Trends and inequalities in the surgical management of ureteral calculi in the United States - Abstract

OBJECTIVE: To assess trends in surgical management of ureteral calculi over a ten year period.

MATERIALS AND METHODS: An analysis of the 5% Medicare Public Use Files (years 2001, 2004, 2007 and 2010) was performed to assess the use of URS, SWL and UL in treating ureteral calculi. Patients were identified using ICD-9 (cm) and CPT codes. Statistical analyses, including the Fisher, χ2 tests, and multivariate logistic regression analysis (dependent variables: URS, SWL, UL, treatment, no treatment; independent variables: age, gender, ethnicity, geography and year of treatment) were performed using SAS 9.3 (SAS Institute Inc., Cary, NC) and SPSS v20 (IBM Corp., Armonk, NY).

RESULTS: A total of 299,920 patients were identified with ureteral calculi. Of these, 115,200 underwent surgery. Men (OR=1.15, p< 0.0001) were more, while minorities (OR=0.84, p=0.004) were less likely to be treated. Patients in the West were also less likely to be treated (OR=0.76, p< 0.0001) as were patients aged < 65 or > 84 years old (p=0.29). URS represented the predominant surgical approach (65.2%), followed by SWL (33.6%) and UL (1.2%). The relative usage of URS increased over time, while SWL and UL declined. Women (OR=1.25, p< 0.0001) were more likely to undergo URS. Patients in the South (OR=1.51, p< 0.0001) and minorities were more likely to undergo SWL (OR=1.23, p=0.03).

CONCLUSIONS: The surgical treatment of ureteral calculi changed significantly from 2001-2010. The utilization of URS expanded at the expense of SWL and UL. Multiple inequalities existed in overall surgical treatment rates and in the choice of treatment: Age, gender, ethnicity, and geography influenced both whether patients underwent surgical intervention and the type of surgical approach used.
