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.
