Renal Interstitial Pressure in Normal and in Anuric Man: Based on Wedged Renal Vein Pressure.

A method is described for determination of wedged renal vein pressure (WRVP) in man. 2. In 9 normal subjects WRVP averaged 18 mm Hg. It was not possible to demonstrate a raised WRVP in 4 patients with acute anuria following shock, the average WRVP being 20 mm Hg. 3. It is argued that in agreement with experiences from lungs and liver, the interstitial pressure in kidneys equals the WRVP. The results suggest that in patients with acute anuria following shock the anuria cannot be explained by an increased interstitial renal pressure.
