High-power potassium titanyl phosphate laser vaporization prostatectomy

Area of Science:

• Urology
• Minimally Invasive Surgery
• Laser Technology

Background:

• Transurethral resection of the prostate (TURP) is a common treatment for benign prostatic hyperplasia (BPH), but it can be associated with significant morbidity.
• Alternative laser prostatectomy techniques have been explored to reduce morbidity.
• Neodymium:yttrium-aluminum-garnet (Nd:YAG) laser prostatectomy causes necrotic tissue, leading to temporary obstruction, while potassium titanyl phosphate (KTP) laser offers tissue vaporization with minimal coagulation.

Purpose of the Study:

• To evaluate the efficacy and safety of 60-W KTP laser prostatectomy for symptomatic benign prostatic hyperplasia (BPH).

Main Methods:

• Outpatient KTP laser prostatectomy was performed on 10 patients (age 52-80) with symptomatic BPH.
• Urinary flow rates were measured preoperatively and within 24 hours post-procedure.
• Adverse events were monitored during a 24-hour observation period.

Main Results:

• Mean peak urinary flow rate significantly increased from 8.0 mL/s preoperatively to 19.4 mL/s within 24 hours post-procedure.
• No patients experienced hematuria, dysuria, or incontinence after catheter removal.
• Two patients developed transient fever, and one experienced urgency during the observation period.

Conclusions:

• KTP laser vaporization prostatectomy is an effective treatment for BPH, providing immediate relief from obstructive symptoms.
• The procedure is associated with minimal morbidity, including absence of dysuria and incontinence.
