1993年以来,我们采用美国产Trimid100型非接触式激光治疗仪经尿道治疗前列腺增生症患者43例,取得了满意效果。1 临床资料 患者年龄59～83岁,平均67岁。病程9个月至25年。术前均有排尿困难,急性尿潴留需留置导尿者4例。术前症状评分6～17分10例,18～25分27例,26～35分6例,平均18.3分。生活质量评分平均为4分。直肠指检示前列腺增生Ⅰ～Ⅱ°31例,Ⅲ°以上12例。最大尿流率平均为8.3ml/s,膀胱残余尿平均59ml,前列腺重量平均52.9g,血清PSA平均2.1ng/ml。2 方法 使用Trimid 100型非接触式掺钕钇铝石榴石激光(Nd:YAG)治疗仪,90°反射光导纤维及探头,Olympus膀胱尿道镜及Sony彩色电视监视系统。采用鞍麻或硬膜外麻醉。取截石位,经尿道插入膀胱尿道镜,观察 Since 1993, we use the United States Trimid100 non-contact laser treatment of transurethral treatment of 43 cases of benign prostatic hyperplasia, and achieved satisfactory results. A clinical data of patients aged 59 to 83 years, mean 67 years. Duration of 9 months to 25 years. All patients had dysuria before operation. Acute urinary retention required indwelling catheterization in 4 cases. Preoperative symptom score 6 to 17 points in 10 cases, 18 to 25 points in 27 cases, 26 to 35 points in 6 cases, an average of 18.3 points. The average quality of life score is 4 points. Rectal examination showed benign prostatic hyperplasia Ⅰ ~ Ⅱ ° 31 cases, Ⅲ ° 12 cases. The mean maximum flow rate was 8.3ml / s, bladder residual urine average 59ml, prostate weight average 52.9g, serum PSA average 2.1ng / ml. 2 Methods Trimid 100 non-contact neodymium-doped yttrium aluminum garnet laser (Nd: YAG) apparatus, 90 ° reflective optical fiber and probe, Olympus bladder urethra and Sony color TV monitoring system were used. Using saddle or epidural anesthesia. Take lithotomy position, transurethral insertion of the bladder urethra, observation
