The Surgical Management of Kidney Stone Disease in the Province of Ontario: A Population Based Time Series Analysis

A population based cross-sectional time series analysis was conducted using three Ontario administrative databases, to assess trends over time in the surgical management of kidney stone disease. All kidney stone treatments performed with extracorporeal shockwave lithotripsy (SWL), ureteroscopy (URS) and percutaneous nephrolithotomy between July 1, 1991 and December 31, 2010, were included. Time series modeling with exponential smoothing and autoregressive integrated moving average models demonstrated a significant increase in the utilization of URS over time (23.69% to 59.98%, p<0.0001), with a reciprocal significant decrease in the utilization of SWL (68.77% to 33.36%, p<0.0001). As a result of this shift in treatment paradigm, time series modeling also demonstrated an associated significant decrease in the need for ancillary treatment over time (22.12% to 16.01%, p<0.0001) and a significant increase in the need for hospital readmission (8.01% to 10.85%, p<0.0001) or emergency room visit (7.58% to 9.95%, p=0.0024) within 7 days following treatment.
