Primary vesicoureteral reflux: progress of disease, somatic growth and renal parameters.

ABSTRACT

Thirty children (45 units) in the age group 1 day-12 yrs with primary vesicoureteral reflux were studied prospectively and periodically assessed for renal function, scarring, grade of reflux and somatic growth parameters. Four children (6 units) with grade IV reflux underwent ureteric reimplantation. Complete resolution with medical management was seen in all 12 units of grade I-III reflux and in 5 of the remaining 27 units of grade IV-V reflux over 6 months-6 yrs. This group showed highly significant improvement in height . The weight gain of the above 2 groups was statistically significant compared to those with persistent reflux. Focal defects were seen initially in 62 percent refluxing units. None of the patients showed deterioration in renal function or formation of new scars over the next 1-7 years. Three children on conservative management showed persistent growth retardation with associated breakthrough infection, hypertension, multiple renal scars and poor renal functional volume.
