Management of XXXX .

@entity1 @entity384 @entity177 @entity354 @entity340
A series of 46 @entity1 treated by the author since January 1972 for @entity340 is presented: 22% were diagnosed at birth, 28% as neonates and 52% in the first 3 months of life. Ninety-three per cent had unilateral or bilateral dilatation of the upper urinary tract at the time the valves were diagnosed and 72% had ureteric reflux. Unilateral reflux occurred into the left ureter twice as often as the right. @entity177 was present at the time of diagnosis in 72% of all of the @entity1 but in 83% of those aged less than 3 months. Surface urinary diversion was used minimally during post-operative management and contributed little to the recovery of renal function. @entity354 disappeared spontaneously in one-third of the refluxing ureters. @entity384 subsided spontaneously in 57% of dilated ureters. Surgery was performed mostly for reflux. Non-refluxing ureteric dilatation was made worse by surgery in a few instances and in others the dilatation improved with time rather than as a result of surgery. Renal function returned to normal in over 60% of the @entity1 who were in @entity177 at diagnosis. Measurement of glomerular filtration rate was the most accurate method of predicting recovery of renal function: a value of less than 50% of normal for age at the time of diagnosis forecast persistent @entity177 with all its attendant complications.
