Abstract: Objective To evaluate the learning curve of goal-oriented retroperitoneoscopic adrenal lesion resection measured by operative length and intraoperative blood loss. Methods The clinical data of 60 patients underwent Goal-oriented retroperitoneoscopic adrenal lesion resection completed by the same group of surgeons from January 2019 to January 2021 were retrospectively analyzed. All the cases were divided into group A（case 1 to 15）, group B （case 16 to 30）, group C（case 31 to 45）, group D （case 46 to 60）. Operative length, intraoperative blood loss, incision length and postoperative hospital stay were analyzed and differences between groups were compared. Results By the statistical analysis, the operative length and intraoperative blood loss was decreasing with the increase of cases. By multiple comparison,differences of the operative length and intraoperative blood loss between group A and group B, C, D were significant （P<; 0.05）. Differences of the operative length and intraoperative blood loss between group B and group C, D were significant （P<; 0.05）. There was no significant difference differences of the operative length and intraoperative blood loss between group C and group D （P>; 0.05）. There were no statistical significant difference differences of incision length and postoperative hospital stay between the four groups （P>; 0.05）. Conclusion For the urologist with rich retroperitoneoscopic adrenal lesion resection experience, the learning curve of the Goal-oriented retroperitoneoscopic adrenal lesion resection is the accumulation 30 cases of experience.
