[A silica urinary calculus secondary to the absorption of gelopectose in a child].

The authors report a case of silica-containing urinary stones in a child. This drug-induced urinary stone was secondary to absorption of Gelopectose and its composition was confirmed by infrared spectrophotometry. Other cases have been diagnosed but have not yet been published. Patients with such urinary stones should be investigated for possible hypercalciuria or a disorder of H+ metabolism in the context of distal tubular acidosis, which may be incomplete and/or transient.
