Choice of operation to promote micturition after spinal cord injury

61 male patients who had resection of the bladder neck alone, internal membranous urethrotomy alone or a combination of the 2 procedures to establish micturition after cord injury are reviewed. The combined operation has the greatest chance of initial success and should be performed if no attempt is to be made or preserve sexual function. Internal membranous urethrotomy is appropriate for lesions at all levels of the cord. Cystometry and cystourethrography are not helpful in the choice of operation.
