In excising the prolapsed portion I prefer to remove one or more V-shaped portions on opposite sides and bring the edges together by sutures. This is preferable to clipping off the whole of the protruding mass, because the cicatrices left are less likely to give after trouble.

When the dilatation is caused by varicose veins it may be well to follow the example of Gustave Simon. He exposed the vessels by cutting through the vaginal wall, ligated the largest, and arrested the hemorrhage from the smaller ones by applying liquor ferri perchloridi. He repeated this operation several times on the same patient, who experienced little or no inconvenience from the proceeding and made a good recovery.

Dilatation of the lower third of the urethra is usually secondary to some other trouble, as I have already stated; and all that is necessary to do for such cases is to remove the cause and treat any inflammation that may exist. The dilatation will then disappear; and if it does not, but little if any trouble will be caused by it.

The treatment of dilatation of the upper third consists simply in supporting the parts. This can be effectually done by using the pessary already recommended for the relief of prolapsus of the bladder. It may be necessary to have the instrument so formed as to bring the pressure where it is required. This is done by placing the pessary in position and observing what change of form, if any, is necessary, and then directing the instrument-maker to make the alteration. If the parts are well supported in this way, recovery will follow unless atrophy of the muscular wall has previously taken place. Even then the patient can be kept comfortable by wearing the pessary. If there is urethritis present, it may be necessary to remove that before using the pessary; otherwise the pressure of the instrument may cause pain and aggravate the inflammation.

In dilatation of the middle third Bozeman has proposed to make an opening into the most dependent part of the urethra through the vaginal wall, and maintaining it until all inflammation has been relieved, and then closing the opening by the usual plastic operation. By this means the urethra is perfectly drained of urine and the products of inflammation which accumulated there before. This, with appropriate cleansing and topical applications, soon restores the mucous membrane to its normal condition, and the removal of the redundant tissue during the operation of closing the opening effectually cures the whole trouble. This treatment is admirably adapted to marked cases of long standing, and should be employed. By using the thermo-cautery to make the opening the operation is easily performed. In recent cases of less magnitude I have obtained satisfactory results by dilating the lower part of the urethra and supporting the dilated portion either with a pessary or a tampon of marine lint. This permits the urethra to keep itself empty, and then, by frequently washing it out and applying such remedies as will cure the urethritis, recovery will sometimes follow.

Dislocations of the Urethra.

This is one of the affections most frequently met with in practice. I have found very few cases recorded in medical literature. This neglect of the subject by authors is perhaps due to the fact that in many cases of displacement of the urethra the bladder is also dislocated, and the whole trouble is described under the head of vesicocele or cystocele. Now, it is true that displacement of the two occurs together, but either may take place alone.

The extent of displacement varies exceedingly, but I shall describe only the partial and the complete. A clear comprehension of these two degrees will cover all intermediate forms. In partial displacement downward the upper two-thirds of the urethra are prolapsed, so that the direction of that portion of the canal is backward, instead of curving upward, as in the normal condition. In complete prolapsus the urethra runs from the meatus (which is in its normal position) backward, and rests upon the perineum, or in extreme cases, accompanied with prolapsus of the bladder and uterus, its direction is backward and downward, the position of the vesical end of the urethra being below the level of the meatus. In this degree of displacement the urethra and bladder can be seen presenting at the vulva or lying between the labia minora. The urethra is usually shortened considerably when the prolapsus is marked.

ETIOLOGY.—Utero-gestation and delivery are the most important causes of this affection. In the advanced months of pregnancy I have observed that while the bladder rose above the pubes the urethra was pushed slightly downward by the settling of the enlarged uterus into the pelvis. In such cases when labor occurs the head of the child dislocates the urethra still more by pushing it still farther down. This process I have often watched in forceps delivery. When there is a partial prolapsus of the urethra existing before labor, the urethra and anterior vaginal wall are forced down before the advancing head, and that, too, while the attendant is making counter-pressure to prevent it. The displacement produced in this way is often restored during convalescence if proper care be taken to push the parts back into place and the patient is kept at rest until the tissues regain their tonicity. But in many cases the trouble is overlooked, and by permitting the patient to get up and be on her feet while there is still prolapsus it will slowly increase until the dislocation is complete. This will surely be the case if there is any loss of perineum. Indeed, rupture of the perineum is an accident which permits the urethra to descend from its place. The perineum supports the vaginal walls, which in turn support the urethra; and if it be lost, even in part, the vaginal walls become relaxed, or perhaps never regain their tonicity after delivery, and, settling down more and more, carry the urethra with them.

SYMPTOMATOLOGY.—The symptoms arising from displacement of the urethra are much the same as those found in dilatation and other urethral diseases. I need not, therefore, repeat them in detail. Suffice it to say that in dislocation of the upper portion of the canal there is, in addition to frequent urination, a partial loss of control of the bladder. Under the extra pressure of coughing, for example, the urine will escape. This loss of control does not exist, as a rule, in complete displacement. On the contrary, there is usually difficult urination, which requires increased voluntary efforts to empty the bladder. In all degrees of displacement the symptoms are increased in the erect position, and are markedly relieved on the patient's lying down.
