Purpose: To evaluate the efficacy and safety of percutaneous nephrolithotomy PCNL in morbidly obese Body mass index BMI >35 kg/ m2 patients and compare the outcomes of the operation with normal weighted BMI = 18.5 – 25 kg/m2 patients. Material and Methods: We evaluated the perioperative and stone-related outcomes following PCNL in morbidly obese and normal weighted patients retrospectively. 32 morbidly obese and 112 normal weighted patients enrolled into this study. Results: Mean ages of normal weighted and morbidly obese patients were 45.3 and 42.6, respectively. The morbidly obese patients demonstrated higher rates of diabetes mellitus 70.5% vs. 7.1%, p < 0.05 and cardiovascular disease 47% vs. 3.5%, p < 0.05 . Mean stone dimesion in long axis was 2.3±0.9 cm. Mean operative duration was longer in the morbidly obese group 106 ±46 min vs. 78 ± 38.5 min, p =0.07 . Stone-free rates were similar between two groups 83.9% vs. 82.3%, p >0.05 . There was no significant difference in the transfusion rate and the length of hospital stay. There was no statistically significant difference between complication rates in two groups 9.8% vs. 8.8%, p >0.05 . Comment: Percutaneous nephrolitotomy is safe and effective procedure in morbidly obese patients.
