The quantitative nuclear cystogram: an aid in determining the spontaneous resolution of vesicoureteral reflux.

Abstract

The quantitative data derived from serial nuclear cystograms during a 5-year period in 39 children were compared to the clinical course. A direct correlation (93 per cent) between an increasing bladder volume at which reflux occurs was observed in the clinically stable group. In the clinically unstable group there was a 77 per cent correlation of an unchanged or decreasing bladder volume at which reflux occurs. The quantitative nuclear cystogram provides an objective as opposed to subjective data base for management of patients with vesicoureteral reflux.
