1470nm激光直输光纤蜂窝式汽化技术在前列腺增生手术中的应用研究

Study of " honeycomb" evaporation technique with straight light beam of 1 470nm laser in treating benign prostatic hyperplasia

目的评估1 470nm激光直输光纤蜂窝式汽化技术治疗BPH的安全性及疗效。方法通过随访实施1 470nm直输光纤蜂窝式汽化技术的56例患者,对平均手术时间、术后膀胱冲洗时间、术后留置导尿管时间、手术并发症等指标进行分析,对国际前列腺症状评分(IPSS)、生活质量评分(QOL)、残余尿量(PVR)及最大尿流率(Qmax)改变等指标进行手术前后对比。结果平均手术时间(45.7±5.9)min,术后膀胱冲洗时间(10.0±1.2)h,术后留置导尿管时间(2.0±0.5)d,无严重并发症发生。IPSS及QOL评分由术前平均(26.0±1.9)、(6.0±0.6)分分别下降至(9.6±1.6)、(2.7±0.5)分,Qmax由术前(6.9±1.7)ml/s增加至术后(16.8±4.4)ml/s,PVR由术前(163.7±19.9)ml下降至术后(20.1±9.6)ml,手术前后比较差异均有统计学意义(P<0.05)。结论 1 470nm激光直输光纤蜂窝式汽化技术手术时间短,是一种安全、高效的微创手术。

Objective To evaluate the clinical efficacy and safety of utilizing ＂honeycomb＂ e vaporation technique with straight light beam of 1 470 nm to treat benign prostatic hyperplasia （BPH）. Methods We treated 56 patients with obstructive benign prostatic hyperplasia using 1 470 nm laser with ＂honeycomb＂ evaporation technique with straight light beam. Mean operative time, bladder irrigation time, catheterization period and surgical complications were measured and the fol- lowing variables were assessed before and after operation： IPSS, QOL, residual urine volume and maximum urinary flow rate（Qmax）. Results Mean operative time was （45.7±5.9）rain,bladder ir- rigation time was （10±1.2）h, catheterization period was （2±0.5） d. No severe complications occurred during perioperative period. Before and after operation, IPSS and QOL decreased from （26± 1.9） and （6±0.6） to （9.6±1.6） and （2.7±0.5）, Qmax increase from （6.94±1.7）ml/s to （16.8± 4.4） ml/s, residual urine volume decreased from （ 163.7 ±4 19.9） ml to （ 20.1 ± 9.6 ） ml. All results showed significant differences （P〈0.05）. Conclusions The ＂honeycomb＂ evaporation technique with straight light beam of 1 470 nm laser in treating benign prostatic hyperplasia is a high efficiency, short operation time consuming and safe minimally invasive treatment for BPH.
