Although double-J stents (DJS) are used to reduce complications following extracorporeal shock wave lithotripsy (ESWL), there has recently been a tendency to limit their use because of complications. We retrospectively reviewed 351 patients with renal stones larger than 30 mm to determine the effectiveness and the complications of DJS. While DJS were inserted prior to ESWL in 85 patients, 266 patients were treated without. The stone-free rate in the stented group was not significantly different from the non-stented group (31 and 30%). While the auxiliary treatment rate for the steinstrasse was 15% in the stented group, it was 18% in the non-stented group. Additionally, 4 of the stented patients (5%) were treated endoscopically because of encrustation or migration of the stent. Half of the patients in the stented group complained of mild bladder discomfort and disturbances which were relieved after removal of the DJS. We believe that DJS neither enhance stone passage nor reduce complications following ESWL, and therefore suggest their use only under certain conditions such as patients with solitary kidneys.
尽管双J管（DJS）用于减少体外冲击波碎石术（ESWL）后的并发症，但最近由于并发症的原因，其使用有受限的趋势。我们回顾性分析了351例肾结石大于30mm的患者，以确定双J管的有效性和并发症。85例患者在ESWL前插入了双J管，266例患者未使用双J管进行治疗。置入双J管组的结石清除率与未置入组无显著差异（分别为31%和30%）。双J管组的石街辅助治疗率为15%，未置入组为18%。此外，4例置入双J管的患者（5%）因支架结壳或移位接受了内镜治疗。置入双J管组一半的患者抱怨有轻度膀胱不适和干扰，在取出双J管后症状缓解。我们认为双J管既不能促进结石排出，也不能减少ESWL后的并发症，因此建议仅在某些情况下使用，如孤立肾患者。
