| 目的 分析尿路结石与尿路感染的相关性。方法 选择2010年2月至2013年10月唐山市工人医院收治的300例尿路结石患者，检测尿常规、中段尿阳性、术中结石附近棉拭子蘸液、尿路结石、术后尿路感染等情况，并分析感染性结石与非感染性结石的主要成分。结果 300例中发现感染性结石96例（32%），菌分离培养表明主要为大肠埃希菌（35例，36.5%）、表皮葡萄球菌（28例，29.2%）、奇异变形杆菌（15例，15.6%）；感染性结石组患者尿常规检查异常、中段尿阳性、术中棉拭子阳性和尿路感染的发生率均显著高于非感染性结石组，差异均有统计学意义（χ2＝8.203、73.99、178.9、24.26，P<0.05）；感染性结石组中六水磷酸镁铵、碳酸磷灰石和羟基磷灰石结石的发生率显著高于非感染性结石组，而草酸钙结石和尿酸结石的发生率显著低于非感染性结石组，差异均有统计学意义（χ2＝167.6、21.00、8.586、73.17、48.79，P<0.05）。结论 泌尿系统细菌感染可引起尿路结石，而后者亦会引起泌尿系统的进一步感染。尿路结石患者应做细菌培养检测，术后亦应避免泌尿系统感染。 |

| Objective To explore the correlation of urinary stones and urinary tract infections. Methods 300 cases with urinary tract stones received in our hospital from Feb. 2010 to Oct. 2013 were chosen as study samples. Urine routine index，situation of urine positivity and urinary tract infection after surgery were analyzed while，intraoperative cotton swabs were tested after being dipped in liquid near stones. Main components of stones in non-infected and infected stone group were analyzed and compared. Data on urolithiasis was collected. Results 96 infected stones were found in 300 patients，accounting for 32%，which including 35 cases of E. coli（36.5%), 28 cases of Staphylococcus epidermidis（29.2%), and 15 cases of Proteus mirabilis（15.6%). Numbers of urine abnormalities，urine positivities，positive intraoperative cotton swabs and urinary tract infections in patients in the group with infected stones，were significantly higher than in the group without infected stones and the differences were statistically significant（χ2＝8.203, 73.99, 178.9, 24.26, P<0.05). The incidence rates of hexahydrate magnesium ammonium phosphate， carbonate apatite and hydroxyapatite stones in the group with infected stones were significantly higher than those in the non-infected-rock group while the incidence rates of calcium oxalate and uric acid stones were found significantly lower than those in the non-infected-stone group，with differences statistically significant（χ2＝167.6, 21.00, 8.586, 73.17, 48.79, P<0.05). Conclusion Bacteria could cause urinary tract stones, and infected stones were always associated with urinary tract infections. Bacteria detection inpatients with urinary calculi was particularly important to avoid the urinary tract infections. |
