INTRODUCTION: This study aimed to investigate the relationship between surgical difficulty and postoperative complications in kidney transplantation, as well as to develop a preoperative prediction model for assessing surgical difficulty. METHODS: This is a prospective cohort including 122 kidney transplant adult recipients. The subjective score for operative difficulty, ranging from 1 to 3 points, served as the quantitative measure of surgical difficulty. Analysis of variance and chi-square tests were employed to investigate the differences in postoperative complications. Additionally, Pearson and Spearman correlation analyses were conducted to assess the relationship between preoperative data and surgical difficulty scores, while multiple linear regression analysis was utilized to develop a prediction model. RESULTS: With the increase of surgical difficulty, the incidence and severity of postoperative complications of kidney transplant recipients increased significantly (1 vs. 2, p = 0.009; 1 vs. 3, p = 0.004; 2 vs. 3, p = 0.004). The incidence of delayed graft function and graft loss was relatively high (1 vs. 2, p < 0.001; 1 vs. 3, p < 0.001; 2 vs. 3, p = 0.131). The source of donor kidney, number of arteries after donor kidney trimming, end resistance index of in vitro perfusion, vascular anastomosis mode of recipient, BMI, and calcification of the vessels to be anastomosed were influencing factors of surgical difficulty. The results of linear regression analysis showed ...
