Restenosis is most likely to occur within 6 months of urethral stricture, while the likelihood of recurrence decreases significantly after 1 year. The postoperative follow-up included the assessment of postoperative outcome and the occurrence of postoperative complications. 1.Symptom evaluation The subjective feeling of good postoperative effect is smooth urination, thick urine line, no interruption of urination and no urinary bifurcation; on the contrary, poor effect is manifested by poor urination, effort, thin urine line, interruption of urination and incomplete dripping. 2.Related examination Uroflow rate: The maximum uroflow rate is the most significant in the evaluation of the postoperative effect of urethral stricture. The postoperative effect is divided into 3 grades: good – maximum uroflow rate >15ml/s, good – maximum uroflow rate >10ml/s, poor – maximum uroflow rate <10ml/s. 3.Cystourethrography The postoperative cystourethrography can be compared with the preoperative one to evaluate the postoperative effect. 4.Urethrocystoscopy Under direct vision, the site of urethral stricture can be detected and the severity of the stricture and the scarring around the anastomosis can be correctly evaluated to provide an objective basis for the next step of treatment. 5.Urethral probe examination The site, degree, and length of the stricture can be determined. The number of the probe that can be passed through the stenosis site is the rough width of the stenosis. 6.Postoperative complications Erectile dysfunction: most of them are related to neurovascular injury caused by trauma, and re-injury during surgery also has an effect. urethral sphincter implantation.
