THURSDAY, Feb. 15 (HealthDay News) -- When gross hematuria occurs in pediatric patients, it's more likely to occur in boys than girls and it's usually due to benign causes, according to a clinical review published in the January issue of Urology.
Saul P. Greenfield, M.D., of the Women and Children's Hospital of Buffalo, N.Y, and colleagues reviewed charts from 342 of their patients who presented with gross hematuria over a 10-year period between 1994 to 2003.
Eighty percent of the cases were boys. The underlying causes ranged from benign urethrorrhagia (19 percent), trauma (14 percent), and urinary tract infection (14 percent). Overall, 13 percent of the total patient population had congenital urologic anomalies including vesicoureteral reflux, posterior urethral valves, ureteropelvic junction obstruction, hypospadias, ureterovesical junction obstruction, ureterocele, and caliceal diverticulum.
"Voiding cystourethrography is useful in those with suspicious ultrasound findings, urinary tract infection, or voiding symptoms," the authors write. "Cystoscopy should be reserved for the minority in whom hematuria persists or those with ambiguous imaging study findings."
