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.
