Abstract

PURPOSE: We critically evaluated the most appropriate management of renal and perirenal abscess and identified the set of patients who had benefited from conservative management.
MATERIALS AND METHODS
Between May 1995 and June 1999, fifteen patients with renal (10 cases) and perirenal abscess (5 cases) were treated in our hospital. Among the fifteen patients, six patients were managed by antibiotics alone, the other nine patients were managed by percutaneous aspiration and antibiotics. Percutaneous abscess aspiration and drainage was done under ultrasound guidance and local anesthesia.
RESULTS
On the urine culture, 4 cases had positive urine culture (27%); E. coli was in 3 cases, Klebsiella in 1 case respectively. On the blood culture, E. coli was in 2 cases. On the abscess culture (9 cases were performed), the organisms were identified in 8 cases (89%); E. coli was in 6 cases, S. aureus was in 1 case, S. epidermidis in 1 case respectively.
CONCLUSIONS
We suggest that proper antibiotic therapy alone or combined with ultrasound guided percutaneous drainage of renal and perirenal abscesses is a choice of reasonable, safe and effective management in selected patients.
