Chapter LVI: The Male Genital Organs (2)

The other benign and simple tumors, especially _fibromas_ and _chondromas_, are occasionally met, and I have described one rare case of large _lipoma_ within the limits of the testicle proper.

=Cancer of the Testicle.=--This includes, usually, sarcoma, developing from the mesoblastic elements, although adenocarcinoma may be met here, but as an extension from some growth occurring first in the skin or in the immediate neighborhood. Deep cancer in this region is difficult to at first distinguish from the induration produced by tuberculosis or syphilis. In doubtful cases the therapeutic test may be tried in order to differentiate it from the latter. From the former it is usually separated by its more consistent and regular (_i. e._, its less nodular) character. In all three cases the lymphatics of the groin may be early involved, or perhaps not until late. As a rule cancer is met in the later years of life, while the other conditions are more frequently seen in the first half. In the more rapid cases there will be considerable pain, with dilatation of the scrotal veins, and evidences of constitutional involvement. Sarcoma may grow rapidly and metastasis is almost invariably to the lungs.

Of tumors in the testicle, as of those in the breast, it may be said that any new-growth which tends to enlarge, become more dense or adherent, to spread, or to be accompanied by lymphatic involvement _should be removed_; no mistake will be made in applying this rule in these cases, especially if by the therapeutic test or otherwise syphilis can be excluded. Malignant disease sometimes travels rapidly up the cord, and the main fear is not so much of local recurrence as of deep involvement within the pelvis. Cases of cancerous growth of the testicle should be not only thoroughly extirpated from the scrotum, but the _inguinal canal should be opened, and the cord followed as far as possible and completely removed_.

Cases may arise where amputation of the scrotum may be justifiable for the purpose of temporary relief, in order to avoid discomfort, hemorrhage, or offensive ulceration.

HYDROCELE.

Strictly speaking the term hydrocele means accumulation of watery fluid in any pre-existing cavity. By universal consent, unless some other cavity be specified, the tunica vaginalis is understood. The consequence is a more or less distended sac of serous fluid, which first occupies a position in front, but finally is spread around the lateral portion of the testicle, and may form a tumor the size even of the individual’s head. It is an innocent collection of serum, but the walls of such a sac will be thickened in proportion to its age and size, and may in the course of time undergo such degenerations as the calcareous, for instance, by which it becomes more or less infiltrated or encrusted with calcareous material. Thus I have in my possession a tumor of this kind, nearly the size and almost as hard as an ostrich egg, the old tunic being converted practically into a shell.

_Acute hydrocele_ occurs, as above mentioned, in connection with the acute infections, but is then ordinarily a matter of but a few days or weeks.

Hydrocele, as usually implied by the term, is an exceedingly chronic and almost painless affection, which may follow injury, but which comes often without any known cause. Many theories have been advanced to account for it, but none are generally satisfactory. These cases, however, occur usually after the fortieth year of life, but may be seen in the young. Their greatest unpleasantness is that produced by the weight of the mass as it drags upon the cord and the scrotum.

The tumor is pear-shaped, and abruptly circumscribed at its upper limit, below the external ring (unless there be also involvement of the cord), and gives no impulse when the individual coughs. By these features it is distinguished from hernia, for which it is often inexcusably mistaken. A hernia is a distinct prolongation from above, whereas a hydrocele terminates below the hernial outlet, and by its smaller extremity. The distended sac will fluctuate, and will return clear fluid upon puncture with a hypodermic needle, and is so translucent that light may be transmitted through it when it is interposed between a candle-flame and the surgeon’s eye. (Serious thickening of the sac may interfere with the value of this test.) A congenital form of hydrocele is also known, due to failure of obliteration of the canal of Nuck, and it might be possible in some such cases to get a slight impulse on coughing, as when the sac connects with the abdominal cavity, in which case it should be possible to gently press its contained fluid back into the abdomen above. In most congenital cases there is a tendency to spontaneous cure, at least to obliteration of the canal.

Occasionally both sides are involved, or the sacculation may be multilocular, or accompanied by cystic extensions along the cord.

