Impassable urethral strictures: percutaneous transvesical catheterization and balloon dilatation.

Abstract

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.
