[Percutaneous drainage in the treatment of kidney abscess. Apropos of 2 cases].

Percutaneous drainage has rapidly become the initial procedure of choice in the treatment of most intra-abdominal and retro-peritoneal abscess. The retro-peritoneal location of the urinary tract facilitates a percutaneous approach and has been found to be highly effective. We report 2 cases of successful non operative managements of renal abscess by percutaneous aspirations and systemic antibiotic therapy.
