[Comparison between autonomic nervous system cardiovascular tests (ANSCVT) and lacrymal and or salivary secretion...

To compare autonomic nervous system cardiovascular tests (ANSCVT) and lacrymal and or salivary secretion tests (LSST).

One hundred and twenty-four patients (57 females, 67 males, mean age 45) with lower urinary tract symptoms (overactive bladder syndrome or voiding dysfunction) without neurogenic or urological causes, were included. Urodynamic was performed in all the patients with LSST (saliva flowmetry-sialometry [SFS], candy weight-loss test [CWT], Schirmer test [SchT]) and ANSCVT (ratio 30:15, orthostatic hypotension analysis, deep breath test [DBT], Valsalva maneuver [VM], cold pressor test [CPT] and hand grip test [HGT]).

In eight cases, ANSCVT were altered (four in OAB syndrome, four in voiding dysfunction). No correlation was found between positive ANSCVT and LSST (P=0.72 for CWT, P=1 for SFS, P=0.1 for SchT). In contrary, there is a significant correlation between SchT and CWT (P=0.049), but not between SchT and SFS (P=0.69) or SFS vs CWT (P=0.06).

In this series LSST were not sufficient to track down autonomic nervous system alterations and ANSCVT always necessary. Autonomic dysfunctions were infrequent in OAB syndrome and "idiopathic" voiding dysfunctions (6.5%).
