Objective To analyze the clinical characteristics of renal abscess in children and provide suggestions for early diagnosis and treatment. Methods The clinical data including general information, laboratory data, imaging results, treatment and prognosis of 20 pediatric patients with renal abscess admitted to the Department of Nephrology, Capital Center for Children's Health Capital Medical University were analyzed retrospectively. Results A total of 8 males and 12 females were enrolled. The age of onset was 3.0 (0.8, 9.0) years. All cases had fever. Six cases presented with abdominal pain, 6 cases had poor appetite, 5 cases had vomiting and 5 acses urinary tract irritation symptoms. Laboratory data showed elevated white blood cells 20.4 (17.4,26.3)×109/L, C-reactive protein 126 (77, 154)mg/L, erythrocyte sedimentation rate 60 (41,73) mm/1 h in 20 cases and procalcitonin 4.7 (1.2,33.5)μg/L in 10 cases. Totally 18 cases had pyuria. Urine culture was positive in 8 cases. Enterococcus faecium and Pseudomonas aeruginosa was detected in 2 cases. Klebsiella pneumoniae was found in 1 case after performing blood culture. Renal abscess was confirmed in all cases by doing contrast-enhanced CT scan, while only 9 cases with abscesses were identified by using renal ultrasound. There were 14 cases with renal abscess formation confirmed at onset by performing magnetic resonance imaging. Nine cases were accompanied with congenital anomalies of the kidney and urinary tract. All cases received conservative medical treatment. Intravenous broad-spectrum antibiotics were administered for at 23 (14, 39)d initially, while the medication in 11 cases were upgraded to meropenem or imipenem. Oral antibiotics were continued for 23 (14, 28)d after discharge in all cases. Within 1 year of follow-up, except for 1 case of recurrence, the others had a favorable prognosis. Conclusions Renal abscess should be suspected for children presenting with unexplained fever, vomiting, abdominal pain,
