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.
