Abstract
A study was done on 80 male acute spinal cord injury patients with reflex bladder voiding to demonstrate an association between the development of radiological bladder trabeculation and serial urodynamic pressure/flow measurements. All patients were evaluated with cystograms and urodynamic studies during 1-3, 4-9 and 10-24 mo. after injury. Urodynamic measurements from those patients with bladder trabeculation were compared to those who retained normal-appearing bladders on X-ray. A high percentage of patients (70%) suffered trabeculation by 24 mo. after injury. Postvoid residual urine volumes were not clinically helpful in identifying those patients with bladder deterioration. Analysis of the urodynamic pressure/flow measurements revealed significant differences between patients who had trabeculation and those who maintained normal bladders on X-ray during the 3 sequential intervals after injury.
