Nephron number in patients with primary hypertension.

Background: A diminished number of nephrons has been proposed as one of the factors contributing to the development of primary hypertension.

Methods: To test this hypothesis, we used a three-dimensional stereologic method to compare the number and volume of glomeruli in 10 middle-aged white patients (age range, 35 to 59 years) with a history of primary hypertension or left ventricular hypertrophy (or both) and renal arteriolar lesions with the number and volume in 10 normotensive subjects matched for sex, age, height, and weight. All 20 subjects had died in accidents.
