Introduction And Hypothesis:
When incontinence accompanies detrusor overactivity (DO), the pressure at which it occurs may have important predictive value and should be termed DO leak point pressure (DOLPP).
Methods:
A retrospective review of our video urodynamics database (n = 222) including validated questionnaires was performed. DOLPP was defined as detrusor pressure the moment DO incontinence occurred. Statistical analysis was performed using Student's t-test.
Results:
Women with DO leakage (47) and with DO without leakage (15) were analyzed. Urgency and urgency incontinence (UUI) were greater among patients with DO leakage. A link between sphincter deficiency and greater severity of UUI was noted. Among patients with DO leakage, those with subjective mixed incontinence had a lower mean DOLPP than those with pure UUI (p = 0.004). The detrusor pressure at peak flow was lower in the DO leakage group (versus DO alone, p = 0.05) likely reflecting a measure of outlet resistance.
Conclusion:
DOLPP has predictive meaning in women and should be further studied for possible inclusion in standard urodynamic terminology.

The 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...

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Urethra
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...
