Text: Our main findings were that patients undergoing laser prostatectomy using the coagulation technique (visual laser ablation of the prostate) had higher reoperation rates (16 % versus 0 %, p = 0. 0199) and were 4 times more likely to have prolonged postoperative urinary retention (25 % versus 6. 3 %, p = 0. 0389), evaporation and coagulation were effective at relieving symptoms of prostatism with significant improvement in American Urological Association symptom scores and post-void residual urine volumes compared to baseline, improvement in peak flow rates was significantly greater in patients undergoing evaporation at 1, 3, 6 and 12 months (p < 0. 001) compared to coagulation, and a significantly greater amount of laser energy was required to evaporate a unit volume of prostate tissue compared to coagulation (2, 251 J. / cc versus 1, 036 J. / cc, p < 0. 03).
