A matrix calculus obstructed the ureter of a solitary kidney during pregnancy. Anuria and azotemia were reversed by extracting the calculus. The matrix was an amorphous mass of glycoprotein and mucopolysaccharide; there were only microscopic nests of calcium. Only electron micrographs demonstrated a tendency of the crystals and matrix to display lamellae. This unusual architecture suggests matrix calculi can grow without organized lamellae.
