Abstract Objective To study the clinical application value of CTthrough the use of non-enhanced spiral CT (non-contrast helical computerized tomography (NCHCT)) for determination of CT values of calculi combined with the efficacy of ureteral calculus ESWL. Methods Seventy-nine patients with ureteral calculi at length between 0.6-1.5 cm, underwent non-enhanced spiral CT examination and determination of the CT values of the stones. They were divided into the average CT value <750 HU group and the average CTvalue> 750 HU group. After ESWL, the stone clearance rate and efficiency were observed in the two groups, and the basic characteristics between the two groups and the number of lithotripsy and effect were analyzed. Results The CT value and stone > 750 HU group, compared with <750 HU group needed less number of lithotripsy and high stone-free rate; the difference was statistically significant between the two groups (P< 0.05). Conclusions NCHCT stone average CT value can effectively predict ureteral calculi ESWL curative effect. Stone CT value <750 HU is easy to be broken to pieces, with high stone clearance rate, should employ ESWL as first choice, where as CT value > 750 HU with low stone-free rate, should consider first the endoscopic lithotripsy or open surgery.
