And also, I mean, I will tell the healthy kidneys of the EJS group. And thus, the ultimate avatar again is the sensitivity, specificity of the R.I. in obstructive, sensitivity, specificity, positive and negative rate equivalent of R.I. in the obstructive hydrodynamic process. So, this is the general cost of the study. The study proportion is 64 children and we have done all for 1.5 years. The inclusion criteria we have to take below two LBs of age who are referred for ultrasound for renal system anomalies and also found to have hydrodynamic process. The children of the same age with healthy kidneys also referred for ultrasound or the system other than renal system also included in the study for control. And we exclude the children who have a lethal abnormalities or critically ill children. Also, the children with kidney disease other than hydrodynamic disease like the medical renal disease which can cause also the spurious rise of the R.I. and the kidney results who have equivocal inconclusive result on the DTPS care. And we also exclude those patients whose parents did not consent for ultrasound evaluation. We use due to measure, we use Philly 87 LBP in equivate both machines because one machine was non-functional in the immediate situation. We also created a pro forma for recording the clinical history and also other investigational findings. And then we do the ultrasound first followed by Doppler assessment and the Doppler R.I. value was taken at the high level. And the ultrasound was really non-serivative and without sedation or breath hold. The R.I. was also noted but also calculated by this formula by PSV minus EGV by PSV value and the obstructive non-strativative VTBA findings And the measured R.I. value was tabulated. The R.I. value greater than .7 was very high and the R.I. value of .7 was very low and also do the statistical analysis by the software and the PV value less than 0.05 were considered statistically significant. So the RE-HER-PHASEMS the mean age is 3.110 year and there is 23 male and 6 female patients in the normal kidney in our study eau 22  neo  統 ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ ฆ and the mean length of hydronemia�ur  ѐ ஆ ฏ ஆ ஆ ஆ ஆ ஆ ஆ ஆ... moreover similar 3.7.1.2 7.1 1 4 centimeter and for less than one year the mean కాక్మ్ రోది దమ్నివా కెటిక్చెంపికి సెధ్దాసంవా పరరనికాక్దాసడి కూబర్రలా, రాపరసీాకి కిలుత్క్నిక్ది స్పిరిసచిపెటీకెద్దాక్ నాడిర౛వా నంటిరౕములవడాళికోాఎందా. గఎటతదమా. మారౕిస్సుందిదర. ఀతిజి నారఋారతన నారౙంద 댓 నమికె. నటోదికొణం తారమందచిలి. two obstructive pattern we found that the RIVALO.76 which is the higher, this is a high obstructive feature and then on the DTPS also there is source obstructive which is true positive case of obstructive hydrolysis. So we conclude that the adequate ensuring adequate hydration is essential for increasing the dynamics of RIVALO estimation for determining the obstructive non-obstructive hydrolysis. And the risk of increase significantly decreases the function of age and the donor also assessment is useful for differentiating obstructive and non-obstructive hydrolysis. It can also be used as screening tool and for the non-indexic, ionic, non-ionic and non-indexic already for the dynamic keraloscintigraphy which that dynamic keraloscintigraphy is an ionizing one and many hospitals do not have that specificities with high level of sensitivity doctor sound can we detect the higher RIVALO in obstructive system and avoid unnecessary delay in the intervention. But the limitation of the sample size of our study is small and the RIVALO is a very non-specific parameter because the obstructions are not the only cause of the elevated RIVALO as we previously mentioned that the renal medical disease known present setting or non-medical disease the elevated RIVALO is also there. It can be also obstruction or need to RND and the Doppler study being an operative development has its own limitation. We did it. This is my six references. Thank you.
