title: Renography as a prognostic index of urinary tract problems in childhood.
abstract: Many radiological methods are used in investigating urinary tract problems in children, and some are poorly tolerated. The simplest and most acceptable technique is isotope renography. Its value has been assessed in predicting the outcome of urinary tract problems in 91 children over the age of 2 years presenting consecutively over a period of 3 months. The results of initial assessment by renography and radiography have been compared with the final clinical assessment 7 years later. 35 patients were identified as being "at risk" and all of these had abnormal renograms and radiograms. Normal renographys was found unexpectedly in some patients with severe reflux but with a good final result. It is concluded that renography can be used to screen children with urinary tract infection, thereby excluding the less acceptable radiological investigations unless the renogram is abnormal.
