Bladder function following spinal cord injury: a urodynamic analysis of the outcome.

Repeated urodynamic testing was undertaken on a group of 58 consecutive patients admitted with acute spinal cord injury. Thirty-seven (64%) were able to void satisfactorily spontaneously, whereas 10 required bladder outlet surgery and 11 achieved emptying by either abdominal straining, intermittent self-catheterisation or an indwelling suprapubic catheter. The pattern of the initial cystometry soon after injury provided some idea of what possibilities could be expected of subsequent bladder function. Very high detrusor pressures exceeding 80 to 100 cm of water developed in a third of patients with supranuclear lesions. Six patients developed vesicoureteric reflux between 4 and 24 months after injury.
