Although a rare occurrence, this event may occur as a result of self-mutilation among individuals with psychiatric disturbances or due to work-related accidents, iatrogenic injuries or the actions of individuals motivated by jealously, rage and feelings of betrayal. In western societies, most penile amputations are the result of self-aggression during a psychotic episode, the treatment of victims involves resuscitation, stabilization and immediate psychiatric support. The amputated tissue must be preserved under hypothermic conditions. Micro-surgery is currently the most widely employed method for penile replantation. This paper describes a successful case of penile replantation following 5 hours of warm ischemia.
Primary urethral carcinoma is much more common in women than in men due to its association with urethritis. A 65-year-old man presented with a 10-month history of penile induration, obstructive voiding symptoms and hematuria. Urethrocystoscopy showed a solitary mass in the proximal urethra and no bladder involvement. It was performed penectomy without bladder neck excision and regional staging lymphadenectomy of the obturator lymph nodes. Pathological diagnosis revealed adenosquamous cell carcinoma with squamous and glandular components. We described a case of primary mixed glandular-endocrine tumor of the male proximal urethra consisting of adenosquamous cell carcinoma with squamous and neuroendocrine components.
The aim of this study was to investigate the effect of the anti-inflammatory and anti-fibrotic actions of ANX1 on erectile function (EF). Forty-eight male Wistar rats were randomly distributed into four equal groups: one group (sham operation-control) and three groups (bilateral cavernous nerve (CN) crush injury). Crush injury groups were treated prior to injury with an intravascular injection of either ANX1 (50 or 100 μg kg) or vehicle. EF was assessed by CN electrical stimulation at 2 and 7 days after CN injury with histomorphometric and immunohistochemical analysis. ANX1 demonstrated functional preservation as the increase in intracavernous pressure (ICP). A dose-response relationship regarding the effect on penile tissue was confirmed, and preservation of the penile dorsal nerves and anti-apoptotic effects in the corpus cavernosum (real P-value vs injured control). ANX1 treatment prevented collagen deposition and smooth muscle loss in the penis. ANX1 normalized the expression of vascular endothelial growth factor and decreased tumor necrosis factor-α in the lumen of the blood vessels of the organ. ANX1 proved effective in preserving EF in a rat model of neurogenic erectile dysfunction. ANX1 treatment before CN injury in rats improved erectile recovery, enhanced vascular regeneration and preserved the micro-architecture of the corpus cavernosum. The clinical availability of this compound merits application in penile rehabilitation studies following radical prostatectomy.
BackgroundRisk factors may influence the improvement or worsening of erectile dysfunction (ED). The aim of the current study was to evaluate the effect of systemic hypertension on ED in patients with peripheral arterial disease.MethodsThe effect of hypertension on ED was assessed in 125 consecutive patients in a cross-sectional quantitative study. The ages of the patients ranged from 19 to 88 years old (mean: 59.82 ± 10.48 years). The only exclusion criterion was the amputation of one or both legs. The ankle-arm index was assessed and the international index of ED questionnaire was applied to all participants in the study.ResultsOf the 125 patients, 22 (17.6%) had mild (grade 1), 50 (40.0%) had moderate (grade 2) and 53 (42.4%) had severe (grade 3) ED. Hypertensive patients have more ED, with ED in hypertensive patients being associated to chronic arterial disease. However, in comparison with normotensive patients, hypertension exerts an immediate protective effect on erectile function.ConclusionsIn conclusion, although erectile function is initially protected by systemic arterial hypertension in patients with chronic arterial disease, both chronic arterial disease and ED deteriorate over the long term in hypertensive patients.
BackgroundThe rapid dissemination of the coronavirus 2019 (COVID-19) had dramatic effects on individuals and healthcare systems in 2020. At our tertiary hospital, surgeries were recommended for patients at high oncological risk, with the prioritization of the maintenance of care and treatment of cancer. We aimed to assess the impact of the pandemic on the diagnosis and treatment of patients with urological tumors under the care of a university hospital.
Materials and methodsA retrospective analysis was performed of the charts of patients with urological tumors (prostate, kidney, bladder, and testicle) under the care and treated surgically at the Hospital de Base in 2019 and 2020, independently of ethnicity. The results were compared by the chi-square test (with a significance level of 5%).
ResultsA discrete increase occurred in the quantity of appointments in 2020 (n = 5,846) compared to 2019 (n = 5,726). The most frequent types of cancer in 2019 and 2020 were, respectively, prostate (70.97% and 73.37%), bladder (18.07% and 12.52%), kidney (7.96% and 8%), and testicle (29.24% and 70.76%). Analyzing 279 surgeries performed on patients with prostate tumors, a 12.7% increase occurred in the year of the pandemic. Analyzing 271 surgical procedures on patients with bladder cancer, no considerable change occurred.
ConclusionThe analysis of the impact of the pandemic on the diagnosis and treatment of patients with urological tumors at a university hospital revealed a discrete increase in the number of outpatient appointments and a slight reduction in the number of patients and surgical procedures in the year of the pandemic (2020). More surgical procedures were conducted on patients with prostate cancer in 2020. More patients with bladder cancer sought medical care in the year of the pandemic, and practically the same quantity was submitted for surgical treatment. There was no statistically significant difference among types of cancer.
Genital lymphedema in men can affect the penis and/or scrotum, causing deformity and causing sexual limitations, social isolation, poor quality of life and recurrent subcutaneous infections due to difficulties in hygiene. There are few studies in the literature emphasizing the treatment of penile fibrosis after penoscrotal lymphedema. The purpose of this report is to describe a case of penile fibrosis treated using a new compression method.
