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.

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.

Overview

A bladder fistula (also called enterovesicular fistula) is an abnormal channel between the interior of the urinary bladder and other areas.

The channel (fistula) may form as a result of a birth (congenital) defect, damage done during surgery (surgical trauma), prolonged labor, or as a result of certain diseases that can occur in the genital/urinary (genitourinary) system. There are a number of different types of bladder fistulas. These fistulas may form a connection between the bladder and the vagina (vesicovaginal), the skin of the abdomen (vesicocutaneous), or the intestinal tract. Fistulas that connect to any part of the intestine are collectively referred to as vesicoenteric fistulas. Fistulas between the bladder and intestine can occur at the colon (colovesical, most common), rectum (rectovesical), ileum (ileovesical), or the appendix (appendicovesical). The result of any of these conditions is a free exchange of fluids between the bladder and the area connected by the fistula.

Incidence and Prevalence: Estimated incidence of vesicovaginal fistula after hysterectomy is from 1 to 10 women per 1,000 (Harris 1995; Gilmour 1999).

Approximately 50% to 70% of enterovesicular fistulas are caused by diverticulitis. Bowel cancer accounts for another 20%, and 10% are due to Crohn's disease ("Bladder Fistula").
