The goal of this clinical trial is to compare two kind of trocar in patients undergoing complex robot-assisted partial nephrectomy. The main question it intends to answer is whether the use of valveless trocars can significantly reduce carbon dioxide absorption.
In the literature there are studies on the benefit of valveless trocars in robotic surgery. There are no studies on the potential effects even in complex kidney surgery. Through this randomized study we want to investigate whether the ability to clear CO2 is better using valveless trocars

the valveless trocar will be used instead of the standard trocar - these trocars are used for insufflation of carbon dioxide into the abdomen
standard trocar, usually camera port for robotic surgery

RECRUITINGcarbon dioxide elimination rate: using the formula where end tidal carbon dioxide multiplied by minute volume divided by arterial pressurea (760mmHg) multiplied by patient weight
Time frame: before extubation
postoperative acute pain: using the NRS scale
Time frame: at 1 hour and at 4 hour after the end of surgery
subcutaneous emphysema: through clinical observation at the end of the intervention
Time frame: at 30 minutes afetr the end of anesthesia
