OUTCOMES OF EARLY PYELOPLASTY IN INFANTS WITH URETEROPELVIC JUNCTION OBSTRUCTION GRADE 3-4 SFU: MORPHOLOGICAL AND FUNCTIONAL PROSPECTIVE.

Abstract

Congenital ureteropelvic junction obstruction is considered one of the common causes of prenatally
diagnosed hydronephrosis , which if left untreated , it can lead to progressive renal impairment [1]
.UPJ obstruction is
one of the most common causes of antenatally detected hydronephrosis, with an estimated ultrasonographic
incidence of fetal upper urinary tract dilatation in approximately 1 in 100 pregnancies; however, only 1 in 500 are
later diagnosed with significant urologic problems, PUJ obstruction is found in approximately 50 % of patients
diagnosed with antenatal hydronephrosis.
