External urethrotomy is essentially a median perineal section, carried down at least to the urethra. It is done preferably with a guide, usually a fine bougie. With it the urethral channel may be easily identified; without a guide, in aggravated cases, it is often a difficult matter to identify and dissect out the urethra, and then to find its tortuous passage-way and follow it into the bladder. Patience and a knowledge of the anatomy of the perineum will lead to success. Sometimes extensive dissections are necessary, and the perineal wound needs to be widely retracted in order to better expose the deep tissue. Once the urethra is identified it may be followed in each direction, and the case should not be left until the entire canal has been restored to its normal caliber. In these cases it is best to leave a self-retaining catheter in the perineal wound for at least a day, after which it is sometimes of benefit to introduce a catheter through the meatus, and leave it in the urethra for two or three days. Such a urethra is an infected channel, and must be so cared for that no retention or infection of fresh wounds occurs.
PERINEAL ABSCESS.
Perineal abscess is the not infrequent consequence of a very tight and deep stricture, having its beginnings as a folliculitis, with subsequent extension and perforation, with escape of urine, and sometimes with the formation of acute, diffuse phlegmon, which may even extend into the scrotum or to the abdominal wall. Ordinarily it constitutes a circumscribed collection of pus. Such a phlegmon when neglected may be followed by extensive burrowing of pus, or local sloughing, with gangrene, and partial or complete destruction of the external genitals. When such a phlegmon occurs above the triangular ligament there will be swelling about the prostate, with edema of the anterior rectal wall, while the prostate itself may become later involved. Such a collection may terminate as an ischiorectal abscess, associated with perineal fistulas.
The inevitable results of such conditions have two or three disastrous tendencies, such as burrowing of pus and the formation of urinary fistulas, sometimes at considerable distance from the urinary channels. The same is true in traumatic cases, for in such cases there may be the expression of an old and neglected stricture. To the chronic condition may be added that of tuberculous infection.
Treatment.
—The treatment of such abscesses and fistulas is based upon the principles of evacuation of pus and restoration of the urinary canal to its proper size. This may be an easy or a difficult task, but it should be accomplished by whatever method will permit it with the least damage to tissues. When urinary infiltration threatens gangrene extensive incisions should be made. When the scrotum is swollen, as it may be to enormous dimensions, free opening should be made into it to permit escape of serum and pus if present. Even the surrounding tissues, including the penis, may be enormously edematous. This swelling will rapidly subside when pressure upon the deep veins has been relieved, but pus, no matter where present, must be evacuated.
URINARY FEVER.
Instrumentation of any kind within the urethra may, in some individuals, be followed by what has been called urethral or urinary fever, including chill, pyrexia, with sometimes the development of an acute inflammatory affection, either of the urethra or even of the kidney, with not only retention but actual suppression of urine. These manifestations are ordinarily regarded as due to toxemia, but are sometimes difficult to explain, because their violence seems so disproportionate to the amount of intervention. Thus I have known an individual to die, of apparently acute uremia, within four days after the painless passage of a sound for dilatation of an old stricture, the same not being followed by any blood or local disturbance.
These accidents were more prone to occur before the introduction of antiseptic methods in all urethral instrumentation. At present they are much rarer than in former days. Nevertheless the passage of any instrument, even for legitimate examination, as for stone, may be followed by unpleasant consequences. These are preventable to some degree as well as curable, by antiseptic local measures, as well as by the administration of quinine or urotropin, especially the latter, with sitz baths and perhaps general antifebrile measures, while any local disturbance thus set up is to be treated on general principles.
