Randomised Clinical Trial of Prostatic Artery Embolisation Versus a Sham Procedure for Benign Prostatic Hyperplasia.

Background: Prostatic artery embolisation (PAE) has been associated with an improvement of lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH), but conclusive evidence of efficacy from randomised controlled clinical trials has been lacking.

Objective: To assess the safety and efficacy of PAE compared with a sham procedure in the treatment of LUTS/BPH.

Design, Setting, And Participants: A randomised, single-blind, sham-controlled superiority clinical trial was conducted in 80 males ≥45yr with severe LUTS/BPH refractory to medical treatment from 2014 to 2019 in a private clinic, with efficacy assessments at 6 and 12 mo after randomisation.

Peer-reviewed studies with > 5 patients and standard deviations and/or individual-level data on one or more of the following outcomes were included: prostate volume (PV), peak flow rate (Qmax), postvoid residual (PVR), International Prostate Symptom Score (IPSS), quality of life (QOL) score, International Index of Erectile Function (IIEF) score, and prostate-specific antigen (PSA) level.

Medium- and Long-Term Outcome of Prostate Artery Embolization for Patients with Benign Prostatic Hyperplasia: Results in 630 Patients.

Purpose: To confirm that prostatic artery embolization (PAE) has a positive medium- and long-term effect in symptomatic benign prostatic hyperplasia (BPH).

Materials And Methods: Between March 2009 and October 2014, 630 consecutive patients with BPH and moderate-to-severe lower urinary tract symptoms refractory to medical therapy for at least 6 months or who refused any medical therapy underwent PAE. Outcome parameters were evaluated at baseline; 1, 3, and 6 months; every 6 months between 1 and 3 years; and yearly thereafter up to 6.

Angiographic anatomy of the male pelvic arteries.

Objective: The purpose of this article is to review the CT angiographic and digital subtraction angiographic features of the male pelvic arteries.

Conclusion: An increasing number of vascular procedures are being performed in the male pelvis that require profound knowledge of the angiographic anatomy of the internal iliac artery (IIA). The major branches of the IIA in men can be used to classify the branching patterns.

Embolisation of prostatic arteries as treatment of moderate to severe lower urinary symptoms (LUTS) secondary to benign hyperplasia: results of short- and mid-term follow-up.

Objectives: To evaluate the short- and medium-term results of prostatic arterial embolisation (PAE) for benign prostatic hyperplasia (BPH).

Methods: This was a prospective non-randomised study including 255 patients diagnosed with BPH and moderate to severe lower urinary tract symptoms after failure of medical treatment for at least 6 months. The patients underwent PAE between March 2009 and April 2012.

Middle rectal artery: myth or reality? Retrospective study with CT angiography and digital subtraction angiography.

This work aimed to study the prevalence and radiologic anatomy of the middle rectal artery (MRA) using computed tomographic angiography (CTA) and digital subtraction angiography (DSA). The retrospective study (October 2010-February 2012) focused in 167 male patients with prostate enlargement (mean age 64.7 years, range 47-81 years) who underwent selective pelvic arterial embolization for the relief of lower urinary tract symptoms.

Prostatic arterial supply: anatomic and imaging findings relevant for selective arterial embolization.

Purpose: To describe the anatomy and imaging findings of the prostatic arteries (PAs) on multirow-detector pelvic computed tomographic (CT) angiography and digital subtraction angiography (DSA) before embolization for symptomatic benign prostatic hyperplasia (BPH).

Materials And Methods: In a retrospective study from May 2010 to June 2011, 75 men (150 pelvic sides) underwent pelvic CT angiography and selective pelvic DSA before PA embolization for BPH. Each pelvic side was evaluated regarding the number of independent PAs and their origin, trajectory, termination, and anastomoses with adjacent arteries.

Prostatic arterial embolization to treat benign prostatic hyperplasia.

Purpose: To evaluate whether prostatic arterial embolization (PAE) might be a feasible procedure to treat lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH).

Materials And Methods: Fifteen patients (age range, 62-82 years; mean age, 74.1 y) with symptomatic BPH after failure of medical treatment were selected for PAE with nonspherical 200-μm polyvinyl alcohol particles.

Prostatic arterial supply: demonstration by multirow detector angio CT and catheter angiography.

Objectives: To evaluate the prostatic arterial supply with multidetector Angio CT and Digital Subtraction Angiography (DSA).

Methods: DSA was performed in 21 male patients (7 of these also underwent Pelvic Angio CT); a further 4 patients only underwent Angio CT. Prostatic arteries were classified according to their origin, direction, number of pedicles, termination and anastomoses with surrounding arteries in 50 pelvic sides.

Polyvinyl alcohol particle size for uterine artery embolization: a prospective randomized study of initial use of 350-500 μm particles versus initial use of 500-700 μm particles.

Purpose: To evaluate whether different polyvinyl alcohol (PVA) particle sizes change the outcome of uterine artery embolization (UAE).

Materials And Methods: This randomized prospective study comprised 160 patients with symptomatic leiomyomas undergoing UAE with PVA particles from January to August 2008. In 80 patients in group A, UAE was started with 350-500 μm particles; in 80 patients in group B, UAE was started with 500-700 μm particles.

Design: Retrospective study.

Setting: Private hospital affiliated with a university.

Branching patterns of the male internal iliac artery: imaging findings.

The aim of this study was to establish the imaging findings of the main branching patterns of the male internal iliac arteries, using different imaging modalities (angio MR, angio CT and digital angiography). Twenty-one males (mean age 73.2 years) underwent imaging evaluation with angio MR, angio CT and digital angiography to define the internal iliac artery anatomy before selective embolization of the pelvic arteries.

The Role of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) in the Management of the Post-Embolization Symptoms after Uterine Artery Embolization.

Uterine artery embolization (UAE) is usually a very painful procedure. Although pain after the procedure can occur as a single symptom, it usually is associated with other symptoms such as nausea, vomiting, pelvic pain, general malaise, fever and leukocytosis that characterize the post-embolization syndrome. Management of the post-embolization symptoms and of pain in particular, is paramount if UAE is to be performed as an outpatient procedure.

Uterine artery embolization under electroacupuncture for uterine leiomyomas.

Purpose: To evaluate whether electroacupuncture is a safe and effective alternative to pharmacologic sedation/analgesia in uterine artery embolization (UAE) for leiomyomas.

Materials And Methods: A nonrandomized prospective study was undertaken in 70 consecutive patients (mean age, 39.5 years) undergoing UAE with polyvinyl alcohol (PVA) particles between August 2006 and January 2007.

Management of uterine artery embolization for fibroids as an outpatient procedure.

Purpose: To evaluate whether it is safe to perform uterine artery embolization (UAE) as an outpatient procedure.

Materials And Methods: This retrospective study was approved by the institutional review board and included 234 patients (age range, 24-58 years; mean age, 40.5 years) who underwent UAE as an outpatient procedure with polyvinyl alcohol particles between January 2007 and March 2008.

Materials And Methods: A randomized prospective study was performed in 80 patients (age range, 25-52 years; mean age, 41 years) undergoing UAE with PVA between March and August 2006. Forty patients received PVA particles mixed with ketoprofen, and 40 received bland PVA particles.

[Pulmonary embolism diagnosis].

Pulmonary Embolism is often considered a difficult diagnosis to establish. It is important to recognise clinical situations that leads to it. There are a few laboratory and imaging tests, that should be tailored to the available facilities in each institution.
