ureteral stents are used in managing various urological conditions. When these stents are left indwelling for a prolonged time, it results in complications like stent migration, fragmentation, and encrustation. The aim of this retrospective observational study is to analyse the incidence, risk factors, and morbidity associated with retained ureteral stents.
the retained/forgotten ureteral stents were defined as the stents with an indwelling period of more than six months. The records of all such patients from January 2010 to January 2020 were retrospectively reviewed. The primary reason for the placement of a stent, total indwelling time, the reason for prolonged indwelling time, and part(s) of the stent encrusted were retrospectively reviewed. Single/multistage endourological procedures were used to make the patients remove the retained stents and stone free. The type, number of procedures, and total number of sessions needed were noted.
data of 114 patients was reviewed retrospectively. Most patients presented with abdominal pain (62 patients, 54.4%), and dysuria (41 patients, 35.1%). An average of 1.7 sessions (range 1-4) were needed to make the patients' stent and stone free. During these sessions, single/multiple procedures (endoscopic/open/combined) were performed. Nine patients (7.9%) had permanent loss of renal unit function and who needed a nephrectomy. Poor compliance (45.6%), unawareness (35.1%), and misconception that the stent would last a lifetime (12.3%), were the most common reasons for retained ureteral stents. The incidence rate of retained stents fell from 1.1% to 0.5% after the "three steps" prevention check method was in-cooperated to ensure timely follow-up of the patients.
retained ureteral stents are a significant source of morbidity, which is avoidable by ensuring timely removal. Sincere efforts should be made to make patients aware of an indwelling foreign body. Prevention is the best strategy.
输尿管支架用于治疗各种泌尿科疾病。当这些支架被留置过长时间时，会导致支架迁移、碎裂和结壳等并发症。本回顾性观察研究旨在分析与留置输尿管支架相关的发生率、危险因素和发病率。
将留置/遗忘的输尿管支架定义为留置时间超过 6 个月的支架。回顾性分析 2010 年 1 月至 2020 年 1 月所有此类患者的记录。回顾分析支架放置的主要原因、总留置时间、留置时间延长的原因以及支架的哪部分结壳。采用单/多阶段内镜下手术使患者取出留置支架并达到无结石状态。记录所用的手术类型、数量和总次数。
回顾性分析了 114 例患者的数据。大多数患者表现为腹痛（62 例，54.4%）和尿痛（41 例，35.1%）。平均需要 1.7 次（1-4 次）治疗使患者的支架和结石清除。在这些治疗过程中，采用了单/多步手术（内镜/开放/联合）。9 例（7.9%）患者因永久性肾功能丧失而需要肾切除术。最常见的留置输尿管支架的原因是依从性差（45.6%）、不知情（35.1%）和错误地认为支架可以终身使用（12.3%）。在实施“三步”预防检查方法以确保及时对患者进行随访后，留置支架的发生率从 1.1%降至 0.5%。
留置输尿管支架是发病率的一个重要来源，可以通过确保及时取出支架来避免。应努力使患者意识到留置的异物。预防是最好的策略。
