Pelviureteric obstruction in children: growth of kidney parenchymal area after pyeloplasty.

The excretory urographies of 26 patients with unilateral pelviureteric obstruction were analysed retrospectively. All patients had had dismembered pyeloplasty performed at the age of 9 months to 15 years 2 months. Planimetric parenchymal area measurements of each kidney were made from urographies performed preoperatively and at different stages of the follow-up period, the latest follow-ups being effected 3 to 14 years postoperatively.

Pelviureteric obstruction in children: the effect of pyeloplasty on 99mTc-DTPA uptake and washout.

The renographies of 23 children, treated by means of dismembered pyeloplasty for unilateral pelviureteric obstruction, were analysed. Computerised 99mTc-DTPA renography was performed on each patient both preoperatively and on one or several occasions postoperatively. Of the 13 hydronephrotic kidneys, which had normal glomerular function preoperatively, 12 had also normal postoperative function.

Pelviureteric obstruction in children: kidney parenchymal area and technetium-99m diethylenetriaminepentaacetic acid renography.

In 33 patients with pelviureteric obstruction the renal parenchymal area was measured from excretory urography films and split renal function determined with computerized 99mTc-DTPA-renography. All patients had pelviureteroplasty performed during childhood. For this study, excretory urographs and DTPA-renographs performed in 7 patients preoperatively and in all the 33 patients 10 months to 15 years postoperatively, were analyzed.

Pelviureteric obstruction in children.

A series of 161 hydronephrotic kidneys from a 30-year period in 147 children is reported. The left kidney was affected more frequently than the right and the condition was more common in the male than in the female child. In infants, abdominal mass was a common mode of presentation.
