Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Factors Influencing Duration

Duration due to hematuria caused by trauma or exercise depends on whether the job requirements are physically strenuous. For hematuria due to a urinary tract infection, length of disability may depend on the availability of convenient restroom facilities and the ability to take frequent breaks.

Medical Codes

ICD-9-CM:
599.70 - Hematuria, unspecified
599.71 - Gross hematuria
599.72 - Microscopic hematuria

Diagnosis

History: Concomitant symptoms vary according to the underlying cause of the hematuria. The individual may report seeing blood in the urine or experiencing pain on urination; however, the bleeding is usually painless. A fever, rash, or lower abdominal pain may also be present. Frequent urination may later change to urinary retention. Recent trauma to the abdomen, back, or flank may be reported.

Physical exam: The blood may be clearly visible as the urine comes out red; small amounts of blood may give the urine a cloudy or smoky appearance; or blood may not be visible at all except under a microscope. Fever, rash, or elevated blood pressure (hypertension) may be present. A mass in the abdomen or pelvic region may be apparent upon applying pressure to the abdominal area (palpation).

Tests: Diagnostic tests include a urinalysis and urine culture. Urine samples should be carefully collected in sequential portions (known as aliquots) to help isolate the potential source of bleeding. For example, hematuria in the first voided aliquot indicates that the bleeding may originate from the urethra and/or the prostate. In addition to red blood cells, a urinalysis may reveal white blood cells indicative of a urinary tract infection. An analysis of chemical components may reveal the presence of variable amounts of protein (proteinuria), which may be a sign of poor kidney function. Groups of cells and debris molded together in the shape of the kidneys' tiny filtering tubes (casts) can signal kidney disease. High levels of wastes filtered out from the blood and usually excreted by the kidneys through the urine may be detected by analyzing a blood specimen and is additional evidence of kidney disease.

The presence of cysts, stones, or tumors can be detected through images of the urinary tract using ultrasound or computed tomography (CT) scan. Intravenous pyelography (IVP) follows the route of a dye through the urinary tract using x-ray imaging and gives important information about the kidneys, ureters, and bladder. Angiography is a procedure that enables the vessels in the kidneys to be seen on film after they have been filled with a substance that shows up on x-ray (contrast medium); angiography can also be done with CT (CT angiography [CTA]) or magnetic resonance imaging (MRI) (magnetic resonance angiography [MRA]). Direct examination of the bladder and ureters may be achieved using a fiber-optic instrument inserted through the urethra (cystoscopy and ureteroscopy).
