Urinary Tract Infections (UTIs) due to ureteral catheters has been frequently seen. The risk factors of this include both timing and those of the female gender. However, the association of Acute Pyelonephritis (APN) with use of ureteral DJ stents has rarely been investigated.
This study enrolled a total of 6,459 patients who were being treated with a ureteral catheter over a 10 year period from the nationwide database of Taiwan's National Health Insurance Bureau. From these subjects, episodes of APN were found in a total of 500 patients. Additionally, 2,000 patients without APN were randomly enrolled as a control group in order to analyze the associated factors.
The results indicate that the percentage of those with regards gender, age, duration of implantation, ureteral stent type, hypertension, T2DM, presence of urinary tract infection, benign prostate hyperplasia and pregnancy status were significantly statistically higher in APN patients than non-APN patients. APN did not associate with the use of antibiotics, urolithiasis, chronic kidney disease, malignancy, or uric acid stone in patients with a ureteral catheter.
In conclusion, patients with a ureteral catheter associated with APN should be given close attention with regards to the above risk factors. Early removal of the catheter is the best policy for the prevention of APN.
留置输尿管导管引起的尿路感染（UTI）较为常见。其危险因素包括留置时间和女性性别。然而，急性肾盂肾炎（APN）与输尿管 DJ 支架使用之间的关联很少被研究。
本研究共纳入了 6459 例在过去 10 年期间因输尿管导管治疗而在台湾国家健康保险局全国数据库中接受治疗的患者。在这些患者中，共发现了 500 例 APN 发作。此外，随机招募了 2000 例无 APN 的患者作为对照组，以分析相关因素。
结果表明，与非 APN 患者相比，APN 患者的性别、年龄、植入时间、输尿管支架类型、高血压、T2DM、尿路感染、良性前列腺增生和妊娠状态的百分比显著更高。APN 与抗生素使用、尿路结石、慢性肾脏病、恶性肿瘤或尿酸结石无关。
总之，应密切关注留置输尿管导管并发 APN 的患者的上述危险因素。早期移除导管是预防 APN 的最佳策略。
