Introduction: With the advanced laparoscopic and robotic surgery, thromboembolic prophylaxis in urologic procedures has traditionally been based on the experience of other surgical specialties. This paper aims to analyze the current recommendations, through a detailed study of the European clinical guidelines and bibliography, applying the recommendations of thromboprophylaxis to the daily urological practice., Objectives: To elaborate general recommendations to surgical patients in Urology, avoiding the risk of perioperative thromboembolic events. Optimize medication in chronic patients and accurately classify who are eligible for bridge therapy., Material and Methods: A review of the available literature and the European clinical guidelines was carried out. We analyzed the most recent consensus articles by studying the available bibliography, trials and reviews on which the European guidelines for thromboprophylaxis in urology are based., Results: Thromboembolic prophylaxis should be targeted towards surgeries that require abdominal approaches, prolonged bed rest or oncological pathologies. Bridge therapies with low molecular weight heparins should be limited. Patients undergoing treatment for chronic conditions can benefit from bridge therapies in specific cases., Conclusions: According to the current guidelines, there might be an overuse of heparins in the daily clinical practice. The development of -direct oral- anticoagulants have shown to reduce the time to reintroduction of medication for chronic conditions as well as a more effective bleeding management., (Copyright © 2019 AEU.

Introduction: Posterior urethral stenoses and contractures are complications after treatment of benign prostatic hyperplasia (BPH), localised prostate cancer (PCa), and orthotopic neobladder formation, compromising prognosis and functional outcomes., Objectives: To identify factors related to aetiology, prevention and treatment of non-traumatic posterior urethral stenosis and contractures., Acquisition of Evidence: Review of the published evidence related to posterior urethral stenosis and contractures after PCa treatment, BPH therapies and orthotopic neobladder formation. PubMed database search with English and Spanish papers considered. Cohort studies, case series, prospective and retrospective studies and review papers were included., Synthesis of Evidence: Posterior urethral stenoses and contractures are common, leading to significant morbidity. A worsening on voiding quality should rise some concerns. Careful surgical and/or radiotherapic techniques prevent their development. Endoscopic therapies are the initial approach, with complex urethroplasties often required. Subsequent urinary incontinence, the most important sequelae, may need artificial sphincters., Conclusions: Non-traumatic posterior urethral stenoses could be important complications, potentially compromising the outcomes of initial therapy. They could require complex surgeries leading to urinary incontinence., (Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.)

Introduction: Clavien-Dindo classification system has been proposed to grade perioperative complications in percutaneous nephrolithotomy. The complications of this technique that have taken place in the last 2 years are reported in this paper according Clavien-Dindo classification., Materials and Methods: Between 2011 and 2012 a total of 255 percutaneous nephrolithotomy were performed at our center for stones more than 2 cm in size. In order to determine the incidence of complications classified in the modified Clavien-Dindo system, statistical analysis of the data obtained was carried out., Results: During the period analyzed, 255 percutaneous nephrolithotomy were performed in 249 patients, 41% of the right side, 57% of the left side and 2% bilateral and simultaneous. 137 and 112 patients were males and females, respectively. The most prevalent comorbidities were: hypertension (AHT) in 101 patients (40.6%), BMI>30 in 81 patients (32%), diabetes mellitus in 46 patients (18.5%) and coagulation abnormalities in 24 patients (9.6%). A total of 70 cases (27.4%) were distributed according to Clavien-Dindo classification: grade i, 8.4%, grade ii 8.4%, grade iiia 4.4%, grade iiib 6% grade iva .8%, grade ivb: 0% and grade v 0%., Conclusions: A graded classification scheme for reporting the complications of percutaneous nephrolithotomy is useful for monitoring and reporting outcomes. We propose a standardized use of this classification in order to make the results comparable among different centers performing the technique., (Copyright © 2014 AEU.