=Treatment.=--In regard to methods of treatment, but two will be considered here, _aspiration with injection of carbolic acid_, and _extirpation_. The former consists in the insertion of an ordinary (small) trocar, which is thrust in from below upward, care being taken that its point avoid the testicle, which is always found to the posterior and inner side of the sac. Through this trocar the contained fluid should be completely evacuated, so that the sac is practically dry. Into it is now injected with some force from 2 to 6 Cc. of absolutely pure carbolic acid, after which the trocar is instantly withdrawn, pressure made upon the opening, and massage made upon the scrotum and the contained testicle, in order to distribute the acid freely over the serous surface. Its effect is to completely sear the entire surface so that the mouths of all the absorbents are closed. In this way danger of carbolic poisoning is quite avoided, a danger which would be imminent were the acid reduced in strength. But little pain is caused by the procedure. Its immediate effect is to produce exudate, with some recurrence of swelling, which ordinarily rapidly absorbs, while the exudate, coagulating, serves to produce obliteration of the cavity of the sac. This is the carbolic method of Levis, who introduced the acid as a substitute for the iodine formerly employed, upon which it was a great improvement. For cases of moderate age, whose sacs are not too thick, it often proves satisfactory. Having failed, or the case being considered not adapted to it, the other method is that by open incision and extirpation.

This _open method_ consists in making an incision through the skin, down upon and into the sac, which, being thus instantly evacuated, will collapse. It is now possible to make a more or less complete enucleation of the sac wall, stripping it from the external tissues to which it adheres, as it is not necessary to separate it from the testicle itself. It has been found that when the major portion is thus removed the condition is effectually combated. The cavity may be drained with silkworm strands or with a small tube, but only for a short time, if the technique have been correct.

THE SPERMATIC CORD.

The cord participates essentially by its contained _vas deferens and lymphatics_ in the consequences of acute and chronic infections, travelling in either direction, and thus it may be involved in _tuberculous_, _syphilitic_, or _malignant disease_. These expressions, however, are secondary and the conditions have been described above. _Encysted hydrocele of the cord_ implies simple dilatation of an incompletely obliterated canal of Nuck, by which there may be formed along the cord one or more cystic expansions, causing tumors rarely attaining a size greater than a pigeon’s egg, which are innocent collections of fluid, corresponding to the ordinary hydroceles that may occur below. They are ordinarily not difficult of recognition, and are the most common form of neoplasms occurring in this region. They are amenable to the same treatment as that described for hydrocele.

Varicocele. (Hartmann.)]

SPERMATOCELE.

Spermatocele implies a cystic tumor in whose contained fluid, no matter what its source, are found spermatozoa, which may be seen alive under the microscope if examined immediately after removal. Spermatoceles are usually found at the lower end of the cord and in close connection with the testicle. Their occurrence is not uncommon, but somewhat difficult to explain, for it implies connection, at least at some time, between the structures of the cord and a more or less displaced seminiferous tubule. Spermatoceles are rarely diagnosticated as such until aspiration or evacuation and examination of their fluid contents, which usually are of a milky appearance. In general they are to be treated like any other cysts, and by the same methods.

VARICOCELE.

This exceedingly prevalent affection is the result of a varicose condition of the pampiniform plexuses and of the spermatic veins. It occurs in perhaps 10 or 12 per cent. of adult males, rarely before puberty, and almost invariably upon the left side, varicocele upon the right side being as rare as 1 in 500 cases. Its confinement to the left side is explained partly by compression of the left spermatic veins beneath an overloaded and distended sigmoid, and by the disadvantage at which the blood current from the left spermatic vein empties into the vena cava, this being on the left side at a right angle, while on the right the angle is oblique. It has occasionally to do with accident or injury, as well as with occupation or habit. It occurs more frequently in those who are long in the saddle and in those who ride the bicycle to excess. (See Fig. 674.)

