In order to reassure and educate pregnant clients about the functioning of their kidneys in eliminating waste products, maternity nurses should be aware that:

Increased urinary output makes pregnant women less susceptible to urinary infection.

Renal (kidney) function is more efficient when the woman assumes a supine position.

Increased bladder sensitivity and then compression of the bladder by the enlarging uterus results in the urge to urinate even if the bladder is almost empty.

Using diuretics during pregnancy can help keep kidney function regular.
