The urinary endothelin level in patients with chronic liver disease was determined in order to explore its possible involvement in renal function. The plasma endothelin level was significantly higher in patients with liver cirrhosis (LC) than in those with chronic hepatitis (CH) or in control patients (C). Similarly, urinary endothelin excretion in LC was significantly increased, compared with CH and C. Urinary endothelin demonstrated a significant positive correlation with creatinine clearance. The ratio of endothelin clearance/creatinine clearance did not differ statistically among the three groups. Urinary sodium excretion in LC was positively correlated with plasma endothelin, but not with urinary endothelin. Urinary endothelin excretion demonstrated a significant negative correlation with urinary kallikrein in LC. The present data suggest that increased urinary endothelin excretion in cirrhotic patients primarily depends upon elevated plasma levels of endothelin, but not renal production. Also, a possible link between endothelin and the kallikrein‐kinin system in liver cirrhosis is indicated.
