目的 分析小儿上尿路感染的临床特征及探讨尿路感染的定位方法。方法 对收治住院的 45例上尿路感染患儿进行回顾性分析。结果 发热 40例占 89% ,45例尿培养均阳性 ,其中大肠杆菌占 41 7% ,其它细菌占 5 8 3 %。B超在描述尿路积水及畸形方面与静脉肾盂造影 (IVP)结果相接近 ,放射性99m锝 -二巯基丁二酸肾静态显像 (DMSA)检查对肾实质感染定位敏感度高 ,排泄性膀胱造影 15例均有不同程度膀胱输尿管返流(VUR)。结论 小婴儿首次尿路感染就要及早定位、全面评价 ,根据DMSA以及B超检查结果 ,选择进行排泄性膀胱造影 ,以尽早发现VUR ,防止肾功能损害。
Objective To analyze the clinical features of children with upper urinary tract infection and to explore the method of locating urinary tract infection. Methods 45 cases of upper urinary tract infection admitted to hospital were retrospectively analyzed. Results 40 cases of fever accounted for 89%, 45 cases of urine culture were positive, including 41.7% of E. coli, other bacteria accounted for 58.3%. B ultrasound in the description of urinary tract water and deformity and intravenous pyelography (IVP) results are close to radioactive 99m technetium-dimercaptosuccinate renal static imaging (DMSA) examination of renal parenchymal infection location sensitivity, excretion Bladder ureter in 15 cases have varying degrees of vesicoureteral reflux (VUR). Conclusion The first urinary tract infection in infants should be located as soon as possible, and comprehensively evaluated. According to the results of DMSA and B-ultrasound, excretion cystography was selected to detect VUR early to prevent renal dysfunction.
