“…Urinalysis may demonstrate pyuria and leukocyturia in the setting of abscess that complicates acute pyelonephritis 3 5 8 10. In contrast, urine studies may be normal if renal or perinephric abscess develops as a result of haematogenous spread and does not communicate with the collecting system, or if they are performed after the beginning of antibiotics, as in the second case 6 7 10…”

Renal abscesses in childhood: report of two uncommon cases

et al. 2014

Renal abscesses are rare conditions in children, but they must be remembered in differential diagnosis of fever and abdominal pain. The authors report two paediatric cases with unusual presentation. Case 1: a 15-year-old girl was admitted following a period of fever, vomiting and left hypochondrium pain which became more localised to the left lower ribs. Blood tests suggested bacterial infection, but urinalysis and culture were negative. Renal CT scan presented features of bilateral pyelonephritis and left renal abscesses, while ultrasound remained normal until the ninth day of disease. Case 2: a 2-year-old girl, with diagnosis of β-thalassemia minor, had intermittent diffuse abdominal pain with 2 weeks of evolution. Renal ultrasonography and CT scan showed a heterogeneous mass compatible with Willms tumour. Intraoperative diagnosis was compatible with renal abscess with isolation ofProteus mirabilisin the fluid. Both responded well to long-term antibiotics and to surgical drainage (in the second case).

Bilateral renal abscess in a previously healthy 11-year-old girl

Renal abscesses are infrequently encountered in children. We describe a girl diagnosed with bilateral renal abscess. Although ultrasonography and computerised tomography are used to establish the diagnosis, in our case magnetic resonance imaging proved to be a useful additional diagnostic method. Using percutaneous aspiration, we were able to establish the correct diagnosis and identify the causative micro-organism. The patient was successfully treated with a combined intravenous and oral course of antibiotics. In conclusion, renal abscesses can occur in children without a history of reflux or urinary tract infection; this should be kept in mind when evaluating a child with fever. In addition, full recovery can be achieved solely with antibiotics.

“…Escherichia coli is the most etiological bacteria, which is found in the urine in less than half of the cases and even less frequently in the blood (1,8). Diagnosis is typically based on high suspicion of the diagnosis and confirmed by renal ultrasound, and computed tomography of (CT) abdomen (3,8,9). Treatment in most cases consists of intravenous antibiotics; in a small percentage of cases, a CT guided percutaneous drainage is indicated, especially for larger abscesses.…”

Infected renal hematoma in a healthy adolescent with no renal structural anomaly

2018

View full text Add to dashboard Cite

Renal abscesses are uncommon in otherwise healthy children and adolescents who have no underlying renal structural anomalies. A previously healthy, immunocompetent, 14-year-old male without a history of abdominal trauma or urinary tract infection (UTI) was found to have a renal hematoma that became infected and developed into a renal abscess. He presented with a 2-day history of nausea, vomiting, fever and 1-day history of abdominal pain that radiated to the right flank. Clinical examination, blood work, and initial imaging indicated likely infection; however, findings were normal on urinalysis and urine culture had no growth. Complete blood count (CBC) showed a leukocytosis with a left shift. Renal ultrasound showed a 4-cm mass-like area of liquefaction in the upper pole of the right kidney, confirmed by abdominal computed tomography (CT) scan with and without contrast. Intravenous ceftriaxone was started and the patient continued to improve. He was discharged on hospital day 6 after remaining afebrile for over 20 hours and inflammatory markers continued to decrease. Intravenous ceftriaxone was continued, and oral clindamycin was added. Both antibiotics were discontinued on day 24 since onset of illness.
