【摘要】 目的 探讨经尿道超脉冲等离子体腔内逆行剜除汽化切除术治疗良性前列腺增生的有效性和安全性。 方法 2008年4月－2009年4月，应用Gyrus超脉冲等离子体行经尿道前列腺腔内逆行剜除汽化切除术124例，前列腺重量为（62.3±21.7） g。术中首先用电切镜鞘、电切环钝锐性相结合将前列腺增生腺体沿外科包膜逆行剥离、剜除，同时断血供，然后推至膀胱颈处后切除。统计手术时间、术中出血量及收集到的前列腺组织质量，术后留置尿管时间、住院时间、手术后前列腺特异性抗原（prostatic specific antigen，PSA）、残余尿量（post voiding residual volume，PVR）、最大尿流率（Qmax）、国际前列腺症状评分（international prostatic symptom scores，IPSS）及生活质量评分（quality of life，QOL）等指标的变化。 结果 124例手术顺利完成。手术时间（48.1±19.4） min，腺体组织质量（57.6±19.6） g，平均失血量（86.2±20.7） mL，仅1例需要输血，出血量和手术时间随前列腺体积和重量的增加而相应增加和延长。术后留置尿管时间（3.1±1.6） d，住院时间（5.8±1.4） d。随访6～18个月，所有患者术后1、6个月Qmax、PVR、IPSS、QOL均较术前得到改善，与术前比较差异均有统计学意义（Plt;0.05）。术后6个月血清PSA降至（0.90±0.26） ng/mL，与术前比较差异有统计学意义（Plt;0.05）。继发尿道外口狭窄3例，经尿道扩张治疗后恢复排尿通畅；继发尿失禁2例，经保守治疗分别于术后1～6个月恢复；无永久性尿失禁、再次手术止血患者，无手术死亡者，未发生经尿道前列腺电切综合征。 结论 经尿道超脉冲等离子体腔内逆行剜除汽化切除术治疗良性前列腺增生安全有效，值得临床推广使用。【Abstract】 Objective To evaluate the safety and clinical efficacy of superpulse plasmakinetic body in transurethral intracavitary retrograde enucleation and vaporization resection of the prostate (TUEVRP) for the treatment of benign prostatic hyperplasia (BPH). Methods Between April 2008 and April 2009, Gyrus TUEVRP was performed on 124 patients with obstructive BPH whose mean prostatic weight was (62.3±21.7) g. The hyperplasia prostate glands were retrogradely dissected and enucleated along surgical capsule to the bladder neck by sharp and blunt dissection combination of the resectoscope tip or loop. Simultaneously, the blood supply of the gland was clamped. The changes of such indexes as operating time, perioperative blood loss, collected prostatic specimen weight, postoperative catheterization time, hospitalization time, prostatic specific antigen (PSA), post voiding residual volume (PVR), maximum urinary flow rate (Qmax), international prostatic symptom score (IPSS), and quality of life (QOL) were assessed. Results All surgeries were successfully carried out with an average operation time of (48.1±19.4) minutes ranged from 25 to 175 minutes. The mean collected prostatic specimen weight was (57.6±19.6) g ranged from 20.2 to 125.7 g. The blood loss was ranged from 45 to 350 ml, averaging at (86.2±20.7) mL during the operation. Blood transfusion was needed in only one case. Blood loss and operation time were increased and prolonged in accordance with the increase of prostatic volume and weight. The postoperative catheterization time was ranged from 2 to 5 days, averaging at 3.1±1.6. The mean hospitalization time was (5.8±1.4) days ranged from 5 to 8 days. All patients were followed up for 6 to 18 months. Qmax, PVR, IPSS and QOL-score six months after operation were significantly improved compared with those before operation (Plt;0.05). There were three cases of external urethral stricture, and they were treated with urethral dilatation successfully. Two cases of urinary incontinence recovered 1 and 6 months later, respectively, by traditional treatment. There were no cases of permanent urinary incontinence, reoperation for hemostasis, operative death, or transurethral resection syndrome. Conclusion TUEVRP is safe and clinically efficacious in the treatment of BPH, and is worthy of clinical promotion.

Objective To compare the effectiveness and safety of transurethral plasma kinetic enucleation of the prostate (TPKEP) and transurethral resection of the plasma (TURP) in patients with benign prostate hyperplasia (BPH) on the basis of bipolar plasma kinetic technology. Methods Eighty BPH patients who met the included criteria were assigned to two groups according to block balanced randomization, of which, 40 received TPKEP and the others received PKRP. We conducted statistical analysis after recording the clinical outcomes including international prostate symptom score (IPSS), quality of life (QOL), maximum flow (Qmax), post void residual urine volume (PVR), rates of prostate coated perforation, blood loss in the operation, duration of operation, time of bladder irrigation, duration of indwelling catheter, post-operative adverse effects, etc. Results The two groups were consistent at baseline before operation. The results of the analysis of clinical outcomes showed that, the TPKEP group was superior to the TURP group in prostate coated perforation (2 cases vs. 8 cases), hemoglobin in flushing fluid (index of blood loss, 10.95±5.02 g vs. 15.8±5.86 g), duration of operation (45.13±11.22 min vs. 53.33±8.69 min), time of bladder irrigation (12.58±2.77 h vs. 22.1±2.33 h), duration of indwelling catheter (65.13±10.67 h vs. 84.5±5.67 h), post-operative irritation sign of the bladder and urethra (5 cases vs. 12 cases), and the event of indwelling catheter after removal (0 cases vs. 4 cases), with significant differences; however, the TPKEP group was higher than the TURP group in the incidence of transient uracratia (10 cases vs. 3 cases), with a significant difference. The results of a 6-month follow-up showed that, no significant difference was found between the two groups in IPSS (2.78±1.03 vs. 2.40±1.13), QOL (1.28±0.45 vs. 1.45±0.51), Qmax (21.10±2.68 vs. 20.58±2.57), and PVR (2.82±2.90 vs. 2.18±2.27), respectively (Pgt;0.05). Long-term uracratia, urethrostenosis and secondary bleeding were not observed after operation in both groups. Conclusions TPKEP and TURP were alike in the short-term effectiveness of operation. TPKEP is safer than the TURP, which is regarded as a fairly ideal method for treating symptomatic BPH. However, the long-term effectiveness of TPKEP is yet to be further proved by large-scale randomized controlled trials with long-term follow-up.

