Is pregnancy a risk factor for kidney stones?

In the urine of pregnant women, a relatively high content of silicon was found, which increases the colloidal properties of urine and prevents the precipitation of the ingredients of urinary stones (urates, phosphates, oxalates). At the same time, it is known that during pregnancy such factors appear and increase in intensity that contribute to stone formation in the urinary tract - urinary stasis, urinary tract infection, shifts in electrolyte metabolism. A similar situation is observed in patients with silicosis, who also have a high content of silicon in the urine, but it does not reach such values ​​as in pregnant women. For the same reason, patients with silicosis rarely develop urolithiasis. With an increase in the number of pregnancies, the risk of urolithiasis does not increase.
