Part 69
Many patients have perished within the first day or two from bleeding, owing to the using of the knife too freely, and in an improper direction. By very slight application of the edge to the resisting fibres, and by gentle dilatation with the finger, the membranous portion of the urethra is reached. The knife is passed over the back of the forefinger in the wound, and lodged in the groove of the staff; it is then carried forwards through the prostate, with the edge directed downwards and outwards, cutting the gland obliquely. In this incision the knife is raised very little from the groove, the object being to divide the gland to the extent of no more than barely three-quarters of an inch. By so doing, the reflection of the pelvic fascia remains uninjured, and the boundary is left entire betwixt the external cellular tissue, and that loose and very fine texture immediately exterior to the bladder—betwixt it and the fascia lining the pelvis; thus the risk of urinary infiltration is done away with, at least much diminished. There is great danger in dividing the base of the prostate completely, and much more in cutting any part of the coats of the bladder. When the knife enters the groove of the staff, this latter instrument must be held very steady; if it be at all withdrawn, its point may escape through the wound, and mislead the knife.
There is no great risk of wounding the trunk of the pudic artery, unless by using either a broad instrument called the gorget, or a concealed knife. The former is now almost wholly abandoned. Besides endangering the pudic, it is apt to lacerate the neck of the bladder, pushing the prostate before it, and so tearing its cellular connexions. The latter, the lithotome caché, makes the internal wound larger than the external; the coats of the bladder are slit up to an unnecessary extent, being cut much more easily than the prostate, and the instrument not affording sufficient resistance to the gland.
Through the prostatic opening the finger is easily passed into the bladder, and the stone felt. The staff is then withdrawn. Sometimes it is a troublesome matter to reach the bladder with the finger, in consequence of the straining and struggling of the patient, causing the organ to ascend in the pelvis; the difficulty is overcome by patiently waiting till these exertions cease. By steady and gradual movements of the finger in the wound of the prostate, the opening is much dilated, so as to admit of the ready introduction of instruments for laying hold of and removing the stone. Indeed, the neck of the bladder is capable of dilatation without any incision. In a case of perineal abscess containing a portion of exfoliated bone, on account of which incision was made, it was found that the cavity communicated with the urethra; lest other foreign matter should remain, I introduced my finger into this aperture in the membranous portion, and found that by the most gentle movement I could not only easily reach the bladder, but dilate the opening in it to a very considerable extent.
By the finger in the bladder, the size and position of the stone is ascertained; and no extracting instrument should be employed till after the finger is in contact with the stone. When it is of moderate size, and after having been turned, if necessary, into the most favourable position for extraction, the forceps are introduced. This instrument should be tolerably long, so as to afford power in its use; and the extremities of its blades should be covered with coarse linen, for thus it is not so likely to slip or to chip the stone as those with raised and projecting teeth. For flat stones, the forceps should be flat-mouthed; for round, more open, hollowed, and bent at the points; or for the latter description of stone, forceps with a sliding joint may be used. The object is to lay hold of the concretion by as many points as possible—to bring a large surface in contact with the instrument. Those with the sliding joint are of no service when the stone is flat, as it either cannot be caught by them at all, or merely by their points, or near the joint; they are applicable only to round stones of considerable size, but they are very troublesome to manage. The instrument is introduced shut, along the finger, and on reaching the prostate is gently insinuated, whilst the finger is at the same time withdrawn. It is brought in contact with the stone, and carefully opened, the handles being raised. One blade is passed under the stone, the other remaining above, and then the instrument is closed, firmly but not forcibly. By the finger, again introduced, along the side of the forceps, it is ascertained whether or not the stone is held securely, and in the proper direction; if not all right, it may then be turned by using the point of the finger and slightly relaxing the grasp. Now the handles of the instrument are depressed, so as to avoid resistance from the bones in the front of the pelvis, and the extraction is commenced, in a steady and gradual manner; if difficulty is experienced, dilatation is effected, and the process facilitated, by moving the forceps gently backwards and forwards; no force or violence is required, either in pulling or dilating; all should proceed smoothly and with deliberation.
The forceps must be proportioned in length to the size of the stone; a large concretion requires long forceps, both that it may be grasped securely, and that sufficient power may be afforded for the extraction.
