Objective To investigate the long-term relapse rate of urolithiasis after ESWL surgery and the measures to prevent the recurrence of stones. Regular follow-up of 128 cases of upper urinary tract stones without esophageal residual stones treated with ESWL in the past 10 years was conducted. Methods The ESWL treatment was reviewed every six months. KUB, BUS, urinalysis and renal function tests were performed. Patients with pain or suspicion of recurrence of stones were reviewed. The follow-up time was 566 years on average. Results The total recurrence rate was 15 6% (189/128). The recurrence rates at 1, 3 and 5 years were 4%, 94% and 118% respectively. Most of the recurrent stones were found in the lower kidney, Multiple renal stones are more common. Conclusion ESWL is an ideal method for the treatment of upper urinary tract stones. The recurrence rate is low, emphasizing the importance of ESWL after drinking more water and insisting on the oral administration of Chinese and Western medicines to prevent the recurrence of stones.
