Abstract
Abstract Background and Purpose: Transurethral laser enucleation of the prostate (TLEP) using the potassium-titanyl-phosphate (KTP) laser offers an alternative technique to traditional photovaporization. The study objective was to determine the comparative efficacy between transurethral photovaporization of the prostate (PVP) with a TLEP technique using the 80W 532 nm KTP laser. Patients and Methods: A series of 97 vs 170 patients who underwent PVP vs TLEP, respectively, with the KTP laser system at Weill Cornell Medical College from September 2001 to May 2009 was studied retrospectively. Outcome measures included laser time, prostate volume lased per unit time, International Prostate Symptom Score (IPSS), postvoid residual (PVR), and maximum flow rate (Qmax). Statistical analyses were performed using the Shapiro-Wilk, Mann-Whitney, Wilcoxon, and unpaired t tests. Results: Baseline parameters were similar between groups, although volume was greater in the TLEP group (83 vs 63 cc, P=0.04). Median laser tim...
