No routine in the treatment of gleet will give satisfactory results beyond this fact, that patients should be instructed to regulate their lives by absolute rules as regards indulgence of every description, and avoidance of intestinal inactivity and constipation. The urine will be found concentrated and irritating in many of these cases, and this should be overcome by the free use of water and diluent drinks. Hyperacidity should be corrected by suitable alkaline medication, and remedies administered, already mentioned, which are supposed to medicate the urine. Capsules may be procured containing salol, oleoresin of cubebs, balsam of copaiba, and pepsin, and except in cases where there is already great irritation of the urinary tract, these serve their purpose admirably. When the anterior urethra alone seems to be involved, one of the milder injections already mentioned in describing the treatment of acute cases may be employed. When the deep urethra appears to be the site of continued irritation, it should then be treated extensively with deep irrigations and injections of suitable medicaments. The deep irrigations can be practised with or without the use of a catheter. The deep urethra may be flushed through a smaller catheter than the urethra will comfortably take, allowing the fluid to return through the urethral channel outside of the catheter itself. When this practice is adopted, hot water which has been made antiseptic should be used, preferably with one of the silver salts. The nitrate may be used in proportion of 1 to 500, and the citrate or lactate in strength of 1 to 300 or 1 to 400. Protargol is effective in 1 per cent. solution, or argyrol in 1 to 3 per cent. strength. In the employment of irrigation in these cases a shield should be used, by which the end of the penis may be covered and all danger of spattering avoided. The simplest expedient for this purpose is one-half of an old atomizer bulb, which may be punctured and slipped over the catheter or irrigator tube. Apart from mere irrigation it is well to deposit within the depths of the urethra, in the membranous portion, by means of a deep urethral syringe, a drop or two of a fresh solution of silver nitrate in distilled water, in strength of ¹⁄₂ to 1 per cent. This should be deposited behind the “cut-off” muscle, where it will cause a burning sensation for a short time. The strength of the solution is to be regulated by this complaint, as no benefit is derived from using it too strong. Of all the medication that has been suggested, nothing gives better results for this purpose than this silver nitrate. For ordinary urethral injections, besides those already mentioned, formalin may be used, but in weak solution (1 to 2000, or stronger if the patient can tolerate it); while picric acid has been recommended by Belfield and others in strength of 1 to 1000 or 1 to 2000.
