目的：探讨体外冲击碎石术（ ESWL）治疗肾结石前留置双J管的临床适应证及其必要性。方法按病例纳入标准将160例肾结石患者随机分成两组，行体外冲击波碎石术， A组（80例）治疗前留置双 J管， B 组（80例）治疗前未留置双J管，术后随访1～3月，比较两组之间的结石清除率及其并发症。结果A组中9人、B组中6人有＞5mm的结石碎片残留，需二期碎石治疗；3月后结石清除率分别为A组88％，B组91％。术后1～2天两组间肋腹部疼痛，恶心呕吐，短暂性血尿、镇痛剂的使用例数没有显著性差异，随访3月均未出现输尿管狭窄并发症。结论对于直径在1～2cm内的肾结石，ESWL治疗前留置双J管并不利于结石的排出，因此不需要常规术前留置双 J管。

Objective To assess the necessity for routine ureteral stenting before extracorporeal shock Wave lithotripsy ( ESWL) for renal calculi .Methods A total of 160 patients with renal calculi amenable to ES-WL were randomized divided into group A ( stented group , n =80 ) or group B ( unstented group , n =80 ) . The stone clearance rate and its complications were compared between the two groups .Results 9 patients in group A,6 patients in group B had >5 mm residual fragments..In these patients second ESWL session was necessary.Three months stone-free rate was 88%in group A and 91%in group B, respectively.There was no statistical difference in flank or abdominal pain , nausea, vomiting, transient hematuria, temperature or use of analgesics on the first and second day after ESWL in the stented or unstented group .During 3 months after ES-WL, there was no anatomical ureteral narrowing happened in both groups .Conclusion The use of double-J stents prior to ESWL treatment is not necessity for renal calculi .
