International system of radiographic grading of vesicoureteric reflux. International Reflux Study in Children.

The classification of grading of vesicoureteric reflux (VUR) agreed to by the participants in the International Reflux Study in Children is described. It combines two earlier classifications and is based upon the extent of filling and dilatation by VUR of the ureter, the renal pelvis and the calyces. A standardised technique of voiding cystography is also described to ensure comparability of results.

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.

Epidermolysis bullosa dystrophica with urinary tract involvement.

A case of epidermolysis bullosa dystrophica ( EBD ), neonatally corrected atresia of the pylorus and early infantile development of urinary tract manifestations is reported. Owing to misinterpretation of radiological findings, instrumental treatment of the urethra was employed. It resulted in complete and permanent obliteration of the lumen.

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.
