Catheter-free 120W lithium triborate (LBO) laser photoselective vaporization prostatectomy (PVP) for benign prostatic hyperplasia (BPH).
OBJECTIVE
We evaluate the safety and efficacy of catheter-free LBO laser PVP for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH).


METHODS
We prospectively evaluated our initial LBO laser PVP experience and the need for urethral catheterization.


RESULTS
Seventy consecutive patients were identified. 49 (70%) were discharged without (C-) and 21 (30%) were discharged with (C+) a urethral catheter. There were no significant differences in pre-operative parameters, including age (C-: 65+/-10 vs. C+: 69+/-9 years), AUASS (C-: 22+/-6 vs. C+: 21+/-6), Qmax (C-: 10+/-4 vs. C+: 8+/-3 ml/second), PVR (C-: 62+/-105 vs. C+: 57+/-82 ml) and prostate volume (C-: 65+/-35 vs. C+: 86+/-53 ml). There were no significant differences in laser time and energy usage. AUASS, Qmax and PVR values showed significant improvement within each group (P<0.05), but there were no significant differences between the two groups. All were outpatient procedures. 2/70 (2.9%) patients required catheter reinsertion in C+. The overall incidence of adverse events was low and did not differ between the two groups.


CONCLUSIONS
Our experience suggests that catheter-free LBO laser PVP is safe and effective for the treatment of LUTS secondary to BPH.