Varicocele is usually of slow development, and discovered finally by accident or by attention being drawn to these parts through quack advertisements or misleading statements. The effect is to produce an elongated mass of varicose veins, often described as feeling like a “bag of angle worms,” occupying the lower portion of the cord and extending down upon the back of the testicle. In the more advanced cases the condition can be traced almost to the external ring, but is always more marked low down than higher up. Sometimes it is so extreme that the entire group of veins corresponds in bulk to a hen’s egg; ordinarily it is but a fraction of this size. The consequence is increase of weight and production of dragging sensation upon the cord, often referred to the back, and displacement downward of the testicle, with consequent elongation of the scrotum, which may so greatly relax that it appears to be twice its normal length and contains this varicose mass at its lower extremity. Such a condition will naturally produce a certain degree of discomfort and annoyance, but _beyond this it is innocent_, save that it is made to cause much mental anxiety, mainly through ignorance, and has led thousands of victims to quacks, for treatment for conditions dishonestly represented and treated as both distressing and extreme. It is true that a large mass of enlarged veins may in time produce some atrophy of the testicle; it is likewise true, also, that virility or masculine potency may be to a trifling extent limited in this way. It is not true, however, that impotence can be so produced, because the affection is limited to but one organ, so that the impotency of which many men complain is mainly of psychical origin. Such individuals need explanations and advice as much as treatment, although it is difficult to elevate many of them from the condition of sexual hypochondria into which they gradually fall.

Resection of scrotum for varicocele. (Hartmann.)]

=Treatment.=--Treatment of varicocele may be _palliative_, _i. e._, it may consist of suspension of the overloaded testicle and somewhat relaxed scrotum within a well-fitting _suspensory bandage_, and this suffices for most mild cases in normally minded individuals. When, however, the condition preys deeply upon the mind or upon the body, or when it is actually and anatomically advanced, then _radical operation_ is legitimate and humane. Of the many operations recommended in time past only two will be described here, for it seems to me that all subcutaneous and blind methods are bad in theory as in practise.

_Excision of the varicose veins_ is easily performed under local cocaine anesthesia. It is done by incision below the external ring, over the course of the cord, the cord itself being exposed for two to three inches. Here the enlarged veins appear usually in a group (the pampiniform plexus), and as such can be isolated and separated from the balance of the cord, it being essential to _carefully exclude the vas_, as injury to or division of this canal would naturally be followed by impotence of that testicle. The veins involved being isolated to an extent of two inches, are ligated above and below, the intervening portion being then exsected, after which it is my custom to utilize the catgut with which this ligation is effected, threading it on each side into a needle, using each as a suture, thus providing two sutures, by which the divided ends are approximated and tied together, the effect being to bring the testicle up and make a more effective suspensory of the cord itself.

=Shortening of the Scrotum.=--To the above procedure, when the scrotum is much elongated and relaxed, may be added its _shortening by a species of amputation_. The entire procedure may be practised as follows: The scrotum being stretched downward is shortened by removing one and a half to three inches from the lower end of the scrotal pouch of skin and the contained connective tissue, including the septum. In this way the tunical sacs and lower ends of the testicle will be immediately exposed. The left testicle can now be drawn down, and the operation, described above, of exsection of a portion of its veins, may then be practised. This being completed the scrotal wound is closed with sutures, with or without catgut drainage. The effect is to not only remove the varicose veins, but to reduce the size of the scrotum, and to make it, as it were, a suspensory of living tissue (Figs. 675 and 676).

THE SEMINAL VESICLES.

The lower ends of the vasa and the seminal vesicles themselves suffer most commonly from the consequences of _tuberculous_ or of _gonorrheal infection_, travelling in either direction, they being easily invaded from the prostatic urethra along the seminal ducts. The consequence is _seminal vesiculitis_, which produces a more or less tender swelling, with discomfort referred to the lower end of the rectum, and discoverable by digital examination above the prostate. When the vesicles are distended or infiltrated they may be felt with the finger in the rectum. In addition there may be on pressure more or less discharge of fluid into the prostatic urethra, while the semen when emitted may be more or less mixed with blood.

It is necessary usually to differentiate between prostatitis or prostatic hypertrophy and vesiculitis.

