Objectives:
To examine the relationship between voiding symptoms and objective measurements of voiding dysfunction.
Methods:
We prospectively collected data from 116 consecutive women attending for urodynamic investigations. Symptoms of voiding dysfunction and objective voiding parameters including uroflowmetry and post-void residual volume were evaluated.
Results:
Sixteen (14%) patients reported a symptom of straining, 21 (18%) double voiding, 32 (27%) post-micturition dribbling, 10 (8%) poor stream and 34 (29%) incomplete emptying. Using receiver-operator curves we were unable to determine a cut-off value for flow or residual volume where symptoms became more prevalent. Poor stream was, however, a good predictor for a residual volume of >100 mL and >150 mL. Strain predicted a residual volume of >100 and >150 mL and it correlated with maximum flow rate <15 mL/s. The other three symptoms did not correlate with any of the cut-off values.
Conclusions:
Poor steam and strain are weakly predictive of abnormal voiding function.

Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

01:26The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
