摘要
目的探讨肾积水程度对输尿管结石(UC)患者冲击波碎石术(SWL)排石成功率的影响。方法回顾性选择2013年1月值2017年5月来本院接受SWL术治疗的UC患者420例。根据患者术后3个月排石成功与否分为排石成功组(310例)和排石失败组(110例)。比较两组患者在临床特征方面的差异,并比较不同肾积水程度患者临床特征方面的差异。应用单因素、多因素非条件Logistic回归分析探讨影响UC患者SWL术排石成功的危险性因素。结果排石成功组在结石异质性指数方面显著高于排石失败组(P<0.05),在年龄、结石直径、结石密度、肾积水严重程度方面显著低于排石失败组(P<0.05)。不同肾积水程度患者在性别、结石部位、结石直径、结石密度、一次排石成功例数方面差异显著(P<0.05)。单因素、多因素Logistic回归分析显示,结石直径≥10.00mm、结石密度≥700.00HU、结石异质性指数≤235.00HU、肾积水程度≥3级会增加UC患者SWL术排石失败的风险(P<0.05)。结论术前3级和4级程度的肾积水不利于UC患者SWL术排石效果。
Objective To investigate the effect of the degree of hydronephrosis on the success rate of shock wave lithotripsy (SWL) in patients with ureteral calculi (UC). Methods From January 2013 to May 2017, 420 patients with UC received SWL in our hospital were selected as study subjects. The patients were divided into the successful group (n=310) and the failure group (n=110) according to success of stone removal 3 months after the operation. The differences in clinical characteristics between the two groups were compared, and the differences of clinical features in patients with different hydronephrosis groups were compared. Univariate and multivariate logistic regression analysis were used to investigate the risk factors of success of SWL in UC patients. Results The stone heterogeneity index in successful group was significantly higher than in failure group (P<0.05), the age, stone diameter, stone density and severity of hydronephrosis were significantly lower than those of failure group (P<0.05). The patients with different degree of hydronephrosis had significant differences in sex, stone site, stone diameter, stone density, and one-session success (P<0.05). Univariate and multivariate logistic regression analysis showed that stone diameter≥10.00 mm, stone density≥700.00 HU, stone heterogeneity index≤235.00 HU, degree of hydronephrosis≥3 grade could increase risk of failure of SWL surgery in UC patients (P<0.05). Conclusions The 3 and 4 levels of renal hydronephrosis before operation are not beneficial to the effect of SWL in UC patients.
