Abstract

Er:YAG laser performs a precise urethral incision with minimal thermal damage in urethral stricture disease, which is characterized by a narrowing of the urethra. A laser that can precisely vaporize or incise the scar tissue at the site of the urethral stricture with minimal peripheral thermal damage to adjacent healthy tissue may produce higher success rates. removal. The laser's 2.94-μm wavelength exactly matches a major water absorption peak in tissue, allowing precise tissue ablation with minimal thermal insult to adjacent healthy tissue. This laser can incise urethral tissue with approximately 20 times less thermal damage than the other lasers. Five patients were treated for the disease in the Davison laser center with this laser. The success of the procedure was evaluated by comparing the patient's rate of urination before and after surgery. All the five patients were treated successfully with no complications resulting from the procedure.
