Abstract
PURPOSE
To compare the outcomes of prostatic artery embolization (PAE) in patients with different intravesical prostatic protrusion (IPP) grades.
MATERIALS AND METHODS
This retrospective single-center study included 128 patients (aged 50-86 years) who underwent PAE from 2013 to 2017. IPP grades were classified as follows: grade I (<10 mm), grade II (10-19 mm), and grade III (≥20 mm). Nineteen patients (14.8%) had grade I [mean IPP 7.8 mm, prostatic volume (PV) 64.1 cm3], 77 (60.2%) had grade II (mean IPP 14.9 mm, PV 87.0 cm3), and 32 (25%) had grade III (mean IPP 26.2 mm, PV 132.6 cm3), P < .01. The outcomes, including PV, international prostate symptom score (IPSS), and quality of life (QoL), were compared between the IPP grades at the 12-month follow-up. Clinical failure was defined as IPSS >7 or QoL >2.
RESULTS
IPP decreased (I: -8.2%, II: -27.3%, and III: -38.7%, P = .01), and all other endpoints improved (P < .01). Adjusted covariance analysis, considering baseline PV as a confounding factor, showed no correlation between the 12-month outcomes and baseline IPP. Clinical failure was observed in 17/128 patients (13.3%) and was similar in prevalence among the IPP groups (P = .20). Minor complications occurred in 43 patients (33.6%) and major in 3 (2.3%). There were statistical differences in the complications between IPP grades II and III (P < .01).
CONCLUSIONS
PAE was similarly effective in all the IPP grades at the 12-month follow-up, and there was no difference in the clinical failure between the groups. Complications in IPP grade III were more frequent than those in IPP grade II.
