There are several arteries that supply blood to various regions of the human urinary bladder. Usually, two or three superior vesical arteries originate from the patent part of the umbilical artery as it runs anterolateral to the apex and the upper part of the body of the bladder. The inferior part of the bladder, including the vesical neck, is supplied by the inferior vesical artery. The inferior vesical artery arises from the internal iliac artery and runs through the connective tissue close to the floor of the pelvis before distributing to the bladder. In the male, the base of the bladder is supplied by the artery of the ductus deferens. In the female, the base is supplied by the inferior vesical and vaginal arteries.
Introduction of prostate artery embolization (PAE) in Sweden
Published in Scandinavian Journal of Urology, 2019
The median age was 73 (56–90) years. Before treatment, 14 (38%) patients were urinary catheter-dependent, and five (13%) performed CIC (Table 1). Median pre-operative prostate volume was 92 (40–300) cc, median pre-operative urinary flow was 7 (1–14) ml/s and median residual volume was 200 (12–2100) ml. In 17 patients without pre-operative urinary catheter, median IPSS was 21.2 (8–34) and QoL was 4.6 (3–6). Bilateral PAE was achieved in 32 patients (84%). In one patient (3%), the inferior vesical artery was impossible to intubate bilaterally, due to tortuous, calcified and narrow vessels and four patients (11%) received unilateral embolization for the same reason. All patients had a follow-up at 3 months and 16 patients had a follow-up at 12 months. The mean follow-up time in the cohort was 6.9 months. Of the 14 urinary catheter-dependent patients at baseline, only three patients were catheter users at follow-up. Of five patients with CIC at baseline only one patient used this treatment at follow-up (Table 2). Median urinary flow improved from 7 (1–14) to 13 (6–40) ml/s, and median residual urine improved from 200 (12–2100) to 100 (0–300) ml at follow-up. Significant median IPSS and QoL improvements were reported (Table 3). According to the composite outcome variable clinically successful treatment was achieved in 31 (84%) cases. The improvement was stable in all patients but one, who experienced LUTS recurrence after 8 months. Five patients did not improve (Table 4), and one patient declined follow-up. No major PAE treatment-related complication was noted, but two (5%) minor complications occurred (Table 5). No patients were treated by alpha-blocker or 5α-reductase inhibitors after the PAE.