Some stones are of such a size as will not admit of passage through the section of one side of the gland. By using the blunt-pointed knife, directed by the finger, without any additional external incision, a wound is made on the right side of the prostate, in the same direction and to the same extent as that on the left. Thus a triangular flap is formed, the apex towards the membranous portion of the urethra, and through the opening thereby afforded any stone, which will pass through the bones of the pelvis, can be extracted without much difficulty. But no benefit can result from cutting both sides of the prostate, either by the double lithotome or in the manner just detailed, in all cases. It is time enough to incise the opposite side when, by introduction of the finger through the usual wound, it has been ascertained that the stone is too large to pass through it. Then it is safer to cut the other side, than to enlarge the original opening, either by the knife, or by laceration in cruel attempts to extract the stone through an insufficient opening.
When the stones are small, the scoop is the preferable instrument. By it the bladder may be soon cleared, even when the concretions are numerous. It is introduced along with the finger, is brought in contact with the foreign body, and passed beyond it or beneath it. Then the point of the finger is placed on the lower part of the stone, so as to steady and secure it, and the scoop and finger retaining this relation are gradually withdrawn along with the stone. More than one, perhaps, may be removed at each withdrawal of the instrument. The flat and slightly bent lever, usually forming the handle of the scoop, is useful should the forceps unfortunately slip during extraction, leaving the calculus impacted in the wound; by insinuating this instrument behind the stone, and employing it partly as a lever, partly as an extractor, removal is completed.
If the stone break, which should not often happen if the forceps be used properly, the fragments must be carefully brought away, the larger by the forceps, the others by the scoop. The sand and detritus which may remain are washed away by injecting tepid water into the bladder, afterwards promoting copious secretion of urine by diluents.
After almost every operation for stone, particularly when the concretions are numerous, or when they have broken into fragments, a searcher is useful to ascertain whether or not all have been removed. It is a slightly curved sound, with a bulbous point. Having been introduced by the wound, it is passed into every part of the bladder with great care, with the view of detecting small calculi, or fragments, which may have escaped the search of the finger, forceps, and scoop. Besides this precaution, the extracted fragments should be carefully examined, and the stones built up, that the surgeon may better judge if they be all there. The surface of the stone affords considerable information; if it be uniformly rough, the likelihood is that it is solitary; if one or more points are smooth, it is probable that these have been occasioned by the attrition of other calculi. If suspicion still exist of part remaining, examination may be made through the wound, during the suppurative stage, six or eight days after the operation, before it has closed much.
It has been proposed to break the stone when very large, to facilitate its extraction, and many instruments have been contrived for the purpose. I have had no experience of the proceeding, but consider the following description of instrument as the best adapted for the purpose—strong, massy forceps, of considerable length; the blades proportionally narrower, but much thicker, than those of the extracting forceps, and armed with several strong teeth, thick at their origin, tapering gradually, and terminating in a sharp ridge; the handles also thicker than they are broad, that they may not yield to the compressing force, and approximated by means of a combination of the lever with the screw. The foreign body is secured firmly between the blades closed on it; the handles are then fixed by a screw and nut, and compressing force is exerted by the lever acting both as a lever and a wedge. The screw, turned by the fingers, will suffice to crush many concretions; and none can withstand the full power of the instrument. But it is, perhaps, safer to open the bladder above the pubes, and extract the stone through a wound in that situation, when it is too large to pass betwixt the rami of the ischia.
When the stone or stones have been extracted, and the surgeon has satisfied himself that no more foreign matter remains in the bladder, the next step in the lateral operation is the insertion of a gum-elastic tube, from four to six inches in length, according to the depth of the perineum, in calibre a little larger than a full-sized catheter, provided with a noose attached to each of two rings at its neck, and at its farther extremity open at both point and sides. It is introduced along the forefinger in the wound, and its extremity lodged fairly within the bladder; a double tape is attached to each of the nooses at its orifice; one is passed up in front, and secured to the fore part of a broad band round the loins; the other is brought under the thighs, and fixed behind. The object of its introduction is to facilitate the escape of urine externally, and prevent infiltration of the cellular tissue by this fluid. The wound, when made according to the directions which have been given, is both conical and dependent—the external opening is free, the internal small, the intermediate space gradually contracting as it approaches the bladder, and the inferior part of the wound of the integument is lower than the corresponding portion of the prostatic section; thus the draining away of the urine is favoured, but it conduces very much to the patient’s safety to ensure still farther its free escape by the insertion of a tube—part passes through the tube, and drops from its orifice, part flows by its side according to the laws of capillary attraction. For some hours after the operation, it is necessary to clear out the instrument frequently by means of a feather, otherwise its extremity will soon become obstructed by coagula; in short, this must be persevered in till colourless flow from the orifice shows that the internal oozing of blood has ceased, and that nothing is passing but urine. When by salutary effusion from the vessels the surface of the wound becomes consolidated and imperviable to the urine, the tube is to be withdrawn, but not till then; in young persons it may be removed after twenty-four hours, but in those advanced in life and of relaxed habit it must be retained for forty-eight or more.
