title: [Diuresis renography in the postoperative course of pyeloureteral stenosis].
abstract: Ureteropelvic junction (UPJ) obstruction constitutes the most common form of upper urinary tract obstruction in children. We study the role of diuretic renography and its correlation with other diagnostic methods for postoperative evaluation of this malformation. We reviewed 13 patients, 10 males and 3 females aged 1 months to 15 years, and with right UPJ obstruction in six and left obstruction in seven. In all of them pre and postoperative IVP, abdominal ultrasound, diuretic renography, and pressure flow studies. Were performed our results demonstrated a non-correlation between the findings of excretory urogram, abdominal ultrasound and diuretic renography and a close relation between pressure flow studies and diuretic nephrography. This two last methods are good tools for assessment of UPJ obstruction.
