Clinical Assessment of Visual Internal Urethrotomy as Primary Treatment of Urethral Stricture / 대한비뇨기과학회지

PURPOSE: We describe clinical assessment of visual internal urethrotomy (VIU) as primary treatment modality in 69 men who presented with complete or partial obstructed urethral stricture. MATERIALS AND METHODS: The 63 patients with partial obstructed urethral stricture were treated by typical VIU. The 6 men with complete obstructed urethral stricture were treated by VIU using sound passed through previously placed suprapubic tract as guide. RESULTS: The procedure was completed successfully in 57 of the 63 men with partial obstructed (90.5%) and 3 of 6 patients with complete obstructed urethral stricture (50%). CONCLUSIONS: VIU is a safe and effective as primary treatment plan when urethral stricture is partial obstructed and the impassable urethral segment is shorter than 1.0cm.

Treatment of Urethral Obstruction after Wallstent Implantation in Traumatic Urethral Stricture / 대한비뇨기과학회지

Endoscopic intraluminal implantation of a self expandable stent has been increasing in patients with recurrent urethral strictures because of its simple and relative safe technique. There has been a few reports concerning luminal obstruction after implantation of Wallstent. We have experienced 4 cases of urethral obstruction after variable period of Wallstent implantation in the treatment of traumatic urethral stricture. Herein the methods for treatment of urethral obstruction are discussed. The patients were managed with two different types of treatment. The first one was transurethral resection of granulation tissue inside Wallstent. The other is reinsertion of Wallstent inside the first one after transluminal resection of granulation tissue in patients with urethral obstruction occurring within 5 months after Wallstent implantation. Retrograde urethrography and urethroscopy after 3 months have demonstrated patency of urethra and epithelial covering of the implant. Our experience shows that in all 4 patients with traumatic urethral stricture have developed variable degrees of urethral obstruction after a variable period of wallstent implantation. Therefore, we consider that our method is one of the alternatives to treat urethral obstruction after wallstent implantation in patients with traumatic urethral stricture.
