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.
