Honolulu--A new "one-step" percutaneous access sheath may become the next advance in the evolution of percutaneous nephrostolithotomy, according to D. Duane Baldwin, MD, associate professor of urology at the Loma Linda (CA) University Medical School. Dr. Baldwin has completed the first trials of the device, which weds the dilation balloon to the sheath, allowing the instrument to be advanced to the kidney in a single procedure.
