Neurogenic bladder dysfunction due to spinal cord injury poses a significant threat to the well-being of patients. Incontinence, renal impairment, urinary tract infection, stones, and poor quality of life are some complications of this condition. The majority of patients will require management to ensure low pressure reservoir function of the bladder, complete emptying, and dryness. Management typically begins with anticholinergic medications and clean intermittent catheterization. Patients who fail this treatment because of inefficacy or intolerability are candidates for a spectrum of more invasive procedures. Endoscopic managements to relieve the bladder outlet resistance include sphincterotomy, botulinum toxin injection, and stent insertion. In contrast, patients with incompetent sphincters are candidates for transobturator tape insertion, sling surgery, or artificial sphincter implantation. Coordinated bladder emptying is possible with neuromodulation in selected patients. Bladder augmentation, usually with an intestinal segment, and urinary diversion are the last resort. Tissue engineering is promising in experimental settings; however, its role in clinical bladder management is still evolving. In this review, we summarize the current literature pertaining to the pathology and management of neurogenic bladder dysfunction in patients with spinal cord injury.
脊髓损伤所致神经源性膀胱功能障碍对患者的健康构成重大威胁。尿失禁、肾功能损害、尿路感染、结石以及生活质量低下是该病症的一些并发症。大多数患者需要进行治疗,以确保膀胱的低压储尿功能、完全排空以及保持干爽。治疗通常始于抗胆碱能药物和清洁间歇性导尿。因治疗无效或不耐受而未能从这种治疗中获益的患者可考虑一系列更具侵入性的手术。用于缓解膀胱出口阻力的内镜治疗方法包括括约肌切开术、肉毒杆菌毒素注射和支架置入。相比之下,括约肌功能不全的患者可考虑行经闭孔尿道中段吊带术、悬带手术或人工括约肌植入术。在部分患者中,神经调节可实现膀胱的协调排空。膀胱扩大术(通常采用肠段)和尿流改道是最后的治疗手段。组织工程在实验环境中前景广阔;然而,其在临床膀胱管理中的作用仍在不断发展。在本综述中,我们总结了目前有关脊髓损伤患者神经源性膀胱功能障碍的病理学和治疗的文献。
