vagina during first
coitus. Foucard reports a case of retention of urine in a young girl of
nineteen, due to accumulation of the menstrual fluid behind an
imperforate hymen.

The accumulation of urine in cases of ischuria is sometimes quite
excessive. De Vilde speaks of 16 pints being drawn off. Mazoni cites a
case in which 15 pounds of urine were retained; and Wilson mentions 16
pounds of urine being drawn off. Frank reports instances in which both
12 and 30 pounds of urine were evacuated. There is a record at the
beginning of this century in which it is stated that 31 pounds of urine
were evacuated in a case of ischuria.

Following some toxic or thermic disturbance, or in diseased kidneys,
suppression of urine is quite frequently noticed. The older writers
report some remarkable instances: Haller mentions a case lasting
twenty-two weeks; Domonceau, six months; and Marcellus Donatus, six
months.

Whitelaw describes a boy of eight who, after an attack of scarlet
fever, did not pass a single drop of urine from December 7th to
December 20th when two ounces issued, after vesication over the
kidneys. On January 2d two ounces more were evacuated, and no more was
passed until the bowel acted regularly. On January 5th a whole pint of
urine passed; after that the kidneys acted normally and the boy
recovered. It would be no exaggeration to state that this case lasted
from December 5th to January 5th, for the evacuations during this
period were so slight as to be hardly worthy of mention.

Lemery reports observation of a monk who during eight years vomited
periodically instead of urinating in a natural way. Five hours before
vomiting he experienced a strong pain in the kidneys. The vomitus was
of dark-red color, and had the odor of urine. He ate little, but drank
wine copiously, and stated that the vomiting was salutary to him, as he
suffered more when he missed it.

Bryce records a case of anuria of seventeen days' standing. Butler
speaks of an individual with a single kidney who suffered suppression
of urine for thirteen days, caused by occlusion of the ureter by an
inspissated thrombus. Dubuc observed a case of anuria which continued
for seventeen days before the fatal issue. Fontaine reports a case of
suppression of urine for twenty-five days. Nunneley showed the kidneys
of a woman who did not secrete any urine for a period of twelve days,
and during this time she had not exhibited any of the usual symptoms of
uremi
