전립선비대증 환자에서 KTP laser를 이용한 전립선절제술의 치료효과 및 안정성에 대한 단기결과 = A Short-term Results on Efficacy and Safety of High Power (80W) KTP(Potassium-Titanyl-Phosphate) Laser Vaporization of the Prostate

다국어 초록 (Multilingual Abstract)

Purpose: Transurethral resection of the prostate (TURP) is the gold standard treatment for
symptomatic benign prostate hyperplasia, but significant complications are associated with this
procedure. The aim of this study was to compare the standard TURP with the high power (80W)
potassium-titanyl-phosphate laser (KTP/532; Greenlights PVTM laser system; Laserscope, San Jose,
USA) to elucidate the efficacy and safety of laser treatment.
Materials and Methods: 47 consecutive men with symptomatic BPH underwent PVP with an
80W KTP laser. All underwent preoperative and postoperative evaluation, including
assessments of international prostate symptom score (IPSS), quality of life (QOL), peak urinary
flow rate (Qmax), post-void residual volume (PVR), prostate specific antigen (PSA), and ultrasound
prostate volume (PV). Secondary outcome parameters included surgical time, anesthesia, and length
of catheterization. Follow-up assessment occurred at 3 and 12 months.
Results: Mean age was 68±1.1 years. Mean operative time was 58±15.4 minutes. Mean catheterization
times were 12.3±1.6 hours. All efficacy parameters were significantly improved compared to
those obtained preoperatively. Complications included hematuria lasting 1 and 3 months (4.2%),
transient incontinence (4.2%), transient dysuria (10.6%), frequency (21.2%), urgency (12.7%) and
retrograde ejaculation (51%).
Conclusions: These results demonstrate that PVP is safe and efficacious for the treatment of
symptomatic BPH. Long follow-up will further validate this new modality as the standard for
surgical treatment of BPH. (J Korean Continence Soc 2008;12:64-67)
