Silica urolithiasis without magnesium trisilicate intake

Urol Int. 1998 Oct;61(1):39-42. doi: 10.1159/000030282.

Abstract

Two cases of silica stones, without previous oral intake of magnesium trisilicate, are reported. A 64-year-old Japanese woman had bilateral renal stones. Infrared spectrophotoscopy revealed that one of the fragments consisted of silicate and the others consisted of calcium oxalate. A 75-year-old woman had right renal stones. The composition of 1 stone was a mixture of silicate and unspecified matrices. Silicate urolithiasis may not necessarily be related to oral intake of silicate-containing antacids.
