In this single center, double-blind, randomized controlled clinical trial, we will include 648 diabetes patients aged 18-70 undergoing laparoscopic pelvic tumor resection under general anesthesia. They will be randomized to the following four groups: high-pressure pneumoperitoneum (10mmHg)+ deep neuromuscular block group, high-pressure pneumoperitoneum (15mmHg)+moderate neuromuscular block group, low-pressure pneumoperitoneum + deep neuromuscular block group and low-pressure pneumoperitoneum+moderate neuromuscular block group. Neuromuscular block will be induced by rocuronium bolus and maintained by a continuous infusion of rocuronium. Deep neuromuscular block is defined as PTC 1-2, and low neuromuscular block is defined as train-of-four TOF twitch 1-2. The primary outcome will be serum Cystatin C level, and the secondary outcomes will be serum creatine level, urinary sediment, intraoperative urine output, duration of surgery, surgical space condition and occurrence bucking and body movement.

Deep neuromuscular block is defined as post tetanic count (PTC) 1-2, and low neuromuscular block is defined as train-of-four (TOF) twitch 1-2. The outcomes will be indicators for acute kidney injury and surgical condition.
