title: Ureteropelvic junction obstruction: the effect of pyeloplasty on renal function.
abstract: We studied preoperatively and postoperatively 41 children who underwent pyeloplasty for correction of unilateral ureteropelvic junction obstruction. Conventional radiological studies and quantitative radioiodine hippurate renal scans were obtained to assess the effect of pyeloplasty on the appearance of the kidney and its function. Analysis of the data suggests that the degree of improvement in renal function is related primarily to the age at which the surgical correction is accomplished and whether infection has occurred preoperatively.
