INTRODUCTION At present, a second kidney transplant is considered an established therapeutic option for patients who have lost a previous graft. Second transplants show similar graft survival as first transplants. A debate exists about the benefit of submitting the patient to a third or fourth renal transplant, or to maintain dialysis. OBJECTIVE We sought(More)
BACKGROUND Natural orifice transluminal endoscopic surgery (NOTES) uses natural orifices to access the abdominal cavity. We adapted NOTES to perform transvaginal NOTES-assisted laparoscopic nephrectomy in living donors. OBJECTIVE To assess the feasibility and reproducibility of this procedure and compare it with conventional laparoscopic living donor(More)
Relationship between prostate cancer (PCa) and testosterone (T) is controversial. Conflicting evidence has been published about T levels and development of PCa. (1) To determine the relationship between hormone levels and the diagnosis of PCa. (2) To specifically focus on the relationship between PCa and T in men classified as biochemically hypogonadal.(More)
OBJECTIVE To study the ejaculatory mechanisms in men using a dynamic endorectal ultrasonographical approach. SUBJECTS AND METHODS Seven recordings were made of a young healthy volunteer during ejaculation, scanning the longitudinal plane from the bladder neck to the bulbous urethra. RESULTS The study demonstrated the existence of a pre-ejaculatory phase(More)
AIMS OF THE STUDY To evaluate the outcome of kidney transplantation in children with low weight. METHODS Retrospective review of the medical records of patients weighing 11 kg or less that received kidney transplantation between 2001 and 2013 were retrospectively reviewed. RESULTS Fifty-nine kidney transplantations were performed in pediatric patients(More)
OBJECTIVES To refine the clinical and radiologic description of an unusual benign disease, cystic pyeloureteritis (CPU), consisting of the appearance of suburothelial cysts that raise the mucosa layer of the urothelium. We also studied its relationship with various types of inflammation, including chronic infection, that may be the stimulus for the(More)
INTRODUCTION The evolution of renal antioxidant concentrations in the different phases of a non-heart-beating donor (NHBD) transplant after prolonged warm ischemia (40 and 90 minutes) and the effect of normothermic extracorporeal recirculation (37 degrees C) for 30 minutes were evaluated on antioxidant tissue concentrations in the kidney. METHODS Forty(More)
To evaluate the role of transrectal ultrasonography (TRUS) in the diagnosis of acute bacterial prostatitis (ABP) and to analyse the possible relationship between sonographic findings and clinical presentation and evolution, a prospective study using TRUS in patients with ABP was conducted. 45 patients (aged 58.2 +/- 14.6 y; mean +/- SD) with a clinical(More)
BACKGROUND A renal transplant is the treatment of choice for patients with end-stage renal disease due to its superior short- and long-term survival benefits compared with dialysis treatment. A common trend for kidney transplantation in developed countries is an increasing acceptance of older patients, patients with comorbidities, and patients with vascular(More)
The prevalence of human immunodeficience virus (HIV) infection among patients under renal replacement therapy varies, with estimates of 1% for Europe and 1.5% for the United States. Survival in HIV infected individuals receiving renal replacement therapy has improved since the introduction of high activity antiretroviral therapy (HAART). Current experience(More)
