摘要：

Prostatic artery embolisation (PAE) and transurethral resection of the prostate (TURP) are two of the surgical options for treatment of lower urinary tract symptoms/benign prostatic obstruction (LUTS/BPO). Our aim was to compare the efficacy and safety of PAE and TURP for LUTS/BPO treatment at long-term follow-up. We conducted a randomised, open-label, single-centre trial at a Swiss tertiary care centre. The main outcome was the change in International Prostate Symptom Score (IPSS) after PAE versus TURP. Secondary outcomes included patient-reported outcomes, functional measures, and adverse events assessed at baseline and at 3, 6, 12, 24, and 60 mo. Between-group differences in the change from baseline to 5 yr were tested using two-sided Mann-Whitney and t tests. Of the 103 patients with refractory LUTS/BPO who were randomised between 2014 and 2017, 18/48 who underwent PAE and 38/51 who underwent TURP reached the 60-mo follow-up visit. The mean reduction in IPSS from baseline to 5 yr was -7.78 points after PAE and -11.57 points after TURP (difference 3.79 points, 95% confidence interval [CI] -0.66 to 8.24; p = 0.092). TURP was superior for most patient-reported secondary outcomes except for erectile function. At 5 yr, PAE was less effective than TURP regarding objective parameters, such as the improvement in maximum urinary flow rate (3.59 vs 9.30 ml/s, difference -5.71, 95% CI -10.72 to -0.70; p = 0. 027) and reduction in postvoid residual volume (27.81 vs 219.97 ml; difference 192.15, 95% CI 83.79-300.51; p = 0.001). The improvement in LUTS/BPO at 5 yr after PAE was inferior to that achieved with TURP. The limitations of PAE should be considered during patient selection and counselling. In this study, we show the long-term results of prostate artery embolisation (PAE) in comparison to transurethral resection of the prostate (TURP) for the treatment of benign prostate enlargement causing urinary symptoms. PAE shows good long-term results in properly selected patients, although the improvements are less pronounced than with TURP. This trial is registered on ClinicalTrials.gov as NCT02054013.
