摘　　要：目的:探讨能谱CT结石成分分析在泌尿系结石体外冲击波碎石(ESWL)中的应用效果。方法:选取2022年5月—2023年8月惠州市中心人民医院门诊治疗的160例泌尿系结石患者,按照随机数表法将其分为两组,各80例。两组均接受ESWL治疗,在此之前,对照组采用常规CT平扫进行结石密度计算,试验组采用能谱CT进行结石成分评估。比较两组手术相关情况、结石清除率及并发症发生率。结果:试验组一次碎石成功率高于对照组,平均体外冲击波次数、最高工作电压平均值低于对照组,平均碎石时间短于对照组,差异有统计学意义(P<0.05)。试验组结石清除率为95.00%,高于对照组的83.75%,差异有统计学意义(P<0.05)。试验组>24 h肉眼血尿发生率均低于对照组,差异有统计学意义(P<0.05);但两组其余并发症发生率比较,差异无统计学意义(P>0.05)。结论:在泌尿系结石ESWL中应用能谱CT结石成分分析能为手术创造有利条件,确保一次碎石成功,提高术后结石清除率,并减少平均体外冲击波次数,缩短手术时间,降低>24 h肉眼血尿发生率。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.
