Radiological consideration of neurogenic bladder in patients with traumatic spinal injury

We evaluated 104 patients of neurogenic bladder secondary to traumatic spinal cord injury. Those were diagnosed by I. V. P. and V. C. U. at Korea Veterans Hospital during 9 years from January, 1978 to May, 1987. The type of neurogenic bladder, complications and urethral configuration, according to the level of spinal cord injury were discusses. The result were as follows: 1. The incidence of patient according to the level of spinal cord injury was 49 out of 104 in those with vertebral level T7 or above, 15 out of 104 in those with T8-T10 level, and 40 in those with vertebral level T11 or below. The incidence of UMNB was 67.3% in those with vertebral T7 or above, 53.3% in T8-T10. The incidence of LMNB was 62.5% in those with vertebral level T11 or below. 2. Overall incidence of urinary tract calculus was 32.7%. Highest incidence of calculus was 46.7% in those with vertebral level T8-T10. 3. Overall incidence of vesicoureteral reflux was 23.1%. Highest incidence of reflux was 46.7% in those with vertebral level T11 or below. 4. Overall incidence of pyelonephritis was 26.9%. 5. Overall incidence of hydronephrosis was 20.2%. Highest incidence of hydronephrosis was 27.5% in those with vertebral level T11 or below. 6. Almost entire urethra was shown funnel type in 66 out of 73 cases. Saccular dilatation of posterior urethra was 7 cases. Saccular dilatation of posterior urethra with LMNB was 4 cases, which were occurred only in those with vertebral level T11 or below
