Purpose

We investigated the patients who underwent ESWL to find out which factors influenced the outcome and built a logistic regression model to estimate the probability of stone free after ESWL.

Material and methods

From January 2013 to December 2013, we retrospectively reviewed the clinical status of 641 patients with solitary urinary calculus who underwent ESWL in our hospital. These patients were divided to the renal stone group and the ureteral stone group. We analyzed the pre-ESWL characteristics of these patients.

Results

The stone-free rate was 54.8% in all patients. The stone-free rates were 46.7% and 67.8% in renal stone group and ureteral stone group, respectively. In the multivariate logistic regression for the renal stone group, BMI, stone length and stone width are the independent factors which affect the success rate. In the multivariate logistic regression for the ureteral stone, only stone length is the independent factor. A logistic regression model was designed to estimate SFR, which has a sensitivity of 77.8% and specificity of 75.5%.

Conclusion
BMI, stone length, stone width, and kidney or ureteral stone are all prognostic factors influencing the outcome of ESWL. Logistic regression model to predict SFR can help us evaluate whether the patient has favorable outcome after ESWL or not.
