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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| evaluate predictive value of ultrasonographic parameters for early detection of recurrent obstruction | 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 |
| evaluate predictive value of ultrasonographic parameters for early detection of decrease renal function | 30 months | assessed by Diuretic scintigraphy differential renal function (DRF) measured in millilitres/minute |
