Urinary prostaglandins in kidney disease.

Substances having the chromatographic behaviour and the bioassay properties of prostaglandins (PGE and PGF) were detected in the urine of 30 patients with kidney disease and 15 healthy subjects. The mean urinary PGE and PGF values in 15 patients with chronic glomerular disease or nephrosclerosis were significantly lower than those of 15 patients with chronic pyelonephritis and other forms of chronic interstitial nephritis, polycystic kidney disease, obstructive nephropathy or diuretic phase of acute renal failure, and of the mean PGE and PGF values found in the healthy subjects. It was suggested that in contrast to disease affecting primarily the renal medulla, chronic glomerular disease and nephrosclerosis are accompanied by a decrease of renal prostaglandin synthesis and/or release.
