Patients were categorized as morbidly obese (BMI>35, n=63) or non-obese/control (BMI<35, n=254). Not surprisingly, radiolucent stones were significantly more prevalent among the morbidly obese (42% vs. 12%), as well in those with hyperlipidemia (34% vs. 15%) and the metabolic syndrome (46% vs. 16%). When evaluating the efficacy between the groups, however, the results were a bit more surprising. Mean stone size between the obese and control groups was comparable (9.7 and 10.1mm), as was stone clearance after repeated ureteroscopic procedures, (95.9% and 93.8%) and complication rates (3.23% vs. 1.87%).
While the efficacy and safety of ureteroscopic procedures in the obese appears equivalent to their non-obese counterparts, it would be interesting to compare the type and degree of complications that occurred as well operative times.
