1. Urethral dilation: simple urethral dilation is only suitable for milder stenosis and postoperative follow-up; 2. Endourethral resection: for patients with short stenosis segments (generally Q5-8mm) and no obvious scar or thin scar; 3. Urethral dissection anastomosis: a better method for treating patients with short stenosis segments (Q2-75px); 4. Urethral substitution (oral buccal mucosa): for patients with complex urethral stenosis and long stenosis segments; 5. New surgical methods such as endoscopic laser resection of urethral stenosis; 6. Balloon dilation of urethral stenosis; 7. Stenting of urethral stenosis.
