Urinary control after radical transurethral resection of the prostate in male paraplegics: urodynamic evaluation of its effectiveness in relieving incontinence.

We report our investigation of urinary incontinence in 51 male paraplegics with radical transurethral resection of the prostate. Pre-operatively, 28 cases (55.9%) had moderate or severe incontinence, which persisted post-operatively only in 21 cases (41.2%) and was less severe. Post-operatively, bladder compliance was improved from 22.1 +/- 22.6 ml/cmH2O to 36.4 +/- 38.5 ml/cmH2O, and the maximum pressure of uninhibited detrusor contraction was reduced from 40.2 +/- 21.5 cmH2O to 18.3 +/- 19.0 cmH2O. These significant improvements are thought to contribute to the relief of urinary incontinence, regardless of the reduction in maximum urethral closure pressure.
