5.8\ Congenital Small Renal Artery

Fig. 9.24  Congenital small renal artery

5.8.1\ Scanning Method

The method is the same as that used to examine the renal artery.

5.8.2\ Section Structure

Longitudinal view of the congenital small renal artery, coronal or transverse view of the kidney.

5.8.3\ Measurement Method and Normal Value

The kidney is smaller than normal, with a clear structure and normal cortex. The renal artery is

thin with normal or low blood flow velocity; the spectrum shape is usually normal.

5.8.4\ Clinical Application Value

A small kidney can be caused by a chronic renal stenosis or chronic nephropathy; it should be differentiated from a congenital small renal artery; the latter is associated with a normal kidney structure and a normal renal artery spectrum.
