Voiding by increased abdominal pressure in male spinal cord injury patients--long term follow up.

We reviewed the long term follow up of five spinal cord injury patients with detrusor areflexia who emptied their bladder using high abdominal pressure. Ages ranged from 29 to 58 years, and the mean time elapsed from injury was 18.9 years. The bladder pressure during voiding ranged from 95 to 160 cm of water. One patient developed vesicoureteral reflux and hydronephrosis. Long term monitoring is suggested in patients who use high abdominal pressure for bladder emptying.