The tube is also of service should bleeding continue from branches of the superficial pudic, from small arterial twigs in the neighbourhood of the prostate, or from venous ramifications and the plexus which surrounds the neck of the bladder; for it admits of the application of efficient pressure to the bleeding point, without interfering with the escape of urine, and so increasing the danger of infiltration. Slips of lint are pushed along it to a sufficient depth, and are retained, if necessary, by compress and bandage, the orifice of the tube being left clear. But, as already stated, it is indeed very seldom that this proceeding will be required, if the operation has been conducted with proper caution.
After the tube has been secured by its tapes, or during this process, the patient is unbound; he is placed in bed with the thighs separated and bent, and must be kept very quiet. Diluents are administered copiously, to encourage the secretion of urine; he cannot wet too much. His nourishment must be very sparing, consisting chiefly of bland fluids; and all sources of inquietude and irritation must be carefully avoided. Depletion, whether general or local, will very seldom be required; danger is not to be apprehended from inflammation so much as from infiltration of the cellular tissue by urine. In the fatal cases, unconnected with hemorrhage or exhaustion, the peritoneum is not found vascular or coated with lymph, nor is there collection of morbid secretion from this membrane within the abdominal cavity, but the cellular tissue, along the track of the wound, is black, disorganised, easily lacerable, putrid; or, if the infiltration has not been to such an extent or in such a site as to kill speedily as if by poisoning, unhealthy suppurations are found, extensive, uncircumscribed, composed of sanies, urine, and dead cellular tissue, horribly mixed. Should fixed and increasing pain be complained of in the hypogastrium, the part is to be leeched and fomented; this is the only indication of inflammatory action which has occurred in any of my patients, and it has yielded to the simple treatment here mentioned; so far as I recollect, in only three cases out of more than a hundred, was the leeching necessary. Some patients require support very soon, almost from the first; others evince sufficiency of action throughout, and in them it is very necessary to pay strict attention to the state of the stomach and bowels, lest the action should exceed; some proceed favourably for a time, and then become torpid and stationary, their spirits and constitutional power flagging, in consequence of confinement and the discharge and irritation of the wound,—such also require judicious support, and perhaps slight stimulation.
Union of the wound by the first intention is not desirable; attempts to procure it are dangerous, as conducing to infiltration; the presence of the tube effectually prevents both. Discharge and granulation take place, and the cavity contracts gradually and uniformly. By the sixth or eighth day—sooner in young people, and later in those far advanced in life—the urine begins to flow in part by the natural passage, causing considerable pain in consequence of the urethra having been for a time unaccustomed to its stimulus; and as the opening in the prostate contracts, the escape of urine by the wound proportionally diminishes. When the natural course is completely restored, the wound closes more rapidly than before, granulations soon fill it up, and cicatrisation takes place. Sometimes, though very rarely, a small fistulous opening remains for some time, through which a few drops of urine may occasionally distil; should it prove obstinate in not closing, it may be touched with a heated wire. And sometimes also, when the urine is unusually slow of coming by the urethra, this may be expedited by the occasional introduction of a catheter or bougie.
It is not often that the operation of lithotomy requires to be repeated. In some few cases, however, the calculous diathesis continues, a new concretion is formed, and the patient again applies for relief, perhaps several years afterwards. In such circumstances, the incisions are to be made in the right side of the perineum; for the track of the former wound is now consolidated, firm, and hard, and would be cut with difficulty. But when, from neglect or want of dexterity, the first operation has been imperfectly performed, one or more stones being left behind, the wound may not heal, nor even contract to any considerable extent; and then dilatation of the existing opening, with fresh section of the prostate, will probably be sufficient, though at an interval of many months.
