Abstract
Urine cultures were obtained by percutaneous aspiration of renal pelvic urine in an attempt to localize the source of chronic asymptomatic bacteriuria in 10 patients with intestinal segments incorporated into the urinary tract. One child with a nonrefluxing colonic conduit and 6 of 8 patients with nonrefluxing enterocystoplasties had upper tract bacteriuria. One patient with a ureterosigmoidostomy and a history of pyelonephritis had negative cultures while on prophylactic antibacterials. The significance of upper tract bacteriuria in these patients is unknown but lifelong followup of renal function is necessary.
