![d. Calculi of phosphate of lime are occasionally found in a diseased kidney, probably not proceeding from the urine, but from other secretions of the affected organ. In the col- lection belonging to Sir Benjamin Brodie, there are two kid- neys completely filled with calculi of this description. Calculi may form in the kidney, and exist unsuspected for an indefinite length of time; or they may produce hemor- rhage, or inflammation, or abscess, with or without obstruc- tion tp the flow of urine from the affected kidney ; with or without pain in the loins, pain in the ureters and bladder, fever, and extenuation. SECTION II. The Ureters. The ureters are liable to participate either in inflammation, or in tuberculous action originating in the kidney: they are liable to become enlarged from distension with urine, alone, or mixed with pus, in consequence of obstruction either from inflammatory stricture following irritation, or from calculi fill- ing and being stopped in their cavities. In general, calculi that cannot pass are arrested at the upper part of the canal [x. 70] ; but it has happened that a calculus has stuck in the vesical termination of the ureter, and has produced fatal disease of the kidney, when a fortunate movement of a sound in the bladder might have displaced it. The ure- ters will bear, or will grow to, a wonderful degree of di- latation, so as to attain a diameter of three-quarters of an inch, in consequence of stricture of the urethra. Sometimes when the ureter has been long distended with a calcu- lus, an abscess has formed in the loins, the ureter has ulcerated, and the calculus has passed by the opening. ix. 71.] The principal affections of the ureter are thus dependent upon the passage of calculi.
