High post-void residual volume predicts worse durability after prostatic artery embolization
Baseline PVR ≥300 mL triples risk of PAE failure: composite endpoint (prostate surgery or indwelling catheter) 38.7% vs 11.3% (RR 3.43; 95% CI 1.76–6.70; p=0.0003) in this retrospective cohort. Early symptom scores improved similarly regardless of PVR, but durability suffers.
