摘要

金属输尿管支架越来越多地用于治疗恶性输尿管梗阻,这是泌尿外科和其他恶性肿瘤中常见的并发症。然而,对这些支架相关并发症的评估有限,包括使用磁共振成像(MRI)可能引起的并发症。虽然大多数设备在名义上被认为是“mri安全的”,但它们对成像质量的影响尚未在临床试验中进行评估,而且在我们的实践中,一些输尿管支架(特别是Teleflex rsch DD肿瘤支架)遇到了明显的伪影,影响了图像质量和诊断的确定性。

Effect of Metallic Ureteric Stents on Magnetic Resonance Imaging: Implications for Malignant Ureteral Obstruction
Metallic ureteric stents are increasingly used for the management of malignant ureteric obstruction, a commonly encountered complication in urological and other malignancies. However, there has been limited evaluation of complications associated with these stents, including those that might arise from the use of magnetic resonance imaging (MRI). While most devices are deemed nominally “MRI-safe,” their implication on the quality of imaging produced has not been evaluated in clinical trials, and in our practice, significant artefact has been encountered with some ureteric stents—specifically, the Teleflex Rüsch DD tumour stent—compromising image quality and diagnostic certainty.
