An experimental model in conscious dogs was developed to investigate the role of prostaglandins (PG) in the obstructed kidney. Renal veins were separately catheterized. Urine flow was shunted to the skin by surgically implanted polyurethane loop ureterostomy so as to allow atraumatic manipulation with maintained continuous flow to the bladder between experiments. One week or more after surgery, renal function parameters as well as renal vein and urinary PGE2 and PGF2 alpha, and renal vein renin were studied during and after unilateral (UUO) and bilateral (BUO) ureteral obstruction. The release of ureteral obstruction produced a constant and marked elevation in urinary PGE2 and PGF2 alpha, two times higher after BUO than after UUO. A close correlation exists between PGE2 and sodium excretion in UUO and BUO. Increasing polyuria was observed only after chronic BUO. In BUO, renal vein renin concentration was augmented after 2 hours but was suppressed after 24 hours of BUO. Renal vein PG concentration was also elevated after chronic UUO and BUO but was in the normal range immediately prior to release of obstruction. The data obtained with the current experimental dog model indicate that the release of ureteral obstruction induces a striking increase in renal PGE2 and PGF2 alpha production which may mediate at least partly the phenomenon of postobstructive diuresis.
