When the instrument has been fairly lodged in the bladder, it is to be retained. A tape is attached to each of the rings at the neck of the catheter, is brought under the thigh, and fastened to a bandage passed round the waist; this simple retentive apparatus is quite effectual, and suits the erect as well as the recumbent posture. A peg, of metal or wood, is placed in the mouth of the catheter, that the patient may be kept dry, and at the same time have it in his power to relieve the bladder as often as necessary. The instrument should be retained for twenty-four hours at least, and, if the patient can bear it, for forty-eight, or even more. At first it occasions considerable uneasiness, pain, and excitement, but these gradually subside; when severe, they may be allayed by opiates. The parts make efforts to get rid of the foreign body, and these efforts are salutary. Discharge takes place from the membrane, and oozes by the side of the catheter; relaxation occurs, often to a very great extent; and, on moving the handle of the instrument, it is found to be not only less firmly grasped, but to possess considerable freedom of motion in the contracted part. Thus a most successful inroad is made upon the disease, and the after treatment thereby happily abridged. The instrument is withdrawn, and time afforded for the parts to become quiet. After the lapse of two, three, or four days, according as the uneasy feelings disappear, a larger instrument is introduced, and retained perhaps for half an hour; and the successive introduction of instruments—sounds being now adopted—at proper intervals, and in proper graduation, is continued as in ordinary cases. Sometimes, though rarely, the good effects of the first introduction and retention of the instrument quickly disappear, the stricture becoming tight and unyielding as before; when this takes place, the practice is to be repeated, but not till after several days, and then the instrument will be retained with advantage for a longer time than before, provided no untoward symptoms are caused by its lodgement. There are very few strictures, indeed, which will not yield to this treatment, when judiciously planned and perseveringly followed.

Fistulous openings generally close in a short time, when once the urethra has been widened. Their contraction may sometimes, however, prove slow and imperfect, even after the stricture has been entirely removed, and the application of the cautery may be requisite; to accomplish this, when the opening terminates in the rectum, a speculum ani is required, by which to view the aperture, and ascertain its site, and along which to pass the heated wire with safety to the bowel. The cautery is not to be applied so as to produce an extensive slough, and much loss of substance, but lightly to the edges. On the separation of the superficial eschar, the margins are raw, excited, and swollen, with a disposition to granulate; and during cicatrisation of the sore, considerable contraction takes place, independent of the formation of new matter. After the contraction thus effected has occurred to its full extent, and not before, the cautery is reapplied; and by a few repetitions of the instrument at long intervals, the opening is brought to close.

At one time attempts to destroy the contraction of the urethra, by the application of caustic to the stricture, were in great vogue; but the total inefficiency of such practice is now generally acknowledged. The armed bougie was in many cases applied hundreds of times, at considerable intervals; and the mode of treatment, though trying, tedious, and hurtful to the patient, must have proved useful to the surgeon—but to him alone. Years were spent in such trifling, and not unfrequently serious consequences followed this treatment, or rather neglect, of the disease. Cutting catheters are dangerous, as well as inefficient for the cure of stricture; thrusting at the end of a long stricture can avail but little, and in the hands of most practitioners the instrument is as likely to perforate the coats of the urethra as to enter the stricture.

Incision of stricture may be required in retention of urine, scarcely otherwise. The practice is noticed under the treatment of retention. In stricture anterior to the scrotum, it is well to avoid incision, if possible, as it generally is so, for a wound there is healed with difficulty, if at all.

_Retention of Urine_ is not to be confounded with _suppression_ of the secretion from the kidneys, arising from disorder of the structure or function of these organs. The kidneys perform very important functions in the animal economy, and complete suppression of their secretion under any circumstances is a very suspicious and dangerous occurrence.

