A Case of Matrix Stone / 대한비뇨기과학회지

ABSTRACT

Matrix stones are a rare form of urinary stones and composed primarily of matrix material, approximately 65% by weight. The characteristic X-ray feature is a radiolucent filling defect within the urinary system. The matrix stones are yellowish-white to light tan in color and have a consistency which ranges from that of gelatin to that of putty. We recently experienced a case of left renal matrix stone in 37-year-old woman who had another radiolucent stones in right ureter. So we report the case with a brief review of the literatures.
