Nephrolithotomy is an operation for the removal of stone from the kidney. The operation may be a very difficult one, owing to the adhesions and thickening of all the perinephric tissues, or to the small size or remote location of the stone.
There was 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 the left kidney, dividing the ureter near the pelvis, and finally lodged in the psoas muscle.
It occasionally happens that the ureter is wounded in the removal of uterine, ovarian, or other abdominal tumors. In such event, if it is impossible to transplant to the bladder, the divided or torn end should be brought to the surface of the loin or vagina, and sutured there. In cases of malignant growth, the ureter has been purposely divided and transplanted into the bladder. Penrose, assisted by Baldy, has performed this operation after excision of an inch of the left ureter for carcinomatous involvement. The distal end of the ureter was ligated, and the proximal end implanted in the bladder according to Van Hook's method, which consists in tying the lowered end of the ureter, then making a slit into it, and invaginating the upper end into the lower through this slit. A perfect cure followed. Similar cases have been reported by Kelly, Krug, and Bache Emmet. Reed reports a most interesting series in which he has successfully transplanted ureters into the rectum.
Ureterovaginal fistulae following total extirpation of the uterus, opening of pelvic abscesses, or ulcerations from foreign bodies, are repaired by an operation termed by Bazy of Paris ureterocystoneostomy, and suggested by him as a substitute for nephrectomy in those cases in which the renal organs are unaffected. In the repair of such a case after a vaginal hysterectomy Mayo reports a successful reimplantation of the ureter into the bladder.
Stricture of the ureter is also a very rare occurrence except as a result of compression of abdominal or pelvic new growths. Watson has, however, reported two cases of stricture, in both of which a ureter was nearly or quite obliterated by a dense mass of connective tissue. In one case there was a history of the passage of a renal calculus years previously. In both instances the condition was associated with pyonephrosis. Watson has collected the reports of four other cases from medical literature.
A remarkable procedure recently developed by gynecologists, particularly by Kelly of Baltimore, is catheterization and sounding of the ureters. McClellan records a case of penetration of the ureter by the careless use of a catheter.
Injuries of the Bladder.—Rupture of the bladder may result from violence without any external wound (such as a fall or kick) applied to the abdomen. Jones reports a fatal case of rupture of the bladder by a horse falling on its rider. In this case there was but little extravasation of urine, as the vesical aperture was closed by omentum and bowel. Assmuth reports two cases of rupture of the bladder from muscular action. Morris cites the history of a case in which the bladder was twice ruptured: the first time by an injury, and the second time by the giving way of the cicatrix. The patient was a man of thirty-six who received a blow in the abdomen during a fight in a public house on June 6, 1879. At the hospital his condition was diagnosed and treated expectantly, but he recovered perfectly and left the hospital July 10, 1879. He was readmitted on August 4, 1886, over seven years later, with symptoms of rupture of the bladder, and died on the 6th. The postmortem showed a cicatrix of the bladder which had given way and caused the patient's death.
Rupture of the bladder is only likely to happen when the organ is distended, as when empty it sinks behind the pubic arch and is thus protected from external injury. The rupture usually occurs on the posterior wall, involving the peritoneal coat and allowing extravasation of urine into the peritoneal cavity, a condition that is almost inevitably fatal unless an operation is performed. Bartels collected the data of 98 such cases, only four recovering. When the rent is confined to the anterior wall of the bladder the urine escapes into the pelvic tissues, and the prognosis is much more favorable. Bartels collected 54 such cases, 12 terminating favorably. When celiotomy is performed for ruptured bladder, in a manner suggested by the elder Gross, the mortality is much less. Ashhurst collected the reports of 28 cases thus treated, ten of which recovered—a mortality of 64.2 per cent. Ashhurst remarks that he has seen an extraperitoneal rupture of the anterior wall of the bladder caused by improper use of instruments, in the case of retention of urine due to the presence of a tight urethral stricture.
