Correlations Study On Intravenous Phelogram With The Constituent Concentration Of Urine In The Pelvis Of Ureter

Objective:To explore the relation between intravenous phelogram(IVP)and renal function of hydronephrotic kidney by researching the correlation of the class of IVP and the constituent concentration of urine in the pelvis of ureterMethods:Thirty-two patients with partial unilateral ureteral obstruction were examined by IVP and we collected the urine in the hydronephrotic pelvis of ureter。We measured the constituent concentration of urine in the pelvis of ureter which contained sodium ion,magnesium ion,chloridion,chloridion,endothelin(ET),urinary albumin,urinaryβ2-microglobulin and creatinine.And then we analysis the relation among the constituent concentration of urine in the pelvis of ureter,case history and IVPResults:(1)The constituent concentration of urine in the hydronephrotic pelvis of ureter were bigger than of cystic's urine.(2)The hydronephrotic patients' constituent concentration of urine in the pelvis of ureter with shorter case history were bigger than the patients' with longer case history.(3)The hydronephrotic patients' constituent concentration of urine in the pelvis of ureter with greater grade of IVP were bigger than the patients' with smaller grade of IVP.(4)Only power of hydrogen hydrogenion concentration(PH)had correlation with the case history and the grade of IVP and the coefficient correlation respectively was 0.45 and 0.40Conclusion:(1)Urine concentration ability of nephric tubule is augmented in early stage/mild hydronephrosis.It is benefit for reducing the pressure of nephric tubule.This could keep the fluid flow and keep some glomerular filtration rate(GFR).All is a kind of compensatory action.The increasing of uric ion concentration of renal pelvis shows that the kidney is in the stage of compensatory action.But in late stage/severe hydronephrosis,the pressure of nephric tubule will be increasing and the decreasing of uric ion concentration of renal pelvis shows that the urine concentration ability of nephric tubule is obviously weak and GFR is low.Renal function is acutely injured.We can regularly measure uric concentration of renal pelvis of hydronephrotic patients by upper urinary tract obstruction to prognosis and appraise renal function.(2)PH has linear correlation with the case history and the grade of IVP.The bigger pH is,the higher alkalinity of urine of renal pelvis is.That means the function of secreting hydrogen is weaker.Our research shows the value pH can appreciate the renal function.(3)IVP can not only show the renal filtration function,but also can appreciate the renal filtration function.So we should consider the dense and light of the IVP's images when appreciating the renal function.(4)In aspect of appreciating the renal function,we also should consider measuring the uric ion and bioactive substance concentration of renal pelvis.
