Using the hydrophilic Terumo Glidewire we developed a less traumatic, yet effective alternative method to filiforms and followers for cases of urethral obstruction.
The initial step and cornerstone of our method is the passage of the Glidewire per urethra in a manner similar to a filiform. After the appropriate intravesical location of the Glidewire is confirmed using a ureteral catheter, it is exchanged for a standard polytetrafluoroethylene (Teflon) coated guide wire. Urethral dilation and/or catheter placement is then performed.
This technique was successful in 19 of 20 attempts, several of which followed unsuccessful passage of filliform catheters. Urethral obstruction due to strictures, bladder neck contractures and benign prostatic hyperplasia in our group was treated effectively. Furthermore, no complications occurred due to the technique.
The Glidewire method is safe and effective for treating most cases of urethral obstruction. Therefore, we recommend this technique over standard filiforms and followers when flexible or rigid cystourethroscopy is not immediately available.
我们利用亲水的泰尔茂导丝,针对尿道梗阻病例开发了一种创伤较小但有效的替代丝状探子和导尿管探子的方法。
我们方法的初始步骤及基础是,以类似于丝状探子的方式经尿道插入导丝。使用输尿管导管确认导丝在膀胱内的合适位置后,将其换成标准的聚四氟乙烯(特氟龙)涂层导丝。然后进行尿道扩张和/或放置导管。
该技术在20次尝试中有19次成功,其中几次是在丝状导管插入失败后进行的。我们组中由狭窄、膀胱颈挛缩和良性前列腺增生导致的尿道梗阻得到了有效治疗。此外,该技术未引发并发症。
导丝法治疗大多数尿道梗阻病例安全有效。因此,当无法立即进行软性或硬性膀胱尿道镜检查时,我们推荐该技术而非标准的丝状探子和导尿管探子。
