My purpose in this paper is to call attention to, and illustrate by the report of cases, the effects of inadequate renal drainage and of phosphaturia in the formation of renal calculi in bedridden patients. In my experience it has been the phosphatic stones (calcium phosphate) which have produced the most serious results, because they can form rapidly and without symptoms, so that they may have already produced a serious condition when they are discovered.
The fact that renal calculi are frequently formed in patients having paralyses which produce disturbances of urination, such for example as fractures of the spine and poliomyelitis, has been so generally recognized and so frequently reported that it is unnecessary to devote any space here to confirming it. The discussions concerning preventive treatment have emphasized the correction of metabolic disturbances, the relief of urinary obstruction, the removal of foci of infection, regulation of the diet
