Chronic orchialgia is a common urologic problem, however, determination of the etiology is often difficult and the pathophysiology is poorly understood. As a result, there is no clear algorithm for surgical treatment for men who have failed conservative medical treatment. This review aims to describe microsurgical denervation of the rat spermatic cord (SC) and summarize several surgical techniq...

PURPOSE We compared vasoepididymostomy to microsurgical epididymal sperm aspiration and intracytoplasmic sperm injection for treatment of epididymal obstruction secondary to vasectomy. MATERIALS AND METHODS Results in patients who underwent vasoepididymostomy for vasectomy reversal at our institution were compared to those reported previously for microsurgical epididymal sperm aspiration and ...

The introduction of the operative microscope for andrological surgery in the 1970s provided enhanced magnification and accuracy, unparalleled to any previous visual loop or magnification techniques. This technology revolutionized techniques for microsurgery in andrology. Today, we may be on the verge of a second such revolution by the incorporation of robotic assisted platforms for microsurgery...

OBJECTIVE To investigate whether a newly designed nonabsorbable polymeric stent for the reconstruction of the vas deferens provided less stricturing at the site of the anastomosis in comparison with the conventional microsurgical reconstruction of the vas deferens. DESIGN Prospective randomized study in 26 rabbits, comparing the one-layer microscopic sutured procedure with a biocompatible ste...

The prevalence of varicocele is 7% and 10–25% in pre pubertal and post pubertal males, respectively [1]. Varicoceles are found in 21–41% of men with primary infertility and 75–81% of those with secondary infertility. Physical examination of varicocele has a sensitivity and specificity of around 70%. The Color Doppler ultrasound (7MHz) has sensitivity of 50% and specificity of 90%. A pencil prob...

Only a small minority of women who are protected by contraceptive sterilization express regret about that method choice, regardless of whether they or their husbands have had the surgery, according to findings from a prospective, multicenter study.1 Within five years after their husbands’ vasectomy, 6% of women indicated that it was not a good choice; essentially the same proportion of steriliz...

INTRODUCTION Vasectomy is a common method of sterilisation. However, it is less popular than tubal ligation world-wide. It is also a frequent cause of litigation relating to its complications. This article reviews the early and late risks associated with the procedure. PATIENTS AND METHODS Data collection was done using the internet to search Medline for obtaining evidence-based medicine revi...

The aim of the present review is to summarize recent developments in the field of urologic robotic surgery. A nonsystematic literature review was performed to retrieve publications related to robotic surgery in urology and evidence-based critical analysis was conducted by focusing on the literature of the past 5 years. The use of the da Vinci Surgical System, a robotic surgical system, has been...

Decision on which is the best treatment for a problem that has more than one way to be dealt with goes much further from exclusively looking to the final results. Decision must include which are the final results you are looking for, how many variables are present in both options, money expenditure to reach the result and finally, how much resources are available for it. The beginning of 90’s b...

The mammalian epididymis is a fundamental organ for sperm cell maturation; it allows mammals to acquire their fertilizing ability. We have previously shown that during obstruction in cases of vasectomy, gene expression profiles were modified in human and cynomolgus monkey epididymides. Paracrine factors thus appear to be key elements in local gene expression along the epididymis. Local renin-an...
