Introduction: For the implementation of suitable radiation safety measures in [Lu]Lu-PSMA-617 therapy, additional insight into excretion kinetics is important. This study evaluates this kinetics in prostate cancer patients via direct urine measurements.
Methods: Both the short-term (up to 24 h, n = 28 cycles) and long-term kinetics (up to 7 weeks, n = 35 samples) were evaluated by collection of urine samples.
