Abstract

Background: Laparoscopic donor nephrectomy (LDN) increases incentives to donation by subjects who might refuse an open operation. However, the incidence of delayed graft function is higher after LDN than after open operation. This may be caused by the reduction of renal perfusion as a result of the raised intraabdominal pressure and mechanically induced renal angiospasm during the operation. We conducted experiments to find out whether the application of papaverine around the renal artery during LDN could improve early graft function after transplantation. Methods: Renal function was studied in 10 male pigs (weight ∼25 kg). The left kidney was harvested laparoscopically (intraabdominal pressure 8 mmHg). Five animals were randomly selected to have perivascular application of 50 mg papaverine (treatment group) before preparation of the vessels. In controls no papaverine was used. After LDN and open right nephrectomy the left kidney was autotransplanted. The main outcome measures were volume of urine produced and creatinine clearance during the first 20 h after the transplant. Results: The groups were comparable in respect of body weight, hemodynamic values, amount of infusions, warm and cold ischemia time, and duration of anastomosis. Urine output and creatinine clearance were significantly higher in pigs treated with papaverine than in controls. Conclusions: Papaverine substantially improved early graft function in pigs when applied around the renal artery during LDN. Whether this is applicable to procurement of human kidneys remains to be evaluated.
