benign prostatic hyperplasia, treatment, laser vaporization


Benign prostatic hyperplasia (BPH) affects about 70% of men aged more than 60 years. The "gold standard" treatment modality is transurethral resection of the prostate (TURP). One of the newest tool of BPH treatment is laser enriched with potassium-titanium-phosphoric crystal.
materials and methods
Between August 2003 and July 2004 58 men were treated with photo selective vaporization of the prostate with high-energy potassium-titanium-phosphoric laser. 32 patients with follow-up longer than 12 weeks (from 12 to 30 weeks) were included to the study. Prostate volume ranged from 31 to 136 cm3. All of them had International Prostatic Symptoms Score (I-PSS) exceeding 21 points and quality of life (QoL) of less than 3 points. Peak urinary flow before treatment ranged from 7,2 to 14 ,1 ml/s.
Mean operation duration was 17 minutes. All procedures were performed during intravenous anesthesia. Foley catheter was left after the procedure in 1 patients whereas 2 patients were additionally catheterized during the first 24 hours after the procedure. Increased body temperature mounted to 38 degrees was noted in 2 patients during the first 24 hours after the operation. Hematuria requiring catheterization occurred in one patent during the first day after the procedure. During the seventh day after the operation hematuria was observed in 4 patients (2 of them were hospitalized). ReTURP was performed in 1 patient 4 weeks after the operation. Four weeks after the procedure IPSS decreased by about middling 9 points, peak urinary flow ranged from 11,3 to 17,1 ml/s. 12 weeks after the procedure peak urinary flow ranged from 15,1 do 22,8 ml/s.
Photo selective vaporization of the prostate decreased severity of obstructive symptoms in all 32 patients 12 weeks after the operation. Peak urinary flow was increased in analyzed men 12 weeks after the procedure. Short follow-up does not allow to create definitive conclusions, however presented results are encouraging and photo selective vaporization of the prostate should be continued.
