CLINICAL STUDY ON RENAL FUNCTION AFTER SURGICAL OPERATION
I RENAL FUNCTION AFTER SURGICAL OPERATION BY METHOD OF CLEASANCE TEST

The author has investigated, in about 100 clinical materials the inflence of surgical operation on renal function and the correlation between blood pressure, circulating blood volume and urine volume etc, and more discussed the mechanismus of the postoperative oliguria.
In Part I. it was investigated the direct inflence on renal function for several hours after operation, and was assumed the hypersecretion of adrenalin which was an important cause of the recuced renal function.
(1) Both Glomerular Filtration Rate (GFR) and Renal Blood Flow (RBF) reduced in 53.1%, and in such instances the intraglomerular pressurs raised markedly ; Vasa efferentes constricted more distinctly than vasa affersntes.
(2) Oxford shunting (Trueta) was observed in 35.1% which was assumed in such instances that the stress was severe and the bleeding much also.
(3) Blood pressure and crculating blood volume was correlated closely with GFR and RBF as a rule.
(7) GFR and RBF were not always parallel to urine volume. It was assumed that the cause of postoperative oliguria was the reduced renal function and the hyperserretion of antidiuretic hormone of the hypophysis. (author's abstract)
