Urodynamic detrusor overactivity in patients with overactive bladder symptoms

Area of Science:

• Urology
• Urodynamics
• Female Pelvic Medicine

Background:

• Overactive bladder (OAB) is a common condition characterized by urinary urgency, often with frequency and nocturia.
• Urodynamic detrusor overactivity (DO) is a key finding in OAB diagnosis, but its correlation with OAB symptoms requires further investigation.

Purpose of the Study:

• To evaluate the relationship between urodynamic detrusor overactivity (DO) and overactive bladder (OAB) symptoms in adult men and women.
• To determine if symptom combinations improve the prediction of DO in OAB patients.

Main Methods:

• Retrospective review of adult male and female patients undergoing urodynamic evaluation for OAB symptoms.
• DO assessment based on symptoms alone or in combination with urodynamic findings.

Main Results:

• Overall DO incidence was 76.1% in men and 58.7% in women with OAB.
• Patients with urgency and incontinence (OAB wet) showed higher DO rates (93% men, 69.8% women) compared to those with urgency only (OAB dry) (63% men, 61% women).
• Combination of symptoms, particularly urge urinary incontinence (UUI) and urgency in men, and UUI and nocturia in women, showed better correlation with DO.

Conclusions:

• A stronger correlation exists between OAB symptoms and urodynamic DO in men compared to women, particularly in OAB wet cases.
• Combining OAB symptoms appears to be a more accurate predictor of DO, correlating better with objective urodynamic parameters.
