This study investigated the frequency of an accessory pudendal artery in 15 adult cadavers fixed with formaldehyde solution. The prevalence of accessory pudendal artery varies between 7 and 75% according to the method of identification (imaging studies, microstereoscopic cadaveric dissection, and open and laparoscopic surgeries). Currently, under discussion is the role of this artery in postprostatectomy erectile dysfunction. Accordingly, it is important to know the true prevalence to appreciate its clinical significance. The internal pudendal system was examined through direct dissection, and findings were compared with the different methods of identification published.

We herein describe the superficial preprostatic vein (SPV) anatomy and determine its relationship with the accessory pudendal artery (APA). We reviewed 500 patients with localized prostate cancer who underwent conventional robot-assisted radical prostatectomy between April 2019 and March 2023 at our institution. SPV was defined as "any vein coming from the space between the puboprostatic ligaments and running within the retropubic adipose tissue anterior to the prostate toward the vesical venous plexus or pelvic side wall.

Background This study aimed, first, to angiographically investigate and analyze prostatic artery (PA) origin in a Greek male population with benign prostatic hyperplasia (BPH) treated with prostatic artery embolization (PAE) and, second, to correlate prostatic arterial anatomy with technical and clinical aspects of PAE. Methodology This was a retrospective study of BPH patients who underwent PAE in a single tertiary center in Greece from June 2019 to July 2022. For the first part of the study, PA was imaged with computed tomography angiography (CTA) before PAE and with digital subtraction angiography (DSA) during PAE in all patients.
