目的:探讨外伤性后尿道闭锁或狭窄术后U形支架引流管拔除时机、方法。方法:对63例后尿道闭锁或狭 窄病人置“U”形支架管1～3个月,采用留置丝线法拔管,观察拔管后病人排尿情况,排尿期膀胱尿道造影以了解后 尿道情况。结果:一周内排尿通畅47例(75%)16例(25%)再次置管处理。“U”形支架管拔管时在尿道内保留丝 线,利于后期处理。结论:“U”形支架管在外伤性后尿道闭锁或狭窄手术后有换管简单,可带管排尿,能很好地冲洗 分泌物等优点。
Objective: To investigate the timing and method of U-stent drainage after traumatic posterior urethral atresia or stenosis. Methods: Sixty-three patients with posterior urethral atresia or stenosis were treated with “U” shaped stent for 1 to 3 months. Extubation was performed with indwelling silk thread. The excretion of patients after extubation and the cysto-urethra during voiding were observed to understand the situation of the posterior urethra. Results: In one week, 47 cases (75%) had urinary patency and 16 cases (25%) were re-catheterized. U-shaped stent tube extubation tube retained in the urethra, which will help post-treatment. Conclusion: The U-shaped stent has the advantages of easy tube change after catheterization or stenosis of traumatic posterior urethra, which can take the tube to urinate and wash the secretions well.
