Objectives The primary objective is to compare the imaging and surgical findings in a cohort of patients with suspected penile fracture (PF) Methods Retrospective cohort study of all patients with suspected PF over an 11-year period at a tertiary referral andrology centre. All dedicated presurgical imaging with ultrasound (US) and MRI was analysed...

Objectives To correlate imaging suggestive of penile fracture (PF) with intraoperative findings as the gold standard comparator in order to calculate the sensitivity and specificity. Methods Retrospective analysis (electronic and paper records) of all men referred for imaging querying penile fracture over ten years at a single centre (January 2010...

Introduction: Erectile dysfunction (ED) is associated with diabetes mellitus with an estimated prevalence of 52.5% in the diabetic population. The first-line therapy for ED are phosphodiesterase type 5 inhibitors (PDE5i), but data suggests that diabetic men may be less responsive than non-diabetic men. Thus, other treatments, including intracavern...

Introduction: Diabetes mellitus (DM) is a rapidly rising metabolic disorder with important systemic complications. Global figures have demonstrated the prevalence of DM has almost quadrupled from 108 million in 1980 to 422 million in 2014, with a current prevalence of over 525 million. Of the male sexual dysfunction resulting from DM, significant...

Diabetes is a rising global health concern and an increasingly common cause of male infertility. Although the definitive pathophysiological mechanisms underpinning the association between diabetes and infertility is unclear, there are several animal studies showing diabetes to be a detrimental factor on reproductive health through apoptosis, oxidat...

Use of testosterone replacement therapy (TRT) and anabolic-androgenic steroids (AAS) has increased over the last 20 years, coinciding with an increase in men presenting with infertility and hypogonadism. Both agents have a detrimental effect on spermatogenesis and pose a clinical challenge in the setting of hypogonadism and infertility. Adding to t...

Penile prosthesis surgery represents the end-stage treatment for erectile dysfunction. It is conventionally used only in cases of erectile dysfunction refractory to pharmacological treatments or vacuum constriction devices. Contemporary literature suggests that penile prothesis surgery is associated with a high satisfaction rate and a low complicat...

Background: Current evidence shows that cytoreductive nephrectomy (CN) could offer a survival benefit for patients with metastatic renal cell carcinoma (RCC). Nevertheless, due to a higher risk of perioperative complications this therapeutic strategy should be evaluated thoroughly. To identify perioperative mortality and morbidity predictors associ...

Introduction: Ureteral stricture (US) in the kidney transplant recipient is a rare complication that can lead to morbidity and graft loss. Risk factor recognition is crucial in the prevention and management of this entity. Delayed graft function (DGF), as defined by the need for dialysis in the first week after transplantation, has been proposed a...

ANTECEDENTES: La mayor parte de las lesiones testiculares se detectan en etapa temprana. En 10 a 20% de los casos pueden ser benignas. La biopsia por congelamiento ha demostrado ser confiable para evaluar lesiones testiculares. El diagnóstico de histología benigna puede evitar orquiectomías radicales innecesarias y sus complicaciones.OBJETIVO: Eval...

Background: Most testicular lesions are detected at the early stage and up to 10-20% of them are benign. Frozen section examination (FSE) has proven to be reliable for evaluating testicular lesions. The diagnosis of benign histology can prevent unnecessary radical orchiectomy and its complications. Objective: To evaluate the diagnostic accuracy of...

Conservative therapies, such as active surveillance, can be appropriate treatment for low-risk prostate cancer. The aim of this study was to analyze the frequency of Gleason score (GS) upgrading in patients with a low-grade GS. We reviewed our prospectively maintained database of patients with prostate cancer that underwent radical prostatectomy wi...

Background: Studies have shown that voiding symptoms do not correlate with a high postvoid residual volume. It is important to have clinical tools that help make early and effective decisions during the initial consultation. Objective: To assess the validity and degree of concordance between the sensation of incomplete voiding and high postvoid...

Algunos estudios han demostrado que los síntomas de vaciado no correlacionan con el residuo posmiccional elevado. Es importante contar con herramientas clínicas que permitan tomar decisiones prontas y efectivas en la primera consulta.

Antecedentes En el 2008 en México, el cáncer de próstata (CaP) ocupó el primer lugar como causa de muerte por neoplasias en hombres. Objetivo Describir las características clinicopatológicas y tratamientos de los casos incidentes de CaP. Material y métodos Análisis descriptivo de los casos hospitalarios nuevos de CaP del 2010 al 2014. Resultados Se...

Antecedentes La prostatectomía radical+linfadenectomía pélvica puede mejorar la supervivencia libre de progresión y supervivencia cáncer-específica en la enfermedad ganglionar. Objetivo Analizar las características de los pacientes con enfermedad ganglionar en el análisis histopatológico de la prostatectomía radical. Material y métodos Estudio retr...

To evaluate the role of PET and MRI fused image study inpatients with primary brain tumors previously treated, to determine the presence of radionecrosis vs residual tumor viability. Primary brain tumors were diagnosed by biopse and MR. 18FDG-PET scan and T1 enhanced MRI follow-up studies were performed between 3 and 5 months after treatment. The 1...
