Artificial kidneys may sound like something from a science fiction movie, but these ground-breaking new treatments are currently being designed and tested across the globe. Artificial kidneys may be wearable or implantable options for kidney replacement therapy; xenotransplant, including chimera, or another non-human organ platform may also be considered. Some kidney transplant candidates have a very low chance of getting a kidney transplant because their immune systems are "highly sensitized" to most kidney donors. It promises a much higher quality of life for millions worldwide with kidney failure.. Med. Traditional dialysis machines use filters whose polymer membranes have a wide variation in pore size, meaning that they are inefficient in filtering the blood. Sorry, currently not accepting new patients, but might later. A minority of patients live with transplanted kidneys, thanks to a pool of donated kidneys that are constantly in high demand. With a nanopore silicon membrane, waste fluid (yellow) created by hemofiltration flows into the patients urinary bladder. Approximately 850 patients will be enrolled. is the current Editor-in-Chief of CKJ. Recommended Reading: Kidney Stone Size Chart In Mm. Dr Roy: We are using technology borrowed from the semiconductor electronics industry to precisely pattern silicon wafers into filtration membranes that mimic the function of the native kidneys. In humans, nephron number varies widely and a low nephron endowment at birth and/or a loss of nephrons throughout life is strongly associated with kidney disease .
