目的　探讨开放性前列腺切除术的新术式。方法　采用对比研究方法 ,对良性前列腺增生 (BPH)患者 71例 ,随机分为三组。⑴治疗组 (采用缝扎膀胱下动脉保留后尿道前列腺切除术—改良Madigan术 ) 2 1例 ;⑵对照Ⅰ组 (采用Millin术 ) 18例 ;⑶对照Ⅱ组(采用经耻骨上膀胱前列腺切除术 ) 3 2例。观察其治疗效果。结果　全部病例 ,术后病理报告均为良性前列腺增生 (BPH)。治疗组无论在术中尿道损伤 ,出血量 ,术后膀胱冲洗天数 ,近期尿失禁 ,继发出血 ,尿路感染 ,膀胱痉孪 ,尿道狭窄 ,以及住院天数等方面 ,均优于对照组。结论　缝扎膀胱下动脉保留后尿道前列腺切除术具有术式简单 ,操作较容易 ,住院时间短 ,医疗费用少等优点 ,易于推广 ,具有较大的使用价值 Objective To explore a new technique of open prostatectomy. Methods A comparative study of 71 patients with benign prostatic hyperplasia (BPH) were randomly divided into three groups. (1) Treatment group (21 cases underwent surgical removal of posterior urethral prosthesis with modified suture of the bladder underwent modified Madigan operation); (2) Control group Ⅰ (Millin operation) 18 cases; Control group Ⅱ ) 32 cases. Observe the treatment effect. Results All the cases and postoperative pathological reports were benign prostatic hyperplasia (BPH). The treatment group was superior to the control group in terms of intraurethral urethral injury, bleeding volume, postoperative bladder irrigation days, recent urinary incontinence, secondary bleeding, urinary tract infection, cystospasm, urethral stricture, and hospital stay. Conclusions Posterior urethral resection of posterior urethral catheterization has the advantages of simple operation, easy operation, short hospital stay, low medical cost, easy to popularize, and great use value
