A Manual of the Operations of Surgery / For the Use of Senior Students, House Surgeons, and Junior Practitioners

The shoulder of the staff can now be passed through the stricture if the operation is complete; if not, the incision must be extended, always in the middle line, and guided by the groove. When thoroughly divided, the staff is now to be withdrawn, and a full-sized catheter with a double curve passed into the bladder. This should not be furnished with a stop-cock or plug, lest the bladder should by inadvertence be allowed to be too full, and extravasation into the cellular tissue of the urethra take place along the side of the instrument.

The catheter should be tied in, and left for two, sometimes for three days, when it can generally be removed with safety, and a bougie should be passed at intervals of three or four, till the wound is healed. To prevent recurrence of the stricture, it is a wise precaution to pass an instrument at intervals for many months after the cure is apparently complete.

In certain cases, where the stricture is far back and the urinary symptoms severe, Mr. Syme found advantage from the introduction of a shorter double-curved catheter (only about nine inches long) through the wound into the bladder, where it should be left for three days. This seems to diminish the risk of rigors, and other symptoms of fever, which are apt to occur when the urine is allowed for the first time to pass over the wound.

Perineal Section is an operation both dangerous and difficult; as Sir Astley Cooper used to say, "the surgeon who performs it requires to have a long summer's day before him."

No director or guide can be passed. A full-sized catheter must be passed as far as possible up to the stricture, and held firmly in the middle line. The patient must be tied up in lithotomy position on a table in the very best light that can be obtained. The perineum being shaved, an incision must be made in the middle line from over the point of the catheter to the verge of the anus, if the stricture extends far back.

The urethra should then be opened over the catheter, the edges of the mucous membrane held to each side by silk threads passed through them; and the surgeon must endeavour to pass a fine probe into the opening of the stricture; if this can be done, it is comparatively easy to slit the stricture up. If not, the surgeon must simply seek for the remains of the urethra by slow, cautious dissection in the middle line. If successful, a catheter must be secured in the bladder in the usual way.

A stricture near the orifice, or, as it is not uncommon, involving merely the meatus, can be treated with great ease in the above manner by division on a grooved probe. When quite close to the orifice, with a well-defined hardness, as of a ring round the urethra, it may be divided subcutaneously by a tenotomy knife or other narrow-bladed instrument. It is not necessary to keep a catheter in the bladder in cases where the stricture has been in front of the scrotum.

Puncture of the Bladder.—A patient and dexterous use of the catheter prevents this operation from being often required; still, circumstances may arise in which it is found impossible to enter the bladder per vias naturales. In such a case the bladder may be punctured from the outside by a curved trocar and canula, in either of two situations.

1. From above the pubis.—This operation is a very simple one, and when the bladder is distended need not imply a wound of the peritoneum.

Operation.—A preliminary incision, varying in length according to the amount of fat, should be made above the pubis exactly in the middle line; the edges of the recti should be separated, the peritoneum pushed out of the way and upwards by the finger, and a curved trocar plunged into the distended bladder obliquely backwards. The canula should be retained for a day or two, and then a flexible catheter with a shield inserted instead. Such instruments have been worn for years. The aspirateur pneumatique of Dr. Dieulafoy will be found an exceedingly useful instrument for puncture of bladder and removal of urine. The author has now used it very frequently with the best results. Its advantage is that the urine is removed through an aperture so small as to allow of the withdrawal and reintroduction of the canula as often as is necessary.