In the healthy state of the urinary organs, when the powers of each correspond, the urine passes without almost any exertion on the part of the patient; the action of the levator ani and abdominal muscles is scarcely required. But when either structure or function is disordered, the balance between the parts is upset; additional assistance is necessary for expulsion of the contents of the bladder. The symptoms of retention differ according to the state of the parts and the cause which has induced it. The bladder varies in size, and in distensibility. In some cases the organ yields readily to the accumulation of fluid within it, rising high in the belly, reaching even the umbilicus, and forming a large, oval, tense, fluctuating swelling, apparent to the most careless and casual observer. The swelling and fluctuation are in such circumstances so distinct, that the disease has actually been mistaken for ascites. Again, all the symptoms of retention may exist, and all its bad consequences result, without any apparent swelling of the abdomen. But then the distended bladder can always be felt by the finger introduced into the vagina or rectum; indeed its posterior fundus bulges in towards the cavity of the gut, in every case, before it ascends upwards in the abdomen. Sickening and agonizing pain, with great anxiety and ineffectual straining, generally attend distention of the bladder to any great degree. When the distention is allowed to continue, urinous fever supervenes, the circulation is accelerated, the patient perspires profusely, and exhales a urinous odour; delirium comes on, followed by sinking, and, if the cause is not removed, coma terminates the distressing train of symptoms. In other instances the painful feelings subside after some time, and the urine is discharged involuntarily from the urethra. The ureters lose the valvular structure of their vesical terminations, and become dilated; the pelvis and infundibula of the kidneys also enlarge, and all are distended by the accumulating urine. On relieving the bladder artificially, the pressure is taken off the secreting part of the kidneys, their secretion is generally renewed with great vigour, and the bladder is again filled rapidly. If the bladder is not relieved the secretion of urine is suppressed.

In many cases the urethra—the bladder more rarely—sloughs or ulcerates, unless preventive measures are adopted, and extravasation of urine takes place into the cellular tissue of the pelvis, of the perineum, of the groins, of the lower part of the abdominal parietes—into the cellular substance of the scrotum, and of the penis—the parts infiltrated depending of course on the point at which the urinary canal has given way. Under such circumstances the patient is sometimes rapidly destroyed, the extravasated urine appearing to induce speedy sinking, similar to the effects of inoculation with a most virulent poison. If the urine escapes into the cavity of the abdomen, the patient inevitably perishes, and that very speedily; and when the cellular tissue of the pelvis is the seat of the extravasation, little hope can be entertained of recovery, though the fatal termination may not be so rapid as in the former case. When the urine is effused into more external parts, as into the perineum or scrotum, the danger is also imminent, if the fluid is allowed to accumulate and become extensively infiltrated; but when it freely escapes externally, either spontaneously or by incision, there need in general be no great apprehension of immediate danger. In such cases the aperture in the urethra is found to be at first irregular and ragged; afterwards its inner surface becomes rounded off, and a papilla presents externally. The infiltrated cellular tissue is dark, fetid, broken down, and soft, sometimes seemingly in part dissolved by the putrescent urine; and, when the patient has survived a considerable time, it frequently resembles closely in appearance a portion of suppurated lung. When active practice is not adopted after extravasation of urine has taken place, the cellular tissue around sloughs along with the integuments; rapid depression of the powers of life ensues, with great disturbance of the sensorial functions. Death very soon relieves the patient from his sufferings; some few struggle through, and recover, after losing the coverings of the penis, of the testicles, and of the perineum.

The causes of retention are many; but the surgeon must know them all, as the treatment must vary according to the cause. They may be divided into such as weaken the power of expulsion, and into such as impede the progress of the urine in the urethra.

Retention of urine is caused by paralysis of the bladder, from over-distention, from injury or disease of the spinal chord, from pressure on the spinal chord or nerves. In such cases the bladder often attains a very large size. At first the accumulation produces all the uneasy symptoms formerly mentioned, but after some time these subside, and the urine drains away according as it is secreted, without, however, the original accumulation and tumour being diminished. This state of the urinary system is very common in old people, who neglect natural calls to empty the viscus during the night, or while sitting socially after dinner. The uneasiness gradually goes off, and when they at length think of making water, none can be got to flow. Sometimes they remain in this state—the bladder full, and becoming more and more distended—for days, drinking gin and water, juniper tea, or other popular remedies. Incontinence then takes place, and the dribbling of the urine affords considerable relief; this state of matters is often allowed to continue for weeks. Thus the power of expulsion may be lost for ever, though sometimes it is regained even under very unfavourable circumstances. I recollect attending a man upwards of eighty, labouring under retention of urine with incontinence, and whose bladder required relief by the catheter for ten or twelve days; at the end of that period the bladder regained its expulsive power and retained it; and cases are on record in which the power of expulsion has returned after the lapse of several months. Retention thus induced is often complicated with disease of the prostate gland or of the urethra. The patient, perhaps, has been for a long time incapable of emptying his bladder completely; a portion of the urine always remains in the most dependent part of the viscus, and the quantity retained becomes greater and greater, until from some slight cause the power of expulsion is lost entirely. In these cases the bladder, though much increased in capacity, is also much thickened.

Retention from inflamed urethra, attended with swelling and spasm about the neck of the bladder, is preceded by hardness and tenderness in the course of the urethra, and a smarting felt when a drop of urine passes along. Retention not unfrequently takes place during gonorrhœa, from the dread which the patient has of making water; and from the swelling of the lining membrane.

