Assessment of complications after laparoscopic surgery of kidney tumors using Clavien-Dindo classification

Abstract

Summary. Introduction Surgical procedures are accepted, basic method of treating kidney cancer. Objective of the work The aim of the study was to assess postoperative complications according to the Clavien-Dindo classification after laparoscopic procedures in the treatment of kidney cancer. Material and methods A retrospective study involved 112 patients. The research was based on the analysis of data from the medical records of the clinic and the documentation of the urological polyclinic. Classification of postoperative complications according to Clavien and Dindo in the operated patients were assessed on a 7-point scale. Results Less severe complications occurred in 24 patients (21.4%). All the above-mentioned complications were conservatively managed by the administration of drugs and blood transfusions. Grade IIIb complication occurred in one patient (0.9%) and required kidney removal. Conclusions The use of the Clavien - Dindo classification in the assessment of postoperative complications of laparoscopic renal procedures is a simple and objective diagnostic tool for the postoperative condition of patients. Discussion The assessment of postoperative complications is a generally accepted way to compare the results of surgical treatment, but it should be emphasized that the occurrence of intraoperative complications also affects the subsequent postoperative course of the operated person. For kidney surgery, there was no consensus on how to report it, resulting in a wide range of types and frequencies of complications reported. In addition, many different surgical techniques used in renal surgery and the continuous development of new ones require a standardized way of reporting complications to facilitate comparison. Criteria introduced by Clavien and Dindo surgeons have been used in everyday practice for many years as an objective method of accurate and comprehensive reporting of postoperative complications also after urological procedures
