High incidence of vesicoureteric reflux in asymptomatic siblings of children with known reflux
A significant occurrence of vesicoureteric reflux in siblings of children with reflux has been previously suggested. The purpose of this study was to evaluate the incidence of vesicoureteric reflux in asymptomatic siblings of children with vesicoureteric reflux using radionuclide voiding cystography (RNC). A random group of 52 siblings was studied. Their ages were from 2 mos. to 13 yrs. (mean 4 yrs.). Seventy-one percent were female and 29% male, RNC was performed with the patients supine, and Tc-99m pertechnetate (2mCi/1) was infused into the bladder by catheter. A computerized gamma camera recorded the filling and voiding phase of the study at 1 frame/5 sec. Reflux was detected in 40% of the patients. It was bilateral in 17% and unilateral in 23% of the patients. Reflux was identified to the renal pelves in half of the patients. In two of these patients Tc-99m DMSA scans were obtained which revealed significant renal scarring. This study demonstrates the high incidence of reflux of various degrees in these asymptomatic siblings on high risk of developing significant renal disease. Identification and proper treatment of asymptomatic children with vesicoureteric reflux may help prevent the development of renal damage.
