Abstract

Objectives: With the prevalence of obesity in the United States, a significant proportion of robot-assisted laparoscopic prostatectomy (RALP) candidates have an elevated body mass index (BMI). We determine if this impacts on the clinical outcomes of RALP. Methods: 218 consecutive patients underwent RALP were identified from a prospectively maintained RALP database recorded and compared for their demographics, clinical outcomes and adverse events in normal weight (BMI 2), overweight (BMI ≥25 and 2) and obese (BMI ≥30kg/m2) groups. Results: 36 normal weight, 115 overweight and 67 obese patients were identified. There were no significant differences in demographic data among the three groups except for mean BMI (23.1 vs. 27.5 vs. 32.8kg/m2, p0.05).Conclusions: Elevated BMI appears to increase the RALP operative time, but has little impact on other intraoperative parameters, clinical outcomes or patient morbidity. RALP is a safe and effective procedure in patients with elevated BMI.
