Innovation in laser treatment results in the ambulatory resection of prostatic adenomas and carcinomas

For the treatment of prostate anew instrumentation set is built. This allows an ambulant resection of the prostate by using a combination method of laser and radio frequency (RF). Both instrumentations were combined in a new laser RF resectoscope which consists of a shaft and two working elements; one for the laser fiber and one for the RF loop. The treatment first coagulates the prostate tissue with laser by using a simple bare fiber that irradiates lateral. Since the fiber can be moved manually in axial direction by means of the laser fiber carrier all sections of the prostatic tissue can be systematically covered by the laser beam. Thus substitutes costly and sophisticated systems, i.e. side firing fibers. Further benefits are given; so the instrumentation can also be used for bladder tumors, urethral strictures and bladder neck incisions.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.
