To the Editor:—  I agree wholeheartedly with the conclusions of Hamby and Kirsh (JAMA189:582 [Aug 17] 1964) that abdominal compression improves the diagnostic quality of excretory urograms. However, their statement that abdominal pressure had not been previously successful is not true. In 1955 I reported on this technique (Radiology65:265, 1955) and have since demonstrated complete filling of the renal pelvis in a very high percentage of cases. The need for retrograde pyelograms has correspondingly decreased. Scandinavian physicians deserve credit for demonstrating this important principle. Olle Olsson, A. Lindbom, and J. Frimann-Dahl published extensively on this subject, with brilliant illustrations. Although the efficacy of compression has been demonstrated for almost 20 years, the procedure, for some unknown reason, has only recently come into general use in the United States.The authors' method of using small compression blocks is excellent, although other methods have proved equally efficacious.
