Urodynamic evaluation revealed that many women with bladder instability require specific tests to diagnose their condition. Provocative or erect testing is often necessary to confirm bladder instability.

Area of Science:

Urology
Gynecology

Background:

Vesical instability is a common condition affecting women.
Accurate urodynamic evaluation is crucial for diagnosis and treatment.

Purpose of the Study:

To assess the diagnostic yield of different urodynamic methods for detecting vesical instability in women.
To identify the prevalence of combined genuine stress incontinence and vesical instability.

Main Methods:

Thirty-two women with suspected vesical instability underwent urodynamic evaluation.
Methods included dynamic urethral profilometry, supine cystometry, and provocative/erect cystometry.

Main Results:

Combined incontinence was diagnosed in 41% of patients.
Supine cystometry at rest identified vesical instability in 66% of patients.

Provocative maneuvers or erect cystometry were needed for diagnosis in 34% of patients.

Urethral instability preceded detrusor contractions in 22% of patients.

Conclusions:

Standard supine cystometry may underestimate the prevalence of vesical instability.
Specific provocative maneuvers or erect cystometry enhance diagnostic accuracy for bladder instability.
Urethral instability can be a precursor to detrusor overactivity.
