On opening his Body, we found about two or three Pints of a dark-coloured fœtid Water in the Abdomen; on cutting through, and squeezing the right Kidney, there came out a thin purulent Matter every where from its Substance, though it appeared sound; on raising and cutting through the Peritoneum, covering the left Kidney, there was a Discharge of about a Pint of black and very fœtid Water, which had every where surrounded this Kidney; and there were six mortified Spots on its Surface, as large as the End of one’s Finger, with a Depression in each about a Quarter or Half an Inch deep; most of the Substance of this Kidney seemed diseased, and it was full of Suppurations. The Bladder was contracted and thickened, and contained a rough Stone, which weighed three Ounces. The rest of the _viscera_ were sound. This Stone had certainly been in the Bladder long before the young Fellow received the Blow with the Cricket-Bat; but the Injury done the Kidney had probably aggravated the Symptoms. I do not remember ever to have seen convulsive Fits, such as this young Man had, in acute Diseases, except in one Case of a slow Fever, which came by taking Cold after a Salivation, and which I attended, along with Dr. _Pringle_. The Gentleman had three Fits exactly of the same kind as this young Man, at twenty-four Hours Distance from one another, and he died of the third. Those who really had the Disorder seemed to have received such an Injury of the Bladder, or Kidneys as required a considerable Space of Time to get the better of; and by reason of the short Time we had them under our Care at the flying Hospital, they seldom received much Benefit. One or two thought they grew better on taking the Bark and Balsam of _Peru_; at the same Time they bathed Morning and Evening the lower Part of the Abdomen and Perinæum, with Flannels dipped in gentle astringent Liquors, applied cold. Blisters applied to the _os sacrum_ had no Effect. OF A STOPPAGE of URINE. We formerly mentioned, that in acute Diseases many complained of a Stoppage or Difficulty of making Water; and others had this Complaint from Strictures of the Urethra, or Disorders of the Bladder or Kidneys[97]. [97] It is often very difficult to judge of the Cause, or to be able to determine exactly the Seat of these Disorders before Death; as the following Cases will shew.
