In laser therapy, the new greenlight power laser has the greatest significance. The greenlight laser has the advantage that the green light is optimally absorbed by red blood vessels and blood-rich tissue and the irradiated tissue evaporates without bleeding. Thus, the greenlight laser becomes a high-precision'light scalpel' in the hand of the surgeon. Immediately after the bloodless evaporation of the tissue, the urine flow is free again, a strong urinary stream is the result, so that the bladder can be emptied in an unhindered manner again.
After the procedure, however, more urination symptoms are to be expected.
