Urinary bladder

“ Where the inconvenience thus detailed is present, the quantity of fluids must by degrees be diminished, the general state of health must be studied. Dieting and warm-bathing are two sheet-anchors, if properly applied. All remedies tending to afford strength to the urinary system must be had recourse to; and where the bladder loses any of its retentive power, I entertain the greatest benefit from an injection.
The next form of urinary disturbance of a proximate nature to the one just described, is also where the urine is discharged in large quantities ”

“ The ureter or duct of the kidney begins at the hilum and descends on the back wall of the abdominal cavity to open into the bladder. It is usually about 12 in. in length and as thick as a goose quill. At its termination it passes obliquely through the coats of the bladder, so that when the bladder is distended:sewn the lumen of its end is closed. The urinary bladder is a membranous bag lying in the pelvic cavity directly behind and above the dorsal surface of the pubes. In the foetus and infant, however, the bladder lies in the abdomen, not in the pelvis. ”

“ Cold air and cold water will increase the quantity of urine by decreasing the absorption from the bladder; and neutral and alcalious salts and cantharides by stimulating the neck of the bladder to discharge the urine as soon as secreted; and alcohol as gin and rum at the beginning of intoxication, if the body be kept cool, occasion much urine by inverting the urinary lymphatics, and thence pouring a fluid into the bladder, which never passed the kidnies. ”

“ The urinary apparatus (consisting of the kidneys, ureters, bladder, and urethra) is known to be the principal emunctory for eliminating and voiding the detritus formed by the continual decay of the parts comprising the animal economy. The urine is this detritus in a state of solution. The components of urine are chemically similar to those of calculi, and as the components of the one vary according to the disintegration occurring at the time in the vital alembic, so do those of the other. ”

“ This collection takes place in the kidney, the ureters (the vessels that convey the urine to the bladder) , the bladder, and sometimes in the urethra. The stone so formed varies in its composition and size, and is one of the saddest ills that can befall human nature. Hence the importance of watching, and attending to every urinary disturbance, of which gravel forms a prominent feature, the treatment of which has been already stated; but which, as it involves more practised judgment than a non-professional invalid can be supposed to possess, had better be intrusted only to professional hands. ”

“ However speedily soap and lime-water may dissolve the greatest part of urinary stones out of the body, yet [215] being mixed with the aliment and humours of the stomach and guts, and afterwards with the whole mass of blood, it is impossible but their force must be greatly impaired before they arrive with the urine at the bladder. ”

“ In many instances, too, the urinary passages are affected, the patient being harassed with frequent, painful and difficult micturition, swelling of the penis, and pain in the region of the bladder, or, if a female, 238with burning pain of the vagina and excoriation of the labia. [618] Sometimes the irritation of the urinary organs is so great as to be attended with total suppression of urine, as in a case related by Guilbert of Montpellier, in which this symptom continued several days. ”

“ Actual retention of urine, that is, urinary secretion passed into the bladder, but retention in the latter viscus by inanition, stricture, or other obstruction, naturally cannot continue any great length of time without mechanically rupturing the vesical walls; but suppression of urine or absolute anuria may last an astonishingly extended period. Of the cases of retention of urine, Fereol mentions that of a man of forty-nine who suffered absolute retention of urine for eight days, caused by the obstruction of a uric acid calculus. ”

“ But if, in spite of such treatment, the incontinence persists, it is better, from an economic standpoint, to treat the urinary eczema with astringents, etc., and quickly to fatten the animal.
EVERSION OF THE BLADDER. Eversion of the bladder only occurs in female animals after difficult parturition. The viscus is turned completely inside out, as occurs in eversion of the uterus, the base of the bladder becoming invaginated in 520the cavity of the bladder itself, and afterwards passing into the urethra and vagina. ”

“ When the part becomes morbidly enlarged, it acts as a mechanical impediment to the passage of urine from the bladder, but from this circumstance we cannot reasonably infer, that while of its normal healthy proportions, its special function is to facilitate the egress of the urine, for the female bladder, though wholly devoid of the prostate, performs its own function perfectly. ”

“ On introducing the catheter sometimes part of the urine will come away and not the whole, which is difficult to explain; but may arise from the weakness of the muscular fibres of the bladder; which are not liable suddenly to contract themselves so far as to exclude the whole of the urine. In some old people, who have experienced a long retention of urine, the bladder never regains the power of completely emptying itself; and many who are beginning to be weak from age can make water a second time, a few minutes after they supposed they had emptied the bladder. ”

“ If at any time he should fail to perform the act of micturition, he ought not to strain, but should quietly wait for a little before making any further effort. Regularity in the times of making water is also of much importance.
Retention of urine may occur in paralysis of the bladder, or in conditions where the patient is suffering from an illness which blunts the nervous sensibility, such as apoplexy, concussion of the brain, or typhoid fever. It is, however, more commonly due to obstruction anterior to the bladder, as in stricture of the urethra or enlargement of the prostate. ”

“ But in every case disease-germs are the cause of the trouble, and they may be found in the urine. The first effect of inflammation is to render the bladder irritable, so that as soon as a few drops of urine have collected, the individual has intense or uncontrollable desire to micturate. ”

“ Independently of which, where so much disease exists as in the urethra, the urine also constantly pressing against ulcerating and irritable surfaces, extravasation of that secretion takes place, and the most formidable and alarming consequences ensue. In the simplest form of stricture, many important functions are disturbed. A very frequent consequence is permanent irritability of the bladder, so that the patient is obliged, ten or twelve times a day, to micturate, and is unable to pass through the night without suffering nearly the same inconvenience. ”

