Diagnostic Potential of Imaging Modalities in the Assessment of Lower Urinary Tract Dysfunctions

Lower urinary tract dysfunction (LUTD) is common in both men and women, and the incidence and prevalence increases as people age. Commonly observed symptoms of LUTD include nocturia, urgency, urinary incontinence and frequency of voiding. Recognizing the key role accurate monitoring and evaluation of LUTD play in the day-to-day assessment of the condition, this chapter will explore the diagnostic capabilities of imaging modalities including MRI, ultrasound and fluoroscopy in assessing bladder wall thickness (BWT), detrusor wall thickness (DWT) and estimation of bladder weight both in real-time and static positions, and finally analyze their suitability as surrogates for bladder outlet obstruction (BOO) or detrusor overactivity (DO)
