Epidemiological Features of the Bladder Neck Rest Position and Mobility

Area of Science:

• Urogynecology
• Pelvic Floor Disorders
• Female Urology

Background:

• Epidemiological data on bladder neck (BN) mobility determinants are limited.
• Understanding factors affecting BN position is crucial for managing pelvic floor disorders.

Purpose of the Study:

• To identify epidemiological factors influencing resting bladder neck (BN) position.
• To determine factors affecting bladder neck (BN) mobility in women without pelvic organ prolapse (POP).

Main Methods:

• Pelvic floor ultrasound was used to measure BN position and mobility.
• Demographic and functional factors were assessed in 796 patients.

Main Results:

• Vaginal deliveries (VDs) and age (≥65) correlated with lower resting BN position.
• Stress urinary incontinence (SUI) was associated with higher BN mobility.
• Obesity showed a higher resting BN position and lower BN mobility, linked to longer urethras.
• VDs increased BN mobility independently of body mass index (BMI).

Conclusions:

• Obesity, VDs, and age significantly impact resting BN position and mobility.
• Increased BMI is linked to restricted BN mobility, suggesting SUI in obese patients may not be due to hypermobility.
