Psoas abscess in obstetrics.

Psoas abscess is rarely encountered in obstetric practice. This condition may be primary or secondary resulting from extension of an infectious process near the psoas muscle. We report a series of three patients with psoas abscess that were encountered in our obstetric practice. Two of these patients had a primary and one a secondary abscess. Two patients underwent laparotomy and drainage of abscess while one received medical treatment. All patients recovered uneventfully.
