The cut to light procedure or antegrade and retrograde urethroscopy with endoscopic incision of obliterative urethral strictures is an accepted method of treating posterior urethral distraction injuries. We report long-term followup on 22 pediatric patients treated with this technique.
The records of all pediatric patients with a posterior urethral distraction injury treated from 1986 through 2006 were reviewed. The cut to light procedure was performed for obliterative strictures less than 1 cm via a cold knife or laser in 11 patients each. A urethral catheter was left in situ for 3 weeks. Patients were then followed a minimum of 2 years.
A total of 22 patients at a median age of 11 years (range 3 to 16) were treated. Followup revealed stricture recurrence in all patients. Median time to recurrence was 3 months after catheter removal (range 5 days to 1 year). Although intermittent catheterization to maintain patency was attempted in all patients, the development of impassable urethral strictures in 16 (73%) and complaints of chronic pain with catheterization in 4 (18%) led to end-to-end urethroplasty. Successful reconstruction with open surgery was achieved in 19 of 20 patients (95%). Two patients (9%) maintained urethral patency with intermittent catheterization.
In children with obliterative posterior urethral distraction injuries a cut to light procedure had a long-term success rate of 0%. All patients required daily intermittent catheterization (9%) or formal urethral reconstruction (91%) to maintain patency. We would strongly recommend against treating pediatric obliterative urethral strictures with a cut to light procedure.
尿道切开直视手术或顺行与逆行尿道镜检查并内镜下切开闭锁性尿道狭窄是治疗后尿道牵张损伤的一种公认方法。我们报告了采用该技术治疗的22例儿科患者的长期随访结果。
回顾了1986年至2006年期间所有接受后尿道牵张损伤治疗的儿科患者的记录。对于长度小于1cm的闭锁性狭窄,分别对11例患者采用冷刀或激光进行尿道切开直视手术。留置尿道导管3周。然后对患者进行至少2年的随访。
共治疗22例患者,中位年龄11岁(范围3至16岁)。随访发现所有患者均出现狭窄复发。复发的中位时间为拔除导管后3个月(范围5天至1年)。尽管所有患者均尝试间歇性导尿以维持通畅,但16例(73%)出现无法通过的尿道狭窄,4例(18%)出现导尿时慢性疼痛,最终均进行了端端尿道成形术。20例患者中有19例(95%)通过开放手术成功重建。2例患者(9%)通过间歇性导尿维持尿道通畅。
对于患有闭锁性后尿道牵张损伤的儿童,尿道切开直视手术的长期成功率为0%。所有患者都需要每日进行间歇性导尿(9%)或正式的尿道重建(91%)以维持通畅。我们强烈建议不要采用尿道切开直视手术治疗儿科闭锁性尿道狭窄。
