应用激光经尿道非接触式照射治疗前列腺增生症２０６例，其中１３例需再次手术，占６．３％。分析其原因分别为尿道狭窄、膀胱颈部挛缩、前列腺增生腺体残留、继发性出血，其中腺体残留占再手术人数的６１．５％。由此说明激光治疗前列腺增生具有创伤小、出血少、恢复快等优点，是一种简单有效的治疗方法，但汽化的范围和深度值得进一步研究。 206 cases of benign prostatic hyperplasia were treated with laser transurethral non-contact irradiation, of which 13 cases required reoperation, accounting for 6.3%. Analysis of the reasons were urethral stricture, bladder neck contracture, prostate gland gland residue, secondary hemorrhage, which accounted for 61.5% of residual glands. This shows that laser treatment of benign prostatic hyperplasia with less trauma, less bleeding, rapid recovery, etc., is a simple and effective treatment, but the scope and depth of vaporization deserves further study.
