Observation of efficacy of ESWL in different period in management of ureteral stones

Abstract

Objective To compare the efficacy of the emergency ESWL within 24 hours after the onset of renal colic and elective ESWL at 5 ～ 14 days after the onset of renal colic in the treatment for ureteral stones.Methods 280 patients in the People's Hospital of Pingding,according to the wishes of patients with ureteral stones were admitted to our department for renal colic.All patients onset to treatment time 0.5 ～ 10h,They underwent emergency ESWL or elective ESWL with WD-ESWL Vi Guangdong Weida energy electromagnetic shock wave lithotripter.Success rate of fragmentation,stone-free rate after 2 weeks of operation,pain recurrence rate,and complications were evaluated.Results The success rate of fragmentation and the stone-free rate after 2 weeks of emergency ESWL were 97.18％ and 96.60％,respectively,which were higher than those(88.75％ and 87.61％,respectively)of elective ESWL(P ＜ 0.05).The postoperative pain recurrence rate of emergency ESWL(5.12％)was lower than that (10.24％)of elective ESWL(P ＜0.05).There was no difference of total complications between emergency ESWL (3.44％)and elective ESWL(2.98％)group(P ＞ 0.05).Conclusion Emergency ESWL is superior to selective ESWL and is the safe and effective method for the management of ureteral stones.