It has been proposed to divide the operation into two parts, with an interval of several days between; first to make the incisions, leaving the stone undisturbed, and after suppuration has been fairly established, and the parts become relaxed, then to extract the foreign body, provided it have not in the mean time been discharged spontaneously—in short, to perform the operation _à deux temps_. This method is liable to serious objections. Two operations must in general be more severe than one. The patient is rendered despondent and miserable after the first, by knowing that the object of his suffering has been imperfectly accomplished, or rather not accomplished at all. Much, and often serious irritation is produced by the wounded bladder being contracted on the hard and rough foreign body; patients have sunk under this torture, and the cure is always tedious. From the earliest times it has been quite well understood, that when the stone cannot be got out it must be left in; but the proposal of always leaving it in, on principle and not from necessity, is really absurd. There is room for suspecting that this mode of operation originated as a virtue from necessity; the extraction of the stone is always the most difficult part of lithotomy, requiring much skill and dexterity, and the operator, finding himself baffled in his attempts to effect it, wisely desists from his futile efforts at the time, and waits for another opportunity. This is certainly better practice than the using of much force, or dilating the wound by incision to a dangerous extent, but it is very far from being so good as the immediate removal of the foreign body, smoothly and quickly, skilfully, and without violence; and it has been already observed, that the cases are very few indeed in which the stone cannot be removed through the prostatic opening without the employment of any force, and, without inflicting any injury to the parts through which it passes—without hazard and without delay. The sooner the method _à deux temps_ is expunged from the list of surgical operations, the better will it be for suffering humanity and the credit of our art.
In those rare cases in which the stone is so large that it cannot be brought through the outlet of the pelvis, it must either be broken into fragments, or removed entire through incision above the pubes; as already stated, it is probable that the _high operation_ is the safer proceeding. It is, however, an operation attended with much danger. The wound is necessarily extensive, and important parts are liable to be interfered with; and, from not being dependent, the escape of the urine by it is almost certain to cause infiltration of the cellular tissue surrounding the bladder—an occurrence almost always proving fatal and that rapidly. The first part of the procedure is to insure distention of the bladder, so that it may rise in the pelvis, and afford sufficient space between its lower part and the anterior reflection of the peritoneum; but this may prove either very difficult or altogether impossible, even with the aid of injection by the urethra, in consequence of the unyielding contracted state of the viscus, and the great thickening of its coats. An incision is made through the integument and fatty matter, from three to four inches in length in the mesial line, and terminating over the symphysis pubis; the recti and pyramidal muscles are then separated, the cellular tissue cautiously divided, and the fore and lower part of the distended bladder exposed. The coats are pierced at the most inferior part, and an opening made sufficient for the introduction of the finger. By the finger the dimensions of the stone are ascertained, and then the wound is enlarged upwards to such an extent as will by dilatation admit of the extraction. Forceps are introduced, of sufficient length and grasp, and the foreign body removed without laceration or bruising of the parts. The patient is then laid on his side, a piece of dressing being interposed between the edges of the wound to favour the discharge of the urine externally. The escape of this fluid maybe free and copious, and the wound may close favourably; but the majority of the patients on whom this operation has been performed, have perished either from urinary infiltration, from peritoneal inflammation, or from exhaustion. Fortunately, I have never had occasion to resort to it.
It has been proposed to combine this mode of operation with wound of the posterior part of the urethra from the perineum, in order that a free and depending outlet may be afforded to the urine, and also, that by introducing instruments into the bladder from the lower opening, the organ may be elevated and stretched so that its fore part may afford sufficient space for the high incision without danger to the peritoneum. With this view the perineum is incised, similarly but to a less extent than in the lateral operation, and the membranous part of the urethra opened. Through this aperture the sound with a stilet for elevating the bladder is passed, and intrusted to an assistant; the incision above the pubes is then made, the stone extracted, and a tube is left in the perineal wound for discharge of the urine. The plan, though complicated, appears feasible, and likely to diminish hazard by preventing infiltration.
