Compounds that increase urine volume by increasing the amount of osmotically active solute in the urine. Osmotic diuretics also increase the osmolarity of plasma.

In the thyroid gland, oxyphil cells are known as Hurthle cells and Askanazy cells.

Deliberate introduction of air into the peritoneal cavity.
