Abstract

Objectives: To describe magnetic resonance imaging (MRI) characteristic of benign prostatic hyperplasia (BPH) in patients indicated for prostatic artery embolization (PAE) and to evaluate the correlation between MRI-based morphology and selected clinical as well as paraclinical finhdings. Methods: A retrospective–prospective study was conducted on 61 patients with BPH indicated for PAE between January 2024 and June 2025 at Tam Anh General Hospital. MRI freatures comprised total prostate volume (TPV), transition zone volume (TZV), transition zone index (TZI), intravesical prostatic protrusion (IPP), anterior fibromuscular stroma length (AFSM), prostatic urethral angle (PUA), and Wasserman classification. These figures were investigated the correlation with International Prostate Symptom Score (IPSS), quality of life (QoL), total prostate-specific antigen (PSA) and maximum urinary flow rate (Qmax) using Spearman correlation, ANOVA test and Kruskal–Wallis tests. Results: Mean values were as follows: TPV: 74,34 ± 28,63cm³;  TZV: 57,39 ± 27,59cm;, TZI: 0,75 ± 0,11 IPP: 9,74 ± 7,36mm; AFSM: 39,56 ± 7,80mm và PUA: 59,94 ± 10,44°.The majority of cases were Wasserman type 3 (67,2%) and type 1 (24,4%). TPV and TZV showed strong correlations with IPSS, QoL, and PSA (p < 0.05), while TZI, IPP, and AFSM demonstrated moderate correlations. PUA showed no significant correlation (p > 0.05). Qmax did not correlate with any MRI- based parameter. Mean IPSS and PSAtt differed significantly among Wasserman types 1, 2, and 3 (p < 0.05). Conclusions: In my cohort, the majority of patients were classified as Wasserman types 1 and 3. TPV and TZV measured on MRI demonstrated the strongest correlation with clinical and paraclinical. IPSS and QoL correlated more consistently with MRI - based findings compared with PSA and Qmax. Wasserman classification showed significant differences in mean IPSS and PSA across types. In addition, IPSS and QoL correlated more consistently with MRI - based findings compared with PSA and Qmax.
