{Abstract}: <B>UNASSIGNED: </B>Transrectal ultrasonography (TRUS) is the best route for examining the prostate gland because of transducer proximity, elaboration of zonal anatomical details, and Doppler assessment of prostatic arteries' hemodynamics.<BR><B>UNASSIGNED: </B>This was a cross-sectional study of 300 men with benign prostatic enlargement (BPE) and 300 healthy age-matched controls. The resistive index (RI) of the left capsular, right capsular and urethral arteries were assessed by TRUS and correlated with these parameters: maximum urine flow rate (Q max), total prostatic volume (TPV), transitional zone volume (TZV), transitional zone index (TZI), presumed circle area ratio, and the International Prostatic Symptoms Score (IPSS).<BR><B>UNASSIGNED: </B>The RI of capsular and urethral arteries correlated significantly with Q max, TPV, TZV, TZI, and IPSS. Of the three different RIs evaluated, the RI of UA showed the strongest correlation with Q max (r =- 0.51; P < 0.0001). The RIs were significantly higher in obstructive BOO than the non-obstructive group (Q max of <15 ml/sec and ≥15 ml/sec, respectively). The mean RI values were 0.73 ± 0.05 vs. 0.63 ± 0.04 for the RCA; 0.73 ± 0.05 vs. 0.62 ± 0.04 for the LCA; and 0.73 ± 0.06 vs. 0.62 ± 0.05 for the UA in the BPE and controls, respectively (P < 0.001). The TPV values were 52.36 ± 28.67 and 18.28 ± 4.26 in BPE and controls, respectively (P < 0.001).<BR><B>UNASSIGNED: </B>Prostatic artery RIs are elevated in BPE. Increase in RI correlated with increase in TPV, TZV and TZI, urinary symptoms' severity, poor QOL, and the severity of BOO.
