To describe a simple technique that can be used to manage an unexpected mildly to moderately (<10 mm) encrusted ureteric stent with consummate ease when time, equipment, or experience are unavailable.
We present a series of 5 patients with impacted ureteric stents that were difficult to remove owing to presumed encrustation of the upper end. The indwelling time for the stent ranged from 8 to 16 weeks. All 5 patients were managed by insertion of a second ureteric stent alongside the original one.
The encrusted stents were successfully retrieved in all 5 patients at a subsequent visit after the insertion of the second stent, without the need for further specialist equipment or expertise.
Insertion of a second stent next to an unyielding, encrusted ureteric stent is a safe, simple, and effective technique to aid in its retrieval. We propose that it should be considered in select patients where encrustation is unexpected and an experienced endourologist is unavailable.
当时间、设备或经验不允许时，描述一种简单的技术，可用于轻松处理意外出现的轻度至中度（<10mm）包埋输尿管支架（严重程度为<10mm）。
我们介绍了 5 例因推测上端结壳而难以取出的嵌顿输尿管支架患者。支架留置时间为 8 至 16 周。所有 5 例患者均通过在原始支架旁插入第二条输尿管支架进行处理。
在插入第二条支架后的后续就诊中，所有 5 例患者的结壳支架均成功取出，无需进一步使用专科设备或专业知识。
在预料之外的结壳和缺乏有经验的腔内泌尿外科医生的情况下，在难以取出的、包埋的输尿管支架旁插入第二条支架是一种安全、简单且有效的取出方法。我们建议在有经验的腔内泌尿外科医生不可用时，应考虑将其应用于特定患者。
