title: Utility of bladder lavage in Meckel's scanning.
abstract: Accumulation of radioactive urine in a bladder diverticulum on a Tc-99m pertechnetate scan simulated uptake in a Meckel's diverticulum. The abnormal activity was present even following bladder catheterization and drainage. However, saline lavage washed the residual activity out of the bladder, and prevented a false-positive diagnosis. In addition to preventing false-positive studies, bladder lavage may increase the sensitivity of the test by allowing the detection of Meckel's diverticuli that are obscured by residual bladder activity.
