The activity of the bleeding may be acute, sub- acute, and chronic in development, scanty, moder- ate, or copious in amount, intermittent or remittent, and recurrent or persistent in course. The causes fall into the commonplace classifica- tion of traumatism, genital disease, urinary disease, systemic infection, and parasites, particularly ento- zoa. This classification of the causes may be sim- ple, but the designation of a definite etiology is often fraught with the utmost difficulty and uncer- tainty. The local origin of hematuria may be at any his- tological point of the anatomical subdivisions of the urogenital tract, hence may be renal, ureteral, vesical, prostatic, or urethral. Here again the rec- ognition of the precise bleeding point or tissue may sometimes defy our best efforts. This paper intrinsically deals with blood in the urine from the standpoint of the general practi- tioner and will state, it is hoped, a few of the broad facts concerning this symptom. The clinical diagnosis of hematuria includes, not only an exhaustion of all the time honored older means of recognition, but also a judicious applica- tion of cystoscopy, ureteral catheterization, ure- thrascopy, radiography, and any other means sug- gested by a given case. The laboratory diagnosis of hematuresis is an essential detail of this impor- tant topic, but space forbids more than mention of the fact that minute amounts of blood are detected only with the microscope or with such procedures as the guaiacum test (Almen’s), liquor potassae test (Heller’s), and the spectroscope, as examples. Let us, therefore, rather consider laboratory investiga- tion as slightly beyond the limits of this paper. The clinical diagnosis of hematuria must embrace determination of the cause and the focal point of the bleeding, so far as practicable. The broader causes of urogenital hemorrhage are slightly the a
