[Effect of magnetic water on urinary calculi--an experimental and clinical study]

In recent years, many hospitals in China have employed magnetized water in the treatment of urolithiasis with quite satisfactory results. Since 1979, we have carried out the following basic researches: (1) We compared the effectiveness of several different types of apparatus producing magnetized water and found that the best type was the Shanghai JW-1 mode apparatus with 1,350 gauss and to-and-fro magnetizing for 12 times. (2) We had tested the solubility of oxalate, uric acid and phosphate urolith both in ordinary and in magnetized water and found that phosphate urolith had better solubility in the latter. (3) The physical and chemical characteristics of magnetized water were studied, and the calcium crystals were found to be also soluble in it. (4) Experiments on fishes living in magnetized water showed that in their kidneys the amount of calcium crystals and tissue calcium level were lower than those in ordinary water. The basic theory of treatment of urolithiasis with magnetized water is discussed.
