Abstract
OBJECTIVE: To evaluate the impact of the specialty (urologist vs radiologist) of the physician obtaining percutaneous renal access (RA) on perioperative outcomes, complications, and costs of percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: We used data from a national hospital discharge database to identify patients undergoing PCNL between 2003 and 2015. Procedure codes related to RA were linked to physician specialty. We examined patient demographics, Charlson comorbidity index, postoperative complications, length of stay (LOS), and direct hospital costs, as well as hospital and surgeon characteristics stratified by specialty of the physician obtaining RA. A multivariable regression model was created adjusting for potential confounders. RESULTS: We identified 40,501 patients undergoing PCNL between 2003 and 2015. Urologists obtained access in 17.0% of cases. RA by urologists was associated with a lower 90-day complication rate (5.0% vs 8.3%, p < 0.001) and lower rates of prolonged hospitalization ≥4 days (22.5% vs 42.1%, p < 0.001). On multivariable analysis, RA by urologists was associated with lower rates of any complication (Clavien 1-5) (odds ratios [OR] 0.70, p ≤ 0.001), shorter LOS (OR 0.67, p < 0.001), and lower direct hospital costs (OR 0.65, p < 0.001). CONCLUSION: In the United States, radiologists obtain percutaneous RA in the majority of PCNLs. Access by urologists is associated with lower overall complications, shorter hospitalizations, and lower direct hospital costs. Coding errors and absence of stone complexity information may limit the cogency of our findings and requires further investigation.
