Abstract
Percutaneous laser discectomy has potential advantages over conservative therapy and classical open surgery as a minimally invasive procedure, although clinical experiences are limited. We experienced a patient treated with herniated lumbar discs using Nd:YAG laser. A 55-year-old woman complained of severe back pain with sciatica on L4/5 and L5/S1 dermatome for several months.

Under fluoroscopic guidance, a 14 G biopsy needle was inserted into the L4/5 and L5/S1 disc spaces to the margin of the nucleus pulposus. Laser irradiation for vaporization of tissue was performed at 20 W/second to 1200 J. A laser fiber (
