Cornell University Program of Computer Graphics The term computer graphics includes almost everything on computers that is not text or sound. Today almost every computer can do some graphics, and people have even come to expect to control their computer through icons and pictures rather than just by typing.
Anal fistula. An anal fistula is a small channel that can develop between the end of the bowel and the skin near the anus. An anal fistula can cause bleeding and discharge when passing stools-and can be painful. An anal fistula can occur after surgery to drain an anal abscess. In some cases, an anal fistula causes persistent drainage. In other cases, where the outside of the channel opening closes, the result may be recurrent anal abscesses. The only cure for an anal fistula is surgery.
Problem. A fistula is defined as a communication between 2 organ sites. Vesicovaginal fistula is a free communication between the urinary bladder and the vagina. The urine from the bladder freely flows into the vaginal vault, leading to total or continuous incontinence. Ureterovaginal fistula is a communication between the distal ureter and the vagina.
