Objective To investigate the clinical effectiveness of laparoscopic ureteropyelotomy combined and treated with surger-y with regional lymph node dissection.Methods From January 2018 to January 2023,42 patients with ureteral cancer were selected from the First Affiliated Hospital of Jinzhou Medical University.Laparoscopic pyeloureterectomy plus sleeve resection of bladder were performed on all patients.Lymph node dissection was performed on patients who met the indications for lymph node dissection before surgery.The demographic characteristics,perioperative results and postoperative complications of the patients were collected.Results The median age of the patients was63 years old(55～70 years old),all42 patients successfully completed the operation,and no ca-ses were converted to open surgery during the operation,among which 14 patients changed their position during the operation,23 pa-tients underwent LND,and no cases died during the perioperative period.The median operation time was 220 min(199～245 min).The median intraoperative blood loss was 128 mL(101～157 mL),the postoperative drainage volume was 62 mL(51～97 mL),and the median placement time of the drainage tube was 3 days.There were 8 postoperative complications.After a mean follow-up of two years,all patients survived without metastasis or recurrence.Conclusion Compared with the traditional operation,the integrated laparoscopic treatment of upper urinary tract urothelial carcinoma has the advantages of short operation time,simple mode and rapid postoperative recovery,which is worthy of further promotion.The combined lymph node dissection can determine the pathological stage,but some perioperative indexes in the NLND group are better than those in the LND group.
