When feasible from an oncologic standpoint, partial penectomy (PP) is often preferred to total penectomy (TP) for penile cancer treatment, for the preservation of functional urinary outcomes. However, to date, there has not been a direct comparison of perioperative outcomes between PP and TP. Comparing treatments for penile cancer has proven difficult due to the rarity of penile cancer in the United States. We aimed to report differences in pre-operative risk factors, intra-operative outcomes, and postoperative outcomes between TP and PP for penile cancer. Using the National Surgical Quality Improvement Program database, we conducted a retrospective cohort review of penile cancer patients enlisted in the database between the years 2006-2016 using the International Classification of Diseases clinical modification 9th revision codes. A total of 260 patients, 67 TP and 193 PP patients, were included. PP patients were less likely to be transferred patients (p = 0.002), diabetic (p = 0.026), and were more likely to have preoperative laboratory values within normal limits. PP patients also had shorter lengths of stay in the hospital (p < 0.001) and operating time (p < 0.001). Significant differences were also found for inpatient stay (p < 0.001), 30-day post-surgery complications (p < 0.001), deep incisional surgical site infection (SSI) (p = 0.017), wound disruption (p = 0.017), intraoperative or postoperative transfusion (p = 0.029), and sepsis (p < 0.005). Finally, PP patients required fewer concurrent surgical procedures (p < 0.001). Demographic differences between PP and TP patients may reflect patients presenting with more advanced oncologic disease. PP is associated with fewer postoperative complications, shorter surgeries, shorter hospital stays, fewer concurrent surgical procedures, and comorbid conditions compared to TP. A gap remains in the reported data pertaining to postoperative sexual function and erectile outcomes for PP at a national level.

INTRODUCTION AND IMPORTANCE
Urinary tract stones are a common disease, but concurrent large-size stones in the bladder and urethra are rare. This phenomenon can lead to obstruction, infection, and other complications. We reported the management of a rare case of a giant bladder stone accompanied by a big posterior urethral stone.
CASE PRESENTATION
A 36-year-old man with a chief complaint of not being able to have spontaneous micturition, frequent expulsion of stones from the penis, and a history of hematuria. Bladder examination revealed a giant bladder stone of 1278 Hounsfield Unit (HU) with a size of 4.1 × 7.2 cm, and urethral examination revealed a stone of 1275 Hounsfield Unit (HU) with a length of 4.3 × 4.2 cm, without mass. This patient underwent vesicolithotomy and urethrotomy. The evaluation showed spontaneous micturition and dissolved hydronephrosis.
CLINICAL DISCUSSION
Urinary tract stone management primarily involves endourology or open surgery. For smaller stones (<5-6 mm), medication is sufficient, as they often pass spontaneously. Larger stones may require interventions like vesicolithotomy or urethrotomy. Vesicolithotomy is preferred for complex or large bladder stones, while urethrotomy is performed if the stone location is palpable or seen on imaging. These procedures are practical options for general surgeons in first-level hospitals.
CONCLUSION
Concurrent large bladder and urethral stones are uncommon. Endourology or open surgery is typically employed. Treatment selection should be personalized to individual patient assessment to mitigate potential complications effectively.

Review
Human papillomavirus (HPV), a common cause of sexually transmitted diseases, may cause warts and lead to various types of cancers, which makes it important to understand the risk factors associated with it. HPV is the leading risk factor and plays a crucial role in the progression of cervical cancer. Viral oncoproteins E6 and E7 play a pivotal role in this process. Beyond cervical cancer, HPV-associated cancers of the mouth and throat are also increasing. HPV can also contribute to other malignancies like penile, vulvar, and vaginal cancers. Emerging evidence links HPV to these cancers. Research on the oncogenic effect of HPV is still ongoing and explorations of screening techniques, vaccination, immunotherapy and targeted therapeutics are all in progress. The present review offers valuable insight into the current understanding of the role of HPV in cancer and its potential implications for treatment and prevention in the future.

Hyperbaric oxygen treatment (HBOT) can be utilised for necrotising soft tissue infections, clostridial myonecrosis (gas gangrene), crush injuries, acute traumatic ischaemia, delayed wound healing, and compromised skin grafts. Our case was a 17-month-old male patient with Noonan syndrome, idiopathic thrombocytopenic purpura, and bilateral undescended testicles. Haematoma and oedema developed in the scrotum and penis the day after bilateral orchiopexy and circumcision. Ischaemic appearances were observed on the penile and scrotal skin on the second postoperative day. Enoxaparin sodium and fresh frozen plasma were started on the recommendation of haematology. Hyperbaric oxygen treatment was initiated considering the possibility of tissue necrosis. We observed rapid healing within five days. We present this case to emphasise that HBOT may be considered as an additional treatment option in patients with similar conditions. To our knowledge, no similar cases have been reported in the literature.

BACKGROUND & OBJECTIVE
Penile squamous cell carcinoma (SCC) is an extremely rare malignancy. It is usually caused by chronic human papillomavirus (HPV) 16 and HPV 18 infections. This study was conducted to investigate the immunohistochemical overexpression of p16, a surrogate marker for HPV, and to evaluate its usefulness as a potential diagnostic biomarker.
METHODS
In this cross-sectional prospective and retrospective cohort study, 56 penile squamous cell carcinoma (SCC) specimens and five penile premalignant specimens were evaluated in Kasturba Medical College, Mangalore, India, from January 2013- December 2018 in terms of clinical and histopathological features. Immunohistochemical expression for p16 in cases and controls was evaluated. Statistical comparison of p16 expression among clinical features, histological subtype, grade, and stages of tumor were done.
RESULTS
Analysis of the pattern of p16 staining showed diffuse and strong nuclear and cytoplasmic expression in 32.8% of the cases. There was a highly significant association (<0.001) of pattern of p16 expression among the HPV and non-HPV subtypes of penile carcinoma. p16 expression was not significantly associated with other prognostic parameters like site of the lesion, lymphovascular invasion, perineural invasion, histologic grade, and pathologic stage.
CONCLUSION
Expression of p16 would be a useful tool in differentiation between the HPV-associated and non-HPV-associated subtypes of penile SCC that may be helpful in prediction of aggressiveness and invasive potential of the respective histologic subtypes.

