Clinical trial study will be carried out. 80 Patients, who have had kidney transplant indications, received dialysis 24 hours preoperatively. Biochemical tests were done and recorded in information form, together with individual characteristics. Patients were divided into two groups, each with 40 patients. Then, each patient received a code and assigned to a group, based on a protocol that determines which code will receive which treatment regimen. One group was named the “Lasix bolus Group” and the other was named the “infusion Lasix”. The bolus dose was initiated within immediately one minute before arterial de-clamping. Infusion was initiated within 30 minutes before arterial de-clamping. Following arterial and venous anastomosis, ureter clamp taking time was checked and recorded in patient’s information form. Diuresis initiation time will be recorded in the samples studied. Finally, urinary output volume was measured until an hour after anastomosis and after each 3 hours for 24 hours, and then in second and third days in ward. Diuresis times in both groups will be determined and compared with each other. The person in charge of measuring will be unaware of Lasix administration method. In addition, the levels of sodium, potassium, BUN, and creatinine will be recorded preoperatively and postoperatively for 4 days.
