Ureteral stents are widely used. If ureteral stents remain in place for extended periods, the probability of migration and stone formation increases substantially. However, a 29-year-old ureteral stent that was placed and did not develop calculus is rare. We reported a 45-year-old man admitted with pain in the left side of his waist and abdomen for more than 10 years. He underwent a ureterotomy 29 years prior to admission for left ureteral calculi, and a ureteral stent was placed postoperatively to prevent ureteral strictures. The ureteral stent was not removed in the hospital due to poor compliance on the part of the patient. This left ureteral stent was not visible on computed tomography (CT) and plain films. On ureteroscopy or flexible ureteroscopy, no new calculus was found in the left ureter and kidney. No calculus was found in the stent that is usually easily removed with calculus-removing forceps. This phenomenon is rare, and it highlights the importance of follow-up.
输尿管支架被广泛使用。如果输尿管支架长时间留置，其移位和结石形成的概率会大幅增加。然而，一枚放置了29年且未形成结石的输尿管支架实属罕见。我们报告了一名45岁男性，因左侧腰腹部疼痛10余年入院。他在入院前29年因左侧输尿管结石接受了输尿管切开术，术后放置了输尿管支架以预防输尿管狭窄。由于患者依从性差，输尿管支架未在医院取出。这枚左侧输尿管支架在计算机断层扫描（CT）和平片上均不可见。在输尿管镜检查或软性输尿管镜检查中，左侧输尿管和肾脏未发现新的结石。在通常用取石钳很容易取出结石的支架中也未发现结石。这种现象很罕见，它凸显了随访的重要性。
