Purpose: This study was performed to assess the recent trend of renal or perirenal abscess.
Materials and Methods : We have analyzed retrospectively 18 in-patients with renal or perirenal abscess at our hospital from June 2002 to May 2009.
Results: Mean age was 49.1±18.4years. Thirteen cases were renal and 5 cases were perirenal abscess. The most common predisposing factor was diabetes mellitus (22.2%). Fever with flank pain (66.7%) was the most common symptom. The duration of symptom was longer in patients with perirenal abscess (9.6 days) than renal abscess (5.9 days). On the urine culture, 4 cases of E. coli (22.2%) were detected. On the blood culture, 3 cases were positive; E. coli was in 2 cases and S. epidermidis in 1 case. Among 10 cases of abscess culture, E. coli was in 8 cases and S. epidermidis was in 1 case. The remaining 1 case was sterile. Most of patients were diagnosed by CT scan with ultrasonography (94.4%). Antibiotics only treatment was done in 9 patients (50%) with small renal abscess (<30mm). Four (2.2%) of percutaneous aspiration was done (renal 2, perirenal 2). Three cases (16.7%) of surgical drainage was done (renal 1, perirenal 2). One case of nephrectomy in non-functioning kidney and 1 case of double-J stenting with ESWL was done.
Conclusions: We suggest that the early detection by CT scan with ultrasonography and the proper selection of management is very important in successful outcome of renal or perirenal abscess.
