title: [Incidental diagnosis of renal carcinoma. Impact on prognosis and survival].
abstract: A retrospective study was conducted in 206 renal carcinomas (RC) that underwent surgery between 1983 and 1992, evaluating those that were diagnosed incidentally. Among this series, 74 cases (35.9%) were incidental renal carcinomas (IRC). The complementary examination that allowed to reach a diagnosis was ultrasound in 58 (78.4%) patients, computerized axial tomography (CT) in 23 (17.6%) and intravenous urography (IVU) in 3 (4%). An evaluation is made of the main prognostic factors (nuclear differentiation grade and pathological stage) and the survival in these patients. The results obtained allow to conclude that IRC display an earlier pathological stage and lower nuclear differentiation grade than the other RC, the difference being statistically significant (p < 0.05). Also, the probability of survival in IRC-diagnosed patients is higher than in those diagnosed with non-incidental RC, the difference being statistically significant (p < 0.05).
