Bussiere describes a
triple bladder, and Scibelli of Naples mentions an instance in a
subject who died at fifty-seven with symptoms of retention of
urine. In the illustration, B represents the normal bladder, A
and C the supplementary bladders, with D and E their respective
points of entrance into B. As will be noticed, the ureters
terminate in the supplementary bladders. Fantoni and Malgetti
cite instances of quintuple bladders.
The Ephemerides speaks of a case of coalition of the bladder with
the os pubis and another case of coalition with the omentum.
Prochaska mentions vesical fusion with the uterus, and we have
already described union with the rectum and intestine.
Exstrophy of the bladder is not rare, and is often associated
with hypospadias, epispadias, and other malformations of the
genitourinary tract. It consists of a deficiency of the abdominal
wall in the hypogastric region, in which is seen the denuded
bladder. It is remedied by many different and ingenious plastic
operations.
In an occasional instance in which there is occlusion at the
umbilicus and again at the neck of the bladder this organ becomes
so distended as to produce a most curious deformity in the fetus.
