Colonic Changes Secondary to Left Perinephritis: New Observations

Abstract

The distal transverse colon and, more constantly, the proximal descending colon are closely related to the left kidney. Advanced perirenal infection may break through fascial boundaries to involve the large intestine, particularly the segment distal to the splenic flexure. Changes range from inflammatory and spastic narrowing to gross extravasation. Though the clinical presentation is often nonspecific and misleading, recognition on an initial barium enema study leads to uncovering of the primary renal infection.
