Many complications due to double j (DJ) stent placement have been reported. DJ stent knotting is a rare complication, with only a few cases reported in the literature. We presented a case of DJ stent knotting and reviewed the literature regarding this complication. We reported a 20-year-old man with a history of cystinuria and ureteral stone managed with retrograde ureteroscopy and holmium laser three months ago. The patient comes for DJ stent removal. Firstly, we tried to remove the DJ stent via the cystoscopic procedure, which failed. A fluoroscopic image revealed a knotted DJ stent lodged at the ureteropelvic junction and was removed via holmium laser ureteroscopic procedure without complications. In conclusion, when cystoscopic procedure with simple traction fails to remove DJ stents, multimodality urological procedures such as holmium laser should be tried, especially in patients with urolithiasis predisposing factors.
许多与双 J（DJ）支架放置相关的并发症已有报道。DJ 支架打结是一种罕见的并发症，文献中仅报道了少数几例。我们报告了 1 例 DJ 支架打结的病例，并对该并发症的文献进行了回顾。我们报告了 1 例 20 岁男性，既往有胱氨酸尿症和输尿管结石病史，3 个月前接受逆行输尿管镜检查和钬激光治疗。该患者来拔除 DJ 支架。首先，我们尝试通过膀胱镜手术取出 DJ 支架，但失败了。X 光片显示 DJ 支架在输尿管肾盂连接部打结，并通过钬激光输尿管镜手术取出，无并发症。总之，当膀胱镜手术单纯牵引不能取出 DJ 支架时，应尝试使用多模态泌尿外科手术，如钬激光，特别是在有尿路结石易患因素的患者中。
