Resultados de la nefrectomía laparoscópica en pacientes obesos y no obesos

Abstract

Introduction

Obesity has been shown to adversely affect surgical results and so it is considered a relative contraindication for laparoscopy. Increased experience has done away with many obstacles to laparoscopic renal surgery.

Aim

To describe and compare the surgical results of laparoscopic nephrectomies in obese and non-obese patients.

Materials and methods

Seventy-five patients underwent laparoscopic nephrectomy within the time frame of 2011-2015 that was performed by 2 urologists trained in laparoscopic surgery. The cases were divided into obese and non-obese patients. The Student's t test was used to evaluate the variables in the two groups and complications were assessed using the chi-square test.

Results

Twenty-seven patients had normal weight (36%) and 48 had overweight or obesity (64%). In means, hospital stay in days was 3, intraoperative blood loss was 227 ml, and surgery duration was 167 min. Eleven patients had some type of complication (14.7%). Patient age was the only statistically significant variable (P<.008).

Conclusions

Our study suggests that laparoscopic nephrectomy has the same surgical results in obese and non-obese patients. The minimally invasive approach is a safe and feasible technique in the obese population.
