输尿管结石肾绞痛期行体外冲击波碎石术并发肾内感染的探讨

Renal infection after extracorporeal shock wave lithotripsy to treat renal colic period of ureteral calculi

目的探讨输尿管结石患者行体外冲击波碎石术(extracorporeal shock wave lithotripsy,ESWL)并发肾内感染的相关因素。方法选择2006-06至2009-06于我院行ESWL的输尿管结石278例,根据行ESWL前是否有肾绞痛分为绞痛组128例及非绞痛组150例。对两组行ESWL后发生肾内感染的情况进行比较。结果绞痛组行ESWL后发生肾内感染率与非绞痛组比较,差异有统计学意义(P<0.01);绞痛组中、下段结石与上段及中段结石行ESWL后发生肾内感染率相比差异有统计学意义(P=0.02)。结论行ESWL前有肾绞痛的输尿管结石患者术后并发肾内感染率高。输尿管下段结石的肾绞痛患者行ESWL后发生肾内感染率较高。

Objective To study the factors of renal infection developed after extracorporeal shock wave lithotripsy（ESWL） to treat ureteral calculi. Methods 278 patients with ureteral calculi were received ESWL to treat ureteral calculi at this hospital from June 2006 to June 2009, including 128 patients with renal colic （experimental group） and 150 patients without it （control group）. The renal infection developed after ESWL was compared between the two groups. Results There was statistically significant difference in percentage of renal infection occurrence between the experimental group and the control group（ P 〈 0.00l ）. There was statistically significant difference between in percentage of renal infection occurrence between lower ureteral stone and upper or middle ureteral stone in experimental group （ P = 0.02）. Conclusions Patients with ureteral stones and renal colic before ESWL have high percentage of renal infection occurrence. Patients with lower ureteral stones and renal colic before ESWL have high percentage of renal infection occurrence.
