Is ultrasound estimation of bladder weight a useful tool in the assessment of patients with lower urinary tract symptoms?

Introduction and hypothesis The aim of this study was to assess the relationship between ultrasound estimation of bladder weight (UEBW), symptoms and urodynamic diagnosis. Methods Women with lower urinary tract symptoms underwent urodynamics studies and measurement of UEBW at a fixed bladder volume.