Objective Evidence-based medicine was used to make an individualized treatment plan for newly diagnosed prostatic hyperplasia in an elderly patient. Methods After clinical problems were discovered, evidence was collected from CBM, CNKI, The Cochrane Library, PubMed, EMBASE, ScienceDirect, Springer, and ProQuest databases according to our predefined search strategy. The search was done through 2008. The internal and external validity of the evidence was assessed. The evidence, combined with the patient value, was applied to the patient. Results A total of 39 systematic reviews involving 137 randomized controlled trials were identified. A rational treatment plan was made upon a critical evaluation of the data. After one year follow-up, the treatment protocol was proven correct. Conclusion The treatment efficacy in newly diagnosed prostatic hyperplasia in the elderly has been improved by determining an individualized treatment protocol according to evidence-based methods.
ObjectiveTo evaluate the safety and clinical efficacy of transurethral holmium laser enucleation of the prostate (HoLEP) versus transurethral plasma kinetic enucleation of the prostate (PKEP) in the treatment of benign prostate hyperplasia (BPH).MethodsRandomized controlled trials of HoLEP versus PKEP in the treatment of BPH published between January 2000 and March 2021 were searched in PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Chongqing VIP database, and Wanfang database. Operative duration, estimated intraoperative blood loss, average duration of urinary catheterization, average duration of bladder irrigation, average length of hospital stay, and postoperative complications were used as safety evaluation indicators. Postoperative International Prostatic Symptomatic Score (IPSS), postoperative maximum urinary flow rate (Qmax), postoperative quality of life (QoL), and postvoid residual (PVR) were used as effective evaluation indicators.ResultsA total of 14 randomized controlled trials were included in this study, with a total of 1 478 patients (744 in the HoLEP group and 734 in the PKEP group). The results of the meta-analysis showed that the intraoperative blood loss in the HoLEP group was less than that in the PKEP group [weighted mean difference (WMD)=−25.95 mL, 95% confidence interval (CI) (−31.65, 20.25) mL, P=0.025], the average duration of urinary catheterization [WMD=−10.35 h, 95%CI (−18.25, −2.45) h, P=0.042], average duration of bladder irrigation [WMD=−10.28 h, 95%CI (−17.52, −3.04) h, P=0.038], and average length of hospital stay [WMD=−1.24 d, 95%CI (−1.85, −0.62) d, P=0.033] in the HoLEP group were shorter than those in the PKEP group, and the incidence of postoperative complications [risk ratio=0.70, 95%CI (0.56, 0.87), P=0.047] and 6-month postoperative Qmax [WMD=−0.89 m/s, 95%CI (−1.74, −0.05) m/s, P=0.037] in the HoLEP group were lower than those in the PKEP group. However, there was no significant difference in the operative duration, 3-month postoperative IPSS, 3-month postoperative Qmax, 3-month postoperative QoL, 3-month postoperative PVR, 6-month postoperative IPSS, 6-month postoperative QoL, or 6-month postoperative PVR between the two groups (P>0.05).ConclusionsIn the treatment of BPH, the effectiveness of HoLEP does not differ from that of PKEP, but HoLEP is safer. The conclusions of this study need to be verified in more precisely designed and larger sample-sized multi-center randomized controlled trials.
Objective To evaluate the effect of pretreatment with epristeride on decreasing intraoperative bleeding during transurethral resection of prostate (TURP) and to study its mechanism. Methods A total of 60 patients with benign prostatic hyperplasia undergoing TURP were divided into two groups: 30 patients were pretreated with epristeride 5 mg×2 daily for 7 to 11 days before TURP, and 30 patients did not receive any pretreatment. The operations for the two groups of patients were conducted by the same doctors. The operation time, the weight of resected prostatic tissue, and the volume of irrigating fluid were recorded. Blood loss, bleeding index, and bleeding intensity were calculated. Microvessel density (MVD), vascular endothelial growth factors (VEGF), and nitric oxide synthase type III (eNOS) expression were measured by the immunohistochemistry SPmethod in prostatic tissue. Results In the epristeride and control groups, the mean blood loss was 179.51±78.29 ml and 237.95±124.38 ml (Plt;0.05); the mean bleeding index was 7.68±3.94 ml/g and 9.73±3.42 ml/g (Plt;0.05); the mean bleeding intensity was 2.43±1.03 ml/min and 3.30±1.50 ml/min (Plt;0.05); the mean value of MVD was 18.80±5.68 and 23.70±4.91 (Plt;0.05); the mean rank of VEGF was 23.48 and 31.77 (Plt;0.05); and the mean rank of eNOS was 22.36 and 31.14 (Plt;0.05), respectively. Conclusion Pretreatment with epristeride decreases intraoperative bleeding during TURP. The preliminary results suggest that angiogenesis in the prostatic tissue is suppressed.