“ When urine contains a larger amount of chemical constituents than it can conveniently hold in solution, a certain quantity crystallizes out, and may be deposited in the kidney or in the bladder. If the crystals run together in the kidney the resulting concretion may either remain in that organ or may find its way into the bladder, where it may remain to form the nucleus of a larger vesical calculus, or, especially in the case of females, it may, while still small, escape from the bladder during micturition. ”

“ In the former case the patient begins to void his urine with tolerable ease; but, as soon as it touches the galled or inflamed urethra, a sudden constriction takes place, and the urine is voided by spurts, sometimes by drops only. When the strangury is owing to an inflammation about the neck of the bladder, there is a constant heat and uneasiness of the part, a perpetual desire to make water, while the patient can only render a few drops, and a troublesome tenesmus, or constant inclination to go to stool. ”

“ SYMPTOMS AND DIAGNOSIS.—Patients complain of difficulty in emptying their bladders, the urine coming away in interrupted jets. They are [p. 349] apt to be irregular in their times of urinating, and are liable in consequence at times to have retention and over-distension. Pain and sometimes a slight cystitis are present. Finally, they completely lose the power of urinating and a catheter has to be used. The diagnosis is to be made as in hypertrophy, by a finger in the vagina and a sound in the bladder. ”

“ Retention of urine is not always present even in those cases in which the limbs are completely paralysed, as the fibres of one side of the cord are sufficient to maintain the functions of the bladder. The patient may be aware that the bladder is full, although he is unable to empty it. Similarly, sensation in the rectum and anus may be retained although the control of the sphincters is lost. ”

“ Many patients find it difficult, even impossible, to void urine during the first several hours after delivery because of the removal of intra-abdominal pressure; the recumbent position and the swelling and bruised state of the tissues about the urethra. The bladder is likely to be less sensitive than usual and the patient will be able to retain an abnormally large amount of urine for several hours without discomfort, or desire to void. ”

“ In the case of some parts of the body, disproportionate development of the part may not give rise to anything further than unsightliness; but when we find the small size of the urethra retarding the free passage of the urine, then we may expect, if this condition is long continued, to find more or less irritation of the urethra and, perhaps, of the bladder, also. ”

“ On the other hand, a man may continue about and at his work with a patient flabby bladder containing constantly more or less stringy mucus and ammoniacal urine, suffering little or no pain or tenesmus, and perhaps having no subjective symptoms except a slight sense of weight in his lower belly and a rather frequent desire to urinate. ”

“ The patient passes urine often in small quantity, and with whines or cries. He walks slowly and stiffly with the back arched, and compression of the abdomen and especially of the prepubian region is painful to a marked degree. The tense elastic bladder may often be distinctly felt through the abdominal walls. The inflamed bladder is liable to paresis and paralysis with great overdistension, and aggravation of the general symptoms, the eyes sunken, and dullness, stupor and coma betraying uræmic poisoning. Some claim rupture of the bladder as is so common in the ox. ”

“ In severe attacks nausea and vomiting are present and the patient is collapsed; sweating breaks out in his face and the pulse is feeble and weak. The pain lasts from an hour to several days, until the stone reaches the bladder, partial suppression of the urine during the attack occurs, but a large quantity of urine is usually passed after it and a feeling of soreness may, be present for several days. The stone may again cause pain in passing through the urethra, or it may remain in the bladder as a nucleus for a bladder calculus (stone) . ”

“ In severe cases, most excruciating pain is experienced during the discharge of the contents of the bladder. The urine is often bloody; in general it is of a milky appearance, containing lymph or puriform matter, and vitiated secretion from the lining membrane. Micturition is almost constant, small quantities being voided at a time. Sometimes the inflammation extends to the ureters and pelves of the kidneys, causing violent pains in the loins, nausea, occasional vomiting, and colicky affections. ”

“ Removal of tonsils and adenoid vegetations might conceivably cure an enuresis which is nocturnal, it cannot account for an incontinence which spreads to the day. We might believe that to distend the bladder by hydrostatic pressure was a cure for incontinence of urine, and that it acted by removing the local cause,—the smallness and contraction of the bladder,—were it not that the loss of control is so apt to spread to the rectum as well. There is no evidence that the urine is peculiarly irritating. ”

“ Some patients keep a catheter and "draw" their own urine. Unless the patient takes great care, the bladder and urethra will be irritated and perhaps infected through neglect of cleanliness. Medicines are not very useful in severe cases. Operation is the only reliable cure especially when some urine is always retained. ”

“ Unless a specialist of experience be consulted, the bladder will most probably be examined, and medicine will be prescribed only to excite the kidneys to secrete more urine, which does harm instead of good; the disease slowly, but surely progressing. Patients often write us that they have had something wrong with the bladder for a number of years, having to urinate more frequently than they ought ”

“ When the urine is too long retained, it is not only resorbed, or taken up again into the mass of fluids, but by stagnating in the bladder it becomes thicker, the more watery parts flying off first, and the more gross and earthy remaining behind. By the constant tendency which these have to concrete, the formation of stones and gravel in the bladder is promoted. Hence it comes to pass, that indolent and sedentary people are much more liable to these diseases, than persons of a more active life. ”

“ If she find an obstruction or stoppage of the urine, by reason of the womb's bearing too much on the bladder, let her lift up her belly a little with her hands, and try if by that she receives any benefit; if she finds she does not, it will be necessary to introduce a catheter into her bladder, and thereby draw forth her urine. If the difficulty be from the ill posture of the woman, let her be placed otherwise, in a posture more suitable and convenient for her ”
