Prostatic artery embolization may do away with catheterization need in AUR patients: Study
China: Prostatic artery embolization (PAE) can be used for achieving freedom from catheterization in patients with acute urinary retention (AUR) caused by benign prostatic hyperplasia (BPH), reveals a recent study.
The study findings, published in the Journal of Vascular and Interventional Radiology, suggest that Prostatic artery embolization (PAE) may offer an alternative to traditional cytoscopic techniques.
Hai-Bin Shi, the First Affiliated Hospital of Nanjing Medical University, Nanjing, Jiangsu, China, and colleagues aimed to determine the ability of prostatic artery embolization to achieve freedom from catheterization in patients with acute urinary retention caused by benign prostatic hyperplasia.
For this purpose, the researchers performed a retrospective single-center study between June 2014 and March 2019 in patients with lower urinary tract symptoms (LUTS) caused by BPH. PAE was performed in 154 eligible patients, of which 76 suffered from spontaneous AUR and had indwelling catheters placed and kept until the procedure, owing to clinical failure in the removal of the previous intermittent catheter. The patients were followed for at least 12 months.
The first trial without catheter was performed 3 days after PAE. Successful catheter removal within the first 30 days after PAE was considered a clinical success. The rate of patients free from catheterization, LUTS relief, prostate volume, and adverse events was recorded.
Key findings of the study include:
· Clinical success was achieved in 92.1% patients.
· The rates of freedom from catheterization were 90.3%, 83.3%, and 80.6% at 3-, 6-, and 12-months follow-up, respectively.
· The median elapsed time from PAE to catheter removal was 10 days. However, 18 patients needed further interventions.
· Symptom scores revealed a continuous improvement in urinary symptoms.
· The mean prostate volume showed a statistically significant decrease at 3 and 12 months compared with its baseline value. No severe adverse events occurred.
Our findings show that Prostatic artery embolization (PAE) can achieve freedom from catheterization in patients with acute urinary retention (AUR) caused by BPH, concluded the authors.
