Impact of High Baseline Post-Void Residual Volume on Outcomes Following Prostatic Artery Embolization.

This single-center retrospective study evaluated whether elevated baseline post-void residual (PVR) volume is associated with reduced prostatic artery embolization (PAE) durability. Of 573 PAE procedures performed from 2015 to 2023, 176 patients who fit the inclusion criteria were included in the analysis. They were stratified by baseline PVR ≥300 mL (n=25) versus <300 mL (n=151). The primary outcome was a composite of subsequent prostate surgery and/or need for indwelling urinary catheter. Secondary outcomes were changes in International Prostate Symptom Score (IPSS), Quality of Life (QoL) score, and PVR at 3-6 and 12 months. After inverse probability of treatment weighting, composite endpoint risk was higher in the PVR ≥300 mL group (38.7% versus 11.3%; RR 3.43; 95% CI 1.76-6.70; p=0.0003), while IPSS and QoL improvements were similar. Patients with baseline PVR ≥300 mL experienced comparable early symptomatic improvement after PAE but had a higher observed risk of later surgery or recurrent catheter placement.
