The normal day output (8:00 a. m. to 8:00 p. m ) is 23 times the normal night output.This ratio is changed in renal disease, in some cases of heart failure, and in hyperaldosteronism .,Proteinuria: The presence of protein in the urine indicates increased glomerular permeability and some degree of diminution of tubular reabsorption of protein. It appears in many types of renal disease. Slight proteinuria is seen in congestive heart failure, infectious diseases, and after a heavy meal，and in some cases is associated with prolonged standing (orthostatic(直立的) proteinuria) or with vigorous exercise.,Lesson Four Urinalysis in Testing Renal Function,Casts: Casts result from precipitation of protein in the tubules. Waxy and fatty casts are suggestive of nephrosis. Pus cells: These are seen in large numbers in any genitourinary infections. (Women should cleanse the vulva, spread the labia, and collect a “clean” specimen free of vaginal leukocyte.),Lesson Four Urinalysis in Testing Renal Function,Hematuria: Gross or microscopic hematuria may result from glomerulonephritis, infection, trauma (including calculi), strictures, drug poisoning, or tumors of the kidneys, bladder, or urethra .,Lesson Four Urinalysis in Testing Renal Function,Hemoglobinuria: Hemoglobinuria found in urine following hemolysis associated with paroxysmal nocturnal hemoglobinuria, sickle cell crises, idiosyncrasy to cold, acute severe hemolytic reaction, or transfusion reaction .,Lesson Four Urinalysis in Testing Renal Function,Bacteria: Bacteria in the urine may be specific for infection, as in renal tuberculosis, pyelonephritis , cystitis.,Lesson Four Urinalysis in Testing Renal Function,Collection and preservation of urine for analytical testing must follow a carefully prescribed procedure to insure valid results. Laboratory testing of urine generally falls under three categories, i. e. chemical, bacteriologic, and microscopic examination. There are three kinds of collection for urine specimens: (1) random; (2) timed , and (3) 24-hour total volume.,Collection of Urine for Screening Purpose,Random specimens are collected at any time. Test results for a random collection are expressed per unit volume if the result is a quantitative analysis. Much reporting of testing on a random collection is expressed as “positive” or “negative”, indicating the presence or absence of a particular constituent, such as glucose. A randomly collected urine specimen is often more convenient for the patient and will be suitable for most screening purpose.,Collection of Urine for Screening Purpose,Probably the best specimen for routine examination is the first morning voiding, fresh, concentrated, with an acid PH. If the urine is dilute, small but pathologic increases in content of protein, sugar, red blood cells, white cells, and casts may be missed. Alkalinity and hypoosmolality hasten dissolution of casts and red cells. If specimens cannot be examined immediately, those with specific gravity less than 1.010 should probably be recollected if possible, especially if they are alkaline.,Collection of Urine for Screening Purpose,First morning specimens also tend to be more uniform, are more likely to reveal impairment of kidney concentrating ability, and to contain pus and mucus in the presence of infection. They are, however, less likely to contain sugar and protein. Most specimens obtained in the practitioners office are collected from ambulatory patients who have eaten 2 to 3 hours previously. These specimens are more likely to contain protein or reducing substances.,Collection of Urine for Screening Purpose,For chemical and microscopic examination, a voided specimen is usually suitable. If the specimen is likely to be contaminated by vaginal discharge or hemorrhage, a cleanvoided specimen is collected. It may be necessary to pack the vagina or use a tampon in some cases, especially when examination of the urinary sediment is critical.,Collection of Urine for Screening Purpose,Do not skip lightly over the rather tedious details of proper urine collection and preservation. Neglect of this aspect of the examination frequently renders all subsequent information uninterpretable or useless.,Collection of Urine for Screening Purpose,名称 通用名 前（后）缀 示例 胆 gallbladder chole- cholecystectomy 胆囊切除术 肠 intestine entero- enteritis 肠炎 脾 spleen spleno- splenectomy 脾切除术 肾 kidney nephro- nephritis 肾炎 膀胱/囊 bladder cysto- cystoscopy 膀胱镜 肾上腺 adrenal adreno- adrenocortical 肾上腺皮质的 支气管 bronchus bronch-/ bronchia 支气管 broncho- bronchoscopy 纤支镜,与人体
