目的：探讨应用回肠代输尿管术治疗医源性长段输尿管损伤的疗效。方法：总结自2010年8月至2014年9月期间接受回肠代输尿管术的9例医源性长段输尿管损伤患者的临床资料,其中男性3例,女性6例,中位年龄40岁。中位输尿管损伤长度为20 cm,范...目的：探讨应用回肠代输尿管术治疗医源性长段输尿管损伤的疗效。方法：总结自2010年8月至2014年9月期间接受回肠代输尿管术的9例医源性长段输尿管损伤患者的临床资料,其中男性3例,女性6例,中位年龄40岁。中位输尿管损伤长度为20 cm,范围13~25 cm。常见医源性输尿管损伤原因为泌尿外科手术6例,妇产科手术2例,普外科手术1例。9例患者均行回肠代输尿管术,术后留置输尿管内双J管1~2个月。对所有入组患者进行门诊及电话随访,了解其并发症及术后肾功能情况,采用Clavien并发症分级系统对术后并发症进行分级。结果：9例手术均顺利完成,手术时间为203~394 min,平均（278.1±68.8）min,估计出血量为10~1 000 m L（中位数200 m L）,平均住院时间为（16.8±7.5）d。4例（44.4%）患者发生术后并发症,均为ClavienⅠ~Ⅱ级轻微并发症,其中不全肠梗阻3例（33.3%）,近端吻合口漏1例（11.1%）。中位随访时间11个月,8例（88.9%）患者术后肌酐水平较术前相比有所改善或稳定。随访过程中3例（33.3%）患者出现轻度肾积水,但无明显症状亦不需特殊处理;1例（11.1%）患者发生短期泌尿系感染,需口服抗生素治疗;未发现代谢性并发症发生。结论：回肠代输尿管术是一种可选择的尿路重建方式,尤其对难治性医源性长段输尿管损伤的治疗效果满意,其远期临床疗效仍需进一步观察。展开更多
