口腔黏膜尿道成形术后尿道狭窄复发危险因素的研究进展

Oral mucosal urethroplasty is the standard treatment for complicated urethral stricture or urethral strictures that have failed multiple endoscopic treatments. However, some patients still develop recurrence. At present, the risk factors and related mechanisms of recurrence are unknown, leading physicians to fail to be vigilant in patients with a higher risk of recurrence, resulting in improper treatment. These risk factors, including obesity, smoking history, treatment history, the characteristics of stricture (etiology, length, location) and treatment factors (location of graft, operator experience) were reviewed in this paper. With these risk factors, the corresponding adjustment of the surgical plan can reduce the recurrence rate of postoperative stricture.
