Intermittent catheterization failure and an approach to bladder rehabilitation in spinal cord injury patients.

Forty-six patients with spinal injury with dysfunctional neurogenic bladder were analyzed. Fourteen patients on prolonged intermittent catheterization from 12 weeks to more than 1 year did not develop a balanced bladder, 14 patients had indwelling catheters after intermittent catheterization failed elsewhere and 18 patients on external condom drainage presented with difficult voiding and repeated infections. There were 16 quadriplegics (1 incomplete), 21 paraplegics, and 9 incomplete cauda equina lesions. Urologic and urodynamic evaluation revealed detrusor-sphincter dyssynergia in 15 patients, vesicoureteral reflux in 10, and areflexic bladders in 11. Five patients over the age of 55 years showed slight enlargement of the prostrate. Some degree of bladder neck fibrosis was suspected in 26. More than one urologic pathology was encountered in the same patient. Transurethral sphincterotomy was carried out in 38 patients and only one transurethral resection of the prostrate (TURP) in an incomplete quadriplegic patient. In seven patients with no obvious urodynamic abnormality, a balanced bladder was achieved with intermittent catheterization; however, one of these patients needed a transurethral sphincterotomy on subsequent admission. A balanced bladder was achieved in all patients except the one with incomplete quadriplegia. Significant improvement in vesicoureteral reflux and relief from autonomic dysreflexic symptoms were recorded in all patients.
