经尿道双极等离子电切治疗重度前列腺增生症

Transurethral resection with bipolar plasma kinetic technique in the treatment of large volume benign prostate hyperplasia

目的探讨经尿道双极等离子电切治疗重度前列腺增生症的安全性和有效性。方法采用英国佳乐公司生产的双极等离子体系统经尿道切除重度前列腺增生72例,术后随访3月。观察术前、术后最大尿流率、前列腺症状评分和残余尿量的变化。结果前列腺质量平均(72.00±20.00)g,平均手术时间(82.00±36.00)min,术后平均留置尿管(4.00±1.00)d,术后平均住院时间(4.50±1.50)d,最大尿流率由术前的(6.00±1.50)ml/s上升至术后3个月的(14.10±4.70)ml/s,前列腺症状评分术前为(34.70±1.20)分,术后3个月降至(5.30±1.00)分,残余尿量从(150.00±80.00)ml降至(20.00±50.00)ml,三项指标术前术后比较差异均有统计学意义(t分别=27.31、254.64、25.92,P均<0.05),无前列腺电切综合征发生。结论经尿道双极等离子前列腺电切术治疗重度前列腺增生安全有效。

Objective To discuss the effect and safety of transurethral plasma kinetic vaporization of large volume prostate hyperplasia. Methods Seventy two cases of large volume prostate hyperplasia were treated with bipolar plasma kinetic （PKRP）. 3 months were followed up in 72 cases. The changes of maximum urinary flow rate（Qmax） ,international prostate symptom score （IPSS） , and residual urine volume before and after operation were observed. Results Average weight of dissected prostate tissue was （ 72.00 ± 20.00） g, Average operation time was （ 82.00 ±36.00） min, average catheter detention was （ 4.00 ± 1.00） days after operation, average postoperative stay was （4.50 ± 1.50） days. The peak flow rate increased from （6. 00 ± 1.50） ml/s to （ 14.10 ± 4.70） ml/s, IPSS scores decreased from （ 34.70 ± 1.20） to （5.30 ± 1.00） at 3 months after operation ; residual urine volume deceased from （ 150.00 ± 80.00） ml to （ 20.00 ± 50.00） ml. There were significant differences （ t = 27.31, 254.64, 25.92, P 〈 0.05） . No occurrence of transurethral resection syndrome. Conclusion PKRP is safe and effective in the treatment of large volume benign prostate hyperplasia.
