Abstract
We describe the laser coagulation of the prostate using a conventional bare fiber inserted in a modified Albarran bridge which presents at the distal tip, a newly designed gold-plated reflector, connected by a deflecting mechanism. This allows delivery of laser energy (40 - 80 W) by direct reflection of the Nd:YAG laser light, an angularity more accentuated compared with other systems. Transurethral laser coagulation was performed on 25 patients for prostatic obstruction benign prostatic hyperplasia (BPH) and 6 selected patients for carcinoma of the prostate (December 91 - January 93). Patient selection (BPH) was limited to median lobe (range 50 - 55 years), small prostates, older and high-risk patients. Successful results were noted in 20 of the 25 cases of BPH group (80%). A significant reduction of obstructive symptoms was associated with an increase of maximal a medium flow rates. In the early prostate cancer group, the method has resulted in 3 patients with no evidence of disease, despite repeated biopsy, biochemical, and clinical investigations (PSA range level > 20 ng/ml to < 0.5 ng/ml at one year). The results are encouraging at this stage.
