title: Urine extravasation secondary to upper urinary tract obstruction.
abstract: To the best of our knowledge, this is the first reported case of renal salvage in a neonate with presumed spontaneous perirenal leakage of urine associated with ureteropelvic junction obstruction. Many instances of such extravasation in this age group have been described with lower urinary tract obstructions. As in the latter cases, the occurrence of extravasation secondary to upper tract obstruction need not preclude primary reconstruction.
