A finger device for obtaining satisfactory voiding in spinal cord-injured patients

Anal sphincter stretch is a technique or procedure that recently has been found effective in overcoming the problem of ineffective voiding caused by detrusor-sphincter dyssynergia in some cases and for patients with upper motor neuron lesions. This technique was made available to quadriplegic patients when a fabricated device worn over the patient's finger was used. Four C7 quadriplegics have been able to achieve consistently acceptable amounts and residual volumes when voiding.

Sphincter stretch: a new technique resulting in continence and complete voiding in paraplegics

A technique is described to facilitate voiding in the paraplegic, whereby external sphincter spasm is eliminated as a source of obstruction. Digital stretch on the anal sphincter combined with the Valsalva maneuver has resulted in satisfactory bladder emptying in 16 paraplegic patients. The technique has been found unsatisfactory in patients with contracted bladders or with incomplete lesions of the spinal cord.
