The asphyxiated bladder demonstrated by99mTc-D.T.P.A. renal scan

Radionuclide renal scanning is a useful aid in the assessment of the anuric or oliguric neonate. Whilst delayed micturition may be a normal physiological variation, it may be associated with a number of pathological states affecting any part of the urinary system. Four cases of the asphyxiated bladder phenomenon have been examined by^99mTc-D.T.P.A scan, showing slow renal excretion and gross bladder distension. This recently described condition should be borne in mind during the radionuclide examination of the newborn for urinary tract anomaly.
