Xi 'an 45 1 Hospital adopts the most advanced technology in China-the sixth generation minimally invasive plastic surgery for prepuce in Korea to treat phimosis and redundant prepuce. The 6th generation of Korean prepuce surgery, 10 minute operation, has beautiful appearance, and the postoperative sexual ability is improved by 2-3 times, without repeated treatment. It has replaced the previous Korean prepuce plastic surgery and become a good method for the treatment of a new generation of redundant prepuce. Xi 'an 45 1 Hospital has been used in urology for less than three years, and has benefited 20,000 patients with redundant prepuce and phimosis. The sexual ability has been improved by 2-3 times, and the satisfaction rate is 100%. We remind that men with long foreskin, especially phimosis patients, have a higher incidence of penile lesions. Therefore, early treatment of redundant prepuce and phimosis is the best measure to prevent penile tumors.
