title: Secondary psoas abscess twenty-seven years after nephrectomy.
abstract: Abscesses of the psoas muscle are due to a hematogenous dissemination, to the spread of infection from adjacent intestinal structures, to osteomyelitis of the spine or to tuberculous infection of a disc space. In contrast, psoas abscesses related to the urological tract have only been described on exception. The present report focuses on a right psoas abscess which developed 27 years after a nephrectomy. The infectious process resulted from the spread of an acute vesical infection through the residual ureter. Analysis of 4 other cases reported in the literature allows us to delineate the clinical features of psoas abscesses of urological origin.
