Application value of three dimensional CT reconstruction in laparoscopic radical nephrectomy
Objective To evaluate the application value of three dimensional computed tomo-graphy(CT)reconstruction in laparoscopic radical nephrectomy for renal tumor.Methods From Jan-uary 2019 to March 2020,a retrospective cohort study was conducted on the clinical data of 40 patients with renal tumor treated by laparoscopic radical nephreclomy.Of which 20 patients were preoperatively based on the enhanced CT imaging data of both kidneys and used three dimensional visualization soft-ware perform fusion imaging reconstruction as the observation group.The other 20 patients was evalua-ted by intensive CT,CT renal artery angiography(CTA)before surgery as a control group.By compa-ring the clinical data of the two groups of patients,including the amount of bleeding,operation time,number of open cases,complications,hospital stay,and tumor recurrence,the significance of three-dimensional reconstruction imaging in laparoscopic nephrectomy was analyzed.Results There were no statistically significant comparisons between the two groups of patients in age,gender,tumor size,tumor stage,ratio of affected side,renal arteriovenous variation,and postoperative complications(all P＞0.05).The operation time,operative blood loss,transfer to open surgery rate and hospital stay of the study group were significantly lower than those of the control group(all P＜0.05).No tumor re-currence or metastasis occurred in the patients.Conclusions Preoperative visualization of CT-based three-dimensional reconstruction for patients with laparoscopic nephrectomy can significantly reduce the occurrence of intraoperative side injuries,avoid transfer to open,shorten the operation and hospitaliza-tion time,and reduce the amount of bleeding.
