Researchers have demonstrated that inducing a kind of hibernation state could help protect organs from damage when blood circulation is stopped during surgery. The technique slows down the metabolism and has been found to work well in tests in mice.

A new experimental treatment could help treat end-stage liver disease – by growing tiny new livers elsewhere in the patient’s bodies. The technique, pioneered by cell therapy company LyGenesis, is due to begin human clinical trials within weeks.

Organ transplants can be life-saving, but matching blood types means many people are left on waiting lists. Cambridge scientists have now demonstrated a technique that could one day make donated organs universal, by converting them to blood type O.

Presently, in order to check if someone has chronic kidney disease, a urine sample has to be sent off to a well-equipped lab for testing. A new portable device, however, could allow such testing to be performed onsite in remote communities.

How exactly kidney cells transport blood through the organ's tubes has remained a mystery. Now researchers at Johns Hopkins University have investigated the mechanical forces at work and found a previously unobserved pumping action by kidney cells.

Although kidney stones can be treated with medication, larger ones are often broken up with an endoscopic laser. A new hydrogel is now claimed to be capable of removing even the smallest of the resulting fragments, instead of just leaving them.

An article is reporting on the first 19 humans treated with a new non-invasive method designed to break up kidney stones using sound waves. The method successfully fragmented most kidney stones, promising a non-surgical way to treat patients.

Patients with kidney failure require regular dialysis, an invasive and potentially risky treatment. But now researchers have successfully demonstrated a prototype bioartificial kidney, which can be implanted and works without the need for drugs.

Researchers have discovered a population of natural barometers that monitor and maintain our blood pressure. The cellular sensors have for decades been presumed to be located in a certain type of cell in the kidney, but have only now been detected.

Results from a trial testing an ultrasound therapy for hypertension show the treatment can deliver meaningful reductions in blood pressure. The treatment is based on a hypothesis that disrupting signals from renal nerves can reduce blood pressure.

Scientists at Pennsylvania State University and Stanford University are reporting a breakthrough that could greatly improve on methods to detect kidney stones, demonstrating a novel type of urine test that can return results in just 30 minutes.

Organ transplants are invasive and donors hard to find. Treating kidney disease with stem cells is an option, and now researchers have isolated and studied kidney stem cells from urine samples, which could be a much easier way to collect them.
