Urodynamics in enuretic children

Although the incidence of an organic cause is low and most of the detected genitourinary anomalies are not responsible for enuresis, a simple, noninvasive screening test is preferable in the analysis of children with enuresis. Extension of standard radionuclide renography as a method of screening the upper as well as lower urinary tract function in one session is noninvasive and at least as good as conventional direct urine flow rate recording. This method was carried out in 124 children. In 30%, some abnormality probably related to the enuresis was identified. Upper urinary tract anomalies were identified in 5% of the children, anomalies of the upper and the lower urinary tract in 9.6%, and functional voiding disturbances in 16%.
