Urologic applications of the Holmium laser

The Holmium laser has now been in clinical use in urology for several years. The indications for its use continue to expand, and now include lithotripsy and urothelial tumor ablation anywhere in the urinary tract, resection of the prostate, incision of various urinary tract strictures, and vaporization of cutaneous lesions of the external genitalia. The 2100-nm wavelength provides the Holmium laser with a unique combination of vaporization and coagulation, allowing a precise cutting action when higher energy levels are applied. A shallow depth of penetration (< 0.5 mm) in water and tissue allows precise energy application and provides a margin of safety. The machine's user-friendly setup facilitates its operation by urologists and assistance by allied health-care personnel. The multiple urologic applications make the Holmium laser an attractive instrument for everyday utilization by any medium to large urological unit.
