Radiologic method to assess urinary bladder capacity and proportions in children.
The bladder capacity has been determined physiologically and radiologically at micturition urethrocystography in 139 otherwise normal children 4 to 8 weeks after a bacteriologically confirmed, successfully treated urinary tract infection. This capacity, at a pressure of 50 cm of contrast medium, has been correlated to the length of the lumbar segment L1 to L3. The assessment of normal and abnormal bladder size can be made from infused volume or three dimensional radiologic measurements and is expressed in standard deviations.
