Pneumoperitoneum preconditioning for the prevention of renal function after laparoscopic partial nephrectomy: protocol for a double-blind randomised controlled trial.


ABSTRACT: INTRODUCTION:Renal ischaemia reperfusion injury is an inevitable pathophysiology in different clinical situations including laparoscopic partial nephrectomy (LPN), which can obviously decrease the renal function after surgery. Pneumoperitoneum preconditioning (PP) is a promising approach that can yield a protective effect on kidney, which has already been demonstrated in some animal models. The present study is designed to assess whether the PP can yield a clinical renoprotective role after LPN. METHODS AND ANALYSIS:This study is a randomised, prospective, double-blind and parallel controlled clinical trial. Eligible participants will be patients with renal tumours and willing to choose elective LPN. Patients randomised to the treatment arm will receive PP consisted of three cycles of 5?min insuf?ation and 5?min desuf?ation before LPN, while the control arm will receive a sham operation. The primary endpoints are glomerular filtration rate and the level of serum cystatin C within 6 months after desuf?ation. The secondary endpoints are serum creatinine, estimated glomerular filtration rate, alanine transaminase, serum amylase, intestinal fatty acid binding protein, postoperative hospital stay, the incidence of adverse events and mortality in postoperative 6 months. ETHICS AND DISSEMINATION:This study has been approved by the institutional ethics committee of Nanjing First Hospital. The results of this study will be reported faithfully through scientific conferences or published articles. TRIAL REGISTRATION NUMBER:NCT03822338.
