Ischemia Reperfusion Injury Clinical Trial
Official title:
Pneumoperitoneum Preconditioning for the Prevention of Renal Function After Laparoscopic Partial Nephrectomy: a Double-blind Randomized Controlled Trial
The present study is designed to investigate the short-term and long-term renoprotective role of pneumoperitoneum preconditioning in patients undergoing laparoscopic partial nephrectomy.
Renal ischemia reperfusion injury (IRI) is an inevitable event in patients undergoing laparoscopic partial nephrectomy (LPN), which can obviously affect the post-operational renal function. Pneumoperitoneum preconditioning (PP) is a promising strategy to render a protective effect on kidney, which has been already confirmed in some clinical settings. This study is designed as a randomized, prospective, double-blind and parallel controlled clinical trial to assess the short-term and long-term renoprotective role of pneumoperitoneum preconditioning in patients undergoing laparoscopic partial nephrectomy, and observe its effect on the other abdominal organs. Patients with renal tunours and willing to accept elective LPN will be screened as eligible participants. The investigators aim to enroll 86 subjects. Patients randomized to the treatment arm will receive PP consisted of three cycles of 5 min insufflation and 5 min desufflation before PLN, while the control arm receive a sham operation. ;
