[Participation of bladder dysfunction in urinary incontinence after prostatectomy].

Twenty-four patients with post-prostatectomy urinary incontinence were submitted to clinical and urodynamic evaluation. The clinical evaluation analyzed urinary symptoms and included rectal examination of the prostate lodge, neurourologic examination (perineal sensitivity, anal tone, bulbocavernous reflex, voluntary control of anal sphincter). The urodynamic study consisted of flowmetry, cystomanometry, detrusor pressure/micturition flow test and videocystography. An unstable bladder was demonstrated in 62.5% of the cases. Bladder dysfunction was recognized in 75% of the cases. Involvement of the striated periurethral sphincter was demonstrated in no patient. The clinical data did not provide orientation. No relation was observed between the urodynamic data, type of surgery, and amount of prostate removed. The urodynamic data appear to have a prognostic significance.
