From 1979 to 1989, 269 patients with spinal cord injury were managed by an aseptic intermittent catheterization program during the acute phase of their injuries at the Spinal Injuries Center. One hundred fifty one patients with incomplete cord lesion and 36 males with complete tetraplegia were managed by program I, which protects the shocked bladder from overdistension. In contrast, 82 patients with complete cord lesion excluding male tetraplegia were managed by program II, which allows

... ension of the bladder. Of the 187 patients managed by program I, 137 (73.3%) achieved trigger voiding function, 61.3% of whom were completely dry. Of the 82 patients managed by program II, 62 (75.6%) were put to self-or assisted catheterization, 67.7% of whom were dry. The incidence of a grade I, which means normal bladder configulation, was 88.0% for program I and 87.3% for program II during the follow up course. Upper urinary tract deterioration occurred in only one case. Surgical treatment for urinary tract complications was performed in 14 cases (5.2%). These results suggest that the patients with incomplete cord lesion managed by non-distension regimen of the bladder (program I) and those, especially female, with complete cord lesion managed by overdistension regimen of the bladder (program II) achieve urinary continence with excellent urinary prognosis.
