Urodynamic responses to anal stretch in patients with detrusor sphincter dyssynergia.
OBJECTIVE
To evaluate the urodynamic responses to anal stretch in patients with detrusor sphincter dyssynergia (DSD).


METHODS
Descriptive study.


METHODS
Rehabilitation hospital affiliated with a medical university.


METHODS
Patients (N=36) with suprasacral spinal cord injury who had DSD confirmed on cystometrography.


METHODS
Not applicable.


METHODS
Detrusor pressure, urethral pressure, and summated electromyogram of external urethral sphincter on cystometrography.


RESULTS
The urodynamic responses to anal stretch were evaluated in the first half (time 1, 1-15s) and the second half (time 2, 16-30s) of the evaluation time period. The activity of external urethral sphincter was reduced significantly in both times 1 and 2 (P<0.5). The medians of reduction percentages were 33% and 35% for times 1 and 2, respectively. The change of detrusor pressure was not significant in either time 1 or time 2.


CONCLUSIONS
Anal stretch can reduce the activity of external urethral sphincter without significant change in detrusor pressure.
