Clinical study on correlation with the 60-min plasma phenolsulfonphthalein concentration and other renal function tests.
An analysis of the reliability of the 60-min plasma phenosulfonphthalein concentration (PSP60) as a renal function test has been made in 40 patients with or without urinary dead space. PSP60 correlates with 15-min urinary PSP excretion and 24-hour endogenous creatinine clearance in patients without urinary dead space. 15-min urinary PSP excretion showed unreliability as a renal function test in patients with urinary dead space. However, we confirmed that PSP60 and 24-hour endogenous creatinine clearance were reliable indicators of renal function in these patients.
