Economic burden of complicated ureteral stent removal in patients with kidney stone disease in the USA: Supplementary Table 1
Aim: 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 R ? 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 < 0.0001). Increased stenting time, increased
age, southern US geography and encrusted stent diagnoses were significantly associatedwith complicated
CBSR. 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.
