THE DIAGNOSIS OF BLADDER OUTLET OBSTRUCTION IN MEN BY ULTRASOUND MEASUREMENT OF BLADDER WALL THICKNESS

AbstractPurpose: The objective of the study was to investigate specificity and sensitivity of bladder wall thickness in the diagnosis of bladder outlet obstruction.Materials and Methods: The study included 174 patients referred to our prostate centers for lower urinary tract symptoms. Free uroflowmetry and pressure-flow studies were performed in duplicate as part of the diagnostic evaluation. After the 2 voiding studies were done the bladder was filled to 150 ml. and wall thickness was measured via suprapubic ultrasound. Bladder outlet obstruction was diagnosed and graded according to the Abrams-Griffiths and Schafer nomogram as well as to the group specific urethral resistance algorithm.Results: A significant correlation (r>0.6, p bladder outlet obstruction, since 63.3% of patients with bladder wall thickness less than 5 ...
