Diuresis Renography Kidney Seeper In Diagnosis And Prognosis Of Chronic Obstructive Nephropathy And Correlation Studies

AIM:1. Diuresis renography in differentiating obstructive and clinical significance of non obstructive hydronephrosis.2. Evaluation of diuresis renography your assessment of renal function, has to decide whether to keep suffering from kidney.METHODS:This study selected the second hospital of shanxi medical university from June2012to March2013outpatient and hospitalization in patients with urinary tract colour to exceed a side renal function, and45cases of the contralateral kidney seeper in45side kidney and ureter.1. For all patients to conduct a comprehensive system of inspection, is clear about the cause.2.Diuresis renography inspections to these patients, determination of kidney and kidney function according to the result of image curve, combined with precise diagnosis patients, calculate the diuresis renography in the diagnosis of obstructive and the positive rate of non obstructive hydronephrosis.3. Obstruction in patients with partial obstruction and fully according to the determination of diuresis renography renal function indexes, according to the standard is divided into light, medium, heavy three groups.4. Of the three groups of patients for surgery or other ways to remove obstruction.5. Three months after review diuresis renography and record-kidney function.6. Comparison between groups before and after surgery average GFR values, using the paired t test, to determine to what extent renal damage, can be directly removed of kidney, do not need to relieve obstruction.RESULTS:.(1). Diuresis renography can accurately distinguish between obstructed and non obstructive hydronephrosis.The diagnosis rate was84.4%(2). When kidney damaged (GFR<10ml/min/1.73m2), no significant change in renal function after remove obstruction, if the contralateral function good, can choose to remove kidney, prevention of renal complications such as recurrent infections.CONCLUSION:(1) Diuresis renography in diagnosis of obstructive and non obstructive renal pelvis expansion has important significance.(2). Diuresis renography is able to accurately according to the test results to evaluate risk of renal function, has decided whether to keep suffering from renal surgery.
