Prostatic Branch of the Inferior Vesical Artery, Anterior View

Description

Anteriorly, the urinary bladder sits superior to the prostate, with the distal ureters entering the posterolateral bladder base while the urethra descends inferiorly through the prostatic urethra. A prostatic branch arising from the inferior vesical artery courses medially toward the bladder neck and then inferiorly into the glandular parenchyma of the prostate, where it arborizes into smaller arterioles. Periprostatic neurovascular strands flank the gland bilaterally, tracking along the lateral pelvic fascia near the posterolateral aspect of the prostate. Relationships are clear. Prostatic arterial anatomy matters because it sets the boundaries for safe dissection at the bladder neck and during control of prostatic pedicles in radical prostatectomy, where brisk bleeding can obscure the plane and raise the risk of capsular violation. Hypertrophied prostatic vascularity also becomes clinically relevant in benign prostatic hyperplasia and in prostatic artery embolization, where variant origins from the inferior vesical system and adjacent vesical branches can create non-target embolization risk to the bladder. An anterior orientation helps you teach how vesical and prostatic supplies interdigitate around the trigone and bladder outlet. Use this artwork in pelvic anatomy and urogenital blocks, in operative atlases covering transvesical and retropubic approaches, and in interventional radiology materials discussing prostatic artery embolization planning and complications.
