Moderate left hydroureteronephrosis with dilated ureter traced into the pelvis after the soft tissue mass in the cervical region. The cortical thickness of the left kidney is decreased suggesting long-standing hydronephrosis and secondary atrophy. The right kidney is normal in size, shape and excretory function. The urinary bladder is normal in distension and outline. A well-defined fat plane is demonstrated between the posterior wall of the bladder and the mass located near the vault of the vagina.
Colorectal cancer is the third most common cause of cancer death in the United States.
It appears to be associated with diets high in animal fat and protein and low in fiber. Seventy percent of colorectal cancers occur in the rectosigmoid region. Rectal cancers may present with bleeding, change in bowel habits, perineal pain, and symptoms of invasion of adjacent organs including hematuria, urinary frequency, or vaginal fistulas. Surgical removal is the only effective therapy. Anterior resection with anastomosis to the rectal stump is performed for upper rectal tumors and a combined abdominal and perineal resection with a permanent colostomy for distal rectal lesions.
