ABSTRACT

Background: The criterion standard in benign prostatic hyperplasia (BPH) treatment has been transurethral resection of the prostate. However, in the last few years, alternative treatments have been developed to remove prostate tissue. One of these procedures is prostatectomy with laser vaporization of the tissues that provides instantaneous tissue reduction. The preliminary results of photovaporization with the diode laser in obstructive prostatic hyperplasia treatment are presented.
Aims: To prolectively evaluate the effectiveness of high power vaporization with a 980 nm diode laser for the treatment of urinary tract obstruction secondary to BPH, affecting the exit of urine.
Material and methods: A total of 15 patients were enrolled in the study. Inclusion criteria were a maximum flow of 12 mL per second or less, an emptying volume of 150 mL or more, a score of 12 or more using the International Prostate Symptom Score, and a score of 3 points or more for Quality of Life. Patients with a history of neurogenic micturition dysfunction, chronic prostatitis, or cancer of the prostate or bladder were excluded. Preoperative maximum flow, residual urine volume, the International Prostate Symptom Score, and the Quality of Life index were compared with results registered again after three months. Complications were documented.
Results: The evaluation at three months revealed a significant reduction in the mean score of the International Prostate Symptom Score and the average maximum flow rate increased significantly. The Quality of Life index changed considerably in relation to the baseline value. All values showed a slight improvement at the third month. The most frequent postoperative complications were retrograde ejaculation and irritative symptoms.
Conclusions: High power diode laser provided significant improvement in the International Prostate Symptom Score and in maximum flow and produced less morbidity.
