Introduction: the renal adenocarcinoma is considered as one of the more lethal neoplasias among urologic cancers. Objective: to characterize the patients treated due to renal adenocarcinoma emphasizing the diagnostic features, the treatment and the life prognosis. Methods: a descriptive study was conducted of patients cared due to renal adenocarcinoma from January, 1996 to December, 2005. Study variables included: age, sex, symptoms and signs, imaging studies, lesion size/tumor stage, therapeutical modalities used, complications derived from these and survival at 5 years of treatment. Results: in series of 94 patients there was predominance of 50-59 age group with 41 patients (43.6 %); the male sex was the more involved one with 66 cases (70.2 %) as well as the incidental diagnosis in 46 patients (48.9 %; ultrasound (US) was used in all the cases and it was positive in the 98.9 % and predominance of stage I lesions in 49 patients (52.1 %); the more used therapeutical modality was the surgery in 88 patients (93.6 %) including the lumbar route nephrectomy carried out in 59 patients (67.0 %). The 69.3 % of patients have not complications. The 5-years survival was of 97.9 %. Conclusions: the incidental diagnosis of renal adenocarcinoma is favored by the screening in risk groups, symptomatic or not, using the abdominal US. This is linked with a timely surgical treatment in early stages and the significant improvement of life prognosis.
