Abstract

"Purpose: The objective was to analyze the renal and perinephric abscesses with treatment as the center. Patients and methods: The medical records of 47 patients with renal and prinephric abscesses treated at our hospital from January 1990 to December 2007 were reviewed. The data collected included underlying conditions, size and multiplicity of abscess, cultured organisms, associated disease and treatment method. Results: The mean age of the patients was 47.7 years old (4~84), and men and women were 12 and 35 cases, respectively. In 24 cases the abscess were happened in right kidney, and bilateral cases were 4 cases. Multiple abscess were 11 cases, and the size of abscess was variable from 1cm to 6cm. Below 4cm size of abscess were 25 cases, and beyond 4cm size of abscess were 22 cases. Diabetes mellitus (31.9%), hypertension (17.0%) and urolithiasis (12.8%) were the most common underlying conditions and 11 cases were multiple. The abscess size of twenty-five cases were less than 4cm. Pyuria were found in 29 (61%) and causative organisms were found in 17 cases. The most common organisms are E. coli. Interventional treatments were performed in 23 cases: surgical drainage (1 case), percutaneous drainage (13 cases), nephrectomy (9 cases). Among the percutaneous drainage, nephrectomy was done in 2 cases. Open surgery was performed in cases that associated urologic disease existed, abscesses were multiple and abscess size was more than 4cm. The interventional treatment was decreased after 2000 year. Conclusions: Renal and perinephric abscesses are successfully managed by medical treatment. But for more good results, we considered underlying conditions, size and multiplicity of abscess."
