男性留置导尿致尿道狭窄的相关因素及对策

目的了解留置导尿致尿道狭窄的相关因素及护理对策。方法回顾性分析58例因留置导尿引起尿道狭窄患者的置管时间、导尿管材料、型号及有无插管损伤。结果58例患者中，置管时间超过2周占69％（40／58）；应用橡胶导尿管占66％（38／58）；应用〉F18导尿管为67％（39／58）；插管时尿道有损伤占66％（38／58）。结论置管时间长、导尿管的毒性作用、尿管粗细选择不当、插管直接损伤是尿道狭窄的相关因素。缩短留置导尿管时间、选用硅胶导尿管、导尿管型号适合及避免不当操作可减少尿道狭窄的发生。

Evaluation on the correlation factors of male urethral stricture caused by urethral catheterization and nursing strategies

Objective To study the correlation factors and nursing strategies of urethral stricture caused by urethral catheterization. Method Analyze the time, material, size of caliber and injury of 58 cases with urethral stricture caused by catheterization retrospectively. Result In all cases, the proportion of urethral catheterization time beyond 2 weeks is 69 % （40/58）. The proportion of catheter made by rubber is 66% （38/58）, the caliber beyond F18 is 67% （39/58） and the injury during catheterization is 66 % （38/58）. Conclusion Long time of urethral catheterization, poisonous material, unsuitable size of catheter caliber and injury during procedure are the correlation factors of urethral stricture. A shorter time of urethral catheterization, catheter made by silica gel, a suitable size of catheter caliber and avoiding injury are the main preventive methods of urethral stricture.
