Background : The clinical aspects of renal or perirenal abscess has changed over the decades. In Korea, there were no recent reports about clinical aspects of renal or perirenal abscesses.
Methods : We retrospectively reviewed charts of 34 patients diagnosed as renal or perirenal abscesses about age, sex, clinical manifestations, laboratory findings, culture studies, underlying conditions, radiologic findings, treatment modalities, duration of treatmer and treatment outcomes.
Results : A total of 34 patients with renal or perirenal abscess was identified. The mean age of. overall patients was 52.912.9 years. Underlying conditions were diabetes mellitus(32.9010), liver disease(20.5%), steroid use(14.7%), malignancy(8.8%), neurogenic bladder(5.8%o), polvcvstic kidnev(5.8%) and renal stone(2.9%). Common clinical manifestations were fever(82.3%) and flank pain(67.6%). ´ Gram negative strains such as Escherichia coli, Klebsiella pneumoniae were common causative organisms. Mean size of abscess was 5.27 3.05cm(0.5-13.Ocm). There were no significant differences in the hospital days or treatment duration between treatment modalities such as antibiotics, percutaneous drainage and surgery. There were no significant differences in the clinical characteristics between renal and peri renal renal abscess.
Conclusion : In our study, there were changes of clinical characteristics such as 4 W, causative organisms or treatment modalities similar with that in foreign countries. The prospective study should be processed about treatment outcomes of noninvasive treatment in renal or perirenal abscess.
