Radiological trabeculation for the male bladder--a clinical and urodynamic assessment

Area of Science:

• Urology
• Nephrology
• Radiology

Background:

• Radiological trabeculation is a common finding in urological imaging.
• Its relationship with urodynamic findings, particularly detrusor instability and outflow obstruction, requires clarification.

Purpose of the Study:

• To investigate the association between radiological trabeculation and urodynamic findings in 250 patients.
• To differentiate the causes of trabeculation based on urodynamic parameters.

Main Methods:

• Synchronous cine/pressure/flow cystometry was performed on 250 patients.
• Radiological findings were correlated with urodynamic measurements.

Main Results:

• A strong association was observed between detrusor instability and trabeculation.
• Trabeculation can also occur with high-pressure outflow obstruction (often prostate-related) without detrusor instability.
• Frequent, involuntary detrusor contractions against a closed sphincter may cause prominent trabeculation.

Conclusions:

• Trabeculation is strongly linked to detrusor instability.
• The presence of trabeculation alone, especially minor degrees, does not definitively confirm detrusor instability.
• High-pressure outflow obstruction should be considered in cases of trabeculation without documented instability.
