The impact factors analysis in using extracorporeal shock wave lithotripsy for patients with ureteral calculi / 中国综合临床

ABSTRACT

Objective To summarize the impact factors of extracorporeal shock wave lithotripsy (ESWL) in ureteral calculi patients.Methods The data of 287 patients with ureteral calculi from January 2010 to December 2012 in the Aerospace General Hospital of Beijing who received the ESWL were retrospectively analyzed.The relationship between ESWL' s effect and patients' gender, age, the stone' s size, the stone's location, the length of the course and the stone bed' s polyps hyperplasia was analyzed.Results The Partial correlation course and chi-square test showed that, there was statistically significant difference between the ESWL treatment effect and patient' s age, patient' s length of the disease course and patient' s stone size (P＜0.01).The value of OR between patient' s age and ESWL treatment effect was 1.905, showed that with the age of the patients increased every 10 years, the success rate of ESWL was reduced by 1.905 times.The value of OR between the patient' s length of the disease course and ESWL treatment effect was 2.809,indicated that with the duration of the course of prolonged every 1 month, the ESWL success rate decreased by 2.809 times.The value of OR between stone size and ESWL effect was 2.277, showed that the ratio between the stone diameter of 1.1-2.0 cm and 0.6-1.0 cm, the ESWL success rate reduced by 2.277 times.For the surgery patients who were failure to ESWL treatment,we found that there has statistical significance between the patients' length of disease course and stone bed' s polyps hyperplasia(P＜0.01), but the relationship between the stone bed' s polyps hyperplasia and the gender, the age, the stone' s position, the stone ' s size had no statistical significance (P ＞ 0.05) .Conclusion The patient ' s age, the length of the disease course, the stone ' s size and stone' s position are significantly affect to the effect of ESWL.There have closely relationship between the length of the disease course and the stone bed' s polyps hyperplasia, which is the reason why the longer length of the course, the worse the ESWL' s effect.This has very important instructed meaning for anticipating the treatment effect by the comprehensive evaluation of the patients before ESWL treatment.
