SYMPTOMATOLOGY.--Apart from the characteristic urine of the condition, there are no symptoms which can be regarded as in any way peculiar to the disease. The mode of onset is usually sudden, and yet many patients experience no symptoms whatever, and would be quite unaware that they were afflicted in any way, were they not aware of the fact that they are passing lactescent urine. Since the discharge is, however, a drain of very valuable nutrient and force-producing material, most patients sooner or later gradually grow weaker; and this symptom of weakness becomes sometimes very marked, so that they fall into a condition of extreme debility, even to fainting on exertion. Another symptom sufficiently frequent to deserve mention is pain in lumbar region, sometimes very severe, sometimes on one side, at others on both. Painful micturition, due to obstruction, is also a symptom traceable directly to the condition of the urine. The disposition of chylous urine to coagulate has already been alluded to. The coagulation taking place in the bladder, it is the clot which sometimes obstructs the urethra and makes urination difficult or impossible. Plugs of coagulum are ejected, sometimes with considerable force, after prolonged straining, and with this comes relief to the symptoms, which may be reproduced through the operation of the same cause. {120} Other symptoms which are occasionally present may have an accidental relation to the affection, while they may be due to it. Such are headache, nausea, and other gastric symptoms. Mention has been made, too, of the concurrence of superficial lymphatic leakage, especially on the lower part of the abdomen, the thighs, and the legs. Such leakage is often from little vesicular elevations which are evidently dilated lymphatic vessels. The presence of such leakage should suggest the examination of urine for lesser degrees of chyluria. In like manner, the urine should be examined in case of elephantiasis, lymph-scrotum, and chylous hydrocele, with which also chyluria is sometimes associated. The effect of intercurrent febrile states, whether symptomatic of local inflammation, as of the lungs, or whether the result of the idiopathic fevers, has often a singular effect on chyluria in causing its disappearance for a time. It would seem that states of high vascular tension, however induced, tend to make it cease. While chyluria has made its appearance, for the first time, in a number of cases during pregnancy, this condition in other instances has caused it to disappear, especially toward the later months; whence it would seem that the pressure of the rising womb has a favorable effect.
