A kidney tray is a shallow kidney shaped basin, widely used in surgical procedures for carrying dressing, bandages, small instruments, soiled dressing and other medical waste. It can be held close to a patient's body conveniently because of its shape. Enamel coated Kidney Trays were replaced by the stainless steel ones. Today, the Plastic Kidney Trays, in addition to the disposable ones, are greatly in demand.Â
