Kidney Stones/Renal Stones

Kidney stones or renal stones are gravel-like collections of chemicals that may appear in any area of the urinary system, from the kidney to the bladder. They may be small or large, single or multiple.

The Times whereat you often in a day have the Urinary Excretion performed with Ease, are times which invite you very frequently to lift up your Hearts unto God with such an Acknowledgment as This; O,My most merciful God, I bless thee, that the grinding Torments of the Stone, are not now grinding of me. - Cotton Mather, 1724