Retention from abscess in the perineum was formerly noticed.

Retention from injuries in the perineum. The urethra is either severely bruised, perhaps lacerated, or torn completely across; and if the patient attempts to make water before proper means are adopted, blood and urine are extravasated into the cellular tissue exterior to the canal. In cases of slighter injury, retention may occur on account of the inflammatory swelling of the parts supervening secondarily.

Retention from stricture of the urethra is of very frequent occurrence, and most difficult to manage. The state of the urethra and bladder in this disease has been already adverted to, but it is necessary to bear in mind the thickening of the latter, and the dilatation which uniformly takes place behind the stricture. All the urgent symptoms of retention may, in this case, arise from the accumulation of but a few ounces of urine. The bladder contracts frequently and very forcibly, causing great suffering. Temporary relief is experienced when the urethra gives way by ulceration, and the urine becomes extravasated into the cellular texture; the patient gets up, and, if in the dark, thinks that the stricture has yielded, and that he is passing urine naturally. But soon he feels a glowing heat in the perineum; the parts swell and become livid; violent constitutional symptoms come on, the discoloration advances, the integuments slough, ill formed matter is discharged, and disorganised cellular tissue mixed with putrid sanies is exposed. The parts exhale a urinous odour, which, when once smelt by the practitioner, can never afterwards be mistaken. Occasionally œdematous swelling of the penis takes place, particularly of the prepuce, when it has been pulled at and bruised during the patient’s efforts to make water, and this must not be confounded with infiltration of urine; I have seen it occur some time after the bladder had been relieved by the catheter. Infiltration of putrid serosity into the cellular tissue of the prepuce, the subcutaneous tissues of the penis, scrotum, and lower part of the abdomen, occasionally also takes place to a great extent, after the bladder has been relieved by the catheter, the coverings are destroyed, and the patient may, even despite of active treatment, perish in consequence. In such cases, a small quantity of urine may possibly have escaped into the cellular tissue before the bladder has been relieved, so as to commence the mischief.

Retention from the lodgement of calculi. Temporary obstruction to the flow of urine is sometimes experienced from calculus in the bladder. Complete and fatal retention has arisen from calculi having become impacted in the urethra, and been allowed to remain there, blocking up the passage entirely.

Retention from affections of the prostate gland and neck of the bladder, inflammatory or indolent. In acute inflammation of the prostate gland and cervix vesicæ, the other parts around swell, the mucous membrane becomes turgid, and the mucous secretion is increased. Suppuration may take place, and an abscess, chronic or acute, form in the substance of the gland, or in the cellular tissue exterior; the parietes of the abscess may give way, and the matter discharged into the bladder, into the rectum, or into the cellular tissue of the perineum. Bloody and mucous discharge from the urethra, frequent desire to make water, sudden stoppage of the urine whilst making water, pain in the glans penis, and other symptoms of stone in the bladder, followed a fall on the back. Afterwards, a tumour pointed into the rectum, and was opened; purulent matter was profusely discharged, and afterwards urine escaped through the aperture. The patient died in three weeks, from irritative fever, with gastro-enteritic symptoms. Along with thickening of the bladder, and disease of its mucous coat, there was found a large abscess of the cellular tissue, communicating with an abscess in the third lobe of the prostate gland, and that with the cavity of the bladder.

When the affection is less acute, the prostate slowly enlarges, from opening out of its texture, and deposition of new matter in the interstices, it becomes hypertrophied. The whole gland may enlarge uniformly, but generally one part protrudes more than the others. When the third lobe enlarges, it necessarily projects into the bladder, or into the prostatic portion of the urethra, and there, acting like a valve, causes much more formidable obstruction to the flow of urine than does enlargement of the lateral lobes; the obstruction is the more complete the greater the distention of the bladder. At first, this lobe is but slightly prominent, and of a conical form; but as it enlarges, its regularity of shape disappears, the tumour is nodulated, and in general somewhat pyriform. It occasionally projects to one side of the passage. The affection is seldom met with, unless in old people.

