[Familial vesicoureteral reflux].
Primary vesicoureteral reflux was seen in 2 siblings in a family of 5 (1 daughter and 2 sons). Voiding cystogram of elder sister, who complained of fever and backache, showed bilateral reflux at the age of 6. Left reflux disappeared soon but right reflux persisted. Right antireflux operation was performed at the age of 9, but right renal function deteriorated gradually. Right nephrectomy was done at the age of 12 because of persistent pyuria and renal stones. The second case was her younger brother who was sent to us because of proteinuria and hypertension. Excretory urogram showed left small kidney and voiding cystogram showed bilateral reflux with moderately dilated ureter and calyceal blunting. Urinalysis revealed normal findings except for proteinuria and he had no urological symptoms. Renal angiogram and renal vein renin study were unremarkable, so bilateral antireflux operation was done. Findings of urinalysis of his parents and younger brother were normal and cystogram of his brother was normal.
