The rate at which this happens is not well described in the literature. We aimed to determine the rate at which this occurs as it may have significant cost implications. METHODS Using the Office of Statewide Health Planning Database (OSHPD), a publicly available database for all patients in California undergoing outpatient surgeries in 2008, we identified all patients with ICD-9 diagnosis code for upper tract nephrolithiasis. We used CPT codes to identify all patients in this group who underwent diagnostic URS only versus those that underwent stone treatment during URS (laser lithotripsy or basketing). The negative URS rate was then calculated (diagnostic URS / URS with stone laser lithotripsy or basketing). Rates of negative URS were compared based on sex, race/ethnicity, age, and expected source of payment. RESULTS In the OSHPD database for the year 2008, 9192 patients underwent ureteroscopic procedures with the diagnosis of upper tract stone disease. Of these, 897 patients underwent diagnostic URS. There were 8295 who underwent URS with laser lithotripsy or stone basketing. The rate of negative URS was 9.8%. There were no detectable significant differences in the negative URS rate based on sex, race/ethnicity, or age. The negative URS rate did vary considerably with different insurance types (figure 1). CONCLUSIONS The rate of negative URS is significant and it occurs in nearly 1/10 individuals undergoing URS for therapy of a stone. The possibility of negative URS should be considered when counseling patients pre-operatively. The source of payment may influence the rate of negative URS. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e315-e316 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Remy Lamberts More articles by this author Simon Conti More articles by this author Rajesh Shinghal More articles by this author John Leppert More articles by this author Christopher Elliott More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
