Life expectancy and physical fitness of patients with neurogenic bladder dysfunctions is highly dependent on the urine status of the patient, and on the integrity and function of the upper urinary tract. Residual urine and urine incontinence give rise to infections, a vicious circle which ends with uraemia. Following nerve disorders can be the cause of a bladder dysfunction with outflow obstruction thus bearing the risk of ascending urine infection: 1) complete or incomplete spinal cord lesion, 2) myelomeningocele, 3) diseases of the CNS, 4) peripheral neuropathy (diabetes, chronic alcoholism, infectious diseases), 5) effect or side-effect of medications. An infravesical obstruction can occur at the alpha-adrenergic receptor site, at the level of the bladder neck or at the level of the striated external sphincter. The latter condition was termed detrusor-sphincter-dyssynergia. Instrumental bladder emptying for prevention of UTI can be achieved by: 1) catheterisation, 2) intermittent self catheterisation, 3) indwelling catheter--should be avoided for long term drainage, 4) suprapubic bladder drainage (cystocath)--the best treatment option for emptying the bladder and to avoid infections.
神经源性膀胱功能障碍患者的预期寿命和身体健康状况高度依赖于患者的尿液状态以及上尿路的完整性和功能。残余尿和尿失禁会引发感染,最终导致尿毒症,形成恶性循环。以下神经紊乱可能是导致膀胱功能障碍并伴有流出道梗阻的原因,从而存在上行性尿路感染的风险:1)完全或不完全脊髓损伤;2)脊髓脊膜膨出;3)中枢神经系统疾病;4)周围神经病变(糖尿病、慢性酒精中毒、传染病);5)药物的作用或副作用。膀胱下梗阻可发生在α-肾上腺素能受体部位、膀胱颈水平或横纹肌外括约肌水平。后一种情况被称为逼尿肌-括约肌协同失调。预防尿路感染的器械性膀胱排空可通过以下方式实现:1)导尿;2)间歇性自我导尿;3)留置导尿管——应避免长期引流;4)耻骨上膀胱引流(膀胱造瘘)——排空膀胱并避免感染的最佳治疗选择。
