초록

목 적 : 선천성 및 첫 발열성 요로감염으로 진단시 발견된 수신증 환자들에서 임상적 특성에 따른 발열성 요로감염의 발생률을 확인하고자 하였다. 방 법 : 본 연구는 2000년부터 2009년까지 10년간 선천성 수신증으로 진단 받은 200명(군 1)과 첫 발열성 요로감염으로 진단 시 발견된 신장 초음파상 수신증으로 진단받은 252명(군 2)을 대상으로 하였다. 두 군에서 각각 임상적 특징, VUR의 유무, 수유방법, 그리고 선천성 수신증의 임상 경과에 따른 요로감염의 발생 빈도에 대해 알아보았다. 그리고, 그 결과들을 분석하였고, 두 군을 서로 비교하였다. 결 과 : 군 1과 군 2에서 요로감염의 발생률 및 재발률은 각각 10%, 16.7%이며, 요로감염의 연간 발생 빈도(episodes per person-years) 및 재발 빈도는 각각 0.028, 0.051였다. 군 2에서 군 1에 비해 VUR이 많았고(3% vs. 27%, P<0.05), 요로감염의 발생률이 높았다. 군 2에서만 VUR등급이 높을수록 요로감염의 발생률이 높았다(P=0.032). 군 1에서 SFU grade 4와 VUR grade 4-5에서 요로감염의 발생률은 각각 80%, 44.4%였다. 두 군 모두에서 모유 수유 환아들과 분유 수유 환아들 사이에 요로감염의 발생률은 차이가 없었다(P 1=0.274, P 2=0.4). 선천성 수신증의 호전 시기(<1 vs. 1-2 vs. >2 year-old vs. no resolution over 2 year-old)에 따른 요로감염의 발생률과 VUR의 유무는 유의한 차이가 없었다. 결 론 : 선천성 수신증 및 첫 발열성 요로감염으로 진단 시 발견된 수신증 환아에서 SFU grade 4 또는 VUR 4-5를 제외하고는 전반적인 요로감염의 발생률은 낮았다. 모유 수유는 급성 요로감염의 발생 예방에 효과가 없다.

Purpose : The aim of this study was to evaluate the incidence of febrile urinary tract infection (UTI) according to clinical characteristics in patients with congenital hydronephrosis (CH) and hydronephrotic patients first diagnosed with hydronephrosis during treatment of febrile UTII. Methods : In this study, 200 patients with congenital hydronephrosis were enrolled in group 1 and 252 patients first diagnosed with hydronephrosis during treatment of febrile UTI were enrolled in group 2. We counted the episodes of UTI in the two groups according to clinical characteristics, the presence of VUR, type of feeding, and clinical outcomes since 2000. And we compared those results between the two groups. and compared two groups as well. Results : The incidence of recurrent UTI was 10%, 0.028 per person-year in group 1 and 16.7%, 0.051 per person-year in group 2, respectively (P <0.05). Group 2 had more VUR (3% vs. 27%, P <0.05) and higher incidence of UTI than group 1. The incidence of UTI in patients with CH of Society of Fetal Urology (SFU) grade 4 or grade 4-5 VUR was 80% and 44.4%, respectively. No significant differences were found in incidence of UTI between BMF (breast milk feeding) and artificial milk feeding group in both groups (P 1=0.274, P 2=0.4). The time of resolution of CH had no correlation with either number of UTI episodes or the presence of VUR. Conclusion : The overall incidence of UTI is low in patients with CH as well as patients patients first diagnosed with hydronephrosis during treatment of febrile UTI except patients with SFU grade 4 or grade 4-5 VUR. BMF has no protective effect against UTI.
