RISK-FACTORS FOR BLADDER-TUMORS IN SPINAL-CORD INJURY PATIENTS

Purpose: We evaluated risk factors for the development of bladder tumo rs in spinal cord injury patients. Materials and Methods: A retrospect ive review was done of all bladder tumors at 1 institution with matche d controls for 7 years. Results: We identified 17 malignant and 2 beni gn tumors. Indwelling bladder catheters and a history of bladder stone s were statistically significant risk factors. Four patients with nega tive biopsies underwent repeat biopsy due to suspicious cytology and c ancer was found. Conclusions: An indwelling urinary catheter and a his tory of bladder stones are statistically significant risk factors. Cyt ology and biopsy are complementary in the evaluation of urothelial mal ignancy in this population. A high index of suspicion and thorough eva luation are needed in spinal cord injury patients.
