Abstract: Purpose:To establish an experimental model of laparoscopic partial nephrectomy (LPN) in rats and to analyze morphological alterations in the renal parenchyma utilizing an electric cautery and harmonic scalpel. Methods: Forty Wistar rats were used, divided in 2 experiments with 20 rats each: experiment I, LPN was performed with an electric cautery and the rats were subdivided into groups A and B; experiment II, LPN was performed with a harmonic scalpel and they were subdivided into groups C and D. The animals … Show more

“…In one study to practice bariatric surgery in rats, the authors used the pressure of 8 mmHg and 11mm trocar. Meyer et al 16 to establish a model of partial nephrectomy, used 20 Wistar rats and established pneumoritônio with pressure of 5 mm Hg and a 5mm trocar. Ettinger et al 15 , as well as the Meyer et al 16 , used a pressure of 5 mmHg for establishing pneumoperitoneum.…”

Ettinger et al 15 , as well as the Meyer et al 16 , used a pressure of 5 mmHg for establishing pneumoperitoneum. However, in our experiment, we used a 2.7-mm of trocar size, because the animals used, has a smaller size and weight than the animals used in Meyer et al 16 and Ettinger et al 15 .…”

“…Just subcarinal lymph node dissection causes ischemic change in bronchial stumps [2]. In addition, the electric scalpel causes greater tissue damage in animal experiments [3]. We think that using an electric scalpel causes bronchial fistulas and perforation.…”
