  • Methods of diagnosing complicated urolithiasis and predicting urolithiasis
    Patent number: 5366899
    Abstract: A method of diagnosing complicated urolithiasis consists in testing for and finding the presence of albumen in a urine sample. A portion of said sample is dried and a crystallographic study is performed. On finding a marginal amorphous area, accommodating a central crystalline area, pyelonephritis is diagnosed. On discovering a full crystalline area (i.e. with no marginal amorphous area), calculous pyelonephritis is diagnosed.The method of prognostication involves testing for and finding the absence of albumen in a urine sample. A portion of the urine sample is mixed with a 8-12% protein solution, the mixture is then dried and a crystallographic study is conducted. With a full non-transparent crystallization of the sample (i.e. without the marginal amorphous area), urolithiasis is prognosticated.
