Abstract

The human urinary tract may contain crystals of a variety of compositions and habits. Although there is not a one to one correspondence between crystalluria and urolithiasis, the presence of crystalluria is proof that a state of supersaturation exists or existed somewhere in the urinary tract. In addition, crystalluria can reflect the state of the urine with respect to factors such as inhibitors of aggregation and growth which are important to urinary stone formation. Quantitation of changes in crystalluria can be used to evaluate the effectiveness of various forms of treatment. Using a previously described method for the evaluation of crystalluria1, we have studied 4835 voidings in 162 patients, both on and off treatment. A quantitative evaluation of crystalluria and supersaturation for calcium oxalate monohydrate and brushite in four groups of patients before and after treatment is presented.
