As will be seen by the consultation of any hospital record, the deaths in these various operations have been, in adults, from one in three to one in every four cases—a very large percentage, and sufficient to deter any sufferer from undergoing an operation except for the relief of a condition which is in itself worse than death. Even when this alarming death-rate is explained to sufferers, they willingly undergo the operation, feeling that they would rather die than longer continue in their pain and anguish.

Our specialists, not satisfied with the results of these operative measures, in their studies of the disease endeavored to perfect some other means by which these foreign bodies could be removed from the bladder without such great danger and pain. The operation by crushing, and removal without cutting, appeared to them to present the most practicable advantages, and they therefore devote their entire time to the improvement of this method for the removal of stone.

The method of crushing was first invented by a French surgeon many years ago; but, owing to his crude instruments, and the difficulty that was experienced in expelling the pieces of stone, the operation was seldom employed by surgeons. The improvements in these methods at the hands of Bigelow and Sir Henry Thompson, with those that have been made by our specialists, have resulted in our being able to present to sufferers with this disease, a means of cure which is, we are assured, the most successful known to modern medical science.

There have been so far in the history of the treatment of this malady by the new method of cure, one hundred and twenty-odd cases operated upon at the hands of prominent surgeons, all of which were with less perfect methods than that of our specialists, and there were but four deaths in this large number. By the advantages which are the result of further improvements by our specialists, we can assure you that this mortality is even less in our hands; in fact, approaches, as near as possible, to a perfect method of cure.

We think that in a moderately healthy subject, one in which the kidneys are not badly diseased as the result of irritation from the calculus, the operation is almost absolutely safe. The method consists in the crushing of the stone, and its removal from the bladder by means of small silver catheters attached to an apparatus which gently and perfectly removes, by suction, all the pieces which are thrown to the bottom of the bladder. This operation has now been performed in our institution in a very large number of cases with uniform success, and the cures have been effected in from six to eight weeks without a single unpleasant symptom arising during their progress. By this method it is not necessary to remove the entire calculus at one operation, if it is a large one. By the old cutting operation this was required, as the bleeding was great, and what was to be done had to be done immediately, or the patient would die from the hemorrhage. With the new method a part of the large calculus, or when several exist, one or two of them, may be removed at a time, after which the patient can rest and gain strength for the second; or, if necessary, for the third operation.

The largest stone removed by us in this way was one weighing between seven and eight hundred grains, for which three operations were required. It is necessarily performed under a mild anæsthetic, which prevents suffering and secures the perfect relaxation of the patient. In the case in which this large amount of stone was removed we feel certain that a cure could not possibly have resulted from a cutting operation, as the heart was seriously affected, and the physical condition of the patient so low, as the result of years of suffering, that death would have occurred while undergoing the operation. By carefully pursuing the new method, and not prolonging the sittings more than a few minutes each time, the entire stone was evacuated. The health of the patient constantly improved during the interval of three operations, which covered a space of seven weeks. This stone was as large as a hen's egg.

Small calculi or gravel are readily removed in a few moments' time by the new method. In no case is there any bleeding. Instead of a large, gaping wound being left after the operation, from which secondary hemorrhage may take place, or poisoning result from the irritation of decomposing urine, the parts are left in a healthy state with the surface unbroken. The stone, a constant source of irritation, is removed, and the health is speedily restored.

When it is impossible for the patient to visit us, a careful examination of the urine is made, and if gravel have been passed, these are carefully examined also. An idea of the composition of the stone is arrived at by this means, and treatment is directed to dissolve it. Success has commonly followed this method of treatment, when the stone has not been very large. With the gradual reduction of the size of the stone the irritation subsides, and the general health of the patient improves. (See Testimonials.)
