Analysis of learning curve of primary urologists mastering retroperitoneal laparoscopic radical nephrectomy
Objective To analyze the learning curve of retroperitoneal laparoscopic radical nephrectomy(RLRN)mastered by primary urologists.Methods The clinical data of 40 renal cell carcinoma(RCC)patients who underwent RLRN by the same operator in our hospital from January 2020 to December 2022 were retrospectively analyzed.According to the order of operation,the patients were divided into group A(1-10 cases),group B(11-20 cases),group C(21-30 cases)and group D(31-40 cases).The operation time,intraoperative blood loss and postoperative hospital stay were compared among the four groups,and the learning curve was analyzed.Results Among the 40 patients,2 cases were converted to open surgery,including 1 case in the group A and 1 case in the group B respectively.There were statistically significant differences in operation time,intraoperative blood loss and postoperative hospital stay among the four groups(P<0.05);the operation time and postoperative hospital stay of the group C and the group D were shorter than those of the group A and the group B,and the intraoperative blood loss was less than that of the group A and the group B(P<0.05);there was no significant difference in postoperative hospital stay between the group A and the group B(P>0.05);there were no significant differences in operation time,intraoperative blood loss and postoperative hospital stay between the group C and the group D(P>0.05).The analysis of the learning curve found that the primary urologist could achieve proficiency and relatively stable level in RLRN after about 24 cases of learning.Conclusion Primary urologists master the learning curve of RLRN in about 24 cases.
