前列腺增生术后后尿道狭窄的腔内治疗

目的：探讨前列腺增生术后后尿道狭窄的原因及腔内治疗效果。方法：回顾性分析109例前列腺增生术后后尿道狭窄患者的诊断和治疗资料。结果：71例为经尿道电切(电气化)术TUR(V)P术后，38例为开放性前列腺切除术后；出现后尿道狭窄的时间分别为：术后1年内81％(88／109)，1—2年10％(11／109)，2年以后9％(10／109)。所有患者均在直视下经导丝引导行后尿道狭窄切开加电切术，术中发现膀胱颈口狭窄40例，前列腺部及膜部尿道狭窄69例。术后平均随访36个月(12—70个月)，随访率74．3％(81／109)，排尿满意率为84．0％(68／81)。结论：前列腺增生术后后尿道狭窄部位多在膀胱颈口及前列腺部、膜部尿道，腔内治疗是一有效手段。

Endoscopic therapy of post-operative benign prostatic hyperplasia with posterior urethral stricture

Purpose:To investigate the cause of post-operative urethral stricture (POUS) and evaluate the en-doscopic therapy. Methods: Analyze the diagnosis and treatment in 109 BPH patients with POUS admitted from 1994 - 2000 retrospectively. Results:Seventy one cases were post-TUR( V)P, and 38 cases were post-open surger-y. Among all cases, bladder orifice stricture was found in 40 cases, prostatic and membranous urethral stricture was found in the rest cases. All Patients received urethrotomy. After 36 months follow-up, 84. 0% cases (68/81) had satisfactory urination. Conclusions;POUS is mainly located in bladder orifice, prostatic and membranous urethra. Endoscopic therapy is effective in POUS patients.
