The survival time analysis of adult patients with nephrotic syndrome was done by Weibull distribution function and exponential-Weibull model. The results were, 1)the period from onset to death of the disease followed a Weibull distribution function with an increasing failure rate, 2)the expectation of survival time by exponential-Weibull model showed a sufficient adequancy of this model for use, 3)the risk analysis using exponential-Weibull model indicated that erythrocyte sedimentation, systolic blood pressure, blood uria nitrogen, red blood cells in urinary sediment and pathological classification of renal biopsy were the main risk factors to death.
