Supplementary table: Economic burden of complicated ureteral stent removal in patients with kidney stone disease in the USA

These are peer-reviewed supplementary materials for the article 'Economic burden of complicated ureteral stent removal in patients with kidney stone disease in the USA' published in the Journal of Comparative Effectiveness Research.Supplementary Table 1: Patient Characteristics – Propensity-Score MatchingAim: To examine the medical costs of simple versus complicated ureteral stent removal. Materials & methods: We included adults with kidney stones undergoing simple or complicated cystoscopy-based stent removal (CBSR) post ureteroscopy from the 2014 to 2018 Merative™ MarketScan Commercial Database. The medical costs of patients with complicated and simple CBSR were compared. Results: Among 16,682 patients, 2.8% had complicated CBSR. Medical costs for patients with complicated CBSR were higher than for simple CBSR ($2182 [USD] vs $1162; p Conclusion: Complicated ureteral stent removal doubled the medical costs associated with CBSR. Ureteral stents with anti-encrustation qualities may reduce the need for complicated CBSR and associated costs.
