Category: Clinical Stones: PCNL
Introduction & Objective :
To evaluate whether body mass index (BMI) has an impact on the outcomes of ultrasound-guided percutaneous nephrolithotomy (PCNL).
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.
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.
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.