Chronic involvement of the seminal vesicles may be best treated by a species of massage or “milking,” by which retained contents are coaxed along the ducts and into the urethra. Its local treatment is almost impossible. When the conditions resulting from infection of either type have become chronic and intractable we may take advantage of recent advances and decide upon _removal of the vesicles_ by operation. Fuller suggested that this be done by putting the patient in the knee-chest position or a modified Sims position. While it is not difficult to reach the vesicles through the rectum, the method has its disadvantages and the perineal route is much the better. The operation is then effected, much as is prostatectomy, by perineal opening and blunt dissection between the rectum and the prostate, carried upward until the vesicles themselves are reached, after which they may be curetted or extirpated by a process of enucleation.[74]

[74] In the treatment of infections of the seminal vesicles,
particularly those of gonorrheal origin, Belfield has advised
irrigation and drainage of the same through the vas deferens. He
brings this up against the skin of the scrotum, where it is easily
identified, and then, through a one to two-inch incision, made under
local anesthesia, exposes the vas, into which the blunted end of a
hypodermic-syringe needle may be introduced, by means of which a
solution of any desired agent may be injected. This being thrown in
the direction of the seminal current passes up through the vas and
into the vesicle. He has even recommended in certain cases to attach
the vas to the skin by a fine silkworm suture, and in this way to
make a minute fistula, which can be used for the purpose as long as
may be necessary. He considers the method invaluable in the treatment
of chronic gonorrheal vesiculitis or the chronic infections of the
seminal canal in the elderly, which are often mistaken for enlarged
prostate, as well as in cases of recurrent epididymitis resulting
from repeated invasion from behind. Thus he has seen benefit follow,
in tuberculosis of the epididymis, from irrigation with carbolic
solution. The amount injected into the vesicle should never exceed 2
Cc.

SPERMATORRHEA.

Accurately defined this term refers to the escape of semen under abnormal and involuntary conditions, an occurrence which is of great rarity. Most cases of so-called spermatorrhea are, in effect, but the escape of excessive or superfluous amounts of _prostatic mucus (prostatorrhea)_, the fluid, whether it appear drop by drop or in considerable quantity, being mistaken by the patient for semen. Thus with the extrusion of a hard fecal mass there may be sufficient pressure upon the prostate to express from it 1 Cc. or more of this fluid. True spermatorrhea, on the other hand, rarely occurs except in connection with disease of the vesicles or prostate, and will then be recognized rather by the detection of spermatozoa in the urine than from any phenomenon noticeable by the patient. All statements, therefore, made by patients to the effect that they suffer from involuntary escape of semen should be taken with the greatest allowance, and will usually be found to be misleading.

All of this might lead up to a considerable discussion of matters included within the domain of sexual physiology and hygiene, topics which, however, cannot be afforded space in the present work; all that can be said being that many patients are in need of accurate information who suffer acutely in mind, and sometimes slightly in body, for lack of it, and who are tempted by motives of delicacy to consult quacks and charlatans rather than their family physician.

CASTRATION.

The only operation of importance upon the external genitals not yet described is that of _castration_, _i. e._, removal of the testicle. This is ordinarily a simple procedure, requiring, first, incision of sufficient length. If the disease condition include the slightest infiltration or involvement of the overlying skin a little or the greater portion of it, as required, should be included in an oval incision, in order that it may be totally removed. The testicle and its coverings, being now exposed, are to be loosened from all their surroundings, the organ pulled down, and the cord brought into sight. If there be no reason for following up the spermatic cord it is sufficient to surround it with a ligature (chromic gut), at a convenient height above the testicle, after which the cord is divided below it and the mass removed. In most instances, however, the disease which calls for so much operating will require to be followed up along the cord, and perhaps through the inguinal canal down into the pelvis. This is done by continuing the incision in the proper direction, isolating the cord, ligating bleeding vessels, and finally dividing the cord itself at a point of election decided to be above the disease. Previous generations were hesitant about including the entire cord in a ligature, for fear of tetanus, but we now know that if the technique be carefully carried out there need be no fear on this score. The diseased mass being removed the wound is closed, with or without catgut drainage at one or more points, as may be indicated.
