Application of Energy Spectrum CT Calculus Component Analysis in Extracorporeal Shock Wave Lithotripsy of Urinary Calculus
Objective:To investigate the application effect of energy spectrum CT calculus component analysis in extracorporeal shock wave lithotripsy(ESWL)of urinary calculus.Method:A total of 160 patients with urinary calculus treated in the Outpatient Department of Huizhou Municipal Central Hospital from May 2022 to August 2023 were selected and divided into two groups according to the random number table method,with 80 patients in each group.Both groups received ESWL treatment,before this,conventional CT plain scan was used to calculate stone density in the control group,and energy spectrum CT was used to evaluate calculus components in the experimental group.The operative conditions,stone clearance rate and complication rate between the two groups were compared.Result:The success rate of one time crushing in experimental group was higher than that in control group,the average number of extracorporeal shock wave and average value of maximum working voltage were lower than those in control group,and the average crushing time was shorter than that in control group,the differences were statistically significant(P<0.05).The stone clearance rate of experimental group was 95.00%,which was higher than 83.75%of control group,and the difference was statistically significant(P<0.05).The incidence of gross hematuria>24 h in experimental group was lower than that in control group,and the difference was statistically significant(P<0.05);there were no significant differences in the incidence of other complications between the two groups(P>0.05).Conclusion:The application of energy spectrum CT calculus component analysis in ESWL of urinary calculus can create favorable conditions for surgery,ensure the success of one-time lithotripsy,improve postoperative stone clearance,reduce the average number of extracorporal shock wave,shorten the operation time,and reduce the incidence of gross hematuria>24 h.
