized by dysregulation and accumulation of extracellular matrix. Peyronie's disease and Dupuytren disease are fibroproliferative disorders of the tunica albuginea of the penis and fascia of the hand, respectively. Chronic hyperglycaemia due to diabetes mellitus can also lead to tissue injury and fibrosis. A meta-analysis has shown a relationship between Dupuytren disease and diabetes (overall odds ratio, 3.1; 95% confidence interval, 2.7-3.5). This review explores commonalities in the pathogenesis of Peyronie's disease, Dupuytren disease and diabetes.
METHODS
A search of the PubMed database was conducted using the search terms "diabetes" AND "Peyronie's disease"; and "diabetes" AND "Dupuytren."
RESULTS
Genome-wide association and gene expression studies conducted with tissue from people with Peyronie's disease or Dupuytren disease identified signalling pathways associated with wingless-type mammary-tumour virus integration site signalling, extracellular matrix modulation and inflammation. Biochemical studies confirmed the importance of these pathways in the pathogenesis of fibrosis with Peyronie's disease and Dupuytren disease. Dysregulation of matrix metalloproteinase activity associated with extracellular matrix breakdown was implicated in fibroproliferative complications of diabetes and in the aetiology of Peyronie's disease and Dupuytren disease. A notable percentage of people with diabetes have comorbid Peyronie's disease and/or Dupuytren disease.
CONCLUSIONS
Studies have not been performed to identify fibroproliferative pathways that all 3 conditions might have in common, but data suggest that common pathways are involved in the fibroproliferative processes of Peyronie's disease, Dupuytren disease, and diabetes.

Meta-Analysis
PURPOSE
False penile fractures (FPF) represent a rare sexual emergency characterized by blunt trauma of penis in the absence of albuginea's injury, with or without lesion of dorsal penile vein. Their presentation is often indistinguishable from true penile fractures (TPF). This overlapping of clinical presentation, and lack of knowledge about FPF, can lead surgeons often to proceed directly to surgical exploration without further examinations. The aim of this study was to define a typical presentation of false penile fractures (FPF) emergency, identifying in absence of "snap" sound, slow detumescence, penile shaft ecchymosis, and penile deviation main clinical signs.
METHODS
We performed a systematic review and meta-analysis based on Medline, Scopus and Cochrane following a protocol designed a priori, to define sensitivity of "snap" sound absence, slow detumescence and penile deviation.
RESULTS
Based on the literature search of 93 articles, 15 were included (73 patients). All patients referred pain, most of them during coitus (n = 57; 78%). Detumescence occurred in 37/73 (51%), and all patients described detumescence occurrence as "slow". The results show that single anamnestic item have a high-moderate sensibility in the diagnosis of FPF, and the highest sensitive item was penile deviation (sensibility = 0.86). However, when more than one item is present, overall sensitivity increases greatly, closing to 100% (95% Confidence Interval 92-100).
CONCLUSION
Surgeons can consciously decide between additional exams, a conservative approach, and rapid intervention using these indicators to detect FPF. Our findings identified symptoms with excellent specificity for FPF diagnosis, giving clinicians more useful tools for making decisions.

Review
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.
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: 15 September 2017.Date of most recent search of trial registries and of Embase: 12 December 2016.
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 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 but all three trials reported on the reduction in frequency of stuttering priapism, our second primary outcome. No significant effect of any of the treatments was seen compared to placebo. Immediate side effects were not found to be significantly different from placebo in the two trials where this information was reported. We considered the quality of evidence to be low to very low as all of the trials were at risk of bias and all had low participant numbers.
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.

