[Urinary Bladder Cancer as a Long-term Sequela of Spinal Cord Injury - Relevance to Practice].

Urinary bladder cancer is the second most common tumour disease after lung cancer leading to death in people with a spinal cord injury. This paper provides a comprehensive overview of the differences relevant to urologists between urinary bladder tumours in this population compared with urinary bladder tumours in the general population.People with a spinal cord injury are 1 to 2 decades younger on average at the time of tumour diagnosis than patients without a spinal cord injury. Histopathologic findings at the initial diagnosis of urinary bladder cancer in people with a spinal cord injury are much less favourable than for urinary bladder cancers in the general population. Muscle-invasive tumours and tumours with poor differentiation are much more common, and the proportion of squamous cell carcinomas is significantly higher. The incidence rises after more than 10 years of paralysis. Urinary bladder cancer mortality is significantly elevated and increases with the duration of paralysis. In diagnostic procedures and, in particular, in radical cystectomy, clinically important features have to be considered. For example, urodynamic examinations or cystoscopy may trigger autonomic dysreflexia with hypertensive crises and the risk of life-threatening bradycardia.In the case of radical cystectomy, frequent adhesions and callosities of the urinary bladder, among other things, must be taken into account intraoperatively. Severe paralysis, prolonged intestinal atony and other conditions are frequently observed after the surgical procedure due to neurogenic bowel dysfunction. Correct positioning of the patient immediately after surgery to avoid decubitus and to support breathing, as well as bowel management specific to spinal cord injury, must be strictly observed.Other special features of paraplegic patients with urinary bladder cancer that should also be considered in clinical practice, as well as considerations for screening for urinary bladder tumors, are presented in the article.
