摘要
目的探讨不同频率体外冲击波碎石术(extracorporeal shock wave lithotripsy,ESWL)治疗输尿管单发结石的疗效和安全性。方法行ESWL治疗的输尿管单发结石患者268例,根据ESWL冲击波频率分为低频组142例和高频组126例,分别应用频率60、90Hz冲击波进行治疗。术后随访3个月,比较2组术后1、4周及3个月排石率、排净率及并发症发生率。结果低频组术后4周、3个月结石排净率(69.0%、85.9%)高于高频组(56.3%、75.4%)(P<0.05),术后疼痛或肾绞痛发生率(2.8%)低于高频组(8.7%)(P<0.05)。结论 60 Hz频率冲击波可提高ESWL治疗输尿管单发结石术后结石排净率,降低疼痛或肾绞痛发生率。
Objective To explore the effect and safety of extracorporeal shock wave lithotripsy （ESWL） with different shock wave frequency in the treatment of ureteral solitary calculi. Methods A total of 268 cases of ureteral calculi undergoing ESWL were divided into low frequency group （n=142, 60 Hz） and high frequency group （n= 126, 90 Hz） according to the ESWL shock wave frequency. All cases were followed up for 3 months after treatment. The stone expulsion rate, stone-free rate and complication incidence were observed in postoperative 1 week, 4 weeks and 3 months between two groups. Results The stone-free rates in 4 weeks and 3 months after operation （69.0%, 85.9%） in low frequency group were significantly higher than those in high frequency group （56. 3%, 75. 4%） （P〈0.05）. The incidence of postoperative pain and renal colic was significantly lower in low frequency group （2.8%） than that in high frequency group （8.7%） （P〈0.05）. Conclusion The shock wave frequency of 60 Hz can improve the stone-free rate of ESWL for solitary ureteral calculi and reduce the incidence of postoperative pain and renal colic.
