前尿道内支架管在治疗前尿道狭窄中的应用

目的:观察在前尿道狭窄患者中留置前尿道支架管的临床疗效。方法:选取2005年1月至2008年5月在本院住院治疗及进行门诊尿道扩张的患者共38例作为治疗组,并将同期在本院采取尿道扩张器扩张的患者38例纳入对照组,通过最大尿流率(Qmax)及扩张次数等指标对两组的临床疗效进行对比分析。结果:尿流率检测表明留置支架管后所有患者的Qmax均较术前明显增加,对拔管后6个月随访结果进行分析,治疗组Qmax>15ml/s的患者显著多于对照组(P<0.05)。结论:采用前尿道内留置支架管治疗前尿道狭窄不但显著减少扩张次数,减轻患者的经济负担,也显著改善患者的生活质量,前尿道狭窄患者中留置前尿道内支架管不失为临床上一种较好的治疗手段,并取得了良好的预期效果,简单易行,效果确切,值得推广。

Indwelling the anterior urethral stent: A good treatment option for anterior urethral stricture

Objective:To observe the clinical effect of indwelling the anterior urethral stent in the treatment of anterior urethral stricture.Methods:We included 38 patients with anterior urethral stricture in the treatment group,and another 38 in the control,the former treated by indwelling the anterior urethral stent,and the latter by urethral dilatation.Then we analyzed the clinical results by comparing the Qmax,urinary hesitancy and numbers of urethral dilations between the two groups.Results:Compared with the controls,the patients of the treatment group showed an obvious increase in Qmax,a significant decrease in the number of urethral dilatations,and a marked improvement of the quality of life.Six months after the stent removal,there were significantly more patients with Qmax > 15 ml/s in the treatment group than in the control (P < 0.05).Conclusion:Indwelling the anterior urethral stent is a desirable option for the treatment of anterior urethral stricture,which is simple,safe,effective and reliable,and can be applied to general clinical practice.
