Summary— Fifty‐seven patients have provided 64 dilated pelvicaliceal units for study by diuresis renography and the Whitaker test. Of 45 kidneys showing a type I or type Illa renographic response (unobstructed), 32 were, according to Whitaker's criteria, obstructed, 8 fell into an equivocal zone and only 5 were unobstructed. Thirty‐five of these kidneys—33 of which were associated with moderate or severe loin pain—were operated on for presumed obstruction with generally excellent symptomatic and renographic result. Thus the detection of a type I or type Illa response in a dilated, painful system cannot be taken to exclude obstruction. Better correlation was obtained between renography and the Whitaker test in patients exhibiting a type 1Mb or type Il renographic response. Diuresis renography is a sensitive indicator of urodynamic disturbance in the upper urinary tract and an ideal means of evaluating post‐operative progress. The Whitaker test provides a reliable means of selecting patients who will benefit from pyeloplasty.
