Laser zaps away urinary blockages better than Old-School knife?

This study compared two ways to treat a narrow urethra (the tube that carries urine out of the body) in 60 men aged 18 to 70. One method uses a laser, the other a cold knife. The goal was to see which works better at improving urine flow after 30 days. The findings could help standardize care and make laser treatment more available in public hospitals.
