Brief Summary

Postoperative acute kidney injury (AKI) is an important surgical complication that increases hospital stay and mortality when it occurs after kidney surgery. Studies investigating the effects of restrictive or liberal fluid regimen on postoperative AKI during radical/partial nephrectomy have given controversial results. It is important to recognize AKI early so that supportive treatments can be started early. Serum creatinine level, which is frequently used in the detection of AKI, increases late and causes a delay in diagnosis. It has been reported that cystatin C level increases earlier than creatinine in the diagnosis of AKI, so it can be used for early diagnosis.

Outcome Measures

Primary Outcomes (1)

  • rate of acute renal failure

    To determine whether the restrictive or liberal fluid regimen applied during partial or radical nephrectomy surgery causes acute renal failure in the early postoperative period.

    48 hour

Secondary Outcomes (1)

  • Creatinine

    48 hour

Study Arms (2)

R- fluid group

EXPERIMENTAL

The group to which restrictive fluid replacement will be applied (Group R); 3 ml/kg/hour Ringer lactate (RL) solution will be given.

Diagnostic Test: Restrictive

L- fluid group

EXPERIMENTAL

7 ml/kg/hour RL solution will be given to the group that will receive a liberal liquid regimen (Group L).

Diagnostic Test: Liberal

Interventions

RestrictiveDIAGNOSTIC_TEST

3 mL/kg/hour Ringer Lactate will be given peroperatively to the restrictive group (Group R).

R- fluid group
LiberalDIAGNOSTIC_TEST

7 ml/kg/hour Ringer Lactate will be given peroperatively to the liberal group (Group L).

Model Details: Patients will be randomly divided into two groups: restrictive and liberal fluid replacement groups. 3 ml/kg/hour Ringer's lactate (RL) solution will be given to the group that will receive restrictive fluid replacement (Group R), and 7 ml/kg/hour RL solution will be given to the group that will receive liberal fluid regimen (Group L). Patients in both groups will receive 1.5 ml/kg/hour crystalloid fluid replacement on postoperative day 1, and oral intake will be increased on day 2. Serum creatinine, GFR and blood urea nitrogen (BUN) values will be measured in all patients before surgery and 48 hours after removal of the renal pedicle clamp. Patients' blood and blood product replacement, vasopressor and inotrope needs will be recorded. Serum cystatin C level will be measured by taking serum samples before the surgery and at the 48th hour postoperatively.
