Both ureteroscopy (URS) and shock wave lithotripsy (SWL) are cornerstones in the surgical management of urolithiasis in the United States. We hypothesized that URS utilization outpaced SWL utilization in recent years and quantified the magnitude of change over time for caseloads of URS and SWL among urologists from a national Medicare database. Using the public "Medicare Physician & Other Practitioners" database (https://data.cms.gov), we determined case numbers of SWL (current procedural terminology [CPT] 50590) and URS (CPT 52356 or 52353) from 2012 to 2019. In a subanalysis, we identified "high-volume stone urologists" as those in the upper quartile of case numbers for both SWL and URS in baseline years of either 2012 or 2013 and trended their caseload from 2012 to 2019. Linear estimation models assessed annual rates of change and their statistical significance. In 2012, urologists performed 41,135 SWL procedures 21,184 URS. URS overtook SWL in 2017 and by 2019 was the dominant modality (60,063 URS 43,635 SWL). Between 2012 and 2019, total URS cases annually increased by 5700 (15%/year, < 0.001), while the number of SWL cases peaked in 2015 and has since declined on average -1.6%/year ( = 0.020). The number of urologists performing URS steadily rose from 1147 in 2012 to 2809 in 2019, reflecting an additional 246 urologists (21%/year) performing URS annually. The caseload of high-volume stone urologists showed similar trends with average URS cases increasing by 2.9/year/urologist (9.8%/year, < 0.001) and average SWL cases declining by 0.9/year/urologist (-1.7%/year, = 0.023). URS utilization has increased dramatically and outpaced SWL utilization from 2012 to 2019 within the Medicare population. URS was increasingly used by both the general urologist population and high-volume stone urologists while SWL utilization has begun to decline.
在美国,输尿管镜检查(URS)和体外冲击波碎石术(SWL)都是治疗尿石症的基石。我们假设 URS 的使用率在近年来超过了 SWL 的使用率,并从 Medicare 国家数据库中的泌尿科医生那里量化了 URS 和 SWL 的病例数量随时间的变化。
我们使用公共的“医疗保险医生和其他从业者”数据库(https://data.cms.gov),确定了 2012 年至 2019 年 SWL(当前程序术语 [CPT] 50590)和 URS(CPT 52356 或 52353)的病例数量。在一个子分析中,我们将那些在 2012 年或 2013 年基线年份中 SWL 和 URS 的病例数量均排在前四分之一的“高容量结石泌尿科医生”确定为高容量结石泌尿科医生,并从 2012 年到 2019 年追踪他们的病例数量。线性估计模型评估了年度变化率及其统计学意义。
2012 年,泌尿科医生共进行了 41135 次 SWL 手术和 21184 次 URS 手术。2017 年,URS 超过了 SWL,到 2019 年,URS 成为主导模式(60063 次 URS 和 43635 次 SWL)。2012 年至 2019 年间,URS 病例数量每年增加 5700 例(每年增加 15%, < 0.001),而 SWL 病例数量在 2015 年达到峰值,此后平均每年下降 1.6%( = 0.020)。进行 URS 的泌尿科医生数量从 2012 年的 1147 人稳步增加到 2019 年的 2809 人,反映出每年有 246 名额外的泌尿科医生(每年 21%)进行 URS。高容量结石泌尿科医生的病例数量也呈现出类似的趋势,平均 URS 病例每年增加 2.9/年/医生(每年增加 9.8%, < 0.001),平均 SWL 病例每年减少 0.9/年/医生(每年减少 1.7%, = 0.023)。
2012 年至 2019 年间,在 Medicare 人群中,URS 的使用率大幅增加,并超过了 SWL 的使用率。URS 不仅被普通泌尿科医生人群广泛使用,而且也被高容量结石泌尿科医生广泛使用,而 SWL 的使用率开始下降。