Review
Risk and benefits of penile length preservation techniques during penile prosthesis implantation: a systematic review by the young academic urologists sexual and reproductive health working group.
BACKGROUND
Penile shortening, frequently resulting from end-stage Peyronie's disease (PD), has a negative impact on patients' sexual activity and overall quality of life, especially when accompanied by Erectile dysfunction (ED). Various surgical techniques have been described to manage concomitant ED and penile shortening through penile prosthesis (PP) implantation.
OBJECTIVES
To evaluate the benefits and risks of different penile length preservation techniques during PP implantation.
DESIGN
A systematic review of the available literature on the use of penile length preservation maneuvers in conjunction with PP implantation was conducted.
DATA SOURCES AND METHODS
For this systematic review, three databases (Medline, Embase and Cochrane) and clinical trial.gov were queried for relevant publications from 1 January 1990 to 1 September 2022. The review process followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.
RESULTS
The qualitative analysis included 15 relevant articles involving 1186 adult patients who underwent penile length preservation techniques during PP implantation. Penile lengthening of 1-7 cm was reported. Overall, postoperative complications were described in up to 21.7% of cases. Only five studies reported functional outcomes, showing a significant improvement in postoperative period based on the administered questionnaire (e.g. IIEF - International Index of Erectile Function, EDITS - Erectile Dysfunction Inventory of Treatment Satisfaction).
CONCLUSION
Penile length preservation procedures appear to offer a viable option for managing acquired penile shortening, particularly in cases of PD. However, they are associated with a significant risk of complications. Proper patient selection, thorough discussion of risks and benefits, and referral to high-volume centers are mandatory to achieve optimal outcomes and minimizing complications.

Review
INTRODUCTION
The management options for regional lymph nodes (LNs) in men with penile cancer include surveillance, surgery, and chemotherapy. The use of radiotherapy (RT) for nodal disease follows tradition and single-institution policies. We aimed to analyse the existing evidence regarding the management of penile cancer patients with suspected or known metastatic pelvic LNs using pelvic LN dissection (PLND) with RT versus PLND or RT alone.
METHODS
A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, with no filters for language or time. The search was conducted in EMBASE, MEDLINE/PubMed, and Cochrane Library. Inclusion criteria were adult men with penile cancer and suspected metastatic pelvic LNs, undergoing PLND with or without RT or RT alone. Primary outcomes included disease-specific survival and locoregional recurrence. Secondary outcomes included overall survival and complications of therapy.
RESULTS
A total of 552 articles were identified. Only eight retrospective studies were eligible for inclusion (including 406 patients). All studies had a high risk of bias. None of the studies reported the use of neoadjuvant RT. Indications for PLND varied but were usually two or more clinically positive inguinal nodes with or without extracapsular extension. Adjuvant RT was mainly used in positive pelvic LNs or pN2/pN3 stages. The rate of locoregional recurrence following adjuvant RT was 70%. Complications of treatment were reported in two studies only.
CONCLUSIONS
There is insufficient evidence to recommend the use of adjuvant RT following PLND in penile cancer patients. The quality of evidence is low due to the retrospective design and high risk of bias. Randomized clinical trials are required to assess the efficacy and safety of adjuvant RT and PLND.

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
PURPOSE
We wanted to assess the safety and efficacy of nontherapeutic male circumcision through a systematic review of the literature.
METHODS
We systematically searched The York Centre for Reviews and Disseminations, Cochrane Library, PubMed, and EMBASE databases for randomized controlled trials published between January 1997 and August 2008. Studies reporting on circumcision in an operative setting in males of any age with no contraindications to or medical indications for circumcision were eligible for inclusion. The main comparator was intact genitalia. From 73 retrieved studies, 8 randomized controlled trials were ultimately included for analysis.
RESULTS
Severe complications were uncommon. Analgesia/anesthesia during circumcision was promoted. The prevalence of self-reported genital ulcers was significantly lower in circumcised men than uncircumcised men (3.1% vs 5.8%; prevalence risk ratio 0.53; 95% confidence interval [CI], 0.43-0.64; P<.001). Circumcised sub-Saharan African men were at significantly lower risk of acquiring human immunodeficiency virus/acquired immune deficiency syndrome than were uncircumcised men (random effects odds ratio = 0.44, 95% CI, 0.32-0.59; P <.001). The evidence suggests that adult circumcision does not affect sexual satisfaction and function.
CONCLUSIONS
Strong evidence suggests circumcision can prevent human immunodeficiency virus/acquired immune deficiency syndrome acquisition in sub-Saharan African men. These findings remain uncertain in men residing in other countries. The role of adult nontherapeutic male circumcision in preventing sexually transmitted infections, urinary tract infections, and penile cancer remains unclear. Current evidence fails to recommend widespread neonatal circumcision for these purposes.
