[Evaluation of 80-W and 120-W GreenLight laser vaporization for benign prostatic hyperplasia in high-risk patients].
OBJECTIVE: To investigate and compare the effectiveness and safety of 80-W GreenLight laser vaporization and GreenLight high-performance system (HPS) 120-W laser vaporization for the treatment of benign prostatic hyperplasia (BPH) in high-risk patients.
METHODS: We allocated 290 high-risk patients with BPH to two groups to receive 80-W (n = 220) and HPS 120-W GreenLight laser vaporization (n = 70). We recorded and compared the pre-, intra- and post-operative clinical data of the two groups.
RESULTS: The operations were successful in both of the groups. There were statistically significant differences in the prostate volume, IPSS, Qmax and PVR before and after surgery (P < 0.01), but not between the two groups (P > 0.05). The operation time, lasing time and energy consumption were (56.5 +/- 22.6) min, (31.2 +/- 10.3) min and (159.8 +/- 29.0) kJ in the 80-W group, as compared with (45.1 +/- 20.4) min, (24.6 +/- 8.3) min and (134.2 +/- 23.3) kJ in the 120 W group, with significant differences between the two (P < 0.01).
CONCLUSION: GreenLight laser vaporization of the prostate is a safe and effective procedure for the treatment of BPH, and the new HPS 120-W laser therapy, with its advantages of easier operation and shorter surgical time, is an even better minimally invasive option for elderly high-risk patients.
