EXSTROPHY OF THE BLADDER.

It is by some believedto be the result of the bursting of the allantois, caused by an unusualamount of secretion before the lower aperture for its escape had Fig. 14.—Exstrophy of the bladder and epispadias in a child five months old. Pathological Anatomy.—The anterior part of the abdominal wall isabsent, and there are often other congenital malformations, amongwhich is an absence of union at the symphysis pubis. The fissure mayextend to the urethra with epispadias, fissured scrotum, and unde-cended testes in the male, and open urethra and fissure of the labia andclitoris in the female. Symptoms.—The mucous membrane protrudes through a fissure inthe abdominal wall; it is of normal color, is folded into ridges, andis continuous with the skin of the abdomen. Any increase of intra-abdominal pressure causes a still further protrusion of the mass.
