This monograph on lower urinary tract obstruction in childhood represents an exhaustive study by Young of the anatomic, pathologic, physiologic, and embryologic aspects of the bladder and urethra in children. His hypotheses and conclusions are based upon a complete research of the available literature on the subject. He also utilizes his own painstaking observations, both gross and histologic, of normal embryos, fetuses, newborns, necropsy specimens of children dying with obstructive uropathy, as well as biopsy specimens obtained from surgical cases with congenital obstructive lesions.

The author has carefully, and in a very coherent fashion, related the physiology of the bladder urethral mechanism to
