STATEMENT OF PURPOSE:
Transurethral resection of the prostate (TURP) is the standard surgical intervention for obstructive benign prostatic hyperplasia (BPH) in all but the largest of glands, which are typically treated with open simple prostatectomy. Recently, new generation lasers (holmium and potassium titanyl phosphate \[KTP\]) have been utilized for BPH treatment. Long-term follow-up of laser prostatectomy outcomes must be documented to fully characterize the degree of voiding improvement achievable by these new techniques, the durability of these outcomes, and the safety profiles of these procedures.
