Purpose:
To evaluate the urodynamic characteristics of a series of women with stress urinary incontinence presenting various rates of vaginal prolapse.
Methods:
92 female patients were included in this study, mean age was 48 years (range 29-75). All patients underwent urogynecologic physical examination (vaginal prolapse was graded) and complete urodynamic study in order to detect the presence of detrusor overactivity. Urodynamic terminology and measurements comply with the ICS (International Continence Society) standards. Statistical significance was established below 0.05.
Results:
65 women (70.6%) presented anterior vaginal prolapse and 31 (33.6%) posterior vaginal prolapse. Involuntary contractions of the detrusor muscle appeared in 13 patients (20%) who had an anterior vaginal prolapse and 6 women (19.3%) who had a posterior vaginal prolapse. The existence of involuntary contractions was not associated with the diagnosis of vaginal prolapse.
Conclusion:
Our study did not show any correlation between existence of vaginal prolapse and detrusor overactivity.

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...

Disorders of the Urinary System
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...
