UNASSIGNED: The aim of this paper is to describe the epidemiological characteristics, clinical management and pathologic patterns in a population with @entity703 in our institution. Prospective data collection was performed over a period of 4.5 years, from January 2010 to June 2014. A total of 819 cases (796 @entity1 ) were treated for renal mass during this period. The mean age was 60.7 years (SD 13.1). There were 553 (69.5%) males (male to female ratio: 2.2: 1). Twenty nine per cent (230 @entity1 ) were @entity28 (BMI = 30). The diagnosis was incidental in 653 cases (79.7%), 48.8% presented one or more risk factors, being smoking the most frequent (34%). In 238 @entity1 (29.9%) there was more than one comorbidity; 18% had preoperative @entity1011 = 1.3 mg/dl. Lesions were = 4 cm (cT1a) in 45% of the @entity1 , and 10.8% (86) had @entity3 at diagnosis. The lesions were resected in 93.5% and actively monitored in 6.5% (not resected). In surgery treated @entity1 , radical nephrectomy was performed in 51.5% of cases, and nephron sparing surgery in 48.5% of them. The laparoscopic approach was used in 56.2%. The pattern of presentation of renal masses is characterized by incidental diagnosis in @entity66 stages. Nephron sparing surgery is the first choice in nearly half of @entity1 . Active surveillance has been used in a greater percentage than previously reported.
