Ultrasound diagnosis of bladder outlet obstruction in XXXX .

@entity1184 @entity95 @entity1494
One of the primary characteristics of partial outlet obstruction secondary to BPH is an increase in bladder mass commonly referred to as @entity1494 . This condition has been simulated in @entity95 by the partial ligation of the catheterized urethra. Ultrasonography has been utilized in both adult and pediatric urology to visualize the bladder and diagnose specific @entity1494 . The aim of the present study is to determine if ultrasonography can visualize bladder wall @entity1184 induced by obstruction. Partial outlet obstructions were created in NZW @entity95 using standard methodologies, and then 5 to 7 days later, sonography was performed. The films were read by both the principal investigator and blinded investigators instructed to determine bladder wall thickness and from this predict the bladder weight. Then results were correlated with cystometrograms (CMGs) and whole bladder weights. Both the principal investigator and the blinded investigators were consistently able to distinguish obstructed from control bladders based solely on sonographic depictions of relative bladder wall thickness. In addition, the investigators were able to distinguish between low (control), medium, and high bladder weights based on sonography. The accuracy of predicting the bladder weights increased when cystosonograms were correlated with CMG studies. Thus, the degree of @entity1494 can be accurately estimated by the combination of cmg and ultrasonography.
