Objective: To determine whether the body mass index (BMI) affects the outcome and mor-bidity of ureteroscopic pneumolitotripsy.
Materials and Methods: From January 2006 to April 2010, 332 patients with ureteral stones ranging 8 mm to 15 mm, who under-went semirigid ureteroscopy (URS) with pne-umolithotripsy, were included in the study. Pa-tients were divided into four groups depending on their BMIs: ideal body weight <25 kg/m2 (group 1), overweight 25 to 29.9 kg/m2 (group 2), obese ≥30 to 34.9 kg/m2 (group 3) and mor-bidly obese ≥35 kg/m2 (group 4). The patients were followed up preoperatively and postope-ratively with abdominal plain radiography, re-nal ultrasonography, intravenous pyelography (IVP) and/or noncontrast spiral computed to-mography (CT) . Patients were considered to have been treated successfully if they had <2 mm residual stones.
Results: A total of 332 ureteroscopy and pneumolithotripsy were performed on 126 fe-male and 206 male, as a total 332 patients. Of these, 282 (85%) were successfully treated with pneumolithotripsy without residual fragments. There were no significant differences in mean stone sizes, stone lateralizations and stone lo-calizations among four groups. Stone-free rates were 84% in group 1, 89% in group 2, 82% in group 3 and 80% in group 4 (p>0.05). We found no significant differences among groups with regard to stone-free rates, complication rates, operative times and hospital lengths of stay.
Conclusions: The results of our study have shown that body mass index had no impact on efficacy or complication rates of ure-teroscopy.
Key Words: Body mass index, ureteral stone, ureteroscopy.
