OBJECTIVES: To study the prevalence and risk factors of the lumbar eventration after lumbotomy in the flank. MATERIAL AND METHODS: Survey of 230 patients that underwent lumbotomy in the flank, with a least followup of two years. Statistical study: contingency 2 x 2 tables (Pearson's chi 2 or Fisher exact test) to compare qualitative variables, Student's test to compare quantitative variables, Kaplan-Meier test and comparison of Log-rank curves. For the study of clinical variables with more influence in postoperative lumbar eventration, a logistic regression model was used. RESULTS: The prevalence of postoperative lumbar eventration was 31.3%. Clinical variables more influence for postoperative lumbar eventration are: age, deficit of proteins, wound infection and haematoma of the abdominal wall. CONCLUSIONS: Eventration is one the most frequent complications in urologic surgery and is of primary importance due to its laboral, economic and social implications.
