ABSTRACT
Objective: We present our experience with photoselective vaporization (PVP) of the prostate by KTP laser for symptomatic benign prostatic hyperplasia reporting the efficacy and safety as well as clinical outcomes of the procedure.
Materials and methods: From June 2006 to January 2008 a total of 150 patients with symptomatic and obstructive benign prostatic hyperplasia were treated with an 80 W potassium-titanyl-phosphate laser. Preoperative evaluation included digital rectal examination (DRE), American Urological Association Symptom Index (AUASI) score, quality of life score (QOL), peak urinary flow rate (Qmax), post-void residual urine volume (PVR) and suprapubic ultrasound prostate volume measurement. Patients were evaluated at 1, 3, 6 and 12 months following treatment. At each follow up evaluation, side effects and efficacy parameters were measured.
Results: Mean lasing time was 72.7 minutes and mean prostate volume was 72 ml. There was no significant blood loss or fluid absorption during or immediately after PVP. Significant improvements in AUA-SI score, QOL score, Qmax and PVR were noted as early as 1 month after PVP treatment. At 12 months the mean AUA-SI score decreased from 11.8 to 3.2 (70% improvement) and the Qmax increased from 6.75 to 19.7 ml per second (191% improvement). PVR decreased from 336 to 25 ml (92.5% improvement). No major complications were noted.
Conclusions: PVP is a safe and effective outpatient procedure with low morbidity and excellent long term results. In our experience, results are seen as soon as 1 month after surgery and persist through follow-up.
