a recent exhibition in London, in which were shown the
results of a number of recent operations on the kidney. There was
one-half of a kidney that had been removed on account of a
rapidly-growing sarcoma from a young man of nineteen, who had known of
the tumor for six months; there was a good recovery, and the man was
quite well in eighteen months afterward. Another specimen was a right
kidney removed at St. Bartholomew's Hospital. It was much dilated, and
only a small amount of the kidney-substance remained. A calculus
blocked the ureter at its commencement. The patient was a woman of
thirty-one, and made a good recovery. From the Middlesex Hospital was a
kidney containing a uric acid calculus which was successfully removed
from a man of thirty-five. From the Cancer Hospital at Brompton there
were two kidneys which had been removed from a man and a woman
respectively, both of whom made a good recovery. From the King's
College Hospital there was a kidney with its pelvis enlarged and
occupied by a large calculus, and containing little secreting
substance, which was removed from a man of forty-nine, who recovered.
These are only a few of the examples of this most interesting
collection. Large calculi of the kidney are mentioned in Chapter XV.

Rupture of the ureter is a very rare injury. Poland has collected the
histories of four cases, one of which ended in recovery after the
evacuation by puncture, at intervals, of about two gallons of fluid
resembling urine. The other cases terminated in death during the first,
fourth, and tenth weeks respectively. Peritonitis was apparently not
present in any of the cases, the urinary extravasation having occurred
into the cellular tissue behind the peritoneum.

There are a few recorded cases of uncomplicated wounds of the ureters.
The only well authenticated case in which the ureter alone was divided
is the historic injury of the Archbishop of Paris, who was wounded
during the Revolution of 1848, by a ball entering the upper part of the
lumbar region close to the spine. Unsuccessful attempts were made to
extract the ball, and as there was no urine in the bladder, but a
quantity escaping from the wound, a diagnosis of divided ureter was
made. The Archbishop died in eighteen hours, and the autopsy showed
that the ball had fractured the transverse process of the 3d lumbar
vertebra, and divided the cauda equina just below its origin; it had
then changed direction and passed up toward
