Costovertebral angle tenderness
From Wikipedia, the free encyclopedia
(Redirected from Murphy's punch sign)
Kidney punch or CVA Tenderness is elicited when gently tapping the area of the back overlying the kidney producing pain in people with an infection around the kidney (perinephric abscess) or pyelonephritis or renal stone. Since the kidney lies directly below this area, known as the costovertebral angle, tapping disturbs the inflamed tissue causing pain.
This medical test was first described by the American surgeon John Benjamin Murphy.[1][2][3]
