Introduction & Objective :

To evaluate whether body mass index (BMI) has an impact on the outcomes of ultrasound-guided percutaneous nephrolithotomy (PCNL).


Methods :

 The data of 359 patients who required PCNL between June 2013 and July 2016 were reviewed, the patients were divided into 4 groups based on BMI: 2. Baseline characteristics and outcomes were compared between groups. Multivariable logistic regressions were used to evaluate the independent contribution of BMI as a predictor of outcomes. Modified Clavien classification was used for reporting complications. Results were compared between groups using the chi-square and multivariate logistic regression tests.


Results :

No significant differences were noted in demographic data between the 4 groups. Ultrasound screening time, total operative time, and hospital stay increased with increasing BMI. No difference was found in the complication rate, stone free rate, or need for auxiliary procedures. 


Conclusions :

 


 


Obesity does not increase complications in ultrasound-guided PCNL, and the efficacy of the technique for obese patients is similar to that for normal weight patients.
