Abstract

OBJECTIVE:

To evaluate the feasibility, safety, and outcomes of men with symptomatic benign prostatic hyperplasia undergoing 532-nm GreenLight laser prostatectomy in the office-based setting.

MATERIALS AND METHODS:

From September 2007 to October 2011, 47 patients underwent office-based 532-nm GreenLight laser prostatectomy by a single surgeon. Patients were enrolled prospectively and preoperative, intraoperative, and postoperative parameters were then reviewed retrospectively. Statistical analysis was performed with Wilcoxon rank sum test with a P value ≤.05 being considered statistically significant.

RESULTS:

The mean patient age was 66 (range, 49-89); 91% of men were on an alpha-blocker preoperatively; mean (standard deviation; SD) prostate volume by transrectal ultrasound was 35.8 mL (14.5); mean (SD) American Society of Anesthesiologists score was 2.33 (0.77); mean (SD) operative time was 36.73 minutes (18); mean (SD) lasing time was 19.1 minutes (8.31); mean (SD) total laser kiloJoules used was 85,387 kJ (38,885); and mean (SD) follow-up time was 8.48 months (8.24). The 1-year decrease in mean (SD) American Urologic Association Symptom Score and quality of life were 17.7 (8.3)-7 (7.3) and 4.1 (1.4)-2.27 (2) respectively. The maximal urinary flow increased from 8.1 (3.8) to 10.7 (6). Patients' postvoid residual improved from 130 mL (147) to 27 mL (55) over a 1-year period. (P <.01 for all). There were no reoperations for refractory lower urinary tract symptoms or hospital admissions.

CONCLUSION:

For men with small but symptomatic benign prostatic enlargement, office-based GreenLight laser prostatectomy is safe and feasible.
