Life-expectancy may rule out need for prostate cancer screening
U.S. trial shows no early mortality benefit from annual prostate cancer screening
March 18,
2009 -- The prostate cancer screening tests that have become an annual ritual for many men don't appear to reduce deaths from the disease, at least among those with a limited life-expectancy, according to early results of a major U.S. study involving 75,000 men.

Surgery with less pain, blood
New for kidney cancer: robotic surgery
June 27,
2008 -- Surgery to remove a kidney tumor is no longer a hands-on operation. Sam Bhayani, a urologic surgeon at the school of Medicine, has pioneered robotic surgery for kidney cancer. Instead of standing for hours with his arms raised above the patient, Bhayani sits at a nearby computer console to maneuver joystick-like controls that guide robotic scalpels, scissors and high-resolution cameras.

Two tests better than one
Prostate cancer screening practices examined
March 16,

Finding the right PSA number
Though not perfect, blood test for prostate cancer is still recommended
Nov. 29,
2004 -- The prostate-specific antigen (PSA) test is a common way to detect prostate cancer in its earliest stages. The exact number of a dangerously high PSA count is constantly under debate and varies among men in different age groups. Despite its imperfections, WUSM urologic surgeon Arnold Bullock still recommends the test be taken annually by men over 50.

Science meets science fiction
Newly grown kidneys sustain life in rats
June 22,
2004 -- Growing new organs to take the place of damaged or diseased ones is moving from science fiction to reality, according to researchers at Washington University School of Medicine in St. Louis. Scientists have previously shown that embryonic tissue transplants can be used to grow new kidneys inside rats. In their latest study, though, they put the new kidneys to an unprecedented and critical test, removing the rat's original kidneys and placing the new kidneys in position to take over for them. The new kidneys were able to successfully sustain the rats for a short time.
