Urinary calculi after poliomyelitis are largely confined to long-term respirator patients. Prophylaxis of calculi can be effective if begun early in the paralyzing and immobilizing diseases. Proper positioning is required to prevent stasis of crystalline material in the genitourinary tract. Calcium intake of 500 to 700 mg. daily was achieved by limiting milk and milk products to the equivalent of one and one-half glasses. Having patients produce 1,500 to 2,000 ml, of urine daily is the hardest task in the prophylactic program. Placing fluid reservoirs, connected to self-service drinking tubes, next to each patient aided in attaining a high fluid intake. The medical problem of renal stones was discussed frequently in lay language with the patients as a group. Once the problem was understood by some of the patients, one or more usually prompted the rest to work toward the required fluid volumes. A program of prophylaxis of urinary calculi appears to be widely applicable.
