Adjusted* failure-free probability, according to treatment type
* Adjusted for age, gender, comorbidity, benefit plan type, employment classification, employment status, region of residence, patient MSA, provider MSA, and treatment year.
Overall, the adjusted failure-free probabilities were high for all three treatments. Endopyelotomy had the lowest failure-free rates (logrank p<0.0001). For all three treatments, the majority of failures occurred within the first two years.
