    Objective To compare the safety and effectiveness of minimum flow clamping combined with 3D printing technology and highly selective renal artery clamping in laparoscopic nephron sparing surgery. Methods Fifty-two patients with renal cancer undergoing partial resection admitted to Luoyang Central Hospital Affiliated to Zhengzhou University during 2018-01 to 2021-12 were randomly divided into two groups. Group A: 30 cases underwent laparoscopic partial nephrectomy by minimal blood flow clamping combined with 3D printing technology; Group B: 22 cases underwent laparoscopic partial nephrectomy by highly selective renal artery clamping technology. The operative time, renal artery branch clamping time, intraoperative blood loss, postoperative renal function injury and complication rate were compared between the two Groups. Results The operative time,blood loss, renal function injury and complication rate of Group A were shorter than those of Group B (P< 0.05).The time of renal artery clamping in Group B was shorter than that in Group A (P< 0.05). There was no statistical significance in the positive rate of resection margin between the two Groups (P> 0.05).Conclusions In laparoscopic nephron sparing surgery, minimum blood flow clamping technology can not only meet the requirements of accurate tumor resection, but also maximize the preservation of residual renal function, greatly shorten the operation time, reduce the amount of blood loss, and reduce the incidence of perioperative complications, which is worthy of promotion in clinical work.
