In cases in which there is a sore or tender spot within the abdomen the contraction of the recti muscles may be altogether involuntary, persisting even when the patient is anesthetized. We see this in the rigid right rectus muscle of appendicitis. The hands should be warmed, and palpation should be performed with both hands. A certain amount of gentle stroking or massage of the abdomen will secure the patient’s confidence by making her feel that she will not be hurt by any sudden violent pressure, and will also prevent reflex contraction of the muscles. By proceeding in this way, slowly, the examiner can palpate the whole of the abdominal surface, exploring first the structures lying most anterior, and then, pressing the fingers more deeply, he can examine the more posterior structures. Fluctuation in an encysted fluid accumulation is generally readily determined. While one hand is placed against one side of the fluid mass and the opposite side is percussed by the fingers of the other hand, the wave of fluctuation is easily felt. Sometimes a thrill or a false wave of fluctuation is observed in the subcutaneous fat of obese women. This disturbing element may, however, be eliminated by an assistant pressing the ulnar edge of his hand in the median line upon the abdominal surface, thus stopping the fat wave of fluctuation. Special organs in the abdomen sometimes require special methods of examination. It is very often necessary for the gynecologist to examine the kidneys, because many women have movable or floating kidneys, and the nervous, gastric, and abdominal symptoms may be due to this condition. The presence of a floating kidney may often be determined by inspection; the presence of a movable kidney, however, must be determined by palpation. This should be performed with the woman in the sitting, or standing, erect posture; or sitting upon the edge of a chair, with the body inclined somewhat forward and the hands upon the knees; or lying upon a bed, on the side opposite the kidney that is being examined. One hand should be placed over the lumbar muscles; the other hand should be placed upon the anterior abdominal wall immediately below the costal margin, and should be pressed backward. If the kidney lies below its normal position, it may in this way be brought between the two hands, and can be felt to glide upward as the hands are pressed together. In case a movable kidney cannot readily be found, because it may have returned to its normal position, it may often be brought down again if the woman is made to cough.