This multicentre retrospective study was conducted in 3 university hospitals in Egypt between April 2020 and June 2022. The aim was to assess the relation between Coronavirus Disease-19 (COVID-19) and ischemic priapism. Forty-three ischemic priapism patients were diagnosed and divided into two groups (30 in group I with ischemic priapism only, and 13 in group II with both ischemic priapism and COVID-19). Further sub-classification of COVID-19 patients according to the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection severity was done. Cavernosal aspiration was successful in 25 patients (83.3%) in group I and 12 (92.3%) in group II. Long term follow-up proved moderate to severe erectile dysfunction in 6 patients (20.0%) and 1 (7.7%) in group I and II, respectively. All those with severe erectile dysfunction were managed by distal shunt and prepared for penile prosthesis placement. The median duration of ischemic priapism was significantly longer in patients with severe erectile dysfunction [19 vs. 7 h, P = 0.01]. There was no statistically significant difference between both groups regarding patients' age (p = 0.8), required priapism management (p = 0.4), priapism recurrence (p = 0.1), and erectile dysfunction severity (p = 0.5). Ischemic priapism in COVID-19 patients can occur not only in severe, but also in mild or even asymptomatic cases. COVID-19 did not influence the ischemic priapism treatment protocol and post-treatment erectile function. COVID-19 and ischemic priapism seem to have a coincidence relation rather than a causal.

Comparative Study
Comparative evaluation of HPV genotyping: A study on the performance concordance between Anyplex II HPV28 detection and Linear Array genotyping tests in nationwide studies in Brazil.
BACKGROUND
Advances in laboratory techniques for HPV diagnosis necessitate a thorough assessment of the efficiency, replicability, sensitivity, and specificity of those methods. This study aims to validate and compare HPV detection/genotyping using the Anyplex™ II HPV28 Detection assay (Seegene) assay and the Linear Array HPV Genotyping test (Roche Diagnostics) on genital samples for use in epidemiological studies.
METHODS
From 6,388 penile and cervical DNA samples collected in the POP-Brazil, 1,745 were randomly selected to be included in this study. The samples were submitted to HPV detection and genotyping following the manufacturers' protocols. DNA was genotyped using the Anyplex™ II HPV28 Detection kit (Seegene), and the results were compared to those obtained using the Linear Array HPV Genotyping test (Roche Diagnostics). Concordance of HPV genotyping results was assessed by the percentage agreement and Cohen's kappa score (κ).
RESULTS
The agreement between the two methodologies was deemed good for HPV detection (κ = 0.78). Notably, Anyplex™ II HPV28 demonstrated enhanced capability in detecting a broader spectrum of genotypes compared to Linear Array.
CONCLUSION
Anyplex™ II HPV28 exhibited comparable results to the Linear Array assay in clinical specimens, showcasing its potential suitability for a diverse array of research applications requiring the detection and genotyping of HPV. The study supports the utility of Anyplex™ II HPV28 as an effective tool for HPV screening in epidemiological studies, emphasizing its robust performance in comparison to established diagnostic tests.

HSV infects keratinocytes in the epidermis of skin via nectin-1. We established a human foreskin explant infection model to investigate HSV entry and spread. HSV1 entry could only be achieved by the topical application of virus via high density microarray projections (HD-MAPs) to the epidermis, which penetrated beyond one third of its thickness, simulating in vivo microtrauma. Rapid lateral spread of HSV1 to a mean of 13 keratinocytes wide occurred after 24 hours and free virus particles were observed between keratinocytes, consistent with an intercellular route of spread. Nectin-1 staining was markedly decreased in foci of infection in the epidermis and in the human keratinocyte HaCaT cell line. Nectin-1 was redistributed, at the protein level, in adjacent uninfected cells surrounding infection, inducible by CCL3, IL-8 (or CXCL8), and possibly CXCL10 and IL-6, thus facilitating spread. These findings provide the first insights into HSV1 entry and spread in human inner foreskin in situ.

Review
Penile prosthesis implantation is an effective treatment for erectile dysfunction (ED) with high patient satisfaction and effectiveness. Unfortunately, infections remain a dreaded complication, often necessitating device removal and imposing a substantial healthcare cost. Biofilms are communities of microorganisms encased in a self-produced polymeric matrix that can attach to penile prostheses. Biofilms have been demonstrated on the majority of explanted prostheses for both infectious and non-infectious revisions and are prevalent even in asymptomatic patients. Biofilms play a role in microbial persistence and exhibit unique antibiotic resistance strategies that can lead to increased infection rates in revision surgery. Biofilms demonstrate physical barriers through the development of an extracellular polymeric substance (EPS) that hinders antibiotic penetrance and the bacteria within biofilms demonstrate reduced metabolic activity that weakens the efficacy of traditional antibiotics. Despite these challenges, new methods are being developed and investigated to prevent and treat biofilms. These treatments include surface modifications, biosurfactants, tissue plasminogen activator (tPA), and nitric oxide (NO) to prevent bacterial adhesion and biofilm formation. Additionally, novel antibiotic treatments are currently under investigation and include antimicrobial peptides (AMPs), bacteriophages, and refillable antibiotic coatings. This article reviews biofilm formation, the challenges that biofilms present to conventional antibiotics, current treatments, and experimental approaches for biofilm prevention and treatment.
