RENAL AND URETERAL CALCULUS
Stone in the kidney may remain quiescent, producing no symptoms for years. A casual inspection of the urine which proves to contain pus, would suggest an inquiry into its source. Such may be the means of detecting a silent stone. Ordinarily, however, pain referred to the involved side is an almost constant symptom, varying from a dull a loin ache to the organizing pains present, when the calculus is lodged in or traversing the ureter.
