About this trial
It is a prospective, randomized, controlled and superiority clinical trial, with the objective of comparing the effectiveness of multimodal anesthesia versus conventional anesthesia in patients undergoing oncological robotic nephrectomy within a short-stay surgery program (SSA). The effect of no specific drug will be evaluated, but rather the anesthetic approach ologies of surgical patients. The clinical trial will be carried out in a third-level university hospital, between the first half of 2026 and the second half of 2027 and, after approval by the corresponding Clinical Research Ethics Committee.
