    Abstract:
    OBJECTIVE: To analyse the effect of prostate size on the outcome of holmium laser enucleation of prostate (HoLEP, an established procedure for treating symptomatic benign prostatic hypertrophy, BPH), in the initial 354 patients at 1 year of follow-up. PATIENTS AND METHODS: We retrospectively reviewed the records of 354 patients who had HoLEP at our institution from April 2003 to March 2007. In 235 patients the prostate weighed <60 g (group 1), in 77 it weighed 60-100 g (group 2) and in 42 >100 g (group 3). Demographic data and perioperative variables were recorded and compared among the three groups. RESULTS: The mean prostate size was 38.1, 76.4 and 133.5 g for groups 1, 2 and 3, respectively (P < 0.001), and the respective mean weight of resected prostate was 18.47, 40.8 and 82.76 g, respectively (P < 0.001). The mean procedure efficiency increased from 0.36 g/min in group 1 to 0.49 g/min in group 2 and 0.58 g/min in group 3 (P < 0.001). The decrease in haemoglobin level after HoLEP was greater in group 3 than in the other groups. Overall, HoLEP resulted in a 75% reduction in American Urologic Association symptom score, a 225% increase in peak urinary flow rate and an 86% decrease in postvoid residual urine volume at 1 year of follow-up. Perioperative complications were evenly distributed among the three groups, except for a higher incidence of superficial bladder mucosal injury and stenotic complications in group 3. CONCLUSIONS: HoLEP is a safe and effective procedure for treating symptomatic BPH, independent of prostate size, and is associated with low morbidity. The efficiency of HoLEP increases with increasing prostate size.
