Intravenous Laser Therapy in Patients With Acute Kidney Injury: A Randomized Clinical Trial.

Although intravascular laser irradiation of blood (ILIB) is deemed an innocuous and useful technique for laser therapy, particularly when systemic effects are required, no study, to our knowledge, has been conducted on the effectiveness and innocuousness of ILIB in treating acute kidney injury (AKI).
