Overview
Brief Summary
To study the predictive value of ultrasonographic (USG) parameters in the form of anteroposterior diameter , calyceal dilatation , calyx-to-parenchyma ratio , renal length , renal width , pelvis-to-cortex ratio (PCR) and parenchymal thickness versus renographic parameters in the form of T1/2 , differential renal function (DRF) and Tissue tracer transit (TTT) for early detection of children at risk of recurrent obstruction post unilateral pyeloplasty.

Outcomes
Primary Outcomes
evaluate predictive value of ultrasonographic parameters for early detection of decrease renal function
Time Frame: 30 months
assessed by Diuretic scintigraphy differential renal function (DRF) measured in millilitres/minute
evaluate predictive value of ultrasonographic parameters for early detection of recurrent obstruction
Time Frame: 30 months
assessed by Diuretic scintigraphy (T1/2) as the time it takes for the activity in the kidney to decrease to 50% of its maximum value measured in minutes
