Spinal cord injury (SCI) patients with a neuropathic bladder are more prone to develop catheter-induced urethral trauma than occurs in the general population because many of the SCI patients are on indwelling urethral catheter drainage, or intermittent urethral catheterisation is performed either by them or by their carers. The presenting symptoms of improperly positioned Foley catheter in SCI patients may be at times, peculiar to the SCI patients and these include profuse sweating, bypassing of the catheter, increased spasms, or rarely, full fledged features of autonomic dysreflexia. With the availability of the flexible cystoscope, cystourethroscopy has been performed safely on SCI patients who had sustained catheter-induced urethral trauma, on the bedside, with an immediate, and accurate diagnosis of the extent of urethral trauma, and the presence of urethral false passage(s). Further, flexible cystoscopy has helped to treat the patients with urethral trauma by introducing a flexible tip guide wire under vision into the urinary bladder via the normal urethral channel and subsequently, passing a 12 Fr. Foley catheter over the guide wire, thus avoiding the false passage(s) in the urethra. With this technique, it was possible to avert the need for suprapubic urinary diversion in those SCI patients who had sustained acute urethral trauma. Such endoscopic management of acute urethral trauma in SCI patients is described with illustrative case reports of eight patients seen during a 15 month period.
患有神经源性膀胱的脊髓损伤(SCI)患者比普通人群更容易发生导尿管引起的尿道创伤,因为许多SCI患者采用留置尿道导尿管引流,或者由他们自己或护理人员进行间歇性尿道插管。SCI患者中Foley导尿管位置不当的表现症状有时可能是SCI患者所特有的,包括大量出汗、导尿管旁流、痉挛加剧,或者很少见的完全自主神经反射异常症状。随着可弯曲膀胱镜的出现,已能在床边对因导尿管引起尿道创伤的SCI患者安全地进行膀胱尿道镜检查,从而立即准确诊断尿道创伤的程度以及尿道假道的存在情况。此外,可弯曲膀胱镜检查通过在直视下经正常尿道通道将可弯曲头导丝插入膀胱,随后将12F Foley导尿管沿导丝置入,避免了尿道假道,从而帮助治疗尿道创伤患者。采用这种技术,有可能避免对那些遭受急性尿道创伤的SCI患者进行耻骨上尿路改道。本文通过15个月期间所诊治的8例患者的病例报告,阐述了对SCI患者急性尿道创伤的这种内镜治疗方法。
