Abstract：Objective To explore the value of spiral CT in the treatment of complex calculi with multi-mirror combined with lithotripsy.Methods From January 2016 to October 2018,60 patients with complicated calculi were initially diagnosed in our hospital by color Doppler ultrasound and abdominal plain film.They were divided into experimental group and control group by simple randomization method,with 30 cases in each group.In the experimental group,spiral CT scan and three-dimensional reconstruction were performed,and the established model was used to locate the stones and guide the selection of treatment options.In the control group,ordinary CT scan was used to guide the selection of surgical program.The operation time,postoperative hospitalization time,diagnostic effect,stone removal rate and complication rate were compared between the two groups.The value of spiral CT in the treatment of complex calculi with multi-mirror combined with lithotripsy was discussed.Results The diagnostic coincidence rate of stones in the experimental group was higher than that in the control group,and the difference was statistically significant(P<0.05).The primary stone clearance rate,secondary stone clearance rate and total stone clearance rate in the experimental group were all higher than those in the control group,with statistically significant difference(P<0.05).The operation time and hospitalization time of the experimental group were shorter than that of the control group,and the differences were statistically significant(P<0.05).The total incidence of postoperative complications in the experimental group was lower than that in the control group,and the difference was statistically significant(P<0.05).Conclusion Spiral CT can accurately diagnose stones,clear the three-dimensional structure of stones and kidneys,and guide multi-mirror combined with lithotripsy in the treatment of complex calculus.It is worthy of clinical application.
