Frank
Frank is 52 years old and has been diagnosed with ADPKD by a kidney ultrasound. Frank is at risk for rapid disease progression, as indicated by the following risk factors: being male, rapid historical eGFR decline*, hypertension before age 35, urologic events before age 35, proteinuria/albuminuria, family history of ESKD by age 58, and TKV greater than expected for age. Let's take a closer look with some prognostic tools to confirm the risk of rapid disease progression and assess how rapidly his disease may progress.1,2
