Furosemide Stress Test Predicting Early Graft Function in Kidney Transplantation

Furosemide is an old drug that has been used frequently in the postoperative period of kidney transplantation, aiming to achieve adequate urine output. There is no previous study that directly evaluate the urine response to standardized dose of furosemide in the postoperative period. The objective is to measure the urine output after standardized dose of furosemide is delivered, as a biomarker to predict the graft function in perioperative period.

Inclusion Criteria: * Deceased donor kidney transplantation at KCMH * informed consent is accepted Exclusion Criteria: * Known allergy to furosemide * Surgical complication of allograft * Urgently needed for dialysis (refractory hypervolemia, uremic symptoms, and hyperkalemia)
