[Laser-TURP with a lateral firing fiber for contact irradiation].
We have operated 25 BPH patients with transurethral Nd-YAG laser ablation for prostate from June of 1993 till December of 1993. We used UltraLine fiber for contact laser irradiation of the prostate. This is a lateral firing quartz fiber with high density laser energy output, and so made it possible for us to vaporize prostatic tissue rapidly and deeply. We used 60 Watts of power for all cases. For the prostates larger than 50 cm3, limited resection after laser ablation allowed early relief of patients' symptoms. Two months after the treatment, average flow rate improved from 3.7 ml/sec to 7.8 ml/sec. Volume of residual urine decreased from 48.4 ml to 17.0 ml. Twenty-four percent decrease of prostatic volume was also recognized with transrectal sonography. Only 4 patients complained of transient urinary retention, although another 3 or 5 days catheter placement relieved their symptoms. Bleeding was negligible and the other postoperative complications were not recognized at all. Laser-TURP is a new treatment that is effective, less morbid and economical, compared with the ordinary TUR-P. So it will soon become an alternative method to electrocautery TUR-P.
