ABSTRACT

Introduction: the diagnosis of renal masses has migrated from the stage in which the patient presents symptoms to the incidental stage, where they are detected by imaging studies. Objective: to determine the behavior of the incidental diagnosis of renal masses in the National Center for Minimal Access Surgery. Method: an observational, analytical and cross-sectional study was carried out in a series of 120 patients with a diagnosis of renal masses operated by laparoscopic surgery, at the National Center for Minimal Access Surgery, in the period from January 2014 to May 2019. They considered perioperative and oncological variables. Absolute, relative, mean and standard deviation frequencies were found; Pearson's chi-square test was used to associate the variables with a significance of 95 %, p <0.05. Results: incidental diagnosis predominated (64.2 %). The mean age and tumor size were 58.2 years and 4.24 cm, respectively. Malignant tumors predominated, in tumor stage pT1a and masses of moderate surgical complexity. Incidental diagnosis was not statistically associated with increasing age (p = 0.0585), nor with benign or malignant histology (p = 0.9787). Most of the patients who received partial nephrectomy were diagnosed incidentally (p = 0.0077). The tumor stage pT1a was significantly associated (p = 0.0157) with the incidental diagnosis of renal masses. Conclusions: the incidental diagnosis of renal masses predominated over the presence of symptoms and was significantly associated with low tumor stage and partial nephrectomy, but not with increasing age and tumor histology.
