Abstract
OBJECTIVE: We assessed whether increased BMI has a negative impact in children undergoing robot assisted laparoscopic pyeloplasty (RALP). PATIENTS AND METHODS: Records of patients who underwent RALP were retrospectively reviewed and separated into healthy weight, overweight, and obese cohorts based on age-adjusted BMI percentile, and surgical and postsurgical outcomes were evaluated. RESULTS: Of the 103 patients, there were 79 healthy weight and 24 overweight, with 10 of the 24 considered obese (BMI<85th, ≥85th, and ≥95th percentile for age, respectively). Cohorts were similar in respect to age, sex, laterality and symptoms. Operative time (234 min, 241 min, p=0.642; 254 min, p=0.324), EBL (7.1 ml, 10.5 ml, p=0.293; 6.8 ml, p=0.906), length of stay (1.2d, 1.2d p=0.545; 1.1d p=0.550), and narcotic administration (0.25 mg/kg, 0.25 mg/kg, p=0.545; 0.13 mg/kg, p=0.430) were similar between healthy weight, overweight, and obese cohorts, respectively. Complication rates were similar in regard to minor and major complications. There was no difference in decreased hydronephrosis (92.2%, 89.6%, p=0.440; 88.9%, p=0.730). Four patients (3.4%) required a reoperative procedure (three healthy weight, one overweight; p=NS). CONCLUSIONS: Despite the potential difficulties with surgery in overweight patients, our data indicate that robot-assisted laparoscopic pyeloplasty can be performed as safely and effectively in overweight or obese children as in healthy weight children.
