自从1974年Sachse介绍了窥视下尿道内切开术以后,这一手术已广泛用于治疗尿道狭窄。然而,有关术后处理及成功标准,则报道各异。作者对81例初次治疗的尿道狭窄患者进行了前瞻性研究。患者平均年龄为64岁(17～88岁)。狭窄部位:膜部43例(53％),球部17例(21％),阴茎部21例(26％)。手术均于窥视下用冷刀切开狭窄段尿道12点处纤维组织。术后均留置尿管,51例狭窄段≤5mm者,术后留置尿管3天,30例狭窄段>5mm者,留置尿管3周(14例)或6周(16例)。6例患者出现 This procedure has been used extensively to treat urethral stricture since Sachse introduced peephole-urethrotomy in 1974. However, the post-treatment and success criteria are reported differently. The authors conducted a prospective study of 81 patients with urethral strictures treated for the first time. The average age of patients was 64 years old (17 to 88 years old). Stenosis: membranous 43 cases (53%), ball in 17 cases (21%), penis in 21 cases (26%). Surgery were in the peep with a cold knife cut narrow urethra at 12 o’clock fibrous tissue. Fifty-one patients had stricture ≤5mm, three days after operation, 30 patients with stricture> 5mm, indwelling catheter for three weeks (14 cases) or six weeks (16 cases). Six patients appeared
