A total of 28 patients with symptomatic bladder outlet obstruction due to benign prostatic hyperplasia were treated by visual laser coagulation (VLAP) performed with the Myriadlase sidefiring neodymium: YAG laser fibre at 40 Watts power. The treatment was performed as an outpatient procedure using intraurethral gel anaesthesia and light intravenous sedation and analgesia. Prostatic volume was 32 g (18-90 g), and 650 Joule per gram prostatic tissue (516-1000 J/g) was administered. The patients were evaluated at mean 9.2 weeks. The mean operative time was 34 minutes. The procedure was very gentle, all patients tolerated it well and there was no bleeding. Most patients experienced some dysuria for three to four weeks after the procedure, two had severe symptoms. Two patients remained in retention and required transurethral resection. The rest expressed subjective satisfaction with the results. Peak urinary flow increased from mean 9.0 ml/sec preoperatively to 15.4 ml/sec; a mean increase of 78%. One patient developed clinical urinary tract infection. There were no other complications of clinical significance.
共有28例因良性前列腺增生导致有症状膀胱出口梗阻的患者接受了可视化激光凝固术（VLAP）治疗，使用Myriadlase侧向发射钕:钇铝石榴石激光光纤，功率为40瓦。治疗作为门诊手术进行，采用尿道内凝胶麻醉和轻度静脉镇静镇痛。前列腺体积为32克（18 - 90克），每克前列腺组织给予650焦耳（516 - 1000焦/克）。患者平均在9.2周时接受评估。平均手术时间为34分钟。该手术非常温和，所有患者耐受性良好，且无出血情况。大多数患者在术后三到四周出现一些排尿困难，两名患者症状严重。两名患者仍有尿潴留，需要进行经尿道切除术。其余患者对结果表示主观满意。最大尿流率从术前平均9.0毫升/秒增加到15.4毫升/秒；平均增加78%。一名患者发生临床尿路感染。没有其他具有临床意义的并发症。
