Abstract
1. Ten patients with neurological evidence of damage to the intrathecal sacral nerve roots of the cauda equina by verified lumbar disc prolapse are described.
2. The nature of the bladder paralysis has been investigated by cystometry and the findings contrasted with published opinions.
3. The prognosis of the bladder paralysis has been established by review up to six years after removal of the disc prolapse. No evidence of recovery of complete bladder paralysis has been found, but the consequences of persistent bladder paralysis have been much less severe than previous reports have stated. Reasons have been suggested for this.
4. Principles of recognition and management of bladder paralysis due to cauda equina lesions have been stated and methods suggested.
