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.
In a thin woman the vermiform appendix may sometimes be felt through the abdominal wall; and in cases of pain and inflammation in the right iliac region it is sometimes important to determine whether or not the trouble has started in the vermiform appendix or in the Fallopian tube. In order to palpate the vermiform appendix the examiner should stand upon the right side of the woman, who is lying upon her back, and should place the tips of the fingers of the right hand at about the junction of the upper and middle thirds of a line drawn from the middle of Poupart’s ligament to the umbilicus. By pressing backward firmly and gently, pulsations of the right common iliac artery may be felt; and then by drawing the hand directly outward it will pass over the different structures in this region lying between the palpating hand and the posterior abdominal wall. The appendix may often be felt, especially if it is indurated by inflammation.
_Percussion_ of the abdomen should be performed with the woman in the dorsal position; though, if the examiner suspects the presence of free fluid in the peritoneum, or ascites, much may be learned by percussing in different positions and noting the accompanying changes in the percussion-note.
