Abstract

The vesicoureteral reflux, the regurgitation of urine after it has entered the bladder back into the ureter, has been a topic of intense interest and speculation for recent years. It has been generally accepted that in certain pathologic or anomalous conditions, such as obstruction or stenosis of neck of urinary bladder, certain paralytic diseases and spina bifida or meningomyelocele etc., the vesicoureteral reflux occurs quite frequently, in more than 13%, and that the process should be eliminated because it will inevitably lead to impairment of renal function and ultimate total renal destruction.
In Spite of this fact, a direct positive approach to correction of the problem is often tempered by conflicting opinions about whether the reflux may occur in normal individual. The question as to whether the vesicoureteral reflux does or does not occur in the normal urological tract has recieved considerable attention and Aiscussion in the past years but no definite proof has been offered on either side of question.
This investigation was undertaken in an effort to find out whether vesicoureteral reflux did or did not take place in the apparently normal childs urological tracts. The author performed delayed cystogrophy and voiding cystography in 200 of normal Korean children, 100 of male and 100 of female, aged from 4 months to 12 years who were judged to have normal urinary tract by history, physical examination and laboratory tests.
The results were as follows:
1. Vesicoureteral reflux may occur in children who have apparently normal urological tracts.
2. The incidence of vesicoureteral reflux was 3% (6 of 200 children).
3. The sex distribution of vesicoureteral reflux was equal (3 males and 3 females).
4. The age distribution, of vesicoureteral reflux was even throughout the examined: 1 of each 12, 11, 8, 3, and 1 yrs. of age.
5. The site distribution of vesicoureteral reflux was 1 on the right, 2 on the left and 3 on bilateral.
6. The findings of the intravenous pyelograms revealed mild calyceal blunting in 2 of 6 children (33%) but the rest showed normal appearance.
7. The findings of the cystograms revealed slight ureterectasis and hydronephrotic changes in 2 of 6 children (33%) but rest showed normal appearance.
8. Among 6 children who revealed vesicoureteral reflux, 3 children were brethren of 5 siblings, and they were 1st, 2nd and 3rd bornes.
