PurposeThe aim of this study was to investigate whether prostatic artery embolization (PAE) can be considered a long-term cost-effective treatment option in patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia in comparison to transurethral resection of the prostate (TURP).MethodsThe in-hospital costs of PAE and TURP in the United States were obtained from a recent cost analysis. Clinical outcomes including nature and rate of adverse events for TURP and PAE along with rates of retreatment because of complications or clinical failure were obtained from peer-reviewed literature. A decision tree–based Markov model was created, analyzing long-term cost-effectiveness for TURP and PAE from a US health care sector perspective. Cost-effectiveness over a time frame of 5 years was estimated while assuming a willingness to pay of $50,000 per quality-adjusted life-year (QALY). The primary outcome was incremental cost-effectiveness ratio.ResultsPAE resulted in overall cost of $6,464.92 and an expected outcome of 4.566 QALYs. In comparison, TURP cost $9,221.09 and resulted in expected outcome of 4.577 QALYs per treatment. The incremental cost-effectiveness ratio for TURP was $247,732.65 per QALY. On the basis of the willingness-to-pay threshold, PAE is cost effective compared with TURP.ConclusionsOn the basis of our model, PAE in comparison with TURP can be regarded as a cost-effective treatment option for patients with lower urinary tract symptoms within the US health care system. 相似文献

PurposeThis study compared the safety and efficacy of prostatic arterial embolization (PAE) with that of trisacryl gelatin microspheres of different sizes for treatment of benign prostatic hyperplasia (BPH).Materials and MethodsThis study consisted of a single-center, randomized controlled clinical trial in 138 patients who underwent PAE for BPH between July 2015 and December 2016. Patients were randomized to PAE using microspheres of different sizes: group A patients were treated with microspheres 100–300 μm, group B with 300–500 μm, and group C with 100–300 μm followed by 300–500 μm. All patients were evaluated before and at 1, 3, 6, 12, and 18 months after PAE. Baseline data were comparable across the 3 groups, using the following mean International Prostate Symptom Score/quality of life (IPSS/QoL); prostate volume (PV) scores, respectively: 23.0/4.14; 87.9 cm3 (group A); 23.0/4.09; 89.0 cm3 (group B); and 24.2/4.29; 81.0 cm3 (group C) (P > 0.05).ResultsMean IPSS/QoL scores; PV after PAE were: 9.98/2.49; 65.1 cm3 (group A); 8.24/2.26; 63.1 cm3 (group B); and 10.1/2.69; 53.1 cm3 (group C) (P = 0.23; P = 0.39; P = 0.24). There were 26 clinical failures. The cumulative probabilities of clinical success at 18 months were 76.7% in group A, 82.6% in group B, and 83.3% in group C (P = 0.68). Nontarget embolization was prevented in 6 patients by coil embolization. All adverse events were mild and self-limited with rates of 86.0% in group A (37 of 43); 41.3% in group B (19 of 46); and 58.3% in group C (28 of 48) (P < 0.001). Dysuria was the most frequent adverse event (28 of 137 [20.4%]).ConclusionsPAE outcomes were not significantly different among microspheres of different sizes. The use of 100- to 300-μm microspheres was associated with an increased risk of minor adverse events. 相似文献

Purpose
To evaluate the safety and efficacy of prostatic artery embolization (PAE) using the combination of 50-μm and 100-μm polyvinyl alcohol (PVA) particles versus 100-μm PVA particles alone in the treatment of patients with symptomatic benign prostatic hyperplasia (BPH).Materials and Methods
Over a 5-year period, 120 patients treated with PAE for lower urinary tract symptoms (LUTS) secondary to BPH were randomized to undergo embolization with 50-μm plus 100-μm PVA particles (group A) or 100-μm PVA particles alone (group B). Mean follow-up time was 34 months (range, 12–57 mo). There were no differences between groups regarding baseline data. Primary outcome measurements included change in International Prostate Symptom Score (IPSS) and incidence of adverse events. Secondary outcome measurements included procedure-associated pain, prostate ischemia measured on magnetic resonance (MR) imaging 1 week after PAE, and changes over time in quality of life (QOL) questionnaire, peak urinary flow rate (Qmax), postvoid residual (PVR) volume, prostate volume (PV), prostate-specific antigen (PSA) level, and International Index of Erectile Function (IIEF) were evaluated. Recurrence of LUTS following PAE was defined as relief of LUTS temporally but increased IPSS ≥ 8 or QOL score ≥ 3 or decrease in Qmax to < 7 mL/s.Results
Mean follow-up periods were 35 months ± 22 in group A and 33 months ± 25 in group B (P = .629). No differences between groups regarding procedural details, pain scores, or adverse events were noted (P > .05). At 24 month of follow-up, patients in group A had a greater decrease in mean IPSS (18.7 ± 12.5 vs 14.8 ± 13.5), QOL score (3.7 ± 1.5 vs 2.4 ± 1.8), Qmax (10.5 mL ± 9.5 vs 6.8 mL ± 5.0), PVR (92.0 mL ± 75.0 vs 60.0 mL ± 55.0), and PV (37.0 mL ± 19.5 vs 25.5 mL ± 15.0) compared with patients in group B (P < .05 for all). Mean ratios of prostate ischemic volume at 1 week after PAE were 70% ± 20 in group A and 41% ± 25 in group B (P = .021); mean PSA levels at 24 hour after PAE were 92.5 ng/mL ± 55.0 in group A and 77.5 ng/mL ± 45.0 in group B (P = .031); LUTS recurrence rates were 3.6% in group A and 14.6% in group B (P = .024). The mean IIEF-5 was not significantly different from baseline in either group.Conclusions
PAE with 50-μm plus 100-μm PVA particles resulted in greater improvement in clinical and imaging outcomes and no significant differences in adverse events compared with 100-μm PVA particles alone. 相似文献4.
