The management of 15 recumbent patients with bone injury (not including paraplegic patients) who formed urinary calculi, observed during the year May 1, 1947 to May 1, 1948, was reported last year before the American Urological Society.1 Approximately 800 recumbent patients with bone injury were hospitalized at Walter Reed General Hospital in that period. The incidence of the low percentage (2 per cent) of calculus formation in such a large number of patients with similar injuries, hospitalized under almost identical management, makes it evident that there is a stone diathesis due to general derangement of calcium metabolism and/or local factors in the urinary tract.
The shortest period required for the formation of stone was 74 days, the longest 1,200 and the average 362. When we disregard the longest and shortest cases, the mean time was 272 days.
The following preventive regimen was carried out so far as possible:
