The flow was brilliant with blood. In both these cases I effected a cure by one application of solid nitrate of silver through the urethra to the prostatic sinus. The TREATMENT of vesical hæmaturia is the treatment of the cause, which, if possible, must be ascertained. For the symptom itself the internal use of iron, turpentine, opium, gallic and tannic acids, are of service. I have not derived any advantage from ergot. Locally, rest in bed, ice over the region of the bladder, and avoidance of straining at urination are generally all that is necessary. I have had good results from injecting the bladder with a solution of alum, gr. i-ij to ounce j of warm {136} water, and cures have been effected by injecting nitrate of silver in solution. It is not well to inject iron in solution, since this substance makes a hard clot, and a soft clot is preferable. When the bladder fills up with a solid clot of blood, the best treatment, according to my experience, is to administer opium freely and diluent drinks. The urine slowly dissolves the clot, which has already arrested the hemorrhage, in most cases by its pressure, and the blood flows away as a dark coffee-ground material, sometimes nearly black. If the catheter is used, the clot broken up or dissolved with pepsin or other substance, and washed or pumped out, a new clot is apt to form at once; and although this treatment is based on high authority, and is often practised successfully, it is a question whether the patient would not in many cases do as well, or better, by being let alone, soothed by opium, until the urine dissolves the clot and nature relieves him.
