目的探讨输尿管支架管(双J管)放置术后体外冲击波碎石(ESWL)治疗肾结石的疗效。方法选择肾结石最大直径2cm以上病例共58例,双侧结石者选直径大于2cm任何一侧,随机分为两组,对照组单纯行ESWL,实验组于ESWL前置入双J管。观察两组疗效及并发症发生率有无差别。结果 ESWL成功治疗55例,实验组全部治疗成功且无并发症,对照组12例“石街”形成,改用其他方法治疗。结论输双J管放置术后ESWL治疗肾结石,可有效减少并发症的出现。
Objective To investigate the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of renal calculus after placement of ureteral stent (double J-tube). Methods A total of 58 cases with a maximum diameter of 2 cm or more were selected. Patients with bilateral stones larger than 2 cm in diameter were randomly divided into two groups. The control group received ESWL only. The experimental group was placed double J tube before ESWL. The two groups observed the incidence of complications and whether there is any difference. Results 55 cases were successfully treated with ESWL. All the patients in the experimental group were treated successfully without complications, and 12 cases in the control group were formed by Stone Street, and were treated by other methods. Conclusion The double-J tube placed after ESWL treatment of renal stones, can effectively reduce the incidence of complications.
