Laser coagulation of the prostate has been performed using a bare fiber passed through a sidefiring Albarran bridge containing a distal gold-plated reflector with a deflecting mechanism. The system and the fiber can be used for several dozen treatments. Transurethral laser coagulation with the new Albarran bridge and the noncontact Nd:YAG laser was performed on 45 patients for obstructive symptoms caused by benign prostatic hyperplasia. The dosimetry was 1000 J per 1 cc of prostatic tissue at 60 W for 60 seconds. Successful results were obtained in 38 patients (85%). A significant reduction in obstructive symptoms from a mean AUA-6 Symptom Score of 21.2 preoperatively to 9.1 at 3 months and 7.6 at 6 months was associated with an increase in the peak urine flow rate from 6.1 mL/sec preoperatively to 13.1 mL/sec at 3 months and 15.7 mL/sec at 6 months. The residual urine volume averaged 190 mL preoperatively and 35 mL at 6 months. Transurethral laser coagulation of the prostate represents a useful alternative to transurethral resection, especially in the high-risk patient with an enlarged median lobe or a small prostate. The treatment is bloodless and, with the aid of the modified Albarran bridge, can be performed with a standard urologic Nd:YAG laser. The new Albarran bridge also can reduce the cost of laser treatment.
使用一根裸光纤进行前列腺激光凝固术,该光纤穿过一个带有远端镀金反射器和偏转机制的侧射阿尔巴兰桥。该系统和光纤可用于几十次治疗。对45例因良性前列腺增生引起梗阻症状的患者,使用新型阿尔巴兰桥和非接触式Nd:YAG激光进行经尿道激光凝固术。剂量测定为在60瓦功率下,每1立方厘米前列腺组织给予1000焦耳能量,持续60秒。38例患者(85%)取得了成功结果。梗阻症状从术前平均AUA-6症状评分21.2显著降低至3个月时的9.1和6个月时的7.6,同时最大尿流率从术前的6.1毫升/秒增加至3个月时的13.1毫升/秒和6个月时的15.7毫升/秒。残余尿量术前平均为190毫升,6个月时为35毫升。经尿道前列腺激光凝固术是经尿道前列腺切除术的一种有用替代方法,尤其适用于中叶增大或前列腺较小的高危患者。该治疗方法无血,借助改良的阿尔巴兰桥,可使用标准的泌尿外科Nd:YAG激光进行操作。新型阿尔巴兰桥还可降低激光治疗成本。
