title: [Current patterns of presentation of renal tumors].
abstract: The aim of this paper is to describe the epidemiological characteristics, clinical management and pathologic patterns in a population with renal tumors 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 patients) 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 patients) were obese (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 patients (29.9%) there was more than one comorbidity; 18% had preoperative creatinine = 1.3 mg/dl. Lesions were = 4 cm (cT1a) in 45% of the patients, and 10.8% (86) had metastases at diagnosis. The lesions were resected in 93.5% and actively monitored in 6.5% (not resected). In surgery treated patients, 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 early disease stages. Nephron sparing surgery is the first choice in nearly half of patients. Active surveillance has been used in a greater percentage than previously reported.
