: Radical prostatectomy (RP) for prostate cancer treatment, although effective, can lead to severe erectile dysfunction. This study describes a new technique, which aims to reestablish the nerve stimulus in penile erection by two sural nerve graft bridges bilaterally, using the end to side neurorraphy. The first bridge is between femoral nerve and dorsal nerve of penis and the second, is between the femoral nerve and the interior of the corpus cavernosum. In this neurorraphy the endings of the newly formed fibres, generated by the femoral nerve, release acetylcholine inside the cavernous bodies, beginning the erection mechanism...

Periampullary carcinoma metastases are usually located at regional nodes, adjacent organs, liver or lung. On the other hand, metastatic penile cancer is uncommon. Penile metastasis usually originates from pelvic region with prostate and bladder being the most frequent primary location. We present a very rare case of periampullary carcinoma with penile metastasis in a 49-year-old man. He initially presented with early ampullary type periampullary carcinoma and had pyloric preserving pancreatoduodenectomy and adjuvant chemotherapy...

Erectile dysfunction (ED) associated with type 2 diabetes mellitus (T2DM) involves dysfunctional nitric oxide (NO) signaling and increased oxidative stress in the penis. However, the mechanisms of endothelial NO synthase (eNOS) and neuronal NO synthase (nNOS) dysregulation, and the sources of oxidative stress, are not well defined, particularly at the human level. The objective of this study was to define whether uncoupled eNOS and nNOS, and NADPH oxidase upregulation, contribute to the pathogenesis of ED in T2DM men...

Penile carcinoma (PC) is more frequent in underdeveloped countries, generally is diagnosed at an advanced stage when therapeutic options are restricted, and thus is associated with high morbidity/mortality rates. Recent studies have demonstrated clinical benefits with epidermal growth factor receptor (EGFR)-targeted therapy in PC patients, although there is no test that provides accurate patient selection. The aim of the present study was to evaluate the prognostic value of EGFR gene and protein status in tumor samples from patients with primary penile squamous cell carcinoma (SCC)...

AIMS: Prostate cancer is the most frequently diagnosed male cancer and urinary incontinence represents a major consequence following surgery. Penile compression clamps (PCCs) which externally occlude the urethra may be used to manage the incontinence. Despite potential complication of PCCs, such as deformation-inflicted tissue damage, to date, there are no reported biomechanical criteria for design of PCCs, in terms of quantitative parameters for evaluating the safety-versus-efficacy of existing or future designs...

BACKGROUND: Anogenital distance (AGD), the distance from the centre of the anus to the genitals, is a sexually dimorphic phenotype in mammals. Experimental studies have shown that AGD is a biomarker of prenatal androgen exposure during the masculinisation period of development. The aim of this study is to assess the relationship between anogenital distance (AGD), as an indirect marker of prenatal hormonal environment, and prostate cancer (PCa) severity. MATERIALS: We conducted a cross-sectional study with a total of 120 PCa patients with confirmed biopsy of the tumour from April 2007 to July 2015...

INTRODUCTION: Male genital degloving injuries are unusual and rarely caused by animal bite. Usually patients attend health care immediately if bitten in the genital area. Prophylactic antibiotics is routinely used (Gomes et al., 2000). A penile degloving usually begins just proximal of the coronal line and progress down to the base of the shaft. Deep erectile tissue and the spermatic cord are seldom damaged and the endogenous skin of glans usually survives (Brown and Fryer, 1957; Morey et al...

REVIEW
Juanita Crook
Squamous cell cancer of the penis is a radiocurable malignancy all too often managed solely by partial or total penectomy. Effective management of the primary tumor while preserving penile morphology and function is a priority. External radiotherapy and brachytherapy have a role to play in the definitive management of the primary tumor. Surgical nodal staging remains a cornerstone of management because it is the strongest predictor of survival, and inguinal status determines pelvic management. Postoperative radiotherapy of the regional nodes for high-risk pathology is indicated...

Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Exposure to HPV is very common, and an estimated 65%-100% of sexually active adults are exposed to HPV in their lifetime. The majority of HPV infections are asymptomatic, but there is a 10% chance that individuals will develop a persistent infection and have an increased risk of developing a carcinoma. The International Agency for Research on Cancer has found that the following cancer sites have a strong causal relationship with HPV: cervix uteri, penis, vulva, vagina, anus and oropharynx, including the base of the tongue and the tonsils...

Penile cancer is an uncommon malignancy. Squamous cell carcinoma constitutes approximately 95% of all histology. Non-squamous malignancies are rare in penis. Sarcomas of penis are rarer among them. Spindle cell sarcoma is one of the extremely rare sarcoma of penis. To best of our knowledge, only two cases have been reported so far, one in English literature and other in Japanese. We are presenting this uncommon case of spindle cell sarcoma of penis, which was diagnosed with microscopy with its characteristic immunohistochemistry...

Human Papillomaviruses (HPVs) are involved in the etiology of anogenital and head and neck cancers. The HPV DNA prevalence greatly differs by anatomical site. Indeed, the high rates of viral DNA prevalence in anal and cervical carcinomas contrast with the lower fraction of cancer cases attributable to HPVs in other anatomical sites, chiefly the vulva, the penis and head and neck. Here we analyzed 2635 Formalin Fixed Paraffin Embedded surgical samples that had previously tested negative for the presence of HPVs DNA using the SPF10/DEIA procedure, in order to identify the presence of other PVs not explicitly targeted by standard molecular epidemiologic approaches...

Carcinoma of the penis is a rare tumor in the United States and in western European countries. Clinical management has become more complex in recent years, because organ-preserving strategies are being favored. Furthermore, our understanding of the pathogenesis of this malignancy has grown considerably. As a result of these developments, the demands on the pathology reports of surgical specimens from the penis have increased. There are also some peculiarities with the current World Health Organization and TNM classification systems of penile cancer as compared with other tumor entities...
