Can Bladder Wall Thickness Measurement Be Used for Detecting Bladder Outlet Obstruction?

Area of Science:

• Urology
• Medical Imaging
• Prostate Health

Background:

• Lower urinary tract symptoms (LUTS) are common in men with benign prostatic enlargement.
• Assessing bladder outlet obstruction (BOO) is crucial for managing LUTS.
• Current diagnostic methods can be invasive or time-consuming.

Purpose of the Study:

• To evaluate the association between bladder wall thickness (BWT) and uroflowmetry parameters.
• To determine the relationship between BWT and the International Prostate Symptoms Score (IPSS).
• To explore BWT as a predictor of BOO severity in patients with LUTS.

Main Methods:

• 236 male patients with LUTS due to benign prostatic enlargement were included.
• Bladder wall thickness (BWT) was measured using suprapubic ultrasonography.
• Uroflowmetry, postvoid residual (PVR) volume, and IPSS were assessed to identify BOO indicators.

Main Results:

• A positive correlation was observed between BWT and IPSS, PVR, and LUTS duration.
• A negative correlation was found between BWT and maximum flow rate (Qmax).
• BWT significantly increased with a higher number of BOO indicators present.

Conclusions:

• Bladder wall thickness (BWT) is a valuable, non-invasive parameter for assessing BOO severity.
• BWT measurement is a simple, rapid, and reproducible test.
• BWT can aid in predicting and managing BOO in patients with LUTS.
