报告经尿道高频电气化术（TVP）治疗特大前列腺增生症（BPH）56例。手术前后前列腺国际症状评分（I－PSS）平均下降23．09分，最大尿流率（Qmax）平均增加9．89ml／s，膀胱残余尿平均下降191．28ml，随访3～13个月，疗效稳定。对前列腺生重量与膀胱输出口梗阻（BOO）之间的关系及TVP治疗特大BPH的优劣进行讨论，认为重量特大的腺体延长和压迫后尿道是造成BOO的主要机械性因素，TVP能有效解除其梗阻，改善尿流，提高生活质量。
Report Transurethral electrosurgery (TVP) in the treatment of extra-benign prostatic hyperplasia (BPH) 56 cases. Preoperative and postoperative I-PSS score decreased 23.09 points, the maximum flow rate (Qmax) increased 9.89ml / s, bladder residual urine average decreased 191.28ml, followed up for 3 to 13 months, the effect stable. The relationship between BPH and bladder outlet obstruction (BOO) and the pros and cons of TVP for the treatment of extraordinarily large BPH are discussed. It is believed that the prolonged and oppressed posterior urethra is the main mechanical factor causing BOO and TVP is effective Relieve obstruction, improve urinary flow and improve quality of life.
