Urethral strictures that are impassable in retrograde fashion present a special problem to the urologist because they cannot be managed by standard dilatation techniques or direct-vision internal urethrotomy. Open urethroplasty is usually required. We describe a technique to catheterize the urethra in an antegrade fashion and dilate the strictures. Our study involved six patients with impassable urethral strictures that were successfully traversed and dilated. Percutaneous transvesical antegrade catheterization and balloon dilatation are beneficial for patients with bladder outlet obstruction.
逆行无法通过的尿道狭窄给泌尿外科医生带来了一个特殊问题，因为它们无法通过标准的扩张技术或直视下尿道内切开术进行处理。通常需要进行开放性尿道成形术。我们描述了一种经尿道顺行插管并扩张狭窄的技术。我们的研究纳入了6例逆行无法通过的尿道狭窄患者，这些狭窄均成功通过并扩张。经皮经膀胱顺行插管和球囊扩张对膀胱出口梗阻患者有益。
