[Abscess of the kidney. Apropos of 21 cases]

Renal abscess is rather an uncommon lesion caused predominantly by an urogenic infection. The authors report 21 cases in a period of 10 years. They describe and evaluate the actual investigation possibilities which are accurate enough to lead to the right diagnosis of renal abscess in a good rate. The evolution of the therapeutic modes is studied, with a special reference to the percutaneous drainage which is to substitute the classical surgery of this abscess. For the authors, treated in the right time and in the right way, renal abscess is nowadays a benign lesion, preserving a good prognosis for the kidney and the patient.
