Materials and Methods: Urine obtained from contralateral kidneys in pigs with UUO and from the right kidney in sham-operated pigs was examined for prostaglandin E2 (PGE2) and thromboxane B2 (TxB2) by radioimmunoassay. Results: Excretion rate of PGE2 increased from 307 plus/minus 69 pg. per minute to 542 plus/minus 149 pg. per minute (p less than 0.05) during UUO. Indomethacin blocked the synthesis of both PGE2 and TxB2. Administration of an inhibitor of the angiotensin I converting enzyme resulted in a significant (p = 0.02) reduction of PGE2 excretion as well as a decrease in TxB2 excretion which was significantly lower 15 hours after UUO. Blockade of angiotensin II synthesis in the sham-operated pigs did not affect prostanoid excretion from their kidneys. Conclusion: This study demonstrates that the presence of angiotensin is important for a full expression of these prostanoids in the contralateral kidney during UUO References 1 : Effects of urinary obstruction on glomerular filtration rate and renal blood flow.
