方法对79例患者行自由尿流率及尿动力学检查，其中无膀胱出口梗阻（BOO）组37例，良性前列腺梗阻组27例，尿道狭窄组15例。

Methods Free uroflometry and urodynamic studies were undertaken in 79 patients .

A、B两组IPSS评分及前列腺部尿道狭窄百分比明显高于C组（P<0.05）；

I-PSS score and the percentage of urethra stricture in prostatic portion of group C were significantly lower than those of groups A and B ( P < 0.05 ) .

结论尿道狭窄、膀胱功能异常和腺体残留是TURP术后排尿异常的常见原因。

Conclusions Urethral stricture , bladder dysfunction and residual prostate tissue are the common causes of urination difficulty after TURP .

RRP组术后尿道狭窄1例。

There was one case with urethral stricture in RRP group .

上置法植骨技术与种植修复Onlay、Duckett术后均没有尿道狭窄。

No stricture was found in Onlay or Duckett method .

方法采用Rudolf冷刀和电切镜对23例尿道狭窄患者施行尿道内切开，术后留置导尿管4～6周，必要时行规律定期尿道扩张。

[ Methods ] 23 patients with urethral stricture accepted internal urethrotomy and / or regular dilation were analysed .

9例术后3个月内再次出现尿道狭窄，采用自制单J管在尼龙线引导下行尿道扩张术。

Urethral stricture recurred in 9 patients 3 months after the operation , and they were all cured by performance of urethra dilatation with self-designed single J tube under the guidance of the medical nylon string .

平均住院天数35d，随访1～2a无骨盆畸形、尿道狭窄等后遗症。

Average hospitalization time were 35 days . Follow-up in 1 ~ 2 years showed no sequelae such as deformity of pelvic and urethrostenosis .

结果：MRI能清晰地显示伤后盆腔内解剖结构改变，前列腺的位置及其与耻骨联合的关系，准确测量尿道狭窄或闭锁的长度，显示疤痕的范围及深度。

Results : Pelvic MRI can clearly show the pelvic anatomic structures after crush injury and the position of prostate , the relationship with symphysis pubis , while MRI can correctly reveal the length of the urethral stricture and displace of prostatic apex .

尿道狭窄段切开、二期尿道成形（Johanson术）12例；

Two-stage urethroplasty of Johanson procedure in 12 ;

本组无TUR综合征，膀胱破裂、继发出血各1例（1.2%），前尿道狭窄11例（13.4%），无永久尿失禁发生。

Vesical rupture , and secondary bleeding were happened in 1 case respectively . Anterior urethral stricture was in 11 cases ( 13 4 % ) .

结论钬激光尿道狭窄切除术是治疗尿道狭窄的安全、有效、微创的方法。这一技术可以增加3dB带宽。

Conclusions Cut and resection of urethral stricture with holmium laser in endourethral way is a safe , effective and minimally invasive therapeutic technique .

方法后尿道狭窄患者46例，狭窄段长度0.8～2.5cm，平均1.5cm。

[ Methods ] This study included 46 cases of old posterior urethral stricture or atresia . The length of stricture segment was 0.8 to 2.5 cm with a mean of 1.5 cm .

彩色多谱勒显示前列腺内血流信号明显减弱、最大血流速度减慢，B超或CT检查前列腺体积从平均127ml缩小到90ml，缩小71%，X线造影尿道狭窄消失。

CT and B-ultrasound showed that the prostate volume was obviously decreased from 127 ml to 90 ml on average with a reduction rate of 71 % , and the urethral stricture disappeared on X-ray examination . Color Doppler imaging showed that the blood supply inside the prostate was reduced .

方法：对32例后尿道狭窄和闭锁患者采用膀胱截石位，于3、9、12点处作放射状钬激光（1.5J，10Hz）内切开治疗，并修整尿道内面，使管腔光滑。

Methods : With Holmium : YAG ( 1.5 J , 10 Hz ) direct incision the stricture at 3 or 9 and 12 o'clock sites , 32 men with posterior-urethral stricture and atresia were treated through transurethral endoscopy .

方法对76例尿道狭窄8cm以上的患者采用不同尿道成形术式治疗，其中不同黏膜重建尿道42例（结肠黏膜26例，膀胱黏膜6例，口腔黏膜10例）；

Methods Seventy-six patients with complex urethral stricture greater than 8 cm long underwent different procedures of urethroplasty . Of them various mucosa grafts urethral reconstruction were adopted in 42 cases ( colonic mucosal graft , n26 ; buccal mucosal graft , n10 ; bladder mucosal graft , n6 );
