Risk factors for bladder tumors in spinal cord injury patients.

Abstract

We evaluated risk factors for the development of bladder tumors in spinal cord injury patients. A retrospective review was done of all bladder tumors at 1 institution with matched controls for 7 years. We identified 17 malignant and 2 benign tumors. Indwelling bladder catheters and a history of bladder stones were statistically significant risk factors. Four patients with negative biopsies underwent repeat biopsy due to suspicious cytology and cancer was found. An indwelling urinary catheter and a history of bladder stones are statistically significant risk factors. Cytology and biopsy are complimentary in the evaluation of urothelial malignancy in this population. A high index of suspicion and thorough evaluation are needed in spinal cord injury patients.
