. The functional significance of renographic delay in excretion observed in connection with chiefly unilateral “physiologic” hydronephrosis of pregnancy was analyzed in 10 cases. The delay was found to be entirely or predominantly due to the reservoir effect of the dilated urinary tract. A moderate reduction of urinary flow on the affected side was suggested to contribute to the impairment in only 3 of the 10 cases. Interpretation of the degree of urinary obstruction as judged by renography should be cautious. This applies especially to the assessment of complete obstruction, which should be diagnosed only after considering the reservoir effect of the dilated tract.
