In some few instances there is complete inability to pass water until the patient lies down and replaces the uterus with her finger; in other cases micturition may be annoyingly frequent. Constipation is often complained of, and, if the woman be careless, a large accumulation of feces may take place in the rectum. By a vaginal examination the os uteri is found low down, and if the cervix is of the natural length, we know that it is prolapsis. If a round tumor is seen projecting beyond the vulva, and if at the lowest part of it there is what seems to be the mouth of the uterine cavity, it may be advisable to introduce a sound or catheter, to make sure that the opening is not a mere cleft in a uterine polypus. (Of course, you would not use a sound if you suspected pregnancy.) If there are ulcers, cracks, etc., they may be detected, the ulcers looking as if portions of the mucous lining had been punched out. In pregnancy, displacements may occur either slowly or suddenly, though the woman may have had nothing of the kind previously, or they may be the continuation of a previous prolapse. The progressive development of the uterus generally removes the prolapsis about the fourth or fifth month, but if the pelvis is very large, it may possibly continue. As in other cases of prolapsis, the pregnant woman may suffer very much from it. She may suffer from a feeling of weight at the anus; painful tractions in the groins, lumber regions and umbilicus; a fetid discharge may come on; there may be complete retention of urine, very obstinate constipation, etc.; and the pressure on the uterus may cause abortion. For complete retention of the urine the catheter may be used, or the womb may be pressed up by one or two fingers introduced into the vagina; or the woman may be able to urinate if she lies down and elevates her hips considerably.
