The aim of the study is to comprehensively report on a single tertiary referral center experience with the use of ureteric stents, assess complication burden and determine risk factors to further inform institutional practice.
The retrospectively analyzed cohorts includes 529 patients treated over a 12 months period. Data regarding details of the index pathology, stent characteristics and complications were collected retrospectively.
Most stents (58.9%) were used in the context of stone surgery. Stent encrustation occurred in 14.5% of patients and sepsis in 4.3%. There was a statistically significant difference between the complications of the stents removed after 90 days and the rest of the cohort. Infectious complications were more frequent in diabetic patients and in patients with chronic renal impairment. At our institution, we managed to avoid forgotten stents and catastrophic complications.
Stent complications are the complex outcome of interplay between the foreign body and the collecting system environment, influenced by the nature and timing of surgery. Longer stent dwelling times are associated with increased complications rates, especially in patients with significant comorbidities.
本研究旨在全面报告一家三级转诊中心使用输尿管支架的经验，评估并发症负担并确定风险因素，以进一步指导机构实践。
回顾性分析的队列包括在12个月期间接受治疗的529例患者。回顾性收集有关索引病理学细节、支架特征和并发症的数据。
大多数支架（58.9%）用于结石手术。14.5%的患者发生支架结壳，4.3%的患者发生败血症。90天后取出的支架并发症与其余队列之间存在统计学显著差异。糖尿病患者和慢性肾功能损害患者的感染性并发症更为常见。在我们机构，我们成功避免了遗忘支架和灾难性并发症。
支架并发症是异物与集合系统环境相互作用的复杂结果，受手术性质和时机影响。较长的支架留置时间与并发症发生率增加相关，尤其是在有严重合并症的患者中。
