TURP术后尿道狭窄的影响因素探讨

目的探讨经尿道前列腺电切术(TURP)术后尿道狭窄的影响因素,避免发生。方法在施行TURP术患者400例中,除外死亡和外出28例,比较尿道狭窄29例(狭窄组)和未发生343例(对照组)在首次手术时的相关指标。结果狭窄组阴茎短小者6例(20.7%),切除腺体组织重量小于12g 14例(48.3%),合并前列腺炎15例(51.7%),气囊导尿管压缩牵引21例(72.4%),气囊导尿管大腿胶布固定8例(27.6%);而对照组依次为6例(1.75%)、28例(8.2%)、34例(9.9%)、81例(23.6%)和258例(75.2%),二者差异有统计学意义。狭窄组手术时间大于1h 3例(10.3%),对照组34例(9.9%),差异无统计学意义(P>0.05)。结论阴茎短小、腺体组织切除量少、合并前列腺炎及气囊导尿管阴茎压缩牵引是尿道狭窄发生的重要影响因素;而手术时间长短对狭窄发生无明显影响。

Discussion on influential factors of urethral stricture after TURP

Objiective To discuss the influential factors of urethral stricture after TURP for avoiding its occurrence.Methods To compare the correlative indexes between urethral stricture(28 cases) and no urethral stricture(343 cases) in 400 patients treated by TURP except 28 patients from death and other reason.Results In urethral stricture group :penis short and small in 6 patients,ablated glandular weight <12g in 14 patients,prostatitis in 15 patients,urethral catheter traction in 21 patients,urethral catheter fixed upper leg in 8 patients.In no urethral stricture group there were 6,28,34,81,258 cases,respectively.Operation time of urethral stricture was over 1h in 3 patients for the urethral stricture group and 34 patients for the control group with no statistical significance(P>0.05).Conclusion Penis short and small,less ablated glandular tissue,prostatitis and urethral catheter traction are the important factors of urethral stricture caused by transurethral resection of prostate,and yet operation time was no obvious effect on urethral stricture.
