Objective: To retrospectively evaluate the efficacy and safety of percutaneous radiofrequency ablation (RFA) done to treat renal tumors in patients with high surgical risk or with the risk of developing multiple renal tumors in the medium term at our center over a period of 10 years., Material and Methods: Between 2005 and 2015, we used RFA to treat 89 T1a or T1b tumors in 87 patients (mean age, 73.7±10.87 years) with high surgical risk. We excluded patients treated with radiofrequency and embolization or microwave ablation. The tumors treated were clear cell carcinomas (43.6%), papillary renal carcinomas (17.2%), chromophobe renal cell carcinomas (10.3%), cystic tumors (2.2%), and an angiomyolipoma (1.1%). The mean size of the tumors was 2.6cm. Computed tomography and/or ultrasonography were used to guide the procedure. We analyzed the relation between the efficacy of the procedure and patients' age, the type of needle, the source of the patients, the size and location of the tumor, and the number of sessions required to achieve ablation. We recorded all complications., Results: The RFA procedure was completed in all patients. The mean follow-up period was 32.1 months. The efficacy was 93.7%. A single session was sufficient in 87.5% of patients; 8% required two sessions and 4.5% required three sessions. The only factor associated with worse efficacy was the size of the tumor (p=0.03). The rate of complications was 5.6%., Conclusions: RFA is efficacious and safe, with results comparable to those reported in the literature., (Copyright © 2016 SERAM.

Life-threatening hemoptysis is a severe condition that requires rapid diagnosis and treatment. One of the treatments of choice is embolization. The initial assessment aims to locate the origin and cause of bleeding. The technological advance of the development of multidetector computed tomography (MDCT) has changed the management of patients with life-threatening hemoptysis. MDCT angiography makes it possible to evaluate the cause of bleeding and locate the vessels involved both rapidly and noninvasively; it is particularly useful for detecting ectopic bronchial arteries, nonbronchial systemic arteries, and pulmonary pseudoaneurysms. Performing MDCT angiography systematically before embolization enables better treatment planning. In this article, we review the pathophysiology and causes of life-threatening hemoptysis (including cryptogenic hemoptysis) and the MDCT angiography technique, and we review how to systematically evaluate the images (lung parenchyma, airways, and vascular structures)., (Copyright © 2013 SERAM.

New Spanish Law of Medical Specialties has come to correct the limitations of previous regulations regarding the figure and the functions of the Tutor. However, it continues lacking a description of the role of the residents in their training. Resident's Statute and Specialty Program add some information. Regulations establish that the residents are not passive actors in their training. As well as their labor obligations, including exclusivity and observance of the rules of the institutions in which they are working, the residents have the obligation of training themselves and of progressively taking on responsibilities relative to the specialty. This includes non-assistential training also, medical sessions preparation, attendance to committees and use of new technologies and on-line resources. Moreover, following Resident's Statute, the residents are full members of the Radiology department, sharing its goals and those of the institution in which it is included, and helping in its achievement. And they are committed also to achieve the goals of their training program and to have an active attitude in the training process. A resident is as important to the result of the training process as the members of the staff., (Copyright © 2010 SERAM. Published by Elsevier Espana. All rights reserved.)
