Recurrence of urethral stricture after single internal urethrotomy was investigated in 66 patients with special reference to some factors which would influence restricturing. In the present study, recurrence rate was 16.7% (11 patients). Recurrences occurred within an average of 11.9 months. Factors that had no influence on restricturing were age, aetiology, site of the stricture and duration of indwelling catheterization. On the other hand, stricture length appeared to influence the outcome (chi 2, p < 0.001). Short stricture (< or = 10 mm) showed only 4.4% recurrence rate, while 42.9% in long stricture (> 10 mm). Internal urethrotomy appeared to be effective particularly when the stricture was short, while it seemed difficult to treat long strictures by single internal urethrotomy.
对66例接受单次尿道内切开术的患者的尿道狭窄复发情况进行了调查，特别关注了一些可能影响狭窄复发的因素。在本研究中，复发率为16.7%（11例患者）。复发平均发生在11.9个月内。对狭窄复发无影响的因素包括年龄、病因、狭窄部位和留置导尿管时间。另一方面，狭窄长度似乎影响治疗结果（卡方检验，p<0.001）。短狭窄（≤10mm）的复发率仅为4.4%，而长狭窄（>10mm）的复发率为42.9%。尿道内切开术似乎对短狭窄特别有效，而单次尿道内切开术治疗长狭窄似乎很困难。
