摘要：We prospectively compared the safety and efficacy of bipolar transurethral enucleation of the prostate (TUEP) versus 160-W lithium triboride laser (LBO) photoselective vaporization of the prostate (PVP) for treating benign prostatic hyperplasia >70 ml. Between February 2011 and December 2013, we treated 81 patients with benign prostatic hyperplasia >70 ml (39 using bipolar TUEP, 42 using PVP). There were no bleeding complications necessitating blood transfusion in either group. The operation time was comparable in the two groups (83.59 12.96 vs 89.60 20.18 min, P = 0.277). The PVP group had a shorter catheterization time (55.12 36.00 vs 110.00 24.57 h; P < 0.001) and postoperative stay (3.60 1.78 vs 5.82 1.05 days; P < 0.001) than the bipolar TUEP group. Neither group had severe perioperative complications. At 12 months postoperatively, the bipolar TUEP group had sustainable, statistically significant improvement according to the International Prostate Symptom Score (3.51 1.67 vs 5.12 2.31; P = 0.001), quality of life (0.75 0.63 vs 1.24 0.66; P = 0.001), maximum urinary flow rate (26.04 5.04 vs 22.49 4.93 ml s-1; P < 0.001), postvoid residual urine volume (10.59 4.62 vs 17.26 5.35 ml; P < 0.001), and prostate-specific antigen level (1.26 0.49 vs 2.20 0.85 ng ml-1; P < 0.001). Both bipolar TUEP and 160-W LBO PVP are safe and effective for treating benign prostatic hyperplasia >70 ml. Bipolar TUEP offers more complete removal of prostatic adenoma than 160-W LBO PVP. Our results indicated that the clinical efficacy of bipolar TUEP was more durable and favorable than 160-W LBO PVP at the12-month follow-up.
