儿童泌尿系感染36例临床分析

Clinical Study on Children with Urinary Tract Infection

目的探讨儿童泌尿系感染（urn）的临床特点，为临床诊治提供参考。方法对36例泌尿系感染患者的临床表现、辅助检查结果、治疗等临床资料进行回顾分析。结果本组中有发热、呕吐、烦躁、哭闹、易激惹等非特异表现者13例（36．11％）;有明显尿路刺激症状15例（41．67％）;发热、腹痛者3例（8．33％）;单纯腹痛者2例（5．56％）；尿液异味者3例（8．33％）。离心尿沉渣镜检白细胞均〉5个／Hp，28例进行了尿培养及菌落计数，阳性19例（67．86％），余9例阴性（32．14％），应用抗生素前、后留取标本培养阳性率差异有显著性。影像学检查发现泌尿系畸形9例（占25％）。结论儿童UTI的症状和体征有非特异性，尿液检查能为早期诊断提供依据；一旦明确UTI的诊断，应注意寻找潜在的病因，UTI与原发或继发泌尿系畸形密切相关。此外，有必要建立严格的随诊追踪制度，以进一步发现UTI患者潜在的一些畸形，以及预防和治疗反复UTI，防止肾脏的进一步损害。

Objective To investigate the clinical features of 36 children with urinary tract infection（ UTI ）. Methods Clinical situation, auxiliary examination, and remedy of the 36 children with UTI was retrospectively analyzed. Results 13 of the 36 children with UTI presented with non-specific clinical manifestation, such as fever, vomiting, restlessness, crying, and irritability;l 5 with the clear signs of UTI, including increased frequency of urination, dysuria, and urgency;3 with fever and stomachache ;2 only with stomachache ;3 with strong-smelling urine.

Culture＇s positive rate of the patients who had not used antibiotics before the test was higher than those who had used. Urinary tract abnormalities detected by iconography were found in 9 children. Conclusion Signs and symptoms of children with UTI were non-specificity, early diagnosis of UTI were based on the urine tests. After UTI was diagnosed, potential etiological factors of UTI must he researched, UTI closely correlated to urinary tract abnormalities. Strictly follow-up of the children with UTI can help us find the potential abnormalities, prevent and cure the relapse of UTI, so as to prevent the kidney from further damage.
