Prospective evaluation of ambulatory laser vaporization of the prostate for benign prostatic hyperplasia.

BACKGROUND AND OBJECTIVE: Photoselective vaporization of the prostate (PVP) is an alternative to transurethral resection of the prostate in the surgical treatment of benign prostatic hyperplasia (BPH). Our objective was to prospectively evaluate the feasibility, safety, and efficacy of ambulatory photoselective vaporization of the prostate for benign prostatic hyperplasia. MATERIALS AND METHODS: We prospectively collected data of all consecutive patients who underwent ambulatory PVP with the Greenlight(®) laser 180-W XPS at two centers between May 2012 and June 2013. Patients' characteristics, perioperative data, postoperative outcomes, complications, and patient's satisfaction were evaluated. Successful ambulatory care procedure was defined as the ability to leave the hospital in the evening of the operation. RESULTS: The ambulatory procedure was intended in 134 patients. Mean age was 67 years. Mean prostate volume was 54 ml, and Median American Society Anesthesiologists (ASA) score was 2. Ambulatory procedure was successful in 121 patients (90%). At 3 months, International Prostate Symptom Score (7.3 ± 4.9), maximal urinary flow rate (20.8 ± 7.6 ml/s), postvoid residual urine (19.2 ± 71 ml), and quality of life (1.6 ± 1.4) were significantly improved (P < 0.001). Fourteen patients (10.5%) had complications that were all minor (Clavien ≤ 2). Two patients had to be readmitted to the hospital. The majority of patients (89%) were satisfied with ambulatory care. Failure to complete ambulatory procedure was mostly related to logistical problem (70% of the cases). CONCLUSIONS: Ambulatory PVP is feasible with functional results and complications comparable to that of traditional hospitalization. Ambulatory care yields high patient's satisfaction.
