Body mass index, body fat percentage, and the effect of body fat mass on SWL success.

Objectives: In the present study, we investigated the effects of the Body Mass Index (BMI), the Body Fat Percentage (BFP), and the Body Fat Mass (BFM) on success of SWL, prospectively.

Patients And Methods: The BMI, BFP, BFM values of patients, who were treated by SWL due to upper urinary system stone disease (pelvis renalis, upper ureter, kidney lower and upper calices) between January and December 2005 in our hospital's urolithiasis center, were measured. Patients with stones smaller than 5 mm or larger than 20 mm and patients who had a stone localized somewhere other than in the upper urinary system, were not included in the study.
