This study aimed to evaluate the feasibility of the prostate artery embolization (PAE) in the management of patients with benign prostatic hyperplasia (BPH) in different age groups, depending on the severity of voiding dysfunction, findings of the prostate ultrasound, and the ASA surgical risk.
The study comprised 39 patients with grade II-III BPH. Patients were divided into three groups, depending on the prostate volume and the grade of anesthesia risk. Patients of the group 1 (n=12), group 2 (n=19), and group 3 (n=8) underwent a classical transvesical prostatic adenomectomy (TPA), bipolar transurethral resection (TUR) of the prostate, and PAE, respectively. The treatment outcomes were assessed at 3 and 6 months after the operation.
When comparing the outcomes in three groups, a statistically significant difference in the IPSS was found both at 3 and 6 months when comparing TPA and TUR groups (p<0.0001) and PAE and TPA groups (p=0.0003). At 3 and 6 months after surgery, postvoid residual urine volume in the TPA and TUR group did not differ statistically significantly, but in the PAE group, it was significantly higher at 6 months than in the other two groups (p=0.004).
As a minimally invasive procedure, prostate artery embolization can become an alternative to TUR and one-stage TPA for patients with verified BPH and grade III ASA risk. This treatment modality can be performed in patients of any age and any prostate volume. The age of the patient does not significantly affect the outcomes of TPA, TUR, and PAE. To recommend this treatment modality as a method of choice, further multi-center, randomized trials are warranted involving longer study duration and larger patient groups.
本研究旨在评估前列腺动脉栓塞术(PAE)在不同年龄组良性前列腺增生(BPH)患者管理中的可行性,具体取决于排尿功能障碍的严重程度、前列腺超声检查结果以及美国麻醉医师协会(ASA)手术风险。
本研究纳入39例II - III级BPH患者。根据前列腺体积和麻醉风险等级将患者分为三组。第1组(n = 12)、第2组(n = 19)和第3组(n = 8)患者分别接受经典经膀胱前列腺腺瘤切除术(TPA)、双极经尿道前列腺切除术(TUR)和PAE。在术后3个月和6个月评估治疗效果。
比较三组的治疗效果时,TPA组与TUR组(p < 0.0001)以及PAE组与TPA组(p = 0.0003)在术后3个月和6个月时国际前列腺症状评分(IPSS)存在统计学显著差异。术后3个月和6个月时,TPA组和TUR组的残余尿量在统计学上无显著差异,但PAE组在术后6个月时残余尿量显著高于其他两组(p = 0.004)。
作为一种微创手术,对于确诊为BPH且ASA风险为III级的患者,前列腺动脉栓塞术可成为TUR和一期TPA的替代方法。这种治疗方式可用于任何年龄和任何前列腺体积的患者。患者年龄对TPA、TUR和PAE的治疗效果无显著影响。为将这种治疗方式推荐为首选方法,有必要进行进一步的多中心、随机试验,涉及更长的研究时间和更大的患者群体。
