DIAGNOSIS.—An examination of the vagina, either by touch or speculum, will reveal the downward projection of part or all of the urethra, which will show that there is either dilatation or prolapsus. The change in the direction of the canal will be shown by passing the sound, and dilatation can be excluded by observing that the urethra grasps the instrument firmly at all points. In dislocation of the upper two-thirds of the urethra the sound passes in the normal direction, but is arrested at a half or three-quarters of an inch from the meatus; but by pushing up the vaginal wall and the urethra the sound will then pass into the bladder. When the prolapsus is complete the instrument passes in easily, but takes a downward and backward direction.
PROGNOSIS.—Uncomplicated displacement of the urethra can be remedied in the great majority of cases. By placing the parts in proper position, and holding them there, the relaxed tissues will usually contract sufficiently to support themselves. Should they fail to do so, the patient can at least be made comfortable by wearing some supporter.
TREATMENT.—When the displacement of the urethra is caused by any other trouble, such as defective perineum or prolapsus uteri, then these things should first be attended to. Should there be urethritis, that also should receive appropriate treatment. But the chief indication is to retain the urethra in place; and this can be easily accomplished by using the pessary which has been recommended for supporting the prolapsed bladder. Prolapsus of the upper part of the urethra can be relieved in this way quite satisfactorily. When the whole urethra is displaced, this pessary, while it supports the upper part, will still permit the middle portion of the urethra to settle down. This difficulty may be overcome by making the anterior portion of the pessary long enough to engage in the introitus vulvæ, and in that way keep the whole canal where it should be. Should this cause the patient much discomfort, a tampon of marine lint should be used to keep the parts in position until some restoration of the parts is obtained, and then the pessary will complete the treatment.
Prolapsus or Inversion of the Urethral Mucous Membrane.
The prolapse may be limited to one side or extend all around the canal. The size and extent of the protrusion vary considerably. If the meatus is of full size, the prolapsed portion will usually preserve its natural color for a time; but after a little, from chafing when wet with urine, and especially if not kept clean, it will become red and oedematous. When the meatus is small these changes occur sooner and in a more marked degree, because the prolapsed portion is partially strangulated. The longer the membrane remains exposed the more sensitive it becomes, and the frequency of urination and pain attending it increase. It also becomes very tender and painful to the touch. In marked cases the ordinary movements of the body irritate the parts, and in that way render walking painful.
These are symptoms that closely resemble those of irritable growths at the meatus urinarius, and, so far as history is concerned, it is not easy to make a differential diagnosis. To do this it is necessary to make a local examination. The physical signs and the points in the diagnosis between this affection and other diseases have been given briefly but sufficiently under the head of Dilatations of the Urethra, and need not be repeated here.
The causes of prolapsus of the urethral mucous membrane are numerous, but those that are best known are long-continued congestion of the membrane, urethral and cystic irritation causing frequent urination and vesical tenesmus. Chlorotic and greatly debilitated women are said to be predisposed to it, as also old prostitutes. The few cases that I have seen were in women over fifty years of age, and all of them were weak, nervous patients who had suffered from some organic disease or functional derangement of the urinary organs.
PROGNOSIS.—This disease does not yield promptly to mild treatment, unless it is seen early in its progress; and if it does yield to mild, soothing, and astringent applications, it is liable to return. But in case there is no other disease present that tends to keep it up, it can usually be cured by surgical means.
TREATMENT.—When a case is first seen it is well to remove any inflammation or other complicating conditions. The prolapsed membrane should be replaced, and the patient kept quiet in bed to favor the retention of the parts in situ. Astringents, such as tannic acid, alum, or persulphate of iron in a weak solution, should also be used. Should these fail, the prolapsed portion of the membrane should be removed. The methods of doing this (by excision and the thermo-cautery) have already been described.
