As heretofore explained, in the more severe cases the urethra is found in a very irritable condition. It is hyper-sensitive, especially in that portion just in front of the bladder, where the ejaculatory ducts open into it. We have also seen how this condition is one of the chief exciting causes of emissions. The remedies described for allaying this irritation are all excellent and indispensable; but there is another method of great value. This consists in the passage of a suitable instrument, a sound or bougie of proper size, two or three times a week. By the aid of this means, the abnormal irritation will often diminish with magical rapidity. The passage of the instrument of course needs to be done with great delicacy, so as to avoid increasing the irritation; hence it should not be attempted by a novice. Lack of skill in catheterism is doubtless the reason why some have seemed to produce injury rather than benefit by this method of treatment, they not recognizing the fact asserted by Prof. Gross in his treatise on surgery, that skillful catheterism is one of the most delicate operations in surgery. _Use of Electricity_.--The use of electricity in connection with that of the sound adds greatly to its utility. By means of the metallic instrument, also, electricity may be applied directly to the point of greatest irritation; and its soothing effect is sometimes really wonderful, as the following case will show:-- The patient, a man of unusual physical development, was suffering from nocturnal emissions and diminished sexual power, the result of early indiscretions and marital excesses. One of his most unpleasant symptoms was severe pain in the portion of the urethra near the openings of the ejaculatory ducts. After he had been suffering more than usual for a few days, we applied the faradaic electric current in the manner indicated above, for about fifteen minutes. At the end of that time the pain was entirely removed, though considerable suffering had been caused by the passage of the instrument, so sensitive was the congested membrane. The pain did not return again for two or three weeks, though treatment was necessarily suspended on account of absence. In another case, that of a young man, a student, at the beginning of treatment emissions occurred nightly, and sometimes as many as four in a single night, according to his statement, which we had no reason to doubt. Under the influence of these local applications, combined with other measures of treatment and a measurably correct regimen, the number of emissions was in a few weeks reduced to one in two or three weeks. Numerous other cases nearly as remarkable might be detailed if it were necessary to do so. In quite a considerable number of cases in which we have employed this plan of treatment, the results have been uniformly excellent. A very slight increase of irritation sometimes occurs at first, but this quickly subsides.
