title: [Prostatic arterial embolization for benign prostatic hyperplasia in high-risk aged males].
abstract: OBJECTIVE
  To explore the efficacy and safety of prostatic arterial embolization (PAE) in the treatment of benign prostatic hyperplasia ( BPH) in high-risk aged males.
  
  
  METHODS
  We retrospectively analyzed the clinical data about 21 high-risk BPH patients aged 77-91 (mean 80) years treated by PAE.
  
  
  RESULTS
  PAE was successfully performed in all the 21 patients, with the operation time of 90-120 min. At 2 weeks, 3 months, 6 months, and 12 months after surgery, the International Prostate Symptom Scores (IPSS) were 18.3 ± 3.1, 9.8 ± 2.7, 9.4 ± 2.5, and 10.1 ± 2.2, the quality of life scores ( QOL) were 4.6 ± 1.4, 4.3 ± 1.2, 4.6 ± 1.1, and 4.9 ± 0.6, the maximum urinary flow rates ( Qmax) were (12.5 ± 2.5), (15.8 ± 2.4), (16.6 ± 2.2), and (16.3 ± 1.8) ml/s, and the postvoid residual urine volumes (PVR) were (35.0 ± 3.4), (13.0 ± 3.3), (10.0 ± 3.0), and (8.0 ± 2.5) ml, respectively, markedly improved as compared with the baseline (IPSS: 24.5 ± 3.7, QOL: 5.7 ± 1.6, Qmax: [8.3 ± 2.1] ml/s, and PVR: [98.0 ± 11.0] ml), with statistically significant differences in IPSS, QOL, Qmax, and PVR (all P < 0.05). The maximal velocity of blood flow in the prostate was obviously decreased and the prostate volumes were (74.4 ± 4.8), (42.5 ± 4.4), (38.3 ± 4.0), and (36.7 ± 3.5) cm3 at 2 weeks, 3 months, 6 months, and 12 months, respectively, also significantly reduced in comparison with (84.3 ± 5.4) cm3 preoperatively (all P < 0.05).
  
  
  CONCLUSIONS
  PAE is a safe and effective option for the treatment of BPH in high-risk aged males.
