Urethral catheterization can often be technically demanding due to the presence of obstructing segments within the urethra. Conventional methods attempting to restore urethral patency often are unsuccessful and traumatize the urethral lumen.
We present an innovative technique by using a hydrophilic guidewire and a hydrophilic ureteral access sheath for the 'first-line' catheterization and management of 'difficult' urethral strictures. We used this technique in 10 extremely difficult cases of strictures present in all the urethral segments.
The dilation was successful and atraumatic in all the cases due to the hydrophilic nature of the access sheath. In all patients, larger sizes of urethral catheters were gradually inserted within the next couple of days.
We propose 'access sheath'-assisted urethral dilatation as a safe and simple alternative for the 'first-line' catheterization and, possibly, management of 'difficult' urethral strictures.
由于尿道内存在梗阻段，导尿术在技术上往往要求较高。试图恢复尿道通畅的传统方法常常不成功，且会损伤尿道腔。
我们介绍一种创新技术，即使用亲水导丝和亲水输尿管通路鞘进行“一线”导尿及处理“困难”尿道狭窄。我们将此技术应用于10例尿道各段均存在极其困难狭窄的病例。
由于通路鞘的亲水特性，所有病例的扩张均成功且无创伤。在所有患者中，接下来的几天内逐渐插入了更大尺寸的尿道导管。
我们提出“通路鞘”辅助尿道扩张作为“一线”导尿以及可能处理“困难”尿道狭窄的一种安全且简单的替代方法。
