Purpose: To evaluate the impact of body mass index (BMI) on clinical outcomes and safety profiles of percutaneous nephrolithotripsy (PCNL).
Materials and Methods: We retrospectively reviewed the patients who received percutaneous nephrolithotripsy (PCNL) between January 2015 and December 2016. A total of 184 consecutive patients were enrolled. The patients were categorized into 3 groups according to BMI (normal: BMI ≤ 24, overweight: 24 < BMI ≤ 27, obesity: BMI > 27). The stone clearance rate, operation time, duration of hospital stay, post-operative analgesic use and post-operation complications were compared among groups. The categorical variable was analyzed by Chi square test, and the continuous variable was analyzed by Kruskal-wallis test. The possible prognosticators for stone clearance were also analyzed using logistic regression method.   
Results: There were no significant differences among groups in terms of age, gender, stone character, stone size, and laterality. A higher proportion of hypertension were observed in the larger BMI groups, and lower hemoglobin level in the smaller BMI group. No significant differences of stone clearance rate (66%, 76%, 70% in normal size, overweight and obesity groups, respectively), duration of hospital stay, post-operative analgesic use, and complication rate were identified among groups. The most common complication was post-operative fever in all groups. Multivariable analysis showed the stone character was a significant prognosticator for stone clearance.
Conclusion: BMI did not reveal impact on the stone clearance, operative time, duration of hospital stay, postoperative analgesic requirement, and postoperative complication in patients undergoing PCNL.
