The increases in urinary tubular markers were not significantly associated with hemolysis or the number of PFA applications (Δα1MG vs ΔFree Hb: ρ = 0.033, p = 0.56; ΔNAG vs ΔFree Hb: ρ = 0.046, p = 0.41; pentaspline catheter count vs Δα1MG: ρ = 0.041, p = 0.61; pentaspline catheter count vs ΔNAG: ρ = –0.0606, p = 0.453; circular multielectrode array catheter count vs Δα1MG: ρ = 0.149, p = 0.0525 — showing a weak trend without statistical significance; circular multielectrode array catheter count vs ΔNAG: ρ = –0.0026, p = 0.973).