In consequence of prostatic enlargement, pain is felt in the perineum, with occasional throbbing, and a sense of weight; there is frequent desire to make water, the bladder is irritable, and discharges ropy mucus. There is more or less irritation of the lower bowels; there is an almost constant desire to empty the rectum, from a feeling of fulness there, and pain, often severe, is felt on going to stool; when the enlargement is great, the bowel is considerably compressed, and the feces, when solid, are passed flattened like portions of tape. Frequently there is thin mucous discharge from the urethra. In making water, the urine, as it were, hesitates, and after a while passes away, at first in drops, and afterwards in a scanty and irregular stream; pain is felt at the point of the penis, in the loins and hips, and often in the inside of one or both thighs. On attempting to pass the catheter, its extremity is obstructed in the prostatic region, and the swelling can be felt by the finger introduced into the anus. Examination of the tumour, per anum, is very often a painful proceeding; it is best accomplished after a catheter or sound has been introduced. The disease is often coexistent with calculus in the bladder. The tumour is very seldom malignant, but proves both troublesome and dangerous from its size. The bladder may become distended in consequence, though retaining the power of partially relieving itself; or the urine may come away involuntarily after some time; or retention may be complete, and, if not relieved, the bladder may slough.

It is to be recollected, that in retention of urine, from whatever cause, and particularly in that arising from prostatic enlargement, the urethra is elongated, and the bladder rises into the abdomen like the gravid uterus. The reason of such change of relative situation is sufficiently obvious, being chiefly mechanical.

Fungous, or other tumours, furnishing blood or vitiated puriform matter, now and then grow from the internal surface of the bladder, unconnected with the prostate gland. Worms, too, occasionally lodge in the bladder. Either of these circumstances may induce retention of urine. Another cause of obstruction is hernia of the bladder.

There is no disease in which the patient is more liable to be ‘bungled out of his life,’ than in retention of urine. Great credit is to be gained by judicious and skilful management of the various stages, and by expert use of the catheter in difficult cases, when other practitioners, perhaps, after being foiled, have proposed operations alarming to the patient, and, in themselves, dangerous. In no disease are patients more grateful for relief, for in this the agony is often unbearable. Immediate abatement of all painful symptoms follows skilful and prompt measures; and the superior science of one man over others is made apparent to the most ignorant observer. In over-distended bladder from paralysis, the catheter can in general be passed without difficulty. It should be of a large size, and its introduction should be repeated as often as nature calls for relief, perhaps three or four times during the twenty-four hours, until the viscus regains its tone; and this, unless irrecoverably lost, will generally be restored in a few weeks at most. Repeated introduction of the instrument is here preferable to the retaining of it; the latter measure should always be avoided, unless absolutely indispensable, for a foreign body lodging in the urethra and neck of the bladder must always be a source of more or less irritation; and experience shows that the bladder sooner recovers its tone when the instrument is introduced only to draw off the urine, when the uncomfortable feelings of distention come on, than when it is constantly retained. The patient soon learns to pass the instrument himself, and thereby saves the surgeon from frequent attendance, whilst, at the same time, the bladder is opportunely relieved. Stimulants, as the tinctura lyttæ, given internally, with external friction, blistering, and the application of strychnine to the raw surface, may contribute towards restoration of the muscular power of the organ. Injections into the bladder have been recommended, but are both hurtful and inefficient. Enemata, containing turpentine, or other stimulating fluids, are of service.

In retention from inflamed urethra, the catheter should, if possible, be dispensed with. The introduction of it is excruciatingly painful, and will certainly aggravate the original affection. Blood should be abstracted both from the system and from the perineum; fomentations, with the warm bath or the hip bath, are afterwards to be employed. The retention is usually induced by hard exercise, or intemperance in living; these of course must be abandoned, and their opposites enjoined. Camphor alone, or combined with opium or hyoscyamus, is to be given internally in large doses. Opium may also be useful, administered in the form of an enema or suppository. If relief is not soon afforded by such soothing measures, the bladder must be relieved by the catheter; and if the surgeon be foiled in the introduction of this, as he ought not to be, the only resource is to puncture the bladder from the rectum—a harsh measure, to be sure, and one not indicative of surgical talent, but still preferable, in the eyes of both patient and practitioner, to death.

In retention from abscess in perineo, a little delay is allowable under the employment of palliatives, when the affection is acute. The abscess must be freely opened as soon as its seat is discovered; and until the evacuation of the matter, the use of the catheter should be deferred if possible. In cases of chronic abscess, the catheter must be used, and does no harm.

In retention from injury of the perineum, the catheter should be passed before the patient attempts to make water, and the instrument must be retained; thus extravasation of urine in addition to the blood into the cellular tissue will be avoided. If extravasation has occurred, the perineum, scrotum, or other parts, must be freely incised wherever the urine has been effused, in order to prevent the direful effects of lodgement of that fluid; and then the catheter should be passed and retained as in the former instance. If the surgeon be foiled in introducing an instrument, as he may be, and if the prostate be sound, the bladder must be relieved by puncture from the rectum.
